线路过电压保护器使用环境 Use environment of line overvoltage protector 环境温度:-40~50度; 海拔高度:2000m及以下(建议:高于2000m选用专用高原型产品); 电源频率:58-62Hz,(60Hz系统)、48-52hz(50Hz系统); 安装场所的空气中不应含化学腐蚀气体、蒸汽、爆炸性尘埃; 长期使用于以后下异常条件,保护器需特别订制,应该提前说明: 1)温度或海拔超标; 2)使用环境存在严惩潮气或腐蚀气本杂质(水上、盐场、化工厂等); 3)强紫外线辐射(高原、强日照干旱地区等); 4)特重污秽地区(矿山工作面、建筑工地工作面等) Ambient temperature: -40 to 50 degrees; altitude: 2000m and below (recommended: higher than 2000m for special plateau type products); power frequency: 58-62Hz, (60Hz system), 48-52hz (50Hz system); the air in the installation site should not contain chemical corrosion gas, steam, explosive dust; long term used in later abnormal conditions. The protector needs to be specially made and should be explained in advance: 1) the temperature or elevation exceeding the standard; 2) the environment exists to severely punish the tidal gas or corrode the gas (water, salt, chemical plant, etc.); 3) strong ultraviolet radiation (plateau, strong sunshine arid areas, etc.); 4) special heavy foul area (mining face, construction worker) Ground working face, etc. |
