Product Description
VS1-24 indoor high-voltage vacuum circuit breaker is an indoor installation, three-phase AC 50HZ, rated voltage of 24KV substation and distribution control and protection equipment. It is used in AC systems of 24KV and below, and can be used for dividing and rating current and fault current, especially suitable for frequent operation, such as the combination of capacitors and switches, controlling electric furnaces, transformers and high-voltage motors, etc., and can also be used as a contact circuit breaker.
Features of VS1-24 vacuum circuit breaker:
VS1-24 indoor high-voltage vacuum circuit breaker is designed on the basis of ABB VD4-24, the circuit breaker still adopts a composite insulation structure, but the redesign increases the creepage distance and insulation thickness of the insulating cylinder to meet the insulation requirements of 24kV.
1. The main circuit is made of composite insulation, which is small in size, space-saving, and can effectively protect the vacuum interrupter from the impact and collision.
2. The vacuum interrupter is selected from domestic first-class manufacturers, and the vacuum interrupter imported at home and abroad can be installed according to user requirements.
3. Can be equipped with KYN28A-24 central cabinet.
4. The rated current is 630-3150A, the rated short-circuit breaking current is 20kA-31.5kA, and the model issuance certificate and model use certificate of the product are complete.
5. Mechanical life 20000 times.
6. Passed the capacitor switching capacitance test, and there was no re-ignition phenomenon.
8. It can meet the voltage of 12KV and the altitude of 4500 meters is used in the plateau area.
