Embodiment Construction

[0011] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0012] figure 2 Indicates the internal structure of the present invention. In this example, the isolating switch housing 19 and the fast earthing switch housing 14 are connected by bolts 8, so that the GR type isolating switch unit and the fast earthing switch unit are organically combined into one unit.

[0013] exist figure 2 Among them, all the functions of the original isolating switch are retained, the static contact 2 of the grounding switch is connected to the center insert on the insulating flange 1 through bolts, the moving contact 5 of the isolating switch is placed on the conductor 4, and the conductor 4 is installed in the pot type insulator 3. Both the static contact 6 of the isolating switch and the fast grounding static contact 9 are placed on the conductor 7 . When the moving contact 5 of the isolating switch is in the middle position, that ...

Abstract

The invention discloses a combination right-angle isolating switch with a rapid ground switch, comprising a right-angle isolating switch part and a rapid ground switch part; the switch is characterized in that: the rapid ground switch part is combined with the right-angle isolating switch part in a same shell through the flange interface at one level side of the isolating switch shell, and connects the fixed contact of the rapid ground switch with a fixed contact of an isolating switch through a conductor; the conductor is vertically arranged on the flanged interface on upper and lower ends of the isolating switch shell. The invention compositely places the rapid ground switch at the side end of the GR type isolating switch shell, thereby enlarging the interface of the GR type isolating switch, so as to cause the connecting mode of the GR type isolating switch to be more flexible, has more plenty and diversified structure arrangement; because a base type insulator is removed, which saves material cost and has cabinet volume.

Description

technical field [0001] The invention relates to a GR type (right-angle type) isolating switch with a quick grounding switch for GIS (gas-insulated metal-enclosed switchgear). Background technique [0002] Generally, the GR-type isolating switch and fast grounding switch for GIS are respectively installed in two metal shells on the left and right, and are separated by an insulating basin, so that the two become independent switching units ( figure 1 ). With such a structure, the GR type disconnector can only use the two flange interfaces on the bottom side and the right side, leaving the other two flange interfaces on the upper side and the left side idle. It is not only bulky and inconvenient to install, but also makes the connection mode of the GR type isolating switch unable to be flexibly arranged (for example, it cannot be turned vertically to connect with other components). Contents of the invention [0003] The purpose of the present invention is to provide a compo...
