Abstract

The invention relates to an ultrahigh-voltage oil-SF6 sleeve test device which overcomes the shortcomings and defects of single test ability, low test voltage grade and vertical arrangement of sleeve samples of the existing oil-SF6 sleeve test device. The device comprises a test oil tank, a GIS (Gas Insulated Switchgear) bus tube, a GIS sleeve, an oil-SF6 sleeve, an oil conservator, a transition plate, a support base and accessories, and is characterized in that: the oil-SF6 sleeve sample is horizontally mounted. The insulating property of the device can meet the insulation requirement of the sleeve test device with a grade between 500KV and 1,100KV; the actual operation conditions of the oil-SF6 sleeve can be simulated; the sleeve mounting height of the whole test device is reduced, thereby being favorable for the transportation and disassembly / assembly; and meanwhile, the requirements for the structural strength and safety of the test device are reduced, and the requirement for the height of the hall building of the test environment is reduced.

Description

technical field [0001] The invention relates to an ultra-high pressure oil—SF 6 Bushing test device, specifically 1100kV and below voltage grade oil—SF 6 The invention relates to a test device for bushing insulation and temperature rise, which belongs to the technical field of high voltage test in electric power industry. Background technique [0002] For power transmission and transformation equipment with a voltage level of 500kV and above, oil—SF 6 The bushing is a device that directly connects the transformer in the substation of the power transmission and transformation project with the gas-insulated combined electrical appliance. Broad application prospects. Oil—SF 6 When new products are appraised and shipped out, high-voltage bushings need to be type tested or tested one by one. Generally, they should include high-voltage insulation and temperature rise tests. According to the national bushing standards, the bushings should simulate the actual operation as much a...
