LEMLA1500—T/SP29和LEM LV200—AW/2/SP28分别是8K型电力机车上所用的电流和电压传感器,由法国阿尔斯通公司委托日内瓦LEM公司生产。这种传感器具有以下特点: 1)能测量任何形式的电流电压(如直流、交流、脉冲形的电流或电压); 2)初级电路和次级电路间为完全绝缘; 3)精度优于1％; 4)线性度优于0.1％; 5)响应速度快,继电时间小于1μs; 6)频带很宽,为0～100KHz; 7)测量范围和过载能力大; 8)体积小,重量轻(如LAl500—T/SP29与国产测量同样电流大小的直流电流传感器比较,重量轻一半,约为7kg)
LEMLA1500-T / SP29 and LEM LV200-AW / 2 / SP28 are current and voltage sensors used on 8K electric locomotives, respectively, commissioned by the French Alstom company Geneva LEM company. The sensor has the following features: 1) It can measure any type of current and voltage (such as DC, AC, pulse current or voltage); 2) Complete insulation between primary circuit and secondary circuit; 3) Accuracy better than 1% ; 4) The linearity is better than 0.1%; 5) The response speed is fast, the relay time is less than 1μs; 6) The wide frequency band is 0 ~ 100KHz; 7) The measuring range and overload capacity are big; Such as LAl500-T / SP29 with the same current measurement of domestic DC current sensor size, light weight, about 7kg)
