Embodiment Construction

[0045] The specific implementation of the GIS equipment and its fast grounding switch in the present invention will now be described in conjunction with the accompanying drawings.

[0046] A kind of embodiment of GIS equipment among the present invention: GIS equipment comprises fast earthing switch and the output device that drives the input crank arm rotation in the fast earthing switch, such as Figure 4 As shown, the quick grounding switch includes a housing 40, and the up-down and left-right directions are defined by the direction shown in the figure. A contact finger seat 30 is installed at the upper opening of the housing 40, and a finger seat 30 is equipped with a guide that moves along the up and down direction. The inner wall of the movable contact 10 and the contact finger seat 30 is embedded with a contact finger 31 to realize the electrical connection between the movable contact 10 and the contact finger seat 30 and a guide sleeve 32 for guiding the movement of the...

Abstract

The invention relates to the technical field of high-voltage switchgear and provides a high-speed grounding switch and a GIS device to solve the problem in the prior art that the installation error ofthe high-speed grounding switch causes wear and failure. The high-speed grounding switch comprises a housing, a movable contact and a rotary connecting member, wherein the rotary connecting member has a movable contact connecting end connected with the movable contact, a guiding end adaptive to a guiding structure on the housing; the movable contact connecting end of the rotary connecting memberis hinged to a slide block, the movable contact is correspondingly provided with a matching sliding slot for assembling the slide block in a guided manner, the guiding direction of the slide block issimultaneously perpendicular to the guiding direction of the movable contact and the axis of rotation of an input crank; or the movable contact connecting end of the rotary connecting member is hingedto a rotating body, the rotating body is provided with a sliding slot, the movable contact is correspondingly provided with a matching slide block in guiding fitting the sliding slot, and the guidingdirections of the matching slide block and the sliding slot are simultaneously perpendicular to the guiding direction of the movable contact and the axis of rotation of the input crank.

Description

technical field [0001] The invention relates to the technical field of high-voltage switchgear, in particular to a fast grounding switch and GIS equipment. Background technique [0002] The fast grounding switch is an important module on the GIS equipment. It has a certain closing short-circuit current capability and can realize the fast grounding of the bus bar or cable. The inductive current generated by magnetic induction; the second is that when creepage occurs on the insulator inside the shell or arcing occurs inside the shell, the fast grounding switch quickly grounds the main circuit, and the fault current is cut off by the circuit breaker to ensure the safety of the equipment and the power system. [0003] For example, a quick earthing switch disclosed in a patent document with the authorization announcement number CN203367054U and the authorization announcement date of 2013.12. Swivel connector. One end of the rotary connector is connected in a groove of the cross...
