Abstract

PURPOSE:To prevent fire caused by a fine electric spark, by using two coils to feed a primary winding of one coil with a current as obtained by vectorial subtraction of current flowing through an impedance from a total current of a main circuit. CONSTITUTION:When current flows through a main circuit 4, a total current of a main circuit flows through a primary winding 11 of a coil 1, while current resulting from vectorial subtraction of current flowing through an impedance circuit 3 from a total current of the main circuit runs to a primary circuit 12 of the coil 1. This current flows in series through the primary winding 21 of the coil 2. A magnetomotive force of a core 1A gives a vector difference between a magnetomotive force attributed to the current of the primary winding 11 and that attributed the current of the primary winding 12. Then, a signal element of a spark current in a high frequency or a pulse overlapped with the current of the main circuit is obtained as voltage signal discriminated from a secondary winding of the coil 1 and a signal of a load current and a short- circuit current obtained as such done from a secondary winding 22 of the coil 2. A core forming the coils 1 and 2 should be made of an amorphous alloy composed mainly of cobalt.
