Abstract

A grounding switch belongs to the field of grounding switches of KYN61-40.5 high-voltage switch cabinets. The grounding switch comprises a base and high-voltage insulators, wherein brackets are arranged on the base, the high-voltage insulators are arranged in a direction forming a right angle with the brackets, and static contacts are arranged on the top ends of the high-voltage insulators. The grounding switch is characterized in that moving contacts are fixed on the brackets through a rotating shaft, the top ends of the moving contacts are matched with the static contacts, the moving contacts are connected with the brackets through springs, the brackets are 150-180mm high, and the base is 700-800mm long. By shortening the height of the brackets and the length of the base, the installation size is reduced, the movement stroke of the moving contacts is reduced, and the force borne by the springs is reduced. The grounding switch is compact in structure and convenient to operate.

Description

Earthed switch
Technical field
The utility model provides a kind of earthed switch, belongs to the earthed switch field of KYN61-40.5 high-tension switch cabinet.
Background technology
At present, joining the general structure of JN22-40.5 earthed switch in the KYN61-40.5 switch cubicle is: fix row's high-tension insulator along base bottom, each insulator other end is installed a fixed contact, at the base middle part rotating shaft is installed laterally, along rotating shaft laterally corresponding to the insulator position, fixedly mount several moving contacts, moving contact rotates with rotating shaft and does on the arc, lower swing, when being rocked to horizontal level downwards, its end just in time coincide with fixed contact and contacts rotating shaft two, be connected with base with spring by joint, when separating brake, arrange in the moving contact clockwise direction, compress spring simultaneously; When needs closed a floodgate, spring released energy, and accelerated to make moving contact press to following fixed contact counterclockwise, and dynamic/static contact coincide to contact and puts in place, and is reliable and stable, and assembling easily.
The deficiency of its existence is that volume is big, and the very trouble that wastes time and energy is installed.Least allowing customer satisfaction system is when operation, and deciliter earthed switch action required power is very big, and operational stroke is big, and general woman all can not operate.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: a kind of small and exquisite, easy to operate earthed switch of structure that overcomes problems such as existing earthed switch volume is big, installation is wasted time and energy, operating physical force is big is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of earthed switch, comprise base and high-tension insulator, support is set on the base, with the rectangular direction of support high-tension insulator is being set, the high-tension insulator top arranges fixed contact, it is characterized in that: on the support by the fixing moving contact of rotating shaft, moving contact top and fixed contact adapt, the moving contact middle part connects support by spring, and described support height is 150mm-180mm, and base length is 700mm-800mm.
By the height of shortening support and the length of base, reduce installation dimension, the action of moving contact forms and reduces, and spring stress reduces, and is convenient to operation, has overcome problems such as existing earthed switch volume is big, installation is wasted time and energy, operating physical force is big.
Wherein preferred version is:
Described base length is 724mm.Be convenient to install and maintenance.
The center line of described rotating shaft and high-tension insulator absolute altitude are 120mm.Reduce rotational travel.
Compared with prior art, the beneficial effect that this earthed switch has is: on the support by the fixing moving contact of rotating shaft, moving contact top and fixed contact adapt, the moving contact middle part connects support by spring, described support height is 150mm-180mm, and base length is 700mm-800mm, preferred 724mm, the center line of rotating shaft and high-tension insulator absolute altitude are 120mm, reduce rotational travel.By the height of shortening support and the length of base, reduce installation dimension, the actuating length of moving contact reduces, and spring stress reduces.Little, in light weight, the flexible operation, easy for installation of the utility model earthed switch volume has been saved manpower, and price is also relatively cheap, has reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the right side view of Fig. 1;
Wherein, 1, spring 2, support 3, rotating shaft 4, fixed contact 5, base 6, high-tension insulator 7, moving contact.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment 1:
As shown in Figure 1, support 2 is set on the base 5, at the base 5 with the rectangular direction of support 2 high-tension insulator 6 is set, high-tension insulator 6 tops arrange fixed contact 4.By the fixing moving contact 7 of rotating shaft 3, moving contact 7 tops and fixed contact 4 adapt on the support 2, and moving contact 7 connects the top of support 2 by spring 1.
Support 2 highly is 150mm-180mm, and base 5 length are 700mm-800mm, and preferred length is 724mm.Be convenient to install and maintenance.
The center line of rotating shaft 3 and high-tension insulator 6 absolute altitude are 120mm.Reduce rotational travel.
Operation principle or use
Moving contact 7 rotates with rotating shaft 3 and rotates up and down as arc, and when being rocked to horizontal level downwards, its end just in time coincide with fixed contact 4 and contacts.By the height of shortening support 2 and the length of base 5, reduce installation dimension, the action of moving contact 4 forms and reduces, and spring 1 stressed reducing is convenient to operation, overcome problems such as existing earthed switch volume is big, installation is wasted time and energy, operating physical force is big.
