摘要
提出了在大型铜冶炼厂中压系统采用一种新型的接地方式——与专用选线技术相配合的消弧及过电压保护装置接地系统,它可有效限制弧光接地过电压,选线准确率高,可提高企业供电系统的可靠性和连续性。同时简述了该装置的结构、工作原理及应用实践,指出使用该装置的注意事项。
The paper put forward a new type of grounding mode that is to be applied in the medium voltage system of large copper smelters, i.e. the arc-extinguishing overvoltage protection grounding system combined with the special selecting line technology. It has high accuracy of line selection and can effectively restrict the arc grounding overvohage and improve the reliability and continuity of enterprise＇ s power supply systems. The paper also introduced the structure, operating philosophy and application of the system as well as precautions in application of the system.
