The invention provides an independent multichannel partial discharge analysis platform, and the platform comprises a signal processing display unit, a high-speed collection unit, signal conditioning units, and program control filtering units. The signal processing display unit is connected with the high-speed collection unit, the high-speed collection unit is connected with the signal conditioningunits, and the signal conditioning units are connected with the program control filtering units. The number of the signal conditioning units is not less than two, and the number of the program control filtering units is not less than two. The signal conditioning units are connected with the high-speed collection unit. The platform achieves the independent multichannel digital-type partial discharge measurement, and carries out the synchronous sampling, processing and display, wherein the synchronization error is less than 1ns. The platform is high in sampling rate, and employs multichannel simultaneous collection, wherein the maximum sampling rate of each channel is 80MS/s. The platform can achieve the effective discrimination of a discharge signal in a 0.3m range, and is widely used in partial discharge testing of high-voltage power equipment, including equipment delivery inspection, acceptance test, detection after overhaul, and pre-testing. The platform is provided with an expert analysis system. The platform can accurately analyze a partial discharge quantity of equipment, and can analyze the insulating conditions of the equipment.
