Description

Technical Field

[0001] The utility model relates to the technical field of transformer oil storage cabinets, in particular to a double-airbag oil-immersed transformer oil storage cabinet. Background Art

[0002] Oil-immersed transformers are important equipment in the power distribution system. Maintaining the normal operation of the transformer is an important guarantee for various production activities. The oil conservator, as an important safety component of the transformer, also affects the normal operation of the transformer. The airbag oil conservator uses a rubber capsule to separate the transformer oil from the external atmosphere and provide space for the transformer oil to expand and contract due to heat and cold.

[0003] At present, the dual-airbag oil-immersed transformer oil conservator on the market has the following disadvantages: most oil-immersed transformer oil conservators generally contain only one airbag, so when the airbag is damaged, the transformer has to stop working to replace the airbag, which is inconvenient and affects the daily electricity consumption of surrounding residents;

[0004] For this reason, we designed a double-airbag oil-immersed transformer oil conservator. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a double-airbag oil-immersed transformer oil conservator which is highly practical, can be simply operated and has a relatively simple structure, thereby solving the problem in the above background technology that when the airbag is damaged, the transformer has to stop working to replace the airbag.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a double-airbag oil-immersed transformer oil storage cabinet, comprising a fixing box, a first airbag is fixedly connected to one side of the surface of the fixing box, a second airbag is fixedly connected to the other side of the surface of the fixing box, a circular hole is opened at the center of the bottom of the fixing box, a cylinder is movably connected inside the circular hole, a first limiting plate is fixedly connected to the bottom of the cylinder, a second limiting plate is fixedly connected to the top of the cylinder, an air hole penetrating the cylinder is opened on the surface of the cylinder, an air guide hole is opened on the top of the cylinder, the air guide hole is through-connected with the air hole, a hydraulic rod is fixedly connected to the top of the cylinder, and one end of the hydraulic rod is fixedly connected to the top wall inside the fixing box.

[0007] Optionally, a conduit is fixedly connected to the surface of the air guide hole at the top of the cylinder, and the conduit passes through the fixing box. The conduit extends outside the fixing box to facilitate connection with an external hair dryer to inflate the first airbag and the second airbag.

[0008] Optionally, both sides of the top of the fixing box are fixedly connected to the oil conservator by bolts, and the bolts can conveniently disassemble the fixing box, and the surface of the oil conservator is fixedly connected to legs.

[0009] Optionally, air guide holes are opened on both sides of the fixing box, and the air guide holes are located between the first airbag and the second airbag. The air guide holes can be connected with the air holes on the surface of the cylinder to inflate the second airbag.

[0010] Optionally, the first airbag is located inside the second airbag and can protect the second airbag after the second airbag is damaged. The first airbag and the second airbag are made of rubber.

[0011] Optionally, a slot matching the fixing box is provided on one side of the surface of the fixing box, the slot is convenient for placing the fixing box, and threaded holes matching the bolts are provided on both sides of the slot.

[0012] The utility model provides a double-airbag oil-immersed transformer oil storage cabinet, which has the following beneficial effects:

[0013] The double-airbag oil-immersed transformer oil storage cabinet comprises a fixing box, a first airbag, a second airbag, a cylinder, a first limiting plate, a second limiting plate and a hydraulic rod. The hydraulic rod is opened to drive the cylinder to move upward, so that the air holes on the surface of the cylinder are connected with the air guide holes on both sides of the fixing box, and at the same time, the first limiting plate is pressed against the bottom of the fixing box to prevent it from moving. When the conduit is connected to an external hair dryer, the second airbag is blown up. If the second airbag is damaged, the hydraulic rod is opened to push the cylinder, so that the second limiting plate is pressed against the inner bottom wall of the fixing box, and at the same time, the air holes on the surface of the cylinder leak into the first airbag to inflate the first airbag. When the first airbag is filled with air, the first airbag just fits the second airbag, and the second airbag can protect the first airbag, so that when the second airbag is damaged, the transformer can still work normally, thereby improving the practicality of the device.
