Real-time monitoring system and method for GIS equipment knife switch opening and closing state confirmation

Abstract

The invention discloses a real-time monitoring system and method for GIS equipment knife switch opening and closing state confirmation. The monitoring system comprises a video sensor, a receiving device and a video monitoring background system, wherein the video sensor is installed on a nearby bracket of a knife switch control mechanism and is used for carrying out real-time image acquisition andreal-time result processing on a word turning board on a control mechanism box so as to achieve auxiliary judgment of the on-off state of a knife switch in GIS, the receiving device is connected withthe video sensor and the video monitoring background system, and the receiving device receives an identification result of the video sensor on the word turning plate board and performs further video analysis to obtain the state of the knife switch. According to the invention, auxiliary judgment of the on-off state of the switch contact inside the knife switch can be realized, and double confirmation of the knife switch state in one-key sequential control operation is realized.

Description

Technical field [0001] The invention relates to the field of intelligent monitoring of substations, in particular to a real-time monitoring system and method for confirming the opening and closing states of GIS equipment. Background technique [0002] Knife gates, that is, isolation switches, are one of the core equipment in substations. They are mainly used to reliably isolate the parts that need to be powered off and live parts in the high-voltage power distribution device to ensure the safety of maintenance work. Therefore, the improper opening and closing of the knife and switch will have a very important impact on the normal operation of the line and the life safety of the substation maintenance personnel. [0003] At present, the judgment of the opening and closing state of the knife switch generally adopts the traditional auxiliary switch contact with human observation. This method has big problems in the actual use. One is that the traditional auxiliary switch contacts are ...

AI Technical Summary

Problems solved by technology

[0003] At present, the judgment of the opening and closing state of the knife switch generally adopts the traditional auxiliary switch contact combined with the human eye observation method. This method has relatively large problems in the actual use process. Due to wear, motor aging and other reasons, the information transmission will be wrong; second, it takes a lot of manpower and time to reconfirm through human eye observation, and there is still considerable uncertainty in the judgment of the result; finally, this judgment method does not conform to The current intelligent thought of "one-button sequential control"

For the knife switch in GIS equipment, because it exists in a fully enclosed environment, it is more difficult to directly observe the opening and closing state of the knife switch through human eyes, and its state monitoring is difficult.
