Lub hom phiaj tseem ceeb ntawm qhov hloov pauv hluav taws xob siab

1. Nws yog siv los cais cov khoom siv fais fab kom ntseeg tau tias muaj kev nyab xeeb ntawm kev saib xyuas, yog li ntawd cov khoom siv hluav taws xob uas nyob hauv kev saib xyuas muaj qhov chaw txiav tawm ntawm lub zog fais fab;

2. Ua qhov kev ua haujlwm kaw kom hloov hom kev ua haujlwm ntawm lub kaw lus. Piv txwv li, hauv lub voj voog uas muaj ob lub busbar ua haujlwm, siv lub qhov hloov cais kom hloov cov khoom siv lossis kab ntawm ib pawg ntawm cov busbars mus rau lwm pawg ntawm cov busbars;

3. Nyob rau hauv qee qhov xwm txheej, nws tuaj yeem siv los txuas thiab txiav cov voj voog me me. Yog tias siv lub qhov hloov cais, cov haujlwm hauv qab no tuaj yeem ua tiav:

1) Faib thiab kaw cov voltage transformer thiab arrester circuits.

2) Faib thiab kaw qhov them tam sim no ntawm lub tsheb npav.

3) Cov ntsiab lus, cov transformers tsis muaj load uas nws cov kev sib xyaw ua ke tam sim no tsis tshaj 2A thiab cov kab tsis muaj load uas nws cov capacitive tam sim no tsis tshaj 5A.

Tkev faib tawm ntawm qhov hloov pauv hluav taws xob siab

1. Raws li qhov chaw teeb tsa, nws muab faib ua ob hom: sab hauv tsev thiab sab nraum zoov;

2. Raws li tus naj npawb ntawm cov ncej, nws muab faib ua ob hom: unipolar thiab tripolar;

3. Raws li tus naj npawb ntawm cov ncej rwb thaiv tsev, nws muab faib ua peb hom: ib kab, ob kab thiab peb kab;

4. Raws li cov yam ntxwv ntawm cov qauv, nws muab faib ua peb hom: hom guillotine, hom ntsia hlau thiab hom ntsaws;

5. Raws li cov haujlwm sib txawv, nws muab faib ua ob hom: nrog rau kev hloov riam av thiab tsis muaj kev hloov riam av;

6. Raws li lub tshuab ua haujlwm siv, nws muab faib ua: phau ntawv, hluav taws xob thiab pneumatic ua haujlwm mechanisms.

Qhov tshwm sim tsis zoo thiab kev kho mob ntawm qhov hloov pauv hluav taws xob siab

1. Qhov chaw sib cuag ntawm qhov hloov pauv cais tawm yog overheated

Nyob rau hauv ib txwm muaj xwm txheej, lub qhov hluav taws xob cais yuav tsum tsis txhob kub dhau. Yog tias lub qhov hluav taws xob cais pom tias kub dhau thaum lub sijhawm ua haujlwm, yuav tsum ua raws li cov hauv qab no:

1) Hauv lub kaw lus ob chav busbar, thaum ib pawg ntawm cov busbar disconnectors raug cua sov, nws yuav tsum tau hloov mus rau lwm pawg ntawm busbars; thaum lub kaw lus ib leeg busbar disconnector raug cua sov, sim txo qhov hnyav. Yog tias muaj xwm txheej tso cai, nws yog qhov zoo tshaj plaws kom tshem tawm qhov kev hloov cais tawm ntawm kev ua haujlwm. Yog tias lub zog tuaj yeem raug txiav tawm, nws yuav tsum tau kho tam sim ntawd, txwv tsis pub, kev saib xyuas yuav tsum tau ua kom muaj zog. Yog tias qhov kub hnyav heev, lub circuit breaker sib xws yuav tsum tau txiav tawm raws li cov cai.

2) Thaum qhov chaw sib cuag ntawm lub qhov hluav taws xob cais kab kub dhau, txoj kev kho mob zoo ib yam li lub qhov hluav taws xob cais ib lub tsheb npav, tab sis vim muaj kev tiv thaiv ntawm lub tshuab hluav taws xob hauv series, lub qhov hluav taws xob cais tuaj yeem txuas ntxiv ua haujlwm, tab sis kev saib xyuas yuav tsum tau ua kom muaj zog kom txog thaum lub zog hluav taws xob tuaj yeem kho tau.

2. Rub yuam kev thiab kaw yuam kev qhov hloov cais nrog lub nra

Lub qhov hluav taws xob cais tsis muaj peev xwm tua hluav taws xob, thiab nws raug txwv tsis pub rub lossis kaw lub qhov hluav taws xob cais nrog lub nra. Thaum qhov xwm txheej no tshwm sim, nws yuav tsum tau daws raws li hauv qab no:

1) Rub lub qhov hloov cais tawm los ntawm qhov yuam kev

Yog tias cov hniav nyuam qhuav tawm ntawm ntug ntawm cov hniav (lub arc tau raug ntaus tab sis tsis tawg), lub disconnector uas tsis tau qhib yuav tsum kaw tam sim ntawd kom tsis txhob muaj arc luv luv; yog tias lub disconnector tau qhib, nws tsis raug tso cai kaw, thiab lub disconnector yuav tsum tau ua kom ntseeg tau tias qhib qhov chaw, txiav lub voj voog nrog lub circuit breaker, thiab tom qab ntawd kaw lub qhov hloov cais.

2) Kaw lub qhov hloov cais tsis raug

Tom qab lub disconnector raug kaw yuam kev nrog lub nra hnyav, nws yeej tsis raug tso cai qhib dua, thiab nws yuav tsum tau qhib tom qab lub Circuit Court breaker tau txiav tawm lub Circuit Court.

3. Lub qhov hloov cais tsis kam qhib thiab kaw

1) tsis kam kaw

Thaum lub qhov hloov cais tsis kam kaw vim yog qhov tsis ua haujlwm ntawm lub tshuab, nws tuaj yeem siv nrog tus pas nrig rwb thaiv tsev, lossis yog tias xav kom muaj kev nyab xeeb ntawm tus kheej, siv lub wrench los tig lub qag tig ntawm lub qhov hloov cais.

2) tsis kam qhib

Thaum lub qhov hloov cais tsis tuaj yeem qhib tau, yog tias lub tshuab ua haujlwm khov, koj tuaj yeem co nws maj mam kom pom qhov chaw cuam tshuam. Yog tias qhov chaw cuam tshuam nyob hauv qhov sib cuag ntawm lub qhov hloov, nws tsis tuaj yeem qhib tau, txwv tsis pub lub raj mis porcelain txhawb nqa yuav raug puas tsuaj.

4. Lub qhov hloov pauv cais tawm puas lawm

Yog tias nws yog qhov tso tawm flashover, qhov kev saib xyuas yuav tsum tau ua kom muaj zog, thiab kev ntxuav yuav tsum tau ua tom qab thov kom muaj hluav taws xob tsis ua haujlwm; yog tias lub raj mis porcelain txhawb nqa puas lawm thiab tawg, lub tshuab hluav taws xob yuav tsum tau siv los txiav lub voj voog, thiab lub qhov hloov pauv cais tawm puas lawm yuav tsum tau rho tawm kom kho.
