Abstract

The invention relates to an ultra high voltage AC gas mixture GIL (gas-insulated metal enclosed transmission line) segment partial discharge signal measurement method. The structure of the ultra highvoltage AC gas mixture GIL live check segment is used, partial discharge signal acquisition is carried out according to each gas chamber, the acquired partial discharge signals are recorded and analyzed, and the state of the ultra high voltage gas mixture GIL is judged. Whether an insulation defect happens to the ultra high voltage GIL during an operation process can be checked, and the operationreliability of the ultra high voltage AC GIL can be effectively improved.

Description

technical field [0001] The invention relates to the field of electric power transmission, in particular to a method for measuring a partial discharge signal of a UHV AC mixed gas GIL line section. Background technique [0002] GIL (gas-insulated metal enclosed transmission line) is the abbreviation of gas-insulated metal enclosed AC mixed gas transmission line. 6 Or other insulating gas, high-voltage, high-current, and long-distance power transmission equipment coaxially arranged between the shell and the conductor, with large transmission capacity, small footprint, flexible layout, high reliability, small maintenance, long life, and low environmental impact Small significant pluses. At present, the high-voltage GIL technology is basically mastered by several large European and American companies such as ABB, Siemens, and AZZ in the United States. Their latest GIL products have realized component standardization and modular design, and can be elastically bent along the path...
