A low-voltage switch operating device

Abstract

The invention belongs to the field of mechanical structures, and more specifically relates to a low-voltage switch operating device which includes a first joint, a pin, a second joint, a positioning bolt, a rotating rod and an operating rod. The first join and the second joint are rotatably connected by the pin; the second joint is screwed with the operating rod; the rotating rod goes through theoperating rod to be connected to the positioning bolt; the positioning bolt goes through the second joint to make contact with and abut closely against the first joint; and the rotating rod is a rotating rod member. According to the invention, through connecting the low-voltage switch operating device to an operating handle of the switch, pulling the low-voltage switch operating lever is equivalent to adding an extended manipulator to overcome the problems of the original operating handle being short, the operating distance being close and the operating requirements being great, thereby keeping a certain safety distance between operation and maintenance staff and the low-voltage switch, avoiding the accident of people being injured by the electric arc during arc burning, improving the reliability and safety of the operation of the low-voltage switch and effectively preventing the occurrence of electric arc injury accident.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and more specifically relates to a low-voltage switch operating device. Background technique [0002] Distribution network low-voltage switches are widely used in low-voltage power distribution cabinets, multi-position meter boxes, three-phase and single-phase meter boxes. The commonly used low-voltage switch operating handles are relatively short and the operating distance is relatively short. Most low-voltage switches require manual operation and wear insulation. Gloves directly open and close the low-voltage switch, and there are potential safety hazards that the human body will be relatively close to the live equipment, and equipment failure will cause explosion or arc discharge to cause personal injury. [0003] The operating handle of the low-voltage switch is short and the operating distance is short. When the switch is placed in a relatively high workplace, it is necessary to use auxi...

Problems solved by technology

[0004] The present invention aims to overcome the disadvantages of the potentiometric titration system, and provides a low-voltage switch operating device. After connecting the low-voltage switch operating device to the operating handle of the switch, the low-voltage switch is pulled to move the operating lever, which is equivalent to adding an extended manipulator. It overcomes the original problems of short operating handle, short operating distance, and high operating force, and keeps a certain safe distance between the operation and maintenance personnel and the low-voltage switch, avoiding arc injury accidents caused by arcing, and improving the reliability of low-voltage switch operation and safety, effectively preventing the occurrence of electric arc injury accidents
