The course of work of electric cabinet is as follows：
1st, the circuit breaker Q F2 inside control cabinet is closed, dc source U1, U2 connect alternating voltage AC220V.
2nd, the toggle switch QF2 on guidance panel, can select power supply U1 or U2, and U2 is stand-by power supply if U1 is selected,
U1 is stand-by power supply, i.e. U1 and U2 stand-by power supply each other if U2 is selected.Now DC control circuit power on.
3rd, because stop button SB4 is normally closed, DC voltage is+24V by SB4, i.e. Line 1, then power supply indicator
Light, while the powered+24V of rotary switch QC1 inputs on panel.
If the 4, rotary switch QC1 selects " continuous " shelves, No. 25 lines and No. 26 lines are simultaneously+24V.No. 25 it is powered then
Continuous mode HL-9 indicator lamps are lighted.No. 26 it is powered after pass through the normally-closed contact KT1 of master timer and each electrothermal relay and aid in
After normally-closed contact, No. 10 line is+24V, after No. 10 line is by frequency converter internal protection normally-closed contact " RA-RB ", No. 11 lines for+
24V。
5th, after No. 11 tape electricity, enter paddy button SB1 on following if pressed, enter paddy relay KC7 adhesives, due to KC7
Contact self-locking action, enters paddy relay KC7 and keeps attracting state.Enter paddy indicator lamp HL-2 simultaneously to light, level detector motor relay
Device KC-1 is acted, and level detector is started working.Because the interlocked of KC7 normally-closed contacts is used（Now disconnect）, wire size 37 and 43 without
No matter electricity, now press dry button SB2 or discharge button SB3, dries or the discharge equal akinesia of relay, i.e., can not carry out
Dry or discharge work.After KC7 normally opened contact adhesives, wire size 57 is+24V, exhaust blower motor DC contactor KM1 coil band
Electricity work, exhaust blower is started working.KM1 contactors are acted, and it aids in normally opened contact KM1 actions, because R2 is AC220V, then line
Numbers 56 be AC220V, then A.C. contactor KM5 coil workings, the work of dust discharge motor, while time relay KT3 work meters
When.After KT3 timing is reached, its normally opened auxiliary contact KT3 adhesive, then wire size 58 is AC220V, then A.C. contactor KM6 lines
Enclose work, equal separated motor work, the timing while time relay KT4 works.After KT4 timing is reached, its normally opened auxiliary contact KT4
Adhesive, then wire size 45 is AC220V, then A.C. contactor KM3 coil workings, elevator work, while the time relay
KT5 work timing.After KT5 timing is reached, its normally opened auxiliary contact KT5 adhesive, then wire size 46 is AC220V, and then exchange connects
Tentaculum KM2 coil workings, base electrical machinery work, auxiliary contact KM2 adhesives, wire size 71 is AC220V, and frequency converter contactor KM4 is moved
Make, frequency converter access power supply.The timing of time relay KT6 work simultaneously.After KT6 timing is reached, its normally opened auxiliary contact KT6 inhales
Close, in being to turn on revolving valve prograde circuit, direct current auxiliary reclay KC11 actions are rotated forward after its auxiliary contact adhesive to frequency converter
Signal, then frequency converter work, i.e. blow-off valve variable frequency work.
6th, after No. 11 tape electricity, paddy button SB1 is entered on following if pressed, if pressing dry button SB2 or the row of pressing
Go out button SB3, the step of action of its drying process or discharge process act similar above-mentioned 5.
Its operation principle is as follows：
Relay, contactor its coil rating operating voltage is AC220V, the rated operational voltage of its pick-up voltage≤80%, and it is inhaled
It is some numerical value less than or equal to 220x0.8=176V to close voltage, that is, when starting control circuit, only work as control line
When the operating voltage on road is more than AC176V (or certain value less than 176), relay, contactor in circuit could adhesives.China
Relevant laws and regulations are provided：To low-voltage electricity user, the tolerance of user's receiving end supply voltage is -7%~+7%.It is i.e. normal
Line voltage distribution voltage change is minimum to be not less than AC204.6V.Because of 204.6V ＞ 176V, therefore the power supply of normal power supply capacity greatly, will not
When starting, relay, contactor are unable to adhesive to cause equipment to be unable to normal starting.
But, when running into power supply capacity deficiency, restart the larger motor of power, because motor starting currents are normal
5-7 times of operating current, it is many that excessive transient starting high current causes system voltage drop to decline, and can be less than the adhesive of relay
Voltage AC176V, so as to cause relay to keep adhesive.
Switching Power Supply electricity consumption input is typically entered can normal work, limit range AC85- in the range of AC100-240V
265V, for general voltage instability, excessively low phenomenon, output voltage is stable direct current, selection output DC24V 5A, as long as electric
It is pressed in the range of AC85-265V and fluctuates, output DC24V is stable.That is, caused by big motor starting up moment, even if off-capacity
The very low AC85V that declines of power circuit, Switching Power Supply can also export stable direct current 24V power supplys, guarantee of power device
The direct current 24V of control relay, contactor normal work.
Switching Power Supply uses two-way, standby each other, even if a failure, another it is standby it is i.e. changeable use,
It ensure that the reliability of system.
In system after heavy-duty motor normal work, the normal value that moment low supply voltage rises, it is low power its
The contactor of its each circuit for controlling motor presses technological requirement order adhesive, so that whole control system all normally starts.
Citing described above for best mode for carrying out the invention, wherein the part do not addressed in detail is that this area is common
The common knowledge of technical staff.Protection scope of the present invention is defined by the content of claim, any technology based on the present invention
