Oil immersed transformer oil discharge and nitrogen charge fire extinguishing device

The utility model discloses an oil immersed transformer oil discharge and nitrogen charge fire extinguishing device, which is applied to a large oil immersed power transformer and the fire fighting unit similar to the fast response of the oil-charge power equipment, and mainly comprises a fire hydrant cabinet (10), a control cabinet (8), a nitrogen charge pipeline (3) and an oil discharge valve (7) which are arranged in the fire hydrant cabinet (10), and the like. The bottle valve of the power source of the existing oil immersed transformer oil discharge and nitrogen charge fire extinguishing device is always under the open state, and the nitrogen charge pipeline (3) is always under the high-pressure state, which can easily cause that the fire extinguishing device is under maloperation and fails to operate. In the utility model, a starting bottle (1) is arranged to be used as drive source for opening a high-pressure nitrogen cylinder (11), a membrane-type bottle valve (4) is arranged on the high-pressure nitr
