High Voltage Vacuum Circuit Breakers

Introduction:

3AV5-12 type high voltage vacuum circuit breakers adopt ABB and SIEMENS' solid sealing insulation technology, and seal the vacuum interrupter and other parts of the primary main circuit with epoxy resin materials to form poles with high insulation and high mechanical strength to avoid It eliminates the impact of the harsh operating environment on the external insulation of the primary circuit, and realizes complete maintenance-free.

High voltage vacuum circuit breakers can be operated frequently, with multiple breaking and reclosing capabilities. The product is designed as a front and rear assembled structure, which can be used as a fixed installation unit or as a trolley unit matched with the chassis, and has a reliable interlocking function.

 

Features:

1. Adopt optimized spring operating mechanism, simple structure and stable performance

2. It can be used as the control and protection of electrical equipment in industrial and mining enterprises, power plants and substations, and is suitable for places with frequent operations.

3. The main circuit adopts solid-sealed poles, and the miniaturized operation panel saves space in the cabinet.
