1Another end line X
2Link to each other.
The operation principle of present embodiment is: as the primary winding L of transformer B
1End line X
1, X
2When connecting the 380V alternating current, the 380V alternating current is through crystal diode D
5Halfwave rectifier becomes the 170V direct current, and this voltage is to capacitor C charging, and the bigger charging current of generation, because capacitor C is connected across between the collector electrode and base stage of triode T, this charging current is base current, and triode T is moved full closing under the state, and this moment, the 170V direct current removed diode D
5Pressure drop 0.7V outside the triode pressure drop 0.3V, all is added on the ac contactor coil IC, A.C. contactor adhesive (i.e. starting).Meanwhile, the bridge rectifier output low-voltage DC (8V) in the operation power supply also is added in the two ends of coil 1C, but owing to is lower than the 170V direct voltage of startup power supply. diode D
1～D
4Being in cut-off state. capacitor C charging finishes gradually after the several seconds, be that charging current is 0 gradually, and the resistance R value is very big, so the base current of triode T diminishes gradually, triode T is transformed into cut-off state by saturation condition gradually, and the pressure drop at triode T two ends becomes greatly gradually, and the voltage at coil 1C two ends diminishes gradually, when when equaling to move the voltage of power supply output low-voltage DC, diode D
1～D
4Conducting, the operation power supply works, and provides for coil 1C and keeps electric current, makes A.C. contactor continue to keep adhesive.Primary winding L as transformer B
1End line X
1, X
2. during with the disjunction of 380V alternating current, the low-voltage DC of operation power supply is outage thereupon also, after the ac contactor coil 1C outage, the A.C. contactor disjunction, meanwhile the capacitor C in the startup power supply discharges by resistance R, and discharge finishes after the several seconds, gets ready for start A.C. contactor next time.
The design feature of the utility model second embodiment is (referring to an accompanying drawing 2): the operation power supply is identical with last embodiment, and startup power supply comprises the winding L of paying of transformer B
3, crystal diode D
5, D
6, triode T, resistance R, capacitor C, auxiliary relay J; Capacitor C be connected across between the collector electrode and base stage of triode T after resistance R is in parallel.The collector electrode of triode T is by diode D
6With a pair winding L
3Upper end links to each other, and the emitter of triode T links to each other with the coil end 6 of auxiliary relay J, another termination 5 and pair winding L of auxiliary relay J coil
3Lower end link to each other; Diode D
5An end and L
1End line X
1Link to each other, the other end links to each other another termination and the L of 1C coil by the normally opened contact JK of auxiliary relay J with the termination 8 of ac contactor coil 1C
1Another end line X
2Link to each other.
The operation principle of present embodiment is: as end line X
1, X
2After connecting the 380V alternating current, pay winding L
3The alternating voltage of output is through crystal diode D
6After the halfwave rectifier, to the capacitor C charging, this charging current is the base current of triode T, and this electric current is very big; Triode T is worked under saturation condition, auxiliary relay J adhesive, its normally opened contact JK is also closed thereupon.The 380V alternating current is through D like this
5Halfwave rectifier is the 170V direct current, just can be added on the ac contactor coil 1C through the normally opened contact JK of closure.Therefore A.C. contactor adhesive (i.e. starting).Meanwhile, operation power supply output low-voltage DC is held the two ends that also are added in coil 1C through "+" end and "-" of bridge rectifier, owing to be lower than 170V, so D
1～D
4Four transistors end.After several seconds, the capacitor C charging finishes gradually, charging current is reduced to 0 gradually, and the resistance R value is very big, so the base current of triode T reduces gradually, triode T is gradually by the saturated cut-off state that becomes, auxiliary relay J discharges thereupon, its normally opened contact JK reset disconnection, disconnect the 170V direct voltage of Dx output, meanwhile, diode D
1～D
4Conducting, the operation power supply provides to coil 1C keeps electric current, makes A.C. contactor continue to keep adhesive.As end line X
