Description
Technical field
The present invention relates to raising cabinet internal fan control circuit and control method for fan.
Background technique
Currently, it is electric (ZC) main control is not conformed to, (drivers' cab is walked as long as the rotary switch of right joint action table is got to walking gear
And ground running), raising cabinet internal fan is just run, while also being needed on driver after operating ground running to general in drivers' cab
Rotary switch gets to drivers' cab and plays upshift, otherwise will lead to raising cabinet internal fan longtime running, greatly reduces fan service life,
Electricity consumption is caused to waste simultaneously.
Summary of the invention
The technical problem to be solved by the present invention is in view of the shortcomings of the prior art, provide a kind of raising cabinet internal fan control
Circuit and control method for fan extend fan service life, reduce the waste of electricity consumption.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of raising cabinet internal fan control circuit,
Including first contactor；The coil both ends of the first contactor are connect with main control power supply；The first of the first contactor
Normally opened contact is connected with the normally opened contact of walking contactor in cabinet is supported, forms the first series arm, first series arm
It is in parallel with blower contactor normally opened contact is supported；Walking contactor in the second normally opened contact and opening and closing cabinet of the first contactor
Normally opened contact series connection, forms the second series arm, and second series arm is in parallel with opening and closing blower contactor normally opened contact；Institute
It states the first series arm, blower contactor normally opened contact one end is supported to connect electrical cabinet fan power anode by the first fan, separately
One end connects electrical cabinet fan power negative terminal；Second series arm, opening and closing blower contactor normally opened contact one end pass through the
Two fans connect electrical cabinet fan power anode, and the other end connects electrical cabinet fan power negative terminal.
Coil one end of the first contactor connects the main control power supply by the normally opened contact of spare relaying.
Correspondingly, the present invention also provides it is a kind of using above-mentioned raising cabinet internal fan control circuit control fan method,
This method mainly realizes process are as follows: after getting to walking/opening and closing or walking/support gear and closing main control electricity, is opened and closed cabinet
Interior walking contactor, support blower contactor coil obtain electric, walking contactor, support blower contactor normally opened contact in opening and closing cabinet
Closure；Reserve trunk circle obtains electric, spare relaying normally opened contact closure, the coil of first contactor obtain it is electric, first contactor
First normally opened contact, the second normally opened contact closure, so that fan is run.
Compared with prior art, the advantageous effect of present invention is that: utilize circuit and method of the invention, only exist
Fan is just run when closing main control electric (ZC) and operation walking motion, can be accomplished the reasonable operation of fan in this way, be reduced simultaneously
The time used in door machine, extends fan service life, reduces the waste of electricity consumption above and below driver.
Detailed description of the invention
Fig. 1 is first part of embodiment of the present invention circuit diagram；
Fig. 2 is second part of embodiment of the present invention circuit diagram；
Fig. 3 is present procedure control principle drawing one；
Fig. 4 is present procedure control principle drawing two.
Specific embodiment
Fig. 1 is the member control circuit of fan operation, and Fig. 2 is the control circuit of H3KM3 normally opened contact in 1.
H3KM3 be incremental contact device and its normally opened auxiliary contact, C9K6a be it is spare relaying and its normally opened auxiliary contact,
P6E31, P6E32 are electrical cabinet fan power, and P4E21, P4E22 are main control power supply, and H3KMF is that opening and closing blower contactor is normally opened
Contact, H3KM2 are contactor normally opened contact of walking in opening and closing cabinet, and H6KM is to support that blower contactor normally opened contact H6KM2 is branch
Hold contactor normally opened contact of walking in cabinet.
After getting to walking/opening and closing (walking/support) gear and closing ZC, contactor of walking in opening and closing/support cabinet
(H3KM2/H6KM2) coil obtains electric, normally opened contact H3KM2/H6KM2 closure.After Fig. 1 access, C6K6a repeating coil is obtained
Electricity makes Fig. 2 access, and H3KM3 contactor coil obtains electric in Fig. 2, and H3KM3 normally opened contact is closed in Fig. 1, to be able to achieve Fig. 1
The operation of middle fan；After Fig. 1 open circuit, C6K6a repeating coil power loss keeps Fig. 2 breaking, and H3KM3 contactor coil loses in Fig. 2
Electricity, H3KM3 normally opened contact disconnects in Fig. 1, so that it is out of service to be able to achieve fan in Fig. 1.
In Fig. 3, C9K6a is spare part relaying, and the C9K6a coil in corresponding program, this program segment is able to achieve walking motion control
The operation of raising cabinet internal fan processed
Left lateral (M03800/MB000414)/right lateral (M03801/ when handle gets to left lateral/right lateral movement, in program
MB000415) opened point is logical, this program segment access, C9K6a coil obtains electric；Left lateral (M03800/ when handle zero-bit, in program
MB000414)/right lateral (M03801/MB000415) normally opened point off, the open circuit of this program segment, C9K6a coil losing electricity.
Using circuit of the invention, the time required to eliminating door machine operation up and down, it can directly complete to control, walk under machine
It is about 10 seconds time-consuming；Single saves the time 279.3 seconds.One door machine is only walked when rotary switch is got to walking gear
Fan is just run when movement, and walking motion terminates rear fan delay and is automatically stopped operation in 3 minutes.One door machine, transformation before with change
Fan after making is lost at least in 5/year.
There are 10 door machines to need not operation later of walking under machine daily assuming that general purpose port is average, same day door machine driver needs complete
Other door machine operations in portion, therefore above situation will occur.
Therefore single device saves the time are as follows: 558.6 seconds；
This time transformation income can be calculated according to production operation efficiency.
If the annual working days of general purpose port door machine are 200 days；
It can be calculated according to control room offer equipment average operation efficiency as follows:
Operation steel are averaged single line efficiency are as follows: 164.125 ton/hours；
Therefore show that this transform the general code first year (theory) extra earning as:
164.125 ton/hours * 0.155 hour * 10 * 23 yuan/ton * 200 days+60 yuan * 5/years * 10+1 ten thousand yuan * 10
Platform=1273211.3 yuan.
