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 fast grounding switch and GIS equipment, which can solve the problem of wear and failure of the fast grounding switch in the prior art due to installation errors. The fast grounding switch includes a housing, a movable contact and a rotary connector. The rotary connector has a movable contact connection end connected with the movable contact, and a guide end adapted to the guide structure on the housing; the movable contact of the rotary connector The connecting end of the head is hinged with a slider, and the moving contact is correspondingly provided with an adapter chute for guiding and assembling the slider, and the guiding direction of the slider is perpendicular to the guiding direction of the moving contact and the rotation axis of the input crank arm at the same time; or, The connecting end of the moving contact of the rotary connector is hinged with a rotating body, the rotating body is provided with a chute, and the moving contact is correspondingly provided with an adapter slider that cooperates with the guide of the chute, and the guide of the adapter slider and the chute cooperates The direction is perpendicular to the guiding direction of the moving contact and the rotation axis of the input crank arm at the same time.

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...
