产品介绍

产品简介:

   KYN28-24铠装中置式金属封闭开关设备是我公司在吸收国外先进制造技术的基础上自行设计开发的新型产品。其产品具有以下明显优点:1.产品的外壳完全是由敷铝锌钢板经CNC机床加工多重折弯成型后用螺栓组装而成,具有很高的机械强度,有效地保护了产品的整齐和美观,柜门采用喷塑涂覆,具有较强的抗冲击和耐腐蚀能力。产品外壳具有IP4X级的防护等级。2.本产品的主开关可配置我公司自行研制开发的CRS1-24型真空断路器。3.无论是选用何种断路器,期电气间隙相间≥180mm。相对地≥200mm,绝缘件沿面爬距≥480mm,当不能满足时采用复合绝缘。其断路器具有长寿命、高可靠性、少维护、体积小的独特优点。

适用范围:

KYN28-24铠装中置式金属封闭开关设备适用于3.6~24KV三相交流50或6Hz电网,作为接受和分配电能,并对电路实行控制、监测和保护之用。可用于单母线、单母线分段系统。开关设备符IEC62271《额定电压1KV以上52KV及以下交流金属封闭开关设备和控制设备》、IEC60694《高压开关和控制设备标准的公用技术要求》,我国的GB3906《3.6KV~40.5KV交流金属封闭开关设备和控制设备》及DL/T404《3,6~40.5KV交流金属封闭开关设备和控制设备》。并具有晚上、可靠的防误操作功能。

正常使用条件:

1.周围空气温度:上限40℃,下限-15℃;

2.相对温度:日平均值不大于95%,月平均值不大于90%;

3.海拔:不超过1000m;

4.地震烈度不超过8度;

5.无火灾、爆炸危险、严重污秽、化学腐蚀及剧烈震动的场合。

当使用条件超出上述范围,应由用户与制造厂商协商确定允许范围及技术措施。
