摘要：
本发明公开了一种配电终端跳闸回路的保护方法，包括配电终端、一次开关、一次开关操作回路、跳闸空接点和合闸空接点，配电终端的跳闸输出端与一次开关的跳闸输入端连接，配电终端的输出端分别与跳闸空接点和合闸空接点的输入端连接，跳闸空接点和合闸空接点的输出端与一次开关操作回路的输入端连接，一次开关操作回路的输出端与一次开关的输入端连接，利用一次开关操作回路中的电阻减小一次开关中的电流，保护一次开关。本发明通过设定一次开关一次开关操作回路，能够有效的延迟电路中电流的流动时间，能够及时的保护一次开关；本发明具有结构简单、使用性能稳定和使用寿命较长的优点。
摘要（英）：

The invention discloses a protection method for a trip loop of a distribution terminal. The distribution terminal, a primary switch, a primary switch operation loop, a tripping air contact and a closing air contact are involved in the method, wherein the tripping output end of the distribution terminal is connected with the tripping input end of the primary switch; the output end of the distribution terminal is connected with the input ends of the tripping air contact and the closing air contact respectively; the output ends of the tripping air contact and the closing air contact are connected with the input end of the primary switch operation loop; the output end of the primary switch operation loop is connected with the input end of the primary switch; the current in the primary switch is reduced by the resistance in the primary switch operation loop so that the primary switch is protected. According to the protection method, the flowing time of the current in a circuit can be delayed effectively by arranging the primary switch and the primary switch operation loop, and the primary switch can be protected in time. The loop has the advantages of simple structure, stable using performance and long service life.
