Abstract
Description
Technical Field
[0001] The invention relates to the field of discharge, in particular to a local discharge positioning device. Background Art
[0002] Discharge is to make a charged object uncharged. Discharge does not eliminate the charge, but causes the transfer of charge. The positive and negative charges cancel each other out, making the object non-electrical.
[0003] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. For cables used for electric energy transmission, it is necessary to improve the safety of power cables. Cables need to be scrapped after long-term operation due to their reduced service life, and they need to be discharged after being scrapped to avoid safety hazards caused by the presence of current inside them.
[0004] When the cable is partially discharged, the discharge end of the cable needs to be connected to the ground rod to transfer the current to the ground for discharge. Due to the lack of a positioning structure, the cable being discharged may be displaced, which may affect the discharge effect at the least, and may cause the discharge end of the cable to come into contact with the worker's body, causing electric shock, posing a safety hazard. In addition, there is a lack of structure to detect the discharged cable after discharge, and it is impossible to accurately know whether there is current in the cable after discharge. If current still exists, it will cause harm to the worker.
