Abstract
The invention discloses a kind of high voltage load switch binding post insulating protective cover, comprise, main body and plate; Main body is Baltimore groove, and in main body, interval is welded with baffle plate, and the both sides, lower end of main body are formed with slideway; Inserting board enters in the slideway of main body, closes the bottom of main body.Beneficial effect is: owing to employing the insulating protective cover that dielectric strength is the rated voltage of 4.5 times; effectively by the binding post of high voltage load switch insulation isolation; ensure that live line working personnel and the safe distance facing phase terminal and earth electrode; this protective cover reaches the regulatory requirements of preventive trial; meet the requirement of live line working specialty, thus ensure that the life security of operating personnel.
Description
Technical field
The present invention relates to high-voltage hot-line work field; Particularly relate to a kind of high voltage load switch binding post insulating protective cover.
Background technology
10kV high voltage load switch is the most frequently used a kind of electric equipment of the outlet of 10kV overhead transmission line, branch, contact, it when cutting off circuit with drawing when load, can all play very important effect in the process of overhead transmission line operation, maintenance, changing mode.But due to reasons such as high voltage load switch self character, equipment life and line load changes, usually need to overhaul original high voltage load switch or change.Along with the requirement of society to Reliability of Power Supplying Net Work is more and more higher, once 10kV high voltage load switch needs maintenance and exchanges, the general live line working mode that adopts as far as possible carries out overhauling and changing, this adds the risk of the personal injury of operating personnel to a certain extent, and national requirements is equipped with protector for this reason.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of insulating protective cover can isolating personnel and earth electrode, high-tension apparatus in live line working.
The technical solution adopted in the present invention is: a kind of high voltage load switch binding post insulating protective cover, comprises, main body and plate; Described main body is Baltimore groove, and in described main body, interval is welded with baffle plate, and the both sides, lower end of described main body are formed with slideway; Described inserting board enters in the slideway of main body, closes the bottom of main body.
Described baffle plate is arch, arch opening and binding post magnetic post fluid-tight engagement; The distance of described adjacent screen is greater than the length of wiring magnetic post.
The making material of described main body and plate is polyethylene insulation material.
The invention has the beneficial effects as follows: owing to employing the insulating protective cover that dielectric strength is the rated voltage of 4.5 times; effectively by the binding post of high voltage load switch insulation isolation; ensure that live line working personnel and the safe distance facing phase terminal and earth electrode; this protective cover reaches the regulatory requirements of preventive trial; meet the requirement of live line working specialty, thus ensure that the life security of operating personnel.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figure 1 to Figure 3, high voltage load switch binding post insulating protective cover of the present invention, comprises, main body 10 and plate 20, and the making material of main body 10 and plate 20 is polyethylene insulation material; Described main body 10 is Baltimore groove, and in described main body 10, interval is welded with baffle plate 11, and the both sides, lower end of described main body 10 are formed with slideway 12; Described plate 20 inserts in the slideway 12 of main body, closes the bottom of main body 10.Described baffle plate 11 is arch, arch opening and binding post magnetic post fluid-tight engagement; The distance of described adjacent screen 11 is greater than the length of wiring magnetic post.
Operation principle of the present invention is: during use, first plate is extracted out in groove, mask main body is directly installed on to be treated on work 10kV high voltage load switch binding post, plug slot, realize isolating the insulation of 10kV high voltage load switch binding post to be changed and surrounding electric equipment, effective restriction instrument of operating personnel and arm scope of activities, when ensureing operation human body with face phase connection terminal and earth electrode has enough safe distances.
Insulating protective cover of the present invention is reasonable in design, simple to operate, low cost of manufacture, security reliability is high, it is a kind of novel 10kV high voltage load switch binding post insulating protective cover being applicable to applying, use high voltage load switch binding post insulating protective cover reliably binding post to be changed can be carried out insulation to cover, ensure that human body and the safe distance facing phase connection terminal in live line working process, in turn ensure that the insulation of human body and switch-mode metal earthing of casing body is isolated, solve in charged for replacement high voltage load switch process because human body is with to face phase connection terminal safe distance not enough and jeopardize the huge hidden danger of operating personnel's life security.
