Abstract

The present invention relates to a three-phase integrated current transformer, which comprises a housing. Inside the housing, there are provided an annular first iron core, a second iron core and a third iron core. On the housing, there are provided three copper bar channels arranged side by side, and the three copper bar channels respectively pass through the middle parts of the first iron core, the second iron core and the third iron core; both ends of the copper bar channels are open on the opposite first side wall and second side wall of the housing; the second iron core is arranged adjacent to the first side wall, the first iron core and the third iron core are arranged adjacent to the second side wall, and the first iron core, the second iron core and the third iron core are arranged in a "pin" shape; copper bar fixing modules are arranged in both of the two copper bar channels corresponding to the first iron core and the third iron core, and the copper bar fixing modules are arranged adjacent to the first side wall; on the second side wall, there is provided a network cable socket matching the outer contour of the network cable plug, and the network cable socket is located between the first iron core and the third iron core. The structure is reasonable, and the appearance of the current transformer is simple. It is not only convenient for packaging and transportation, but also convenient for disassembly and assembly.
