Jeremiah 50-51 NIV - A Message About Babylon - Bible Gateway
50 This is the word the Lord spoke through Jeremiah the prophet concerning Babylon and the land of the Babylonians[a]: Marduk filled with terror. and her idols filled with terror.’. and lay waste her land. both people and animals will flee away. will go in tears to seek the Lord their God. and turn their faces toward it. that will not be forgotten.
热过负荷保护（ANSI 49）与相过流保护（ANSI 50/51）的区别是 …
热过负荷保护可防止电气设备运行于超过设计允许的最大温升。 长期过负荷运行会引起过热，从而导致绝缘过早老化，甚至绝缘破坏引起短路等严重故障。 热过负荷保护的原理就是考虑各种影响热态（温升）计算的因素，利用热态模型计算公式计算热态，将计算的实时热态值与设定的报警值和跳闸值比较从而发出相应信号。 热过负荷保护与相过流保护的主要区别是： 1. 热过负荷保护中的电流值都是 RMS 值考虑了谐波电流的温升影响，例如 P3U30 到 15 次谐波， sepam M41 到 …
Instantaneous and Time-overcurrent (50/51) Protection
In protective relay-based systems, the instantaneous overcurrent protection function is designated by the ANSI/IEEE number code 50. Time overcurrent protection is where a protective relay initiates a breaker trip based on the combination of overcurrent magnitude and overcurrent duration, the relay tripping sooner with greater current magnitude.
