Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a short-circuit-resistant transformer with side auxiliary fastening installation. Background Art

[0002] Anti-short-circuit transformers are devices that use electromagnetic induction to block, transform and match AC voltage. They are widely used in agriculture, industry and transportation. They have coils inside and realize voltage control through the movement of the coils. Transformer failures include circuit failures, winding failures, transformer oil leakage and joint failures, among which circuit failures are mostly short-circuit failures. In order to prevent economic losses caused by transformer short-circuit, anti-short-circuit transformers have appeared on the market.

[0003] For example, the invention with the authorization announcement number CN106373756A particularly relates to a short-circuit resistant transformer and its preparation process. The short-circuit resistant transformer includes an A-phase coil, a B-phase coil, and a C-phase coil, each including an iron core, a low-voltage coil, and a high-voltage coil. The low-voltage coil and the high-voltage coil are sleeved outside the iron core, and the inner insulating cardboard, the low-voltage coil conductor, the interlayer insulation, and the end ring are an integral structure. The conductor, interlayer insulation, and end ring of the high-voltage coil are an integral structure. Pads and clamps are arranged outside the end rings of the low-voltage coil and the high-voltage coil in sequence. The low-voltage coil, the high-voltage coil, and the iron core are supported by round wooden sticks. The gaps between the A-phase coil, the B-phase coil, and the C-phase coil are supported by support plates. Insulating plates are arranged outside the A-phase coil and the C-phase coil at both ends, and the insulating plates are connected to the clamps by top nails. This solution enables the distribution transformer to meet the short-circuit resistant capability without increasing the cost of raw materials, effectively preventing the transformer winding from becoming unstable and deforming during a short circuit, and creating more profit space for manufacturers;
