Dry-type transformer stable in bearing

Abstract

The invention discloses a dry-type transformer stable in bearing. The dry-type transformer comprises ventilation cavity plates, channel steels and seat boxes. The number of the ventilation cavity plates is two, the two ventilation cavity plates are oppositely and transversely arranged, induced draft fans are arranged in openings in the ends of the two ventilation cavity plates, the two ventilation cavity plates are provided with vertical iron cores in parallel, the outer sides of the iron cores are sleeved with low-voltage coils and high-voltage coils, and annular ventilation air channels are formed between the low-voltage coils and the high-voltage coils; the channel steels are fixed on one sides, opposite to the iron core, of the ventilation cavity plates, the end parts of the two channel steels on the same side are connected through a clamping piece, and the middle parts of the two channel steels on the same side are supported through a supporting piece; and the seat boxes are arranged in the mounting holes in the side faces of the ventilation cavity plates, and the seat boxes correspond to the ends of the high-voltage coils one to one and support the high-voltage coils. According to the dry-type transformer stable in bearing, the overall stability is improved, a main body part of the dry-type transformer is stably supported, and meanwhile the influence of vibration on loading is effectively weakened.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a dry-type transformer with stable load. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. The iron core is mainly composed of silicon steel sheets. Composed of coils cast with epoxy resin, an insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coils are supported and restrained by pads. Larger weight, its load is not stable, and it is easy to generate vibration. Therefore, we propose a dry-type transformer with stable load. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects, provide a dry-ty...
