Description

Visual discharging rod

Technical Field

The utility model relates to a discharging rod technical field especially relates to a visual discharging rod.

Background

When the electric power operation personnel carry out the experimental operation of overhaul of the equipments, need to carry out power failure, test the electricity, discharge operation to field device, the equipment has a power failure after the staff through handheld type discharge rod that colludes, link together with earth connection, ground connection stake, discharge to equipment to ground. Before use, the appearance of the discharge rod, the ground line, the ground chuck and the discharge resistance should be checked. Before discharging, a grounding chuck is connected to a grounding electrode; during discharging, a hand holds a grab handle below the protective ring, slowly approaches the contact hardware to the discharged equipment until the contact hardware is completely contacted, and direct grounding is not allowed until no spark exists after repeated discharging. After a certain time of discharge, the operator can start testing and regular inspection of the equipment. In order to prevent the discharge resistance from being damaged, the operator cannot immediately discharge the discharge after performing the dc withstand voltage test on the large-capacity device (such as a long-distance power cable), and the operator waits for 2 minutes before discharging. When the equipment discharges, operating personnel must dress insulating boot, edge boots gloves and stand on insulating pad, just can ensure personal safety.

The existing discharging rod needs to be repeatedly and directly close to a contacted hardware fitting to the discharged equipment until the discharging rod is completely contacted, the discharging rod can be grounded and discharged after repeated discharging for several times and directly after no spark, after a long discharging process, the large-capacity equipment still has the condition that residual charge is not discharged, the testing personnel still have electric shock risks, the existing discharging rod cannot sense the charged condition of the equipment and cannot prompt the charged state of the equipment, whether the equipment is still charged or not cannot be judged, the residual charge is large or small, and the like, so that the misjudgment of workers and the electric shock risk accidents of the workers are easily caused.
