The invention relates to a transformer gas relay with a wireless remote deflation device. The transformer gas relay with the wireless remote deflation device is characterized by comprising a gas relay, the gas relay is connected with a deflation solenoid valve, the deflation solenoid valve is connected with a wireless reception module, the gas relay is connected with a conservator through a butterfly valve, and the gas relay is connected with a main transformer body through a connecting pipe. The transformer gas relay with the wireless remote deflation device also comprises a remote controller arranged in a master control room or another control room of a transformer station, and the remote controller comprises a processor and a wireless transmitting module which are used for communicating with the wireless reception module. According to the invention, the main transformer gas relay can be deflated remotely, and working personnel do not need to deflate the gas relay in a transformer station main transformer site, and do not need to climb on the main transformer which is in live line to carry out deflation.
Description
technical field [0001] The invention relates to the field of transformer gas relay control, in particular to a transformer gas relay with a wireless remote gas release device. Background technique [0002] During the operation of the main transformer, due to poor sealing or incomplete degassing of the oil, gas will be generated, especially when a fault occurs, the oil in the main transformer may undergo thermal cracking and generate a large amount of gas. The above gases will accumulate on the gas relay. If the gas is not discharged in time, the gas will discharge under the action of the high-voltage electric field, which will seriously endanger the safe operation of the main transformer. After the maintenance of the main transformer, the replacement of the silicone respirator, oil replenishment, oil filtering, hot oil circulation, and other work that may generate free gas are completed and the power is supplied for 4 hours, the gas must be released on the gas relay to ensur...
