Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer with an early warning function. Background Art

[0002] A transformer is a device that uses the principle of electronic induction to change AC voltage. Its main functions include voltage conversion, current conversion, impedance conversion, etc. However, for current transformers, when the operating temperature of the transformer is high, a cooling fan is required to dissipate the heat of the transformer.

[0003] The patent announcement number is CN216388960U. The patent provides a transformer with an early warning function. If the operating temperature of the transformer is normal, the cooling fan will keep working, which will waste electricity. Even if the cooling fan can be turned on and off by a temperature control switch, when the cooling fan is turned off and not in use, the heat dissipation net is in a ventilated state for a long time. Dust can easily enter the transformer through the heat dissipation net, which will cause more dust to adhere to the inside of the transformer, affecting the working performance of the transformer. In addition, in heavy snow weather, if the snow is too heavy, it is easy to collapse the transformer. When heavy objects are pressed on the transformer, it is difficult to alarm in time and remind the staff to clean and maintain it, which will shorten the service life of the transformer. In order to solve the problems of the prior art, the patent discloses a transformer with an early warning function, including a body, a heat dissipation protective cover and a heat conductive shield. The heat dissipation protective cover is wrapped around the periphery of the body, and the heat conductive shield is arranged above the protective cover. The above patent solves the problem that the heat dissipation net is in a ventilated state for a long time, and dust can easily enter the transformer through the heat dissipation net, which will cause a lot of dust to adhere to the inside of the transformer and affect the working performance of the transformer. However, some impurities may be generated inside the transformer during heat dissipation. The increase in impurities may increase the temperature inside the transformer and affect the normal use of the transformer. Summary of the invention

The two convex plates are provided to better seal the sewage inlet hole. A torsion spring is provided between the scraper and the round rod. The torsion spring is provided to better allow the scraper to clean the impurities on the filter screen.

[0011] According to the above technical scheme, the oil filling device includes an oil tank, an L-shaped rotating rod, a buoyancy ball, an extrusion rod, a push button, a blocking plate, an elastic gasket, a conical pipe head, a sphere, a gasket, a refueling pipe and a hose.

The push button slides through the baffle plate to push the elastic gasket to seal the conical pipe head. The L-shaped rotating rod rotates to penetrate the refueling pipe. The present invention provides a transformer with an early warning function, which has the following beneficial effects: (1) The invention uses an oil pump to draw oil into the filter, and then draws the oil into the oil pump through the filter. The oil pump then pushes the oil into the oil pillow, and the oil pillow injects excess oil into the main body. After the oil flows through the No. 2 connecting pipe, it will drive the hydraulic fan to rotate and continuously hit the impact rod to drive the filter to vibrate, knocking impurities on the filter and cleaning the filter to a certain extent. By pushing the connecting rod, the movement of the connecting rod will drive the movement of the connecting rod, and the movement of the connecting rod will drive the movement of the rotating rod. The movement of the rotating rod will drive the double-headed rotating plate to rotate. The rotation of the double-headed rotating plate will block the liquid from flowing through the No. 1 connecting pipe into the filter and block the liquid from entering the oil outlet pipe through the No. 2 connecting pipe. At this time, the double-headed rotating plate in the other filtering device will release the obstruction to the oil and allow the oil to flow in. By switching the filtering device, the filter can be replaced more conveniently and quickly without hindering the normal use of the filtering device, which can reduce the time wasted in disassembling and assembling the filter.

[0013] (2) The invention drives the U-shaped rod to move by pushing the connecting rod back and forth. The movement of the U-shaped plate drives the rotating plate to rotate and then drives the round rod to move. The back and forth movement of the round rod drives the scraper to scrape impurities on the surface of the filter screen and slide the impurities into the collection tank through the collection slide. The movement of the round rod drives the arc slot plate to rotate. The rotation of the arc slot plate seals the sewage inlet hole so that excess oil does not enter the collection tank. The rotation of the arc slot plate opens the sewage outlet to discharge the oil and impurities in the collection tank. By collecting and discharging impurities on the filter screen, the use of the transformer will not be affected by excessive impurities inside the main body, and the service life of the oil can be extended.

[0014] (3) In this invention, when the oil in the oil pillow is insufficient, the buoyancy ball will drive the squeezing rod to descend. The descending squeezing rod will release the squeezing on the push button and cause the elastic gasket to pop up. The popping up of the elastic gasket will release the seal on the tapered pipe head, allowing the oil to enter the oil pillow through the oil outlet hole to replenish the oil in the oil pillow. When the oil leaks, the L-shaped rotating rod is rotated. When the L-shaped rotating rod rotates, it will drive the ball to rotate to seal the refueling pipe to block the inflow of liquid and prevent the oil in the tank from flowing out and causing waste.
