锅炉房供电系统高压电源的选择VIP免费

锅炉房供电系统高压电源的选择供热锅炉房工程直接关系到普通百姓的正常生活，它的重要性是显而易见的；另外，由于在系统正常运行时，如果系统停电，直接威胁外网供水管路的安全，所以根据当地的实际情况，该系统采用双回10kv电源，一回运行，一回备用。Heatingboilerroomprojectisdirectlyrelatedtothenormallifeofthecommonpeople,itsimportanceisobvious;Inaddition,duetothesystemduringnormaloperation,ifthesystemoutage,directthreattothesafetyofwatersupplypipesnetwork,soaccordingtolocalactualsituation,thesystemUSESdouble10kvpowersupply,onerun,onestandby.3低压供电系统方案的确定http://www.taqtjxpj.comhttp://www.sddlgs.comhttp://www.shanguo0538.comhttp://www.xintainz.com3theschemedeterminationoflowvoltagepowersupplysystem.3.1负荷初步统计3.1loadpreliminarystatistics补偿前各设备组的计算负荷Beforethecompensationcalculationloadofeachequipmentset一号锅炉的计算负荷为773.2kw；二号锅炉的计算负荷为773.2kw；公共部分的计算负荷为330.65kw。Computationalloadofboilerno.1to773.2kw;No.2boilerinthecomputationalloadof773.2kw;Thehttp://www.taqtjxpj.comhttp://www.sddlgs.comhttp://www.shanguo0538.comhttp://www.xintainz.compublicpartofthecalculationloadis330.65kw.3.2初步确定低压供电系统方案3.2preliminarydeterminelow-voltagepowersupplysystem由于锅炉房系统运行本身的高可靠性，要求系统在一台炉故障或供电系统部分故障等严重的情况下，应保证不造成大的经济损失，并能维持系统最基本的运行。如在全部或部分锅炉故障的情况下，最基本的要求是要保证水循环系统的正常运行，否则有冻坏管路的危险，造成的损失可能是无法弥补的。反应在供电系统方面，就需要选用两台变压器分列运行的系统，并设置联络开关，这样，在一台变压器故障的情况下，另一台变压器可保证供暖系统最基本的运行。另外考虑到每台锅炉系统运行的可靠性，每台锅炉的负荷应由一台变压器供电。Duetothehighreliabilityoftheboilersystemoperationforsystemfailureorapowersupplysysteminafurnacepartsundersevereconditionshttp://www.taqtjxpj.comhttp://www.sddlgs.comhttp://www.shanguo0538.comhttp://www.xintainz.comsuchasfault,shallensurethatdonotcauselargeeconomicloss,andcanmaintainthebasicoperationsystem.Asinthecaseofallorpartoftheboilerfailure,themostbasicrequirementistoguaranteethenormaloperationofthewatercyclesystem,orareindangeroffreezingpipes,thecauseofthelossmaybeirreparable.Responseintermsofpowersupplysystem,youneedtochoosetwotransformerswereoperatingsystem,andsetupthecontactswitch,so,inthecaseofatransformerfault,theotheratransformercanguaranteetheoperationofheatingsystemisthemostbasic.Alsoconsideringtheperboilersystemrunningreliability,perboilerloadshouldbepoweredbyatransformer.3.3负荷统计及变压器的选择并确定低压供电系统3.3theloadstatisticsandthechoiceoftransformerandlowvoltagepowersupplysystemweredetermined.根据以上的思想及负荷的初步统计结果，按两台变压器http://www.taqtjxpj.comhttp://www.sddlgs.comhttp://www.shanguo0538.comhttp://www.xintainz.com进行负荷计算，一台变压器（一号变压器）负责一号锅炉的供电，另一台变压器（二号变压器）负责二号锅炉的供电。公共部分的负荷由原有的一台变压供电。无功补偿采用自动补偿屏。Accordingtotheabovethoughtsandthepreliminaryresultsofload,loadcalculationaccordingtotwotransformer,atransformertransformer(1)isresponsibleforboilerno.1powersupply,anothertransformer(transformer2)isresponsibleforno.2boilerofthepowersupply.Thepublicpartoftheloadfromtheoriginalavariablepressurepowersupply.Reactivepowercompensationusingautomaticcompensation.由此可见，选用两台变压...
