中频电炉智能化是中频电源的发展趋势,也是衡量中频电炉电源 性能先进性的重要标志;同时中频电炉电源智能化也是提高加热处理自动化程度和电源可靠性的要求,使电源趋向集成化、模块化,对缩短生产周期,提高可使用性和可维修性均有重要意义。 Intelligent medium frequency electric furnace is the development trend of medium frequency power supply, and measure the important symbol of intermediate frequency electric stove power performance is advanced; And intermediate frequency electric furnace intelligent power supply is also increasing the degree of automation and power supply reliability requirements, make power toward integration, modularity, to shorten the production cycle, improve the reusability and maintainability are of great significance. 中频电炉电源实现智能化,应着重解决以下问题。 Intelligence of intermediate frequency electric furnace power supply, the following problems to be solved. (1)选用智能半导体模块是实现智能化的基础。构成中频电炉逆变器的电力半导体功率器件模块智能化,是加热电源智能化的基础。为此应选用集驱动控制、保护、智能于一体的智能模块,这些低电感、多功能、高集成的电力半导体模块,不仅减小了体积、质量,提高了逆变器在高频工作下的效率和可靠性,而且为采用微处理接口,实现智能化控制奠定了基础。 (1) selection of intelligent module is the basis of the intelligence of semiconductor. A medium frequency electric furnace intelligent inverter power semiconductor power device module, is the foundation of the intelligent heating power. Should be chosen for this collection drive control, protection, intelligent in a body's intelligent modules, these low inductance, multi-function, high integration of power semiconductor module, not only reduces the volume and quality, improve the efficiency and reliability of the inverter under high frequency work, and for the microprocessor interface, which laid a foundation to realize intelligent control. (2)运用数字处理技术是实现智能化的核心。中频电炉电源的控制技术是否先进合理,是决定加热电源智能化程度的关键。早期中频电炉电源的控制电路采用模拟电路,难以实现智能化,而且模拟电路受温度影响和抗干扰性差,导致参数不稳定和可靠性变差。运用单片机控制,使中频电炉电源向智能化方向迈进了一大步。现在应用数字信号处理器(DSP),信息容量更大,处理能力更强、更灵活,整个控制电路可用一片DSP完成,实现自动化智能控制。 (2) the use of digital processing technology is the core to realize intelligent. Intermediate frequency electric stove power control technology is advanced and reasonable, is the key to decision heating power intelligent degree. Early of intermediate frequency electric furnace power supply control circuit adopts analog circuit, it is difficult to realize the intelligent, and analog circuits are influenced by temperature and poor anti-interference and deterioration in unstable parameters, and reliability. Using single-chip microcomputer control, the intelligent direction of intermediate frequency electric furnace power supply is a major step forward. Application of digital signal processor (DSP) now, information capacity is bigger, processing ability is stronger, more flexible, the control circuit can be used a piece of DSP, complete intelligent automation control.
