| Abstract: | This paper presented the meaning of adding time-limit quick break protection at the branches of the high voltage house substation in detail,and also deduced the boundary conditions for its application.It also indicates that time-limit quick break protection could be influenced by the new type load at medium and low voltage bus,and then compares the time-limit quick break protection with the electric arc protection.The comparison results show that the time-limit quick break protection is an excellent protection scheme from the point of view of economy and practical use. |
