[0002] GIS, also known as gas insulated substation. In a gas insulated substation, most of the electrical equipment is directly or indirectly sealed in a pipe tree composed of metal pipes and casings, and no switches, lines, or terminals can be seen from the outside. The interior of the pipe tree uses SF6 gas as the insulating medium, and all high-voltage electrical components are sealed in a grounded metal cylinder. It is a high-voltage power distribution device composed of 7 types of high-voltage electrical appliances: circuit breakers, busbars, disconnectors, voltage transformers, current transformers, lightning arresters, and casings.

Once the moving and static contact conductors are in contact with the inner contour of the internal conductor of GIS during the installation process, they may be bumped and scratched, posing a safety hazard. In addition, the installation efficiency is low and multiple operators are required to perform collaborative installation.

[0004] Therefore, how to quickly install the moving and static contact conductors and effectively avoid the moving and static contact conductors from contacting the inner contour of the conductor inside the GIS during installation is a technical problem that urgently needs to be solved.
