FN5-12系列戶內高壓負荷開關及熔斷器組合電器

概述

Summary

FN5-12R(L)型戶內交流高壓負荷開關-熔斷器組合電器是我廠吸收消化國外先進技術，結合我國的供電要求，自行設計研制而成的。該產品經全面型式實驗和長期的試運行考核、性能達到IEC420《交流高壓負荷開關-熔斷器組合電器》(1990版)和GB3804 《3-63KV交流高壓負荷開關》標準要求，與國外同類產品比較，技術參數已達到同類產品水平，具有體積小、重量輕，可用于環網柜和箱式變電站，廣泛應用于12KV線路的電能分配，并有效地避免了設備的缺相運行。

該產品的研制成功填補了國內空白，可實現開關、隔離和接地三工位。

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.
