Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a protective cover. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In the 19th century, with the emergence of electricity applications and the need for long-distance power transmission, people began to explore voltage change technology. Its theoretical basis originated from the law of electromagnetic induction discovered by Faraday. On this basis, scientists wound coils with different numbers of turns on the iron core, thus creating the prototype of the transformer. It was originally intended to solve the problem of voltage rise and fall in power transmission to reduce energy loss in transmission lines. Later, with the continuous development of materials, structural design and other aspects, its performance and application range have been greatly expanded. From the early simple voltage conversion equipment, it has gradually developed into a key electrical equipment widely used in power system transmission, distribution, electronic equipment, industry, transportation, new energy and other fields.

[0003] However, the following problems still exist in the prior art:

[0004] Insufficient protection performance. The existing transformer casing has poor protection performance when facing complex operating environments. For example, in industrial environments with dust, water vapor, and corrosive gases, or in outdoor scenarios where it is susceptible to wind, rain, and impact from foreign objects, the transformer casing may not be able to effectively resist the invasion of these external factors, which may easily cause damage to important components such as the primary coil, secondary coil, and iron core inside the transformer, affecting the normal operation and service life of the transformer.

[0005] The heat dissipation method is single. Most existing transformers do not have the function of automatically adjusting heat dissipation according to actual temperature conditions. They cannot adjust the heat dissipation strategy in real time according to the working status of the transformer and the ambient temperature, resulting in insufficient heat dissipation in some cases and excessive heat dissipation in other cases, wasting energy.

[0006] Installation and maintenance are inconvenient. When performing maintenance and inspection on transformers, the structural design of existing transformers may not be convenient for workers to operate. For example, the outer casing of some transformers is difficult to disassemble, and the layout of internal components is unreasonable, which makes it difficult for workers to access the parts that need to be inspected during maintenance, increasing the time and difficulty of maintenance.

[0007] In this regard, in order to solve this technical problem, the present application proposes a transformer with a protective cover. Utility Model Content

[0008] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a transformer with a protective cover. The transformer has excellent protection performance and can effectively block external factors such as dust, water vapor, foreign matter, etc. to prevent them from entering the interior of the transformer. At the same time, it realizes efficient heat dissipation and ventilation design, which can avoid local overheating, effectively improve the operating efficiency and stability of the transformer, and reduce the problem of dust entry caused by excessive ventilation.
