Description
Technical Field

Metal enclosed switchgear (such as KYN61) is an indispensable special equipment in a power distribution system, is widely applied to industries such as power plants, petroleum and metallurgy, and is used for power transformation and distribution. Among them, the safety gap is one of important indexes for evaluating the gas insulated metal-enclosed switchgear. The conventional 35kV metal enclosed switchgear has a safety pitch of 300mm, for example, a 35kV switchgear. However, many switch cabinets have small cabinet width and size, and the safety space inside the switch cabinets cannot meet the standard requirements, so that interphase or relative short-circuit accidents are easy to happen. Aiming at the condition that the safety spacing can not meet the requirement, manufacturers adopt an alternative mode of additionally arranging insulating partition plates to enhance insulation, and the problem of interphase short circuit is reduced to a certain extent. Under the condensation condition, the surface resistance of the insulating partition board is sharply reduced, the distribution voltage is also reduced, the air gap distribution voltage is increased, discharge is generated, and the relative or interphase flashover breakdown is gradually developed.
In order to solve the above problems, the patent document of the chinese patent application with application publication No. CN111193217A discloses a vertical copper bar metal-enclosed high voltage switch device, which includes a switch cabinet, wherein a lower contact box in the switch cabinet is electrically connected with a current transformer through a vertically arranged copper bar to increase the phase distance between the lower contact box and the current transformer, and the current transformer is electrically connected with a grounding switch through a vertically arranged connecting copper bar to increase the ground distance between the current transformer and the ground, so that the safety distance between the phases and the ground in the switch cabinet can meet the requirements.

However, in the prior art, the fixed contact terminal in the common contact box and the incoming line terminal of the current transformer are mostly arranged horizontally, and the vertically arranged connecting copper bar cannot be connected with the fixed contact terminal and the incoming line terminal. Therefore, a corresponding conductive connection structure needs to be designed, so that the safety space requirement of the contact box and the current transformer is met under the condition that the vertically arranged connection copper bar is suitable for the common contact box and the current transformer.
