Embodiment 1

[0022] see Figure 1-4 , an interchangeable adjustable high-voltage grounding switch, including a disconnector base 8, a disconnector contact seat 7 is arranged on the disconnector base 8, and a vertical grounding switch is fixed on one side of the disconnector contact seat 7. The contact sleeve 6, the grounding switch static contact sleeve 6 is provided with a vertically corresponding grounding switch moving contact sleeve 5, and the upper side wall of the grounding switch moving contact sleeve 5 is provided with a grounding switch static contact sleeve. The clamping mechanism for the clamping of the head sleeve 6, the crank handle 3 is installed on the base 8 of the isolating switch, the crank handle 3 is connected with a driving mechanism, and the base 8 of the isolating switch is vertically fixed with a The guide rod 28 socketed by the moving contact sleeve 5 of the earthing switch is connected with a telescopic mechanism for pushing the moving contact sleeve 5 of the eart...

Embodiment 2

[0029] On the basis of Embodiment 1, in addition, a connection plate 22 is fixed on the side wall of the earthing switch moving contact sleeve 5 of the device, and the connection plate 22 is horizontally pierced with an abutment column 11, and the end of the abutment column 11 The limit plate 21 is fixed, and the limit spring 20 sleeved on the abutment column 11 is fixed between the limit plate 21 and the guide rod 28 . Several arc grooves 19 are equally spaced on the side wall of the guide rod 28 .

[0030] In the process of closing or opening, the static contact sleeve 6 of the earthing switch slides relative to the guide rod 28. At this time, the abutment column 11 abuts and slides against the guide rod 28 under the elastic action of the limit spring 20, And it abuts against the arc groove 19 intermittently, so that in the process of closing and opening, the operator can well grasp the vertical displacement of the moving contact sleeve 5 of the earthing switch, and has good ...

Abstract

The invention discloses an interchangeable adjustable high-voltage grounding switch, which relates to the technical field of power equipment. The interchangeable adjustable high-voltage grounding switch comprises an isolating switch base, a clamping mechanism clamped with a static contact sleeve of the grounding switch is arranged on the upper side wall of the moving contact sleeve of the grounding switch, a hand crank is rotatably mounted on the isolating switch base, and a telescopic mechanism for pushing the moving contact sleeve of the grounding switch to vertically slide is connected ontoa driving mechanism. The hand crank is rotatably arranged to rotate; the telescopic effect of the driving mechanism on the telescopic mechanism is achieved; the telescopic mechanism can drive the grounding switch moving contact sleeve to vertically ascend or descend relative to the guide rod; that is to say, the grounding switch moving contact sleeve can be inserted into the grounding switch static contact sleeve to achieve the switching-on action when moving upwards, the grounding switch moving contact sleeve can move downwards to achieve the switching-off action when being pulled out of thegrounding switch static contact sleeve, the switching-on action and the switching-off action are stable and firm in operation, and the reliability of the switching action of the device is effectivelyimproved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an interchangeable adjustable high-voltage grounding switch. Background technique [0002] The grounding switch refers to a mechanical grounding device that releases the static electricity of the equipment and circuits under maintenance and ensures the personal safety of maintenance personnel during power outage maintenance. It can withstand the current for a certain period of time under abnormal conditions such as short circuit, but it does not pass the load current under normal conditions. It is usually a part of the disconnector. [0003] The patent whose authorized notification number is CN105513849 B discloses a grounding switch, including a frame, a moving contact, a static contact and a driving device for the moving contact, the moving contact and the static contact are arranged in pairs, and it is characterized in that: The moving contact driving device drives...
