structure

The main structure of the vacuum circuit breaker is the three-phase pillar type of the box, which is mainly composed of the conductive arc extinguishing system

Flange system, drive system, spring operating mechanism (electric or manual), housing and other six parts.

The external structure and installation dimension of circuit breaker are shown in Figure 1 and Figure 2.

Outdoor vacuum reclosing circuit breaker equipped with vacuum arcing chamber has stable and reliable opening performance and no fire

Fire and explosion hazard, safety, maintenance - free, small size, light weight and long service life.

The circuit breaker adopts a fully closed structure with good sealing performance, which is helpful to improve the moisture-proof and anti-condensation performance.Suitable for use in hot and humid areas.

According to user requirements, the 50/5~600/5 current transformer can be installed, and the output secondary current can be intelligently controlled

The producer performs information analysis.

The closing and opening of the circuit breaker can be operated manually, electrically or remotely.

The operating mechanism is sealed inside the switch box, which can effectively prevent the switch from being exposed to outdoor environment for a long time

And the mechanism caused by corrosion. The operation mechanism is novel, simple, reliable, small size, and the mechanical life can reach more than 10,000 times.

Outdoor isolation switch and circuit breaker can be installed to form a body. Circuit breaker and isolation switch have reliable mechanical interlock device.
