The present invention relates to a boltless clamp transformer manufactured by a method of manufacturing a columnar, ground type impregnated, boltless clamp transformer, and more particularly, to boltless clamp assembling with a bolt when assembling a winding and a core in transformer manufacturing. It relates to a transformer composed of no impregnation and no bolt by assembling and assembling to fix it firmly with a steel strip.

In general, in the case of the transformer technique, the winding and core were assembled by varnish-impregnating the windings in the manufacture of the transformer and bolting the bolts when assembling the cores.

 Since the short circuit strength is weak when manufacturing transformers in this way, varnish impregnation is performed to reinforce the mechanical strength while knowing that there are problems such as deterioration of quality and productivity, generation of industrial waste, and reduction of insulation effect for short circuit strengthening.

 As a result, problems such as the creation of empty spaces in the windings during varnish impregnation, increased possibility of incorporation of metallic materials, impedement of cooling of insulating oil, long time to manufacture windings, difficulty in determining and maintaining standard processes, environmental pollution, and industrial waste generation There are disadvantages.

In addition, the work environment is vulnerable in the manufacturing process, there is a problem that harms the health of workers. Insulation of oil cooling, restriction of circulation of oil through the flow path, heating of oil heated at the hottest point is not smooth (promoting thermal deterioration of oil and paper), and the average winding temperature difference between impregnated winding and impregnated winding about 2 to 5 ° The difference is large depending on the degree of impregnation with C.

In addition, it takes a long time to produce the transformer, and is produced by the process of winding manufacturing → drying → varnish impregnation → drying → frame assembly → drying → frame refastening → transformer assembly → test-finished product (which takes a long time by varnish impregnation and drying again).

The present invention was devised to solve the above problems, an object of the present invention is to produce a non-impregnation without varnish impregnation when assembling a transformer and to assemble the clamp of the bolt without reinforcement as a method of assembling to strengthen the fixing force Its purpose is to provide a transformer consisting of impregnation- and bolt-free, which is made and equipped with a corpse.
