Foldable low-voltage discharging rod

Abstract

A foldable low-voltage discharging rod comprises an insulation operating rod, wherein the insulation operating rod comprises a grab handle and a foldable handle which are hinged and connected; a discharging conductor is fixedly connected to the free end of the foldable handle, and is electrically connected with a ground wire; the two ends of the ground wire are fixedly connected with retaining clips; one of the retaining clips is connected with the discharging conductor; a groove is formed in the grab handle, and the opening of the groove faces to one side of the grab handle; after the foldable handle is folded, the discharging conductor is positioned in the groove; the grab handle and the foldable handle are hinged and connected through a connecting bolt; the discharging conductor is pressed and limited at the free end of the foldable handle through a positioning bolt. According to the invention, through the reference of the principle of a high-voltage discharging rod, the low-voltage discharging rod with the foldable structure is manufactured, so that an operator can keep a certain safe distance away from the positions likely to be charged; the insulation operating rod comprises the grab handle section and the foldable handle section which are mutually hinged, the discharging conductor is mounted at the front end of the foldable handle positioned at the front end of the insulation operating rod, and the discharging conductor is connected with the ground wire through one of the retaining clips, so that ground discharge is realized, the use is safe, and the operation is convenient.

Description

technical field [0001] The invention relates to a mining device, in particular to a foldable low-voltage discharge rod. Background technique [0002] When performing repair and maintenance work on various electrical equipment, "power failure, power inspection, discharge, installation of grounding wires, and hanging warning signs" have become an essential control process for electrical work. According to the "Coal Mine Safety Regulations" No. Article 45 stipulates that "before maintenance or relocation, the power supply must be cut off and the gas shall be checked. When the gas concentration in the air flow of the roadway is lower than 1.0%, it shall be checked with an electric test pen suitable for the power supply voltage; The conductor can be discharged to the ground." "Electrical Industry Safety Engineering Regulations" also stipulates relevant regulations on the discharge work, "Before and after measuring the insulation, the equipment under test must be discharged to the...

AI Technical Summary

Problems solved by technology

However, when overhauling low-voltage electrical equipment below 1140V, it is inconvenient to discharge because there is no suitable low-voltage discharge rod at present. If a high-voltage discharge rod is used, it is rarely used because it is inconvenient to carry and use.

In actual work, the staff generally use wires or electrical tools to discharge to the ground directly after the electrical inspection, which will inevitably cause a risk factor of personal injury
