HXGN17-12Z箱型固定式金属封闭开关设备（真空环网柜）
HXGN17-12Z Chest-type, Fixed Metal-enclosed Switchgear (Vacuum Circulating Network Switchgear)
性能与用途
HXGN17-12柜内所装新型高压真空负荷开关-熔断器组合电器ZFN-12，具有开断能力大，安全可靠，电寿命长，可频繁操作，基本不需维护的特点。操动机构采用电动弹簧机构或弹簧储能式手动机构，不因所施操作力的大小影响负荷开关分合闸速度，操作简便，不会发生火灾爆炸危险，体积小，重量轻，占地面积小，利于减少基建投资。
适用于交流50Hz，12 kV的电力网络中，作为环网供电和终端供电设备使用。
Functions and Applications
HXGN17-12Z switchgear is equipped with ZFN-12 electric appliance combined of a new type high voltage
vacuum load switch and a fusible cutout. Its characteristics include : strong breaking capacity, safe and reliable
performance, long service life, frequent operation allowance and basically no main tenance needed. Because
of its electrical spring operation mechanism or spring-energy-storage type manual operation mechanism, the
disconnecting and closing speed will not be affected by the operating force applied. It is easy to operate and
there is no explosion risks caused by fire. Furthermore, its small volume and light weight characteristics are definitely advantages in the reduction of construction cost.
It is used in electric network (AC, 50Hz，12 kV) to be circulating network and terminal power supply.
