I. Overview
TSF series passive filter compensation device dedicated low-voltage low-voltage power grid in 3, 5, 7, 11, 13 and above harmonic passive filter device. For intermediate frequency smelting, conversion, rolling, rectifier equipment, harmonic changes in the larger places. The device is AC thyristor switching capacitor formed by the series resonant inductor and filter branch, the effective load generated harmonics filter, thus avoiding the harmonic currents back to the power transformers, reducing the amount of harmonic grid, while conducive to safe operation of the transformer to reduce the harmonic power, equipment and other electrical components to improve reliability. In addition, the device also provide a capacity of reactive power compensation to improve the operating efficiency of the user load. Customer demand for each device design, optimum performance of harmonic filtering and reactive power compensation to improve the efficiency of user load, to achieve an effective return on investment.
II. Application
Widely used in electric power, metallurgy, railway, military, petroleum, machinery, chemical industry, port, light industry, building materials, mining, shipbuilding and other supply and distribution systems, a dynamic reactive power compensation and harmonic also need to suppress or control the situation.
III. Role
* Effective support system voltage, the system is running;
* Improve the power factor, reactive power to avoid a fine, while effectively improving equipment utilization;
* Effective harmonic suppression or control;
* Reduce the harmonics and reactive power loss.
Four Technical Features
Zero-current switching ------ own R & D of high-power thyristor current zero crossing switching technology to achieve zero-current investment, removal of zero current, no inrush current, no impact.
Fast dynamic response ---- fast track system load reactive power changes, real-time dynamic switching response, the system response time ≤ 20mS. Unique control strategy ---- the instantaneous reactive power measurement, the proportion of group support a variety of capacitor groups, real-time electricity display system, the system harmonic voltage and current data analysis, waveform display, over current, over voltage, under voltage, three-phase balance, harmonic, multi-temperature digital protection.
Grouping and coding strategies --------- isometric group, small group and compensation to achieve the physical series and more, step away from the fine, excellent value for money.
V. Rationale
1 Dynamic Filter Type
Suitable for containing relatively large number of harmonics of the system, such as DC mill, frequency control systems. TSF device consists of a single tuned filter
As, harmonic filter, while providing reactive power compensation. According to the test industry harmonics generated by the data load operation, or estimated by theoretical calculation + load generated harmonic currents, application-specific design software to calculate the appropriate number of harmonic filter inductance, capacitance parameters and simulation parameters filtering effect, to ensure that resonance The calculation of accurate and safe operation. The device can absorb most of the harmonic currents, thereby improving the system voltage and current harmonic distortion
