专利汇可以提供Dry type transformer专利检索,专利查询,专利分析的服务。并且PURPOSE:To remarkably reduce the working steps (man-hours) in forming an insulation layer by supplying an insulator to the clearance between an insulation cylinder where a metal shield is attached to the interior thereof and an internal coil and by hardening it. CONSTITUTION:An insulation cylinder 6 where a metal shield 3 is attached to the internal surface with an adequate interval is arranged at the external circumference of an internal coil 1 concentrically arranged to an external coil and the varnish or resin insulator is supplied to the clearance between the internal coil 1 and insulation cylinder 6 and then it is hardened. Moreover, a bottom plate 7 which prevents flow of insulator is also provided. With such a structure, insulation between the internal coil 1 and metal shield 3 is ensured by the insulator 5 supplied and hardened, while insulation at the outside of metal shield 3 is ensured by the insulation cylinder 6.,下面是Dry type transformer专利的具体信息内容。
