Vim li cas lub tshuab hluav taws xob hu ua cov txheej txheem tiav, thiab cov khoom dab tsi nws muaj? - Blog

saib tag

Lub switchgear yog hu ua "tag nrho" vim tias nws tsis yog ib qho khoom siv nkaus xwb, tab sis yog qhov ua tiav thiab sib koom ua ke ntawm ntau yam khoom siv hluav taws xob, cov khoom sib txuas, cov khoom sib txuas, cov khoom siv hluav taws xob, kev txhawb nqa, thiab cov ntaub thaiv npog.

Cov khoom tseem ceeb ntawm switchgear

Lub sij hawm "txuas" nyob rau hauv switchgear txee feem ntau yog hais txog ib chav ua haujlwm. Ib qho chaw ua tiav lossis chav faib khoom yog tsim los ntawm ntau lub txee nrog cov haujlwm sib txawv ua ke. Lawv tuaj yeem muab faib ua pawg hauv qab no:

1. Cov Khoom Muag Khoom

Muaj nuj nqi: Lub zog hluav taws xob nkag mus rau lub zog hluav taws xob, feem ntau txuas nrog lub chaw nres tsheb sab saud lossis hloov pauv. Nws yog "lub ntsiab hloov" ntawm tag nrho cov system.

2. Outgoing Line txee (Feeder txee)

Muaj nuj nqi: Faib hluav taws xob hluav taws xob rau ntau lub zog hauv qab-cov khoom siv (xws li cov tshuab hloov pauv hauv cov chaw ua haujlwm lossis hauv pem teb, lub thawv xa khoom, thiab lwm yam).

Cov cuab yeej tseem ceeb: Circuit Court breakers (los yog load switches + fuse ob peb), tam sim no transformers, tiv thaiv pab kiag li lawm, thiab lwm yam. Ib qho system feem ntau muaj ntau cov kab tawm.

3. Bus Tie Txee

Muaj nuj nqi: Txuas ob qhov kev ywj pheej busbar. Thaum ib txoj kab hluav taws xob tuaj tsis tau, ob qhov chaw nres tsheb tuaj yeem ua rau tib lub zog los ntawm lwm qhov hluav taws xob los ntawm lub tsheb npav khi, txhim kho cov khoom siv hluav taws xob.

Cov Khoom Tseem Ceeb: Bus khi Circuit Court breaker thiab nws cov khoom tiv thaiv.

4. Metering txee

Muaj nuj nqi: Tshwj xeeb yog siv rau kev ntsuas hluav taws xob, rau cov chaw muab hluav taws xob los daws cov nqi hluav taws xob. Lub txee feem ntau yog kaw; cov neeg siv yuav tsum tsis txhob ua nws arbitrarily.

Cov Khoom Tseem Ceeb: High-precision voltage transformers, tam sim no transformers, thiab lub zog ntsuas.

5. PT txee (Voltage Transformer Txee)

Muaj nuj nqi: Muab ntsuas qhov ntsuas hluav taws xob thiab kev tiv thaiv hluav taws xob hluav taws xob, thiab muab AC220V lub zog rau lub zog ua haujlwm. Nws cov busbars sab hauv yuav tsum tau tiv thaiv los ntawm siab -voltage fuses.

6. Cov Txiaj Ntsig cais

Muaj nuj nqi: Muaj ib qho kev hloov pauv kom cais cov busbar lossis cov khoom siv, tsim kom pom thiab muaj kev nyab xeeb hluav taws xob cuam tshuam rau kev saib xyuas yooj yim.

Nco tseg: cais cov keyboards tsis muaj arc-extinguishing peev xwm; kev ua haujlwm nyob rau hauv load yog nruj me ntsis txwv.

7. Capacitor Compensation Txee

Function: Siv los txhim kho lub zog zoo thiab ua kom lub zog muaj zog. Nws cia li hloov lub hwj chim capacitor txhab nyiaj rau offset reactive zog generated los ntawm inductive loads (xws li motors).

Cov Khoom Siv Tseem Ceeb: Lub hwj chim capacitors, reactors, switching switches (contactors los yog thyristors), reactive fais fab them nyiaj xws li.

lwm qhov chaw

Ntxiv nrog rau cov kab nkag, ntsuas, PT, thiab cov kab hluav taws xob tawm tau hais los saum no, cov khoom siv hluav taws xob kuj tseem muaj xws li cov khoom siv tsheb thauj mus los, cov tsheb npav khi, thiab lwm yam. Busbar cov khoom siv feem ntau yog siv los txuas switchgear hauv cov bays sib txawv kom ua tiav cov khoom siv hluav taws xob; tsheb npav khi cov khoom siv los txuas cov ntu sib txawv ntawm cov busbars sib txawv kom ntseeg tau tias muaj hluav taws xob txuas ntxiv ntawm cov busbars thiab txhim kho cov khoom siv hluav taws xob. Tsis tas li ntawd, hauv qee qhov chaw nres tsheb loj lossis cov tshuab hluav taws xob nyuaj, kuj tseem tuaj yeem hloov pauv nrog cov haujlwm tshwj xeeb xws li cov khoom seem hauv lub thawv thiab cov khoom siv hluav taws xob.

KYN28-12 sab hauv tsev armored hlau-kab hloov khoom siv(tom qab no hu ua KYN28-12 switchgear) yog tsim rau peb -theem AC 50HZ, 7.2 ~ 17.5kV ib lub tsheb npav thiab ib lub tsheb npav ib ntus hluav taws xob, nrog kev ua haujlwm zoo "tsib pov thawj". Qhov tshem tau ntawm lub txee switchgear tuaj yeem nruab nrog lub tshuab nqus tsev nqus hluav taws xob los yog lub tshuab nqus tsev contactor, cais tawm trolley, PT trolley thiab lwm yam khoom.
