广州地铁直流牵引供电中馈线热力过负荷保护

The Thermal Overload Protection In DC Traction Of Guangzhou Metro

本文阐述了热过负荷保护的原理及推导过程,在充分理解DPU96保护模块中热过负荷保护各个参数的意义后,把各参数转化成热力过负荷的通用公式中的参数,建立起DPU96热过负荷保护的运算模型并验证该模型的准确性,为准确校验该保护提供了依据,也使设备运行人员更好的理解了该保护的意义。

This adcle describes the thermal o verloadprotection principleand the derivationprocess, in filll understan dingofDPU96 protection module thermal over load pro tection parameters meaning, each parameter is transformed into thermal overload of general parameters in the formula, establish es the DPU96 thermal over load protection operation model and verify the accuracy of the model, for accurate check the protection provided a basis also make the equipment operationandbetter understandingofthe significance oftheprotection.
