Product Introduction

Overview

BW-HTSF series step-down high-voltage dynamic reactive power compensation device, through the step-down transformer to reduce the compensation system voltage to 0.4kV or 0.66kV, the low-voltage TSF reactive power compensation filter device is connected to the system device. This device avoids overvoltage and inrush current during the switching process of high-voltage capacitors, prolongs the service life of capacitors and switches, and comprehensively improves the overall quality level of the power supply system. For dynamic compensation of small capacity, it is a cost-effective compensation scheme.

Products are widely used in metallurgy, coal, chemical, nonferrous metals, petrochemical, semiconductor, automotive and other industries.

Working principle

The step-down type is relative to the direct hanging type, and the main difference is in the intermediate link. The whole machine is connected to the high-voltage bus system side by connecting the reactor and disconnector. The step-down model is connected to the high-voltage bus by a step-up transformer and disconnector.

The system is shown in the figure:

Technical characteristics
  • Using thyristor switching capacitors, the controller detects the power factor and reactive current in real time, compares it with the preset fixed value, and dynamically controls the switching of different groups of capacitors;

  • Avoid the reactive power impact of inrush current and overvoltage on the system generated during capacitor switching;

  • Avoid problems such as arc pulling and contact aging caused by the use of vacuum switches;

  • Dynamic tracking and timely compensation with the reactive power change of the system;

  • Small switching step distance and high compensation accuracy;

  • Simple structure and high maintainability;

  • Upgraded products, a wide range of application prospects, especially in the case of output capacity less than 1M, has obvious market advantages.
