Summary
        VS1-24 type indoor high voltage vacuum circuit breaker is an indoor switchgear of three-phase AC 50 Hz power system with rated voltage of 24 kV, which is used as the protection and control unit of power grid equipment and power equipment of industrial and mining enterprises. It is suitable for frequent operation under rated working current, or multiple breaking of short-circuit current.
The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit.
        VS1-24 indoor high voltage vacuum circuit breaker is improved on the basis of ABB vd4-24. The circuit breaker still adopts composite insulation structure, but the redesign increases the insulation < br / >
Main structural features
1. The main circuit adopts composite insulation, small size, space saving, and can effectively protect the vacuum interrupter from impact and collision.
2. The vacuum interrupter shall be selected from the first-class domestic manufacturers, and the vacuum interrupter imported from home and abroad can be installed according to the user's requirements.
3. It 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 product model issuing certificate and model using certificate are complete.
5. Mechanical life 20000 times.
6. Through the capacitor switching capacity test, there is no reignition.
8. It can be used in prototype area with voltage of 12kV and altitude of 4500m.
