Khoom Paub meej

YSM6-12/24 unit hom SF6 RMU nrog SF6 load hloov raws li lub ntsiab hloov, rau tag nrho cov txee yog haum rau hluav taws xob automation thiab compact kuj expandable hlau kaw switchgear. Nws cov cim nyob rau hauv nws cov qauv yooj yim, hloov tau yooj yim, txhim khu kev qha interlocking thiab yooj yim installation thiab lwm yam, uas muaj peev xwm muab cov kev txaus siab rau ob qho tib si rau txawv daim ntawv thov zaus thiab cov neeg siv. Nrog rau kev txais yuav ntawm sensor technology thiab kev tiv thaiv relay mus txog rau hnub tim, ntxiv rau cov kev siv technology siab heev thiab hloov tau yooj yim los ua ke project.

C YSM6-12/24 unit hom SF6 RMU tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev lag luam tsis tu ncua. Nws tuaj yeem siv tus kheej tsim SF6- 12/24 load so hloov; Txoj kev ua haujlwm rau lub ntsiab hloov hauv lub nplhaib tseem ceeb tuaj yeem yog phau ntawv lossis hluav taws xob tsav. Thiab nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm "Four Controls" thaum sib tw nrog FTU thiab RTU.

5 qhov chaw rau chav tsev hom SF6 nplhaib lub ntsiab chav tsev:

1. hloov cubicle hloov-disconnector thiab earthing hloov nyob rau hauv ib lub thawv ntim nrog SF6 thiab txaus siab“sealed siab system "yuav tsum tau.

2. bus-bar cubicle tag nrho nyob rau hauv tib lub dav hlau kab rov tav, yog li ua rau tom qab switchboard extensions thiab kev twb kev txuas rau cov khoom uas twb muaj lawm.

3. Kev sib txuas lub cubicle tuaj yeem nkag mus rau pem hauv ntej, kev sib txuas mus rau qhov hloov qis- disconnector thiab earthing hloov terminals (IM cubicles) los yog qis fuse- tuav (PM thiab QM cubicles). Lub compartment no kuj tau nruab nrog ib qho

earthing hloov downstream los ntawm MV fuses rau cov chav tiv thaiv.

4. kev ua haujlwm mechanism, interlocking muaj cov ntsiab lus siv los ua haujlwm ntawm lub switchdisconnector thiab earthing hloov thiab actuate tus coj.

indications (zoo so).

5. Tsawg voltage cubicle (sab sauv & qis enclosure qauv) installation ntawm a

Lub davhlau ya nyob twg thaiv (yog tias xaiv lub cev muaj zog), LV fuses thiab cov khoom siv sib txuas sib txuas. Yog tias xav tau chaw ntxiv, ib qho thaiv ntxiv tuaj yeem muab ntxiv rau saum

kub.

6. yeem hloov cubicles (IM) kuj tuaj yeem haum nrog: tswj motorisation;

surge arrestors.

Peb-theem rotary tiv tauj yog ntsia rau hauv lub chamber roj uas muaj SF6 roj thiab cov txheeb ze siab yog 0.4bars. Nws muaj kev ua haujlwm zoo heev nrog kev nyab xeeb thiab kev ntseeg tau.

● Tightness:

Cov huab cua chamber yog ntim nrog SF6 roj, uas ua tau raws li tus qauv yuav tsum tau ntawm "kaw siab system", thiab sealing kev ua tau zoo tau soj ntsuam thiab

tshuaj xyuas hauv lub hoobkas.

● Kev Nyab Xeeb Kev Ua Haujlwm:

1. Qhov hloov pauv muaj peb txoj haujlwm ntawm "kaw", "qhib" thiab "grounded", thiab muaj

xauv muaj nuj nqi los tiv thaiv kev ua haujlwm tsis raug. Kev sib cuag yog tsav los tig los ntawm

lub caij nplooj ntoos hlav zog cia mechanism, uas tsis cuam tshuam los ntawm tib neeg kev ua haujlwm yam.

2. Muaj "tawg" thiab kev sib cais ua haujlwm.

3. Lub luv luv-circuit ua lub peev xwm ntawm SF6 grounding hloov ua tau raws li tus qauv yuav tsum tau ua.

4. Thaum muaj kev sib tsoo, lub siab poob qis tom qab lub overpressured SF6 gas tawg los ntawm kev nyab xeeb diaphragm, thiab cov roj yuav ncaj qha mus rau hauv qab ntawm lub txee rau kev nyab xeeb.

Breaking Principple:

SF6 roj muaj qhov zoo tshaj plaws arc extinguishing kev ua tau zoo. Thaum qhib qhov hloov pauv, qhov txheeb ze txav ntawm lub arc thiab cov pa roj yuav tua cov arc. Thaum cov kev txav mus los thiab zoo li qub tau sib cais, lub arc tshwm nyob rau hauv electromagnetic teb generated los ntawm cov hlau nplaum ruaj khov, thiab cov arc yog

elongated thiab extinguished thaum tam sim no hla xoom los ntawm SF6 roj. Qhov kev ncua deb ntawm kev txav mus los thiab kev sib cuag zoo li qub yog txaus los tiv thaiv qhov rov qab overvoltage. Lub kaw lus yooj yim thiab txhim khu kev qha, nrog kev sib cuag tsawg tsawg thiab lub neej hluav taws xob ntev.

● Switchgear xwm txheej qhia:

Haum ncaj qha mus rau tus tsav ncej, cov no muab ib tug defi nite qhia txog kev sib cuag 's txoj hauj lwm. (Cov ntawv ntxiv A ntawm tus qauv IEC 62271-102).

● Ua haujlwm lever:

Qhov no yog tsim los nrog cov khoom siv los tiv thaiv refl ex uas nres txhua qhov kev sim rov qhib lub cuab yeej tam sim tom qab kaw qhov hloov pauv lossis lub ntiaj teb disconnector.

● Xauv ntaus ntawv:

Nruab nrab ntawm ib thiab peb lub padlocks pab kom cov hauv qab no yuav tsum tau xauv:

● nkag mus rau qhov hloov pauv ntawm qhov hloov pauv lossis lub tshuab hluav taws xob hluav taws xob

● nkag mus rau lub hloov ncej ntawm lub earthing disconnector

● kev khiav hauj lwm ntawm qhov qhib tso lub laub-khawm. ● Yooj yim thiab siv zog hloov pauv

Mechanical thiab hluav taws xob tswj yog ib sab ntawm sab pem hauv ntej fascia, ntawm ib lub vaj huam sib luag

suav nrog cov schematic daim duab qhia txog cov xwm txheej ntawm lub cuab yeej (kaw, qhib, earthed):

● Kaw:

tus tsav ncej yog ua los ntawm ib tug ceev acting mechanism, ywj siab ntawm tus neeg teb xov tooj. Tsis muaj lub zog khaws cia hauv qhov hloov pauv, sib nrug ntawm thaum hloov

kev ua haujlwm tau tshwm sim.

Rau kev sib txuas ua ke fuses, qhib mechanism yog armed tib lub sij hawm thaum cov neeg raug kaw.

● Qhib:

qhov hloov pauv tau qhib siv tib lub tshuab ua haujlwm nrawm, ua haujlwm nyob rau hauv qhov kev coj ua.

Rau kev sib txuas ua ke fuses chav tsev, qhib yog tswj los ntawm:

● lub laub khawm

● kev txhaum.

● Earthing:

ib tug tshwj xeeb c tswj ncej enables qhib los yog kaw ntawm lub earthing hu. Kev nkag mus rau cov ncej no yog thaiv los ntawm lub hau npog uas tuaj yeem thim rov qab yog tias qhov hloov pauv

qhib tab sis qhov twg tseem kaw hauv qhov chaw yog tias nws raug kaw.

Voltage muaj qhov taw qhia

Cov cuab yeej no tau koom ua ke VPIS (Voltage Presence Indicating System) hom teeb, ua raws li IEC tus qauv 61958, ua kom muaj qhov muaj (lossis tsis muaj) ntawm qhov hluav taws xob los kuaj xyuas cov cables.

Insensitivity rau ib puag ncig

● Lub kaw lus kaw sab hauv, muaj cov khoom siv ntawm LBSkit

(switch, earthing disconnector). Nws tau sau nrog SF6 raws li cov lus pom zoo hauv IEC 62271-200 rau "lub siab kaw

systems ”.

Sealing systematically kuaj nyob rau hauv lub Hoobkas.

● Cov khoom yog tsim los kom tau txais cov khoom siv hluav taws xob zoo tshaj plaws.
