摘要
对某铜冶炼厂10 k V变电所的保护装置进行了分析,并依据《工业与民用配电设计手册(第三版)》第四章、第七章内容提出了一套整定值计算方法。此方法不仅适用于有色冶炼行业,也适用于其它工矿企业。并以此为例介绍了继电保护整定值的计算方法和步骤以及在某铜冶炼厂的应用。
In this paper, the protection device of a copper smelting plant with 10kV substation is analyzed, and a set of calculation method is presented according to chapter 4th and 7th of 《Handbook of industrial and civil power distribution（3rd Ed）》. This method is not only suitable for non-ferrous smelting industry, but also for other industrial and mining enterprises. Taking a copper smelting plant as an example, this paper introduces the calculation steps and method of the relay protection setting value.
