Oil pressure synchronous vacuum device

The utility model provides an oil pressure synchronous vacuum device which is used for detecting an oil leakage point of a transformer and comprises a controller, a vacuum assembly, a vacuum electromagnetic valve, a check valve, a breather pipeline connector and a pressure switch assembly. The breather pipeline connector is communicated with a breather pipeline of the transformer, and the pressureswitch assembly is communicated with an oil filter valve of the transformer. The controller is electrically connected with the vacuum electromagnetic valve and the pressure switch assembly through control cables. The respirator pipeline connector, the check valve, the vacuum electromagnetic valve and the vacuum assembly are sequentially communicated. The vacuum assembly comprises a Roots pump, avacuum pump and a vacuum valve; the roots pump, the vacuum pump and the vacuum valve are sequentially communicated, and the vacuum valve is arranged between the roots pump and the vacuum electromagnetic valve and communicated
