High-voltage electrified automatic alarm

Abstract

The invention relates to the technical field of alarms, in particular to a high-voltage electrified automatic alarm, which comprises a control circuit board and a work circuit board. Specifically, a work circuit support is disposed in a shell of the alarm, and the lower portion of the work circuit support is provided with the control circuit board which is connected with a high-voltage end electrode. The upper portion of the work circuit support is provided with the work circuit board which is connected with the control circuit board. A battery pack and a self-check switch are respectively connected on the work circuit board. The high-voltage electrified automatic alarm is capable of clearly distinguishing whether equipment is electrified or not, has self-check function and checks alarm condition, avoids hidden safety dangers caused by failure of the alarm, ensures safety of operators, is low in cost, small in size and long in service life and stand-by time, does not affect equipment insulation or change equipment structure, is suitable for various electrified places and capable of clearing indicating electrified parts and ensuring human safety of operators and is a safety protection auxiliary device of the human body.

Description

technical field [0001] The invention relates to the technical field of an alarm, in particular to a high-voltage charged automatic alarm. It is suitable for all kinds of places with electricity, and can clearly indicate the live parts to ensure the personal safety of workers. It is an auxiliary device for personal safety protection. Background technique [0002] In places that need to have exposed high-voltage live parts, such as power plants, substations, high-voltage test sites, production workshops, etc., accidents of personnel induction are prone to occur, and there are serious safety hazards. Installing a live alarm device on the live part can effectively prevent people from accidentally touching the live part. [0003] And there is no high-voltage charged automatic alarm device in the market now. The always-on alarm is routinely used in the market, and there are certain defects. The battery life of this alarm is short, it is impossible to distinguish whether there i...
