Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for GIS equipment testing, and specifically to an insulating support fixture for GIS pressure resistance. Background Technology

[0002] During the factory partial discharge test of GIS equipment, the high-voltage generator is connected to the test sample terminals via a copper conductor with an outer aluminum foil tube. In this process, the outer aluminum foil tube serves to even out and shield the electric field. The location of the high-voltage generator is fixed, but the test equipment often varies significantly, some very close to the generator and others very far away. To accommodate test samples in various locations, the copper conductor and aluminum foil tube are often made quite long. When the test sample is close, the aluminum foil tube hangs at a large angle. Due to the varying locations of the test samples, the hanging angle of the conductor varies. When the angle is too large, the conductor is too close to the ground, posing a certain safety hazard.
