Top rapping control system used for electric precipitation

The utility model relates to a top rapping control system used for electric precipitation. The top rapping control system is used for solving the problems of the existing top rapping control system that the number of control points is large, the overcurrent and open circuit detection is imperfect, the turn-off of a rapping hammer is not in time, the rapping hammer is mal-operated easily and residual voltage exists after the rapping hammer is turned off. The control system comprises a power supply main circuit, a rapping hammer control system and a PLC (programmable logic controller) control system, wherein the power supply main circuit comprises an inlet wire switch, a fuse protector, a transformer, an alternating current solid-state relay, an open circuit detecting resistor, a rectifier bridge, a current detecting plate and the like. The rapping hammer control system comprises a direct current solid-state relay, a protection diode, a reverse fly-wheel diode, a rapping hammer and the like, and the PLC control
