Intelligent reminding high voltage presence display device

Abstract

The invention discloses an intelligent reminder high-voltage electrified display device, which comprises a high-voltage electrified sensor installed at a high-voltage pile head and collecting three-phase voltage, and a compensation circuit, an input protection circuit, a current / voltage conversion circuit, and a signal The processing circuit, the signal processing circuit is connected with the programmable control circuit through the wave detection circuit; the infrared sensor for sensing personnel activities is connected with the programmable control circuit; the programmable control circuit is connected with the alarm circuit, and the programmable control circuit is connected with the three-phase charging circuit LED display device connection. The invention collects the three-phase voltage through the high-voltage charging sensor installed at the high-voltage pile head, displays the three-phase charging situation through the LED, and automatically senses whether someone is moving in front of the high-voltage charging display device through the infrared sensor. Voice reminder "high voltage live, please do not approach".

Description

technical field [0001] The invention relates to an intelligent reminder high-voltage charged display device. Background technique [0002] With the development of social economy, high-voltage power distribution equipment spreads all over urban and rural areas, and penetrates into residential areas. On-site electricians usually do not have skilled skills, and these misoperations are likely to cause serious accidents and affect the normal operation of the power system. How to more effectively prompt personnel to prevent strays into live compartments is a realistic demand. [0003] The high-voltage charged display device with static indication is widely used in the production site. The device usually uses a diode to indicate the live state of the line, and transmits the signal of whether the high-voltage charged body is charged or not to the light-emitting element, and displays or locks the high-voltage switch at the same time. The device consists of two parts, the sensor and...

However, in the face of a large number of people, electrical workers with insufficient professional skills, and people who are out of control and sloppy, the on-site warning of this sign is obviously insufficient, and a more active warning method is needed, such as timely and effective sound and light reminders. Wake up on dangerous edges to avoid safety accidents
