Indoor 24 KV AC Metal-clad Electrical Switchgear

Indoor 24 KV AC Metal-clad Electrical Switchgear

Indoor AC metal-clad electrical switchgear is a complete power distribution equipment used for 3.6~24kV, three-phase AC50/60Hz, single bus and single bus section system. Mainly used for power transmission of small and medium generators in power plants; power reception and transmission of power distribution and substations in power systems of factories, mines and enterprises, and the start of large high-voltage motors to control, protect and monitor systems. The switchgear meets the requirements of IEC298, GB3906-91. In addition to the use of household VS1 vacuum circuit breakers, it can also be used with ABB's VD4, Siemens' ZN65A's Siemens 3AH5, GE's VB2, etc., to truly realize the good performance of the power distribution device.

In order to meet the requirements of wall-mounted installation and front-end maintenance, the switch cabinet is equipped with a special current transformer so that the operator can perform maintenance and inspection in front of the cabinet.

Service environment

1. Air temperature: -25℃~+40℃

2. Humidity: monthly average humidity 95%; daily average humidity 90%.

3. Altitude: ≤2500m

4. The surrounding air is obviously not polluted by corrosive and combustible gases, vapors, etc.

5. No frequent violent shaking

Fully type tested

The switchgear has passed all tests required by international (IEC) standards. Each switchgear unit must undergo routine factory testing before leaving the factory. These tests are designed to perform functional checks on the switchgear according to the specific characteristics of each installation.

Features

1: STRICT protection step to ensure personal safety

2: The cable room can be installed as many as 9 single-core cables

3: Operation and testing positions will be established for the handcart, and both positions are equipped with safe and reliable positioning device and display device

4: The enclosure is completely assembled from aluminized and galvanized steel plate, which are machined and bent by machine tool and then bolted.

5: It has high mechanical strength and its neatness and beauty is ensured.

6: The switchboard door is sprayed with plastic, also has strong capacity of impact resistance and corrosion protection.

7: The primary switch may be provided with VD4 vacuum circuit breaker and C3 series of fixed type load switch from ABB, various domestic vacuum circuit breakers (such as VS1, VH1, VK, ZN28) may also be provided in lieu of the same foreign products.

8: Front door is installed with a observation window to check the operating state of the components inside the room

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 the blade from being pulled under load)
