摘　　要：固化工艺在干式变压器高压线圈制造过程中扮演着关键角色。其中一个关键问题是如何准确控制固化炉内的温度。不过由于传统的通断式温度控制方式具有制作简单且容易实现的特点,目前仍被广泛应用于干式变压器生产企业。然而,由于无法对加热电流进行连续调整,传统方式难以实现对固化炉内温度的精确控制。为解决该问题,我们采用调功器控制技术来改进干式变压器固化炉的温度控制。实验结果表明,相较于传统的通断式温度控制器,调功器的温度控制精度误差基本在±1℃以内,而且研究结果还表明,调功器控制的固化炉,能够降低单组产品的累计能耗26.5%。这为固化炉温度控制领域提供了一种可行且优越的技术选择。Curing process plays a key role in the high voltage coil manufacturing process of dry transformer.One of the key problems is how to accurately control the temperature in the curing furnace.However,because the traditional on-off temperature control method is simple and easy to implement,it is still widely used in dry-type transformer manufacturers.However,because the heating current cannot be adjusted continuously,the traditional method is difficult to achieve accurate control of the temperature in the curing furnace.To solve this problem,we use power regulator control technology to improve the temperature control of dry transformer curing furnace.The experimental results show that compared with the traditional on-off temperature controller,the temperature control accuracy error of the power regulator is basically within±1℃,and the research results also show that the power regulator controlled curing furnace can reduce the cumulative energy consumption of a single group of products by 26.5%.This provides a feasible and superior technical choice in the field of curing furnace temperature control.
