文档介绍：低压电机使用维护说明书 1 电机使用说明书 Operating Manual 概述本说明书适用于我公司生产的YX3、YET、Y2、YVP、YD 系列低压三相异步电动机及其派生系列产品 Overview The manual serves YX3、YET、Y2、YVP、YD Series low voltage asynchro nous motors and it's derivative products as well. 开始使用 Putting into use (starting) 收货检查 Reception check 收到电机后立即检查是否有损坏,如发现请立即拨打电话:0086-21-6463-1777,或发传真至0086-21-6463-7180,检查铭牌数据特别是额定电压、接线方式(星形或三角形) 是否与合同订货要求相符,用手转动电机轴检查轴转动是否灵活。 Immediately check the motor for external damage upon receipt a nd if found, please inform us by telephone or fax without delay (Tel:0086-21 -6463-1777, Fax:0086-21-6463-7180). Check all rating plate data, especially voltage and winding connection (star or delta). Turn shaft by hand to check for free rotation. 绝缘电阻检查 Insulation resist ance check 在电机调试前或怀疑线圈受潮时要测量电机的绝缘电阻, 在25℃时的绝缘电阻值应超过以下表达式的值,表达式中: Measure the motor's insulation resistance missioning or when winding dampness is suspected. insulation Resistance, measured at 25°C, shall exceed the following reference value, . where: R:单位兆欧(用500V绝缘电阻表测量) U表示电压,单位V P表示功率,单位kW R: MΩ( measured with 500 V dc Megger ) U = voltage, Volts; P = output power, kW. 警告: 测量完绝缘电阻后应立即将测量线从电机上断开,以免线圈再次受到高电压冲击。环境温度每升高20℃,绝缘电阻将降低一半,如果绝缘电阻值达不到计算值,表明线圈已经 100 P 1000+ R= U 低压电机使用维护说明书 2 受潮需进行烘干处理。先在90℃温度下烘12-16小时再在105℃下烘6-8小时。 WARNING Windings should be discharged immediately after measurement to avoid risk for electric shock. Insulation resistance reference value is halved for each 20 °C rise in ambient temperature. If the reference resistance val ue is not attained, the winding is too damp and must be oven dried. Oven temperature should be 90°C for 12-16 hours followed by 105°C for 6-8 hours. 电机启动 Motor starting ①单速电机启动(直接或Y/ ?启动) 标准单速三相异步电动机的出线盒内有6个接线头和至少1个接地接头, 接地须根据操作规程在电机接上电源前进行,接线方式和电压应根据接线指示牌及铭牌指示。 Start of single speed motor (Direct-on-line or star/delta start ing) The terminal box on standard single speed motors normally conta ins 6 winding terminals and at least
