Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is the soft structural representation that opens integrated device of weight closed loop frequency conversion.
Detailed description of the invention
As shown in Figure 1, the soft integrated device that opens of weight closed loop frequency conversion comprises frequency converter 1, lifting motor 2, the display module 3 of weighing, brake module 4 and wiring terminal 5, the three-phase alternating current input end of frequency converter is connected with three-phase alternating current electric network source, three-phase output end is connected with winder motor 2, wiring terminal 5 is positioned on frequency converter 1, there are the wiring terminal 6 of control loop forward and the wiring terminal 7 of control loop reversion, the power of frequency converter 1 is 30kW, control two winder motors 2, weigh display module 3 and brake module 4 is built in frequency converter, the display module 3 of weighing is made up of LOAD CELLS and the heavy warning device of meter, frequency converter 1 is provided with output fault relay 8 and output frequency detects relay 9, output frequency detects relay 9 can detect forward acceleration frequency, forward deceleration frequency, frequency is accelerated in reversion, reversion deceleration frequency totally four frequencies.
Because detecting relay 9, the output frequency of frequency converter 1 can detect forward acceleration frequency, forward deceleration frequency, reversion acceleration frequency, reversion deceleration frequency totally four frequencies; can regulate according to actual conditions the time of electromagnetism seize; frequency converter output and electromagnetism are put pound cooperation more perfect; descending band-type brake is opened without weightless sense; reduce start/stop machine instant impact; save electric energy, ensure that mine hoist safety is stable, steady comfortable operation.
The built-in display module 3 of weighing of frequency converter 1, LOAD CELLS is directly connected with frequency converter 1, realize the heavy warning function of meter, realize overweight pre-alarm, transship to stop and report to the police, there is very high degree of protection, save weighing controller simultaneously, save cost, and can show that gig promotes the weight of article, according to the automatic regulation output torque of carrying capacity, not horsepower output blindly, more energy-conservation.And had weight judgement to make the gig power that output needs according to actual weight, whole gig traveling comfort is further promoted.
The built-in brake module 4 of frequency converter 1, volume is little, saves cost and installing space, and the regenerative electric energy that lifting motor 2 is produced consumes by braking resistor, keeps DC bus-bar voltage in safe range.
Frequency converter 1 is controlled two each and every one winder motors 2, and this " one drag two " pattern can be carried out parameter of electric machine self study, realizes Current Vector Control, makes gig starting steadily, and the large nothing of moment is slipped hook phenomenon.
Above-mentioned explanation is illustrative rather than restrictive.Can recognize that by above-mentioned explanation those skilled in the art many kinds of the present invention change and distortion, within it also will drop on the spirit and scope of the invention.
