概述 General
VS1系列真空断路器为额定电压12KV,三相交流50HZ的高压户外开关设备,是引进瑞士ABB公司技术结合国内行业发展状况,生产能力开发制造的产品.该产品总体结构为开头本体与操动机构一体安装的形式,采用复事绝缘结构,无污染、无爆炸危险，绝缘水平高。
本系列产品的操动机构为弹簧储能式，可采用交流操作，亦可用手动操作。
It is a kind of indoor hight-voltage switch equipment with 50HZ three-phase alternating current and 12KV rated voltage,with combined the tedhnique of the ABB corporation in Switzerland and domestic development state and maufacturing capability.The general framework of this prodret is taken the form combiined the front body and operatik system into one.
Because it adoped the composite insulated material,there is no pollution and explosion danger,the insulation level is high.
