信號機的設置SignalSetting天津鐵道職業技術學院聯鎖與軌旁信號設備維護信號機的設置車站設進站、出站信號機。根據需要，作業量較大的車站可設進路信號機、調車信號機和復示信號機。作業較為單一的中間站、越行站列車進路上可不設調車信號機。（一）進站信號機設置進站信號機的設置位置應符合現行《鐵路技術管理規程》的相關規定。進站信號機采用采用“黃、綠、紅、黃、白”五燈位高柱信

號機。橋、隧地段信號機以及高柱信號機構外緣與接觸網帶電部分不符合安全距離要求時可采用七燈位矮型信號機。當矮型進站信號機設于線路右側時，定型配置的三、四燈位機構換位，使紅燈位于線路側，如圖8-29所示。進站信號機不應設置在電分相區及附近一定范圍內，因為電分相區一般設置在區間，為無電區，當采用無電過分相方案時，信號機的設置地點需要符合列車停車后啟動以及啟動后能夠以慣性渡過無電區。因此信號機不能設置在分相區內，還要考慮距分相區一定的距離，該距離要符合列車啟動后能夠以慣性渡過無電區。在進站信號機外方900m、1000m、1100m處應設置預告標。1.HomeSignalSettingThelocationofthehomesignalsshallbeinaccordancewiththerelevantprovisionsofthecurrentRailwayTechnicalManagementRegulations.Thehomesignalsshallbe"yellow,green,red,yellowandwhite"five-lighthighsignals.Seven-lightdwarfsignalscanbeusedwhentheouteredgeofthesignalmechanismandtheoverheadcontactsystemdonotmeetthesafetydistancerequirements.Whenthedwarfhomesignalsaresettotherightoftheline,thethreeandfourlightpositionmechanismsinthestereotypeconfigurationareswitchedsothattheredlightisonthelineside,asshowninFigure8-29.Homesignalsshouldnotbelocatedinandaroundtheelectricneutralsection,astheelectricneutralsectionisgenerallylocatedinthesection,whichisapower-freezone.Whenapower-freeover-phasingschemeisused,thesignalsneedtobelocatedinsuchawaythatthetraincanstartafterstoppingandcancrossthepower-freezonewithinertiaafterstarting.Therefore,thesignalsmustnotbelocatedintheneutralsection,butmustalsobelocatedacertaindistancefromtheneutralsection,sothatthetraincancrossthepower-freezonewithinertiaafterstarting.Warningsignsforapproachingastationshouldbeprovidedat900m,1000mand1100moutsidethehomesignal.SignalSetting

（二）出站信號機設置出站信號機應設在距警沖標不小于55m(含過走防護距離50m)的地點，或距最近的對向道岔尖軌尖端不小于50m的地點。有時受地形地貌、施工條件等限制，遇個別車站股道有效長不足以及站臺嚴重偏置等情況時，可采取按客貨共線標準將出站信號機設在距警沖標5m的地點、優化出站信號機外方應答器布置以及在相應股道中部增加校核列車位置的無源應答器組等措施，經報部批準后實施。出站信號機及發車進路信號機采用“紅、綠、白”三燈位矮型信號機。與傳統的出站信號機不同，增加了引導信號，可以在因發車進路軌道電路故障或出站信號機允許燈光斷絲情況下，以引導方式將列車發至區間。出站信號機必須在要求地面信號機點燈的情況下才能開放引導信號，點亮紅色燈光和月白色燈光。

（三）調車信號機設置根據需要設置調車信號機，常態為一個藍色燈光。正線上無特殊需求不設調車信號機。動車組運行徑路上的調車信號機應設在距警沖標不小于5m處。其他徑路上的調車信號機應設在距警沖標不小于3.5m處。設有調車危險應答器的調車信號機應盡量遠離警沖標或防護道岔。調車信號機應采用現行規定的矮型調車信號機。盡頭到發線上阻擋列車運行的調車信號機采用出站信號機機構并封閉綠色燈光。
