供应gsdq5000水电阻/软起动器

适用于三相交流50hz，额定电压3kv-10kv的大中型鼠笼式异步电动机或同步电动机的软起动与保护装置，尤其是电网容量不足的工矿企业。本产品是通过机械传动装置使串接在电动机定子侧或星点侧的两极板在水电阻中平滑移动，电阻值由最大无级减少直至趋于零，达到均匀改变电阻值的目的，实现电机的平滑起动。l适应全负载条件下起动；l起动电流小，是额定电流的2-3.5倍；l起动平滑无冲击，延长主电机及拖动设备的使用寿命；l起动转矩大，不受电网质量的影响，起动成功率100%；l结构紧凑，自动化程度高，安全可靠，故障率低，节省运行及维护费用；l热容量大，能在短时间频繁起动，提高设备利用率。执行标准：高压开关设备和控制设备标准共用技术要求gb/t11022-1999iec60694∶19963-35kv交流金属封闭开关设备gb3906-2006iec298∶1990水电阻起动器q/xdy02-2005applicabletosoftstartandprotectionoflargeandmedium-sizedcage-modeasynchronousmotororsynchronousmotorofthree-phase50hz,ratedvoltage3kv-10kv,inparticularfortheindustrialandminingenterpriseswithinadequatecapacityofthepowergrids.thisproductcanmakethebipolarplatesconnectedinseriesbesidethestatorandasterismcabinetofthemotormovesmoothlybymechanicaltransmissiondevice,andresistancevaluefromthelargesttotheleast(zero)forthepurposeofchangingtheresistancevalueuniformlyandmakingthemotorstartsmoothly.uapplicabletostartunderfullloadconditions；usmallstartingcurrent,2-3.5timesratedcurrent；ustartsmoothlywithoutimpulseandextendthelifeofthemainmotoranddragequipments；ulargestarttorquewithoutimpulsefromnetworkqualityandstart-upsuccessrateis100%；ucompactstructure,highdegreeofautomation,safeandreliable,lowfailurerateandsavingoperationandmaintenancecosts；uheatcapacity,frequentstartinashortperiodoftimeandimproveequipmentutilization.operationstandards:technicalrequirementshigh-voltageswitchgearandcontrolequipmentstandardsgb/t11022-1999iec60694:19963-35kvmetalexchangeclosedswitchingequipmentgb3906-2006iec298；1990liquidresistancestarterq/xdy02-2005
