Micropower infrared-communication current transformer

The invention discloses a micropower infrared-communication current transformer and relates to an electronic current transformer. The micropower infrared-communication current transformer is characterized by comprising the following structure: an embedded microcontroller (3) acquires data transmitted by a microcrystal iron core current transformer (1) through a data line; a power interface of theembedded microcontroller (3) acquires power from a bus induction power supply coil circuit (2); and the embedded microcontroller (3) interacts data with a current display terminal (6) which is provided with an infrared transceiver circuit through an infrared transmitting circuit (4) and an infrared receiving circuit (4). The micropower infrared-communication current transformer solves the problemthat the conventional high-voltage current transformer has high power consumption, large volume and high cost; the use safety is improved; the production cost is reduced; and the range of applicationis enlarged.
