Manufacturer standard China IP20 3p MCB Mini Circuit Breaker Epb10K Series

LW口-72.5/126/145 self- energy type sulfur hexafluoride circuit breaker is a new generation of high voltage circuit breaker independently developed by our company. Compared with the traditional compressed gas type sulfur hexafluoride circuit breaker, the circuit breaker has a great improvement in arc extinguishing principle. It makes full use of the energy of the arc itself, rotates and spreads the arc, and combines with the compressed air blowing arc, so that the arc extinguishing performance is greatly improved. Due to the combination of self- energy and compressed air, the diameter of the compressed air chamber can be significantly reduced, and the operating work required by the circuit breaker can be reduced, so that a spring operating mechanism with no oil and gas leakage and higher reliability can be used.At the same time, the operation noise is greatly reduced, which is most conducive to the transformation and use of the urban network. LW口-72.5/126/145 type self- energy SF6 circuit breaker is reasonable in design, compact in structure, and its technical performance has reached the domestic advanced level. It is a replacement product of traditional compressed SF6 circuit breaker. Optional CT20, CT27 spring operating mechanism, ABB type HMB-2 spring hydraulic operating mechanism, etc. LW□-72.5/126/145 type self- energy SF6 circuit breaker is suitable for 72.5kV- 145kV power system, used for protection and control of high voltage power transmission and transformation system. The circuit breaker fully meets the requirements of IEC56, IEC62271-100, GB1984, DL402 (ANSI C37: 60Hz) and related standards.
