上海昌开电器有限公司一、用途 交流系统用瓷（复合）外套无间隙金属氧化物避雷器是用来保护相应等级的交流电气设备免受雷电过电压和操作过电压损害的保护电器。 产品执行标准：GB11032/IEC60099-4 （交流系统用无间隙金属氧化物避雷器）二、使用条件1.适用户内、户外2.环境温度（-40+48）3.太阳光最大辐射强度1.1kW/4.海拔高度不超过2000m5.电源频率（48-62）Hz6.地震强度8度及以下地区7.最大风速不超过35m/s8.长期施加在避雷器端子间的工频电压应不超过避雷器的持续运行电压三、结构和特性 该类避雷器由非线性金属氧化物电阻片叠加组装，密封于绝缘瓷外套内，无任何放电间隙。在正常运行电压下，避雷器呈高阻绝缘状态；当受到过电压冲击时，避雷器呈低阻状态，迅速泄放冲击电流入地，使与其并联的电气设备上的电压限制在规定值，以保证电气设备的安全运行。该避雷器设有压力释放装置，当其在超负载动作或发生意外损坏时，内部压力剧增，使其压力释放装置动作，排除气体，避免瓷外套爆炸。本避雷器具有陡波响应特性好，冲击电流耐受能力大，残压低、动作可靠、耐污秽能力强、维护简便等特点。四、型号说明1.1、型号含义
