接地保护装置
接地故障保护
Examples
- This ground fault protection function may be incorporated into a circuit breaker
这种功能可以一体化设计在断路器上。 - Ground fault protection
接地故障保护 - Ground fault protection this function trips ( opens ) a circuit breaker or sounds an alarm in the event that there is an electrical fault between one or more of the phase conductors and ground ( earth )
接地故障保护当一个或多个相导线与地之间出现电气故障时，接地故障保护通过跳脱断路器或报警来示警。 - So far , there has existed several kinds of theory of ground fault protection for field winding of generator . in these methods , pingpong bridge field ground protection is a simple and effective one
目前已有多种原理的发电机励磁回路接地保护，其中乒乓式励磁回路接地保护是一种简单有效的保护原理。 - To resolve the situation that the sensitivity of present ground fault protection schemes is low for the large - sized hydro - generators , a kind of protection scheme based on the fault component of third - harmonic voltage and two kinds of protection scheme based on the fault component of zero - sequence voltage at the terminals and neutral are developed , and they can obtain higher sensitivity and reliability and provide 100 % protection for the stator windings . the influence of noise on the stator ground fault protection based on the local modulus maximum of wavelet transform is analyzed
针对目前大型水轮发电机定子绕组单相接地保护灵敏度偏低的问题，通过分析单相接地故障后机端和中性点零序电压的变化特点，提出了一种基于机端和中性点三次谐波电压故障分量和两种基于机端和中性点零序电压故障分量的高灵敏度、高可靠性保护方案，并实现定子绕组的100 %保护。
