Qhov sib txawv ntawm Switchgear Txee thiab Distribution Txee

Qhov tseem ceeb sib txawv ntawmswitchgear txeethiabkev faib khoom txeedag hauv lawvfunctional positioning thiab voltage theem.Switchgear txee ua haujlwm rau hubstswj thiab tiv thaiv, tsom rau "circuit breaking, kaw thiab rho tawm"; Distribution cabinets pab raws li lub hwj chim faib & muab terminals, tsom rau lub hwj chim branching thiab kawg - neeg siv hluav taws xob tiv thaiv.

 

Dimension	Switchgear Txee	Kev faib khoom txee
Core Function	Tswj kev sib txuas hauv Circuit Court & disconnection, cais qhov yuam kev, xyuas kom muaj kev ruaj ntseg system; ua raws li lub hauv paus tseem ceeb ntawm lub zog thiab cov khoom siv hluav taws xob tseem ceeb	Faib fais fab mus rau theem nrab circuits thiab davhlau ya nyob twg loads, thiab muab kev tiv thaiv yooj yim tiv thaiv overload, luv Circuit Court thiab lwm yam txhaum.
Qib voltage	Feem ntau cov high voltage (3.6–40.5kV), kuj muaj nyob rau hauv tsawg-voltage	Feem ntau tsis tshua muaj hluav taws xob (tsawg dua lossis sib npaug rau 1000V)
Tej Cheebtsam	Circuit Court breaker, disconnector, earthing hloov, transformer, relay tiv thaiv ntaus ntawv, feem ntau hlau enclosed qauv	Circuit Court breaker, fuse, contactor, seev; txuas ntawm tooj liab tuav los yog xov hlau, pem teb - sawv los yog phab ntsa- mounted
Daim ntawv thov Scenario	Substations, chav faib hluav taws xob, cov chaw tsim hluav taws xob	Factory Rhiav, cov tsev lag luam, cov tsev nyob thiab lwm qhov chaw siv hluav taws xob
Loj & Kev Tiv Thaiv	Loj loj (qhov siab: 1.8-2.2m +), qib tiv thaiv siab (feem ntau IP40 thiab siab dua)	Saj zawg zog loj (cov phab ntsa compact{0}}mounted hom muaj), Medium tiv thaiv qib (IP30–IP54 feem ntau)

 

Kev soj ntsuam ntxaws txog qhov sib txawv tseem ceeb

 

Functional Positioning:Lub txee switchgear yog "lub ntsiab hloov" ntawm lub zog hluav taws xob. Nws yog lub luag haujlwm rautxuas / txiav tawm siab -voltage thiab tseem ceeb circuits, cais cov cuab yeej rau kev tu, thiab txiav tawm faulty circuits sai sai los tiv thaiv kev sib tsoo nce.A lub txee faib ua haujlwm ua "lub zog faib hluav taws xob", uas faib lub zog los ntawm cov khoom siv hluav taws xob sab saud mus rau txhua ceg hauv Circuit Court, tsom mus rauTerminal fais fab mov thiab kev tiv thaiv hluav taws xob yooj yim.

 

Structure & Cheebtsam:Switchgear txee muaj kev sib koom ua ke siab nrog kev tsim sab hauv (busbar compartment, Circuit Court breaker compartment, thiab lwm yam). Cov khoom siv sab hauv yog tsim los tiv taus siab tam sim no thiab luv luv -circuit tam sim no, nruab nrog kev tiv thaiv kev ua haujlwm.Distribution txee txais yuav cov qauv yooj yim nrog cov khoom siv modular, ua kom yooj yim nthuav dav thiab niaj hnub tu.

 

 

Daim ntawv thov Scenario:Switchgear txee yog siv raucore nodes ntawm lub hwj chim systems, xws li lub ntsiab transformer nkag kab nyob rau hauv substations thiab lub ntsiab fais fab kev noj ntawm loj factories.Distribution txee yog siv rauterminal fais fab mov, suav nrog cov khoom siv hluav taws xob hauv chav ua haujlwm, chav faib hauv pem teb, cov thawv faib khoom hauv tsev, thiab lwm yam.

 

Cov ntsiab lus tsis meej pem

Hauv kev siv txhua hnub, lo lus "distribution cabinet" ua lub npe dav dav rau txhua lub hwj huam xa khoom enclosures.Los ntawm kev lag luam kev lag luam, cov khoom siv hluav taws xob muaj hluav taws xob sib xyaw ua ke yog hu ua switchgear, thaum cov khoom siv hluav taws xob qis hluav taws xob tau txhais tau tias yog cov khoom siv hluav taws xob tsawg, cov khoom siv hluav taws xob tsawg, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob feem ntau yog cov khoom siv hluav taws xob tsawg, txij li cov khoom siv hluav taws xob tsawg tsawg.

 

Ib - kab lus Summary

Cov txee Switchgear yog lub luag haujlwm rau kev tswj xyuas hluav taws xob thiab kev nyab xeeb ntawm lub cev, thaum cov khoom xa tawm ua haujlwm rau kev faib hluav taws xob thiab cov khoom siv hluav taws xob.
