System and method for monitoring oil level and oil temperature of transformer

Abstract

The invention discloses a system and a method for monitoring oil level and oil temperature of a transformer. The system comprises the components of an oil level photographing instruction generating module which timely generates an oil level photographing instruction; oil level monitoring equipment which photographs an oil level monitoring image of the transformer according to the oil level photographing instruction and furthermore transmits the oil level monitoring image to a server; an oil temperature acquisition instruction generating module which timely generates an oil temperature acquisition instruction; oil temperature monitoring equipment which acquires the oil temperature of the transformer according to the oil temperature acquisition instruction and transmits the oil temperature to a server; and the server which determines the oil level of the transformer according to the oil level monitoring image, transmits first alarming information when a fact that the oil level of the transformer is higher than a preset oil level upper limit or lower than a preset oil level lower limit is determined, and transmits second alarming information when a fact that the oil temperature is higher than a preset oil temperature threshold. The system and the method have advantages of realizing no requirement for field data acquisition by electric power personnel, ensuring body safety of the electric power personnel, saving time and labor, obtaining high detecting result accuracy, performing overlimit alarming, and satisfying an application requirement.

Description

technical field [0001] The invention relates to the technical field of transformer protection, in particular to a transformer oil level and temperature monitoring system and method. Background technique [0002] In order to ensure the safe and reliable operation of the transformer in the power system, avoid the lack of oil, oil spill and high oil temperature of the transformer caused by overload and internal faults during the operation of the transformer in the power system, which will cause the transformer to catch fire and endanger the line power supply or personal safety. accident, in order to ensure the safe and reliable operation of the transformer, the traditional monitoring of the oil level and oil temperature of the transformer requires the power personnel to use a flashlight to judge the oil level with the naked eye, use a temperature measuring gun to measure the temperature, and then record it through a notebook. This method is time-consuming There may be certain e...
