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.

Embodiment 1

[0023] Such as figure 1 As shown, a lightning arrester interval safety protection device includes: a switchgear, an insulating baffle connected to the switchgear, one side of the insulating baffle is hinged with the cabinet body of the switchgear, and the other side is a free end; the insulating baffle There is a groove on the board for setting the trajectory, and the groove is used to accommodate the guide structure, and the guide structure is connected with the lightning arrester handcart.

[0024] Further, a switch lock is arranged on the insulating baffle, and the insulating baffle and the switch cabinet are in a locked state through the switch lock; further, the switch lock is a stainless steel bolt or an electric switch lock, and the electric switch lock includes a power lock, Combination lock or electric lock, multifunctional industrial electric lock BD-D81 can be used.

[0025] Further, one side of the insulating baffle is hinged to the upper edge of the switch cabine...

Embodiment 2

[0033] A lightning arrester interval safety protection device, comprising: a switchgear, an insulating baffle connected to the switchgear, one side of the insulating baffle is hinged to the cabinet body of the switchgear, and the other side is a free end; the insulating baffle has A groove for setting the trajectory, the groove is used to accommodate the guide structure, and the guide structure is connected with the arrester handcart.

[0034] The main insulating baffle includes a fixed insulating baffle fixed on the cabinet body. The fixed insulating baffle is provided with an upper opening and a lower opening. The outer sides of the upper opening and the lower opening are respectively provided with an upper movable insulating The baffle plate and the lower movable insulating baffle matched with the lower opening, the upper movable insulating baffle and the lower movable insulating baffle are connected with a lifting mechanism.

[0035] Preferably, the above-mentioned lifting...

Embodiment 3

[0038] A method for using a lightning arrester interval safety protection device, comprising:

[0039] Match the guide device of the arrester trolley with the groove on the insulating baffle;

[0040] Push the lightning arrester handcart along the direction of the track of the groove, and the insulation baffle is turned upwards to open;

[0041] When the arrester trolley is pulled out along the direction of the track of the groove, the insulating baffle will fall and close freely under the action of gravity, realizing the isolation of charged static contacts.

[0042] In order to prevent opening, by closing the switch lock on the insulating baffle, the purpose of better isolating charged static contacts is achieved.

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 ...
