The invention discloses an interference signal simulation system for cable partial discharge field detection. The interference signal simulation system for the cable partial discharge field detection comprises a fluorescent lamp interference signal generation circuit and a simulation circuit used for simulating the cable partial discharge field detection, wherein fluorescent lamp interference signal generation circuit is placed on one side of the simulation circuit. The fluorescent lamp interference signal generation circuit comprises a first alternating current power supply, a switch, a frequency regulation device, a ballast, a fluorescent tube and an electric fluorescent starter, wherein two filaments are arranged in the fluorescent tube, the live line end of the first alternating current power supply sequentially passes through the switch, the frequency regulation device and the ballast and then is connected with one end of one filament, the null line end of the first alternating current power supply is connected with one end of the other filament, and the other ends of the two filaments are connected through the electric fluorescent starter. The system can simulate interference signals of the cable partial discharge field detection.
