摘要
通过分析道路照明10kV电源端的接地系统,本文对TN-S系统和TT系统两种接地型式进行了比较和分析,认为类似室外道路照明这些无等电位联结作用的户外场所,低压配电应优先采用TT系统接地型式,可供类似工程参考和借鉴。
Based upon the study of the grounding system at the 10kV power supply terminal,the TN-S system and TT system are compared and analyzed.It is concluded that the TT system should be preferred for low-voltage power distribution in outdoor places without equipotential bonding such as outdoor road lighting,which can be used for reference by similar projects.
