A test casing for gis terminal test device

Abstract

The invention provides a test bushing for a GIS terminal test device, which is used for testing a GIS terminal; the bushing includes an insulating cylinder, a high-voltage introduction mechanism, a grounding shielding electrode and a grounding flange; the grounding flange and the insulating One end of the cylinder is connected, and the high-voltage introduction mechanism is connected to the other end of the insulating cylinder; the ground shielding electrode is arranged on the inner wall of the insulating cylinder and connected to the grounding flange; the end of the insulating cylinder connected to the grounding flange The other end facing the insulating cylinder is provided with a test cavity for the GIS terminal to protrude into. During operation, the test cavity forms a sealed test cavity. The bushing is safe and reliable, small in shape, simple in structure, and easy to install and use. It can carry out the completion pressure test of GIS terminals and cable lines, can effectively improve the accuracy, effectiveness and reliability of the test, and is conducive to widespread popularization and promotion.

Description

technical field [0001] The invention relates to the technical field of electric equipment, more specifically, to a test sleeve used for a high-voltage cable GIS terminal test device. Background technique [0002] With the continuous development of the electric power industry and the application of high technology, the design and production level of gas insulated switches has been continuously improved, and the switch stations in modern urban areas have gradually developed into miniaturization and intelligence. According to the requirements of the national standard and IEC60840, the completion acceptance test is required after the cable system is installed to effectively ensure the safe and stable operation of the power system. [0003] For the cable lines with GIS terminals at both ends, although the test device for the electrical test of the cable loop has been developed at home and abroad, and has become a commodity, but the safety distance of the space around the GIS term...

Problems solved by technology

[0003] For the cable lines with GIS terminals at both ends, although the test device for the electrical test of the cable loop has been developed at home and abroad, and has become a commodity, but the safety distance of the space around the GIS terminal in many switch stations in China is very small. However, due to the shortcomings of the existing GIS terminal test device, such as complex structure, large size, complex assembly, inflexible assembly position, and limited use in many occasions, the purpose of rapid test cannot be achieved, thereby increasing the difficulty of cable construction.

It can be seen that the existing test equipment has been unable to meet the needs of the field test
