The product safely protects transform equipment and has the features of simple structure, convenient installation and maintenance and long use life.

一、特点 Features 本公司生产的氧化锌避雷器具有良好的伏安特性和优异的保护性能及冲击响应特性、高耐受多重雷及操作过电压能力、良好的耐污性能等优点，并且结构简单，安装维护方便，使用周期长，能对输变电设备提供最佳保护。

The influence of the line arrester on the lightning withstand level of 35kV transmission lines was simulated and calculated by electromagnetic transient software ATP-EMTP. The results show that the joining of line arrester can obviously improve the lightning withstand level of 35kV transmission lines, and is especially effective when the lightning directly strikes the conductor.

计算结果表明，在"易击段"架设线路避雷器后，可明显提高35kV输电线路的耐雷水平，尤其雷直击导线时，线路避雷器的作用效果更加明显；雷击杆塔塔顶时，杆塔接地电阻是影响35kV输电线路耐雷水平的重要因素。

The results indicate:1 There are limitations to protect 110kV Kang-Ping transmission line and 220kV Da-An transmission line lightning, and the line-surge arrester can improve the lightning-proof property of transmission line on mountainous area and enhance the lightning-withstand level.2 Tower grounding resistance, distance between towers, etc can affect the function of line-surge arrester.

110kV康平线和220kV大安线已有的防雷措施不够理想，而加装了线路型避雷器后能明显改善山区输电线路的防雷性能，提高输电线路耐雷水平。2）输电线路的接地电阻，线路档距等因素对线路型避雷器的应用有影响。

The pleunm anti-static insulated material housing prevents short circuit led by the contact of welding spot and the metal channel of word sign. At the same time, the circuit uses particular constant current design and lightning arrester. Silicon rubber leads between modules of anti-aging and anti-cracking guarantee the long-term work in bad environment of open area while the low resistance of lead reduces the affection to the emitting brightness of LED by voltage drop.

其外壳采用阻燃防静电绝缘材料，可防止 PCB焊点与金属字槽壳的接触而产生短路，同时电路采用独特恒流电路设计及雷电吸收装置，模组间连接线采用软硅橡胶导线，在恶劣的户外恶劣环境下长时间使用，导线不会老化脆裂，同时导线内阻比较小，降低压降对LED发光亮度的影响。
