Product Overview of Simo Motor's SBB2 Series High - Voltage Reactive Power Compensation Cabinet

Simo Motor's SBB series high - voltage reactive power compensation cabinets are mainly used in 6kV - 10kV power systems. They serve as reactive power compensation devices to improve the power factor, adjust the voltage, and reduce network losses.


Most of the loads in the power system are inductive. Additionally, with more and more industrial and mining enterprises using power electronic equipment, the power factor of the power grid is very low. A low power factor reduces the equipment utilization rate, increases power supply investment, impairs voltage quality, shortens the equipment service life, and increases line losses.


To improve these unfavorable production factors caused by the low power factor of the power grid, the power factor of the power grid must be effectively increased. Obviously, it is neither reasonable nor usually possible for all this reactive power to be provided by the generator and transmitted over long distances. A reasonable approach is to generate reactive power where it is needed. In an actual power system, most loads are asynchronous motors. Their equivalent circuit can be regarded as a series circuit of resistance and inductance, with a large phase difference between voltage and current and a low power factor. After connecting a shunt capacitor, the phase difference between voltage and current becomes smaller, thereby increasing the power factor.

Performance Characteristics of Simo Motor's SBB2 Series High - Voltage Reactive Power Compensation Cabinet

  1. Select well - known and high - quality components and adopt advanced design, ensuring a long product service life.
  2. With a reasonable layout and user - friendly design, it is convenient to operate, use, and maintain.
  3. It is equipped with a built - in discharge device to ensure the safety of personnel and equipment.
  4. It has multiple protection functions such as open - delta protection, over - current protection, and over - load protection, making the operation safe and reliable.
  5. It uses vacuum - electroplated metallized polypropylene film shunt capacitors, which have low self - losses. This is because polypropylene film features a high working field strength, low dielectric loss, small size, large capacity, low loss, and light weight.
  6. The deviation between the measured capacitance of the capacitor and its rated value does not exceed +10% - 5% of the rated value.
  7. A series reactor can be added to limit the inrush current during the capacitor switching process, restrict the switching over - voltage, and suppress the influence of high - order harmonics in the power grid on the capacitor.
  8. The power - saving effect is obvious. It can increase the power factor of the power grid to over 0.95, reduce the current by 10% - 20%, and effectively reduce line losses.
  9. It has low self - losses. The energy loss of the capacitors used in this device is extremely small, being less than one - fifth of that of general oil - immersed low - capacitance capacitors.
  10. Fully considering the actual situation of users, the capacitor bank and relevant control components of the on - site compensation cabinet are placed in the same cabinet, which is convenient for on - site compensation of single high - voltage motors.
