Discussion on the effect of sputum on the development and change of seasonal febrile disease and its treantment 论痰对温病发展传变的影响及其治疗
But because ct at the time of the saturations have the complicated in wave form electric current , how correct to judge the saturations constantly , determine ct their the linear to spread becoming area protection of difficult point it be 但是由于ct饱和时电流波形复杂,如何正确判断ct饱和时刻、测定其线性传变区一直是此类保护的难点所在。
The mutual inductor of electric current and voltage mutual inductor play an important role in relay protection . prevent from ct differential to protect and miss movement an important subject that the generatrix is protected on the saturation , put forward two electric current pass zero hour linear to spread person who become put into differential to protect in ct in recent years , avoid ct saturation district , can judge the bus bar trouble correctly 但是在母线区外发生短路故障(特别是故障电流含有大量非周期分量)时, ct会出现饱和现象, ct饱和后,不能正确地传变一次侧电流,从而使二次电流发生严重畸变,产生很大的差电流,这样就容易引起误动作。防止ct饱和时差动保护误动作一直是母线保护的一个重要课题,近年来提出的在ct二次电流过零时的线性传变区投入差动保护,避开ct饱和区,能对母线故障做出正确判断。
