What is the role of the circuit breaker
In general, the circuit breaker itself does not exist lubrication problems, the need for lubrication is often its operating mechanism
Excellent arc suppression capability and good effect.
From the fact that the circuit breaker is a switch, it and other common switch of the main points are: 1. Applicable voltage level 2. Arc medium and way, there are vacuum, less oil, oil and sulfur hexafluoride, etc
In the event of system failure with the protection device and automatic device to match, quickly cut off the fault current, to prevent the accident to expand, so as to ensure the safe operation of the system.
Under normal circumstances, turn on and off the high voltage circuit in the no-load and load current.
