Fixed Type High Voltage Switchgear Switch Cabinet

KYN28-12 armoured medium mounted metal enclosed switchgear is suitable for 3.6-12kv three-phase AC power grids, used for receiving and distributing electric energy and controlling, monitoring and protecting circuits. It can be used in the bus section system of single bus, single bus or double bus system.

Functional units of high-voltage switchgear:

1. Main busbar room (generally arranged in two structures: "pin" or "1")

2. Circuit breaker room

3. Cable room

4. Relay and instrument room

5. Cabinet top small busbar room

6. Secondary terminal compartment

3、 Functions of the switchgear

The switchgear has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and busbar connection.

4、 Composition of switchgear

The switchgear should meet the relevant requirements of GB3906-1991 "3-35 kV AC Metal Enclosed Switchgear" standard, consisting of two parts: the cabinet body and circuit breaker. The cabinet body is composed of a shell, electrical components (including insulation parts), various mechanisms, secondary terminals, and wiring.

Five prevention measures for high-voltage switchgear

1. After the vacuum circuit breaker car inside the high-voltage switchgear is closed in the test position, the car circuit breaker cannot enter the working position. (Prevent load closing)

2. When the grounding switch inside the high-voltage switchgear is in the closed position, the car circuit breaker cannot be closed. (Prevent closing with grounding wire)

3. When the vacuum circuit breaker inside the high-voltage switchgear is closed, the back door of the panel and cabinet is locked with a mechanical device on the grounding knife. (To prevent accidental entry into live compartments)

4. The vacuum circuit breaker inside the high-voltage switchgear is closed during operation, and the grounding switch cannot be put into operation. (Prevent live hanging of grounding wires)

5. The vacuum circuit breaker inside the high-voltage switchgear cannot exit the working position of the trolley circuit breaker when it is working and closing. (To prevent loaded knife brakes)
