Introduction

  • Due to the improvement of industrial automation, rectifier equipment, frequency converters, electrolyzers and electric arc furnaces are widely used in industrial and mining enterprises. These non-linear loads produce large amounts of High-order harmonics are injected into the power grid, causing distortion of the power grid waveform, resulting in deterioration of the quality of the power grid, and Threaten the safe operation of other electrical equipment in the power supply system. This kind of "electricity "Power pollution" can cause additional losses in transformers, cables and other power devices; In order to make the control, protection and measurement system function abnormal, communication and network are also disturbed.
  • HVPF series high voltage passive filter compensation device is the best way to solve voltage and current distortion Method, the device is mainly used to control harmonics and also for reactive power compensation, not only makes the system harmonics The voltage distortion rate and the harmonic current flowing into the grid meet the requirements of national standards, and it can Improve the power factor to achieve the dual purpose of governance and energy saving.

Feature

  • According to the system impedance, power and harmonic parameters, the computer simulation software is used to simulate the design to determine a reasonable filter branch and installation capacity to ensure the superior and reliable solution
  • The filter capacitor is made of full-film insulating medium, which has the characteristics of small size, low loss, low operating temperature, and strong overload capacity.
  • The filter reactor adopts single-phase air-core reactor, the reactance value is continuously adjustable within ±5%, and the operating noise is low;
  • the resistor adopts non-inductive or micro-inductive resistor, and the resistance value is adjustable in stages to ensure the accuracy of the tuning point and the filtering effect
  • The complete set of equipment is equipped with a live display and an electromagnetic compulsory locking link to ensure the safety of the operating personnel
  • For the occasions with high power factor and high harmonic current, a reactor connected in parallel with the filter capacitor can be added to form a high-order LC circuit to make the power frequency current close to zero, while still presenting at high harmonic frequencies Low impedance to achieve "zero reactive power" filtering function
  • The structure of the complete set of equipment is flexible, there are frame type and cabinet type, and can be designed according to the user's actual site
