Description by Manufacturer

电力测功机

电力测功机测试系统采用交流变频反馈加载，负载能量通过交流负载发电机反馈给电网;扭矩和转速由扭矩传感器直接测量;电的综合测量仪器，检测电流、电压、频率、功率因数等;计算机自动检测、显示并完成数据处理、报表和各种曲线。一种使用电机测量各种动力机械轴上的扭矩输出并结合转速以确定功率的装置。

由于被测动力机械可能具有不同的转速，因此用作电力测功机的电机必须是能够平稳调节速度的电机。电力测功机分为直流电力测功机和交流电力测功机，最常用的是交流电力测功机。

测试项目：根据客户对不测试的要求，本测试系统可以对电机进行以下测试

1）空载试验：按GB/T1032，在额定正弦波下进行试验，调整试验电压，计算机采集数据，拟合曲线，确定风摩擦力和铁耗

2）堵转试验：按GB/T1032，在额定正弦波下进行试验，调整试验电压，计算机采集数据，拟合曲线，确定堵转转子电流和堵转转矩。

3）负载试验：按GB/T1032，在额定正弦波下进行试验，调整试验的负载，计算机采集数据，拟合曲线，确定电流、电压、功率、效率、频率、滑差率等

4）温升试验：按GB/T1032，在额定正弦波下进行试验，调整负载进行试验，用用户原桥手动测量电枢电阻，计算机采集数据，计算机拟合温升曲线。

5）M-S曲线：（最大扭矩和最小扭矩的测量）：采用扭矩测量仪方法。如果电源、负载等的容量允许，可以通过绘制 M-S 曲线来完成。

注：对于大型电机在启动过程中使用其高速采集和绘制M-S曲线，由于启动时转速变化率较大，冲击转矩和冲击电流也相应较大，因此应特别注意防止对转矩传感器、电网等的冲击。

要完成失速转子和 M-S 曲线测试，必须满足以下测试条件：

a）具有足够大的供电能力：4-7倍于电机额定电流。

b）要求试验载荷能够在高低速范围内稳定加载

c）考虑到高转矩工况的试验，一般要求负载电机的最大转矩为被测电机额定功率的3倍，因此负载电机的额定功率也要求为被测电机额定功率的3倍，扭矩传感器量程的选择也应注意扭矩传感器的选择大于被测电机额定转矩的3倍。
