The utility model discloses a directional antenna array-based bushing partial discharge live detection apparatus. An electromagnetic wave signal radiated by local discharge is detected by virtue of the directional antenna array, and then is converted into a voltage signal so as to be output. A signal conditioner is used for receiving the voltage signal output by the directional antenna array, eliminating a received electromagnetic wave interference signal, amplifying the voltage signal and improving the signal-to-noise ratio. A high-speed signal collector is used for performing analog-to-digital conversion on the signal output by the signal conditioner and realizing the collection, storage and display of the digital signal. According to the apparatus disclosed by the utility model, a detection antenna is distributed in a safe region on the ground, so that the safety and reliability are high, and meanwhile, the sensor installation problem in the prior art is solved. The directional antenna array is adopted for
