| 发明名称 | DC electrical power system | ||
| 摘要 | A DC electrical power system has a power generator converter system, a positive supply rail extending from the converter system, a negative supply rail extending from the converter system, and a midpoint earthing arrangement operatively connecting to the supply rails. The earthing arrangement is connected to earth by a solid earth connection. The network further has a first protective device on one of the supply rails which in case of a fault is operable to interrupt current flowing on that rail, and a second protective device on the earthing arrangement which in case of a fault is operable to interrupt current flowing to earth through the solid earth connection. | ||

| 主权项 | 1. A DC electrical power system, comprising: a power generator converter system; a positive supply rail extending from the converter system; a negative supply rail extending from the converter system; a midpoint earthing arrangement operatively connected to the positive supply rail and the negative supply rail, the earthing arrangement being connected to earth by a solid earth connection; a first protective device on one of the positive supply rail and the negative supply rail, the first protective device being configured to, in case of a fault, interrupt current flowing on the one rail, and a second protective device on the earthing arrangement, the second protective device being configured to, in case of a fault, interrupt current flowing to earth through the solid earth connection. | ||
