Embodiment Construction

[0021] In order to make the technical solution of the present invention clearer, further detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 Shown is a schematic diagram of the system structure of a device for detecting and locating discharge sources of GIL / GIS according to the present invention. The device mainly includes: several vibration sensors S1, detection terminals U1 equal in number to the vibration sensors, and a host computer C1. The working principle of the whole device is as follows: Before the test, a vibration sensor is installed and fixed on the outside of each gas chamber of the equipment under test G1, which is used to detect the signal excited by the discharge inside the shell G1; A detection terminal U1 is installed near each vibration sensor S1, and the detection terminal is fixed on the shell G1 of the equipment under test with a fastening belt, and connected to the vi...

Abstract

The invention discloses a GIL/GIS discharge source detection and positioning apparatus and a method. The apparatus and the method are used to detect and position a discharge fault of a GIL/GIS during a voltage withstanding test or operation. The apparatus comprises vibration sensors fixed to a GIL/GIS shell, detection terminals and an upper computer. The vibration sensors and the detection terminals are arranged in each air chamber of equipment to be detected. When the GIL/GIS generates discharge, each vibration sensor receives a discharge-excited vibration signal. Each detection terminal carries out amplification, filtering and acquisition processing on a discharge signal. The upper computer carries out synchronization on acquisition of each terminal through a wireless network and receives acquisition data so that accurate analysis and positioning to the discharge signal are realized.

Description

technical field [0001] The invention relates to a technology for detecting the insulation state of electric equipment and its application field, in particular to a device and method for detecting and locating a discharge source of a GIL / GIS. Background technique [0002] Gas-insulated metal-enclosed switchgear (GIS) and gas-insulated transmission lines (gas-insulated line, GIL) have the advantages of small footprint, small size, high reliability and simple maintenance, and are widely used in urban In high-voltage power transmission and transformation systems such as power grids, power plants, and large factories and mines. At present, GIS and GIL have become important equipment in the power system, and their own reliability is related to the stable and safe operation of the entire power network. [0003] Some insulation defects are sometimes introduced during the manufacture, on-site installation, commissioning and operation of GIS / GIL. After the equipment is electrified, t...
