煤炭工业在技术改造、推行生产过程综合机械化与自动化的基础上的发展,与改进矿山企业供电系统、提高其技术经济效果密切相关。矿井供电可靠性不足,会导致大量经济损失。 提高系统元件的可靠性,保证保护装置动作的选择性,采取防止保护装置误动作的措施,以及采用备用供电线路、备用线路自动合闸装置和重接系统等,都能提高矿井供电的可靠性。 “可靠性”的概念与“效果”的概念不
The development of coal industry on the basis of technological transformation and the implementation of comprehensive mechanization and automation in the production process is closely related to improving the power supply system of mining enterprises and improving their technical and economic effects. Inadequate reliability of mine power supply can result in significant economic losses. Increasing the reliability of system components, ensuring the selectivity of protection devices, adopting measures to prevent misoperation of protection devices, and using backup power supply lines, automatic line closing equipment for backup lines and reconnection systems all can improve the reliability of mine power supply . The concept of “reliability” and the concept of “effect” do not
