Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer structure with dust-proof, waterproof and earthquake-resistant functions. Background Art

[0002] A transformer is a static electrical appliance that converts alternating current electrical energy of one voltage level into alternating current electrical energy of another voltage level of the same frequency by electromagnetic induction between coils, utilizing the law of electromagnetic induction. Its conversion principle is as follows: when the primary coil of the transformer is connected to an alternating current power supply, an alternating magnetic flux is generated in the iron core. This alternating magnetic flux will generate an induced electromotive force in the secondary coil, thereby achieving voltage conversion.

[0003] Specifically, a conventional transformer mainly consists of a primary coil, also known as the original coil, a secondary coil, also known as the secondary coil, and an iron core, also known as a magnetic core. With the popularization of the application fields of transformers, some usage requirements in harsh environments such as high temperature, humidity, rain, and water immersion have put forward higher design standards for transformers. For example, transformers used in ships, electric vehicles, or multiple unit trains. Thus, waterproof transformers have emerged. Waterproof transformers usually adopt a sealed structure to completely isolate key components such as the oil tank, oil pump, and windings to prevent oil from contacting the outside air. At the same time, the internal transformer is subjected to potting treatment, generally using thermally conductive epoxy resin as the potting material to improve insulation performance and heat dissipation performance.

[0004] Based on this, Chinese Patent CN113707414B discloses a transformer with dust-proof and waterproof effects, which includes a left shell, a right shell, and an inner frame. The left shell and the right shell are fixed by clamping. The inner frame is arranged inside the left shell and the right shell, and a winding frame is arranged inside the inner frame. Through the arranged left shell, right shell, and inner frame, in cooperation with the rubber strip structure, the user can wind the coil inside the winding frame. First, the water absorption plate on one side of the inner frame absorbs the liquid entering the left shell and the right shell, and the heat absorption material inside the inner frame can also absorb the heat generated by the coil to avoid the phenomenon of high temperature. The water absorption plate structure can improve the internal waterproof performance and increase the service life. Through the arranged rubber strip structure, the user can avoid liquid entering from different directions through the different opening directions of the left shell, right shell, and inner frame. The internal rubber strip can form a barrier to block liquid from entering the interior after the left shell and the right shell are clamped.

[0005] However, the above-disclosed transformer still has the technical problem of insufficient seismic performance. Specifically, although the existing patent reveals a housing design structure of a transformer with dust-proof and waterproof effects, it does not disclose the internal layout of the core structure of the transformer within the housing, such as the skeleton and windings. Due to the requirements of the transformer's usage scenarios, the transformer sometimes undergoes sudden impacts. If at this time, the coils, skeletons, etc. inside the housing become loose after being impacted, it will cause fluctuations in the voltage transformation performance of the transformer. In addition, there are also technical solutions in the prior art that use potting glue or other media inside the housing to completely cover components such as coils and skeletons. However, after this kind of encapsulation, it is difficult to disassemble each component, which is particularly inconvenient in some usage scenarios that require disassembly and maintenance.
