Abstract

The purpose of invention provides a kind of gaseous insulation switch device for effectively eliminating the surge voltage. In the device, the said insulation contact to the metal container is made with components with nonlinear voltage formed with nonlinear voltage impedance including zinc oxide of 85 to 95%. The nonlinear voltage component has a through-hole disk in the center and fromed the electrodes on both sides of one face of the said through-hole and form high capacitor layer on inner and outer side of the said disk and the reinforcing board of through-hole fixed integrally at least on one side of the said electrode. So, the small type of surge eliminating means can effectively eliminate high frequency surge for the voltage insulation of commercial frequency.
