Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer which is convenient for replacing transformer oil. Background Art

[0002] Transformers are basic equipment for power transmission and distribution, and are widely used in agriculture, industry, transportation, urban communities and other fields. There are about 17 million transformers in operation in my country, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, and have great energy-saving potential. Its specific structure is a transformer that is easy to replace transformer oil, as proposed in patent number CN217562364U, including a transformer, one side of the outer wall of the transformer is fixedly connected to an oil tank, the top of the oil tank is provided with an oil inlet, the bottom of the oil tank is provided with an oil outlet, and the bottom of the oil outlet is provided with an electric valve, the connecting plate is detachably connected to the outer wall of one side of the transformer, the linear motor is fixedly connected to the top of the connecting plate, and the output end of the linear motor is detachably connected to the oil replenishing barrel. By setting the fixed block directly above the control switch, when the oil in the oil tank continuously pours into the collecting bucket from the oil outlet, the gravity of the collecting bucket gradually increases, and the spring is compressed accordingly. When the fixed block on the collecting bucket presses the control switch, the old oil in the oil tank has been drained, and the electric valve is immediately controlled to close and the linear motor is operated.

[0003] With the above arrangement, a transformer in the prior art that is convenient for replacing transformer oil is used by fixing the connecting plate on the transformer, aligning the collecting bucket with the oil outlet, and the oil outlet is to be extended into the collecting bucket, pressing the oil outlet, and opening the electric oil valve. At this time, the oil in the oil tank will continuously flow into the collecting bucket, which will drive the spring to compress and the collecting bucket to descend. When the fixing block on the collecting bucket presses the control switch, the control switch controls the electric oil valve to close the oil outlet and drive the oil replenishing bucket to rise. When the oil replenishing bucket contacts the top plate, the new oil will continuously flow into the oil tank through the oil filling pipe in the oil replenishing bucket, thereby achieving the oil changing effect. However, the prior art solution has the following defects during operation:

[0004] A transformer in the prior art that is easy to replace transformer oil has the following steps: by pressing the oil outlet, the electric oil valve is opened, and the oil in the oil tank flows into the collecting bucket. The collecting bucket descends and drives the spring to compress. When the fixed block on the collecting bucket presses the control switch, the control switch controls the electric oil valve to close the oil outlet and make the oil replenishing bucket rise. When the oil replenishing bucket contacts the top plate, the new oil will flow into the oil tank along the oil filling pipe through the oil replenishing bucket to achieve the oil changing effect. However, after the entire oil changing process is completed, the replaced oil in the collecting bucket needs to be processed, and the connecting plate needs to be removed. By tilting the connecting plate, the spring and the collecting bucket are tilted, and the replaced oil is poured out. When the collecting bucket is tilted, the spring fixed to it will be damaged. Utility Model Content

[0005] The utility model is intended to provide a transformer which is convenient for replacing transformer oil, and is mainly used to solve the technical problem in the prior art that after the entire oil changing process is completed, the replaced oil in the collecting barrel needs to be processed, and the connecting plate needs to be disassembled, and the spring and the collecting barrel are tilted by tilting the connecting plate to pour out the replaced oil, and when the collecting barrel is tilted, the spring fixedly connected thereto will be damaged.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A transformer which is convenient for replacing transformer oil comprises a transformer main body and an oil tank which is fixedly connected to the outer wall of the transformer main body, the upper surface of the oil tank being fixedly connected to an oil inlet, the outer wall of the oil inlet being sleeved with an oil pipe, the lower surface of the oil tank being fixedly connected to an oil outlet, the transformer main body being fixedly connected to a fixed seat on one side close to the oil tank, the outer wall of the fixed seat being slidably connected to a movable seat, the outer wall of the movable seat being rotatably connected to a collecting box, the outer wall of the fixed seat being fixedly connected to a limiting component for limiting the movable seat, the outer wall of the fixed seat being provided with a rectangular groove, the interior of the rectangular groove being slidably connected to a rectangular block, one side of the rectangular block being fixedly connected to an oil change box, the oil change box being fixedly connected to the oil pipe, and the upper surface of the fixed seat being rotatably connected to a driving component for driving the rectangular block.

[0008] The working principle and beneficial effects of the utility model:

[0009] 1. Working principle: When it is necessary to replace the transformer oil of the transformer that is easy to replace the transformer oil, the oil outlet of the oil tank is opened to allow the oil to flow into the collecting box through the oil outlet. When the weight of the oil in the collecting box reaches a certain level, the limit assembly cannot limit the movable seat. At this time, the oil outlet is closed, and the movable seat moves along the outer wall of the fixed seat and drives the collecting box to move together. Under the action of the limit assembly, the collecting box can move more stably. During the movement of the movable seat, the driving assembly will drive the rectangular block to move along the inner wall of the rectangular groove, and the rectangular block will drive the oil change box to move. When the oil change box moves a certain distance, the oil in the oil change box will flow into the oil tank along the oil pipe. After the operation is completed, rotate the collecting box to pour out the old oil in the collecting box.

[0010] 2. Beneficial effects:

[0011] (1) This scheme sets a limit assembly and a drive assembly. When it is necessary to replace the transformer oil of the transformer that is easy to replace the transformer oil, the old oil is discharged from the oil tank into the collection box along the oil outlet. When the weight of the oil in the collection box reaches a certain level, the limit assembly cannot limit the movable seat and the collection box, so that the movable seat drives the collection box to move together. After the movable seat moves a certain distance, the drive assembly drives the rectangular block and the oil change box to move. When the oil change box moves a certain distance, the oil in the oil change box can flow into the oil tank along the oil pipe.

[0012] (2) In this solution, both ends of the fixing rod are slidably connected to the triangular plate through ball bearings. This design allows the fixing rod to move more stably along the outer wall of the triangular plate, so that the fixing rod can prevent the collection box from shaking when it moves.

[0013] Preferably, the limit assembly includes a plurality of spring pieces fixedly connected to the outer wall of the fixed seat, a plurality of arc grooves are provided on the side of the movable seat close to the fixed seat, a fixed rod is fixedly connected to the lower surface of the collection box, a plurality of triangular plates are fixedly connected to the outer wall of the fixed seat, and the fixed rod is slidably connected to the triangular plates. When the driving assembly needs to be driven by the movement of the movable seat and the collection box, the arc groove provided on one side of the fixed seat is supported by the spring piece fixedly connected to the outer wall of the fixed seat to limit the movable seat and the collection box. When the oil in the oil tank needs to be replaced, the oil in the oil tank is allowed to enter the collection box by opening the oil outlet. When the weight of the oil in the collection box reaches a certain level, the spring piece cannot support the arc groove, so that the movable seat moves along the outer wall of the fixed seat and drives the collection box to move together. During the movement of the movable seat and the collection box, the driving assembly will drive the rectangular block and the oil change box to move, and after the oil change box moves a certain distance, the oil can be discharged into the oil tank along the oil pipe.

[0014] Preferably, the number of the spring pieces and the arc-shaped grooves are both two. This design enables the spring pieces fixedly connected to the outer wall of the fixed seat to support the arc-shaped grooves provided on the outer wall of the movable seat more stably.

[0015] Preferably, the length of the arc groove is greater than the length of the spring piece after it is fully extended. This design avoids the situation where the arc groove is not long enough to cause the spring piece to be unable to fully extend when the arc groove contacts and squeezes the spring piece.

[0016] Preferably, there are two triangular plates, and both ends of the fixing rod are slidably connected to the triangular plates. This design enables the triangular plates to effectively limit the fixing rod when the fixing rod moves along the outer wall of the triangular plate.

[0017] Preferably, both ends of the fixing rod are slidably connected to the triangular plate through balls. The balls can make the fixing rod more stable when moving along the outer wall of the triangular plate.

[0018] Preferably, the driving assembly includes a screw rod rotatably connected to the upper surface of the fixed seat, the screw rod passes through the rectangular block and is threadedly connected to the rectangular block, one end of the screw rod is fixedly connected to the first bevel gear, the outer wall of the fixed seat is fixedly connected to the L-shaped seat, the outer wall of the L-shaped seat is rotatably connected to the first winding wheel, the end of the first winding wheel away from the L-shaped seat is fixedly connected to the rotating rod, the end of the rotating rod away from the first winding wheel is fixedly connected to the second bevel gear, and the second bevel gear is meshingly connected to the first bevel gear, the outer wall of the movable seat is fixedly connected to the fixing plate, the outer wall of the fixing plate is rotatably connected to the second winding wheel, and a connecting rope is wound between the second winding wheel and the first winding wheel. When it is necessary to replace the transformer oil of the transformer that is easy to replace the transformer oil, the oil outlet is opened to allow the oil in the oil tank to flow into the collecting box along the oil outlet. When the weight of the oil in the collecting box reaches a certain level, the limiting component cannot limit the movable seat, so that the movable seat moves along the outer wall of the fixed seat and drives the collecting box to move. The movable seat drives the fixed plate fixedly connected to it to move, so that the fixed plate drives the second winding wheel connected to its outer wall to move, and the second winding wheel drives the connecting rope to move, so that the connecting rope drives the first winding wheel to rotate, and the rotation of the first winding wheel drives the rotating The rod rotates, causing the rotating rod to drive the second bevel gear fixedly connected to one end of the rod to rotate. Since the second bevel gear and the first bevel gear are meshingly connected, the second bevel gear will drive the first bevel gear to rotate, thereby causing the first bevel gear to drive the screw fixedly connected to it to rotate, causing the screw to drive the rectangular block threadedly connected to it to move along the inner wall of the rectangular groove, and then the rectangular block drives the oil change tank fixedly connected to it to move along the outer wall of the fixed seat, and contacts the fixed seat after moving a certain distance, ensuring that all the old oil in the oil tank enters the collection box, and then the oil inlet is opened, and the oil in the oil change tank will enter the oil tank along the oil pipe.
