| HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器 联系人：*总 联系电话： 联系手机： 用途及标准 本产品使用于交流220kV及以下发电、输电、变电、配电系统，用于将雷电和系统内部操作过压电的幅值限制到规定的水平，是整个系统*缘配合的基础设备。同时，本产品不能用于限制谐振过电压，系统消谐需要采用其它方式。 本产品型号按*/T8459-1996《避雷器产品型号编制方法》规定进行编制，无间隙产品执行GB11032-2000《交流无间隙金属氧化物避雷器》标准；有间隙产品执行*/T9672-2005《有串联间隙金属氧化物避雷器》标准。对以上标准中未明确定义的重要参数及配置方式，按DL/T620-1997《交流电气装置的过电压保护和*缘配合》的要求修正执行。 使用条件： 常规产品正常使用条件如下： 环境温度：不高于+40℃，不低于-40℃； 海拔高度：不*过2000m； 电源频率：50±2Hz；60±2Hz； 地震强度：7度以下； *大风速：35m/s； 免清扫条件：中等污秽及以下地区； 对无间隙产品，长期施加的工频电压不得*过避雷器持续运行电压； 对有间隙产品，安装点短时工频电压升高不得*过避雷器额定电压。 长期使用于以下异常条件，避雷器需*制作，定货时应说明： 温度或海拔*标（高原、热带、寒带、全封闭柜用、靠近电炉等） 使用环境存在严重潮气或腐蚀性气体杂质（水上、盐场、化工厂等）； 强紫外线辐射（高原、强日照干旱地区等）； 特重污秽地区（矿山工作面、建筑工地工作面等）。 HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器、HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器、HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器、HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器、HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器、HY5WR-42/134电容避雷器HY5WR-51/134氧化锌避雷器 英语翻译： Use and the standard This product is used in ac 220 kV and below, substation, power generation, tran*ission and distribution system, used for lightning and system internal operating over-voltage electricity amplitude limit prescribed level, is the whole system of insulation coordination based equipment. At the same time, this product can not be used in limit over-voltage resonance, system harmonic need to adopt the other way away. This product model according to the */T8459-1996 "lightning arrester product model establishment method" regulation for establishment, no clearance product executive GB11032-2000 "exchange non-clearane metal oxide lightning arrester standard of"; Have clearance product executive */T9672-2005 "series have clearance metal oxide lightning arrester" standards. Not to the above standard definition of important parameters and configuration, press DL/T620-1997 "ac electric device overvoltage protection and insulation coordination requirements of the fixed execution. Conditions of use: Normal product normal use conditions as follows: Environmental temperature: no higher than + 40 ℃, no less than 40 ℃; Height: no more than 2000 m; Power frequency: 50 ± 2 Hz; 60 ± 2 Hz; The earthquake intensity: 7 degrees below; With maximum sustained winds of 35 m/s; Avoid cleaning the conditions: medium and the following areas unclean; To no clearance product, the industrial frequency voltage on long term shall not exceed lightning arrester continued operation voltage; To have clearance product, installed point power frequency voltage increase short-term shall not exceed lightning arrester rated voltage. Use for a long time in the following abnormal condition, lightning arrester need special production, when an order should inform: Temperature or exceed altitude (plateau, tropical, cold, fully enclosed with electric furnace, etc, near the ark) Use environment there is serious moisture or corrosive gas impurities (water, salt pan, chemical plants, etc.); Strong ultraviolet radiation (plateau, strong sunshine drought areas etc.); Heavyweight filthy area (mining face, construction site mining face, etc.). |
