In power system, high voltage reactive power switching switch is an important control unit, which is an important tool to start the connection of power equipment. In order to ensure the safe operation of high-voltage reactive power switching switch, this paper proposes a new method for live detection of contact ablation degree of high-voltage reactive power switching switch to solve the lack of effective detection and evaluation means of contact ablation degree of high-voltage reactive power switching switch in power system. During the opening and closing process of high voltage reactive power switching switch, RF electromagnetic wave signal will be radiated, which contains information reflecting the ablation degree of contact. In this paper, through the detection and analysis of electromagnetic wave signal, the detection of contact ablation degree of high voltage reactive power switching switch is realized. This paper analyzes the influencing factors of radiated electromagnetic wave in the process of circuit breaker opening and closing. The anti-interference method of electromagnetic wave field detection is used to realize the live detection of contact ablation degree of high voltage reactive power switching switch. It effectively solves the problem of mutation detection of contact ablation degree of high voltage reactive power switching switch, and greatly improves the detection rate of contact ablation degree defects.
