| 间隙避雷器的工作原理：基于电弧放电技术，当电极间的电压达到一定程度时，击穿空气电弧在电极上进行放电。 The working principle of gap arrester: Based on arc discharge technology, when the voltage between electrodes reaches a certain degree, the air arc breakdown is discharged on the electrode. 优点：放电能力强，通流量大（可以达到100KA）漏电流小 Advantages: strong discharge capacity, large flow rate (up to 100KA), small leakage current. 热稳定性好 Good thermal stability 缺点：残压高，反映时间慢，存在续流 Disadvantages: high residual pressure, slow response time and persistent flow. 工艺特点：由于金属电极在放电时承受较大电流，所以容易造成金属的升华，使放电腔内形成金属镀膜影响避雷器的启动和正常使用。放电电极的生产主要还是集中在国外一些避雷器生产企业，，电极的主要成分是钨金属的合金。 Technological characteristics: metal electrode withstands a large current during discharge, so it is easy to sublimate the metal, so the formation of metal coating in the discharge chamber affects the start-up and normal use of the arrester. The production of discharge electrode is mainly concentrated in some foreign lightning arrester manufacturers, the main component of the electrode is tungsten alloy. 工程应用：该种结构的避雷器主要应用在电源系统做B级避雷器使用。但由于避雷器自身的原因容易引起火灾，避雷器动作后（飞出）脱离配电盘等事故。根据型号的不同适合与各种配电制式。 Engineering application: the lightning arrester of this kind of structure is mainly used in power supply system to make use of B class surge arrester. However, the lightning arrester itself is easy to cause fire, lightning arrester action (fly out) from the distribution panel and other accidents. According to the different models, it is suitable for various distribution systems. 工程安装时一定要考虑安装距离，避免引起不必要的损失和事故。 Installation distance must be considered in engineering installation to avoid unnecessary losses and accidents. |
