Abstract

The invention discloses a partial-discharge sensor safety detection circuit, which comprises a wireless transceiving circuit (a), a 555 timing detection circuit (b), a display and key unit (c) and an interface circuit (d), wherein the wireless transceiving circuit (a), the display and key unit (c) and the interface circuit (d) are each connected with the 555 timing detection circuit (b). According to the partial-discharge sensor safety detection circuit and a partial-discharge sensor safety detection method, the detection on safety issues of built-in sensors can be achieved through a safety detection device, and the detection result is sent to a data processing server side in a wireless manner, thereby avoiding harm to testing equipment and personnel safety caused by the safety issues.

Description

technical field [0001] The invention relates to the field of partial discharge data management, in particular to a partial discharge sensor safety detection circuit and method. Background technique [0002] GIS is an important equipment commonly used in power systems. When there is insulation defect in the GIS, partial discharge will occur. The detection of partial discharge can effectively determine the insulation state of switchgear. Effective detection of partial discharge is of great importance to ensure the safe and stable operation of GIS important meaning. [0003] Among the current detection methods of partial discharge signals in GIS, the ultra-high frequency method is a practical and feasible method to realize the on-line monitoring of partial discharge in GIS. The ultra-high frequency method uses the sensor to receive the electromagnetic wave from 300MHz to 3GHz excited by the partial discharge to monitor the partial discharge, so the built-in ultra-high frequenc...
