Description

Electric connector of micro-water pressure temperature sensor for GIS Technical Field The utility model relates to an electrical connector of a micro-water pressure temperature sensor for gas insulated switchgear, in particular to an electrical connector of a micro-water pressure temperature sensor for GIS. Background SF6 gas has excellent insulation and arc extinguishing performance, is widely applied to electronic and electric equipment, and is typically applied to GIS (gas insulated switchgear) in high-voltage switchgear of power transmission and transformation stations, power plants and the like in power supply departments. SF6 gas is easy to react with insulating materials in high-voltage switch equipment under the action of high-temperature electric arc to generate fault gases such as CO, H2S and the like, and the micro water value (ppmv) refers to the volume of water contained in each million parts of gas per unit volume, so that the micro water is called micro water because of the low water content, and the micro water is applied to places with strict requirements on environmental dryness in industry. In high-voltage switch equipment, the insulation performance of SF6 gas can be reduced due to the fact that the micro water value is too high, and therefore the safety operation of the high-voltage switch is affected. The common micro-water pressure temperature sensor is complex in electrical connector connection, is connected to the aviation plug from the electrical connector, is connected to the metal hose connector again, and is complex in connection and high in cost. Disclosure of utility model In order to solve the defects of the prior art, the utility model provides the electrical connector of the micro-water pressure temperature sensor for the GIS, solves the problems of excessively complex and excessively high cost of the traditional connecting piece, provides the electrical connector with lower cost and simpler, more convenient and safer operation, and can be directly connected with a metal hose connector. The technical scheme is that the electric connector of the micro-water pressure temperature sensor for the GIS comprises a sensor upper cover, a wiring disc, an inserting sheet and a wire harness, wherein one end of the sensor upper cover is provided with a step hole, the wiring disc is arranged on a step surface of the step hole, the inserting sheet is inserted into the wiring disc, one end of the inserting sheet is positioned in the step hole along with the wiring disc, the other end of the inserting sheet is exposed out of the sensor upper cover, the wire harness is connected with the wiring disc and is connected with the inserting sheet, one end of the wire harness is positioned in the step hole along with the wiring disc, the other end of the wire harness is exposed out of the sensor upper cover, the other end of the wire harness is provided with a wire pressing terminal, the wire pressing terminal is provided with a rubber shell, and the step hole is provided with an internal thread metal hose connector. The end part of the inserting sheet is provided with pins, the wiring disc is provided with a plurality of groups of pin hole sites, and the pins are correspondingly welded in the pin hole sites. The outer side of the bottom of the upper cover of the sensor is provided with a groove. Bottom of sensor upper cover the outside is also provided with a sealing groove.
