1. The main circuit adopts fixed sealing pole
The main circuit of the circuit breaker adopts APG process molding technology, and high-performance epoxy resin is used to seal the vacuum arc extinguishing chamber and the upper and lower outgoing lines together, so that the vacuum arc extinguishing chamber is free from the influence of dust, moisture and pollution, and the environmental adaptability and insulation reliability are improved.
2. There are umbrella groups between the upper and lower outgoing lines of the fixed pole
The umbrella group is designed between the upper and lower outgoing lines of the fixed pole, which increases the creepage distance of the external insulation between the fractures and improves the insulation reliability of the circuit breaker.
3. The circuit breaker is M2 pole circuit breaker
With superior mechanism performance, it can be used in frequent operation occasions. The circuit breaker meets the requirements of M2 circuit breaker, and the mechanical life is up to 20000 times. (the data comes from the inspection (Experiment) report of the national electrical product quality supervision and Inspection Center (no:19K2235-S))
4. The circuit breaker is E2 level circuit breaker
The circuit breaker passed all type tests in Shanghai high voltage apparatus testing center and met the requirements of E2 level circuit breaker. The low current circuit breaker cut off the full capacity short-circuit current for 30 times, and the high current circuit breaker cut off the full capacity short-circuit current for 20 times.
5. The circuit breaker is a C2 level circuit breaker
In the process of capacitive current breaking, the circuit breaker has a very low probability of re striking, which meets the requirements of class C2 circuit breaker.
6. The circuit breaker mechanism has excellent anti-corrosion function
The mechanism parts adopt advanced surface treatment technology, which makes the parts have stronger corrosion resistance and higher mechanical stability.
7. Adopt buffer with excellent cushioning performance
The specially designed buffer reduces the opening overshoot and opening rebound of the circuit breaker, and improves the mechanical life of the circuit breaker.
8. Insulated tie rod made of BMC material
The insulating material of the insulating rod is BMC, which not only meets the requirements of mechanical strength, but also has a large creepage distance along the surface, which improves the insulation performance of the circuit breaker.
9. The circuit breaker can be used at -25 ℃
The circuit breaker adopts special low-temperature grease and buffer that can work at low temperature, so that the circuit breaker can be used at -25 ℃.
