Description

Technical Field

[0001] The utility model relates to the technical field of submersible transformers, and particularly relates to a new type of high-efficiency and energy-saving submersible transformer. Background Art

[0002] Submersible pumps can be roughly divided into four types according to their main uses: submersible pumps for gas stations; large-flow and high-lift submersible pumps for oil depots (fueling ships); submersible pumps for railway tank cars (loading arms); and chemical explosion-proof submersible pumps for flammable and explosive media.

[0003] During the use of extra-high voltage AC transformer equipment, in the past, such large-capacity rectifier transformers generally used forced oil circulation air coolers (referred to as oil-air coolers) for cooling. This is because the overall loss of the rectifier transformer is relatively large, and the oil-air cooler can well take away the heat of the regulating transformer and the main transformer, thereby achieving the effect of high efficiency and energy saving. This oil-air cooler is composed of components such as cooling pipes, fans, and submersible pumps. The insulating oil in the oil tank is transported into the transformer through the submersible pump. Generally, the connection between the submersible pump and the transformer is a horizontal and straight connection. However, the connection between the submersible pump and the transformer is prone to oil leakage after long-term use. Therefore, a new type of high-efficiency and energy-saving submersible transformer is proposed. In order to avoid oil leakage, the connection between the submersible pump and the transformer is improved to avoid such problems. Content of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a new type of high-efficiency and energy-saving submersible transformer. In order to avoid oil leakage, the connection between the submersible pump and the transformer is improved to avoid such problems.

[0005] The technical solution adopted by the utility model to solve its technical problems is a new type of high-efficiency and energy-saving submersible transformer, which includes a transformer and a submersible pump. A first bushing is fixedly connected to the upper part of one side of the transformer. A second chute is opened inside the first bushing for slidingly installing a first liquid inlet pipe. The first liquid inlet pipe is movably inserted into one end of the first bushing away from the transformer. A second slot is provided inside the first liquid inlet pipe. A first liquid outlet pipe is fixedly connected to one side of the submersible pump. A first oil outlet nozzle is provided at one end of the first liquid outlet pipe away from the submersible pump. The first oil outlet nozzle is inserted into the second slot.

[0006] By adopting the above technical solution, the insulating oil pumped out of the oil tank by the submersible pump flows inside the first liquid outlet pipe and the first liquid inlet pipe which are arranged obliquely downward, avoiding the leakage of the insulating oil from the gap between the two due to backflow.

[0007] Specifically, a second liquid outlet pipe is fixedly connected to the lower part of one side of the transformer. A second oil outlet nozzle is provided at one end of the second liquid outlet pipe away from the transformer.

[0008] Specifically, the submersible oil pump is fixedly installed at the top of the fuel tank. One side of the fuel tank is fixedly connected with a second sleeve. A first sliding groove is formed inside the second sleeve for the second liquid inlet pipe to be slidably installed. The second liquid inlet pipe is movably inserted into one end of the second sleeve away from the fuel tank.

[0009] Specifically, a first slot is provided inside the second liquid inlet pipe for the second oil outlet nozzle to be inserted.

[0010] By adopting the above technical solution, through the slidably installed first liquid inlet pipe and second liquid inlet pipe, the connection between the first liquid inlet pipe and the first liquid outlet pipe, and between the second liquid inlet pipe and the second liquid outlet pipe can be made more convenient, so as to achieve a quick connection method.

[0011] Specifically, a flow meter is provided at the top of the submersible oil pump. A suction oil pipe is fixedly connected to the bottom of the submersible oil pump, and the suction oil pipe is arranged inside the fuel tank.

[0012] By adopting the above technical solution, the submersible oil pump can transport the insulating oil in the fuel tank into the transformer through the suction oil pipe, and the flow meter can observe the oil output of the submersible oil pump.

[0013] Advantages of the present utility model:

[0014] (1) For the novel energy-efficient submersible oil transformer of the present utility model, the insulating oil pumped out from the fuel tank by the submersible oil pump flows inside the first liquid outlet pipe and the first liquid inlet pipe arranged obliquely downward, avoiding the leakage of the insulating oil from the gap between the two due to backflow.

[0015] (2) For the novel energy-efficient submersible oil transformer of the present utility model, through the slidably installed first liquid inlet pipe and second liquid inlet pipe, the connection between the first liquid inlet pipe and the first liquid outlet pipe, and between the second liquid inlet pipe and the second liquid outlet pipe can be made more convenient, so as to achieve a quick connection method.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] In order to avoid oil leakage, this problem is circumvented by improving the connection between the submersible oil pump and the transformer. As an embodiment of the present utility model, as Figures 1 - 3 shown, a high-efficiency and energy-saving new submersible transformer described in the present utility model includes a transformer 1 and a submersible oil pump 6. One upper side of the transformer 1 is fixedly connected with a first sleeve 2. A second chute 16 is provided inside the first sleeve 2 for slidably installing a first liquid inlet pipe 3. The first liquid inlet pipe 3 is movably inserted into one end of the first sleeve 2 away from the transformer 1. A second slot 15 is provided inside the first liquid inlet pipe 3. One side of the submersible oil pump 6 is fixedly connected with a first liquid outlet pipe 4. One end of the first liquid outlet pipe 4 away from the submersible oil pump 6 is provided with a first oil nozzle 12. The first oil nozzle 12 is inserted into the second slot 15.

[0023] During use, place the oil tank 7 equipped with the submersible oil pump 6 beside the transformer 1, align the first oil nozzle 12 connected to the first liquid outlet pipe 4 with the second slot 15 inside the first liquid inlet pipe 3, and then through the sliding of the first liquid inlet pipe 3 in the first sleeve 2, make the first liquid inlet pipe 3 close to the first liquid outlet pipe 4, and at the same time make the first oil nozzle 12 of the first liquid outlet pipe 4 able to be inserted into the second slot 15 inside the first liquid inlet pipe 3, and fixedly connect one end of the first liquid outlet pipe 4 and one end of the first liquid inlet pipe 3 through a flange.

[0024] It should be noted that the connection between the first liquid inlet pipe 3 and the first liquid outlet pipe 4 is set to be inclined downward, which can avoid the reverse flow of insulating oil and prevent oil leakage.

[0025] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that a second liquid outlet pipe 10 is fixedly connected to one lower side of the transformer 1. One end of the second liquid outlet pipe 10 away from the transformer 1 is provided with a second oil nozzle 17.

[0026] Exemplarily, as Figures 1 - 3As shown, the present utility model further includes that the submersible oil pump 6 is fixedly installed at the top of the oil tank 7. One side of the oil tank 7 is fixedly connected with a second sleeve 8. A first sliding groove 14 is formed inside the second sleeve 8 for the second liquid inlet pipe 9 to be slidably installed. The second liquid inlet pipe 9 is movably inserted into one end of the second sleeve 8 away from the oil tank 7.

[0027] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that a first slot 13 is provided inside the second liquid inlet pipe 9 for the second oil outlet nozzle 17 to be inserted.

[0028] During use, first align the second oil outlet nozzle 17 of the second liquid outlet pipe 10 with the first slot 13 inside the second liquid inlet pipe 9. By sliding the second liquid inlet pipe 9 in the second sleeve 8, make the second liquid inlet pipe 9 approach the second liquid outlet pipe 10, and at the same time enable the second oil outlet nozzle 17 of the second liquid outlet pipe 10 to be inserted into the first slot 13 inside the second liquid inlet pipe 9, and fixedly connect one end of the second liquid outlet pipe 10 with one end of the second liquid inlet pipe 9 through a flange.

[0029] It should be noted that the connection between the second liquid inlet pipe 9 and the second liquid outlet pipe 10 is set to be inclined downward, which can avoid the phenomenon of insulating oil flowing back and leaking.

[0030] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that a flow meter 5 is provided at the top of the submersible oil pump 6. The bottom end of the submersible oil pump 6 is fixedly connected with an oil suction pipe 11, and the oil suction pipe 11 is arranged inside the oil tank 7.

[0031] During use, the submersible oil pump 6 can transport the insulating oil in the oil tank 7 into the transformer 1 through the oil suction pipe 11, and the flow meter 5 can observe the oil output of the submersible oil pump 5.

[0032] When the utility model is in use, first place the fuel tank 7 equipped with the submersible oil pump 6 beside the transformer 1, align the first oil outlet nozzle 12 connected to the first liquid outlet pipe 4 with the second slot 15 in the first liquid inlet pipe 3, and align the second oil outlet nozzle 17 of the second liquid outlet pipe 10 with the first slot 13 in the second liquid inlet pipe 9. Then, by sliding the first liquid inlet pipe 3 in the first sleeve 2, make the first liquid inlet pipe 3 approach the first liquid outlet pipe 4, and at the same time make the first oil outlet nozzle 12 of the first liquid outlet pipe 4 be able to insert into the second slot 15 in the first liquid inlet pipe 3, and fixedly connect one end of the first liquid outlet pipe 4 to one end of the first liquid inlet pipe 3 through a flange. Subsequently, by sliding the second liquid inlet pipe 9 in the second sleeve 8, make the second liquid inlet pipe 9 approach the second liquid outlet pipe 10, and at the same time make the second oil outlet nozzle 17 of the second liquid outlet pipe 10 be able to insert into the first slot 13 in the second liquid inlet pipe 9, and fixedly connect one end of the second liquid outlet pipe 10 to one end of the second liquid inlet pipe 9 through a flange. The submersible oil pump 6 will transport the insulating oil in the fuel tank 7 from the first liquid outlet pipe 4 into the first liquid inlet pipe 3 through the oil suction pipe 11, and then flow into the transformer 1 through the first liquid inlet pipe 3. The oil after circulation inside the transformer 1 will be transported into the second liquid inlet pipe 9 again through the second liquid outlet pipe 10, and then flow into the fuel tank 7 through the second liquid inlet pipe 9, forming a cycle.
