Description

Technical Field

[0002] AC33kV GIS switchgear is a gas-insulated, metal-enclosed switchgear used in 33kV AC power systems. During major overhauls or preventative testing of AC33kV GIS switchgear, it is necessary to disassemble and install AC33kV GIS cable terminations. When removing the termination, due to the high friction between the termination and the base, three to four people are required to work together, using considerable force to pull the termination out. This process can easily cause changes in the internal structure of the termination, leading to abnormal internal electric field distribution and insulation abnormalities. It may also directly cause components such as conductive rings to detach from the base, posing a risk of the termination falling and injuring workers. Reinstalling the termination also requires multiple people, and difficulty in proper insertion can cause stripped or damaged mounting screws. Currently, it is necessary to develop a termination disassembly and / or installation device to facilitate the removal and / or installation of the termination. Utility Model Content
