Abroad CIRCUIT BREAKER gas Arc extinguishing Assembly
Mar 05, 2015Basically a circuit breaker consists of a fixed and a moving contact. If there is a single set of fixed moving coil and the circuit breaker is connected in a single phase then it is called single pole circuit breaker. Similarly different pole circuit breakers exist depending upon the number of sets of fixed and moving contacts. Each pole consists of an arc extinguishing chamber. If the arc is not extinguished, …

66KV sf6 gas Low pressure Custom software
20/6/2016Again, I would be surprised to see an air blast breaker that didn't close itself on low low gas, just like I would be surprised to see an SF6 not trip itself on low low. Great discussion either way. It's interesting to see how different companies use the same equipment in different ways for different reasons.
