Yuav ua li cas lub txee Switchgear ua haujlwm - Ib kauj ruam los ntawm kauj ruam
Kev nkag siab txog lub zog ntws hauv lub txee ua rau nws yooj yim dua rau kev qhia, nruab thiab tswj. Hauv cov hlau ib txwm-clad switchgear txee, lub zog hluav taws xob ua raws li txoj hauv kev no:
① Txais Cable / Transformer Feeder
Lub zog nkag mus rau hauv lub txee
②Main Hloov / Incoming Breaker
Tiv thaiv tag nrho lub txee
③Main Busbar
Faib zog rau tag nrho cov feeders
④ Outgoing Breaker / LBS / Fuse
Txhua Circuit Court tiv thaiv tus kheej
⑤CT / VT + Relay
Ntsuas thiab saib xyuas txhua lub voj voog
⑥ Thauj khoom
Factory, tsev, substation lossis PV cog
Cov khoom xa tuaj nkag mus rau hauv lub cable compartment thiab txuas mus rau lublub ntsiab nkag breaker.
Lub breaker feeds lublub ntsiab busbar, uas khiav kab rov tav los ntawm lub busbar compartment thiab khoom siv txhua qhov tawm mus.
Txhua qhov khoom tawm tawm yog tiv thaiv los ntawm nws tus kheej lub tshuab hluav taws xob, fuse hloov disconnector lossis thauj khoom - tawg hloov.
Tam sim no transformers ntawm txhua tus feeder kauj ruam tam sim no mus rau kev tiv thaiv relay, uas tsis tu ncua sib piv cov nqi ntsuas tiv thaiv qhov chaw tiv thaiv.
Thaum muaj kev txhaum tshwm sim - overload, luv Circuit Court lossis lub ntiaj teb txhaum - lub relay mus ncig lub breaker nyob rau hauv milliseconds, cais tsuas yog lub faulty feeder thaum lub sij hawm seem ntawm lub system tseem khiav.
Surge tiv thaiv cov cuab yeejdivert xob laim thiab hloov surges rau lub ntiaj teb, thaum lubearthing systemmuab txoj hauv kev nyab xeeb rau txhua qhov kev txhaum tam sim no.
Qhov no yog vim li cas lub txee hloov pauv tau piav qhia tias yog "qhov nruab nrab ntawm lub paj hlwb" ntawm lub zog hluav taws xob: txhua txoj haujlwm - nqa, tswj, tiv thaiv, ntsuas, cais tawm - tshwm sim hauv ib qho kev sib koom ua ke, thiab txhua yam yog nyob ntawm kev ua haujlwm raug ntawm lwm tus.

Kauj Ruam 2 - Sib phim qhov chaw teeb tsa
Sab hauv tsev tswj ib puag ncig → IP4X txaus. Sab nraum zoov / ntug hiav txwv dej / plua plav → IP54 nrog tiv thaiv - cua sov cua sov, SS304 enclosure xaiv, thiab UV- cov xim resistant.
Kauj ruam 3 - Xam luv-Circuit Duty
Paub meej tias luv luv - lub peev xwm ntawm qhov hluav taws xob ntawm qhov chaw teeb tsa (feem ntau 25 / 31.5 / 40 kA). Lub switchgear txee tawg & luv-lub sij hawm tiv thaiv kev ntsuam xyuas yuav tsum muaj ntau dua los yog sib npaug ntawm tus nqi no.
Kauj Ruam 4 - Txhais daim duab kab ib kab
Tus naj npawb ntawm feeders, CT ratios, kev tiv thaiv relay qauv (overcurrent / nrug / sib txawv), metering, kev sib txuas lus raws tu qauv (Modbus / IEC 61850). Xa koj SLD rau peb → peb yuav xa rov qab rau lub thawv hloov pauv hloov kho BOM thiab cov npe nqi hauv 24 teev.
Installation & Maintenance ntawm Switchgear txee
Kev lag luam kev paub qhia tau hais tias kev teeb tsa tsis zoo tuaj yeem ua rau cov nqi khiav lag luam nce mus txog30%, thiab roughly50% ntawm cov khoom siv tsis ua haujlwmtuaj yeem taug qab rov qab mus rau kev saib xyuas tsis txaus. Lub txee switchgear yog qhov ntev - lub neej khoom vaj khoom tsev (20+ xyoo) - yuav ua li cas nws tau nruab thiab kev pabcuam txiav txim siab seb nws mus txog lub neej ntawd lossis ua tsis tiav thaum ntxov.

10. Yuav ua li cas kuv thiaj li thov tau lub switchgear txee quotation?
Xa peb koj daim duab kab ib kab (SLD), kev qhia tshwj xeeb, kom muaj nuj nqis, thiab qhov chaw nres nkoj. Peb tus kws tshaj lij kev muag khoom yuav teb nrog cov lus hloov pauv hloov pauv tag nrho - suav nrog nqi tsev, lub sijhawm ua haujlwm, ntim khoom, kev kwv yees kev thauj khoom hiav txwv, thiab cov nqe lus them nqi - hauv 24 teev.
11. Dab tsi yog cov khoom tseem ceeb hauv lub txee switchgear?
Ib tug ua tiav switchgear txee muaj peb pawg:
(1) cov khoom siv hluav taws xob tseem ceeb - Circuit Court breaker (VCB / MCCB / ACB), disconnector / isolator, tooj liab busbar, tam sim no & voltage transformers, auxiliary transformer;
(2) tiv thaiv & tswj cov cuab yeej - tiv thaiv relay, contactor, interlocking system, meters & ntsuas, surge tiv thaiv ntaus ntawv (SPD), fuse hloov disconnector;
(3) Cov yam ntxwv ntawm cov khoom siv - enclosure, insulators & busbar txhawb nqa, qhov cua & cua txias, cable terminals, earthing system. Saib cov ntsiab lus tseem ceeb saum toj no rau tag nrho cov lus nrog cov lus qhia tshwj xeeb.
12. Dab tsi yog qhov sib txawv ntawm lub tshuab hluav taws xob thiab lub disconnector (isolator) hauv lub txee?
Lub Circuit Court breaker cia li cuam tshuam tam sim no ntawm overload lossis luv luv Circuit Court thiab tseem tuaj yeem ua manually - nws tiv thaiv Circuit Court nyob rau hauv load. Lub disconnector (isolator) tsuas yog tsim kom pom, muaj kev nyab xeeb so rau kev saib xyuas thiabua tsis taucuam tshuam load tam sim no; nws yuav tsum tau ua tsuas yog tom qab lub breaker tau qhib. Ob leeg yog interlocked nyob rau hauv peb lub txee kom lawv tsis tuaj yeem ua haujlwm tsis raug.
13. Dab tsi yog qhov txawv ntawm lub txee switchgear thiab lub txee faib khoom?
Lub txee switchgear zaum ntawm qhov system theem - nws tau txais lub zog los ntawm lub tshuab hluav taws xob / khoom xa tuaj, xa mus rau circuits, thiab tiv thaiv lub network (12 - 40.5 kV HV lossis 380 - 660 V LV). Nws yog loj thiab ntsia hauv substations / switchgear chav. Lub txee faib khoom (lub thawv) yog cov cuab yeej siv kawg: nws siv lub zog los ntawm qib siab thiab pub cov khoom thauj ze tshaj plaws nrog kev tiv thaiv cheeb tsam. Nws yog me dua, feem ntau phab ntsa -mounted. GNEE muab ob qho tib si, tsim kho kom haum ib leeg - saib cov lus hais saum toj no.
14. Ntev npaum li cas yuav tsum tau kuaj xyuas thiab tswj xyuas lub tshuab hloov pauv?
Raws li cov lus qhia: LV switchgear txee - pom thiab thermal tshuaj xyuas peb lub hlis twg; MV / HV cov khoom siv - txhua 6 lub hlis rau kev ua haujlwm ntawm cov khoom siv kho tshuab thiab kev kuaj xyuas relay, txhua xyoo rau kev txhaj tshuaj thiab kev ntsuas rwb thaiv tsev; sab nraum zoov / ntug hiav txwv dej - kev kuaj pom txhua hli ntxiv rau kev kuaj xyuas tom qab txhua qhov cua daj cua dub. Ib daim ntawv teev kev saib xyuas tag nrho yog nyob rau hauv ntu Installation & Maintenance saum toj no.
15. Cov khoom ntawm kuv lub txee switchgear puas tuaj yeem hloov kho lossis hloov tom qab?
Yog lawm. Peb cov khoom siv hluav taws xob siv cov khoom siv hluav taws xob, cov qauv ntsuas: lub tshuab nqus tsev vacuum yog nyob rau ntawm lub tsheb tshem tawm (KYN / MNS series), yog li nws tuaj yeem hloov pauv yam tsis muaj kev cuam tshuam rau lub busbar; relays, meters, SPDs thiab CTs yog ntsaws- thiab tuaj yeem hloov kho rau cov qauv ntse nrog Modbus / IEC 61850 kev sib txuas lus txhua lub sijhawm. Peb kuj muab cov kev daws teeb meem rov qab kho dua tshiab rau cov khoom uas twb muaj lawm los ntawm lwm lub npe.
16. Cov ntaub ntawv kaw lus twg thiab qhov ntsuas IP muaj nyob?
Standard enclosure yog 1.5 - 2.0 mm txias -kub galvanized steel nrog epoxy hmoov txheej, RAL 7035, IP30 - IP54. Cov kev xaiv kho dua tshiab muaj xws li stainless hlau SS304 / SS316 rau cov ntug hiav txwv dej, khoom noj khoom haus, tshuaj lom neeg thiab kev siv sab nrauv; IP65 / IP66 gasketed sab nraum zoov cov ntaub ntawv; siab-UV sab nraum zoov- qib xim; thiab tiv thaiv- cua sov cua sov rau huab cua ntub. Cov ntsiab lus tag nrho yog nyob rau hauv Kev Tsim Khoom & Customization seem.
17. Vim li cas lub surge tiv thaiv ntaus ntawv (SPD) yog ib qho tseem ceeb nyob rau hauv lub switchgear txee?
xob laim thiab hloov pauv yog qhov ua rau muaj kev puas tsuaj rau cov relays, meters, daim npav sib txuas lus thiab lwm yam khoom siv hluav taws xob hauv lub txee. Ib qho SPD hloov pauv qhov nce mus rau lub ntiaj teb hauv microseconds ua ntej nws mus txog cov cuab yeej no. Rau cov ntse -daim phiaj, hnub ci thiab cov ntaub ntawv- cov haujlwm hauv nruab nrab peb haum rau Hom 1 + Hom 2 SPDs ntawm txoj haujlwm tuaj raws li tus qauv - qhov no yog kev pov hwm pheej yig piv nrog kev tiv thaiv tsis ua haujlwm lossis kev cog qoob loo.
