电力分配系统和操作电力分配系统的方法
摘要：
一种电力分配系统(100)，包括：第一电路保护装置(124)和第二电路保护装置(128)，第二电路保护装置(128)在所述第一电路保护装置的下游联接到第一电路保护装置。第二电路保护装置包括跳闸机构(114)和跳闸单元(110)，跳闸机构配置成中断通过第二电路保护装置流动的电流；跳闸单元操作性地联接到跳闸机构。跳闸机构配置成对于第二电路保护装置，确定保护阈值(216)和低于该保护阈值的闭锁阈值(214)；在判断出电流超过闭锁阈值时，将前向闭锁信号(160)传输到第一电路保护装置；以及在判断出电流超过保护阈值时生成反向闭锁信号(161)。
摘要（英）：

A power distribution system includes a first circuit protection device and a second circuit protection device coupled to the first circuit protection device downstream of the first circuit protection device. The second circuit protection device includes a trip mechanism configured to interrupt a current flowing through the second circuit protection device, and a trip unit operatively coupled to the trip mechanism. The trip mechanism is configured to determine, for the second circuit protection device, a protective threshold and a blocking threshold that is lower than the protective threshold, transmit a forward blocking signal to the first circuit protection device upon a determination that the current exceeds the blocking threshold, and generate a reverse blocking signal upon a determination that the current exceeds the protective threshold.
