Ib qho insulated ntses phaj, tseem hu ua insulated rail sib koom ua ke (IRJ), yog ib lub tsheb ciav hlau sib koom ua ke uas txuas ob lub tsheb ciav hlau xaus thaum hluav taws xob cais lawv ntawm ib leeg. Nws nqa tib lub luag haujlwm txhua yam raws li tus qauv ntses phaj, tab sis ntxiv cov kev taw qhia kev ua haujlwm ntawm kev sib cais cov kab hluav taws xob. Vim tias IRJ ua tsis tiav tuaj yeem nres ob qho tib si tsheb thiab teeb liab, nws cov lus qhia yuav tsum yog qhov tseeb: cov ntaub ntawv, hluav taws xob tsis kam, muaj peev xwm ua haujlwm, kev sib tw tsheb ciav hlau thiab kev teeb tsa txhua yam tau hais tseg. Kab lus no qhia txog cov kev xav tau hauv txoj kev uas tus neeg yuav khoom lossis tus kws kho tsheb yuav siv lawv.
1. Kev tsim kho thiab cov khoom siv
Lub rooj sib txoos IRJ muaj plaub qhov ua haujlwm: cov phaj ntses insulated (sab laug thiab sab xis), qhov kawg insulating - cov ncej haum nruab nrab ntawm txoj kev tsheb ciav hlau, thiab insulating bushes thiab washers ntawm txhua tus ntsia liaj qhov rooj. Cov tuav yog tsim los ntawm siab - lub zog steel, los yog los ntawm kev sib koom ua ke thiab cov khoom siv epoxy uas cov txheej txheej insulating yog ib feem ntawm lub bar nws tus kheej. Nyob rau hauv cov pob qij txha nplaum, cov tuav tau txuas nrog lub vev xaib tsheb ciav hlau nrog siab - lub zog nplaum, uas faib cov clamping sib npaug thiab ua kom cov pob qij txha nruj thiab tsis muaj dej. Standard bolted pob qij txha cia siab rau bolt clamping ib leeg thiab siv qhov twg ceev thiab tonnage qis dua.
2. Cov Lus Qhia Txog Hluav Taws Xob
Rwb thaiv tsev tsis kam, qhuav: yam tsawg kawg 30 megohm rau cov qauv pob qij txha; glued pob qij txha rau mainline thiab siab - siv ceev yog teev ntawm 100 megohm (10 mus rau 8th ohm) los yog siab dua thaum tshiab.
Qhov sib koom ua ke yuav tsum tuav qhov kev tiv thaiv nyob rau hauv qhov kub thiab txias, nag thiab ballast paug; Qhov no yog vim li cas cov kua dej thiab sealing ntawm qhov sib koom ua ke tseem ceeb npaum li qhov sib koom ua ke nws tus kheej.
Xaus-cov ntawv, cov ntoo thiab cov tshuab ntxhua khaub ncaws yog cov khoom siv rwb thaiv tsev: lawv yuav tsum tau teev tseg rau cov kab tsheb ciav hlau thiab rau cov chav kawm hluav taws xob hluav taws xob ntawm cov kab.
3. Mechanical Requirements
Lub luag haujlwm kho tshuab ntawm IRJ yog qhia los ntawm hom kev xeem es tsis yog los ntawm ib daim duab. EN 16843 npog cov kev cai rau cov pob qij txha insulated, suav nrog kev ua haujlwm ntsug ntsug thiab rov ua dua -load (kev qaug zog) pov thawj, yog li tus neeg yuav khoom yuav tsum xav kom cov sib koom ua ke ua hom - sim rau EN 16843 rau cov phiaj xwm kev tsheb nqaj hlau. Tsis tas li ntawd, cov tuav thiab bolts yuav tsum tau muab tso rau hauv seem kev tsheb nqaj hlau: piv txwv li, 60 kg / m sib koom nrog plaub bolts ntawm ib sab ntawm 630 mm bar ntev siv cov ntsia liaj qhov rooj qhov ntau thiab tsawg hauv chav kawm 25-28 mm inch, thiab cov bolted sib dhos yuav tsum tsim lub clamping quab yuam uas xav tau los tiv thaiv kev tsheb nqaj hlau hauv qab braking thiab thermal loads. Glued variant ntxiv cov nplaum nplaum, uas yuav tsum nyob twj ywm nyob rau hauv longitudinal rail rog nyob rau hauv tsis tu ncua welded rail.

FAQ
Q1: Qhov kev tiv thaiv hluav taws xob twg yuav tsum muaj IRJ?
Txheem bolted pob qij txha tau teev ntawm 30 megohm yam tsawg kawg nkaus qhuav; glued pob qij txha rau mainline siv feem ntau teev ntawm 100 megohm (10 mus rau 8 ohm) los yog siab dua. Paub meej tias tus nqi tiv thaiv tus qauv tsim ntawm kab.
Q2: Vim li cas ho xaiv ib qho kev sib koom ua ke ntawm cov hlua khi?
Cov nplaum nplaum ua rau kev sib koom ua ke kom nruj thiab ua kom cov txheej txheem rwb thaiv tsev kaw kom tsis txhob ya raws, muab cov khoom siv hluav taws xob ruaj khov thiab lub neej ua haujlwm ntev dua nyob rau hauv cov tsheb hnyav thiab kev kub ceev.
Q3: Tus txheej txheem twg tswj xyuas cov kab hluav taws xob sib txuas?
TS EN 16843 Cov khoom siv hluav taws xob - Ntu 16843: Cov kev cai ntawm cov pob qij txha thiab cov nplais ntses, suav nrog cov khoom siv thiab hluav taws xob pov thawj. Rail seem lawv tus kheej ua raws li lub teb chaws lossis thoob ntiaj teb cov qauv kev tsheb ciav hlau.
Q4: Puas tuaj yeem muab IRJ rau ob qhov sib txawv ntawm kev tsheb ciav hlau?
Yog, raws li kev sib koom ua ke. Txhua sab yog machined rau nws tus kheej txoj kev tsheb ciav hlau profile kom qhov kev hloov pauv khaws ob qho tib si kev sib tw thiab kev sib cais hluav taws xob, piv txwv li ntawm UIC54 thiab UIC60.
Q5: Kev saib xyuas kev saib xyuas dab tsi khaws IRJ hauv kev pabcuam?
Ntsuas cov rwb thaiv tsev tiv thaiv ntawm lub sijhawm txij nkawm, xyuas lub bolt torque, tshuaj xyuas qhov kawg ntawm insulating -posts, bushes thiab washers for damage, and monitor rail-end batter and gap growth. Rov ua dua qhov sib koom ua ke thaum qhov kev tawm tsam poob qis dua qhov yuav tsum tau ua lossis qhov sib koom ua ke qhia txog kev puas tsuaj.
Q6: Puas yog IRJ bolts xav tau cov ntxhua khaub ncaws tshwj xeeb?
Yog lawm. Insulating bushes thiab washers yog ib feem ntawm lub rooj sib txoos thiab yuav tsum tau muab ntsia rau ntawm txhua tus ntsia liaj qhov rooj; siv cov tshuab ntxhua khaub ncaws yooj yim tsim ib txoj hauv kev uas ua rau luv luv ntawm kev sib koom ua ke thiab rhuav tshem cov kab hluav taws xob sib cais.
