How to choose frequency conversion series resonance?
Nowadays, a lot of power industry related manufacturers will use series resonance tester, so we must compare and inspect the market of series resonance sales. Here, Zhizhuo measurement and control recommends you to choose famous large factories, so that they will have mature technology research and development, product design and production, and perfect one-to-one after-sales service. You can also come to the factory for on-site investigation in person, and make your choice after your comprehensive investigation. With the manufacturer to look at the product, specifically understand the performance and technology of the product.
Series resonance tester, frequency conversion series resonance device is mainly composed of frequency conversion controller, excitation transformer, high-voltage reactor, high-voltage voltage divider, etc. The frequency conversion controller is divided into two categories, 20kW and above is the control desk, 20kW and below is the portable box type; it is composed of controller and filter. The main function of frequency conversion controller is to change 380V or 200V power frequency sinusoidal alternating current with fixed amplitude and frequency into sinusoidal wave with adjustable amplitude and frequency. And provide power for the whole set of equipment. The function of the excitation transformer is to raise the output voltage of the variable frequency power supply to the appropriate test voltage. High voltage reactor L is an important part of resonance circuit. When the power frequency is equal to 1 / (2 π√ LCX), it will have series resonance with test object Cx.
When you have a complete understanding of the manufacturer's environment and equipment, you will know how to choose. You can discuss the specific technical parameters with the manufacturer's technical personnel. I think you should know how to choose series resonance!
