Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a low energy consumption transformer. Background Art

[0002] Patent application No. 202220126062.7 discloses a low-energy dry-type transformer, including an iron core coil insulation coating, an outer shell, a heat dissipation mechanism and an air guide assembly, etc. The spiral air guide member of the air guide assembly and the elastic cotton separate the internal space of the outer shell to form a spiral air duct. When the heat dissipation fan is working, the air with a lower external temperature is introduced into the fan shell from the air inlet at the bottom of the fan shell and blown into the outer shell. The spiral air duct extends the flow path of the airflow, so that the airflow with a lower temperature can be in contact with the iron core coil insulation coating. The outer shell is fully in contact with the outer shell, thereby improving the heat dissipation effect and preventing heat accumulation from damaging the transformer under long-term load. It has the effects of good heat dissipation effect and low energy consumption. An annular strip is arranged on the bottom surface of the pressure ring, and an annular groove matched with the annular strip is arranged on the top surface of the outer shell. When the heat dissipation fan is turned off, the diaphragm has a certain elastic restoring force, so that the annular strip on the lower surface of the pressure ring can be aligned with the annular groove up and down, and then pressed into the annular groove to close the top opening of the outer shell, thereby preventing external dust from entering the air duct and adhering to the insulating sheath of the core coil.

[0003] The above disclosed technical solution still has the following defects. Firstly, after the air guide component extends the airflow path, the airflow heats up quickly from bottom to top. The heated airflow cannot effectively dissipate heat to the upper part of the transformer. The lower part of the transformer needs to be gradually cooled down before the airflow can no longer be heated. The upward airflow can dissipate heat to the upper part of the transformer, resulting in the phenomenon that the upper part of the transformer cannot dissipate heat in time. Secondly, the transformer generates less heat during daily operation, which can be discharged directly from the opening of the casing without a fan. However, the elastic membrane group will close the top opening of the casing after the fan stops, resulting in this part of the heat being unable to be discharged. The transformer can only rely on the fan to dissipate heat, which causes the fan to run for a long time and the required energy consumption to increase.

[0004] Therefore, based on the above-mentioned defects, it is necessary to make partial improvements to the disclosed technical structure. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a low-energy consumption transformer, which uses multiple heat dissipation cavities to allow airflow to dissipate heat in each heat dissipation cavity, so that while the airflow fully contacts the insulating sheath of the core coil for heat dissipation, it can also dissipate heat in various areas of the transformer at the same time, avoiding the phenomenon that the upper part of the transformer cannot be cooled in time. When the fan is not in use, the airflow gathered from the outside can enter the heat dissipation cavity to dissipate less heat generated by the daily operation of the transformer, avoiding the phenomenon of relying solely on the fan for heat dissipation and reducing the required energy consumption.

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

[0007] A low energy consumption transformer comprises an iron core coil insulation covering body, the outer part of the iron core coil insulation covering body is sleeved with a shell, an air guide is arranged between the shell and the iron core coil insulation covering body, the top and bottom of the shell are both in a closed state, a plurality of baffles are fixedly sleeved on the outer side of the iron core coil insulation covering body, the outer side of the baffles is fixedly connected to the inner wall of the shell, the plurality of baffles divide the interior of the shell into a plurality of heat dissipation chambers, the number of the air guides is plurality and they are distributed in each heat dissipation chamber, a fan is fixedly connected to one side of the shell, an air duct is connected at the air outlet of the fan, the air duct is connected to each heat dissipation chamber respectively through a plurality of branch pipes, and the branch pipes are located below the heat dissipation chamber, a heat dissipation port located above each heat dissipation chamber is provided on the other side of the shell, and a hood is connected at the heat dissipation port, an opening is provided on the side of the hood away from the shell, and the size of the hood opening gradually increases in the direction away from the shell.

[0008] Furthermore, a regulating valve is installed on the branch pipe.

[0009] Furthermore, a dustproof net is installed at the opening of the wind cover.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. First, through multiple heat dissipation cavities, the airflow dissipates heat in each heat dissipation cavity, and then the airflow fully contacts the insulation coating of the core coil to dissipate heat, and at the same time, various areas of the transformer can dissipate heat at the same time, avoiding the phenomenon that the upper part of the transformer cannot dissipate heat in time.

[0012] 2. Secondly, through multiple wind hoods, hot air is discharged from different areas of the shell, and the hot air is diffused and discharged from the gradually increasing openings of the wind hoods, that is, the heat is retained and will not be discharged from one place. The gradually increasing openings can also gather the external airflow into the heat dissipation cavity when the fan is not in use, and dissipate less heat generated by the daily operation of the transformer, avoiding the phenomenon of relying solely on the fan for heat dissipation and reducing the required energy consumption.

[0013] 3. The airflow into each branch pipe is made the same by adjusting the valve, so as to avoid the phenomenon that most of the airflow generated by the fan is discharged preferentially from the branch pipe close to the fan, thus ensuring the heat dissipation effect in each heat dissipation cavity and preventing external dust from adhering to the insulation coating of the core coil through the dustproof net.

[0022] Working principle: It should be noted that, in the present utility model, only partial improvements are made to the disclosed patent structure, and the original air guide 3 structure is still composed of the spiral partition and elastic cotton in the disclosed technology. When the fan 6 is used to dissipate heat to the iron core coil insulation coating 1, the fan 6 is started to blow the air flow into the air duct 7, and then enters each heat dissipation cavity 5 from the branch pipe 8. The air flow entering the heat dissipation cavity 5 contacts with part of the iron core coil insulation coating 1 in the heat dissipation cavity 5 along the spiral air duct formed by the air guide 3 to cool down, and then flows upward. During operation, the heat generated by the core coil insulation coating 1 is discharged from the shell 2 through the wind hood 9 corresponding to the heat dissipation cavity 5 and diffused along the gradually increasing opening of the wind hood 9, so that the core coil insulation coating 1 is located in the area of ​​each heat dissipation cavity 5, and the heat can be dissipated at the same time. When the transformer generates less heat during daily operation and the fan 6 is not needed, the external airflow is collected from the larger opening of the wind hood 9, passes through the dustproof net 11 to filter the dust, and then enters each heat dissipation cavity 5 to cool the core coil insulation coating 1.
