概述 General description
OSMT-10系列开启式电流互感器适用于交流电力系统35kV和10kV以下供用电设备的电流测量和微机保护。该电流互感器具有体积小、重量轻、可开启、便于安装等特点，广泛用于紧凑型全绝缘环网开关柜中，安装时直接卡在连接好的进出线电缆上，简便快捷。已在ABB-SafeRing/SafePlus、施耐德RM6/SM6、伊顿SVS、德国GA/GE、法国FB、韩国SS等紧凑型全绝缘环网开关柜中广泛应用，亦用于组合式变电站和电缆分接箱中。
OSMT-10open-core current transformer is suitable for current measurement and microcomputer protection of distribution equipments in 10kV AC power system. It is widely used in not only compact fully insulated ring net switch cabinets such as ABB-SafeRing/SafePlus, RM6/SM6, SVS, GA/GE in Germany , FB in France and SS in Korea, but also combined substation and cable take-off boxes because of its small volume, light weight, open feasibility and convenient installment. It is very convenient that the transformer can be directly installed at connected output and input cables.
该型电流互感器选用了磁导率较高的优质进口硅钢片作为导磁材料，具有铁芯可分割、磁路损耗小的特点，其半圆环型铁芯和二次绕组采用优质环氧树脂真空浇注在可阻燃的塑料壳体内，防潮湿，性能稳定，无需维护。
High quality silicon steel sheet metal slug with very high magnetic permeability as transmit magnetism material are used in the measuring winging of OSMT-10 current transformer, so its core can be divieded and the magnetic circuit loss is little. The semicircular ring core and secondary windings are vacuum poured by high quality epoxide resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance.
安装时将两个半圆环卡在分相电缆上，用抱箍抱紧，与电缆于一体，和谐美观，35mm2-400mm2的10kV和35kV电缆均能适用，其抱箍有塑料抱箍和不锈钢抱箍两种。
The two half cirque of the current transformer encircle the split phase cable tightly and uniformly. It has two configuration formats of single ratio and double ratios and two
