概述 /Summary
LMK1、2-0.66(BH、MSQ) 系列型电流互感器，供额定频率为 50Hz，额定电压为 0.66kV 及以下的电力系统中作电流、电能测量和继电保护之用。
◆ 品种规格齐全，适用范围广，适用于一次电流为 5A 至 5000A,1A 至 4000A 的全部规格 ( 包括非标规格 )。二次电流有 5A 或 1A 两种，设计不同窗口种
类可与任何汇流排及电缆对应使用；
◆ 外形设计美观、合理；
◆ 指标先进、国内领先，结构性能优良；
◆ 与国类产品相比，体积小、重量轻、容量大、精度高，符合电控设计紧凑化趋向的要求；
◆ 安全、阻燃、表面无一处带电，壳体由进口阻燃材料高压注塑成型，强度高且不燃烧；
◆ 坚固、耐用，整个产品为全封闭型，有耐温、防潮、防振、防污、防盐雾、防窃电等特点。
Series LMK1, 2-0.66(BH,MSQ) current transformer is mainly used for power system with rated frequency 50Hz and rated voltage under 0.66 kV to measure electric
energy, current and protect relay.
◆ With full complete of specification and wide range of application, suitable for any primary current range from 5 A to 5000A or from 1A to 4000A (including non-
standard specification), the secondary current has two types: 5 A and 1 A, the different window types can match with different bus-bars and cables;
◆ With nice appearance and reasonable design;
◆ With advanced technology and excellent performance;
◆ Compared to same line of products, this product is more compact, less weight, larger capacity, higher accuracy and more compliance with the standard of electric-
control design;
◆ With features such as safety, flame retardant, without static electricity in the surface, the case is made of imported flame retardant material by high-pressure casting,
so it has feature of high strength and resisting flame;
◆ With features of firmness, durability, full-seal, high temperature resistant, moisture proof, shock proof, anti-salt spray and prevent from electric-theft.

使用范围 /Application Scope

◆ 工作电压：<0.66kV；
◆ 额定频率：50-60Hz；
◆ 海拔高度不超过：1000m；
◆ 周围介质温度为：-5℃ ~+40℃； J
◆ 空气相对温度不超过：85%；
◆ 用于没有雨雪直接侵袭，无严重污染，无爆炸无剧烈震动、无腐蚀金属和破坏绝缘的尘埃或蒸汽的场所。
◆ working voltage: < 0.66kV;
◆ rated frequency: 50-60Hz;
◆ altitude: < 1000m;
◆ ambient temperature: -5℃ ~+40℃ ;
◆ RH: ≤ 85%;
◆ environment without rain or snow, no heavy pollutant, no explosion or shock, no corrosive metal or dust or steam.

使用方法 /Using Method
◆ 根据一次电流及母线截面等参数选取对应的规格。一次导线 ( 一次线圈 ) 穿越 CT 窗孔，卸下 CT 顶部接线罩壳，支掉引线垫片，二次线引出后罩壳复位，
计量电能用的可利用固定螺丝和罩壳上小孔加封铅印，以防窃电；
◆ 产品极性表示，P1 表示一次线圈的极性端，S1 表示 P1 的同名端，S2 表示 P2 的同名端。

◆ Select the suitable specification according to primary current and section of bus. The primary windings go through the window-hole of CT, dismantle the cover on the
top of CT and remove shim, the cover will return to its original position after the secondary windings lead out, use screw to fix it and seal with lead inside the hole of case
to prevent from electric-theft;
◆ Polarity: P1 indicates the polarity of primary winding, S1indicates the same polarity of PI, S2 indicates the same polarity of P2.
