Motor, first is that fiberizer main motor, one is advance and retreat knife motor；Fiberizer main motor is variant according to the size of production capacity,
Main motor is possible to that 380V low voltage motor can be used, it is also possible to use 10KV high-voltage motor, this can be according to Factory Electricity Supply item
The difference of part is possible to different, and electrical control cabinet is not therefore also identical.And the general power of advance and retreat knife motor is all smaller (general
In 1.1kW or so), 380V motor is all used at home, and control also mainly uses Frequency Converter Control to meet advance and retreat knife to speed
The control requirement of degree.
The Normal practice of fiberizer electrical control cabinet is a set of control cabinet of main motor, a set of control of advance and retreat knife motor at present
Cabinet is being provided with two sets of field operation boxes respectively again at both fiberizer scenes；Therebetween the interlocking of existing hardwire also has logical
Cross DCS software interlock；Since control cabinet and control box are excessive, it be easy to cause each professional linking is indefinite, increases installation to connect
The workload of line and debugging, operational inconvenience；Because the control of advance and retreat knife, typically proposes demand by paper making arts,
Program is made according to process flow by Automation Specialty, and is finally that electric specialty is responsible for specific electrical control Interface design,
It is manufactured again by Pan Guichang according to the actual design reprocessing of electric specialty.
Up to the present there is no a kind of unified fiberizer field control casees, so that causing the field control case of design
Pattern is too many, and interface is inconsistent, be easy to cause each Specialty Design on linking, the confusion of the plant produced supply of material and execute-in-place
Inconvenience, so as to influence the duration of engineering and the efficiency of factory.

(SA1) 5, fast/slow selection switch (SA2) 6, main motor starting band button (SB1/HG1) 7, main motor stop band lamp and press
Button (SS1/HR1) 8, advance and retreat knife motor feed button (SBF) 9, advance and retreat knife motor withdrawing button (SBR) 10, the operation of advance and retreat knife refer to
Show lamp (HG1) 11, system failure indicator light (HY1) 12.
As shown in Fig. 2, being equipped with 380V incoming breaker (QF1) 13, direct current 24V breaker inside field control case
(QF2) 14,380V AC converter (INV) 15, terminal connections row 16.
Fig. 1, Fig. 2 said elements pass through control cabinet back panel wiring slot and are connected to connecting terminal block 16, with external wiring (packet
Include inlet-outlet line cable and each kind control cable) connected by connecting terminal block 16.
Fig. 3 show electric hookup and communication chart, and Fig. 4 show connecting terminal block figure；Above-mentioned two power supply as shown in the figure
Inlet wire connection jaws, 380V incoming breaker (QF1) 13,380V AC converter (INV) 15, connecting terminal block 16 are in control cabinet
It is sequentially connected in series；Inlet wire cable W1 is connected through connecting terminal block 16, and outlet cable W2 is through connecting terminal block 16 and advance and retreat knife motor sheet
Body connection.Power display 2 and the power supply of Main motor current display device 3 pass through cable W3 and DCS through connecting terminal block 16
System connection.The simulation control input of frequency converter (INV) 15 and power display 2 and Main motor current display device 3 are simulated
Amount input is connect by control cable W4 with DCS system through connecting terminal block 16.The input of frequency converter (INV) 15 and output end warp
Connecting terminal block 16 is connect by controlling cable W5 with DCS system.Band lamp scram button (SBE/HRE) 4, manual/auto selection
It switchs (SA1) 5, fast/slow selection switch (SA2) 6, main motor starting band button (SB1/HG1) 7, main motor and stops band
Button (SS1/HR1) 8, advance and retreat knife motor feed button (SBF) 9, advance and retreat knife motor withdrawing button (SBR) 10 are through terminals
Son row 16 is connect by controlling cable W6 with DCS system.The intrinsic blade position signal PX1 of fiberizer, PX2, PX3 pass through
Connecting terminal block 16 is connect by controlling cable W7 with DCS system.With the signal lamp in lamp scram button (SBE/HRE) 4
HRE, advance and retreat knife run indicator (HG1) 11, system failure indicator light (HY1) 12 pass through control cable through connecting terminal block 16

Signal lamp, main motor stop signal lamp with button (SS1/HR1) 8 through connecting terminal block 16 by controlling cable W9 and master
The control loop of motor controlling cabinet and the auxiliary contact of main contactor are separately connected.
Referring to Fig. 3, operation logic are as follows: when manual/auto selection switch (SA1) 5 is selected as automatic, pressed inside DCS
Programed interlocking executes instruction, and fast/slow selection switch (SA2) 6, main motor manually boot band button (SB1/HG1) 7, master
Motor stops band button (SS1/HR1) 8, advance and retreat knife motor feed button (SBF) 9, advance and retreat knife withdrawing button (SBR) 10 manually
It can be shielded by DCS, i.e., above-mentioned button input is invalid.DCS system passes through speed preset according to the set procedure and sends out into or move back
Knife instruction automatically adjusts refining concentration to frequency converter, frequency converter run signal RO1 and fault-signal RO2 can Real-time Feedback to DCS；
When there is emergency at scene, someone presses emergency stop band button (SBE/HRE) 4, DCS and preferentially executes stop command, jumps simultaneously
It opens main motor and advance and retreat knife motor and closes corresponding valve；To ensure safety, emergency stop Illuminated Switch (SBE/HRE) 4 it is normal
Closed contact also will disconnect the control loop of main motor simultaneously, it is ensured that main motor is when emergency stop band button (SBE/HRE) 4 is pressed one
Surely it can shut down.
When manual/auto selection switch (SA1) 5 is selected as manual, DCS program can be before and after fiberizer and defibrination process
The unlock of valve interlocked control, but fiberizer ontology signal detection is still effectively, and fast/slow selection at this time switchs
(SA2) 6, main motor manually boots band button (SB1/HG1) 7, main motor stops band button (SS1/HR1) 8, advance and retreat manually
Knife motor feed button (SBF) 9, the input of advance and retreat knife withdrawing button (SBR) 10 are effective；When DCS system detects that PX1 is in zero-bit
When, when the fast/slow selection switch selection of (SA2) 6 is quick, presses advance and retreat knife motor feed button (SBF) 9, DCS and pass through speed
And feed instruction is sent to frequency converter rapid feed, the quick, time at a slow speed is set in DCS by process flow；When into
Knife in place when, PX2 movement, DCS stops feed at this time, even if it is also invalid for pressing feed button (SBF) 9；Similarly, withdrawing
Only do inverse operation.
Above is a specific implementation of the utility model, therefore the description thereof is more specific and detailed, but can not be
And it is interpreted as the limitation to the scope of the utility model.It should be pointed out that for those of ordinary skill in the art, not
Under the premise of being detached from the utility model design, various modifications and improvements can be made, these obvious alternative forms are equal
Belong to the protection scope of the utility model.
