Problems solved by technology

In addition, due to the inevitable friction between structural parts during the installation and transportation of GIS, foreign matter is generated, which has a significant impact on the insulation in GIS
At present, during the operation of EHV / UHV GIS insulators, many flashovers or burst faults have occurred along the surface, and under long-term operation, the insulator metal-epoxy bonding interface peeling off, discharge and other faults have occurred from time to time

Abstract

The invention discloses an ultra / ultra-high voltage GIS / GIL busbar, which comprises a shell, a current-carrying conductor, a high-voltage end conductor and an insulator body, the current-carrying conductor is coaxially arranged The current conductor is coaxially connected, the insulator body includes the insulator resin body and the high-voltage end metal insert and the low-voltage end metal insert respectively installed at both ends of the insulator resin body; the high-voltage end metal insert is connected to the high-voltage end conductor, the axis of the insulator body The axis of the current conductor is vertical, the metal insert at the low-voltage end is connected to the shell, and the axis of the insulator body is set horizontally. The invention can improve the surface insulation performance and mechanical performance of the super / ultra-high voltage GIS insulator, suppress the influence of metal particles in the GIS on the insulation, and ensure the safe and stable operation of the GIS insulator.

Description

Technical field [0001] The present invention belongs to the technical field of power equipment structure design, particularly relates to an ultra / ultra high voltage GIS / GIL busbar. Background [0002] Insulator is the key component of uh-voltage gas insulated metal closed switchgear (Gas Insulated Switchgear, GIS), plays a role in supporting conductor and electrical insulation, long-term operation, it will withstand lightning, operation and other impact voltage and short circuit electrical power, vibration of mechanical stress, its mechanical strength, insulation performance is related to the safety and stability of system operation. In addition, due to the inevitable friction between the structural parts of the GIS during installation, transportation, etc., foreign objects are generated, which has a significant impact on the insulation in the GIS. At present, ultra / ultra-high voltage GIS insulators have a number of flashover or burst faults along the surface during operation...
