又来临时抱佛脚了,请教s7a电源问题
书上翻来的吧,说得不好,原话如下,摘自7017-s70 service guide
The filtered 200-240 V ac is then sent to the six system bulk power supplies. The
six supplies are coupled together and provide an N+1 level of redundancy for protection.
N+1 refers to the fact that since the supplies are coupled to a common distribution
bus, if one of the six supplies fails, the system will not fail. The bulk
supplies provide a positive 29 volt output which is fed to the system regulator located
above the bulk supplies and to the system blowers. |
