信號機的設(shè)置SignalSetting天津鐵道職業(yè)技術(shù)學(xué)院聯(lián)鎖與軌旁信號設(shè)備維護信號機的設(shè)置車站設(shè)進站、出站信號機。根據(jù)需要，作業(yè)量較大的車站可設(shè)進路信號機、調(diào)車信號機和復(fù)示信號機。作業(yè)較為單一的中間站、越行站列車進路上可不設(shè)調(diào)車信號機。（一）進站信號機設(shè)置進站信號機的設(shè)置位置應(yīng)符合現(xiàn)行《鐵路技術(shù)管理規(guī)程》的相關(guān)規(guī)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(gòu)外緣與接觸網(wǎng)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(dāng)矮型進站信號機設(shè)于線路右側(cè)時，定型配置的三、四燈位機構(gòu)換位，使紅燈位于線路側(cè)，如圖8-29所示。進站信號機不應(yīng)設(shè)置在電分相區(qū)及附近一定范圍內(nèi)，因為電分相區(qū)一般設(shè)置在區(qū)間，為無電區(qū)，當(dāng)采用無電過分相方案時，信號機的設(shè)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(qū)。因此信號機不能設(shè)置在分相區(qū)內(nèi)，還要考慮距分相區(qū)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(qū)。在進站信號機外方900m、1000m、1100m處應(yīng)設(shè)置預(yù)告標(biāo)。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(shè)置出站信號機應(yīng)設(shè)在距警沖標(biāo)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(yán)重偏置等情況時，可采取按客貨共線標(biāo)準(zhǔn)將出站信號機設(shè)在距警沖標(biāo)5m的地點、優(yōu)化出站信號機外方應(yīng)答器布置以及在相應(yīng)股道中部增加校核列車位置的無源應(yīng)答器組等措施，經(jīng)報部批準(zhǔn)后實施。出站信號機及發(fā)車進路信號機采用“紅、綠、白”三燈位矮型信號機。與傳統(tǒng)的出站信號機不同，增加了引導(dǎo)信號，可以在因發(fā)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(dǎo)方式將列車發(fā)至區(qū)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(dǎo)信號，點亮紅色燈光和月白色燈光。

（三）調(diào)車信號機設(shè)置根據(jù)需要設(shè)置調(diào)車信號機，常態(tài)為一個藍色燈光。正線上無特殊需求不設(shè)調(diào)車信號機。動車組運行徑路上的調(diào)車信號機應(yīng)設(shè)在距警沖標(biāo)不小于5m處。其他徑路上的調(diào)車信號機應(yīng)設(shè)在距警沖標(biāo)不小于3.5m處。設(shè)有調(diào)車危險應(yīng)答器的調(diào)車信號機應(yīng)盡量遠離警沖標(biāo)或防護道岔。調(diào)車信號機應(yīng)采用現(xiàn)行規(guī)定的矮型調(diào)車信號機。盡頭到發(fā)線上阻擋列車運行的調(diào)車信號機采用出站信號機機構(gòu)并封閉綠色燈光。
