A new material to improve arc cooling efficiency
There are different ways to improve the short circuit breaking ability of MCB products at different stages.According to our experience, the selection of suitable thermoplastic material can shorten the cooling time before arc and improve the efficiency of circuit breaker, so as to improve the perf...Read more -
Optimized Design of a Kind of Mini Earth Leakage Circuit Breaker
The design of arc-extinguishing systems, as well as electronic module boards, was improved with staggered multichip in the arc extinguish chamber, multilayer mesh piece at the outlet spraying arc and major arc curvature structure for the piece causing arc. Two magnetoconductivity pieces wer...Read more -
The arc can be more quickly led to the arc extinguish chamber with the improvement when the breaking arc is happened.
Based on the original structure Of the miniature circuit breaker (MCB），an improvement method to quicken arc extinction is present in this paper. An arc-guiding Plate is added to the magnet yoke in arc extinguish chamber. The arc can be more quickly led to the arc extinguish chamber with the imp...Read more -
Simulation and Experimental Analysis of Arc Extinguish Chamber in Miniature Circuit Breaker
For a certain product of miniature circuit breakers, a 3D arc extinguish chamber model was built and the dynamic characteristic simulation was calculated. The simulation results revealed the movement rule of arc in the chamber. Firstly the arc roo ts transferred from contacts to a...Read more
