Accompanying drawings structure of the present utility model and principle of work:
One, the principle of work of power supply conversion and control module is described in conjunction with Fig. 2 and Fig. 3.
The power supply of integrated control cabinet is by wherein a tunnel providing in the two-way power source bus, by switch SA1 branch " automatically " and " test I road ", " test II road ".
1. under the normal operating position, switch SA1 places " automatically " position
The accumulator that closes control miniature circuit breaker Q30, PLC, working sensor power supply DY work is given PLC respectively, is shown that touch-screen, sensor provide 24V, 24V, 12V power supply.At this moment, the output point 1402 of expansion I/O unit is ON, and auxiliary reclay KA5 coil gets electric, its normally opened contact closure, and PLC run indicator HL5 green light is bright.
1. the I road, when all there is electricity on the II road, miniature circuit breaker Q1, Q2 close, PLC is according to the balanced power supply principle, the odd number compartment selects the power supply of I road, even number compartment to select the power supply of II road, output point (1400,1401) is ON, auxiliary reclay KA6, KA7 coil get, its normally opened contact KA6, KA7 closure, it is electric to make that contactor KM1, KM2 coil get, KM1, the KM2 normally opened contact closure in major loop, and major loop has, because of I road, II road all have, KA1, KA2 coil get electric, its normally opened contact closure, and input signal is to the input point (0610,0611) of PLC; Switch SA1 (3,4) input signal is to the input point (0603) of PLC; Input signal is to the input point (0601,0602) of PLC after the normally opened contact closure of KM1, KM2; Display screen shows " I road, II road have ", " automatic power ", " I road or the power supply of II road " related words information; Make simultaneously power light HL1, HL2 green light bright after the normally opened contact closure of KM1, KM2.
If 2. the I road has electricity, II road not to have, then the KA1 coil get electric, the KA2 coil must not the electricity, PLC input point 0610 has signal, input point 0611 no signal, all compartment PLC make that by detection output point (1400) is ON, and it is electric that the KA6 coil gets, and the KM1 coil gets, automatically select the power supply of I road, by the load of the PLC control operation that reduces by half, feed back signal to the input point of PLC simultaneously, on display screen, show corresponding information.If this moment, the II road powered again, the KA2 coil gets electric, and input point 0611 has signal, and then even number compartment PLC makes that by detection output point (1401) is ON, and it is electric that the KA7 coil gets, and it is electric that the KM2 coil gets, and can reselect the power supply of II road.
If 3. the II road has electricity, I road not to have electricity, all compartment PLC can select the power supply of II road automatically by detecting, the load operation that reduces by half, and the while is pointed out corresponding information on display screen.If this moment, the I road powered again, then odd number compartment PLC can reselect the power supply of I road by detecting.
If 4. I road, II road all do not have, KA1, KA2 coil all must not, the input point of PLC (0610,0611) no signal, PLC enters dormant state automatically by detecting time-delay 3min, show that touch-screen does not have demonstration, hand can wake it up after touching and showing touch-screen, and about 3min that delays time does not have operation, will enter dormant state once more.If after I road or the power supply of II road, the input point of PLC (0610,0611) has signal, show that touch-screen will wake up automatically, and select power supply according to above-mentioned steps.
5. all there is electricity on I road, II road, and under the situation of I road, odd number compartment power supply, the power supply of II road, even number compartment, if I road (II road) power supply breaks down, KA1 (KA2) coil losing electricity, PLC are transformed into another road power supply power supply automatically, the operation that reduces by half of load simultaneously.After fault is got rid of, again Q1 (Q2) switch that closes power supply or by show that touch-screen presses " power failure source " soft-touch control earlier and stop power supply, press " opening power supply " soft-touch control again power again after, PLC changes back former current supply circuit automatically, after the PLC detection, the full carrying row of load restoration.When the duplex feeding loop powers again, PLC will be transformed into former current supply circuit automatically.
7. one the tunnel electricity is arranged, another Lu Wudian, all compartments all are under the situation of same road power supply, if this moment, current supply circuit broke down, KA1, KA2 coil all do not have electricity, then PLC stops power supply, and no longer carries out the conversion of current supply circuit.
8. also can be transformed into " automatically " position by " stopping " position by switch SA1 after fault is got rid of, PLC changes back former current supply circuit automatically, after detecting by PLC, and the full carrying row of load restoration.
2. when testing, switch SA1 can be placed " test I road " or " test II road ", artificially select power supply of I road or the power supply of II road, PLC only carries out detection alarm at this moment, can not carry out the conversion of electric power loop.
3. be connected to current sensor in the main circuit, voltage sensor and leakage alarm (30～300mA is adjustable), the voltage of surveying, current value is input to analog quantity input point (V1～V6 of PLC, V16), show the three-phase phase voltage that can show main circuit on the touch-screen, three-phase current, the power supply buses state, current supply circuit, information such as power supply status, when phase shortage appears in certain road power supply, overvoltage, under-voltage, faults such as three-phase imbalance, when leakage alarm detects electrical leakage above alarm setting value, show the prompting of screen displaying fault, PLC output point (1400,1401) be OFF, make KM1, the KM2 coil losing electricity, the disengagement failure electric power loop, PLC output point (1404 or 1405) is ON simultaneously, corresponding power supply trouble light HL1, the HL2 red light is bright.
4. during normal power supply, power supply is given air-conditioning unit, emergency power pack unit, lighting control unit power supply.
Two, illustrate that in conjunction with Fig. 2 and Fig. 4 air-conditioning unit control module controls the principle of work of one group of air-conditioning unit.
