Said power failure button assembly comprises manual power failure button 43 and connected power failure button guide rod 44; The upper end of said power failure button guide rod 44 is provided with turn-off reset spring 45, and said power failure button guide rod 44 passes the said switching-over locking slide plate 25 that is mated use.
Workflow of the present invention is: the present invention is divided into manual control and pulse control two parts, realizes the mechanical latching function through A, B, C switching-over assembly, when manually controlling; If 3,4 normal conductings battle of switch ATN have explained that one is closed mutually, must press manual power failure button; Make switch ATN reset, just can carry out the commutation operation, otherwise; Because the mechanical latching function of A, B, C switching-over assembly 14 makes switch ATA, ATB, ATC to press, after being resetted, switch ATN just can carry out switch ATA, ATB, the arbitrary push-botton operation of ATC; But the mechanical latching function of A, B, C switching-over assembly can't make two or three in ATA, ATB, the ATC switch to press simultaneously, as switch ATA, ATB, when the arbitrary button of ATC is pressed; 14 of moving contact assembly, A, B, the C switching-over group of the button of pressing through correspondence drive zero line and drag slide plate and move downward; Corresponding electromagnet energising adhesive drags corresponding contact KA, KB or KC (moving contact 28) closure, and in this process, the normally closed point 1,2 of switch ATN keeps conducting state always; When switch ATA, ATB, the arbitrary button of ATC drop to a certain degree; The stroke that this preferred embodiment moves downward is greater than when the 4mm, and the insulation stroke guide rod that zero line drags on the slide plate makes the normally closed point 1,2 of switch ATN break off, and often makes war 3,4 to connect; At this moment, press the button corresponding electromagnet coil outage and accomplish switching-over.If normal 3, the 4 not conductings of making war of switch ATN are so directly pressed ATA, ATB, the arbitrary button of ATC and pressed up to by till motionless, just accomplished switch operation.During pulse control; The external command pulse duration satisfies one of electromagnet coil N and electromagnet coil A, B, C sum pickup time; Said and gate control circuit is realized the logic control of external control signal to photoelectrical coupler; Photoelectrical coupler A ', B ', the conducting of C ' ability come DM loop A, B, C adhesive when having only NAND5, NAND6, NAND7 output electronegative potential HF3, HF4, HF5 output high potential, and the conducting of photoelectrical coupler N ' ability comes DM coil N adhesive during 4 high potentials.This circuit is when 4 electronegative potentials; A, B, C point have only any be high potential corresponding light electric coupling just conducting drive the respective electrical magnet coil adhesive locking slide plate mechanical latching that resets, make 1,2 two of the normally closed points of switch ATN break off the power down of corresponding light electric coupling, electromagnet coil is no longer worked; Thereby avoided DC electromagnet pickup time long and cause the overheated generation of burning phenomenon of DC electromagnet; 3,4 two conductings are even 4 of this moments be high potential, because D6 output high potential is until this operating impulse end; The electromagnet coil N of HF2 output electronegative potential can't adhesive, and not conductings of photoelectrical coupler N ' in other cases.During 4 high potentials; Corresponding light electric coupling A ', B ', the not conductings of C ' in any case of A, B, C point; HF1 exports electronegative potential, and D6 exports electronegative potential, and HF2 output high potential photoelectrical coupler N ' conducting DM coil N adhesive has a power failure; 3,4 two disconnections, corresponding state when carrying out 4 electronegative potentials.R5 is a pull down resistor, and C2 trembles electric capacity and prevents to cause malfunction because of switch from fluttering for disappearing.D10, D11, D12, D13 are voltage stabilizing didoe, and C3, C4, C5 are energy storage capacitor, just can reach the locking stroke during switching-over slide plate slip 5mm, and the inertia that leans on C3, C4, the discharge of C5 energy storage capacitor this moment and move iron core is accomplished the locking stroke.
Certainly; Above-mentioned explanation is not the restriction to the utility model; The utility model also be not limited only to above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also belong to the protection range of the utility model.
