Cause analysis on circuit breaker switch tripping coil burnt

In the course of the operation of high-voltage switch, every jump, closing coil burning occurred, mainly concentrated in the 10KV switch, especially in the process of closing. Due to economic reasons, 10KV switch structure is simple, relatively low reliability for the high voltage switch, switch their own self-protection measures are incomplete, this is 10KV switch failure more reasons, also, out of need to ensure reliable tripping of equipment failure, the high reliability of the switch tripping, therefore, coil burning mainly in the closing coil. Switch actuator internal problems: in the external circuit under normal circumstances, if there is problem inside the actuator, such as body jammed, caused by switch refused, causing the above consequences.
