Product Description
The main functions of the disconnecting switch:
1, after the switch, to establish a reliable insulation gap, will need to repair equipment or lines and power supply with a clear break point separated.
2. Switch circuits according to operation.
3, can be used to divide and close the line in the small current, such as bushing, bus, connector, short cable charging current, switching capacitor capacitor capacitor current.
4. The no-load excitation current can be used to divide and combine a certain capacity transformer.
5, isolation of power supply, high-voltage maintenance equipment and live equipment to disconnect, obviously visible point of disconnection. Isolation Switch features: 1, in the electrical equipment maintenance, to provide an electrical interval to protect the personal safety of maintenance personnel. 2, the disconnector can not take the load operation: can not take the rated load or the heavy load operation, can not divide, the combined load current and the short circuit current. 3, general power supply operation: first the isolation switch, after the circuit breaker or load switch. 4. The rated voltage, rated current, dynamic stable current, thermal stable current and so on must meet the needs of the use.
Disconnecting switch configuration:
1, both sides of the circuit breaker should be equipped with disconnecting switch, in order to form a clear break in the circuit breaker maintenance and power isolation.
2. Common Transformers which are directly grounded at neutral points shall be grounded through disconnecting switches.
3. The lightning arrester and voltage transformer on the bus should be combined with a group of disconnecting switches to ensure the safety of the maintenance of the electrical apparatus and the bus. 1-2 groups of grounding knife gates should be installed on each bus.
4. The arrester connected to the transformer lead wire or neutral point may not be equipped with the isolating switch. 5. When there is no power supply on the customer side of the feed line, the disconnecting switch can not be installed on the side of the circuit breaker leading to the customer. But in order to prevent lightning over-voltage, can also be installed.
