The tie bbreaker had to be unique so there was a need to deduplicate the entries to remove multiple matches (due to a quaint little law where if you awarded a prize to one person based on their tie breaker and somebody else could prove they had entered with the same tie breaker, then you had to award them the prize as well; providing they satisfied all other prize winning criteria).

在决胜局必须是唯一的，因此有必要进行重复的项，删除多个比赛（由于小巧奇特的法律：如果你获得一个奖，一个人在他们的配合断路器和别人的能证明他们已经进入同样的决胜局，那么你必须给他们颁发奖金，以及，提供他们满意的所有其他奖的标准）。

Via checking, affirm Nanjing all directions 100 million can the company debugs an engineer to be in to pyroelectricity line of 8 total mix measures gold of one station 10KV in accusing what accept supervisory system partly to debug a process, did not check seriously equipment name, also did not get tutelar personnel to affirm, do sth without authorization has the operation dividing brake of breaker, in will moving by accident advocate change 3-10KV breaker is pulled open.

经查，确认南京四方亿能公司调试工程师在对热电一站10KV金8总调线路测控部分接入监控系统的调试过程中，没有认真核对设备名称，也没有得到监护人员确认，擅自进行断路器的分闸操作，误将运行中的主变3-10KV断路器拉开。

Time graded schemes such as over-current or distance protection schemes are examples of those providing inherent back-up protection; the faulty section is normally isolated discriminatively by the time grading, but if the appropriate relay fails or the circuit breaker fails to trip, the next relay in the grading sequence will complete its operation and trip the associated circuit breaker, thereby interrupting the fault circuit one section further back.

过流保护或距离保护可作为前一种方案的例子，通常采用分时限区别来隔离故障段，如果相应的继电器拒动或断路器拒跳，按时限下一个继电器动作跳开有关的断路器，这样就断开了故障回路的下一段。采用这种方法就获得了完整的后备保护。
