Title:
GAS INSULATED HIGH VOLTAGE EQUIPMENT ENCLOSED IN METAL CUBICLE EQUIPPED WITH ARRESTOR
Document Type and Number:
Japanese Patent JPS62193074
Kind Code:
A
Abstract:
In a metal-encapsulated gas-insulated high-voltage installation with an overvoltage arrester which is arranged in a separate encapsulation and is connected via a gastight feedthrough to the conductor of the high-voltage installation, fault arcs can lead to heavy stresses of the overvoltage arrester by dynamic forces due to overloading. In order to prevent this, there are provided in the connection between the feedthrough and the overvoltage arrester two electrode-shaped support bodies, between which a flexible current-carrying ribbon is arranged. The cross section of the current-carrying ribbon is designed so that it melts at currents of a magnitude which is equal to or larger than that required for the pressure relief of the overvoltage arrester after the arc has been blown out of the arresting housing. Thereby, the overvoltage arrester and the feedthrough are mechanically decoupled.
