Description

Heat dissipation protection shell for transformer

technical field

The invention relates to a heat dissipation protection shell for a transformer, which belongs to the technical field of electric equipment.

Background technique

Transformers are the basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are a primary coil, a secondary coil and an iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for raising and lowering voltage, matching impedance, safety isolation, etc. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a stationary coil, an electric potential is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux intersecting with the coil changes, which is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.

The main functions of transformers are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc., and can be divided into power transformers and special transformers according to their uses.

Existing transformer shells generally do not have a structure specially designed to improve heat dissipation efficiency. However, due to structural reasons, the heat dissipation effect of existing transformer protective shell devices is not particularly good, and it is likely to cause irreversible damage to the internal coils. Often, due to slow heat dissipation, the transformer is damaged due to excessive temperature, or even burns and explodes, resulting in large-area power outages, fire accidents, etc., easily causing loss of public property, and even explosions in severe cases, posing a threat to people's life and property safety.

The patent publication number is CN105428009A, which relates to a transformer protective casing and a transformer device using the casing. The protective shell of the transformer includes a side wall, and the shell wall formed by any side of the side wall is detachably fixed on the adjacent shell wall through a plug-in fixing structure. The plug-in fixing structure includes a jack structure and a latch structure respectively fixed at the joint of the two shell walls. Threaded fasteners and connecting flanges can position two adjacent shell walls, while the pin structure and jack structure can be easily disassembled and installed while positioning and connecting, and are not easy to loosen. Cooperating with threaded fasteners can realize firm connection and quick disassembly, which is convenient for handling, installation and maintenance, and can effectively improve work efficiency.

The patent publication is preferably CN204257325U, which discloses a noise-reducing installation structure for a dry-type transformer housing, which includes a housing body installed on the ground of the substation room and a transformer mounting base. A groove matching the corresponding boss is provided on the outer wall, and the transformer installation base is installed in the lower opening of the housing body in such a way that each boss is snapped into the corresponding groove, and a shock-absorbing rubber pad is arranged between each boss and the corresponding groove. The noise-reducing installation structure of the utility model can effectively reduce the noise of the dry-type transformer.

Although the above two patents provide the protection object of the transformer, neither of them solves the problem of heat dissipation of the transformer.
