MZC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於交流電力系統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、便於安裝等特點，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櫃中廣氾應用。
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，保証了較高的測量準確度和較低的儀表保安係數，優質進口硅鋼片經先進工藝加工后作為保護繞組的鐵芯，保証了較高的準確限值係數。
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採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，固定在環網開關櫃的電纜室內，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 through its internal poles quickly and uniformly.
依據電流變比、準確級和額定負載的不同，該系列電流互感器分為以下幾種類型，具體參數詳見各型號對應的參數表。
The current transformers can be divided several kinds according to the various current ratio, accuracy and rated loads. The specific parameters are showed in the corresponding parameter tables of every type.
