摘要
根据相关国际标准和我国标准,阐述通信电源接地系统设计新观念和实施原则,介绍通信局(站)交流和直流配电系统的接地技术,包括低压交流配电系统、UPS、高频开关电源和高压直流配电系统的接地方法。此外,还分析了当前实际工程中存在的问题,并提出改进建议。
According to related international standard and domestic standard, new concept of earthing system for telecommunication power supply and implementation principles are described. The technologies of AC and DC power system earthing, including earthing methods for low voltage AC distribution system, UPS, high frequency switch mode power supply, and higher voltage DC power feeding system etcs., are introduced. Furthermore the present problems in practical engineering are analyzed and suggestions are given.
