A grounding device that can automatically detect continuity

Abstract

The invention discloses a grounding device capable of automatically detecting conductivity. The grounding device comprises a detection module and a ground wire pile connected with a grounding bar of atransformer substation. A ground wire head is arranged on the ground wire pile, wherein one end of the ground wire head is fixedly connected with a ground wire, and the other end of the ground wire head is fixedly connected with the ground wire pile through a locking mechanism. A pressure sensor is arranged between the ground wire pile and the ground wire head. The detection module comprises a differential amplification module, a threshold judgment module, an LED indication module, a microprocessor module, a wireless communication module and a power module. The pressure sensor is connected with the input end of the differential amplification module, and the output end of the differential amplification module is connected with the threshold judgment module and the microprocessor module. The output end of the threshold judgment module is connected to the LED indication module, and the microprocessor module uploads a conductivity result to a monitoring system through the wireless communication module. The device can detect whether the conductivity between the grounding end of the grounding wire and the grounding device is good or not in real time, thereby improving the safety.

Description

technical field [0001] The invention relates to a grounding device, in particular to a grounding device capable of automatically detecting continuity, and belongs to the technical field of power system safety. Background technique [0002] The grounding device is an important line of defense to ensure the safety of electric power maintenance work. Whether the conduction between the grounding wire and the grounding device is good directly determines the work safety of electric personnel. "Q / GDW 1799.1-2013 State Grid Corporation Electricity Safety Work Regulations" stipulates that the grounding end of the grounding wire and the grounding device should be in good contact and the connection should be reliable. However, the traditional grounding device does not have the function of automatic continuity detection. In the actual operation process, electric power personnel judge the degree of compression of the ground terminal completely based on experience, and there is no clear ...

Problems solved by technology

In the actual operation process, electric power personnel judge the degree of compression of the ground terminal completely based on experience, and there is no clear indication of continuity, so it is impossible to accurately judge whether the contact is good, and there is a great potential safety hazard
