Connecting structure of GIS sleeve

Abstract

The invention discloses a connecting structure of a GIS sleeve. The connecting structure comprises a sleeve module and an assembling module. The sleeve module comprises an outgoing line shell and a plurality of sleeve assemblies. Each sleeve assembly comprises a sleeve, a conductive rod, an outgoing line conductor, a conductive seat and a spring contact finger. The sleeve is hermetically connected to the upper end of the outgoing line shell; the conducting rod is arranged in the sleeve; the conductive seat is connected to the upper end of the outgoing line conductor and is movably connected with the lower end of the conductive rod; the spring contact finger is arranged between the conductive seat and the conductive rod; the assembling module comprises an assembling shell and an internal conductor in the assembling shell; the assembling shell is hermetically connected to the lower end of the outgoing line shell, and the lower end of the outgoing line conductor is connected with the internal conductor. Technical prejudice is overcome, usual design thinking in the industry is broken through, an insulator is not arranged between the outgoing line shell and the assembling shell, the outgoing line conductor is used for connecting the conducting rod and the internal conductor, the overall structure is simplified, the product cost is reduced, installation is more convenient, the risk of insulator breakdown is eradicated, and the product reliability and standardization degree are improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment, in particular to a connection structure of a GIS bushing. Background technique [0002] In the existing GIS bushing installation structure, the conductive rod is connected to the pot insulator through the connecting conductor, and then connected to the inner conductor through the bus tie conductor. Among them, the insulator plays the role of solid insulation. [0003] The above-mentioned overall structure is relatively complicated and time-consuming to install; moreover, since the bushing and the conductive rods inside are connected on site, it is inevitable that dust and particles will float in and adhere to the insulator, causing the risk of insulator breakdown; Or, there are many types of internal conductors, such as three-position static end conductors, L-shaped busbars or three-way busbar conductive rods, etc., which have different sizes and different installation positions, ...
