Problems solved by technology

Especially for the electrical equipment used at the substation site of the power supply bureau, due to the complex test environment on site, large interference, and strong induction current, if the electrical equipment has poor grounding wire contact, broken wire or unconnected wire during use In the case of protective grounding, it loses its protective effect on personal safety.
[0003] At present, the state of the protective grounding wire of electrical equipment still lacks continuous and effective monitoring means

Abstract

The invention discloses a continuous monitoring method of protection grounding states of an electrical device and relates to the technical field of safety protection of electrical devices in electricpower systems. In the method, a PED grounding protection monitoring output end is connected with the grounding end of the electrical device; states of the PED grounding protection monitoring output end are monitored through a single chip microcomputer monitoring unit; and when poor contact, disconnection or failure of wire connection occurs between the PED grounding protection monitoring output end and the ground line, the high level of the PED grounding protection monitoring output end is monitored by the single chip microcomputer monitoring unit, and an alarm unit is controlled to give out sound-light alarms, thereby achieving real-time and continuous monitoring of grounding states of the electrical device and protecting safety of onsite testers. A monitoring device provided by the invention is advantaged by simple structure, reliability, safe use and convenient monitoring.

Description

technical field [0001] The invention belongs to the safety protection technology of electrical equipment in a power system, and in particular relates to a method for continuously monitoring the protective grounding state of electrical equipment. Background technique [0002] During the use of electrical equipment, the metal casing of the equipment needs to be provided with a dedicated protective grounding wire. Especially for the electrical equipment used at the substation site of the power supply bureau, due to the complex test environment on site, large interference, and strong induction current, if the electrical equipment has poor grounding wire contact, broken wire or unconnected wire during use If the situation, the protective grounding loses its proper protective effect on personal safety. [0003] At present, there is still a lack of continuous and effective monitoring means for the status of the protective grounding wire of electrical equipment. Without changing t...
