Abstract

The utility model relates to the technology field of an opening/closing tool of a high voltage knife-switch, in particular to a high voltage opening/closing safe operation handle which can prevent the arc light from hurting people effectively and prevent the electric shock accidents. The high voltage opening/closing safe operation handle of the utility model is characterized that a wide hook is connected with a handle. The high voltage opening/closing safe operation handle of the utility model is made of an insulating material, so that the operation personnel can guarantee the effective insulation between the hands and the switch at the opening and closing operation on the condition of not needing to wear the insulating gloves additionally, and accordingly, the safety of the opening and closing operations is guaranteed, and the incidence rate of the electrified or arc light discharge dangerous accidents, such as electric shock voltage, induced electromotive force, etc., can be reduced. The high voltage opening/closing safe operation handle of the utility model has the characteristics of simple structure and convenient use, can be insulated effectively, is not influenced by the external environment, can effectively solve the problem that the insulating gloves are easy to freeze at the opening and closing operations in the north winter, and enables the safety during the high voltage opening/closing operations to be improved substantially.

Description

High pressure switching safe operation handle

Technical field

The utility model relates to a kind of technical field of switching instrument of high-voltage switch switch, relates in particular to a kind of high pressure switching safe operation handle, and it can effectively prevent that arc light from hurting sb.'s feelings and electric shock accidents.

Background technology

At present, the folding of part switch all adopts operating personnel to wear insulating gloves operate high pressure switch, disconnecting link, and when running into high-voltage switch gear, disconnecting link and have high voltage or during line fault, high-voltage switch has the charged or dangerous generation of arc discharge.But; many times; in order to prevent the adventurous electric shock voltage of human body; operating personnel generally can wear as requested insulating gloves and be operated, but in northern China, because winter temperature is lower; therefore insulating gloves usually can become very hard; thereby flexibility ratio and the convenient performance of impact operation, the phenomenon of misoperation easily occurs, thereby make operating personnel's the personal safety danger of can't being protected.

Summary of the invention

Can not effectively avoid dangerous electric shock voltage and the deficiency of non-hazardous induced potential in order to overcome the switching mode existed in prior art, and the hardening in winter of existing rubber-insulation gloves, unhandy technical problem, the utility model provides a kind of high pressure switching safe operation handle.Its objective is and provide a kind of can not only effectively the insulation to prevent that the accident of human electric shock from occurring, and can be easily at north of china in winter temperature lower place use, not there will be the phenomenon of hardening simultaneously, and a kind of safe operation handle easy to use.

The utility model solves the technical scheme that its technical problem adopts:

High pressure switching safe operation handle is to be connected with handle on wide hook.

The front portion of described wide hook is the hook shape, and the rear portion of wide hook is divided into Intermediate Gray recessed structure, makes the rear portion of wide hook form the afterbody of two protrusions, between these two afterbodys, is connected with handle.

Described wide hook and handle are overall structures.

Described wide hook and handle are all to be made by insulating material.

Advantage of the present utility model and beneficial effect are:

Because adopting insulating material, the present invention makes, therefore operating personnel can be in the situation that need not additionally wear insulating gloves, guarantee effective insulation of switching staff and switch room, guarantee the fail safe of switching operation, reduced the incidence of the charged or arc discharge peril such as electric shock voltage and induced potential.The utility model also has characteristics simple in structure, easy to use.Both can effectively insulate, and not be affected by the external environment again, while effectively solving the north of china in winter switching, the easy stiff problem of insulating gloves, be significantly improved the security performance in the operation of high pressure switching.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the end view of Fig. 1.

In figure: wide hook 1, handle 2.

Embodiment

The utility model is a kind of high pressure switching safe operation handle, as shown in Figure 1-Figure 3.The utility model is to be connected with handle 2 on wide hook 1, and wide hook 1 and handle 2 are all overall structures of being made by insulating material ,and regularly suppress, guarantee job safety.The front portion of wherein said wide hook 1 is the hook shape, and the rear portion of wide hook 1 is divided into Intermediate Gray recessed structure, makes the rear portion of wide hook 1 form the afterbody of two protrusions.Be fixedly connected with handle 2 between these two afterbodys.

When high-voltage switch is opened in operation, only need the electric operating personnel to hold handle 2 places, the wide hook 1 of this high pressure switching safe operation handle front portion directly is articulated on the high-voltage switch operating handle and gets final product.The operating personnel, owing to not needing directly to contact high-voltage switch with hand, therefore is significantly improved the security performance of hot line job.

Claims

1. high pressure switching safe operation handle, is characterized in that: be connected with handle (2) on wide hook (1); The front portion of described wide hook (1) is the hook shape, and the rear portion of wide hook (1) is divided into Intermediate Gray recessed structure, makes the rear portion of wide hook (1) form the afterbody of two protrusions, between these two afterbodys, is connected with handle (2); Described wide hook (1) and handle (2) are overall structures; Described wide hook (1) and handle (2) are all to be made by insulating material.
