Abstract

The invention discloses a two-way isolation switch and a GIS switchgear of using the same. The two-way isolation switch comprises a barrel, wherein the barrel comprises a shell and a telescopic joint; the shell and the telescopic joint are coaxially arranged at the rear side of the shell; a conductive rod assembly is arranged in the barrel and comprises a front moving contact block and a front moving contact; the front moving contact is arranged at the front end of the moving contact block in a guide motion manner; the conductive rod assembly comprises a rear moving contact block located at the rear side of the front moving contact block and a rear moving contact; the rear moving contact is arranged at the rear end of the rear moving contact block in a guide motion manner; the front side of the shell is connected with a first basin-type insulator; the rear side of the telescopic joint is connected with a second basin-type insulator; the first basin-type insulator is provided with a front fixed contact; and the second basin-type insulator is provided with a rear fixed contact. The two-way isolation switch is used for the GIS, so that the target of two-way isolation can be achieved, the two-way isolation switch can play a role in being dismantled from the position to maintain the GIS, a transition barrel in the prior art is replaced with the isolation switch and the two-way isolation switch is convenient to dismantle.

Description

technical field [0001] The invention relates to a bidirectional isolating switch and a GIS switchgear using the bidirectional isolating switch. Background technique [0002] With the rapid development of the industrial field, the scale of the power grid is becoming larger and larger, and the voltage level is also increasing. Gas-insulated metal-enclosed switchgear (GIS) is more and more widely used in substations due to its advantages such as being less affected by the external environment, saving land, and not requiring frequent maintenance. [0003] In the actual operation of the substation, the GIS equipment is composed of multiple compartments, and the conductive connections between the compartments are realized through connecting busbars. The connecting busbar includes a cylinder extending in the front and rear directions, insulators arranged at the front and rear ends of the cylinder, and a conductive rod assembly coaxially inserted in the cylinder. The center conduc...
