    • A leakage protection method and device having a live/neutral wire identification function that identify the live wire and neutral wire of an input power source by means of a live/neutral wire identification device 1. If the live/neutral wires are discovered to be erroneously connected, the connections between the live wire L' and the neutral wire N' of an electric device and the live wire L and the neutral wire N of the power source are immediately adjusted directly or indirectly; or, the connection of a surface leakage signal pickup device 2 is adjusted; or, a main circuit switch K is made such that the main circuit switch cannot close the circuit or that the main circuit switch breaks the circuit immediately after closing the circuit, so that a user must correct the connections of the live/neutral wires of the power source; the surface leakage signal pickup device 2 is arranged such that said device is always connected to the neutral wire N of the power source and to the surface F of the electric device, so as to always monitor the electric potential of the surface F of the electric device over the neutral wire N of the power source. When the electric device surface leaks electricity, the leakage signal pickup device 2 immediately drives an electromagnetic tripping device 3 to break the main circuit switch 3, thereby breaking the connection between the electric device and the power source. The method and device of the present invention can remove leakage before a human body experiences an electric shock, thereby eliminating potential accidents; leakage accidents due to connection errors are prevented; electric device surface leakage can be effectively prevented even when the electric device is not connected to ground.

    • A method of electricity leakage detection and prevention of electrical equipment's outer surface and system thereof. The method and system are used for detecting and preventing electricity leakage of the electrical equipment's outer surface caused by defective insulation and power supply connection faults. By monitoring the current path (2) formed between the electrical equipment neutral line (Nu') and the electrical equipment's outer surface (G') and monitoring the current value thereof, an electricity leakage of the outer surface of electrical equipment can be detected without human intervention, and the connection between the electrical equipment and the power supply can subsequently be cut off and an alarm activated. In the system, a power supply path (5) is set up to ensure a source of power, and thereby normal operation, even when the power supply connection fails. According to the method and system, the electricity leakage of the outer surface can be correctly detected and the alarm can be activated or the connection between the electrical equipment and the power supply can be cut even if the electrical equipment's outer surface is free. With the advantage of simple construction and low cost, the system can be widely used.
