CN105449844A 一种并联用智能电池模块供电系统 无效 - 驳回

一种并联用智能电池模块供电系统
摘要：
本申请提供一种并联用智能电池模块供电系统，包括：输入端与电网相连的并联用智能电池模块组，所述并联用智能电池模块组的输出端与馈线支路相连；一端与所述馈线支路相连的馈线开关，所述馈线开关的另一端与负载相连；一端与所述馈线支路相连，另一端接地的辅助电容，所述辅助电容用于当所述并联用智能电池模块组无电流输出时，提供能够保证所述馈线开关脱扣的故障电流。当若所述馈线支路中发生短路导致所述并联用智能电池模块组停止供电后，所述馈线开关仍未脱扣时，所述辅助电容会向所述馈线支路提供故障电流，从而保证了所述馈线开关在无需所述并联用智能电池模块组供电的情况下，能够正常执行脱扣操作。
摘要（英）：

The application provides a power supply system for a parallel smart battery module. The power supply system comprises a parallel smart battery module set, a feeder switch and an auxiliary capacitor, wherein the input end of the parallel smart battery module set is connected with a power grid; the output end of the parallel smart battery module set is connected with a feeder branch; one end of the feeder switch is connected with the feeder branch; the other end of the feeder switch is connected with a load; one end of the auxiliary capacitor is connected with the feeder branch; the other end of the auxiliary capacitor is grounded; and the auxiliary capacitor is used for providing failure currents capable of ensuring tripping of the feeder switch when the parallel smart battery module set has no output currents. When the short circuit occurs in the feeder branch to cause cut-off of supply of the parallel smart battery module set and the feeder switch still does not trip, the auxiliary capacitor can provide the failure currents to the feeder branch, as a result, the fact that the feeder switch can normally trip under the condition of not being powered by the parallel smart battery module set is ensured.
