Application of BIS-2110 Device for detecting action characteristics of High Voltage Circuit Breaker

with the continuous improvement of power supply reliability requirements, the routine maintenance mode of high-voltage circuit breaker under the condition of power failure in the past cannot meet the current condition evaluation requirements of the circuit breaker. Therefore, in order to solve this problem, this paper introduces an on-line monitoring device for the action characteristics of high-voltage circuit breaker. It judges the state of the circuit breaker by monitoring the current change of the opening and closing coils in the process of action. Compare with the normal working state of circuit breaker, we can judge whether the circuit breaker is in good condition. So, we can find and deal with the hidden dangers in time to ensure the stable operation of the power grid.
