SIW: nws yog dab tsi, cov nta thiab kev zoo

Cov kev kawm ntawm peb cov niaj hnub no sib tham - SIW. Yuav ua li cas yog nws rau koj yuav qhia tau los ntawm lub npe. Nws yog ib tug hnav ntawm insulated theem conductors, tso tseg cov cab kuj zero. Lub insulating cov ntaub ntawv uas yog siv polyethylene, UV resistant thiab weatherproof. Cov neeg xyuas pib yog ua los ntawm txhuas los yog ib tug hlau thereof. Lub hauv paus yog ib feem ntawm seem pes tsawg xyuas pib kis tus hlau tub ntxhais thiab cov windings yog nruj nyob ib ncig ntawm lub txhuas hlau.

Cov yuav txhawb tau insulated SIW siv nyob rau hauv nyiaj siv ua haujlwm kab, thiab ib lub hwj chim fais tshuab siv rau teeb pom kev zoo ntawm ib tug voltage ntawm 1000 V.

zoo

SIP-ntau yam ntawm designs muaj emerged li lwm txoj kev los yug nyob ntawm tej uas txuas mus rau lub insulators. Lawv zoo yog:

• ua hauj lwm txij nkawm yog cheaper;
• ruaj khov tsis nyob rau hauv cov kis ntawm hluav taws xob hwj chim;
• weathering kuj: significantly tsawg adhered daus thiab cov dej khov, siab tshuaj lom neeg kuj mus txhoj puab heev xov xwm kev rho tawm;
• installation yooj yim thiab ceev, nws tsis yuav tsum tau hnyav machinery;
• reactive losses yog txo 3-fold piv rau tsoos nyob ntawm tej rau insulators;
• zuj zus lawm qhov feem pua ntawm tub sab nyiag ntawm hluav taws xob vim txhaum cai kev sib txuas;
• tsis tuaj kawm ntawv ntawm luv luv circuits nyob rau tshooj nyob ntawm tej nyob rau hauv qhov kev txiav txim ntawm cov cua;
• rau lub sij operating tej yam kev mob, koj muaj peev xwm xaiv qhov zoo tshaj plaws hom hlau.

hom cables

SIW - yog dab tsi? Cov lus teb yuav tsum muaj tseeb, yog hais tias peb kwv yees tag nrho cov hom ntawm hais tias tsab xov xwm. Ntau hom txawv structurally thiab cov ntaub ntawv.

1. STS-1 muaj tib theem conductors, tab sis lub voj kev coj tus kheej sib txawv. Nyob rau hauv no embodiment, hauv nruab nrab neeg xyuas pib yog liab qab, thiab kos tus cim nrog ib tug "n" - cais.
2. CIP-2 yog ua tib txoj kev, tab sis cov rwb thaiv tsev yog ib tug crosslinked polyethylene, khaws zoo cov neeg kho tshuab thiab hluav taws xob khoom ntawm ib tug kub ntawm 130 ⁰ C (pa khoom loses nws zoo txawm nyob rau hauv 85 ⁰ C). Cov khoom ntawm no hom yuav siv nyob rau hauv tej yam kev mob ntawm active huab cua.
3. IIB-3 muaj tsuas yog ib cov tub ntxhais uas muaj ib tug steel tub ntxhais thiab yuav siv tau nyob rau hauv lub nyiaj siv ua haujlwm kis tau tus mob hwj chim mus txog 35 kW.
4. SIP-4 thiab 5 - cov khoom muaj conductive nyob ntawm tej nyob rau hauv qhov qhaj ntawv los ntawm tus cab kuj yog pes tsawg. Yog hais tias muaj yog ib lub cim "n", nws hais tias cov ntaub ntawv uas yog ib tug txhuas hlau. Nyiaj Muas nyob ntawm tej yog siv los tsim khoov rau ob sab ntawm cov kis kab mus rau lub chaw vaj tse thiab rau teeb pom kev zoo tes hauj lwm. Sib nrug ntawm no, nws kuj yuav siv tau lwm hom, xws li insulated hlau, 2x16. Qhov kawg tus xov tooj ntawm no txhais tau tias qhov tsawg kawg nkaus seem loj nyob rau hauv square hli.

Ntawm no xws nws txawv - SIW. Yuav ua li cas yog nws, koj twb muaj ib lub tswv yim. Nyob rau hauv tej yam yooj yim cov ntsiab lus, xam tau tias yog los ntawm peb cov khoom yuav muab txhais li cable khoom, muab faib mus rau hauv peb lub nruab:

• nrog liab qab nruab nrab;
• uas raug rho tawm tsis;
• self-txhawb system.

Cia txhua yam nyob rau hauv ntau yam.

nrog liab qab nruab nrab system

SIP twb xub nkag tau rau hauv Fabkis thiab Finland nyob rau hauv lub 50s, thiab tom qab 30 xyoo tau lug kis nyob rau hauv Russia. Qhov no system muaj xws li:

• ib tug nruab nrab cov cab kuj tsis muaj kev rho tawm ntawm txhuas los yog nws alloy nrog cov hlau tub ntxhais;
• txhuas insulated theem conductors (1 mus rau 4), coiled nyob ib ncig ntawm nruab nrab.

Lub system no muaj xws li SIP-domestic hom 1.2 thiab Finnish analog AMKA.

Nruab nrab siv rau dai lub sam xauv nees thiab yog rau tag nrho cov load ntawm lub nro thiab txhua yam lwm yam. Nws yog grounded nyob rau txhua them nyiaj yug rau cov kev tiv thaiv ntawm txoj sia muaj peev xwm, tej zaum nyob rau ntawm lub theem tsis txaus.

raug rho tawm tsis system

Qhov txawv lus dag nyob rau hauv lub fact tias cov cab kuj yog ua nruab nrab neeg xyuas pib cais. Lub system no muaj xws li ib tug self-txhawb insulated hlau-1a, 2a thiab AMKA-T.

Siv ntawm ib tug raug rho tawm tsis tshwm sim los ntawm qhov yuav tsum tau los mus tiv thaiv corrosion nyob rau nqaum chaw los yog nyob rau hauv sib active tej kev kawm. Ib tug tseem ceeb drawback ntawm lub system yog ib tug siab load rau hauv nruab nrab neeg xyuas pib rwb thaiv tsev. Nyob rau hauv nws daim ntawv thov thauj tog rau nkoj spans txo, tsis txhob rhuav tshem cov kev tiv thaiv txheej. Nyob rau hauv tag nrho cov lwm yam mob, ib tug liab qab nruab nrab.

SIW: cov yam ntxwv ntawm ib tug self-txhawb system

Self-txhawb system tsis muaj tus nruab nrab hlau, uas tuav tag nrho cov xov. Nws comprises 1 mus rau 4 tib yam insulated conductors. Qhov no muaj xws li ib tug ib insulated hlau 3 thiab cov mus rau hauv ib nras PAS-4, thiab 5. Tag nrho cov ntawm lawv yog Attendance loaded ntawm ib nro uas tsim ib qho cuab kom zoo dua li lwm hom.

Nws yog pom zoo kom siv cables nrog nruab nrab tub txib kab thiab ub tau txais kev pab. SIP-4, 5 yog qhov zoo tshaj plaws suited rau tsim ceg rau lub tsev thiab xov rau ntawm facades thiab phab ntsa.

General SIP chaw

1. Kev khiav hauj lwm kub - ntau yam -60 ... +50 ⁰ C.
2. Version rau tsis kub tsis txias thiab huab cua txias.
3. Cov tseem mounting ntawm -10 ⁰ C.
4. Kev khiav hauj lwm nrog ib tug warranty lub sij hawm - 5 xyoo, thiab daim ntaub ntawv - mus txog rau 40 xyoo.

Tus ntoo khaub lig seem ntawm nyob ntawm tej SIP yog nyob rau hauv 16-150 ^mm2. Yuav kom nkag mus rau hauv cov lus teb ntawm lub tsev ntawm pub hwj chim nyob rau hauv feem ntau tus neeg mob tsis yog yuav tsum tau raws li qhov tsawg kawg nkaus loj txaus rau spare. Nyob rau npav thawj tug lej qhia txog cov hom hlau thiab ces qhia kom meej lub xov tooj ntawm cores thiab tus ntoo khaub lig-section, piv txwv li, insulated hlau 2x16.

Nyob ntawm tej yog raug rau cov neeg kho tshuab loads. Rau xam ntawm lub dag lub zog koj yuav tsum paub tus luj ntawm insulated nyob ntawm tej, los ntawm uas txiav txim tshwm sim ntsug load. Ntxiv mus, nws tseem ua hauj lwm thiab icing cua quab yuam sawv nyob rau hauv ib tug kab rov tav cov kev taw qhia. Tus luj nyob ntawm tej ntawm tej hom yuav tsum tau txiav txim los ntawm lub rooj.

mounting

Thaiv tsis tau hnyav khoom thiab kev txawj, nws yuav tsum tau nqa tawm ua tib zoo los mus tiv thaiv kev puas tsuaj rau lub rwb thaiv tsev.

Mounted rau tug thiab anchors rau attaching Inker chais, tom qab uas cov nroj tsuag txoj hlua tus thawj coj. Yuav kom nws yog taag thiab cov hlau yog rho, reeling los ntawm cov lus. Nyob rau chais feem ntau thov ib tug tiv thaiv txheej ntawm cov yas. Cov hlau yuav tsum tsis txhob tuaj mus rau hauv kev sib cuag nrog cov av thiab lwm yam khoom. Tsim nro tswj nws magnitude nrog rau cov kev pab ntawm kev seev. Ces tus hlau yog muab tshem tawm los ntawm lub chais thiab yog tsau nyob rau hauv cov zaj ua lub chaw thau nkoj los yog hluav taws xob kab coupling thiab leakproof hlws ris terminals feem.

Ib tug feature ntawm insulated conductors yog muab ib tug txhim khu kev qha hluav taws xob hu los ntawm txoj kev lub tho spikes. Lawv yog ua los ntawm cov terminals. Tau kev cob cog rua nyob: no tsim pub rau muaj kev ruaj ntseg lag luam.

Nqa rau kev txhawb tsau thauj tog rau nkoj thiab lub installation hluav taws xob nyob rau lwm yam kawg ntawm cov phab ntsa bracket siv. Yog hais tias qhov kev ncua deb mus rau lub tsev ib tug ntau, ntsia ib nrab them nyiaj yug uas tus ceev clip.

Qhov twg insulated nyob ntawm tej yog siv

Pw nyob ntawm tej tsis raug nqi ntau npaum li cas. Lub xub ntiag ntawm rwb thaiv tsev tsim ib tug luv luv-Circuit Court kev tiv thaiv nyob rau hauv kev tiv tauj ntawm cov nyob ntawm tej. Lawv yuav tsum tau fastened mus rau phab ntsa ntawm vaj tse tsis muaj insulators. Thaum lub sij hawm installation yuav tsum tau tsawg dua cov kev txhawb zog.

Feem ntau hlau rau lub hwj chim tes hauj lwm los yog rau illumination ntawm ib tug voltage mus txog 1 kV. Cov hlau no yog siv nyob rau hauv kev tsim kho ntawm nyiaj siv ua haujlwm hwj chim kav thiab ceg rau lub tsev thiab domestic vaj tse.

xaus

Tsis li ntawd, ntev dhau los, ob peb cov neeg paub txog cov khoom no raws li SIW. Yuav ua li cas yog nws, peb pom tau hais tias thaum peb pom cov ntau yam zoo nyob rau hauv ntau lub respects tshaj lub outdated cua kab rau insulators. Lub gasket yog ua nyob rau hauv ib tug luv luv lub sij hawm, tsis muaj txoj thiab hnyav khoom, tab sis cov cuab yeej koj yuav tau mus ua kom tiav, thiab tsim nyog electricians yuav tsum tau siab. Polyethylene rwb thaiv tsev yuav tsum tau ceev faj tuav.
