Description
Technical field
The present invention relates to a kind of methods that frequency inverter capacity maximally utilizes, and in particular to a kind of tippler resets the change of machine
The method that frequency device maximum capacity utilizes.
Background technology
Frequency converter is because having the advantages that adjusting frequency and slow turn-on is widely applied.Work(when frequency converter dispatches from the factory
Generally there are certain surpluses for rate setting, under the premise that security is guaranteed, give full play to the surplus of frequency converter and pass through adjusting
Actuation time of frequency converter etc. can reach the capacity extension of frequency converter, in this way, the effect of frequency converter can either be given full play to again
The expense for buying frequency converter again can be saved.My company's tippler, which is resetted, designs 4 motor drivings, contributes as 48 section train weights
Railway carriage, train come vehicle be more than 48 section when, current of electric off-rating, occur " high load with small power " phenomenon, long-play meeting
It causes transmission gear to damage, influences the service life of transmission gear, therefore need a spare motor to improve and reset output, spare motor
The capacity of frequency converter cannot be met the requirements afterwards, very high expense be needed if replacing frequency converter, for this situation, by changing
The mode for becoming frequency converter setting promotes the ability of frequency converter.Now use motor rated power for 63KW, rated current 125.8A,
Four operation when general power be 252KW, rated current 503.2A, frequency converter rated power be 315KW, rated current 590A,
Switch 1050A, contactor 800A, thermocouple 130A are selected, after a spare motor, five motor general powers are 315KW, specified electricity
629A is flowed, is more than the capacity of current frequency converter, trip phenomenon occurs in operation.

Switch is attracted, and relay 1ZJ is made to be powered, and spare motor preparation picks up, and is arrived after picking up when tippler readjustment machine runs to vehicle
When level is for decoupling device, signal, the normal open switch of contactor KM disconnect hair vehicle in place, and spare motor is out of service, follow-up spare
Motor dallies with speed reducer, resets and drives operation by remaining motor as usual, standby in order to avoid falling large arm error starting when unloaded test run
With motor, in logic large arm being lifted instruction, signal is in parallel in place with vehicle, improves reliability.When dumping to regulation joint number or
When carrying out vehicle less than regulation joint number, PLC controls spare motor and exits or manually in the signal for receiving train loaded vehicle dermatomere number signal end
Rotate key switch and disconnect spare motor control loop power supply, motor follows speed reducer to dally, band-type brake with remaining motor internal contracting brake just
Often operation.
Concrete use case：
My company's tippler resets machine and designs 4 motor drivings, contributes as 48 section train loaded vehicle skins.The present invention is served only for more than 48
Vehicle use is led when section, standby electricity electrical-mechanical control loop is individually added to the 5th motor, by being spaced apart, contactor, thermocouple, relay
Composition installs one, contactor additional in outlet, and thermocouple seals in master control circuit, and band-type brake power supply is derived from band-type brake power cabinet, and band-type brake throwing is moved back
Normal operation is controlled by total band-type brake contactor with remaining four motor, is spaced apart and selects 10A, contactor selects 220V 90KW,
Thermocouple selects 110-150A, relay to select 8 leg 220V.PLC logical program operation principles are as follows：Arm is fallen when resetting to reach to stop
When, arm instruction is dealt with, contactor is attracted the spare preparation of the 5th motor and picks up, and resetting machine when tippler after picking up runs to vehicle
When preparing decoupling device in place, hair vehicle signal in place, it is out of service that contactor disconnects the 5th motor, and follow-up 5th motor is with subtracting
The idle running of fast machine, tippler reset machine as usual by four motors driving operations, in order to avoid falling large arm error starting the when unloaded test run
Five motors, in logic large arm being lifted instruction, signal is in parallel in place with vehicle, improves reliability.When dumping to 48 sections or comes
When vehicle is less than 48 section, PLC controls spare motor and exits or manual rotation key in the signal for receiving train loaded vehicle dermatomere number signal end
Spoon switch disconnects the 5th motor control loop power supply, and motor follows speed reducer to dally, band-type brake with remaining four motor internal contracting brake just
Often operation.The 5th motor of this scheme only leads in vehicle to decoupling device short-range in readjustment and uses, on the one hand due in this section
When leading the operation of vehicle low speed, vibration does not increase, and whole shake is not it is obvious that effectively solving to pick up shaking when returning to high-speed cruising
Dynamic problem;On the other hand during permutation vehicle dumping, No. five motor usage times were added up less than 15 minutes, can be met
Demand can have the function that energy-saving, the improved drop energy consumption problem of effective solution again.
It is above disclosed to be merely a preferred embodiment of the present invention, the right of the present invention cannot be limited with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, be still within the scope of the present invention.It should be appreciated that
Above description is intended to illustrative and not limiting.For example, above-described embodiment (and/or its aspect) can be in combination with one another.
