东方日立高压变频用户使用手册
东方日立（成都）电控设备有限公司高压大功率变频器HI系列用户使用说明书( Ver.A )目录1．简述 (3)2．变频装置和外部的接口信号列表 (4)3．变频操作 (7)3.1 互锁 (7)3.2 电机速度控制 (7)3.3 启/停变频器的操作流程 (8)4．显示界面 (11)4.1 条形图 (11)4.2 故障显示 (13)4.3 互锁纪录显示 (17)4.4 DIO（输入和输出接触点显示）界面 (18)附：常见故障及处理 (19)1、简述日本日立公司生产的High V oltage Inverter产品是一种交流电机的速度调节控制装置。
变频器的控制方式采用多级PWM叠加技术，结构采用多个变频器单元串联叠加输出的方式。
日立公司的6KV（10KV）系列变频器每相5（8）级单元，变频器输出电压由所有单元输出叠加而成，波形非常接近于正弦波，谐波含量很低，极大的减小了对交流电机的谐波污染。
整套变频装置由旁通柜，变压器柜，功率单元柜和控制柜四部分组成。
在旁通柜内，装有高压断路器和隔离刀闸等，可实现变频和工频的切换，当变频器在运行中发生重故障时，变频器发出变频切换到工频的指令，也可根据需要，人为的切换到工频。
在变压器柜内，装有多重移相变压器，原边绕组采用星形接法，副边绕组采用延边三角形接法和星形接法，可有效的抵消电网中的偶次谐波，并可有效的滤除某些奇次谐波，尽量减少变频器电源的谐波污染，变压器能承受系统过电压和变频装置产生的共模电压以及谐波的影响。
在功率单元柜内装有功率单元，变频器的输出电压为每个单元输出的PWM波形叠加后的输出。
在控制柜内，装有控制各个回路启停的开关和控制各个功率单元协调工作的控制板，以及整套变频装置同外部系统的接口等。
对变频器的启停操作，通过切换开关，既可以通过就地的按钮控制，又可通过远方的DCS控制来完成。
变频装置根据DCS给出的速度调节信号自动的控制电机的转速，并且在就地和远方都可以监视变频装置的状态。

SJ300型日立变频器操作说明该变频器采用“标准数字操作器OPE--S”，内部参数我厂已经设定，出厂时设定为“就地”操作，但只需简单调试就能实现“就地/集控”的操作转换。
一.就地操作
按“功能键”显示“d001”，按“向下键”直至显示“A- - -”, 按“功能键”显示“A001”，再按“功能键”显示“01”，按“向上键”显示“02”频率由操作器设定，按“存储键”确认。
按“向上键”显示“A002”，按“功能键”显示“01”，再按“向上键”显示“02”运行指令由操作器控制，按“存储键”运行键指示灯亮。
输出频率由F001设定，出厂时设定为50Hz。
按“功能键”显示“A- - -”, 按“向上键”直至显示“d001”输出频率监视，再按“功能键”显示“”即为输出频率，“就地操作”设定完毕。
按“运行键”电动机运行，按“停止/重置键”电动机停止。
二.集控操作
按“功能键”显示“d001”，按“向下键”直至显示“A- - -”, 按“功能键”显示“A001”，再按“功能键”显示“02”，按“向下键”显示“01”频率设定由控制端子操作，按“存储键”存储参数。
按“向上键”显示“A002”，按“功能键”显示“02”，再按“向下键”显示“01”运行指令由控制端子操作，按“存储键”确认。
4-20mA控制频率时设定：A101=0、A102=50、A103=20、A104=100。
按“功能键”显示“A- - -”, 按“向上键”直至显示“d001”输出频率监视，
再按“功能键”显示“”即为输出频率，现在“频率”的高低由DCS系统4－20mA 信号控制，“集控操作”设定完毕。
合上Q3（控制柜内C45单极空气开关）变频器即为“集控”运行，这时电动机的“起动/停止”及“转速”均由DCS系统控制。
*说明：电机正反转以集控为准，就地控制的转向可通过F004设定，“00”为正转；“01”为反转。
采用默认值时为正转。
