Dab tsi yog tsawg voltage switchgear

Tsis tshua muaj - voltage ua tiav switchear yog qhov loj- nplai thiab dav siv tag nrho cov khoom hluav taws xob. Nws yog dav siv nyob rau hauv qis - voltage faib cov tshuab ntawm cov nroj tsuag fais fab, kev lag luam, kev lag luam thiab ntau hom power cov neeg siv. Nws ua lub luag haujlwm ntawm kev hloov pauv fais fab, faib, kev tswj hwm, kev tiv thaiv thiab lub zog hluav taws xob, hluav taws xob nyiaj ntsuab, thiab lwm yam.

Tsawg - voltage switchgear tuaj yeem faib ua cov hauv qab no: (Raws li cov qauv tsim qauv thiab siv)

(1) Cov Vaj Huam Sib Luag Tawb Nruab Nrab

Cov vaj huam sib luag tsau hloov pauv feem ntau hu ua transgboard lossis faib cov vaj huam sib luag. Nws yog qhov qhib Switchgear nrog lub vaj huam sib luag. Cov ua ntej muaj kev tiv thaiv kev tiv thaiv, thiab sab nraub qaum thiab sab nraud tseem tuaj yeem kov cov ntu nyob. Qib kev tiv thaiv yog tsawg thiab nws tsuas yog siv tau hauv kev lag luam thiab kev siv cov chaw ua haujlwm ntawm kev sib txuas lus luv thiab kev ntseeg tau.

(2) Nrog hloov pauv

Lub kaw tes hloov rov qab yog hais txog qhov qis - voltage switchgear nrog txhua sab uas muaj cov teeb tsa tshwj xeeb tsuas yog cov teeb tsa sab nraud. Cov hluav taws xob sib xyaw xws li hloov chaw, kev tiv thaiv thiab tswj xyuas kev tswj hwm tau nruab rau hauv lub plhaub kaw lossis insulating tawm tsam phab ntsa lossis deb ntawm phab ntsa. Txhua lub voj voog hauv cov txee yuav tsis ua kom zoo, lossis tuaj yeem raug rho tawm los ntawm cov phaj av hauv av lossis cov hlau insulating.

(3) rho tawm hloov chaw

Hom hloov no siv lub tsev kaw cov vaj tse kaw los ntawm cov phiaj hlau. Cov khoom siv hluav taws xob ntawm cov khoom xa tuaj thiab tawm hauv rho tawm cov tub luam, sib sau ua cov haujlwm ua haujlwm uas tuaj yeem ua tiav qee yam kev ua haujlwm muaj zog. Chav ua haujlwm thiab chav Busbar lossis cable yog sib cais los ntawm kev faib ua ke ua los ntawm cov phiaj av hauv av lossis kev sib sau ua peb thaj chaw: chav tsev tsheb npav, ua haujlwm hauv chav ua haujlwm thiab cable. Kuj tseem muaj kev rho tawm kev ntsuas ntawm txhua lub tsev ua haujlwm. Rho tawm Switchgear tau muaj kev cia siab, kev nyab xeeb thiab interchangeabability. Lawv tsim nyog rau kev siv raws li kev tswj hwm nruab nrab hauv qis - pa hluav taws xob muab thiab faib hluav taws xob muaj kev cia siab yooj yim.

(4) Lub Zog Hluav Taws Xob thiab Teeb Pom Kev Tsav Tsheb

Lub Zog Hluav Taws Xob thiab Teeb Pom Kev Tsav hluav taws xob feem ntau kaw thiab ntsug ntsia. Vim muaj cov xwm txheej sib txawv sib txawv, theem kev tiv thaiv ntawm lub tsev kuj txawv. Lawv feem ntau yog siv raws li cov khoom faib ntawm cov chaw muaj hluav taws xob noj.

Lub ntsiab ntawm cov tsis muaj tsawg - voltage switchgear yog raws li hauv qab no:

• Cov ntsuas ntsuas hluav taws xob, suav nrog cov ntsuas hluav taws xob ntawm cov hluav taws xob tseem ceeb thiab ntsuas hluav taws xob. Cov ntsuas hluav taws xob ntawm cov circuit Court tseem ceeb tau muab faib ua cov ntsuas kev ua haujlwm ntsuas hluav taws xob thiab ntsuas cov ntaub ntawv sib xyaw hluav taws xob. Cov ntsuas ua haujlwm voltage qhia qhov siab tshaj plaws ntawm lub zog hluav taws uas hloov pauv tau nyob; Qhov ntsuas rated voltage yog hais txog tus qauv hluav taws xob tus nqi siv los ntsuas cov khoom siv hluav taws xob sib txawv thiab lawv cov khoom sib xyaw raws li cov xwm txheej.
• Cov zaus ntsuas, feem ntau 50Hz. Rau cov khoom xa tawm, lub zog hluav taws xob ntau ntawm qee lub tebchaws yog 60Hz.
• Rated tam sim no, muab faib ua ob hom, uas yog hais txog kev ua haujlwm tam sim no, qhov tsawg kawg yog qhov amberes, thiab qhov siab tshaj plaws tuaj yeem ncav cuag 5 ~ 7ka; Lwm tus yog qhov ntsuas tsheb npav ntsug tam sim no, uas yog hais txog kev ua haujlwm tam sim no ntawm lub nroog uas muaj me me), uas yog me dua li cov tsheb tav deb. Qhov ntsuas nyob tam sim no ntawm chav rau khoom yog feem ntau me dua, thiab cov loj dua yog 400a, 630a, thiab lwm yam.
• Kev ntsuas kev ntsuas luv luv- Circuit Rhuav tam sim no, uas yog hais txog lub peev xwm ntawm cov khoom luv tam sim no, nyob ntawm lub tshuab hloov mus nrog qhov qis- voltage switchgear.
• Rated ncov withstand cov tam sim no thiab ntsuas luv luv {{}} withstand tam sim no ntawm lub zog thiab thermal stability ntawm lub busbar.
• Kev tiv thaiv qib, uas yog hais txog kev muaj peev xwm ntawm lub tsev tiv thaiv kom tiv thaiv cov khoom txawv teb chaws los ntawm kev nkag mus rau hauv cov vaj tse thiab txav mus los tiv thaiv kom cov tsev nkag mus. Feem ntau, nws yuav tsum ncav cuag u30, thiab ntau dua qib siab muaj xws li P43, IP54, thiab lwm yam.
