Tiv tauj network - yog dab tsi? Nta Lem catenary railway, tram los yog trolleybus

Infrastructure fais dov tas yuav hu rau ntawm lub network. Tsaug rau no kev yog DVR mov phiaj tam sim no lolus, uas, nyob rau hauv lem, tsav lub tsheb. Muaj ntau ntau hom ntawm tes hauj lwm, tab sis lawv sawv cev rau ib tug set ntawm cables, kho thiab txhawb cov ntsiab muab hwj chim ntawm lub fais substations. Tsis tas li ntawd, cov kev sib cuag network kuj yog siv rau txij nkawm ntawm nyob ruaj ruaj khoom, nrog rau ntau yam lem thiab teeb pom kev zoo nroj tsuag.

General ntaub ntawv hais txog kev tiv tauj tes hauj lwm

Nws yog ib feem ntawm cov kev cov vaj tse, uas yog ib feem ntawm ib tug complex ntawm electrified lem thiab txoj kev. Lub hom phiaj tseem ceeb ntawm no infrastructure yog mus rau kis tractive hwj chim ntawm lub substation mus rau lub fais dov Tshuag. Nyob rau hauv thiaj li yuav xyuas kom meej zog mov khoom los ntawm ntau yam substations hu network yog muab faib ua ob peb seem. Yog li, muaj ib tug tsim ntawm khej, txhua tus uas yog noj los ntawm ib tug nyias muaj nyias ib feeder los ntawm ib tug kev qhov twg los.

Partitioning kuj yog siv los pab txhawb txij nkawm ua hauj lwm. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj rau lub hwj chim kis kab yog haujlwm ntawm tsuas yog ib qhov chaw. Faulty thaiv, yog tias tsim nyog, yuav tsum tau txuas mus rau ib tug ua hauj lwm substation, uas yuav txo downtime. Nyob rau hauv tas li ntawd, cov kev sib cuag network ntawm railways los ntawm tshwj xeeb insulators. Qhov kev txiav txim yog vim lub fact tias cov lo arcing thaum lub sij hawm ntawm dua tam sim no lolus tej zaum yuav txhaum qhov yooj yim txheej ntawm cov nyob ntawm tej.

Tus ntaus ntawv catenary

Tes hauj lwm ntawm no hom yog ib tug txheej ntawm hluav taws xob infrastructure Cheebtsam. Nyob rau hauv kev, ib tug raug ntaus ntawm cov qauv no muaj xws li hwj chim cables, tshwj xeeb ncua, thiab tshwj xeeb haum ib feem thiab txhawb lug. Rau hnub tim, thov qhia, nyob rau hauv raws li lub ntsiab lus ntawm uas, catenary nyob ntawm tej thiab fittings yauv ib tug tshwj xeeb txoj kev thermal diffusion galvanizing. Hais thiab me me carbon steel raug mus rau ib tug tiv thaiv kev kho mob rau kom muaj zog thiab durability kev sib txuas lus.

Nta cua catenary

Cua network feem ntau vim rau qhov chaw-saving thiab ntau npaum hluav taws xob kab. Txawm li cas los, muaj drawbacks ntawm xws li ib tug ntaus ntawv, uas yog qhia nyob rau hauv cov nqi siab dua rau installation thiab cov txij nkawm. Yog li, lub nyiaj siv ua haujlwm hu network muaj xws li ib ncua kev kawm cable, fittings, nyob ntawm tej, sub nrog cov kev sib tshuam, zoo li insulators.

Lub ntsiab yam ntxwv nta ntawm tes hauj lwm ntawm no hom yuav txo mus rau ib tug txheej txheem ntawm cov kev pab. Kev sib txuas lus dai rau tshwj xeeb kev txhawb zog. Nyob rau hauv no installation ntawm cov ntsiab lus yuav tsum khij sagging nyob ntawm tej. Tshem tawm no kho raws tsis tau, tab sis nws muaj peev xwm ua rau puas tsuaj rau hwj chim kav. Piv txwv li, yog tias ib tug hu rau network kev pab txhawb nqa tso cai muaj zog sagging, ces mus raws cable collector nyob rau hauv lub hauv av ncua kev kawm ntawv yuav tsis tau nrog lawv kab.

Tiv tauj network ntawm railways

Nyob rau hauv cov ntaub ntawv no peb yuav sib tham txog cov classic version ntawm cov kev sib cuag network. Nws Railways ntiav coob tagnrho cov ntaub ntawv rau electrification u. Ib tug hlau rau tej lub hom phiaj yog ua los ntawm ib qho nyuaj twv electrolytic tooj liab tus ntoo khaub lig-sectional cheeb tsam ntawm 150 mm ^2. Nrog kev xav txog cov kev pab txhawb nqa cov ntsiab, hu rail network yog muab nrog qhob los yog hlau sib, uas nws qhov siab yuav mus txog 15 m Team sib ntawm cov huab paths axis mus rau lub txheej sab ntawm txoj kev txhawb zog rau tus noj thiab spans yog tsis ntau tshaj 310 cm Txawm li cas los, muaj kev zam - .. Piv txwv li, nyob rau hauv raug kev txom nyem technology tso cai rau lub txo lub sij hawm rau 245 cm txoj kev tiv thaiv cov nyob ntawm tej ntawm lub hom siv los ntawm cov pa -. division rau hauv nyias muaj nyias ib seem, qhov kev siv ntawm insulators thiab nruab nrab inserts.

Tiv tauj trolleybus network

Piv rau tsheb nqaj hlau thauj trolley zog tsis xav tias ib qhov hluav taws xob kev twb kev txuas nrog qhov chaw. Tsis tas li ntawd muaj zog yuav tsum tau rau maneuverability, uas ua rau cov kev hloov nyob rau hauv lub koom haum ntawm electrification infrastructure. Cov kev txawv no thiab nrhiav lub ntsiab feature ntawm hluav taws xob rau trolley tsheb npav - lub xub ntiag ntawm ob-wired kab. Nyob rau hauv tas li ntawd, txhua hlau yog tsau nrog me me Team sib thiab yog muab nrog txhim khu kev qha rwb thaiv tsev. Raws li ib tug tshwm sim, lub network yuav nyuab thiab cov kev sib cuag nyob rau hauv lub ncaj seem, ceg, thiab nyob rau hauv ib ncig chaw thiab cov kev sib tshuam. Qhov tshwj xeeb nta yuav ntaus nqi thiab lub thoob plaws siv partitioning nrog lub duas paub insulators. Tab sis nyob rau hauv cov ntaub ntawv no, lub plhaub tsis tau tsuas yog tiv thaiv cov nyob ntawm tej los ntawm kev hu txhua lwm yam, tab sis kuj yuav tiv thaiv cov ntaub ntawv uas nyob rau cov kev sib tshuam. Nyob rau hauv tas li ntawd, cov infrastructure ntawm trolleybus tes hauj lwm yuav tsis pub rau siv hneev nti collector thiab pantographs.

Tiv tauj network ntawm trams

Lub tram tes hauj lwm, hu rau ntawm tej, yog feem ntau yog siv tooj liab thiab zoo sib xws yam ntxwv rau alloys. Tsis tas li ntawd, nws tsis tiv thaiv kom txhob siv los ntawm steel-txhuas conductors. Conjugation ntawm khej nrog txawv qhov siab ntawm qhov kev ncua yog ua nrog ib tug xav ib tog xov nrog hwm rau longitudinal profile ntawm txoj kev. Yog li qhov hloov tus nqi tej zaum yuav txawv los ntawm 20 mus rau 40% nyob rau hauv lub complexity thiab cov tej yam kev mob ntawm cov kab feem gasket. Nyob rau straights lub tram network ntawm hu nyob rau hauv ib tug zigzag yam. Nyob rau hauv cov kauj ruam no zigzag - hais txog ntawm lub ncua kev kawm ntawv - tsis ntau tshaj plaub spans. Nws yuav tsum tau muab sau tseg thiab tus nqi ntawm kev sib cuag cables departing los ntawm cov susceptor axis - qhov no tus nqi yog feem ntau tsis ntau tshaj 25 cm.

xaus

Dua li ntawm qhov kev siv technology tshiab txoj kev loj hlob ntawm electrification, hu rau tes hauj lwm nyob rau hauv loj constructional variants khaws ib pa apparatus. Cov kev hloov nyob rau hauv cov nqe lus ntawm kev txhim kho ntawm kev thiab ua hauj lwm zoo tsis muaj kev cuam tshuam tsuas tej yam hauv daim ntawv thov kom paub meej. Nyob rau hauv kev, cov kev sib cuag network ntawm railways yog nce nkag nrog cheebtsam uas tau dhau mus lawm thermal diffusion galvanizing. Ntxiv ua caij hauv paus, ntawm chav kawm, pab txoj kev cia siab rau thiab durability ntawm cov kab, tab sis lub radical kev txhim kho txhawb rau ib tug tsawg heev degree. Tib yam siv rau lub tram, thiab trolley fais tes hauj lwm, nyob rau hauv uas, li cas los xij, tsis ntev los ho paub kho ntaus ntawv thiab lub dag lub zog qhov cuab lub zog qhov chaw tshem tawm lug.
