Cov qauv sab hauv ntawm lub thawv xa khoom.
Peb feem ntau pom qee qhov kev tsim kho lub thawv rau ntau qhov chaw, muab ntim rau hauv cov xim zoo nkauj.Lub thawv faib khoom yog dab tsi?Dab tsi yog qhov kev siv ntawm lub thawv?Cia peb saib hnub no.
Lub thawv xa khoom, hu ua lub txee faib khoom, yog lub npe dav dav ntawm lub chaw tswj hluav taws xob.Raws li cov kev xav tau ntawm cov xaim hluav taws xob, lub thawv xa khoom yog cov khoom siv hluav taws xob tsawg uas sib sau ua ke hloov cov khoom siv, ntsuas ntsuas, cov cuab yeej tiv thaiv, thiab cov cuab yeej pabcuam hauv lub txee kaw lossis ib nrab kaw hlau.
Ua ntej, kev tsim kho.Cov cuab yeej qhib kev kuaj xyuas → Cov khoom siv tuav → Txee (Kev faib dav dav) Kev teeb tsa yooj yim → Txee (Kev faib dav dav) saum toj no Generatrix Wiring → Txee (Kev faib dav dav) Trision Wiring → Txee (Kev faib tawm dav dav) Kev lees txais kev sib tw.
Kev siv cov thawv ntim khoom:yooj yim rau cov hluav taws xob hluav taws xob, ua lub luag haujlwm ntawm kev ntsuas thiab txiav txim hluav taws xob thiab kev sib kis.Ib qho yooj yim los tswj thiab yooj yim rau kev txij nkawm thaum muaj kev ua haujlwm tsis zoo.Distribution boxes thiab switchboard distribution vouchers yog ua tiav cov khoom siv rau hauv nruab nrab ntawm kev teeb tsa ntawm cov keyboards, meters, thiab lwm yam.
Tam sim no muaj lub zog nyob txhua qhov chaw, yog li cov thawv xa khoom uas ua los ntawm cov hlau phaj tau siv ntau dua.Ua ntej thaum ntxov xyoo 1990, cov thawv ntim ntoo tau siv, thiab lawv cov hloov hluav taws xob thiab cov ntsuas hluav taws xob tsis tshua muaj nyob rau ntawm lub rooj tsavxwm, yog tias tsis muaj kev nyab xeeb, lawv tau maj mam txav mus.Nrog rau txoj kev loj hlob sai ntawm kev faib khoom siv thev naus laus zis, kev nyab xeeb hluav taws xob tseem ceeb heev rau tib neeg lub neej txhawm rau txhawm rau txhim kho cov phaj tiv thaiv thib ob, yog li peb tau tsim cov khoom siv rau cov me nyuam me me thiab thov rau patent.Cov me nyuam me me tuaj yeem hloov kho cov khoom sib txawv thiab ua kom lawv nyob rau tib qhov siab, tom qab ntawd cov phaj tiv thaiv tau teeb tsa kom ua tiav kev nyab xeeb dua.
Lub thawv xa khoom feem ntau muab faib ua ob ntu
Ib qho yog ua tiav cov vaj tsev ntawm lub thawv xa khoom thiab nws cov khoom siv hlau cuam tshuam.
Qhov thib ob yog cov khoom siv hluav taws xob, nrog rau kev hloov, relay, breaker, thiab xaim ect.
Lub txee yog nyob hauv cov khoom hauv qab no:Circuit Court breaker;Hloov tiv thaiv tam sim no;Dual fais fab tsis siv neeg hloov;Surge tiv thaiv ntaus ntawv;Hluav taws xob ntsuas;Ammeter;Voltmeter.
Circuit Breaker:hloov yog qhov tseem ceeb ntawm lub txee faib khoom.
Leak tam sim no tiv thaiv hloov:Nws muaj ob qho tib si kev ua haujlwm ntawm kev tiv thaiv tam sim no thiab lub luag haujlwm tseem ceeb ntawm tus tiv thaiv tam sim no yog ua kom muaj kev nyab xeeb ntawm tus kheej thaum tib neeg kov lub cev nyob thiab muaj kev tsis txaus ntseeg.Yog tias cov khoom siv hluav taws xob tsis zoo insulated thiab xau mus rau lub tsev, cov khoom tiv thaiv xau tseem yuav mus los kom tsis txhob cuam tshuam tib neeg cov hluav taws xob.Nws tseem muaj lub luag haujlwm ntawm tam sim no on-off, tiv thaiv overload, thiab tiv thaiv luv luv.
Dual hwj chim auto-switch:Dual fais fab auto-switch yog lub hwj chim ob-xaiv nws pib-switch system.Haum rau kev hloov hluav taws xob tas mus li ntawm ob lub zog hluav taws xob, xws li UPS-UPS, UPS-generator, UPS-tswj lub zog, thiab lwm yam.
Surge tiv thaiv:Kuj tseem hu ua tus tiv thaiv xob laim, yog ib qho khoom siv hluav taws xob uas muab kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov twj paj nruag, thiab cov kab sib txuas lus.Thaum cov kab hluav taws xob tam sim no los yog qhov hluav taws xob tam sim no tsim nyob rau hauv hluav taws xob hluav taws xob lossis kab sib txuas lus vim muaj kev cuam tshuam sab nraud, tus tiv thaiv hluav taws xob tuaj yeem ua lub shunt nyob rau lub sijhawm luv luv kom tsis txhob muaj kev puas tsuaj ntawm surges rau lwm yam khoom siv hauv Circuit Court.
Surge tiv thaiv:Nws yog hu ua hluav taws xob tiv thaiv, yog ib qho khoom siv hluav taws xob uas muab kev tiv thaiv kev nyab xeeb rau ntau yam khoom siv hluav taws xob, cov twj paj nruag, thiab cov kab sib txuas lus.Thaum lub qhov hluav taws xob tam sim no los yog qhov hluav taws xob tam sim no tshwm sim hauv hluav taws xob hluav taws xob lossis kev sib txuas lus vim muaj kev cuam tshuam sab nraud, tus tiv thaiv hluav taws xob tuaj yeem ua thiab shunt nyob rau lub sijhawm luv luv los tiv thaiv kev kub ntxhov los ntawm kev puas tsuaj rau lwm yam khoom siv hauv Circuit Court.
Watt-teev 'meter':Nws yog ib qho hluav taws xob ntsuas hluav taws xob feem ntau siv los ntawm cov neeg siv hluav taws xob.Nws yog ib qho cuab yeej rau kev ntsuas hluav taws xob, feem ntau hu ua watt-teev meter.
Lub meter ua haujlwm li cas:Thaum lub ntsuas hluav taws xob txuas nrog lub voj voog, cov hluav taws xob sib nqus tsim los ntawm lub zog hluav taws xob thiab cov kauj tam sim no dhau los ntawm lub disc.Cov magnetic fluxes nyob rau hauv ntau theem nyob rau hauv lub sij hawm thiab qhov chaw, thiab eddy tam sim no induced nyob rau hauv lub disc.Lub sijhawm rotating tshwm sim los ntawm kev sib cuam tshuam ntawm cov sib nqus fluxes thiab cov eddy tam sim no ua rau lub disc tig, thiab cov kev sib hloov ceev ntawm lub disc mus txog ib qho kev sib txawv vim qhov kev txiav txim ntawm cov hlau nplaum.
Vim tias qhov sib nqus flux yog proportional rau qhov voltage thiab tam sim no nyob rau hauv Circuit Court, lub disk txav ntawm ib tug ceev proportional rau lub load tam sim no nyob rau hauv nws qhov kev txiav txim.Kev sib hloov ntawm lub disk yog tsav mus rau lub 'meter' los ntawm tus cab.Lub meter qhov taw qhia yog lub zog tiag tiag siv hauv Circuit Court.
Amperometry:Amperometers yog ua raws li qhov kev txiav txim ntawm tus neeg xyuas pib ntawm qhov chaw sib nqus.Thaum ib qho tam sim no dhau mus, qhov tam sim no dhau los ntawm qhov chaw sib nqus nrog rau lub caij nplooj ntoos hlav thiab lub rotating axis, thiab tam sim no txiav cov kab induction.Yog li ntawd, nyob rau hauv lub zog ntawm magnetic teb quab yuam, lub kauj deflects, uas tsav lub rotating axis thiab tus pointer deflect.
Txij li thaum qhov loj ntawm lub magnetic teb quab yuam nce nrog tam sim no, qhov tam sim no tuaj yeem pom los ntawm qhov degree ntawm deflection ntawm tus taw tes.
Voltmeter:Lub voltmeter yog ib qho cuab yeej rau ntsuas qhov voltage.Voltmeter cim: V, muaj cov hlau nplaum ruaj khov nyob rau hauv lub rhiab heev galvanometer.Ib co coil tsim los ntawm cov xov hlau txuas ntawm ob qhov txuas txuas ntawm galvanometer.Lub kauj yog muab tso rau hauv qhov chaw sib nqus ntawm cov hlau nplaum ruaj khov thiab txuas nrog lub pointer ntawm lub rooj los ntawm lub tshuab tsav.
Txawm li cas los xij, cov khoom uas tau hais los saum toj no yog qhov yooj yim tshaj plaws hauv lub thawv xa khoom.Hauv cov txheej txheem tsim khoom tiag tiag, lwm yam khoom siv yuav raug ntxiv raws li qhov sib txawv ntawm kev siv lub thawv xa khoom thiab cov kev xav tau ntawm kev siv lub thawv xa khoom, xws li AC contactor, intermediate relay, lub sij hawm relay, khawm, teeb liab qhia, thiab lwm yam.KNX ntse hloov module (nrog capacitive load) thiab kev soj ntsuam keeb kwm yav dhau, ntse hluav taws xob khiav tawm teeb pom kev zoo thiab kev saib xyuas keeb kwm yav dhau, hluav taws xob hluav taws xob / hluav taws xob saib xyuas thiab saib xyuas keeb kwm yav dhau, EPS fais fab roj teeb, thiab lwm yam.
Los ntawm kev xaiv lub thawv E-Abel, peb tuaj yeem muab koj nrog kev sib dhos thiab ntau tshaj 100 qhov ntau thiab tsawg ntawm lub thawv, uas yuav txo koj lub sijhawm ua haujlwm thiab txuag koj cov nqi.
