Novel safety isolation device for power distribution operation without power outage

Abstract

The invention relates to a novel safety isolation device for power distribution operation without power failure. The novel safety isolation device comprises a first insulating baffle, a second insulating baffle, a first clip, a second clip, a first hook, a second hook and an insulating rod; when a power grid operation inspector replaces a disconnecting switch, a drop-out fuse and other live-line work, the direction and position of the insulating rod can be controlled by holding the insulating rod at the lower end of the device, and the insulating rod can be conveniently placed on a cross arm by utilizing the rectangular groove in the first insulating baffle plate; in addition, leads of an adjacent-phase electrified body and a surrounding grounding body can be fixed and hung on the first hook and the second hook, so that the risk of short circuit caused by contact of all electrical components is effectively isolated, and the device is simple in structure, convenient to operate, practical in actual work and low in cost.

[0002] When the power grid inspection personnel carry out the distribution line inspection work, the safety distance is an important guarantee to ensure the personal safety of the staff in the distribution network live operation. However, insulation isolation is a weak link in the live operation of 10kV and below power distribution equipment , due to the small air gap of power distribution equipment and the small safety distance of operation, the development of live work in power distribution is limited to a certain extent

The current conventional insulation shielding requires a large number of insulating blankets for shielding. When shielding, attention needs to be paid to the order and the size of the overlapping parts. The operation process is cumbersome, time-consuming and labor-intensive, and the live work takes a long time, which increases the risk during the operation process; Especially for 10kV power equipment that directly supplies power to users, the requirements for power supply reliability are higher; therefore, it is necessary to use safe tools in this link, standardize operating methods, and work safely to improve the safety and reliability of power distribution operations
