Transformer substation wireless temperature measurement and early warning system based on CT power taking

Abstract

The invention discloses a transformer substation wireless temperature measurement and early warning system based on CT power taking. The system comprises a wireless power taking module, an informationacquisition module, a control module and a client module. The wireless power taking module comprises a CT ring, and the CT ring sleeves a transformer high-voltage cable and is electrically connectedwith the information acquisition module; the information acquisition module comprises connected temperature sensors; the information acquisition module transmits temperature information acquired by the temperature sensor to the control module; and the control module is in wireless communication with the client module. According to the invention, the disorder of wiring and power taking is avoided through the wireless power taking module, the danger of manually replacing a battery and detecting a power supply in a strong electromagnetic environment is eliminated, and meanwhile, continuous and stable electric energy is provided for a monitoring system; temperature information of transformer equipment can be accurately mastered through the temperature sensors arranged at fixed points, abnormaltemperature positioning is achieved, faults are monitored in real time, and the reliability and safety of temperature monitoring in the transformer substation are greatly improved.

Description

technical field [0001] The invention relates to the technical field of substation monitoring, in particular to a wireless temperature measurement and early warning system for substations based on CT power acquisition. Background technique [0002] At present, with the rapid development of my country's national economy, the demand for energy is increasing day by day. As a representative of clean energy, the proportion of electricity in my country's primary energy has increased significantly. In order to cope with the rapidly rising power load and the needs of ultra-long-distance power transmission, the construction of the power grid must develop in the direction of UHV, automation and intelligence. But at present, the average failure rate of my country's power grid is high. One of the important reasons is that we lack effective monitoring of the operating status of power equipment. One of the important aspects is the online temperature monitoring of power equipment. For a lo...

AI Technical Summary

Problems solved by technology

The former makes it dangerous and inconvenient to replace the battery in a high-voltage environment; while the latter has high costs for long-distance wiring, and the high-temperature and high-pressure environment leads to a decrease in transmission quality and even damages its own structure;

[0005] (3) Traditional temperature measurement mainly measures the ambient temperature of a certain space in the substation, and cannot accurately measure the temperature of some nodes that are prone to heat

Cannot measure other environmental factors of the substation, etc.
