3 3 PHASE ALL-IN-ONE TYPE CURRENT TRANSFORMER FOR WATT-HOUR METER

摘要

The present invention relates to a current transformer for a three-phase integrated power supply and a power meter.According to one embodiment of the present invention, a current transformer for a three-phase integrated power supply and a three-phase current transformer is connected to three phases (A, B, and C) of an integrated watt hour meter, and three current transformers for measuring currents of A,; A loading unit on which the three current transformers are mounted; A terminal block mounted on the mounting table and connected to the primary and secondary terminals of each of the A, B, C phases of the integrated watt-hour meter through a voltage measuring terminal through a wire; And a terminal protection cover which is mounted on the three terminal units and the terminal block and protects the upper terminal.;
