Description

Oil bin, device and system for automatically taking oil from transformer Technical Field The invention relates to the technical field of transformer oil sampling, in particular to an oil bin, and a device and a system for automatically taking oil from a transformer. Background The writer searches for (tacd= (transformer AND oil sample taking AND (bin OR cavity) AND film)), AND the closer prior art solution is obtained as follows. The authorized bulletin number is CN109211309B, and is named as an oil pressure comprehensive on-line monitoring device for dissolved hydrogen and micro water in oil of oil filling equipment. The device comprises a hydrogen-micro water integrated sensor, a pressure sensor, a base, an adapter, a signal conditioning unit and a main control unit, wherein the hydrogen-micro water integrated sensor is arranged at the bottom of the adapter and is in sealing connection with an oil taking hole of oil filling equipment, the adapter is provided with an oil outlet, the oil outlet is communicated with the oil taking hole, the top of the adapter is in sealing connection with the base, an oil storage cavity is arranged in the base, a pressure oil guiding hole is arranged at the bottom of the base, one end of the pressure oil guiding hole is communicated with the oil outlet, the other end of the pressure oil guiding hole is communicated with the oil storage cavity, the base is provided with the pressure sensor, and the sensors are sequentially connected with the signal conditioning unit and the main control unit.
