Analysis of power distribution cabinets in Shaanxi In recent years, with the rapid development of automatic control systems for industrial and civil boilers, frequency conversion technology has also been widely used in boiler control. The application of frequency conversion technology makes the operation of the entire boiler safer, more efficient, and more energy efficient. It can not only improve the safety and automation of the boiler, but also achieve significant power saving effects. Compared with traditional operation methods, it can save 25% to 40% of electricity and recover costs within two to three heating periods. . In order to meet the needs of the market and users, our company developed the YLBP-2000 boiler control cabinet . It is a set of safe and reliable frequency conversion control device designed for our company's coal-fired boiler. The distinguishing feature of this cabinet is the use of variable frequency to control induced draft fans, blowers, circulating pumps, and make-up pumps, thus replacing the traditional step-down starting method in the past, reducing complex control loops, reducing failure rates, and reducing maintenance costs, saving With manual labor, the impact on the power grid is reduced, and the operating efficiency of the boiler is effectively improved. It should be said that the application of frequency conversion technology is a wise choice for a modern enterprise.
