Brief description
Fig. 1 is the circuit theory diagrams of the safe power supply control circuit of calibrating streamline each unit load of the present invention.
Specific embodiment
Specific embodiment one:With reference to Fig. 1, present embodiment is described, calibrating streamline includes multiple units, machine
People devan (taking table to pallet), pressure unit, camera unit, artificial plug-in card unit, four comprehensive calibratings line (every 20 epi-positions),
Artificial card taking unit, Intelligent seal unit, quarter code unit, labeling unit, robot group case (assets binding) unit etc., each is single
The load safe power supply independent control of unit, control principle is identical, and present embodiment provides the safe power supply control of a unit load
The physical circuit figure of circuit processed, and briefly explain its operation principle:
Unit load in normal range (NR), when electric current is not above setting electric current value, by transformer T1 by 220V alternating current
Pressure drop, to 12V alternating current, is filtered by rectifier bridge UR2, electrochemical capacitor C2, then becomes 12V DC voltage through 7805 voltage stabilizings, this 12V is straight
Stream voltage one side supplies VL1 luminescence display power consumption normal, is on the other hand supplied to KA and VL2, when power consumption is normal, in RP
The current potential that end is got is relatively low, and VT1, VT2 are not turned on, and KA coil must not be electric, and KA-2 does not close, then VL2 does not work, and now, KA-1 protects
Hold closure, then in this state, when pressing SB1, KM1 coil obtains electric, main circuit KM1-1 closure, connects main power source, for calibrating stream
Pipeline units normal power supply.
When unit load abnormal (electric elements excursion, short trouble etc.), the electric current in main circuit increases and is permitted
Many, the current surge that the current transformer TA primary side in measure loop flows through, also increase in TA secondary side induced-current, warp
After UR1 rectification, C1 filtering, the voltage got in potentiometer RP movable end increases, and VT1 base stage obtains trigger voltage, and VT1, VT2 lead
Logical, KA coil obtains electric adhesive, and KA-1 disconnects, and KM1 coil blackout discharges, and its main contacts KM1-1 disconnects and resetting, cut-out calibrating flowing water
Line unit main circuit power, simultaneously KA-2 closure self-locking, because button SB3 is break contact, thus relay KA persistently electric suction
Conjunction, the super power consumption of VL2 luminescence display or line fault.Only after reducing power consumption or be manually pressed by SB3, KA coil losing electricity is released
Put, KA-1 reset closure, KM1 again electric, KM1-1 close, connection main circuit power, power for this unit loads.
When KM1 obtains electric work, KM1-3 is to disconnect, and HL1 does not work, when a failure occurs the release of KM1 coil blackout,
KM1-3 recovers closure, then HL1 bright representing fault.
When power consumption is normal, KA must not be electric, and KA-3 remains open, and HL2 does not work, when power consumption exception or fault, KA
Electric adhesive, KA-3 closes, HL2 bright characterizing overload fault.
