FN5高压负荷开关 FN5-12RL型户内交流高压负荷开关
FN5-12R(L)型户内交流高压负荷开关-熔断器组合电器是我厂吸收消化国外先进技术，结合我国的供电要求，自行设计研制而成的。该产品经全面型式实验和长期的试运行考核、性能达到IEC420《交流高压负荷开关-熔断器组合电器》(1990版)和GB3804 《3-63KV交流高压负荷开关》标准要求，与国外同类产品比较，技术参数已达到同类产品水平，具有体积小、重量轻，可用于环网柜和箱式变电站，广泛应用于12KV线路的电能分配，并有效地避免了设备的缺相运行。
该产品的研制成功填补了国内空白，可实现开关、隔离和接地三工位。
It is designed and developed by our own company by bringing in international advanced technology, considering our own country’s specificpower supply. It performances meet IEC420 《AC H.V Load Switch with Fuse》(1990 Edition) and GB3804 《3-63KV AC H.V.Load Switch》after strict test and long-time operating. compared to product of the kind in the foreign country , its technical parameter has reached the international level with the features of small volume and light weight. Can be used in package substation and ring network cebin . It is used widely in 12KV distribution network to protect the equipment againet working without phase.
The sucess of the product fills the domestic gap ,with functions of switch、isolating and earthing. |
