   Dry type transformer It can be customized now. Dry type transformer The size and many parts can be assembled, just like a computer. Dry type transformer There are many problems to be noticed in the process of assembly. Usually, there are some technical requirements. What are the related technologies for dry type transformer assembly?

 Dry type transformer

Background technology:

Dry-type transformer is a transformer that does not assemble fuel tank and put iron core and coil in air. It is usually applied to local lighting, high-rise buildings, airports, wharves and so on. Because of the absence of insulating oil, dry transformers require higher insulation and heat dissipation for their structures.

Technology realization elements:

The technical problem to be solved by the invention is to provide an improved dry type transformer and its assembling method, which can solve the insufficiency of the existing technology and improve the insulation and heat dissipation performance of the dry type transformer. In order to solve the above technical problems, the technical proposal adopted by the invention is as follows. An improved dry type transformer comprises a base, and a high side iron core and a low-pressure side iron core are fixedly arranged on the base, and a high-pressure side skeleton is arranged outside the iron core of the high voltage side. A low-voltage side skeleton is arranged outside the iron core of the low-pressure side, and a high voltage side coil and a low-voltage side coil are wound outside the high voltage side skeleton and the low pressure side frame, respectively, and the outer side of the high voltage side coil and the low-voltage side coil are respectively arranged. An insulating layer is arranged between the high voltage side of the transformer and the low pressure side, the insulating layer is fixed on the base, and the upper part of the base is provided with a shell, and the inner side of the housing is provided with a thermal conductive adhesive layer. As a preferred one, a plurality of grooves are evenly arranged on the high pressure side skeleton, and a plurality of insulating rubber pads are arranged in the groove, and a baffle plate is arranged on the outer side of each groove. A plurality of through holes are evenly arranged on the skeleton of the low pressure side, and an installation position is arranged between the two adjacent through-holes, and a connecting ball head is arranged in the installation position, and a limited position plate is connected to the connecting ball head. A buffer layer is filled between the limiting plate and the mounting position, and a binding belt is sleeved between the adjacent two through holes. As a preferred, the supporting frame is arranged inside the high-pressure side skeleton, and the reinforcing wall is connected with the side frame of the supporting column, and the bottom of the supporting column is connected with the base through the counterweight block. The second supporting columns are arranged inside the low side frame, and the second reinforcing bars connected with the low side skeleton are arranged on the side walls of the second supporting columns, and the bottom of the second supporting columns is matched by second parts. The heavy block is connected with the pedestal, and a pipe with a counterweight block and a second counterweight block is arranged in the base, and a connecting rod connecting the counterweight block and the second counterweight block is arranged in the pipeline. As an optimization, the insulating layer comprises the following components of weight, 230~250 aramid fibers, 75~100 dicyclopentadiene resins, 15~20 alkyl methacrylate, 2~3 nitrogen nitrogen two methylformamide, 5~10 butene two anhydride, 3~5 3~5 phosphoric acid three butyl, 10~15 parts of hydroxymethyl cellulose sodium, 10~20 salicylic acid propyl ester, 10~20 parts. Benzyl two methyl silane and 2~6 3,5- two hydroxy acetophenone. As a preferred one, the thermal conductive adhesive layer comprises the following components of weight fraction, 180~210 parts of methyl vinyl silicone rubber, 100~130 parts of neoprene, 20~25 carbon black, 15~25 alkyl amine alcohols, 5~12 4- hydroxy -4- methyl -2- amyl ketone, 30~40 fractions of nanometer grade silicon dioxide, 3~5 parts of sodium tripolyphosphate, 5~6 parts 2, 6 ditert butylcresol, 1~3 2,6- two methyl morpholine, 2~6 pentaerythritol, 3~5 phthalic acid two octyl ester, 7~10 2,3,5- three methyl phenol, 10~15 fraction of O-benzyl two carboxylic acid bicyclic ester. An improved method for assembling a dry type transformer comprises the following steps: A, placing the base on the operation frame, adjusting the level; B, installing the iron core on the high voltage side and the low-side iron core through the clamping rack on the base respectively; and C, respectively, winding the high voltage side coil and the low voltage side coil on the high voltage side skeleton and the low-voltage side skeleton respectively; D, connect the skeleton of the high pressure side and the low side skeleton to the core of the high voltage side and the iron core of the low pressure side respectively, then adjust the center of gravity of the base to the center of the base by tightening and binding the high voltage side coil and the low-voltage side coil; E, install the insulating layer at the center of the base;

These are the main assembly technologies and common methods of assembly of dry type transformers for reference. If you have any other questions about other assembly methods of dry transformers, please pay attention to our website.
