The invention relates to the technical field of busbars, in particular to a
busbar with an electronic and mechanical double-switching mechanism for electronic special gas and a control method. An electronic switching valve group and a mechanical switching valve group are arranged and are arranged in parallel; the
gas supply unit is communicated with the output main
pipe through the electronic switching valve set and the mechanical switching valve set, automatic switching can be achieved through the electronic switching valve set under the normal working condition, and switching of the
gas supply unit can still be completed through the mechanical switching valve set under the abnormal condition. The dual-redundancy switching mechanism is favorable for avoiding
gas supply interruption caused by failure of a single electronic
system, and effectively solves the problem that the existing electronic special gas supply
system usually conveys gas to a gas using terminal through a
busbar, but the
busbar is usually only provided with an
electronic switching system, so that the gas supply efficiency is greatly improved. And when abnormal working conditions such as power failure, sensor failure or
control circuit failure occur, the standby gas source cannot be switched in time, and gas supply is interrupted.
