Hot fault warning system device

Abstract

The invention relates to an early warning system device for thermal fault, which is characterized in that a system digital temperature collector and a system data receptor are arranged in the early warning system device for thermal fault, a 2.4 GHz data transmission module is employed to conduct wireless data communication, an one-chip microcomputer ICI employs the arrangements of an inner crystal, a timer, inner address and frequency, the one-chip microcomputer ICI is utillized as core, temperature information collecting and wireless emission are realized and concurrently recessed in an armored cassette which is high temperature-resistant and flame-proof. The system data receptor is equipped with an early warning circuit and an auto-reset circuit, and is finished by the one-chip microcomputer ICI controlling the restorer IC3 of the CPU. The invention real-timely monitors the temperature of each monitored point, when reaching a certain temperature, audible and visible alarm reminds the operator on duty of avoiding accident. The invention is a digital and intelligent device which can realize real-time temperature monitoring online, early warning of heating-up and network with computer under the condition of high-pressure apparatus with power.

Problems solved by technology

[0002] With the rapid development of today's science and technology, the equipment in the high-voltage transmission and distribution industry is also updated day by day. Various types of switch cabinets have replaced the older generation of equipment because of their large capacity, small size, tight sealing, and sensitive action. The ensuing problem of hot and red contacts is difficult to detect and measure, resulting in many major accidents in the power transmission and distribution industry

At present, ordinary optical fiber on-line measurement, far-infrared on-line temperature measurement, far-infrared imaging tester and other test methods are in the category of non-monitoring for the contacts, joints and cable heads of the middle-mounted high-voltage switchgear produced at home and abroad in recent years. High-voltage switchgear has safety hazards to varying degrees
