Test sleeve for GIS terminal test device

Abstract

The invention provides a test sleeve for a GIS terminal test device, and aims at testing a GIS terminal. The sleeve comprises an insulation barrel body, a high pressure import mechanism, a grounding shielding electrode and a grounding flange; the grounding flange is connected with one end of the insulating barrel body; the high pressure import mechanism is connected with the other end of the insulating barrel body; the ground shielding electrode is arranged on the inner wall of the insulating barrel body and connected with the grounding flange; a testing cavity in which the GIS terminal extends is formed in one end of the insulating barrel body, connected with the grounding flange and toward the other end of the insulating barrel; when in work, the testing cavity forms a closed testing cavity. The sleeve is safe, reliable, small in size, simple in structure, and convenient to mount and use; the completion pressure test can be carried out for the GIS terminal and a cable circuit; the accuracy, efficiency and reliability of test can be effectively improved; the test sleeve is suitable for wide popularization and application.

Description

Technical field [0001] The invention relates to the technical field of power equipment, and 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 power industry and the application of high-tech, the design and production level of gas insulated switchgear has been continuously improved, and switch stations in modern urban areas have gradually developed into miniaturization and intelligence. According to the requirements of the national standard and IEC60840, the cable system needs to be completed acceptance test after installation to effectively ensure the safe and stable operation of the power system. [0003] For cable lines with GIS terminals at both ends, although test devices for electrical testing of cable circuits have been developed at home and abroad, and have become commercial products, the safety distance around the GIS terminals in many domestic switchyards is very ...

AI Technical Summary

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
