Device for wirelessly monitoring contact temperature of high-voltage switch cabinet

Abstract

The invention provides a device for wirelessly monitoring contact temperature of a high-voltage switch cabinet, which comprises a temperature collecting mechanism, a temperature processing mechanism and a PC (Personal Computer) display terminal; the temperature collecting mechanism has multiple paths which are respectively installed in a contact area of the high-voltage switch cabinet to be monitored; a signal output end of the temperature collecting mechanism is in wireless connection with a signal input end of the temperature processing mechanism; and the signal input end of the temperature processing mechanism is in wired connection with the PC terminal. The device for wirelessly monitoring the contact temperature of the high-voltage switch cabinet provided by the invention is capable of satisfying wireless real-time monitoring on the contact temperature of a high-voltage switch by users, and alarming and prompting under a fault state; furthermore, the device is simple in design, easy for implementation, short in development cycle and low cost; services for medium and small enterprises can be well increased; and the device is more beneficial to being popularized.

Description

technical field [0001] The invention relates to the field of high-voltage switch cabinets for power distribution and transformation, in particular to a wireless detection system for contact temperature of high-voltage switch cabinets. Background technique [0002] In recent years, with the acceleration of power plant automation and information construction, high-voltage switchgear is a very important link in the entire power system. After the long-term operation of the high-voltage switchgear, the contact springs tend to be loose and the contacts are not in good contact, or some parts are aging. If no measures are taken in time, the temperature of the contacts will increase sharply, which will easily cause equipment damage. lead to major electrical accidents. Due to a series of factors such as the closed structure of the high-voltage switchgear, the complex electromagnetic environment, and the isolation of high-voltage and low-voltage equipment, the monitoring device is req...

AI Technical Summary

Problems solved by technology

At present, companies engaged in the development of power monitoring technology in the market, the non-contact monitoring devices they research have relatively complete functions, the system is too complicated, which is not conducive to product installation and maintenance, and the price is high, which is difficult for small and medium-sized enterprise users to accept. When the company considers the market, it pays attention to the versatility of software products, which is relatively lack of pertinence and practicality, and the development cycle is long, the investment is large, and it is not easy to promote
