5The coil J that connects
1(closing coil 210), the electromagnetic force that hot-wire coil produces moves upward bracket component 218 thereupon, and the result who moves upward makes bracket component no longer push down movable contact spring 206 exactly.Movable contact spring moves upward under the effect of self bounce like this.Silver point 303 contacts on movable contact silver point 205 and the stationary contact 301,302 that is to say that at this moment power supply can be delivered to load end (Load) by stationary contact silver point 303 and being connected of movable contact silver point 205.
Fig. 6 A, Fig. 6 B are the design sketchs after GFCI connects, from the figure as can be seen, silver point 303 has been connected with silver point 205, bracket component 218 has separated with movable contact spring 206, iron core 204 ends and the permanent magnet 212 of bracket component 218 have separated, and the reaction force of spring 208 maintains this separated position.
GFCI divides the design sketch of having no progeny shown in Fig. 5 A and Fig. 5 B, at this moment iron core 204 ends and the permanent magnet 212 of bracket component 218 have combined, the other end is pushed down movable contact spring 206 downwards makes movable contact silver point 205 separate with stationary contact silver point 303, and keeps this disjunction situation up to pressing reset key 1012 once more with the suction-combining force of 204 of the iron cores in permanent magnet 212 and the bracket component.
The disjunction of GFCI is because circuit self exists leak current fault or neutral earthing fault or the artificial disjunction button of pressing.
(shown in Figure 7) detected magnet ring N when circuit existed leak current fault or neutral earthing fault
1This kind fault be can detect and 2 pin and 3 pin of IC (integrated package) testing result delivered to, amplify through IC, when in a single day this amplifying signal reached the threshold value of setting, 7 pin of IC were just exported a pulse signal, and the trigger end that this signal directly is sent to controllable silicon VD7 makes the VD7 conducting.A bigger electric current is just arranged by VD7 and the coil J that links to each other with VD7 after the conducting
2(broken coil 211).The electromagnetic force that broken coil 211 energisings produce moves downward bracket component 218.Push down movable contact spring 206 simultaneously and move downward together until movable contact silver point 205 and stationary contact silver point 303 are separated fully, and the permanent magnet of this moment holds firmly, and iron core 204 maintains this off-state in the bracket component.
When the people when pressing disjunction button 1011, the disjunction touch-switch 215 that is positioned at disjunction button 1011 belows also moves down thereupon, to the TEST switch closure that makes among Fig. 7.One end of this TEST switch is connected with the phase line of load end, and the other end passes through R
0Link to each other with the zero line of power end.Closed result just makes has an electric current to pass through on this loop, and this electric current is exactly an electric current of simulation leak current fault, and the result of this leakage current generating just makes the GFCI disjunction.What illustrate in the principle of disjunction and the epimere literal is consistent.Whether normally the disjunction of GFCI just just in time can illustrate that this device is in shape, reached detection GFCI purpose.
