Abstract
A low-voltage arc-prevention shield is provided with a shield-shaped cover made of a transparent resin thin plate in the middle of which a round hole is formed, the round hole is connected with a round tube, the external diameter of the round tube is the same as the internal diameter of the round hole, the middle of the outer wall cylindrical surface of the round tube is connected with the opening of the round hole in the middle of the shield-shaped cover, and a handle is arranged at the back of the shield-shaped cover. The round tube is matched with a hand of an operator, wearing an insulating glove, in size. Before the use, the operator wears the insulating gloves, holds the handle at the back of the shield-shaped cover with one hand and stretches the other hand wearing the insulating glove through the round tube to pull for switching on, and when arcs are generated at the instant of manual switching-on, because the operator and a switch are isolated by the shield-shaped cover, the arms, the face and the chest of the operator can be effectively protected against arc burning. As the shield-shaped cover is made of a transparent resin thin plate, observation and operation are not influenced during switching.
Description
Technical field
The present invention relates to a kind of low-voltage power electrician switching on/assisting tool, the low pressure arc protection shield of particularly using during a kind of low-voltage power electrician switching on/operation.
Background technology
The interior lines personnel of low-voltage power power distribution network are carrying out user's low voltage three-phase when sending electricity, owing to the reasons such as excessive or wiring error of loading, can produce electric arc in manual switching on/moment, near the electric arc that the produces operating personnel the electric brake that to burn, although operating personnel's hand shovelling insulating glove, when manual switching on/, the electric arc of generation also can burn operating personnel's arm, face and chest.There is larger potential safety hazard in the electrician when manual switching on/.
In the prior art, not when manual switching on/, can effectively prevent electric arc burn operating personnel's aid.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, propose a kind ofly when manual switching on/, can effectively prevent electric arc burn operating personnel's low pressure arc protection shield.
The present invention is achieved using the following method.
The shield shape cover that low pressure arc protection shield has the transparent resin thin plate to make, there is circular hole at the middle part of shield shape cover, and circular hole is connected with pipe, and the external diameter of pipe is identical with the internal diameter of circular hole, the centre on the circular tube external wall face of cylinder is connected on the circular hole aperture at shield shape cover middle part, and there is handle the back of shield shape cover.
Pipe of the present invention and operating personnel's the size of wearing on hand behind the insulating glove matches.The present invention must use by the coordinated insulation gloves.Before the use; operating personnel's hand is worn insulating glove; the handle of a hand-held shield shape cover back; the hand that another is worn insulating glove passes from pipe of the present invention; during switching on/, with the combined floodgate that pulls that passes pipe of the present invention, when manual switching on/moment generation electric arc; because the isolation of shield shape cover is arranged between operating personnel and the electric brake, can effectively protect operating personnel's arm and face's chest not by electric arc burn.Shield shape cover of the present invention is to make with the transparent resin thin plate, does not affect when the switching on/operation and observes and operation.
Below in conjunction with accompanying drawing, the present invention is further described.
Description of drawings
Fig. 1 is that the master of a kind of low pressure arc protection shield of proposing according to invention scheme of the present invention looks schematic diagram;
Fig. 2 is that schematic diagram cuts open in the office of overlooking of Fig. 1;
Fig. 3 is the A-A generalized section of Fig. 1.
The specific embodiment
Among Fig. 1 ~ Fig. 3, the shield shape cover 1 that low pressure arc protection shield has the transparent resin thin plate to make, shield shape cover is the arc of round rectangle, the length of arc is 500 ~ 700 millimeters, width is 300 ~ 500 millimeters, there is circular hole 2 at the middle part of shield shape cover, circular hole is connected with pipe 3, the external diameter of pipe is identical with the internal diameter of circular hole, the internal diameter of pipe is 100 ~ 200 millimeters, the length of pipe is 150 ~ 300 millimeters, and the centre on the circular tube external wall face of cylinder is connected on the circular hole aperture at shield shape cover middle part, and there is handle 4 back of shield shape cover.
