The invention discloses a data collecting and processing transmitting device of a noise cloud picture testing device in a transformer substation. The data collecting and processing transmitting devicecomprises a sensor plate, an FPGA (Field Programmable Gate Array), a power source and an upper computer. The power source is connected with the FPGA. The FPGA is connected with the upper computer. The FPGA comprises a data decoding module, a data processing module, an FIFO module and a communication module. The data decoding module is connected with the sensor plate through an external interface.Data received by the data decoding module is transmitted to the upper computer through the data processing module, the FIFO module and the communication module successively. The data collecting and processing transmitting device is lower in cost, low in functional redundancy, and higher in data transmission reliability.
