The invention discloses a high-voltage switch control loop break area identification circuit and an identification method. The identification circuit comprises a switch control loop and a signal loop, wherein the switch control loop comprises a switching-on loop and a switching-off loop, a circuit breaking diagnosis circuit is additionally arranged in the switch control loop so as to diagnose whether a circuit in the switch control loop is broken, a switching-on monitoring relay and a switching-off monitoring relay are additionally arranged in the switch control loop to judge a circuit breaking area, a circuit breaking area signal is generated and displayed through the signal loop, whether circuit breaking area judgment is allowed is determined by the circuit breaking diagnosis circuit, and accordingly switch control loop break area identification motion logic is formed. According to the circuit, identification of the switch control loop break area is achieved, the first-air repair efficiency of a broken circuit is improved, first-air repair labor is saved, and circuit load loss is greatly reduced.
