摘要
为满足特殊工程需要配备大量高压供电系统下的起重机械,针对此类供电系统的特点,结合不同小电流接地系统的特点,以及发生单相接地故障所采取的接地选线方式,对应用范围广、可靠性高的选线方式做了典型分析,有助于高压供电系统的起重机使用单位正确选择合适的接地接线方式。
In order to meet needs of special projects with a large number of hoisting machinery powered by high-voltage power supply system,considering characteristics of this kind of power supply system,combining with characteristics of different lowcurrent grounding systems and the grounding line selection methods adopted in case of single-phase grounding fault,typical line selection methods with wide application range and high reliability are analyzed,which is helpful for users with cranes powered by high-voltage power supply system to correctly choose the appropriate grounding connection methods.
