Intelligent combined protection assembly with external series trigger type overvoltage protection gap

An intelligent combined protection assembly with an external series trigger type overvoltage protection gap is formed by connecting the trigger type overvoltage protection gap and a voltage limiting type zinc oxide lightning arrester in series. The trigger type overvoltage protection gap adopts a triggering mode of discharging on the surface of an annular insulating medium material, and the trigger type overvoltage protection gap can be automatically coupled with the energy of overvoltage, so that under the condition that the AC/DC normal withstand voltage is not reduced, the lightning impulse breakdown voltage of the intelligent combined protection assembly with the external serial trigger type overvoltage protection gap can be reduced, and the response time to overvoltage is shortened; and the voltage limiting type zinc oxide lightning arrester unit is formed by connecting a group of zinc oxide nonlinear resistor discs in series, and is fixedly arranged in an insulating umbrella skirt jacket through insulat
