Alarm device for loose pile head of substation grounding wire

Abstract

The invention discloses a transformer substation ground lead pile head loosening alarming device which comprises a mechanical device, a power supply device, a signal sending circuit, a signal receiving circuit and an alarming circuit. The mechanical device comprises an outer shell, a plunger, a lifting pin, an electrode, a spring and an adjusting screw. The outer shell is a barrel with the two ends opened, the lifting pin and the adjusting screw are located at the two ends of the barrel and seal the two openings of the barrel respectively, and the inner wall of one end, with the adjusting screw located, of the barrel is arranged as a threaded section to enable the adjusting screw to be capable of being screwed in the opening of the barrel. The transformer substation ground lead pile head loosening alarming device has the advantages of being capable of giving out necessary alarming to remind overhauling, operation and petrol personnel to carry out inspection when wire clamp screws loose and the grounding device does not make perfect contact due to human factors, and so that the accidents that people are hurt by induced electricity people due to poor contact of grounding wires are completely eradcated.

Description

technical field [0001] The invention relates to an alarm device for a loose pile head of a substation grounding wire. Background technique [0002] The purpose of setting a loose alarm circuit at the pile head of the ground wire of the substation is to better implement the application of the ground wire in the "Safety Work Regulations", so as to remind and warn the on-site maintenance personnel and operators to always pay attention to the ground wire (or ground switch) In order to prevent the grounding pile head screw from loosening and the grounding wire from being in poor contact, the maintenance personnel did not find out in time when they were working, causing induction electricity or external electricity to injure the maintenance personnel. Eliminate the occurrence of production safety accidents and make the equipment run safely for a long time. [0003] At present, among the widely existing on-site ground wires, only the ground wire is connected to the ground pile thr...

AI Technical Summary

Problems solved by technology

In the actual maintenance work, due to the poor contact of the ground wire, there is a partition between the ground wire and the maintenance site, falling off and poor contact, often causing induction electricity or external electricity to injure the maintenance personnel

In the process of electric power construction, there are many cases of electric injuries to maintenance personnel due to poor contact of grounding wires or falling off of grounding wires in the power system

From the case, it can be seen that an accident has left a bloody lesson for people, brought huge damage to equipment, brought great fluctuations to the system, and brought huge losses to the country and the people.

[0004] In the prior art, the original grounding fixing device is fixed by the rotation of the conventional wire clip, which causes loosening of the wire clip thread or artificial failure to fix the grounding wire clip during the application, causing electric maintenance personnel to be injured by electric shock or external electric shock during construction. personnel
