With the continuous rise of human capital costs, more and more companies in various fields have begun to introduce automated production lines to achieve automated processing, assembly and testing. Some mechanical standard parts are manufactured using automated production lines.
The process of automatically operating or controlling an automated production line according to prescribed procedures or instructions without intervention. Its goal is “stable, accurate and fast”. Automation technology is widely used in industries such as industrial production, agriculture and animal husbandry, national defense, scientific research, transportation, business services, diagnosis and treatment, services and households. The selection of automated assembly lines can not only liberate people from complicated physical work, some mental work and extremely risky office environments, but also expand the functions of internal organs, further improve labor efficiency, and improve people’s ability to understand and transform the world. Although the automated production line saves labor costs and improves production efficiency, at the same time, the company needs to deal with the harmonics generated by the automated production line equipment.
Harmonic pollutants are complex and changeable. There may be harmonics caused by itself, harmonics from the high voltage grid or harmonics caused by common users on the same bus.
The harm of harmonics to high-precision equipment. There are many high-precision machinery and equipment in the driving force application of the laboratory or automated production line.
In many cases, this equipment, the generator set, is a victim of pulsating currents. Harmonics will endanger the normal operation of laboratory equipment, so that the tests carried out can not meet the requirements. Harmonics can also affect the intelligent controller and program controller system software of the automatic production line, causing failures in the automatic control system equipment. In many of our company-level laboratories, automatic production lines of cigarette minting companies, and automatic production lines of paper industry companies, mechanical failures caused by overpulse currents have occurred.
User Value of Harmonic Governance
Reduce the harm of harmonics, prevent the working voltage caused by harmonics from increasing and destroying various common faults such as electrical equipment, and improve the safety factor of the power supply system.
Govern harmonics, reduce harmonic current injected into the system, and meet our company’s standard requirements;
Dynamic compensation for reactive loads, qualified power factor, and prevention of penalties from power supply companies.
Problems you may encounter?
1. The production line uses a lot of AC motor speed control equipment and motors, which leads to the internal pulse current environmental pollution and power quality safety hazards in the company;
2. Harmonics are complex and changeable, difficult to manage, seriously affecting the normal and safe operation of electrical equipment in the production line
3. Traditional reactive power compensation equipment is often damaged, and even causes harmonics to become larger.
Our solution:
1. According to the pulse current status of the system, the flow reactance rate is reasonable, and the static data security compensation equipment is selected to compensate the reactive load of the system and improve the system power factor;
2. Use the active filter Hongyan APF to manage system harmonics, and reduce the content of system harmonic currents to below the limit value required by our company’s standards
3. Adopt Hongyan series passive filtering device, design LC tuning parameters, compensate reactive power while managing system characteristic harmonics, and improve power factor.
4. Hongyan series dynamic var generators are used to dynamically provide reactive power to each phase of the system and process all harmonics of the system at the same time.
