It runs without interruption, rectification unit failure once repeatedly occurred, dry coke quenching is caused to stop production, influence the stability and safety of production.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of double rectification control systems of elevator,
Guarantee the powered operation of elevator motor in a manner of two sets of rectification switchings for acquiring spare mode, reduces the whole of elevator
It flows back to caused by road is broken down and shuts down.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of double rectification control systems of elevator, including
Motor module, rectification module branch, the control system further include spare rectification module branch, inlet wire switching cabinet, direct current switching
Cabinet, Alternating Current Power Supply are input to inlet wire switching cabinet, and the output end of inlet wire switching cabinet is separately connected rectification module branch and spare
Rectification module branch, the rectification module branch, spare rectification module branch are connect with the input terminal of direct current switching cabinet respectively, institute
The output end for stating direct current switching cabinet is connect with motor module.
The rectification module branch and/or spare rectification module branch include rectifier cabinet.
The control system further includes PLC controller, voltage and current acquisition unit, display, the voltage and current acquisition
Unit for acquiring the voltage and current signal of rectification module branch and spare rectification module branch respectively, with PLC controller
Input terminal connection, the output end of the PLC controller are connect with display, show voltage and current for controlling display.
Utility model has the advantages that due to acquiring emergency bypass so that wherein a branch trouble when, by another
Rectification branch work all the way, it is ensured that the work of elevator is reduced and shut down, dry caused by avoiding because of distillation unit failure to put out
Coke stops production；Condition also is provided for periodic maintenance maintenance by way of periodically switching, largely ensure that dry coke quenching mentions
The steady production of the machine of liter.
Detailed description of the invention
Below to each width attached drawing of description of the invention expression content and figure in label be briefly described:
Fig. 1 is the double rectification control system structural block diagrams of the present invention.
Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
As shown in Figure 1, a kind of double rectification control systems of elevator, including motor module, rectification module branch, spare rectification
Module branch, inlet wire switching cabinet, direct current switch cabinet, and Alternating Current Power Supply is input to inlet wire switching cabinet, and inlet wire switches the output end point of cabinet
Not Lian Jie rectification module branch and spare rectification module branch, rectification module branch, spare rectification module branch respectively with direct current
Switch the input terminal connection of cabinet, the output end of direct current switching cabinet is connect with motor module.Rectification module branch and spare rectification mould
Block branch is that direct current needed for converting alternating current to motor module by rectifier system is powered, and is switched by inlet wire
Cabinet and direct current switch the switching of cabinet to realize, rectification module branch and/or spare rectification module branch include rectifier cabinet.When wherein
When rectifier cabinet in one rectification branch breaks down, the rectifier cabinet for switching to another branch is powered, to guarantee to power
Stabilization and normal, reduce the machine halt trouble due to caused by the failures such as rectification I GBT breakdown in rectifier cabinet.
Voltage and current acquisition unit for acquiring the voltage and current of rectification module branch and spare rectification module branch respectively
Signal can acquire voltage, the current signal of two branches, voltage, current transformer respectively by voltage, current transformer
It is connect with the input terminal of PLC controller, for collected voltage, current data to be sent in PLC controller, PLC control
The output end of device is connect with display, shows voltage and current for controlling display.By acquiring two branch voltage signals, electricity
Stream information is known that the working condition of work branch first, according to voltage and current judge branch work it is whether normal, to monitoring,
Early warning provides parameter, by providing some basic datas to switch another branch work.Certainly further, it is possible to be sent out by PLC
Control signal can also be switched directly to control the switching action of inlet wire switching cabinet, direct current switching cabinet by the switching on switching cabinet out
Switching.
Switch cabinet by inlet wire and direct current switches the switching undisturbed of cabinet realization power module (rectification branch), when one group
Power module can be switched to another group of power module in time when something goes wrong and guarantee that dry coke quenching operates normally, while can be to failure
Power module carry out the inspection and replacement of electronic component, guarantee two can stand-by heat each other.The technology is mainly used in installation
Case frequency converter in the case of back-up system without using.To 3# dry coke quenching fault statistics over the years, the main factor of production is influenced just
It is elevator, and often most of failure appears in rectified feedback unit, therefore proposes to increase a set of spare commutating circuit, leads to
The mutual switching that inlet wire switching cabinet, direct current switching cabinet and change-over switch realize the old and new's rectified feedback unit is crossed, has it mutually
For the ability of stand-by heat.Since double commutation systems come into operation, working well, it is stable to cut, avoid because of rectified feedback unit therefore
Barrier causes dry coke quenching to stop production.And condition also is provided for periodic maintenance maintenance by way of periodically switching, largely
It ensure that the steady production of coke dry quenching hoister.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
