摘要:
主要通过EMPT电磁暂态分析软件对10 kV串联间隙金属氧化物避雷器在配电网系统中安装使用时进行仿真分析,首先进行PS15绝缘子及10 kV环电极避雷器及穿刺避雷器产品的U50%放电电压试验,再仿真分析在不同接地条件下只安装单相产品对同级其它相绝缘子的影响及只安装一级对相邻级绝缘子的影响,分析得出无论是直接接地还是单独接地,当雷电流超过40 kA 后均会造成相邻相或相邻级的绝缘子闪络,建议全线安装或在雷击严重区段及易击点全线安装10 kV串联间隙金属氧化物避雷器,不需单独设置接地,条件允许可在末端设置接地。
Abstract:
EMPT electromagnetic transient analysis software is adopted to simulate the installation and operation of 10 kV series gap metal oxide arrester in distribution network. Firstly, the U50% discharge voltage test was carried out on PS15 insulator and 10 kV ring electrode and piercing electrode arrester. Then, the influence of installing single-phase products only on other phase insulators of the same class and the influence of installing only one stage on adjacent insulators under different grounding conditions are simulated and analyzed. It is concluded that when the lightning current exceeds 40 kA, the insulator flashover of adjacent phase or adjacent stage will occur, whether directly grounded or individually grounded. It is suggested to install 10 kV series gap metal oxide arrester on the whole line or in the severely lightning stricken section and vulnerable point. It is not necessary to install grounding separately. If the condition permits, grounding can be set at the end of the line.
