Remote control automatic phase selecting switch

The utility model relates to a remote control automatic phase selecting switch belonging to the field of electric transformation and distribution equipment. In the utility model, the selecting switch is internally provided with three single-phase switches that are independent from each other and provided with an interlocking device mutually; power input ends of the single-phase switches are correspondingly connected with three phase lines of a three-phase circuit, and output ends of the single-phase switches are connected in parallel; a current transformer is arranged at the lower end where the output ends of the single-phase switches are connected in parallel; an electronic module is arranged on the selecting switch; the output end of the load current transformer is connected with a monitoring signal input end of the electronic module; a control signal output end of the electronic module is correspondingly connected with control ends of separating/closing control circuits or modules of the three single-phase switches in sequence; and a monitoring signal output end and a control signal input end of the electronic module are connected with a centralized control center by a wireless network or a carrier line. Besides the functions of leakage protection and current protection, the remote control automatic phase selecting switch can also remotely switch the phase sequence of a certain single-phase load line among the three-phase power supply of the power supply line, thus being beneficial to realization of balanced matching of interphase load.
