LW35-252(T) high voltage sf6 circuit breaker

Product description

LW35-252 since can type SF6 circuit breaker is my company independent development of a new generation of high voltage circuit breaker. The circuit breaker in arc extinguishing principle and structure and compared to traditional pneumatic type sulfur hexafluoride breaker had greatly improved. It makes full use of the heating effect of the arc to improve sulfur hexafluoride gas in the air cylinder pressure, make the circuit breaker tripping operation work needed for the short circuit current is reduced, thus can use all the spring operating mechanism. This type of circuit breaker design is reasonable, compact structure, technical performance has reached international level and domestic advanced level, is one of the traditional pneumatic sulfur hexafluoride breaker updated products, the main structure of the product is made up of three separate single pole circuit breaker, can monopole operation, but also electrical three-phase linkage.

Feature advantages

1, the circuit breaker is the latest design principles, the structure is simple, cover an area of an area small; Easy installation, low noise, high reliability;

2, circuit breaker wiring board for a variety of ways to decorate, make into the wire arrangement is flexible;

3, LW35-252 SF6 circuit breaker for the spring mechanism, compact structure, simple connection between institutions and ontology, circuit breaker mechanical characteristic determined by design structure, less field adjustment;

4, the arcing chamber using since can type arc extinguishing principle, using small diameter pressure cylinder, and two-way from the structure of gas blowing. Using the arc blocking effect improve the sulfur hexafluoride gas in the air cylinder pressure, and extinguished arc;

5, LW35-252 SF6 circuit breaker with CT spring operating mechanism, stable and reliable operation, little noise, high storage efficiency, storage time is not more than 15 seconds), suitable for various environmental conditions;

6, sulfur hexafluoride breaker LW35-252 type of static sealing system adopts double type O sealing form, the dynamic seal adopts double x-shaped seal form, reducing the sulfur hexafluoride gas leakage. For the convenience of the user observation, ontology USES pointer type SF6 gas density relay to monitor;

7, LW35-252 SF6 circuit breaker with CT spring operating mechanism, compared with the traditional hydraulic press no leakage of oil and gas, for the maintenance free operation. The circuit breaker is power supply system upgrade, establish ideal switch no leakage transformer substation equipment.
