Protective grounding box with stable closing

Abstract

The invention provides a protective grounding box with stable closing. A voltage detection module, an infrared probe and a processor are arranged on the grounding box, a three-phase switch and a closing conductive groove are matched to realize grounding, a baffle is symmetrically arranged in relative to the closing conductive groove, the baffle realizes blocking against grounding of the three-phase switch, safe switching and line maintenance are further realized, mistaken reclosing operation is avoided, and happening of short circuit accidents can be effectively prevented. The closing conductive groove is connected with a ground wire, the closing conductive groove is arranged on a closing seat through a second spring, and when the three-phase switch is contacted with the closing conductivegroove, stable contact between the three-phase switch and the closing conductive groove is realized under effects of the second spring, stable grounding is realized, the stability and the safety of grounding are improved, and the phenomenon that excessive large force for closing causes damages to the closing seat and the service life of the grounding box is shortened can be avoided.

Description

technical field [0001] The invention relates to a grounding box, in particular to a protective grounding box with stable closing. Background technique [0002] With the rapid development of my country's economy and the increasing improvement of people's lives, urban and rural electricity consumption continues to increase, and higher and higher requirements are put forward for the management of low-voltage power distribution. At present, in low-voltage lines, since this part of the power equipment directly provides power to users, the probability of users touching it is relatively high. In order to avoid personal electric shock casualties, almost all lines are erected with insulated wires. Stripping the wires will cause damage to the wires and reduce the health level of the wires. At the same time, there is a possibility of user reverse power transmission, personal electric shock and casualties, and the safety level is low. Therefore, when the line is under power outage main...

AI Technical Summary

Problems solved by technology

It is impossible to judge scientifically and intelligently whether there is residual voltage when the power failure line is running, and it is impossible to guarantee the safety of line equipment and personal safety

Moreover, during the closing process, the closing stability cannot meet the needs of actual use. After closing, it is easy to disconnect or close due to the gravity of the switch blade after opening, which affects the normal operation of power maintenance and even endangers maintenance personnel. personal safety
