Induction melting furnace harmonic elimination cabinet Rationale

Inductive melting furnace harmonic elimination cabinet TQF type harmonic elimination reactive power automatic compensation device adopts special test equipment and technology according to the user load condition, and provides users with reactive power compensation and harmonic comprehensive management device for eliminating harmonics. Strong, safe and reliable, reactive power compensation and harmonic control are carried out at the same time, and the economy is good, and has been widely applied to non-linear load users such as rectification and metallurgy.

Induction melting furnace harmonic elimination cabinet adopts technology

Inductive melting furnace harmonic elimination cabinet TQF type harmonic elimination reactive power automatic compensation device mainly has the following technical features: 
● Adopting a comprehensive switching strategy of reactive power, voltage and power factor, avoiding switching oscillation and reversing reactive power to the grid;     

● With over voltage and under voltage limit setting function, it is conducive to grid voltage adjustment; 

● It has effective monitoring and over-limit protection function for grid harmonic voltage and current; 

● Calculate actual capacitor capacity according to actual voltage, and the compensation effect is more Accurate; 

● The effect of suppressing harmonics meets the requirements of national standards; 

● The power factor is controlled between 0.95 and 1.0.  

Induction melting furnace harmonic elimination cabinet control technology

The multiple groups are automatically input, and the DHK-II type harmonic elimination reactive power automatic compensation device is fully controlled, which can automatically track the load and ensure the best compensation effect and safe and stable harmonic elimination measures under various operating modes. The grouping method "full consideration of the characteristics of the load, and to ensure the minimum harmonic filtering safe operation. 
Filter technology: TQF type harmonic elimination reactive power automatic compensation device according to the user's use, after careful analysis and calculation, give the best configuration The filter capacitor is specially selected by our company. The special reactor for the harmonic elimination series reactor is produced by the company. The parameter performance is stable and the single component quantity is reasonable.

Inductive melting furnace harmonic elimination cabinet reactive power compensation technology

The DHK-III type control technology can ensure that the power factor (COSΦ) is maintained above 0.95, so that the user can get the best power rate to adjust the electricity fee, fully reduce the line loss, and save the electricity cost by more than 20%.

Inductive melting furnace harmonic elimination cabinet harmonic elimination compensation effect

Harmonic control effects meet national assessment standards, eliminating harmonic interference to other equipment and control systems, power factor (COSΦ) increased to above 0.95, usually maintained at 0.98 to ensure maximum power savings.
