Single-winding current transformer for metering and measuring

A single-winding current transformer for metering and measuring comprises a base body, a protective cover, fillister head screws with sealing holes and a base board, wherein an ultracrystalline alloy block is fixedly installed in a protective shell body, and a secondary winding is wound outside the shell body. A connection board is welded with a wiring board, and a machine body is formed by winding of a primary winding and external insulation buffering and shield wrapping of coils. Vacuum pouring by red epoxy resin mixture is carried out to the machine body, round head setting-in nuts and a setting-in nut to enable the base body to be formed. A totally closed support type whole body is formed by final assembly of the base body, the protective cover, the fillister head screws with the sealing holes and the base board according to structures. According to the single-winding current transformer for metering and measuring, technology of ultracrystalline alloy is adopted in the secondary winding, the surface of th
