Power regulator thyristor is an abbreviation of thyristor rectifier. It is a high-power semiconductor device with a four-layer structure with three PN junctions, also known as a thyristor. It is one of the more commonly used semiconductor devices due to its small size, relatively simple structure, and strong functions. It is the perfect combination of thyristor AC switching technology and transformer technology. Using high-power thyristor thyristor instead of mechanical and carbon brushes to control the voltage regulation, the capacity can be 2000kVA, the compensation range can reach up to ± 50%, and the efficiency can reach more than 99%, which is leading the development of high-power power regulators. The advanced products of the direction are energy-saving green products, with all protection functions, very reliable work and strong adaptability. Realized full contactless voltage regulation, which has the advantages of good stability and high efficiency, no pollution to the power grid, reliable and continuous work under a variety of harsh power grids and complex loads, extremely long service life, and continuous and trouble-free Running for more than 100,000 hours, the long-term maintenance-free operation of the regulator is realized.
In the early days of the SCR regulator, due to the immature semiconductor structure of the DISC, the discharge voltage of the SCR regulator was determined by the DB3 voltage. The life of the SCR regulator was longer, but the current energy was smaller and the switching speed was slower. It is more suitable for high-pressure sodium lamps, and not suitable for occasions where the pulse width of metal halide lamps is required. The structure can be improved but the cost is higher.
The power regulator adjusts the level of the rectified voltage to control the feeding amount of the electromagnetic vibration feeder. Feeder adopts thyristor regulator to rectify power supply, change the conduction angle of thyristor regulator, you can control the level of output voltage, according to the use conditions, different signals can be taken to control the size of the conduction angle of thyristor regulator In order to achieve the purpose of automatic quantitative feeding, the accurate control of the feeding of the electromagnetic vibration feeder directly affects the efficiency and quality of production. The electromagnetic vibration feeder can be controlled to uniformly feed. It has a simple structure, easy adjustment, stable work and long distance. Microcomputer control and other features can achieve centralized control and automatic control of the production process.
