The invention provides an intelligent-type high-voltage metering device, and the metering device comprises a disconnecting knife switch, an electronic type combined transformer, a circuit breaker, and a three-phase electronic-type electric energy meter. In use, there is no need of an additional switch or circuit breaker. Moreover, the electronic type combined transformer can collect two line voltage signals and two phase current signals, enables the intelligent-type high-voltage metering device to be able to achieve the complete calibration through a three-phase voltage method, and improves the precision of the intelligent-type high-voltage metering device. Meanwhile, the electronic type combined transformer in the intelligent-type high-voltage metering device is connected with a metering module and a communication module through shielding stranded wires, and the electronic type combined transformer, the metering module and the communication module are poured into one body through insulating materials, thereby solving a problem that the prior art is liable to be affected.
