Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Embodiments of the present invention provide a large current grounding device, see Figure 1-Figure 8 , a large current grounding device, including a base 1, a static side base 2, a transmission mechanism, a ground knife 3, a contact finger seat 4 and a contact finger 5.

[0029] The base 1 is a box without a cover on the top; the ground knife 3 is a hollow cylinder, which ensures strength and reduces weight, which is convenient for operation. A positioning structure 13 is provided on the static side base 2, and the positioning structure includes a cylindrical protrusion, which can go deep ...

Abstract

The invention relates to the technical field of high-voltage electrical equipment grounding switches,in particular to a large-current grounding device. The invention solves the problem that the current flow capacity of the existing grounding switch is in contradiction with the installation space. The large-current grounding device comprises a base and a static-side base,and also comprises a transmission mechanism,an earthing knife-switch,a button contact seat and a button contact; the transmission mechanism is arranged in the base,the transmission mechanism drives the earthing knife-switch tomove up and down and rotate,the bottom end of the earthing knife-switch is connected with the base through a soft connection,the button contact seat is fixed on the static side base,the button contactis arranged in the button contact seat,and the button contact seat corresponds to the other end of the earthing knife-switch,when the earthing knife-switch is moved to the highest position,the earthing knife-switch is in contact with the button contact in the button contact seat.

Description

technical field [0001] The present invention relates to the technical field of grounding switches for high-voltage electrical appliances, in particular to large-current grounding devices. Background technique [0002] The grounding switch of high-voltage electrical appliances is a mechanical switch used for the grounding part of the circuit. It not only needs to carry the current under abnormal conditions within a certain period of time, but also needs to be able to withstand a certain insulation voltage. Existing grounding switches include knife-type and direct-acting plug-in types. The installation of the knife-gate-type grounding switch requires a small space, but the current flow capacity is weak. The direct-acting plug-in type grounding switch can withstand large currents, but the installation space huge demand. Contents of the invention [0003] In order to solve the problem existing in the prior art that the current capacity of the grounding switch is inconsistent ...
