| 摘 要： | 当线路发生短路故障时,重要特征之一是线路的电流急剧增大,当电流流过某一预定值时,反应于电流升高而动作的保护装置叫过流保护。而三段式电流保护具有作为主保护和后备保护的全部功能,在实际中得到广泛应用。 |
| 关 键 词： | 三段式电流保护 瞬时 时限 定时限 |

| Abstract: | When the line short-circuit fault occurs,an important feature of the line current increases rapidly.When current flows through a predetermined value,reflected in the current rise and the action is called overcurrent protection device. |
| Keywords: | three-current protection instantaneous time definite time |
