Fig. 3 is circuit diagram of the present utility model.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model comprises box body 1, master switch 3, be located at master switch 3 master pilot lamp 4 on one side and the jack 5 be located on box body 1, the below of described master switch 3 is provided with detection of electrical leakage switch 2, described master switch 3 is located on earth leakage protective device integrated box 9 with detection of electrical leakage switch 2, this integrated box 9 is positioned on cover plate 8, described cover plate 8 coordinates with draw-in groove 7, be provided with monophase leakage protector in described integrated box 9 and be connected to the fuse at monophase leakage protector rear, described monophase leakage protector comprises instrument transformer and release, the phase line L exported by master switch 3 and neutral line N bis-wires are simultaneously through unshakable in one's determination, jack 5 is connected to through fuse, instrument transformer is wound on iron core, release is connected with master switch 3, electric-leakage detection circuit is connected with between the phase line L at the two ends of described iron core and neutral line N, this electric-leakage detection circuit is in series with detection of electrical leakage switch 2, Detection capacitance C and detection resistance R, described integrated box 9 is fixedly connected on cover plate 8, this cover plate 8 is fixedly connected on draw-in groove 7 by screw through screwed hole 81, the position that the front of described box body 1 is relative with integrated box 9 is provided with switch groove 11, described jack 5 is divided into two jacks and three jacks, the side of each jack 5 is provided with corresponding indicator light 6.
During use, electrical equipment is connected in the jack 5 on box body 1, and when master switch 3 closes, the electric current flowing through phase line L and neutral line N is respectively I
1and I
2if leakage current is Id, Id=I1+I2=0, now through main circuit current I1 and I2 equal and opposite in direction on ring-shaped core, direction is contrary, the total magnetic flux φ 1+ φ 2=0 produced in iron core, therefore another secondary winding loop on instrument transformer ring-shaped core does not have induced voltage U=0, release is failure to actuate.When there is electric leakage, produce leakage current Id, Id=I1+I2 ≠ 0, the resultant flux φ 1+ φ 2 ≠ 0 produced in iron core, then upper secondary winding loop unshakable in one's determination produces induced voltage U ≠ 0, and when leakage current increases to predetermined numerical value, induced voltage U also increases to predetermined numerical value, release action, master switch 3 disconnects.Before use, closed detection of electrical leakage switch 2, utilizes the stability of the monophase leakage protector in electric-leakage detection circuit determination integrated box 9.And; integrated box 9 is arranged on cover plate 8; cover plate 8 is fixedly connected on draw-in groove 7 by screw through screwed hole 81, and when earth leakage protective device breaks down needs replacing time, only need pull down cover plate 8 changes integrated box 9 casing; it is convenient to change; save time, monophase leakage protector and fuse, composition dual fail-safe; break off the generation of dangerous accident, guarantee personal safety.Further, the side of each jack 5 is provided with corresponding indicator light 6, shows the energising situation of each jack 5 intuitively.
It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
