EMERSONWM4130EMERSONWM4130由三个频率相同,振幅相等,相位依次互差120度电角度的交流电势组成的电源称为三相交流电源。它是由三相交流发电机产生的。日常生活中所用的单相交流电,实际上是由三相交流电的一相提供的,由单相发电机发出的单相交流电源现在已经很少采用。三相交流电较单相交流电有很多优点,它在发电、输配电以及电能转换成机械能等方面都有明显的优越性例如:制造三相发电机、变压器都较制造容量相同的单相发电机、变压器节省材料,而且构造简单,性能优良,又如,由同样材料所制造的三相电机,其容量比单相电机大50%,在输送同样功率的情况下,三相输电线较单相输电线可节省有色金属25%,而且电能损耗较单相输电时少。由于三相交流电有上述优点所以获得了广泛的应用。正弦交流电是指电路中的电流、电压及电势的大小都随着时间按正弦函数规律变化,这种大小和方向都随时间做周期性变化的电流称交变电流,简称交流。交流电可以通过变压器变换电压,在远距离输电时,通过升高电压可以减少线路损耗。而当使用时又可以通过***变压器把高压变为低压,这既有利安全,又能降低对设备的绝缘要求。此外,交流电动机与直流电动机比较,则具有构造简单,造价低廉,维护简便等优点。在有些地方需要使用直流电,交流电又可通过整流设备将交流电变换为直流电,所以交流电目前获得了广泛地应用。交流电在变化过程中,它的瞬时值经过一次循环又变化到原来瞬时值所需要的时间,即交流电变化一个循环所需的时间,称为交流电的周期。周期用符号T表示,单位为秒。公司聯络人:小李(销售工程师)][销售***电话:0591-62182520][销售***手机:13696852881][销售******:1273632994]HONEYWELLDCS51304338-100K150A-241746-NI4GECIRCUITBOARD44B399241-001/44A399724-G01*NEW*RD-053KUKACP5614C79039-A8000-E077-02-SA413005008Westinghouse1B30023H0111336F-B125-AA-EN-L4RAC3.1-150-460-A0I-W1-220Honeywell621-6300505-6108BGE469-P5-HI-A20-E1RD-053OMRONE2E-X2D1-M3GUSPPE2EX2D1M3GAB1768-L45/BCompactLogixProcessor3MBMFG2011XC3042-70PC84IXilinx3HNA005994-001LOWERSUSPENSIONHONEYWELL51304485-100供应YASKAWA安川伺服电机SGMAS-02A2A21MM-FMFK-000AB模块1785-L40EF施耐德PLCTWDLCAA40DRFAB1746-NI4SERB1746N141746NI4NIBFS2008/2010KVS-4A-BAB2711-T5A5L1PANELVIEW550SERIESBFBM204卡件P0914SY3HNM03545-1BOOT1756-PA75RPCI-6115AllenBradleyAB1336S-BRF50VSDriveMCC***et15AAllenBradley1746-HSCE2Multi-ChannelHiSpeedCounter1029DTOSHIBA***334HS***334H*SKOLLMORGENDH083A1312105X00105G0792-01203-02GE断路器SFHA36AT0250FORCESPARC/CPU-5V/64-110-2MICROSPARC-IIHONEYWELL620-0036POWERSUPPLYMODULEABBPM511V161?Allen-Bradley-741746-P2CNEWREXROTHCONTROLVALVEPOPPETMNR:5610111100德国萨姆森阀门***器3730-01000000000000000.01IS215UCVEM06ASGM-02A314ACAB1756-RM/A模块1769-L32E140***O02000PH266-01GK-C5IC693MDL390RRMSD043A1XXAllenBradley2711-K9C1FQM1S-MC2331771-P7XVME-655XPEBLUL1000000Z05CREGUARDMASTERLTD440F-M1010BYNNUSPP440FM1010BYNNAPPLIEDMATERIALS0010-A7810140NOM25200CDAYTON3N350CNEWALLENBRADLEY1747-ASBREMOTEI/OADAPTERMODULE1746sc-INO4vi140CPU53414A1140CRP93100BAILEYIEMMU21PHOTOSWITCH43GT-TRC30SLNSFP43GTTRC30SL6FC5210-0DA20-2AA1SCHNEIDER(施耐德)140CRP9310031746-NI8IC200UEX214140NOE771011336F-B125-AN-EN-L9ETAU-6208DSL7-10ABB3HAC025917-0011VDIF1130123BSE020514R1IC697MDL350DB-2620AAB,PanelView600,2711-K6C1,VeryGoodConditionTOKYOELCTRON3281-000227-11ALLENBRADLEY800T-J2KT1ANSPP800TJ2KT1AXBTZGM32DTRON08.1AeroflexFMAM15001KOLLMORGENINDDBZX55C39FOXBOROFBM207C1Pre闪存卡2MTSXMFPP002MALLENBRADLEY17710BD10-60VDCOUTPUTMODULE(NEW)STECSEC-4400RC/MC3VDI7777L041C31161G026SE7090-0XX84-3EH0AB1756-L64/B1756L64ControlLogixLogix5564Processor16MBMemoryAB1734-232ASC模块6FC5210-0DA21-0AA1802TL1AB802TL1GP2301-S***1-24V日本原装Pro-face普洛菲斯触摸屏PG3850-400-G140CPU67160140ACI030003G2A5-PS223-E01施耐德PLCTSXDET824VDIPF1677SIEMENS545-110513HNM09234-1APPLICATOR-GUN1746-A71747-L551AllenBradleycontrolpanel/combostarterSize1TESTEDAB1747-L543SLC500PROCESSORSERIESB070812052224DH7721X1-A132B2291X042CIAII2IC693MDL655RRCABLE,SERVO,BOSCHREXROTHINDRAMAT,4103,FEEDBACK,10METERAM0984AT2DSQC2231756-CNBRIC693ACC3151756-L13AllenBradleyAuxiliaryContactBlock#1495-N12~New6ES7322-8BH01-0AB01756-N2ETC902-NSCP-LBaslerSolidStateProtectiveRelayBE1-32RPowerRelay1770-KF3900ETC-R020HZF01.1-W025NREXROTHMHD112B-058-PP1-BNYW80C196NU50INTEL1756-PB75M224-000REXROTH0-810-090-101USPP0810090101Westinghouse405A662H011FANUC控制器发那科A06B-6093-H1011756-PA752711-K6C10ALLENBRADLEY800T-X700E/GREE?N-LAMP-TESTNSPP800TX700E...XBDAWT-0-7D3-Q40-0HCREELTD16310-71-16209-2039-1MM-PM10-200SEC-4400MCN21SLMIC697PWR7481746-RT25R140CRP811003HAB3126-1ParallelarmMVME-147-023XREWHT-L1-5B-Q4CREELTDDSDP170DLM02SO32-10501746-OW161772-LG51305072-200I/OCard,CLCNA,ECBoschRexrothDirectionalControlvalve0810000446/WV10P1N411.0VDIPF0102ALLENBRADLEY1336-SN-SP15ANSFP1336SNSP15A1756-ENBT/A3HNM14127-12K-MIXER,BASICALLENBRADLEY800T-X547JUSPP800TX547JDSQC3323HAB9669-1ALLEN-BRADLEY2711-T10C1L1/F2711T10C1L1SERIESF140ATI03000IC200MDL650)
