Khoom taw qhia

Nyob rau hauv lub zog hluav taws xob, qhov nruab nrab voltage switchgear (Medium Voltage switchgear) yog qhov tseem ceeb hub txuas high-voltage kis tau tus mob thiab qis-voltage fais fab kev faib, thiab feem ntau yog lub luag hauj lwm rau kev faib thiab tswj cov hluav taws xob hluav taws xob nyob rau hauv voltage range ntawm 3kV mus rau 40.5kV.Yog hais tias lub transformer yog piv rau lub plawv, lub "joint" switchgear. Nws lub luag haujlwm tseem ceeb yog faib cov Circuit Court thaum lub sijhawm ua haujlwm ib txwm muaj, thiab thaum lub sijhawm luv luv lossis overload, txiav tawm qhov txhaum tam sim no hauv milliseconds los tiv thaiv kev nyab xeeb ntawm cov khoom kim thiab kab.

Kev txheeb xyuas luv luv ntawm txoj haujlwm ua haujlwm

Qhov kev ua haujlwm ntawm qhov nruab nrab voltage switchgear tuaj yeem raug suav hais tias yog peb txoj haujlwm "Switching, tiv thaiv, thiab kev sib cais":

Hloov

Los ntawm Circuit Court breakers los yog load switches, lub Circuit Court yog qhib los yog kaw nyob rau hauv ib txwm muaj los yog txhaum tej yam kev mob kom paub qhov kev faib thiab tswj ntawm hluav taws xob lub zog.

Kev tiv thaiv

Thaum lub kaw lus yog overloaded, luv luv, los yog hauv av, tam sim no transformer (CT) thiab voltage transformer (PT) xa cov teeb liab mus rau lub relay tiv thaiv ntaus ntawv, uas sai sai qhia lub Circuit Court breaker mus txawv tebchaws thiab cais thaj tsam txhaum.

Muab cais nyob ib leeg

Los ntawm kev sib cais hloov lossis hloov hauv av, cov khoom siv yuav raug kho yog cais tawm ntawm qhov chaw nyob thiab hauv av kom ntseeg tau tias tus kheej muaj kev nyab xeeb ntawm kev ua haujlwm thiab cov neeg ua haujlwm tu.

Khoom zoo

Ua ke nrog Kechang Electric cov kev koom ua ke hauv kev ua haujlwm siab -voltage / nruab nrab-voltage tiav cov cuab yeej, peb cov khoom nruab nrab-voltage switchgear cov khoom cuam tshuam txog cov txiaj ntsig hauv qab no hauv kev tsim:

Sturdy armored qauv

Lub txee lub cev yog ua los ntawm siab- zoo aluminium-zinc phaj lossis txias- dov steel phaj ua tiav thiab tsim los ntawm cov cuab yeej CNC, thiab cov khoom siv hlau yog siv los cais cov khoom sib cais. Qhov kev tsim "hlau armor" no tuaj yeem tiv thaiv kev sib kis ntawm faulty arcs thiab xyuas kom meej tias txawm tias ib chav tsev tsis ua haujlwm, nws yuav tsis kis mus rau lwm lub voj voog.

Zoo meej "tsib- pov thawj" interlocking

Lub hauv paus ntawm kev nyab xeeb yog tiv thaiv tib neeg kev ua haujlwm tsis zoo. Kechang switchgear yog nruab nrog cov cuab yeej siv hluav taws xob nruj thiab cov khoom siv hluav taws xob sib cuam tshuam, uas paub txog cov haujlwm "tsib- pov thawj": txhawm rau tiv thaiv kev sib cais ntawm kev rub tawm, tiv thaiv lub Circuit Court breaker los ntawm kev ua yuam kev, tiv thaiv lub hauv av xaim los ntawm kev dai, tiv thaiv cov av xaim los ntawm kev xa hluav taws xob, tiv thaiv kom tsis txhob muaj kev cuam tshuam los ntawm kev ua haujlwm ntawm lub cev, thiab tshem tawm cov kev ua haujlwm ntawm lub cev.

Yooj yim thiab txhim khu kev qha daws teeb meem

Cov khoom lag luam npog ntau yam kev daws teeb meem los ntawm kev rwb thaiv tsev huab cua mus rau ib puag ncig tus phooj ywg roj rwb thaiv tsev (C-GIS). Piv txwv li, peb lub txee inflatable siv lub stainless hlau cua tank los kaw tag nrho cov siab -voltage nyob qhov chaw, uas tsis cuam tshuam los ntawm ib puag ncig sab nraud. Nws yog tshwj xeeb tshaj yog haum rau hnyav ua hauj lwm tej yam kev mob xws li underground thiab toj siab, thiab nws yog ntau compact thiab chaw-txuag.

Durable thiab ntse

Ua raws li lub tswv yim ntawm "ua haujlwm ruaj khov thiab txhim khu kev qha", cov khoom tseem ceeb yog ua los ntawm cov ntaub ntawv tshwj xeeb siab - thiab qhov zoo yog tswj los ntawm cov txheej txheem nruj heev. Nyob rau tib lub sijhawm, cov khoom lag luam txhawb kev sib koom ua ke cov kev soj ntsuam cov ntse ntse, uas tuaj yeem sau cov ntaub ntawv xws li qhov kub thiab txias, qhov tso tawm hauv zos, thiab roj ceev hauv lub sijhawm, thiab muab cov ntaub ntawv hauv paus rau kev saib xyuas tsis tu ncua thiab raws li txoj cai.

Hom Daim Ntawv Thov Scenarios

Kev faib tawm hauv nroog thiab kev lag luam complex:Raws li cov khoom siv tseem ceeb ntawm 10kV / 35kV chav faib khoom, nws yog lub luag haujlwm rau kev txais tos, kev faib tawm thiab kev tiv thaiv hluav taws xob hluav taws xob.

Muaj chaw ua si thiab loj - cov chaw ua haujlwm thiab cov mines:muab kev tswj fais fab kev ntseeg siab thiab luv luv - tiv thaiv Circuit Court rau loj - muaj peev xwm thauj khoom xws li cov kab ntau lawm, kiv cua, chaw nres tsheb, thiab lwm yam.

Tshiab zog teb chaw nres tsheb:nws yog siv rau lub collector Circuit Court ntawm cua ua liaj ua teb thiab photovoltaic fais fab nroj tsuag kom paub multi-channel convergence thiab daim phiaj{1}} txuas tswj.

Tsheb thauj mus los hub:Siv nyob rau hauv lub hwj chim mov system ntawm subways, tshav dav hlau, thiab railway traction chaw nres tsheb, nws muaj tsis tshua muaj siab xav tau rau lub continuation ntawm lub hwj chim mov.

Data centers thiab tsev kho mob:muab ob lub- voj lossis ntau- lub voj voog fais fab rau thawj qhov kev thauj khoom kom ntseeg tau tias kev ua haujlwm tsis cuam tshuam ntawm cov khoom tseem ceeb.
