The products are detailed:

Product introduction:
HPVFS separate explode and person who fit frequency converter our company collect frequency conversion transfer the intersection of speed and technology and anti-blast technology of electricity in the integrative high-tech products originally, Yes four quadrants run, suitable for, exchange 50/60Hz, specified the intersection of voltage and asynchronous the intersection of motor and heavy load of 660/1140V carry on one’s shoulder or back soft to start, not soft to park and run course transfer the intersection of speed and energy-conservation, control, have many kinds of control and protect the function, mainly apply to colliery’s exploding and containing in dangerous place and other mediums around in the explosive gas environments of methane and coal dust mixture in the pit. This device is by brand-new design circuit, frequency conversion technology, vector control technology and through exploding and safe practices essential,etc. combine together, have the advantage of being exclusive and technological. Frequency converter this can four quadrant run, have energy repay function, energy-conserving result obvious; Have low-speed high torque, complete torque characteristic; And many kinds of control modes. In the field of properties of product and particular application, have reached the characteristic products really fitting user’s requirement.

Main characteristic:
1.Can regenerate, control, when it is used on the system that the inertia load or hoist employs but 70~90% energy-conservation;
2.Can control unit power in factor ” 1″ ( cosφ ≈ 1);
3.The harmonic wave is controlled and reduced to less than 2% at most;
4.Many motors drive the control device;
5.Change and turn towards and moderate and control the function;
6.Stop the torque and control the function: Under stopping the state, 150%-200% of the torque can take place;
7.Tune the function up automatically;
8.Various function and flexibility is started;
9.Various parameter editors and controlling the hold function of the data (in 24 hours before trouble) in real time ;
10.The mistake chases the mark function;
11.The high-efficient trouble solves the function: Various control variables such as the first input voltage, electric current, frequency, input power, temperature of second takes place and follow and break the data to record the function to keep the trouble.

Main performance parameter:
1.Input the voltage 660/1140V AC of the power, & plusmn of fluctuating range; 10%
2.Frequency 50/60Hz, & plusmn of fluctuating range; 10%
3.Power grade 5.5kW ~630kW
4.Add the time of moderating 0~3000s
5.Frequency of the signal carrier 0.8~10kHz can be regulated automatically
6.The power factor can be presumed(such as cosΦ =1)
7.Start the torque: There is no sense vector to control, 150% (0.5Hz)
The thoughts vector is controlled, 200% ( 0Hz)
8.Basis frequency: Imitate I/P: 10 resolution ratios, precision & plusmn; 0.1%
The joining value of panel: Resolution ratio 0.01Hz/0.1Hz
9.Accelerate time: V/F controls: -0.5 3000.0[sec]
There is not sense & that have a sensor vector to control: -0.00 3000.00[sec]

Employ the occasion:
This product is used mainly in the colliery or the open-air mine in the pit, port quay, heave- load of selecting coal worksing, power planting,etc. transporting equipment soft to start, not soft to park and run course control in the abominable environment, and the bringing control of conveyer, scratch board conveyor, coal feeder, air blower, water pump and oil pump,etc. apparatus in the pit of colliery.
