Lightning arrester interval safety protection device and method

Abstract

The invention provides a lightning arrester interval safety protection device, and the device comprises a switch cabinet and an insulating baffle connected with the switch cabinet, wherein one side ofthe insulating baffle is hinged to a cabinet body of the switch cabinet, and the other side of the insulating baffle is a free end. A groove with a set track is formed in the insulating baffle, a guide structure is contained in the groove, and the guide structure is connected with a lightning arrester handcart. Therefore, the technical problem that a static contact in a bus interval is always electrified when connected to an electrified 10kV bus, so maintainers mistakenly enter the electrified interval to clean equipment in a cabinet to cause an electric shock accident is solved, when a handcart is pulled out, an insulating baffle freely falls off and is closed under the action of gravity, the static contact is isolated, and in order to prevent opening, the manual or electric control locking can be adopted.

Description

technical field [0001] The present disclosure relates to a lightning arrester interval safety protection device and method. Background technique [0002] At present, most of the 10kV switch cabinets used by most power companies are central cabinets, which are fully sealed equipment, and the busbar interval and outlet interval are not used, because the double-contact knife switch is not used to isolate and seal the live busbar and the lightning arrester. The exposed static contact is still charged after the arrester handcart is pulled out. [0003] When carrying out the maintenance test of the busbar arrester, the cabinet door needs to be opened, because the static contact in the busbar compartment is always connected to the live 10kV busbar, and the maintenance personnel are mixed with the handcart switch of the line outlet, resulting in " The false image that the handcart has been pulled out and there is no electricity in the cabinet can easily cause maintenance personnel ...

Problems solved by technology

[0002] At present, most of the 10kV switch cabinets used by most power companies are central cabinets, which are fully sealed equipment, and the busbar interval and outlet interval are not used, because the double-contact knife switch is not used to isolate and seal the live busbar and the lightning arrester. Contact, resulting in the arrester trolley pulled out, the exposed static contact is still charged

[0003] When carrying out the maintenance test of the busbar arrester, the cabinet door needs to be opened, because the static contact in the busbar compartment is always connected to the live 10kV busbar, and the maintenance personnel are mixed with the handcart switch of the line outlet, resulting in " The false image that the handcart has been pulled out and there is no electricity in the cabinet can easily cause maintenance personnel to mistakenly enter the charged interval to clean the equipment in the cabinet and cause electric shock accidents. This kind of installation violation seriously threatens the personal safety of employees and has constituted a major safety hazard.
