Brief description of the drawings
Fig. 1 is circuit theory wiring diagram of the present invention.
Detailed description of the invention
For further understanding content of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to say in detailBright as follows:
As shown in Figure 1, the power supply on common port and the wiring board of the auxiliary switch F1 of automatic change-over backup circuit breakerL connects, and it is often opened node and is connected with one end of current-limiting resistance R, the anode phase of the other end of current-limiting resistance R and optocoupler UConnect, the negative electrode of optocoupler U is connected with wiring board power supply N with emitter stage, the colelctor electrode of optocoupler U and control button S'sOne end connects, and the other end of control button S is connected with one end of the control coil of auxiliary reclay K1, auxiliary reclayThe other end of K1 control coil is connected with the power supply L on wiring board, the common node of auxiliary reclay K1 and power supplyPower supply L connects; The two ends of the control coil of auxiliary reclay K2 respectively with zero of conventional power supply A phase NA and conventional power supplyLine NN connects; The two ends of the control coil of auxiliary reclay K3 respectively with zero of stand-by power supply A phase RA and stand-by power supplyLine RN connects; The normally closed node of auxiliary reclay K1 is connected with the normally closed node of auxiliary reclay K3, middle relayAfter linking together, the common point of often opening node and auxiliary reclay K3 of device K1 is connected to the Chang Kaijie of auxiliary reclay K2One end of point, the common point of often opening the other end of node and the auxiliary switch F2 of conventional switch is connected, and commonly uses the auxiliary of switchHelp the normally closed node of switch F2 to be connected with one end of the positive switch coil of reversible electric machine M, the positive switch coil of reversible electric machine MThe other end is connected with wiring board power supply N.
Explanation of nouns:
Haul oneself willingly into runback: automatic change-over, in stand-by power supply power supply state, when conventional power up is normal, automatically switches toConventional Power supply state;
Haul oneself willingly into not runback: automatic change-over, in stand-by power supply power supply state, when conventional power up is normal, is changed automaticallySwitch is failure to actuate; In the time that stand-by power supply breaks down, automatically switch to conventional power work state.
With reference to figure 1, when automatic change-over is operated in stand-by power supply power supply state, the auxiliary switch F1's of backup circuit breaker is normalOpen node closure, optocoupler U starts working, and in the time that control button S presses, relay K 1 control coil obtains electric, and it is often openedNode closure, now waits for whether conventional power supply recovers normal. If while recovering normal, relay K 2 control coils obtain electric,It often opens node closure, and the power supply L on wiring board gives reversible through the normally closed node of the auxiliary switch F2 of conventional switchThe forward coil power supply of motor, motor forward rotation makes conventional switch closure, and its normally closed node is opened, and reversible electric machine is justStop operating to coil losing electricity, this process has completed the function of hauling oneself willingly into runback.
When automatic change-over is operated in stand-by power supply power supply state, when control button S lifts, relay K 1 control coilDead electricity, its normally closed node closure, relay K 3 control coils obtain electric, and its normally closed node is opened, even if now commonly use power supplyRecover normal, relay K 2 control coils obtain electric, and it often opens node closure, and the forward coil of reversible electric machine can not obtain electric turningMoving, this process has completed hauls oneself willingly into the not function of runback; While only having stand-by power supply dead electricity, relay K 3 control coil dead electricity,Its normally closed node closure, now conventional power supply is normal, and relay K 2 control coils obtain electric, and it often opens node closure, circuitPower supply L on plate passes through the normally closed node of the auxiliary switch F2 that commonly uses switch to the forward coil power supply of reversible electric machine,Motor forward rotation makes conventional switch closure, and its normally closed node is opened, and the forward coil losing electricity of reversible electric machine stops operating,This process has completed to be hauled oneself willingly into not under runback state, and when stand-by power supply fault, automatic change-over automatically switches to conventional Power supplyHaul oneself willingly into the not function of runback.
