Description
Technical Field
The invention relates to the technical field of circuit breakers, in particular to a gas blowing arc-extinguishing device of a gas circuit breaker.
Background
A gas circuit breaker is used to interrupt a current flowing through a power supply line of a power system. The gas circuit breaker is disposed on a power supply line in order to interrupt a current flowing when a system accident occurs and a system in which the accident occurs is disconnected. As such a gas circuit breaker, a puffer type gas circuit breaker is widely used, and the puffer type gas circuit breaker has a pair of electrodes arranged to face each other in a closed vessel filled with an arc-extinguishing gas. The pair of electrodes are driven to open and close by a driving device disposed outside the gas circuit breaker.
