避雷器安装方式一 ( 第一代避雷器安装方式 )：
Installation of a lightning arrester (first generation arrester installation):

/ 电力设备

优点：安装方便
缺点：避雷器出现故陣不易发现，检修更换需要断电作业，线路维护工作量大，工作效率低。 合成绝缘子 Composite insulator / electrical equipment
避雷器安装方式二 ( 第二代避雷器安装方式 )：
优点：安装方便，故陣点易于发现
缺点：虽然故陣点易于发现，由于避雷器在低压端退出电网运行，因此检修更换还需要断电作业，线路雏护还是不方便
避雷器安装方式三 ( 第三代避雷器安装方式 )：
优点：安装方便，故陣点易于发现，由于避雷器在高压端退出电网运行，因此检修更换可带电作业，节省了大量的人力，极大的提高了工作效率，目前
YH5WS-17/50DL 是比较实用的安装方式。

Advantages: easy to install
Disadvantages: arrester array so difficult to find, repair and replacement work needs power line maintenance workload, low efficiency.
Arrester mounting di- (second generation arrester installation):
Advantages: easy to install, it is easy to find lattice points
Cons: While it is easy to find lattice points due to the low pressure side exit arrester grid operation, repair and replacement needs and therefore off the job, the line is not
convenient or child care
Arrester installation of three (the third generation arrester installation):
Advantages: easy to install, it is easy to find lattice points due to the high voltage side arrester exit grid operation, repair and replacement can therefore live working, save a lot
of manpower, greatly improves the efficiency of the current YH5WS-17 / 50DL is more practical installation.

工作原理 /working principle

跌落式带脱离装置无间隙金属氧化物避雷器 (YH5WS-17/50DL-TB) 是将带脱离金属氧化物避雷器的先进理念和跌落式熔断器的原理相结合，除具备金属氧
化物避雷器的过电压保护功能外，又可在发生异常故障时，工频短路电流使脱离器动作，其接地端自动脱开，避雷器翻落退出电网运行，检修维护方便的更
换，提高了电网的供电质量
Drop-out principle means gapless metal oxide surge arresters (YH5WS-17 / 50DL-TB) is a band from the band from MOA advanced concepts and drop-out fuse combined,
with the exception of over-voltage metal oxide surge arresters protection function, but also in the array so that when an exception occurs, the power frequency short-circuit
current from the device to make operation of its ground terminal is automatically released arrester exit turn over power grid operation, repair and maintenance easily replace
and improve the quality of power supply
