供应gdcq-2000电磁/软起动器

将电磁调压器原边串接于电动机定子回路，利用现代控制和电力电子技术，通过电磁感应原理，调控起动调压器副边端电压，从而控制调压器原边端电压从高到低变化，根据串联电路电压分配原理，电动机端电压将从低到高变化，达到软起动的目的。依据以上原理，停车时控制电动机端电压从高到低变化，可实现软停功能。u起动平稳，大大减少对电器和机械设备的冲击，延长设备的使用寿命；u起动电流小，（2ie-3.5ie可调），起动时对电网的干扰大大降低；u根据负载工况可选择三种起动模式，即电压斜坡式，电流恒定式，初始脉冲式；u根据特定需求，可选择软停车功能；u起动参数设置方便，重复性高，控制精度高，稳定性好；u根据用户需要可选配触摸屏或工控机进行组态，实现实时监控；u配有通讯接口，可实现远距离操作和控制；u气候适应能力强（-20°；---45°；），可满足低温环境使用；u常温下可1小时连续起动6-10次；u特别方便实现一台起动器拖带多台容量不同的电动机；u维护简单，使用寿命长，性价比高。执行标准：3-35kv交流金属封闭开关设备gb/t3906-1991电控设备第二部分：装有电子器件的电控设备gb/t3797-1989三相油浸式电力变压器技术参数和要求gb/t6451-1999三相干式电力变压器技术参数和要求gb/t1028-1997系列高压电磁调压软起动装置q/xdy04-2006gdcqscopeapplicabletothefrequency3kv-10kv,200kw-20000kw,three-phaseacmotorsoftstart.workingprinciplesandcharacteristicstheoriginaledgeelectromagneticregulatorwillbeconnectedinserieswithmotorstatorcircuit,usingmoderncontrolandelectricpowertechnology,throughtheprincipleofelectromagneticinduction,toregulateandcontroltheviceterminalvoltageoftheregulator,forthepurposeofcontrollingtheoriginalterminalvoltagedescendingchanges.accordingtotheprincipleofseriescircuitvoltagedistribution,motorterminalvoltagewillchangefromlowtohightomakesoftstart.basedontheaboveprinciple,wecancontrolterminalvoltageofthemotordescendingchangeswhenoperationstopstoachievesoftstop.usmoothstart-upgreatlyreducestheimpulsetoelectricalandmechanicalequipmentsoastoextendtheusefullifeofequipment；usmallstartingcurrent,(2ie-3.5ieadjustable),greatlyreducestheinterferencetotheelectrifiedwirefencewhenstarting；uthreestart-upmodeofchoiceaccordingtoloadcondition:slope-voltage,constant-current,initialpulse；usoft-stoppingfunctionisoptionalaccordingtospecificneeds；uconvenientsetofstartparameters,highrepetitive,high-precisioncontrol,goodstability；uaccordingtouserneeds,touch-screenorindustrialmachineconfigurationareoptionaltomakereal-timemonitor；uwithacommunicationsinterfacetoachievelong-distanceoperationandcontrol；ubetteradapttoclimate(-20º；c---45º；c-)tomeetthelow-temperatureenvironment；uundernormaltemperaturecanstantstartcanbe6-10timesinanhour；uitiseasytorealizethatastarterisusedbymanymotorswithdeffirentcapacity；usimplemaintenance,longlife,cost-effective.operationstandard:3-35kvmetalexchangeclosedswitchingequipmentgb/t3906-1991technicalparametersandrequirementsofthree-phaseoil-immersedpowertransformersgb/t6451-1999technicalparametersandrequirementsofthree-phasedrypowertransformersgb/t1028-1997electronicequipmentpartii:electroniccontrolequipmentequippedwiththeelectronicdevicesgb/t3797-1989gdcqseriesofelectromagneticsurgesoftstarterforhigh-voltagemotorsq/xdy04-2006
