Dab tsi yog Ob Qhov Tseem Ceeb Ntawm Lub Thawv Cov Khoom Muag?

Ib qho yog qhov ua tiav ntawm cov khoom, uas yog, lub plhaub ntawm lub thawv xa khoom thiab nws cov khoom siv cuam tshuam. Qhov thib ob yog cov khoom siv hluav taws xob thiab cov khoom siv cuam tshuam, uas yog, hloov pauv huab cua thiab cov khoom siv uas nws xav tau.

Muaj cov nram qab no nyob rau hauv lub txee. 1. Circuit Court breaker Circuit Court breaker: tsis yog ib qho kev hloov, tab sis kuj yog lub ntsiab ntawm lub hwj chim faib txee. Feem ntau siv yog cov hloov pauv cua, hloov pauv hloov pauv, thiab ob lub zog tsis siv neeg hloov pauv hloov pauv.

1. Cua hloov:

A. Lub tswv yim ntawm huab cua hloov: Cua hloov kuj hu ua cua Circuit Court breaker, uas yog siv los txuas, tawg thiab nqa cov ntsuas kev ua haujlwm tam sim no thiab luv luv Circuit Court, overload thiab lwm yam txhaum tam sim no hauv Circuit Court, thiab tuaj yeem ua rau overload, luv luv- Circuit Court, under-voltage, thiab lwm yam. Nyob rau hauv cov ntaub ntawv no, lub Circuit Court yog sai disconnected rau txhim khu kev qha kev tiv thaiv.

Muaj ntau yam kev tsim qauv ntawm kev sib txuas lus zoo thiab zoo li qub thiab kev sib cuag rods ntawm Circuit Court breakers, tab sis kev txhim kho lub peev xwm tawg ntawm Circuit Court breakers yog lub hom phiaj tseem ceeb. Tam sim no, txoj cai txwv tam sim no ntawm kev txwv lub ncov tus nqi ntawm luv luv-circuit tam sim no thaum tawg los ntawm kev siv cov qauv kev sib cuag muaj qhov pom tseeb ntawm kev txhim kho lub peev xwm tawg ntawm Circuit Court breaker, thiab tau siv dav.

B. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm huab cua hloov: Lub tshuab cua tsis siv neeg hloov pauv kuj yog hu ua lub tshuab hluav taws xob qis hluav taws xob, uas tuaj yeem siv los txuas thiab rhuav tshem lub voj voog, thiab tseem tuaj yeem siv los tswj lub cev muaj zog uas pib tsis tshua muaj.

Nws txoj haujlwm yog sib npaug ntawm qee qhov lossis tag nrho cov haujlwm ntawm cov khoom siv hluav taws xob xws li riam hloov, overcurrent relay, voltage poob relay, thermal relay thiab leakage protector. Nws yog ib qho tseem ceeb tiv thaiv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob tsawg. Lub tshuab hluav taws xob tsis siv neeg hloov pauv muaj qhov zoo ntawm ntau yam kev tiv thaiv kev ua haujlwm (overload, luv luv Circuit Court, tiv thaiv undervoltage, thiab lwm yam), adjustable tus nqi, siab tawg peev xwm, kev ua haujlwm yooj yim thiab kev nyab xeeb, yog li nws tau dav siv tam sim no.

2. Kev tiv thaiv hluav taws xob hloov:

A. Lub tswv yim ntawm kev tiv thaiv kev hloov pauv: Nws muaj kev ua haujlwm ntawm kev tiv thaiv to. Cov neeg yuav mus txawv tebchaws thaum lawv kov cov hluav taws xob nyob kom muaj kev nyab xeeb ntawm tus kheej. Qhov no yog lub luag haujlwm tseem ceeb ntawm cov dej xau tiv thaiv. , kom tsis txhob muaj hluav taws xob poob siab los ntawm tib neeg kov. Nyob rau tib lub sijhawm, nws muaj kev ua haujlwm ntawm tam sim no on-off, overload tiv thaiv thiab luv-circuit tiv thaiv.

B. Lub hauv paus ntsiab lus ua haujlwm ntawm kev tiv thaiv kev hloov pauv:

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov dej xau tiv thaiv. LH yog xoom-sequence tam sim no transformer, uas muaj ib tug hlau core ua los ntawm permalloy thiab ib tug thib ob coil qhov txhab ntawm ib tug annular hlau core los tsim ib tug nrhiav tau. Cov kab hluav taws xob theem thiab cov kab nruab nrab dhau los ntawm lub voj voog lub voj voog kom dhau los ua cov kauj ruam tseem ceeb ntawm xoom-sequence transformer. Lub qhov hluav taws xob tom qab ntawm lub transformer yog qhov kev tiv thaiv ntau yam.

C. Lub luag haujlwm ntawm kev tiv thaiv kev hloov pauv:

1. Thaum cov dej xau lossis qhov ua txhaum hauv av tshwm sim hauv cov khoom siv hluav taws xob lossis cov kab, lub zog hluav taws xob tuaj yeem raug txiav tawm ua ntej tib neeg kov nws.

2. Thaum tib neeg lub cev kov cov khoom siv hluav taws xob, lub zog hluav taws xob tuaj yeem txiav tawm tsis pub dhau 011s, yog li txo qhov kev puas tsuaj ntawm tam sim no rau tib neeg lub cev.

3. Nws tuaj yeem tiv thaiv kev sib tsoo hluav taws los ntawm kev xau.

3. Dual fais fab tsis siv neeg hloov pauv hloov:

Lub tswv yim ntawm ob lub zog tsis siv neeg hloov pauv hloov pauv: ob lub zog tsis siv neeg hloov pauv hloov pauv yog qhov hloov pauv tsis siv neeg rau ob lub zog. Thaum thawj txoj kev ua tsis tiav, lub hwj chim dual tsis siv neeg hloov pauv hloov pauv hloov mus rau txoj kev thib ob kom muab lub zog rau lub nra. Yog tias txoj kev thib ob ua tsis tiav, lub zog hluav taws xob dual Lub tshuab hluav taws xob tsis siv neeg hloov pauv hloov mus rau thawj channel los muab lub zog rau lub nra. Haum rau UPS-UPS, UPS-generator, UPS-mains, mains-mains thiab lwm yam tsis muaj kev cuam tshuam lub zog hloov pauv ntawm ob txoj kev siv hluav taws xob.
