OTC软件在低压配电柜温升计算中的应用

摘要

通过对IEC／TR 60890低压开关设备和控制设备计算温升验证方法的研究，结合ABB温升计算软件OTC应用实践，帮助设计人员快速地进行配电柜的温升计算、功耗计算及估算风扇排风量，提高低压电气设备的设计选型质量，对于配电柜的设计及低压电器的选型有指导意义。%A method of temperature⁃rise verification of low⁃voltage switchgear and con⁃trolgear assemblies according to IEC/TR 60890 is reaseardzed , based on ABB software OTC ( Over Temperature Calculation) experience gained from projects, which helps de⁃signers to easily calculate the temperature rise, power consumption and estimate the fan exhaust air volume, and improves the qulity of design and selection of low⁃voltage eletrical equipment. It has reference significance for low⁃voltage switchgear and controlgear’ s se⁃lection.
