At the beginning of the new year of 2023, the authoritative media Xinhua News Agency and Xi'an TV Station successively paid attention to Xichi Electric - building a high-tech enterprise for industrial automation system solutions.

The identification of "Provincial Enterprise Technology Center" marks that Xichi Electric's research and development capabilities and innovation system construction have reached a new level. We will give full play to the core role of the technology center in promoting technological innovation of enterprises.

Recently, Xichi Electric has won the bids for the Qinling Zhongnanshan Highway Tunnel Project, the China National Petroleum Project and the State Grid Project, respectively, for its three major series of products: soft-start devices, frequency conversion speed control devices and power quality products.

The VFD has achieved remarkable power-saving effect when used in the drive control of fans and pumps. It is an ideal speed control method. It not only improves the equipment efficiency, but also meets the production process requirements, and greatly reduces the equipment maintenance and repair costs, and also reduces the shutdown period.

Over the years, Xichi Electric and universities have carried out many beneficial explorations in cooperation and education, and have in-depth cooperation in many fields such as internship training, entrepreneurship and employment, and transformation of scientific and technological achievements to seek common development.

The harmonic interference phenomenon of the inverter includes: after the inverter starts or runs, the motor overheats, whistles (including increased noise, etc.), and vibrates/vibrates. The motor often breaks down, it is found that the stator insulation of the motor is breakdown after disassembling the motor. The connecting wire between the motor and the inverter will overheat, burst, and even catch fire.

CFV9000A series high-voltage variable frequency speed regulation system, with high-speed DSP as the control core, adopts space voltage vector control technology and cell-series multi-level technology, with high reliability, easy operation and high performance as the design goals, to meet the needs of users for various load adjustments.

We usually refer to the device that converts alternating current with constant voltage and frequency into alternating current with variable voltage or frequency as "frequency inverter". A frequency inverter can also be defined as follows: VFD (Variable-frequency Drive) is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply.

Frequency inverter applied to glass tempering furnace advantages: Low frequency and stable operation during standby, saving energy; The starting current is small, the impact on the power grid and machinery is small, and the service life of the equipment is prolonged; Quick start, shorten the production process and improve production efficiency; Control the frequency required for fast response, and control to meet the production process requirements.
