型号及其含义
结构特点
该系列产品箱体结构分为前后两部分。前面为高低压操作间隔。高压间隔内包括高压端子、负荷开关、无载调压分接开关、插入式熔断器、压力释入阀、油温计、油位计、放油阀。低压间隔内包括低压端子。后部为注油箱体及散热片,变压器绕组和铁芯、高压负荷开关及保护用熔断器都在储油箱中。
1、体积小,结构紧凑,仅为国内同容量箱变的1/3左右;
2、全密封、全绝缘,无需绝缘距离,可靠保证人身安全;
3、既可用于环网,又可用于终端,转换十分方便,提高了供电的可靠性;
4、损耗小,低于国内s9型变压器损耗;
5、电缆接头可操作200a负荷电流,在紧急情况下可作为负荷开关操作,并具有隔离开关的特点;
6、采用双熔丝保护,降低了运行成本。插入式熔断器熔丝为双敏熔丝(温度、电流);
7、采用了△/y接法及三相五柱式结构,优点是电压质量高、中性点不漂移、箱体不发热、噪音低、防雷性好。
