LMZC高精度電流互感器 LMZC high-precision current transformer 概述 General description LMZC高精度電流互感器適用于交流電力系統35kV和10kV以下供用電設備的電流、電能測量和保護。該電流互感器具有體積小、重量輕、便于安裝等特點,已在SafeRing/SafePlus、RM6/SM6、SVS、GA/GE、FB、SS、FTR等系列緊湊型全絕緣環網開關柜中廣泛應用。 LMZC high precision current transformer is suitable for current measurement and protection of distribution equipments in 35kV and 10kV AC power system. It is widely used in compact fully insulated ring net switch cabinets such as SafeRing/SafePlus, RM6/SM6, SVS, GA/GE, FB, SS and so on because of its small volume, light weight, and convenient installment. It is very convenient that the transformer can be directly installed at connected output and input cables. 該型電流互感器選用新型導磁材料作為測量繞組的鐵芯,其高磁導率、較低的飽和磁感應強度和優良的穩定性,保證了較高的測量準確度和較低的儀表保安系數,優質進口硅鋼片經先進工藝加工后作為保護繞組的鐵芯,保證了較高的準確限值系數。 New magnetic material is taken to be the core of the current transformer, which has high magnetic permeability, low saturation induction density and good stability. Therefore, the measuring accuracy is higher and the instrument security factor is lower. Since the high quality silicon steel sheet metal processed by advanced technology is taken to be the core of the protection windings, the accuracy limit factor will be higher. 環型鐵芯和二次繞組采用優質環氧樹脂真空澆注在可阻燃的塑料殼體內,防潮濕,性能穩定,無需維護。該型電流互感器體積小、重量輕,占用空間小,固定在環網開關柜的電纜室內,安裝時只需將電纜從內孔穿過,簡便快捷,和諧美觀。 The circular ring core and secondary windings are vacuum poured by high quality epoxies resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance. The cable can cross the current transformer t
