Problems solved by technology

At present, most power plants use light gas alarm instead of tripping. When a light gas alarm occurs, it is often necessary to verify the authenticity of the alarm. At this time, the transformer area is very dangerous, and the verification of the alarm will involve a very large number of personnel. risk of injury

Abstract

The invention discloses a gas volume monitoring system and method for a gas relay of an oil-immersed transformer, and a storage medium. The gas volume monitoring system comprises: an image collection device which is arranged on a monitoring pane of the gas relay and is used for collecting a picture containing the whole monitoring pane in real time; and a processing device whichis used for processing and analyzing the pictures collected in real time to obtain real-time liquid level information in the gas relay and calculating the gas volume in the gas relay in real time according to the liquid level information. The gas volume of the gas relay of the transformer can be monitored in real time, an alarm can be given immediately when abnormal changes are found, and faults are predicted in advance before light gas alarm; and an action mechanism of light gas alarm is that the liquid level in the gas relay is reduced, so that when the light gas alarm occurs, whether the liquid level of the gas relay is reduced or not can be judged through video monitoring so as to confirm the authenticity of the light gas alarm.

Description

technical field [0001] The invention relates to the field of safety protection of an oil-immersed transformer gas relay, in particular to a gas volume monitoring system, method and storage medium of an oil-immersed transformer gas relay. Background technique [0002] In large-scale power plants, large-scale chemical plants, oil refineries and other factories, oil-immersed transformers are indispensable. They have the functions of raising and lowering voltage and transmitting power, and are an important hub for power transmission. [0003] In recent years, there have been many incidents of fires caused by large oil-immersed transformers due to failures. For example, in June 2016, the main transformers No. 3 and No. 4 of the 330kV substation in the southern suburbs of Xi'an exploded after fire; A transformer deflagrated at Quancheng Station, causing a fire and causing one death and two injuries. Therefore, transformer failure poses a great threat to personal safety and asset ...
