Abstract
A low-partial-discharge high-capacity post type current transformer comprises a housing, a core, a conducting rod, a secondary coil composed of a measuring level coil and a protective level coil, a first junction board, and a second junction board. The measuring level coil and the protective level coil are both wound on the core and are isolated by an insulating paperboard. The conducting rod penetrates the measuring level coil and the protective level coil. One end of the conducting rod is connected with a first connecting board vertically arranged; the other end of the conducting rod is connected with a second connecting board vertically arranged. The first and second junction boards are horizontally arranged. The left end of the first junction board is connected with the upper end of the first connecting board; the right end of the second junction board is connected with the upper end of the second connecting board. First and second shield boards are arranged below the lower ends of the first and second junction boards respectively. wires led out of two ends of the measuring level coil and the protective level coil are connected with corresponding connecting terminals inside a secondary coil junction box on the lower portion of the outer wall of the housing, respectively. The low-partial-discharge high-capacity post type current transformer has the advantages of low partial discharge, high capacity, operational stability and high safety.
