PROBLEM TO BE SOLVED: To obtain small-sized leakage-preventing equipment of high reliability. SOLUTION: In figure, the reference numeral 1 is constituted of the leakage- preventing equipment, the numeral 2 constituted of a main body, and the numeral 3 shown a commercial power source. The equipment 1 consists of an impedance 4, equivalent to a leakage impedance 8 of a load of the body 2, a switching part 5 for applying voltage to the impedance equivalent to the leakage impedance of the load, a drive part 6 for driving the switching part 5, and a control unit 7 for producing a switching pattern. The switching part 5 of the equipment 1 uses the output of a body converter 12 as a power source. A control unit 9 of the body 2 and the control unit 7 of the equipment 1 are realized on the same microprocessor, and its control is performed on a program assembled in the microprocessor. The drive part 6 and the switching part 5 are constituted of electronic components of low-current capacity (about at most 500 mA). |
