[0002] The gas relay is one of the most important components of the non-electricity protection of the transformer, and is installed on the pipeline between the transformer and the oil pillow. When a fault occurs in the transformer, the gas relay inside generates corresponding action and sends out an alarm signal or trips. Whether the traditional gas relay is domestic or imported, it can only send out a signal after the fault occurs, and does not have the functions of online monitoring, data analysis and fault early warning for the running data of the heavy gas oil flow rate change. The operation and maintenance personnel of the substation can only rely on the on-site manual observation and inspection mode to manually evaluate the running state of the transformer, and the operation and maintenance personnel and time cost are high, the efficiency is low, potential faults cannot be found in time, and the running state of the transformer of each substation cannot be remotely controlled. The intelligent gas relay has been researched at home and abroad, and the intelligent gas relay with the function of online monitoring of the light gas level has been gradually recognized by market demand, but since it has only one sensor, it cannot meet the monitoring and analysis of the oil flow rate fluctuation data between the transformer and the oil pillow.
