The invention discloses a distributed high-frequency synchronous sampling data transmission method and device for a power distribution network and a medium. The method comprises the following steps: firstly, performing second alignment by a measurement terminal; then, the measurement terminal uploads sampling waveform data in a subpackage manner; dividing the sampling waveform data into a configuration packet and a waveform packet; the configuration packet is a transmitted first packet and is used for describing related illustrative information of the fault waveform; the waveform packet is used for storing waveform sampling data during a fault period; and the cloud end obtains the sampled waveform data uploaded in a subpackage manner, analyzes the sampled waveform data, and calculates to obtain the time mark and the name value of each data point in the sampled waveform data. Compared with a traditional method for hardware transformation on a terminal, the method has the advantage of low cost. Compared with tr
