Industrial High Voltage Switchgear

Industrial High Voltage Switchgear

KYN series metal-clad removable enclosed switch cabinet (called switch cabinet for short). It is applicable for power receiving

and distribution in the 3.6-12Kv three-phase AC 50Hz single bus bar and single bus bar sectioning system. It has the functions ofcontrolling, protecting and monitoring the circuit.

The cabinet structure of the industrial high voltage switchgear is made of aluminum-zinc plate by CNC machine tools. All operations are carried out with the door closed; high protection level can prevent the intrusion of debris and insects; simple and effective five-proof locking function to prevent misoperation. It can be equipped with VS1 and VD4 vacuum circuit breakers. It has the characteristics of simple replacement of the circuit breaker, good trolley interchangeability, wall installation and front maintenance of the cabinet, and also has a low floor space, enough space for the cable room, and multiple cable connections. Heaters can be installed in circuit breakers and cable compartments to prevent condensation and corrosion.

The switchgear equipment is 3.6-12KV, three-phase AC 50HZ single bus and single-line network segment of the complete set of power distribution devices produced by our company. Mainly used to control power plants, small and medium-sized generators, power distribution, industrial and mining enterprises, power supply plants of power secondary substations, power transmission and transformation, and protection and detection systems for large-scale high-voltage motors.

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)
