Yuav Ua Li Cas Tiv Thaiv Hluav Taws Xob Thiab Kev tawg ntawm Hlau Thiab Cable

1. Yog vim li cas rau cable tawg thiab hluav taws

Lub rwb thaiv tsev txheej ntawm lub hwj chim cable yog tsim los ntawm ntau yam combustible tshuaj xws li ntawv, roj, hemp, roj hmab, yas, asphalt, thiab lwm yam. Yog li ntawd, lub cable muaj peev xwm ntawm hluav taws thiab tawg. Yog vim li cas rau qhov hluav taws kub thiab tawg ntawm lub cable yog:

(1) Rwb thaiv tsev puas ua rau luv luv-circuit txhaum. Kev tiv thaiv cov tawv nqaij ntawm lub hwj chim cable yog puas thaum lub sij hawm tso los yog lub rwb thaiv tsev cable yog mechanically puas thaum lub sij hawm ua hauj lwm, ua rau lub rwb thaiv tsev puas ntawm cov cables los yog nruab nrab ntawm cov hlau lead.

(2) Lub cable yog overloaded rau lub sij hawm ntev. Thaum lub sijhawm ua haujlwm dhau mus ntev, kev ua haujlwm kub ntawm cov khoom siv hluav taws xob cable tshaj qhov siab tshaj plaws tso cai rau cov cua sov li qub, uas ua rau cov kab hluav taws xob rwb thaiv tsev laus thiab qhuav. Qhov tshwm sim ntawm kev laus thiab qhuav rwb thaiv tsev feem ntau tshwm sim ntawm tag nrho cov kab cable. Vim qhov kev laus thiab ziab ntawm cov rwb thaiv tsev cable, cov khoom siv insulating poob los yog txo cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, yog li nws nquag tawm tsam los ntawm hluav taws thiab txawm hlawv ntawm ntau qhov chaw raws li tag nrho ntev ntawm lub cable tib lub sijhawm.

(3) Cov roj-immersed cable khiav thiab xau vim qhov siab sib txawv. Thaum cov roj-immersed cable yog nteg nrog qhov siab loj qhov sib txawv, qhov tshwm sim ntawm cov roj ntws los ntawm lub cable yuav tshwm sim. Raws li qhov tshwm sim ntawm qhov ntws, sab qaum ntawm lub cable yog qhuav vim qhov poob ntawm cov roj, qhov thermal tsis kam ntawm qhov no ntawm cable nce, thiab cov ntawv rwb thaiv tsev cokes thiab tawg ua ntej. Tsis tas li ntawd, vim tias cov roj nyob rau sab saud khiav qis, nws ua rau chav nyob ntawm lub taub hau cable sab saud thiab tsim kom muaj lub siab tsis zoo, uas ua rau lub cable yooj yim nqus dej noo thiab ua rau qhov kawg ntub. Qhov qis ntawm cov kab hluav taws xob tsim hluav taws xob zoo li qub vim muaj cov roj sib xyaw ua ke, uas ua rau lub taub hau cable kom cov roj xau. Cov kab ntub dej thiab cov roj xau tuaj yeem ua rau muaj kev tsis ua haujlwm thiab hluav taws kub.

(4) Rwb thaiv tsev tawg ntawm qhov nruab nrab sib koom lub thawv. Qhov nruab nrab ntawm qhov sib koom ua ke ntawm lub thawv cable yog oxidized, rhuab, thiab glued thaum lub sij hawm ua haujlwm vim tsis txaus crimping, vuam tsis muaj zog los yog kev xaiv tsis raug ntawm cov khoom sib koom; thaum ua qhov sib txuas nruab nrab ntawm lub cable, qhov zoo ntawm tus neeg sawv cev insulating nchuav rau hauv lub thawv sib koom ua ke tsis tau raws li qhov yuav tsum tau ua. Nws yuav tsum tau hais tias thaum lub insulating tus neeg sawv cev yog poured, muaj cua qhov nyob rau hauv lub thawv thiab lub cable lub thawv yog tsis zoo kaw los yog puas thiab xau rau hauv cov dej noo. Cov yam ntxwv saum toj no tuaj yeem ua rau rwb thaiv tsev tawg, ua rau luv luv, thiab ua rau lub cable tawg thiab ntes hluav taws. (5) Lub taub hau cable hlawv. Vim hais tias qhov saum npoo ntawm lub taub hau cable yog ntub thiab qias neeg, lub tes tsho ceramic ntawm lub taub hau cable tawg thiab qhov kev ncua deb ntawm cov hlau lead yog me me dhau, uas ua rau hluav taws kub nyhiab, ua rau cov nplaim hluav taws xob ntawm lub taub hau cable thiab cov rwb thaiv tsev ntawm lub taub hau. cov hlau lead los hlawv.

(6) Sab nraud qhov hluav taws kub thiab qhov hluav taws kub ua rau hluav taws kub. Xws li kev sib kis ntawm cov hluav taws kub hauv cov roj, kev sib kis ntawm kev tawg thiab hluav taws ntawm cov roj hluav taws xob hluav taws xob, kev sib txuas ntawm cov roj pulverized nyob rau hauv lub boiler pulverizing system los yog cov thee conveying system, lub ci ntawm cov kub kub chav pipeline, cov tshuaj corrosion ntawm cov kua qaub thiab alkali, vuam sparks thiab lwm yam hluav taws kub, txhua yam tuaj yeem ua rau hluav taws kub.

2. Txoj kev tua hluav taws rau cov cables Thaum lub cable ntes hluav taws, cov hauv qab no yuav tsum tau siv los muab tso tawm:

(1) Txiav tawm lub hwj chim ntawm cov hluav taws xob cable. Yog hais tias lub cable ntes hluav taws, txawm yog vim li cas, lub hwj chim mov yuav tsum raug txiav tam sim ntawd. Tom qab ntawd, raws li txoj hauv kev thiab cov yam ntxwv ntawm lub cable, ua tib zoo xyuas kom paub qhov txhaum ntawm lub cable, thiab tib lub sijhawm, cov neeg ua haujlwm yuav tsum tau ceev nrooj los sib ntaus.

(2) Txiav tawm lub hwj chim ntawm cov khoom siv tsis raug cai thaum muaj hluav taws kub hauv lub cable trench. Thaum cov cables nyob rau hauv lub cable trench ntes hluav taws, yog hais tias cov cables nteg ib sab ntawm ib sab nyob rau hauv tib lub trench muaj pom tseeb muaj peev xwm ntawm hluav taws, lub hwj chim mov ntawm cov cables yuav tsum tau txiav tawm. Yog tias cov kab hluav taws xob tau teeb tsa hauv cov khaubncaws sab nraud povtseg, ua ntej txiav tawm lub hwj chim ntawm cov hluav taws xob hluav taws xob saum toj kawg nkaus ntawm cov hluav taws xob hluav taws xob, tom qab ntawd txiav tawm lub zog hluav taws xob ntawm cov kab hluav taws xob los ntawm ib sab nrog cov hluav taws xob cable, thiab thaum kawg txiav tawm lub hwj chim ntawm lub cable. hauv qab ntawm kab hluav taws.

(3) Kaw lub qhov rooj hluav taws ntawm lub cable trench lossis thaiv ob qhov kawg ntawm lub cable trench. Thaum lub cable nyob rau hauv lub cable trench catches hluav taws, thiaj li tsis txhob cua khiav thiab tua hluav taws sai sai, qhov hluav taws kub qhov rooj ntawm lub cable trench yuav tsum tau muab kaw los yog ob qho tag nrho yuav tsum tau thaiv, thiab hluav taws yuav tsum tau extinguished los ntawm suffocation.

(4) Ua haujlwm zoo ntawm kev tiv thaiv tus kheej thaum muab hluav taws xob cable. Txij li thaum hluav taws kub ntawm lub cable yuav tsim cov pa taws ntau thiab cov pa phem, cov neeg ua haujlwm cawm siav yuav tsum hnav lub npog ntsej muag roj thaum tua hluav taws ntawm lub cable. Txhawm rau tiv thaiv tus kheej ntawm hluav taws xob poob thaum lub sijhawm cawm, cov neeg cawm siav yuav tsum tau hnav cov hnab looj tes roj hmab thiab cov khau looj plab. Yog tias ib theem ntawm cov hluav taws xob hluav taws xob hluav taws xob tau pom muaj nyob hauv av, cov neeg cawm siav yuav tsum saib xyuas: Tsis txhob nkag mus hauv tsev hauv 4m ntawm qhov txhaum, thiab tsis txhob nkag mus rau sab nraud ntawm qhov txhaum. Cov ntsiab lus nyob rau hauv 8m, thiaj li tsis mus rau kauj ruam voltage thiab tiv tauj voltage ua mob rau tib neeg. Kev cawm ntawm cov neeg ua haujlwm raug mob tsis txwv rau qhov kev txwv no, tab sis kev tiv thaiv yuav tsum tau ua.

(5) Cov khoom siv tua hluav taws siv los tua hluav taws xob cable. Cov hluav taws tua hluav taws yuav tsum tau siv los tua hluav taws hluav taws xob, xws li cov hluav taws tua hluav taws qhuav, "1211" hluav taws tua hluav taws, cov hluav taws tua hluav taws carbon dioxide, thiab lwm yam; xuab zeb qhuav los yog loess kuj siv tau los npog; yog tias siv dej los tua hluav taws, nws yog qhov zoo tshaj plaws los siv dej tsuag ***; Qhov hluav taws kub hnyiab heev, thiab nws tsis tuaj yeem tso tawm lwm txoj hauv kev. Tom qab qhov hluav taws xob raug txiav tawm, cov dej tuaj yeem muab nchuav rau hauv cov kab hluav taws xob, thiab qhov txhaum tuaj yeem raug kaw thiab tua nrog dej.

(6) Thaum muab hluav taws xob tua hluav taws, nws yog txwv tsis pub kov cov kab hlau txuas ncaj qha thiab txav cov hlua nrog tes.
