Tripping characteristics of circuit-breakers for line protection

在415V时，线路保护用断路器的脱扣特性，"I"脱扣器为固定式

Studies on several well-known blackouts reveal that the weakest parts of network, where branch MW flow limit violations most possibly occur, are the transmission lines suffering from flow transferring most greatly after the overloaded line tripping. Therefore, this paper attempts to speed up the solution by means of partial solutions instead of the whole network solution.

因此，本文试图通过对电力网络中薄弱环节安全性状况的分析获得整个系统的安全信息，即通过局部网络的分析替代全网潮流计算以达到降低工作量的目的。

His body is fragile, his feet are post-surgical and it seems as though his career might come to a sudden end by the possibility of his tripping over the time-line as he gallops up and down the court.

他的身体是脆弱的，他的脚在手术之后看起来就想他的职业生涯可能会会因为一个绊倒突然就结束，他在球场上的时间似乎已经快到尽头。

Mark ballasts "Class P" indicating approved integral ballast protection. This ballast protection is provided by a built-in self-resetting thermally actuated device that will remove the ballast from line when excessive ballast temperature is reached. See 1.07.F regarding nuisance tripping test data.

镇流器上有经过核准的&Class P&保护标志，镇流器保护是一套热激发自动启动装置，当镇流器的工作温度超过额定温度时可以将镇流器从供电回路中切断，请阅读1.07过载试验数据。

For example, a fault on the line terminals of breaker D. D tripping should be faster than B, however, the condition reverses and B should be faster than D.

考虑到瞬时和/或时间延迟继电器的应用在四个断路器上，很显然的这个类型继电器不能协调所有线路故障。

The study results had shown that the GPR and magnetic field of grounding system will produce detrimental effects on the breaker control system. Especially, for those poor insulation control lines, large GPR and longitudinal induction voltage during ground fault may lead to flash-over at control line terminals and thus inducing breaker mis-trip out. For the practical case in this thesis, to do well maintenance and to renew those old breakers and control lines with poor insulation situations are very important strategy for preventing breaker mis-tripping. Other protection measures from GPR and magnetic field induction interferences are important too. This study may provide useful information for planning the protection measures.

本研究结果显示变电所接地系统之GPR及其产生的磁场对断路器控制回路确有不利的影响，尤其当控制系统线路及端子若有绝缘不良，在接地故障发生的GPR及磁场纵向感应电压有可能造成闪络而引发断路器跳脱，对於本研究所探讨的案例而言，经由良好的维护或更新那些绝缘情况不良的老旧断路器及其控制线路，对於本研究所探讨的案例相当重要，而做好GPR及磁场感应干扰的防护措施亦相当重要，本研究分析结果可供规则防护措施之参考。
