Secondary nuclear phase device of combined transformer

The invention provides a secondary nuclear phase device of a combined mutual inductor. The device comprises a shell, and a control processor and a power supply module are arranged in the shell; a display screen is arranged on the front side of the shell; two sides of the housing are respectively provided with alligator clips connected with the electric energy meter and wiring pins connected with an aviation plug of the combined mutual inductor. The power supply module, the display screen, the alligator clips and the wiring pins are connected with the control processor, wherein the control processor performs data processing by using a BASIC language algorithm, the display screen is an OLED display screen, the alligator clips comprise a plurality of alligator clips with different colors andprovided with labels, and the wiring pins comprise wiring pins with labels. The secondary nuclear phase device of the combined mutual inductor is simple in nuclear phase process, safe and efficient. 本发明提供了一种组合式互感器二次核相装置，包括壳体，
