Product Overview
The intelligent tuning compensation device -HRDQ-ZHL is designed for situations where the power consumption network has a certain harmonic content and ordinary intelligent power capacitors cannot operate normally. Its main features are as follows: It adopts high-quality industrial-grade low-voltage power capacitors, with an oil-free design and high safety. It adopts inrush current switching switch, which is technologically advanced and has stable and reliable performance. It adopts a closed-loop circuit, with an unsaturated magnetic field, no energy consumption and no electromagnetic radiation. By adopting special technologies and processes, it can effectively suppress high-order harmonics and inrush currents, and the effect on suppressing harmonics above the 3rd, 5th, 7th, and 9th orders is particularly remarkable. Modular structure, flexible combination, convenient expansion, simple installation and easy maintenance. Intelligent network, 485 communication interface, can be connected to the computer background for comprehensive power distribution management. It adopts a decentralized control mode, with 1 million trouble-free switching operations and high reliability. The humanized human-machine interface is simple to operate, convenient to maintain and conducive to on-site fault location. The product is equipped with an explosion-proof device and a temperature control device inside, which enhances the reliability of operation under severe harmonic fields. It has a remarkable energy-saving effect, effectively improving the power factor, reducing power consumption and enhancing power quality.
The intelligent tuning compensation device -HRDQ-ZHL is mainly applied in places where the harmonic current is below 50% (such as frequency converters, submerged arc furnaces, magnetizing machines and other equipment), effectively suppressing high-order harmonics and insurges, and forming a low-impedance path for high-order harmonics. It has the function of absorbing and discharging harmonics, can eliminate the influence of high-order harmonics on capacitors, protect circuits and capacitors from overload, prevent capacitors from overheating, aging of insulating media, decline in self-healing performance, and reduction in service life, etc. It can not only meet the requirements of reactive power compensation and improve the power factor, but also eliminate the influence of high-order harmonics on the system and enhance the quality of power consumption.
