How to draw up an annual schedule for the maintenance of electrical equipment? I will try to answer this question in detail in today's post.

It's not a secret for anyone that the main document by which the repair of electrical equipment is carried out is the annual schedule of preventive maintenance of electrical equipment, on the basis of which the need for repair personnel, materials, spare parts, and components is determined. It includes each unit subject to major and current repairs of electrical equipment.

To draw up an annual preventive maintenance schedule (PPR schedule) for electrical equipment, we need standards for the frequency of equipment repairs. These data can be found in the manufacturer's passport data for electrical equipment, if the plant specifically regulates this, or use the reference book "System for maintenance and repair of power equipment". I use A.I. FMD in 2008, therefore, I will refer to this source further.

So. Your household has a certain amount of power equipment. All this equipment must be included in the PPR schedule. But first, some general information about the annual PPR schedule.

Column 1 indicates the name of the equipment, as a rule, brief and understandable information about the equipment, for example, name and type, power, manufacturer, etc. Column 2 - number according to the scheme (inventory number). I often use numbers from electrical single-line diagrams or from technological ones. Columns 3-5 indicate the resource standards between major repairs and current ones. Columns 6-10 indicate the dates of the last major and current repairs. In columns 11-22, each of which corresponds to one month, the symbol indicates: K - capital, T - current. In columns 23 and 24, respectively, the annual downtime of equipment in repair and the annual fund of working hours are recorded. Now that we have considered the general provisions on the PPR schedule, let's consider a specific example. Let's assume that in our electrical facilities, in building 541, we have: 1) a three-phase two-winding oil transformer (T-1 according to the scheme) 6 / 0.4 kV, 1000 kVA; 2) pump motor, asynchronous (designation according to the scheme H-1), Рн=125 kW;

Step 1. We enter our equipment into the empty form of the PPR schedule.

Step 2 At this stage, we determine the resource standards between repairs and downtime:

a) For our transformer: we open the reference book p. 205 and in the table "Standards for the frequency, duration and complexity of repair of transformers and complete substations" we find a description of the equipment that fits our transformer. For our power of 1000 kVA, we select the values ​​​​of the frequency of repairs and downtime during major and current repairs, and write them down in our schedule.

b) For an electric motor according to the same scheme - page 151 Table 7.1 (see figure).

We transfer the found standards in the tables to our PPR schedule

Step 3 For the selected electrical equipment, we need to determine the number and type of repairs in the coming year. To do this, we need to determine the dates of the last repairs - major and current. Suppose we are making a schedule for 2011. The equipment is operational, the dates of repairs are known to us. For T-1, a major overhaul was carried out in January 2005, the current one - in January 2008. For the pump engine N-1, the capital one is September 2009, the current one is March 2010. We enter this data into the chart.

We determine when and what types of repairs are due for the T-1 transformer in 2011. As we know there are 8640 hours in a year. We take the found resource standard between major repairs for the T-1 transformer 103680 h and divide it by the number of hours in a year 8640 h. We calculate 103680/8640 = 12 years. Thus, the next overhaul should be carried out 12 years after the last overhaul, and since. the last one was in January 2005, which means that the next one is planned for January 2017. For current repairs, the same principle of operation: 25920/8640=3 years. The last maintenance was carried out in January 2008, thus. 2008+3=2011. The next current repair is in January 2011, it is for this year that we draw up a schedule, therefore, in column 8 (January) we enter “T” for the T-1 transformer.

For the electric motor we get; major repairs are carried out every 6 years and are planned for September 2015. The current one is held 2 times a year (every 6 months) and, according to the latest current repairs, we plan for March and September 2011. Important note: if the electrical equipment is newly mounted, then all types of repairs, as a rule, "dance" from the date the equipment was put into operation.

Our chart looks like this:

Step 4 We determine the annual downtime for repairs. For a transformer, it will be equal to 8 hours, because. in 2011, we planned one current repair, and in the resource norms for current repairs, the denominator is 8 hours. For the N-1 electric motor in 2011 there will be two current repairs, the downtime rate in the current repair is 10 hours. Multiply 10 hours by 2 and get an annual downtime equal to 20 hours. In the column of the annual working time fund, we indicate the number of hours that this equipment will be in operation, minus downtime for repairs. We get the final form of our graph.

Important note: at some enterprises, power engineers in their annual PPR schedules, instead of the last two columns of annual downtime and the annual fund, indicate only one column - “Labor intensity, man * hour”. This labor intensity is calculated according to the number of pieces of equipment and the norms of labor intensity of one repair. This scheme is convenient when working with contractors performing repair work.

Do not forget that the dates of repairs must be coordinated with the mechanical service and, if necessary, the instrumentation and control service, as well as with other structural units that are directly related to the repair and maintenance of related equipment.

If you have any questions about the preparation of the annual PPR schedule, ask questions, I will try, if possible, to answer them in detail.

Purpose: to learn how to calculate the frequency of scheduled maintenance and repair work. Draw up an annual plan - a schedule for the maintenance of equipment.

Progress:

1. Select the equipment number according to the option (see Appendix 1)
2. We enter our equipment into the empty form of the PPR schedule.
3. At this stage, we determine the resource standards between repairs and downtime:
4. We look at Appendix No. 1 “Standards for the frequency, duration and complexity of repairs”, select the values ​​\u200b\u200bof the frequency of repairs and downtime during major and current repairs, and write them down in your schedule.
5. For the selected equipment, we need to determine the number and type of repairs in the coming year. To do this, we need to determine the number of equipment hours worked (the calculation is conditionally carried out from January) (see Appendix 2)
6. 4. We determine the annual downtime in repairs
7. In the column of the annual working time fund, we indicate the number of hours that this equipment will be in operation, minus downtime for repairs.
8. Draw a conclusion

Theoretical part

Scheduled preventive maintenance (PPR) - This is a complex of organizational and technical measures for supervision, maintenance and all types of repairs, which are carried out periodically according to a predetermined plan.

Thanks to this, premature wear of equipment is prevented, accidents are eliminated and prevented, fire protection systems are maintained in constant operational readiness.

The preventive maintenance system includes the following types of technical repairs and maintenance:

weekly maintenance,

monthly maintenance,

annual scheduled preventive maintenance,

Annual scheduled preventive maintenance is carried out in accordance with the annual equipment maintenance schedule.

Drawing up a PPR schedule

The annual preventive maintenance schedule, on the basis of which the need for repair personnel, materials, spare parts, and components is determined. It includes each unit subject to major and current repairs.

To draw up an annual preventive maintenance schedule (PPR schedule), we need standards for the frequency of equipment repairs. These data can be found in the manufacturer's passport data, if the plant specifically regulates this, or use the "Maintenance and Repair System" reference book.

There is some equipment. All this equipment must be included in the PPR schedule.

Column 1 indicates the name of the equipment, as a rule, brief and understandable information about the equipment.

In column 2 - the number of equipment

In column 3-4 - indicate the resource standards between major repairs and current ones. (See Appendix 2)

Columns 5-6 - the complexity of one repair (see Table 2 Appendix 3) based on the list of defects.

In columns 7-8 - the dates of the last major and current repairs are indicated (we conditionally accept the month of January of the current year)

In columns 9-20, each of which corresponds to one month, the symbol indicates the type of planned repair: K - capital, T - current.

In columns 21 and 22, respectively, the annual downtime of equipment in repair and the annual fund of working hours are recorded.

Question from Dmitry:

Hello! Please tell me if there are any regulatory requirements for the inspection and maintenance of supply and exhaust ventilation and air conditioners in a private medical center, what kind of supervision monitors (checks) this? What is the frequency of such checks and maintenance?

Reply to Dmitry:

Hello Dmitry.

According to clause 3.1.1. GOST 12.4.021-75 SSBT. Ventilation systems. General requirements for operation Ventilation systems are allowed that have fully completed commissioning and have operating instructions in accordance with GOST 2.601-2006, passports, repair and operation logs. The operating instructions for ventilation systems should reflect the issues of explosion and fire safety. Scheduled inspections and checks of compliance of ventilation systems with the requirements of this standard should be carried out in accordance with the schedule approved by the administration of the facility (clause 3.1.2. GOST 12.4.021-75). Preventive inspections of rooms for ventilation equipment, cleaning devices and other elements of ventilation systems serving rooms of categories A, B and C should be carried out at least once per shift with the results of the inspection recorded in the operation log. The faults detected in this case are subject to immediate elimination (clause 3.1.3 of GOST 12.4.021-75). Cleaning of ventilation systems must be carried out within the time limits established by the operating instructions. A mark on cleaning is entered in the journal of repair and operation of the system (clause 3.2.7. GOST 12.4.021-75). You will find the form of the log for the repair and operation of ventilation systems in Appendix 10 of RD 34.21.527-95 “Typical instructions for the operation of heating and ventilation systems of thermal power plants”.

The efficiency of the ventilation system in medical facilities should be checked once a year.

Rationale:

Heating, ventilation and air conditioning systems must provide normalized parameters of the microclimate and air environment of the premises in which medical activities are carried out. One of the most important elements of any building is the supply and exhaust ventilation system with mechanical and (or) natural motivation. The mechanical supply and exhaust ventilation system must be certified (clause 6.5 of SanPiN 2.1.3.2630-10 "Sanitary and epidemiological requirements for organizations engaged in medical activities") (hereinafter - SanPiN 2.1.3.2630-10). Quite often there is a violation associated with the operation of the supply and exhaust ventilation system - failure to check the effectiveness of its operation, which does not meet the requirements of clause 6.5 of SanPiN 2.1.3.2630-10. By virtue of this norm, once a year, an inspection of the efficiency of work, current repairs (if necessary), as well as cleaning and disinfection of mechanical supply and exhaust ventilation and air conditioning systems should be carried out.

In accordance with clause 11.2. STO NOSTROY 2.24.2-2011 “Internal engineering networks of buildings and structures. Ventilation and air conditioning. Testing and adjustment of ventilation and air conditioning systems ”(hereinafter - STO NOSTROY 2.24.2-2011) when operating heating and ventilation systems, you must have:
- passports of the established form for thermal units, heat consumption systems and ventilation installations with protocols and acts of inspections and repairs;
- working drawings of equipment;
- executive diagrams of the thermal unit and pipelines with the numbering of fittings and equipment, the arrangement of instrumentation and automation;
- logs of operation of heating and ventilation systems;
-factory instructions for maintenance of heat consumption and ventilation systems;
- job descriptions for service personnel.

According to clause 11.3. STO NOSTROY 2.24.2-2011 factory instructions must contain:
- a brief description of the system or equipment;
- starting, shutdown and maintenance procedures during normal operation and measures to be taken in case of emergency;
- the procedure for admission to inspection, repair and testing of the system or equipment;
- safety and fire safety requirements specific to a given system or installation.

The factory instructions for the operation of heating and ventilation systems should reflect the specific actions of personnel to eliminate system malfunctions, taking into account their nature and place of occurrence, the purpose of the serviced premises, the degree of influence of malfunctions on the operability of process equipment and the safety of maintenance personnel (clause 11.4 STO NOSTROY 2.24 .2-2011).

When carrying out scheduled preventive repairs, the following documentation should be drawn up (clause 11.5 of STO NOSTROY 2.24.2-2011):
- annual and monthly repair plans for heating and ventilation systems;
- statements of defects and scope of work, estimates (if necessary);
- the schedule of carrying out and the project of the organization of repair;
-necessary repair documentation;
- when carrying out works on reconstruction or modernization
— approved technical documentation.
