摘要
TN-C-S系统的中性线电流由于PEN线的重复接地,会通过引入同一建筑物的其他回路的PEN或PE线返回电源,产生分流,导致本回路和其它回路产生剩余电流。该剩余电流会引起涡流损耗、磁滞损耗和短路环损耗。
Due to the repetitive grounding of PEN lines, the current in the neutral line of the TN-C-S system will return to the power source through the PEN or PE lines of other loops introduced into the same building, generating divided currents and resulting in residual currents in its loop and other loops. The residual currents can cause vortex loss, hysteresis loss and loss of short- circuit ring.
