AI Technical Summary
During the heat dissipation process, existing transformers are prone to allow dust to enter the protection box, resulting in short circuits, corrosion and signal quality deterioration, and poor dust protection effect.
A fully enclosed dust-proof transformer is designed to prevent dust through the sealing cover of the shell and the heat dissipation fins. At the same time, the oil circulation system is used to cool down. The oil flows through the injection pipe and removes heat in the shell and filters impurities through the filter.
It realizes effective prevention of dust, protects internal devices, and quickly cools down through the oil circulation system to avoid damage to the transformer body due to high temperatures, improving the safety of equipment usage and signal quality.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transformers, and particularly relates to a dust-proof transformer. Background Art
[0002] Many existing protective boxes of transformers are provided with heat dissipation holes for heat dissipation, making it easy for external dust to enter the interior of the protective box from the heat dissipation holes. Dust generally contains elements such as Cl, S, Fe, Zn, etc. The Cl and S elements contained in the dust exist in the form of chloride ions, sulfate ions, etc., and will conduct electricity under the condition of moisture absorption, forming a short circuit or causing corrosion of devices and single boards; the dust also contains a small amount of metal elements such as Fe and Zn, which will also cause very small short circuits. At the same time, if there is a lot of dust, it can cause electrostatic adsorption, resulting in poor contact between metal connectors or metal contacts inside the device and deterioration of signal quality. Whether it is a short circuit or poor contact will lead to circuit failures. At the same time, it should be particularly noted that some transformers are provided with a filter net on the shell to ensure heat dissipation, but it is very difficult to ensure that dust does not enter the shell during the replacement of the filter net or during long-term use. Therefore, how to improve the dust-proof effect of the transformer to improve the use safety of the transformer is an urgent problem to be solved. Summary of the Invention
[0003] In order to solve the technical problems of poor dust-proof and heat dissipation effects of transformers in the prior art, the present invention provides a dust-proof transformer.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a dust-proof transformer, including a support base, a shell is installed on the top of the support base, an oil tank is installed in the support base, an oil outlet of the oil tank is connected to a second oil pipe, the second oil pipe is a continuously bent pipeline, a fan is installed on the top side of the oil tank, the fan is located directly above the second oil pipe, an oil outlet of the second oil pipe is connected to an oil pump, an oil outlet of the oil pump is connected to a third oil pipe, the third oil pipe is also communicated with a main pipe, the main pipe is fixed at the bottom of the shell, and the main pipe is communicated with a plurality of F-shaped spray oil pipes located inside the shell; an oil inlet of the oil tank is communicated with the shell through a first oil pipe, and a filter is installed on a pipe section of the first oil pipe; a horizontally arranged mounting plate is fixed inside the shell through a vertically arranged support rod, and a transformer body is installed on the top of the mounting plate; heat dissipation fins are arranged on both sides of the shell; a sealing cover is also installed on the top of the shell.
[0005] Working principle: The housing of the present invention is a fully enclosed structure, which can avoid the problem that dust enters through heat dissipation holes in the traditional transformer housing and affects the operation of the transformer; through the detachable sealing cover provided, it is convenient to maintain the transformer body; the housing can dissipate heat through heat dissipation fins; the oil pump pumps oil from the oil tank through the second oil pipe, and successively passes through the third oil pipe, the main pipe, the spray oil pipe and is sprayed in the housing by the spray oil pipe. The oil sprayed by the spray oil pipe can drive the oil inside the housing to flow in a fixed direction, so that the oil can quickly flow through the transformer body, thereby taking away the heat on the transformer body and achieving a good cooling effect. Therefore, while achieving airtightness, it also has a good cooling effect. Finally, the oil passes through the first oil pipe and flows through the filter to avoid the influence of impurities on the transformer body, and finally flows into the oil tank. The hot oil dissipates heat through the wall of the continuously bent second oil pipe, and at the same time, the heat dissipation efficiency is accelerated under the blowing of the fan.
[0006] Compared with the prior art, the present invention has the following beneficial effects:
[0007] The dust-proof transformer of the present invention is a fully enclosed structure, which effectively prevents dust from entering and has a good protective effect on internal components. At the same time, through oil circulation, the transformer body can be quickly cooled down, avoiding damage to the transformer body caused by high temperature, and having good protection.

Detailed implementation manners
[0013] The following further illustrates the present invention in conjunction with specific embodiments. Embodiment
[0014] Such as Figure 1As shown, a dustproof transformer comprises a support base 9, a shell 1 is installed on the top of the support base 9, an oil tank 8 is installed in the support base 9, the oil outlet of the oil tank 8 is connected to a second oil pipe 7, the second oil pipe 7 is a continuously bent pipeline, a fan 19 is installed on the top side of the oil tank 8, the fan 19 is located directly above the second oil pipe 7, the oil outlet of the second oil pipe 7 is connected to an oil pump 6, the oil outlet of the oil pump 6 is connected to a third oil pipe 5, the third oil pipe 5 is also connected to a main pipe 4, the main pipe 4 is fixed at the bottom of the shell 1, and the main pipe 4 is connected to a plurality of F-shaped oil injection pipes 15 located inside the shell 1, as shown in FIG. Figure 2 As shown; the oil inlet of the oil tank 8 is connected to the shell 1 through the first oil pipe 12, and a filter 11 is installed on the pipe section of the first oil pipe 12; the interior of the shell 1 is fixed with a horizontally arranged mounting plate 17 through a vertically arranged support rod 18, and a transformer body 16 is installed on the top of the mounting plate 17; heat dissipation fins 3 are arranged on both sides of the shell 1; and a sealing cover 14 is also installed on the top of the shell 1.
[0015] Further, such as Figure 1 As shown, two shut-off valves 10 are also installed on the pipe section of the first oil pipe 12, and the two shut-off valves 10 are respectively located on both sides of the filter 11. The two shut-off valves 10 can be used to maintain or replace the filter under the shut-off condition, which is convenient for continuous use.
