2.1.2. Terms of repair work should be determined with the following:

a) the composition of the brigade must match technological scheme Repair. The change in the composition of the brigade until the end of the repair is not allowed;

c) To ensure the implementation of the repair work on time, it is recommended to issue normalized task plans, the use of an aggregate-noded method of repair to use the Exchange Fund of the Parts;

d) The operation of the repair personnel must be subordinate to the maximum reduction in the duration of repair work.

2.1.3. Management provides for the composition of the repair brigade of 4 people: the 50th discharge electric surveyors - 1 person, the 3rd discharge - 2 people, the 2nd discharge - 1 person.

2.1.4. Labor costs on the overhaul of the switch are determined on the basis of "time standards for capital, current repairs and operational maintenance of equipment for 15 - 500 kV substations and distribution networks 0.4 - 20 kV, approved by the USSR Ministry of Energy in 1971

The norms on the overhaul of the oil switch MCP-35-1000-25 (without changing the inputs) - 41.8 people, with the change of inputs - 52 people-

2.2. Preparation for repair

2.2.1. Preparing for overhaul is made in accordance with the specific scope of work provided for this type equipment.

2.3.1. Control of the quality of repair work by the Contractor to implement in the following order:

a) Check together with the repair manager, the condition of each assembly unit during the repair. At the same time, the manager should provide guidance on the methods of repair and supplement, (clarify) technical requirements for repairs, on which an acceptance of a assembly unit will be carried out from repair and assessment of the quality of repair work;

b) completed hidden work and intermediate operations made to make a manager for acceptance and assessment of quality;

c) after the end of all repairs to prevent the switch for the final acceptance.

2.3.2. The final acceptance of the product is generally produced by representatives of the operational unit together with the repair manager, which the technical act of repair is drawn up, which is signed by representatives of both parties.

3. Acceptance of the switch to repair

Introduction

Introduction

The Organization Guide to the overhaul technology of the Oil Switch NMD-35/600 provides for the use of energy enterprises and other specialized enterprises of the most rational forms of the organization of repair work and advanced technological methods of their implementation.

The management is developed on the basis of the drawings and instructions of the manufacturer and the best practices of repair on a number of enterprises.

The guide has a strict sequence and scope of repair operations, regulatory materials on technology and labor costs for repair, qualifying staff of repair personnel, as well as recommendations for identifying defects of parts. A list of funds (tools, fixtures, fasteners, etc.) are required to perform repair work (applications 1, 2, 3 and 4).

The total costs of major overhaul of the same switch are 28.2 people, including directly for repair of 24.0 people, on the adjustment of the switch of 4.2 people-b.

The labor costs specified in operating cards cannot be used to determine the timing and cost of repair work, as they are not taken into account the time for preparatory and final work, downtime, break, rest, etc. This time is approximately 8.5% of the total time to repair the switch.

I. General provisions

This guide is intended for production enterprises as a regulatory document when planning, prepare and manufacturing repair work.

Since the management provides for the repair of all the switch nodes, then the total labor costs are higher than the regulatory. The volume of repair work can be reduced or increased by decision of the person responsible for the operation and repair of equipment, but actual labor costs should not exceed the normative.

Further improvement of this leadership, aimed at improving the quality, level of organization and production of repair work, to reduce repair time, will be carried out as the accumulation and adoption of new technological solutions.

Overhaul technology provides for the replacement of damaged or worn out parts.

Repair of details extending the downtime of equipment in repair is not recommended. Repair of such parts is carried out during the interremmer period using them in the future as an exchange fund of spare parts.

The manual provides for the inspection and repair of relay protection devices, automation, secondary switching chains and electrical testing staff of relevant services.

The labor costs provided in the manual are determined on the basis of "time standards for capital, current repairs and operational maintenance of equipment for 35-500 kV substation, approved by the USSR Ministry of Energy in 1971, and may be reduced by improving the organization and technology performed by repair work.

In the process of manufacturing work, repair personnel must strictly perform existing rules Safety.

Providing the conditions for the safe production of repair work is assigned to the operational (operational) personnel of the power grid and power plant.

II. Preparation for overhaul

Preparation for capital repairs should be carried out in accordance with the specific scope of work provided for this equipment.

The most rational is the following procedure for performing preparatory work:

- familiarization with the importance of repair work;

- familiarization with the events recommended by the factory instructions, the circulars of the Headtegrand of the USSR Ministry of Energy to improve the reliability of the equipment;

- familiarization with the documentation of previous repair work or installation;

- determination of the qualification and quantitative composition of the repair brigade;

- study with repair personnel instructions on the organization and technology of overhaul switch;

- Development of the planning plan of workplaces and placement of parts, nodes, devices and tools.

Before the start of repair work should be checked:

III. Organization of repair work

Repairs manages a representative of the repair unit (repair manager).

Acceptance of equipment from repair is made by operational services in accordance with existing provisions.

Terms of repair of equipment should be determined taking into account the following organizational activities:

- The composition of the brigade is determined by the circuit of the overhaul of the switch (Appendix 5 - see Plot). Changing the composition of the brigade until the end of work on individual nodes is not allowed;

- the operation of the repair personnel should be subordinated to the maximum reduction in the terms of repair work;

- To ensure the implementation of the repair work, it is recommended to issue normalized tasks, the use of an aggregate-noded method of repair and the use of the Exchange Fund of the Parts.

The end of the repair work is issued by a technical act (Annex 6) and is signed by representatives of repair and maintenance enterprises (services).

Instructions for amplifying switches by RIA cameras.
Improving the limit of shutdown current is achieved due to the application in new chambers effective system The multiple longitudinal blast with the symmetric arrangement of exhaust slots and installations in the chambers of spring-piston unloading tanks. The use of tanks allows you to limit the pressure in the chambers when the high short circuit current is disconnected, which reduces the load on the inputs and the foundation of the switch.
