Converter dust removal is the key link of converter steelmaking, and the transmission equipment is the transportation artery of the dust removal fan system, so the stability of the transmission equipment plays a vital role in the normal operation of the blower.
Long-term operation without problems.
The inverter has a bypass function, which can make the motor switch to run in case of a fault to ensure that the equipment does not stop.
The speed range is large and the power is high.
There is a resonance point jump setting, which can make the motor run away from the resonance point and the fan will not surge.
In order to complete the four requirements of the dust removal fan and take care of the heart of the dust removal equipment, INVT launched the GD5000 inverter + GD5000-MS four-to-three manual bypass system solution, which has the following outstanding advantages:
1. Each inverter can choose to drag one of the three motors, which is more flexible to use.
2. When one of the inverters is faulty, the designated other inverter that is not faulty and not running continues to start the motor, insisting that the fan runs in the frequency conversion condition to save energy and reduce consumption.
The value that INVT's solutions bring to customers
1. High reliability: real-time monitoring of the operation of the power unit, timely supply of fault prediction, to ensure the reliable operation of the equipment. In the 24H operation mode, the system can continue to operate after a unit bypass by 8%.
2. High power, energy saving and consumption reduction: the power is as high as 96% above 20% load, the equipment operation frequency is about 35Hz-45Hz, and the energy saving and consumption reduction are 25% to 40%.
3. Reduce the cost of protection: reduce the mechanical impact on the motor and fan bearings and fan blades, reduce the cost of protection, and improve the service life
After on-site use, four inverters were completed to drag three motors for three purposes and one standby operation, and the inverters were backup to each other, which completely solved the problem of production suspension caused by faults.
INVT has been deeply involved in the steel industry for more than 10 years, is committed to building full-process electrical drive solutions for steel, supplying high, medium and low voltage inverters and SVG, UPS, servo, PLC, optical storage and charging and other rich special products for the steel industry, which are widely used in the whole process of steel process equipment, with a total of more than 300 service industry users at home and abroad, and have good cooperation with large-scale general contractors, system integrators and OEMs, and adhere to the implementation of the industry import substitution strategy, continue to lead the localization of all walks of life.
