Abstract

The present invention discloses an optical voltage sensor mounting device for measuring GIS bus voltage, comprising a mounting device housing, a matching sensor bracket and a pressure plate arranged in the mounting device housing for mounting an optical voltage sensor, an optical fiber flange arranged on the device housing and used in conjunction with the optical voltage sensor, and a connecting plate for fixing the mounting device housing to the GIS housing flange; the mounting device housing is designed with an opening surface that fits with a pot-type insulator and a GIS housing flange; the optical voltage sensor is crimped and fixed to the bracket by adjusting the fastening screws at both ends of the pressure plate. The present invention fixes the optical voltage sensor on the outer surface of the insulating part of the GIS pot-type insulator by means of the mounting device housing and the connecting plate, and uses the optical voltage sensor to measure the electric field distribution therein, which can not only realize the measurement of the GIS bus voltage, but also realize the installation, disassembly, operation and maintenance of the sensor without affecting the operation of the primary equipment.
