Integrated high-voltage broadband digital carrier machine

The invention relates to the technical field of high-voltage power carrier communication, and particularly relates to an integrated high-voltage broadband digital carrier machine. The integrated high-voltage broadband digital carrier machine includes a high-voltage power line connecting terminal connected with a high-voltage power line; a high-voltage ceramic capacitor; a coupling transformer, and a digital carrier device. The connecting terminal is successively connected with the high-voltage ceramic capacitor, the coupling transformer and the digital carrier device. The broadband digital carrier device is integrated with a high-voltage coupler and is communicated with other devices with digital signals, so that the problems of signal attenuation and interference between the coupler and the carrier device in the high-voltage carrier communication due to the over-long cable are solved, and the reliability of the carrier communication is improved; and the high-voltage ceramic capacitor developed for the high-v
