Abstract

The invention relates to the technical field of power system detection, and discloses a portable GIS partial discharge detection device. The portable GIS partial discharge detection device comprises a main box body and an auxiliary box body at one side of the main box body. A detector body is arranged inside the main box body. A first UHF sensor and a second UHF sensor are arranged inside the auxiliary box body and are electrically connected with the detector body. The detector body comprises microprocessor, a control circuit board in electric connection with the microprocessor, and a display unit and an input unit which are electrically connected with the microprocessor. The control circuit board comprises a UHF sensor acquisition circuit, a UHF signal processing circuit and a power processing circuit. The invention has the beneficial effects that good anti-interference performance is realized by arranging the two UHF sensors so that the detection sensitivity is improved; in addition, the structure is simple, the cost is low and the installation is convenient.

Description

technical field [0001] The invention relates to the technical field of power system detection, in particular to a portable GIS partial discharge detection device. Background technique [0002] The full name of GIS is Gas Insulated Combined Electrical Appliance, which is an important equipment in the power system. GIS optimizes and designs all primary equipment in a substation except transformers into an organically combined whole, generally a building block structure. Generally speaking, it is composed of circuit breaker, isolating switch, grounding switch, voltage transformer, current transformer, lightning arrester, busbar and bushing. It has the following characteristics: (1) small structure; (2) reliability (3) good safety; (4) can prevent adverse external influence; (5) short installation period; (6) easy maintenance. [0003] After the GIS is installed on site, it is necessary to conduct a pressure test to verify whether it is damaged during transportation and instal...
