35kv high voltage switch cabinet, also known as 35kv high voltage switch cabinet, 35kv armored metal high voltage switch cabinet, is a relatively large high and low voltage switch cabinet equipment. As a qualified power person, we must know all the knowledge of 35kv high voltage switchgear, the following by zhongyi electric to explain the 35kv high voltage switchgear.

1. Structural analysis of 35kv high-voltage switchgear:

The high voltage switch cabinet is composed of two parts: the cabinet body and the middle type extractable part (namely the hand cart). The main electrical components of the switch cabinet have their independent compartments, namely: hand compartment, bus compartment, cable compartment and instrument compartment. With overhead input-outlet line, cable input-outlet line and other functional schemes, after arrangement, combination can meet the requirements of various schemes of distribution equipment.

How to push and exit the switch cabinet?

All kinds of handcart adopt screw rod to advance and exit, its operation is light and flexible. When the hand truck needs to move from the cabinet, use a special lift transfer vehicle, it can be easily taken out, for all kinds of inspection, maintenance; As the circuit breaker is designed in the middle structure, the whole car is small in size and convenient for inspection and maintenance. When the hand vehicle is transferred into the cabinet circuit breaker room, it can be reliably locked in the open position/experimental position. Insert 2 times after controlling plug, cabinet put oneself in another's position shows lamp or position display to show its position, and only after safety lock, ability shakes to push mechanism, push hand car to working position. When the handcart reaches the working position, the push handle cannot be shaken any more, and the corresponding position display light or position display will show its position.

Iii. Operation instructions of 35kv high-voltage switchgear:

1. When entering the operation site, necessary safety protective articles must be worn according to the requirements of electric power safety working procedures.

2. Before starting the work, check the items listed in the "on-site service safety inspection list" one by one, and start the work after confirmation.

3. Strictly abide by the safety matters specified in the site service operation instruction, and provide on-site services.

4, in strict accordance with the power industry work ticket system implementation, requires the guardian in place. Transmission of electricity must be carried out by full-time personnel, prohibit unauthorized operation of switchgear, must strictly abide by the relevant rules of the power department.

5, although the switchgear design can guarantee normal operating procedures of interlocking switchgear parts, but the operator to various parts of the switchgear into and exit from operation, still should be in strict accordance with the procedures and the requirements of the technical documentation, should not be optional operation, more should not be stuck in operation without analysis to operation, otherwise, easy to cause equipment damage, even cause accidents.

4. What are the maintenance projects and cycles?

Maintenance can keep the switchgear running trouble-free and achieve the longest service life possible. Switch cabinet maintenance includes the following closely related tasks:

A. Daily inspection: confirmation of actual operation conditions;

B. Regular maintenance: measures to maintain the specified operation condition;

C. Overhaul: measures to restore the specified operation condition.

V. common faults of 35kv high-voltage switchgear in operation:

1. Common faults of high voltage switchgear mainly include sudden tripping of running equipment and failure of opening and closing of electric manual. Can be divided into electrical failure and mechanical failure.

2, electrical failure is mainly divided into electric energy storage, electric cannot close, electric cannot open, etc.

3. Judgment of sudden trip fault: the fault reason can be judged according to relay discards, remote signal information, etc.

4. Processing method: the switch trip is caused by the action of overcurrent relay, because of the line overload. The bus, transformer and circuit shall be checked when the trip is stopped at a high speed. Find the fault point of the short circuit, the fault can be removed before power.

Main products: baoding dry type transformer, baoding box type transformer, baoding oil immersed transformer, baoding high and low voltage complete sets of equipment. I companies to follow "detail decides success or failure, honesty molded the future" of the enterprise purpose, adhere to "quality measuring market, seek development by innovation, to management for efficiency" business philosophy, to make my company's products are widely used in power plant, chemical, construction, mining, metallurgy, rail transportation and other industries, to meet the needs of various users, my company rely on superior product quality, thoughtful service, won the trust of our customers.
