Intelligent switch type combined surge protection module in high-power-frequency overvoltage harsh power supply environment

The invention discloses an intelligent switch type combined surge protection module in a high-power-frequency overvoltage harsh power supply environment. The intelligent switch type combined surge protection module is formed by combining an intelligent control unit and a switch type surge protection unit, wherein the intelligent control unit is provided with an automatic overvoltage energy coupling trigger circuit and a controllable trigger switch, and can realize intelligent sensing and automatic gating of internal overvoltage such as power frequency overvoltage and operation overvoltage and external lightning overvoltage. Therefore, the intelligent switch type combined surge protection module has the remarkable characteristics of very high power frequency withstand voltage and high lightning voltage protection level, and can be applied to overvoltage protection of frequent and long-lasting high power frequency overvoltage scenes of a communication base station power supply and a base station main equipment
