Uhlelo lokuhlinzeka kwamandla amabanga amade lwe-DC

“一线两用”直流远供电源系统是一种基于单线串联拓扑的高压直流远程供电设备。其核心创新在于：利用光电复合缆中的一根铜芯线同时完成直流电能传输与逐级串联供电，实现“一线两用”——既传输直流电，又利用光电复合缆中的光纤传输通信信号，实现电能与信号同缆传输。与传统并联直流远供不同，该系统采用单线逐个串联负载的方式：前端直流高压电源发生器将机房交流电整流、PWM变换为对地悬浮的双极性直流高压电，经单线电缆传

Ukubuka konke komkhiqizo: Uhlelo lokuhlinzeka kwamandla amabanga amade lwe-DC uhlelo lokulethwa kwamandla okukude oludlulisa futhi luthole amandla kagesi we-DC isikhathi eside amabanga ngezintambo zamandla. Uhlelo luqukethe izingxenye ezimbili eziyinhloko: imishini yamahhovisi emaphakathi (iyunithi eseduze) kanye nemishini ekude (iyunithi yokugcina.) Imishini yehhovisi emaphakathi iyanyuka futhi iguqule amandla e-AC noma amandla e- −48V DC avela egumbini lemishini ibe yi-voltage ephezulu DC, okube sekudluliselwa emabangeni amade ngekhebula elihlanganisiwe likagesi noma ikhebula lamandla liye ekugcineni. Ekugcineni, imishini ekude yehlela i-voltage DC ephezulu kuma-voltages ajwayelekile adingwa yimithwalo (njenge-DC 48 V, I-AC 220 V, njll.), ukuhlinzeka ngamandla okuzinzile nokwethenjelwa kwemishini yokuxhumana okukude noma amadivayisi wensimu. Lobu buchwepheshe buyaxazulula
