Fig. 1 is circuit theory winding diagram of the present invention.
Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, the common port of the auxiliary switch F1 of automatic change-over backup circuit breaker is connected with power supply L on the wiring board, it is often opened node and is connected with the end of current-limiting resistance R, the other end of current-limiting resistance R links to each other with the anode of optocoupler U, the negative electrode of optocoupler U is connected with wiring board power supply N with emitter, the collector electrode of optocoupler U is connected with the end of control button S, the other end of control button S is connected with an end of the control coil of auxiliary relay K1, the other end of auxiliary relay K1 is connected with power supply L on the wiring board, and the common node of auxiliary relay K1 is connected with power supply L; The two ends of the control coil of auxiliary relay K2 are connected with the zero line NN of power supply A phase NA commonly used and power supply commonly used respectively; The two ends of the control coil of auxiliary relay K3 are connected with the zero line RN of stand-by power supply A phase RA and stand-by power supply respectively; The normally closed node of auxiliary relay K1 is connected with the normally closed node of auxiliary relay K3, after linking together, the common point of often opening node and auxiliary relay K3 of auxiliary relay K1 is connected to the end of often opening node of auxiliary relay K2, the other end of often opening node is connected with the common point of the auxiliary switch F2 of switch commonly used, the normally closed node of the auxiliary switch F2 of switch commonly used links to each other with an end of the positive switch coil of reversible electric machine M, and the other end of the positive switch coil of reversible electric machine M is connected with wiring board power supply N.
Explanation of nouns:
Haul oneself willingly into runback: automatic change-over is in the stand-by power supply power supply state, and power up commonly used just often automatically switches to power supply power supply state commonly used;
Haul oneself willingly into not runback: automatic change-over is in the stand-by power supply power supply state, power up commonly used just often, automatic change-over is failure to actuate; When stand-by power supply breaks down, automatically switch to power work state commonly used.
With reference to figure 1, when automatic change-over is operated in the stand-by power supply power supply state, the auxiliary switch F1 of backup circuit breaker often leaves the node closure, optocoupler U starts working, and when control button S pressed, relay K 1 control coil got, it often opens the node closure, waits for whether power supply commonly used recovers normal this moment.If recover just often, relay K 2 control coils get, it often opens the node closure, power supply L on the wiring board gives the forward coil power supply of reversible electric machine through the normally closed node of the auxiliary switch F2 of switch commonly used, the motor forward rotation makes uses switch closure always, its normally closed node is opened, and the forward coil losing electricity of reversible electric machine stops operating, and this process has been finished the function of hauling oneself willingly into runback.
When automatic change-over is operated in the stand-by power supply power supply state, when control button S lifts, relay K 1 control coil dead electricity, its normally closed node closure, relay K 3 control coils get, its normally closed node is opened, even this moment, power supply commonly used recovered normal, relay K 2 control coils get electric, and it often opens the node closure, the forward coil of reversible electric machine can not get electric rotation, and this process has been finished and hauled oneself willingly into the not function of runback; When having only the stand-by power supply dead electricity, relay K 3 control coil dead electricity, its normally closed node closure, this moment, power supply commonly used was normal, relay K 2 control coils get, it often opens the node closure, power supply L on the wiring board gives the forward coil power supply of reversible electric machine through the normally closed node of the auxiliary switch F2 of switch commonly used, the motor forward rotation makes uses switch closure always, its normally closed node is opened, the forward coil losing electricity of reversible electric machine stops operating, and this process has been finished and hauled oneself willingly into not under the runback state, and automatic change-over automatically switches to the not function of runback of hauling oneself willingly into of power supply power supply commonly used during the stand-by power supply fault.
