The invention provides a portable checking and discharging electric rod for a subway overhead line system. The portable checking and discharging electric rod comprises a checking and discharging electric connecting rod mechanism, an operating rod and a grounding mechanism. One end of the checking and discharging electric connecting rod mechanism is connected with the front end of the operating rod, a connecting mechanism detachably connected with the grounding mechanism is arranged between the checking and discharging electric connecting rod mechanism and the operating rod, and the operating rod is connected with the checking and discharging electric connecting rod mechanism through the connecting mechanism; the checking discharge electric connecting rod mechanism comprises a conductive hanging rod, an insulating rod and a measuring terminal; the conductive hitching rod is connected to the upper end of the insulating rod and is used for hitching a subway overhead line system after power failure; the lower end of the insulating rod is connected with a connecting mechanism and is detachably connected with an operating rod through the connecting mechanism, the operating rod and the insulating rod are coaxially arranged, the measuring terminal is electrically connected with the conductive hanging rod through a connecting wire in the insulating rod, the measuring terminal can be used for detecting the residual voltage of the overhead line system after power failure, and the measuring terminal is further electrically connected with a grounding mechanism. On-site rapid assembly and disassembly are facilitated, the preparation time before operation is shortened, and the operation efficiency is improved.
