HXGN17-12Z箱型固定式金屬封閉開關設備（真空環網柜）
HXGN17-12Z Chest-type, Fixed Metal-enclosed Switchgear (Vacuum Circulating Network Switchgear)
性能與用途
HXGN17-12柜內所裝新型高壓真空負荷開關-熔斷器組合電器ZFN-12，具有開斷能力大，安全可靠，電壽命長，可頻繁操作，基本不需維護的特點。操動機構采用電動彈簧機構或彈簧儲能式手動機構，不因所施操作力的大小影響負荷開關分合閘速度，操作簡便，不會發生火災爆炸危險，體積小，重量輕，占地面積小，利于減少基建投資。
適用于交流50Hz，12 kV的電力網絡中，作為環網供電和終端供電設備使用。
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.
