产品介绍
跌落式(可投式、可卸式)避雷器是将配电型氧化锌避雷器改装后巧妙地安装在跌落熔断器的跌落式机构上,达到在不断电的情况下,可以借助绝缘拉闸操纵杆方便地对避雷器进行检测,维修与更换,不但保证了线路的畅通,而且大大地减少了电力维护人员的工作强度和时间,特别适合于不宜停电的场所如邮电通讯、机场车站、医院、繁华商业区等。产品其它性能同配电型避雷器。
??? 第二代跌落式避雷器增加了脱离器,在避雷器出现异常发生故障时,利用工频短路电流让脱离器动作,使脱离器接地端自动脱开,避雷器元件翻落,退出运行防止事故进一步扩大,并易于维护人员及时发现进行维护和更换。其翻落原理类似熔断器熔丝熔断引起熔管翻落。
??? 我公司采用了目前国际最先进的RW12型跌落机构,接触可靠、分合灵活,并采用复合支柱和不锈钢盖的先进配件,具有防污防腐好等优点。脱离器有热熔式和热爆式两种,热熔式脱离器简单经济;热爆式脱离器具有动作速度快,动作电流范围广,又能耐受规定电流冲击和动作负载的优点。
??? 产品性能满足国家标准GB11032-2000(eqvIEC60099-4:1991)《交流无间隙金属氧化物避雷器),JB/T8952-2005《交流系统用复合外套无间隙金属氧化特避雷器》,GB311.1-1997《高压输变电设备的绝缘配合》。
