Beschreibung
Zusammenfassung:	The invention relates to an online gas relay calibration system, which comprises a working oil circuit and a first detecting oil circuit used for detecting the flow velocity value of heavy gas. One end of a first working oil pipe is connected with a transformer, and the other end is connected with a gas relay. The first working oil pipe is equipped with a first valve and a second valve. One end ofa second working oil pipe is connected with the gas relay, and the other end is connected with an oil storage tank. The first detecting oil circuit includes a first detecting oil pipe and a second detecting oil pipe. One end of the first detecting oil pipe is connected to the first working oil pipe, and the other end of the first detecting oil pipe is connected with an oil tank. The first detecting oil pipe is equipped with a fifth valve and a flow meter in sequence. One end of the second detecting oil pipe is connected to the second working oil pipe, and the other end of the second detectingoil pipe is connected to
