Ship-borne 110V power supply electric shock protection device

The utility model relates to a safety device for power utilization, particularly a ship-borne 110V power supply electric shock protection device which comprises a power supply transformer, a main circuit and a control circuit. The utility model is characterized in that the power supply transformer 380V/110V adopts a specially produced transformer of which the primary stage is in delta connection, the secondary stage is an independent three-phase winding output, and the phases are isolated from each other; simultaneously a center tap of each phase is served as a control signal source, a bridge rectifier stack is connected in the center top, and the other end of the center tap is connected to the ground. A highly sensitive current relay is connected in two DC output ends of the rectifier stack; a fuse RL1, an air switch Q and an AC contactor KM are simultaneously connected in the two output ends of each phase wire, and the three phases are completely symmetrical to form the main circuit. The control circuit is composed of buttons SB1 to SB3, an intermediate relay K1, an AC contactor KM, an indicating lamp XD8, etc.; the power supply adopts 380V, and three groups of control units are identical. The utility model is suitable for ship manufacture industry, has the characteristics of safety, reliability, high sensibility, etc., and can prevent electric shock accidents from occurring.
