Problems solved by technology

[0003] In the existing technology, due to the difficulties in handling power outages and work permit procedures for street lamp substations and other user-owned equipment, such as failure to find or cooperate with the user's electrician, the line maintenance work cannot be carried out as planned
If it is carried out according to low-voltage live work, it cannot meet the requirements of safety regulations, and it is easy to cause safety hazards such as electric shock to the staff

Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0018] Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a protection device for live lines. The live line includes wires for transmitting electric energy and insulators for fixing the wires. The protection device of this embodiment includes a first insulating sheath 1 and a second Insulation sheath2.

[0019] Wherein, the first insulating sheath 1 includes a cover body 11 for accommodating an insulator. The housing 11 includes a closed bottom surface, an insulator inlet opposite to the bottom surface, and a side wall arranged between the bottom surface and the insulator inlet. The side wall is provided with a wire side outlet extending through it in...

Abstract

The invention provides a protecting device for an alive circuit and an insulating protection method. The alive circuit comprises a lead used for transmitting electric energy and an insulator used for fixing the lead. The protecting device comprises a first insulating sheath and a second insulating sheath, wherein the first insulating sheath comprises a shield used for accommodating the insulator, the shield comprises a bottom surface, an insulator inlet opposite to the bottom surface and a side wall arranged between the bottom surface and the insulator inlet, the side wall is provided with a longitudinally through lead side outlet, the second insulating sheath comprises a pipe used for accommodating the lead, the pipe is provided with a first peripheral fracture, and one end of the second insulting sheath is connected with the lead side outlet of the first insulating sheath. By the adoption of the technical scheme, live working is facilitated for workers, and the personal safety of the workers is guaranteed.

Description

technical field [0001] The invention relates to the field of electric equipment maintenance, and more specifically, to a protection device and an insulation protection method for live lines. Background technique [0002] During the new installation, relocation and maintenance of low-voltage user ammeters and the operation and maintenance of low-voltage lines, some working environments have the situation that low-voltage lines and street lamp lines are erected on the same pole. According to the requirements of the "Low-Voltage Electricity Safety Regulations", "operators are not allowed to cross when the low-voltage live wires are not insulated." [0003] In the prior art, due to difficulties in handling power outages and work permit procedures for street lamp substations and other user-owned equipment, such as failure to find or cooperate with user electricians, line maintenance work cannot be carried out as planned. If it is carried out according to low-voltage live work, i...
