Embodiment Construction

[0016] The present invention is a kind of high-voltage opening and closing safety operating handle, such as Figure 1-Figure 3 shown. In the present invention, a handle 2 is connected to the wide hook 1, and both the wide hook 1 and the handle 2 are integral structures made of insulating materials ， And regular pressure to ensure safe operation. The front part of the wide hook 1 is in the shape of a curved hook, and the rear part of the wide hook 1 is a structure with a recess in the middle, so that the rear part of the wide hook 1 is formed into two protruding tails. A handle 2 is fixedly connected between the two tails.

[0017] When operating to open the high-voltage knife switch, only the electric workers need to hold the handle at 2 places, and directly hook the wide hook 1 at the front of the high-voltage switch safety operating handle to the high-voltage knife switch operating handle. Since the operator does not need to directly touch the high-voltage knife switch ...

Abstract

The invention relates to the technical field of switch tools of high-voltage switches, in particular to a safe operating handle of a high-voltage switch. The safe operating handle can effectively prevent people from being injured by arc light and electric shock accidents from happening. A handle body is connected on a wide hook. The safe operating handle is made of insulating materials, so effective insulation between a hand of a person switching on or off the switch and the switch is guaranteed on the condition that an operator does not need to additionally wear an insulating glove, safety of switching on and switching off can be guaranteed, and the occurrence rate of dangerous electric accidents or arc light discharging accidents caused by electric shock voltage and induction potential is reduced. The safe operating handle has the advantages of being simple in structure and convenient to use, can effectively insulate, is not influenced by external environment, can effectively solve the problem that the insulating glove is prone to being hard during the switching on and the switching off in winter in the north, and enables safety performance during operation of the high-voltage switch to be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of an opening and closing tool for a high-voltage knife switch, in particular to a high-voltage opening and closing safety operating handle, which can effectively prevent arc light from hurting people and electric shock accidents. Background technique [0002] At present, some switches are opened and closed by operators wearing insulating gloves to operate high-voltage switches and knife switches. When encountering high-voltage switches and knife switches with high voltage or line faults, high-voltage knife switches may be charged or arc discharge danger. However, in many cases, in order to prevent the human body from dangerous electric shock voltage, the operator generally wears insulating gloves for operation as required, but in northern my country, due to the low temperature in winter, the insulating gloves often become very hard, which affects the operation The flexibility and convenient performance are p...
