On-line monitoring system of high-voltage isolation switch

Abstract

An on-line monitoring system of a high-voltage isolation switch comprises an on-line monitoring terminal, an intelligent control terminal and a display. The on-line monitoring terminal comprises an MCU control unit, an attitude sensor and a wireless transmission module, the three-axis turntable, the attitude sensor and the wireless transmission module are connected with the MCU control unit, and the intelligent control terminal is connected with the display; and the attitude sensor collects disconnecting switch data and transmits the data to the MCU, the MCU processes the data and transmits the data to the wireless transmission module, the wireless transmission module sends the data to the intelligent control terminal, the intelligent control terminal receives the data sent by the wireless transmission module, and the intelligent control terminal transmits the data to the display. Data of the disconnecting switch are collected in real time through the attitude sensor, the rotation angle and the change condition of the disconnecting switch are calculated, so that whether the disconnecting switch is switched on and switched off in place or not is judged, monitoring data are sent in a wireless transmission mode, and state information of the disconnecting switch can be monitored in real time.

Description

technical field [0001] The invention relates to the field of electric power information, in particular to an on-line monitoring system of a high-voltage isolating switch. Background technique [0002] As an important primary electrical equipment of the smart substation, the intelligent high-voltage isolating switch is an important component for isolating voltage and ensuring the safety of other primary equipment during substation maintenance. One of the key technologies for inspection, active early warning, intelligent decision-making and other functions. The traditional operation and maintenance method of operating the isolating switch in manual switching mode is no longer applicable, and there are common problems such as complicated process, heavy repetitive workload, low operation efficiency, and high safety risk. Before the operation, it needs to go through multiple links such as receiving orders, writing tickets, reviewing, and simulating, and the steps are cumbersome....

AI Technical Summary

Problems solved by technology

[0003] At present, some stations use image recognition, pressure sensing and other methods to assist in judging the position status of the isolation switch, but the above-mentioned position monitoring methods still have many problems in terms of stability, accuracy and adaptability. For example, the image recognition algorithm is complex and accurate. The accuracy is not high, the pressure sensing method is difficult to install, and it is impossible to implement uninterrupted deployment and replacement, etc.

The existing monitoring methods for the opening and closing positions of the isolating switch have certain limitations, and new technical methods and technical means need to be found to realize the accurate judgment of the opening and closing positions of the isolating switch
