Description

Technical Field

[0001] This utility model relates to the field of GIS busbar technology, specifically to a GIS busbar conductive rod docking fixture. Background Technology

[0002] GIS (Gas Insulated Switchgear) systems are widely used in power systems due to their miniaturization, high reliability, and short installation cycle. GIS systems are typically installed in sections, based on a busbar. During installation, the outermost bay is used as the first installation bay. After the first bay is in place, the cover on the side connecting to the second bay of the busbar drum is opened, and a conductive rod is inserted to connect the adjacent bays. The key to this process is to first connect the conductive rod to the staggered contact of the busbar drum (this contact belongs to the first bay), and then connect the other end of the conductive rod to the staggered contact of the next bay. In actual operation, the conductive rod is prone to "head-down" under gravity. Currently, manual lifting or using tooling supports inside the drum is commonly used to ensure the connection of the conductive rod, but these methods cannot guarantee the centering of the conductive rod, posing a risk of damage to the conductive rod and its support. Furthermore, these techniques require construction personnel or tooling to enter the busbar drum, resulting in secondary human-caused contamination and excessive resistance. The limited internal space of the busbar drum also makes the connection of the conductive rod difficult. Therefore, designing a GIS busbar conductive rod docking fixture is of great significance.
