| 摘 要： | 配电网架空线路雷击跳闸率高,绝缘导线还存在雷击断线问题。针对此问题,模拟试验和计算研究了配电网冲击绝缘耐受水平,得出采用2种不同绝缘水平的绝缘横担时的雷击跳闸率;针对目前采用氧化锌避雷器铺设地网施工难度大及接地引下线易被盗问题,研究开发出10 kV线路雷击闪络保护器,试验研究了其动作特性。根据试验和仿真计算结果,提出的配电网线路防雷措施,可以防止雷击断线并降低线路雷击跳闸率80%以上。 |
| 关 键 词： | 配电线路 雷击断线 雷击跳闸率 绝缘横担 闪络保护器 防护措施 |

| Abstract: | The lightning trip-out rate of the transmission lines of distribution network is high and insulated wires have the problem of lightning-caused breakage.So the solution of reducing the lightning trip-out rate and preventing the lightning-caused breakage should be found out simultaneously.By researching the impulse withstand level of distribution network through simulated tests and calculations,two different lightning trip-out rates of transmission lines adopting insulator crossarms with different insulation ... |
| Keywords: | distribution lines lightning-caused breakage lightning outage rate insulator crossarm lightning-flashover protector protection measures |
