| 摘 要： | 用西门子SIMARIS design设计软件通过模拟低压配电系统,计算配电网络参数,电子脱扣器与保护配合等途径分析一次低压短路事故。通过电子脱扣器整定及电弧限制短路电流的机理说明了主保护开关不起保护作用,造成配电柜严重烧毁的的原因。 |
| 关 键 词： | 配电系统 开关柜 脱扣器 |

| Abstract: | A short-circuit accident happened in a low voltage system was anaylized by using Siemens SIMARIS design software to simulate the low voltage distribution system,by calculating the coordination between the parameters of the distribution network and the electronic releaser.Based on the principle of the tuning of the electronic releaser and the arc limiting short-circuit current,the main reason that caused this accident was expounded,that is the main protection switch failed to work. |
| Keywords: | power distribution system switchgear releaser |
