Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] An embodiment of the present invention with the GIS busbar device of the grounding switch is as Figure 1 to Figure 4 As shown, it is a three-phase shared box GIS busbar device, including a GIS busbar 1 and a grounding switch 7. The GIS busbar 1 includes a busbar barrel 2, a busbar conductor 3 and pot insulators 4 arranged at both ends of the busbar barrel 2. The busbar conductor 3 is provided with three phases, all of which are connected between the pot insulators 4 at both ends; the grounding switch 7 includes a switch housing 8 and an operating mechanism 9, and the side wall of the busbar cylinder 2 is provided with a connecting flange 5. The switch housing 8 is provided with a butt flange 26 adapted to the connecting flange 5 and is fixed on the bus bar barrel 2 through the butt flange 26. The switch housing 8 is a sealed housing, and the sealed housing The inne...

Abstract

The invention relates to a GIS bus device with a grounding switch. The GIS bus device comprises a GIS bus and a grounding switch. The GIS bus comprises a bus cylinder body, a bus conductor and basin-type insulators arranged on two ends of the bus cylinder body. The bus conductor is connected between the basin-type insulators on two ends. The grounding switch comprises a switch housing body fixed to the bus cylinder and a movably arranged moving contact. A grounding switch port through which the moving contact enters the bus cylinder body is arranged in the side wall of the bus cylinder. A static contact corresponding to the moving contact of the grounding switch is arranged on the bus conductor. In this way, the moving contact is capable of directly entering the bus cylinder body to be connected with or separated from the static contact through the grounding switch, arrangement of the bus conductor in the bus cylinder body in the prior art is not affected; there is no need to arrange aswitching structure on the end part of the GIS bus to connect the static contact of the grounding switch with the bus conductor; quantity of parts can be reduced; and the whole size of the GIS deviceis reduced.

Description

technical field [0001] The invention relates to a GIS busbar device with a grounding switch. Background technique [0002] GIS equipment refers to the secondary equipment in a substation other than transformers, including busbars, circuit breakers, isolating switches, grounding switches, etc., which are organically combined through optimized design, sealed by a container, and the inside of the container is filled with sulfur hexafluoride gas for insulation. GIS busbar, isolating switch, and grounding switch are important equipment for transmitting electric energy in GIS equipment, and the safe and reliable operation of GIS busbar is an important guarantee for the smooth transmission of electric energy. Generally, the GIS busbar structure adopts a linear overall structure with a length ranging from a few meters to tens of meters, including the busbar cylinder. The two ends of the busbar cylinder are equipped with pot insulators, and the bus conductors are connected between t...
