Features:
1. The circuit breaker adopts a three-phase pillar structure, which has the characteristics of breaking performance, stability and reliability, no danger of combustion and explosion, maintenance-free, small size, light weight and long service life.
2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture-proof and anti-condensation performance, and is especially suitable for use in severe cold or humid areas.
3. Three-phase pillars and current transformers are insulated by imported outdoor epoxy resin solids, which have the characteristics of high and low temperature resistance, ultraviolet resistance and aging resistance.
4. The operating mechanism adopts a miniaturized pop-up operating mechanism, which has low energy consumption for opening and closing; the mechanism transmission adopts direct transmission mode, with fewer opening and closing parts and high reliability. The operating mechanism is in a sealed mechanism box, which solves the problem of mechanism corrosion and improves the reliability of the mechanism.
5. The opening and closing operations of the circuit breaker can be operated manually or electrically or remotely. It can be matched with the controller to realize power distribution automation, and can also be combined with the recloser controller to form a recloser.
6. The circuit breaker can be equipped with two-phase or three-phase CT for automatic over-current tripping protection and intelligent control for information analysis. .
7. The circuit breaker can be equipped with isolating switch and three-phase linkage. There is an obvious visible fracture when the isolating switch is in the off state, and it has an anti-mistake interlock with the circuit breaker body. It can be connected with a surge arrester post insulator for easy and safe maintenance.
