Problems solved by technology

However, if the area of ​​the shutter is large, the occupied space of the shutter will be increased, which will cause inconvenience to other operations on the front panel. Furthermore, if the area of ​​the shutter is large, it will easily protrude from the edge of the front panel, affecting the entire solid insulating ring. The network cabinet is beautiful, but at the same time it brings the risk of bumps to the operator

Embodiment Construction

[0027] The present invention will be further elaborated below by means of the accompanying drawings and examples.

[0028] Such as figure 1 , figure 2 and image 3Shown: a solid insulated ring network cabinet, including a cabinet body, the cabinet body includes a bottom plate 1, a top plate, a side plate 2, a front plate 25 and a rear plate, and the side plates include a left side plate and a right side plate. In this embodiment, Said side plate specifically refers to the right side plate. In order to clearly show the structure inside the cabinet, the top panel, rear panel and left panel are removed from the diagram. There is a grounding switch mechanism in the cabinet, and the grounding switch mechanism includes a static contact seat 3, a moving contact 4, a crank arm 6, a crank arm 2 7, a crank arm 3 8 and a return spring assembly 9, and the moving contact 4 is A moving contact fixing seat 5 is provided. The moving contact 4 is inserted into the static contact seat 3 t...

Abstract

The invention discloses a solid insulation ring main unit. The solid insulation ring main unit comprises a unit body, the unit body comprises a bottom plate, a side plate and a front plate, and a grounding switch mechanism is arranged in the unit body. The grounding switch mechanism comprises static contact bases, moving contacts, a first connecting lever, a second connecting lever, a third connecting lever and a first reset spring assembly. A moving contact fixing base is arranged on the moving contacts, A T-type installation frame is arranged on the bottom plate and composed of a longitudinal supporting part and a transverse installing part. One end of the transverse installing part is connected with a grounding operation shaft in a rotatable mode, and one end of the first connecting lever and one end of the second connecting lever are fixed to the grounding operation shaft. The included angle formed between the first connecting lever and the bottom plate and the included angle formed between the second connecting lever and the bottom plate are identical. The other end of the first connecting lever is hinged to one end of the first reset spring assembly. The other end of the first reset spring assembly is connected with the side plate, the first connecting lever and the first reset spring assembly are not on the same straight line, one end of the third connecting lever is hinged to the other end of the transverse installing part, the other end of the third connecting lever is connected with the moving contact fixing base, and the other end of the second connecting lever is connected with a body of the third connecting lever.

Description

technical field [0001] The invention relates to the field of complete switch cabinets for power transmission and distribution, in particular to a solid insulated ring network cabinet. Background technique [0002] The solid insulated ring network cabinet is an emerging smart grid power distribution equipment, and the grounding switch mechanism is the main component of the solid insulated ring network cabinet. The grounding switch mechanism is used to control the opening and closing of the grounding switch. The grounding switch mechanism inside the solid insulated ring main unit of the prior art mainly adopts an oil-immersed switch, which drives the moving contact through a single crank arm, but the large displacement cannot be achieved through a single crank arm, and only transformer oil can be added to reduce the size of the grounding switch. At the same time, it is necessary to apply a large force to realize the opening and closing of the grounding switch, which is inconv...
