LV Triple -phase CT

 

 

1. Tag Nrho Lub Sijhawm & Standard Nomenclature

Tag Nrho Lub Sijhawm: Tsawg-Voltage Peb- Theem Tam Sim No Transformer

Standard Abbreviation: LV Triple -theem CT

Cov ntsiab lus piav qhia: "Triple-theem" ​​yog qhov sib txawv tsawg dua; "Peb-theem" ​​yog lub ntsiab lus tseem ceeb ntawm kev lag luam. "LV" yog universally to taub li Low Voltage.

 

2. Core txhais

LV Peb-Phase CT yog cov cuab yeej ntsuas tam sim no tshwj xeeb tsim los rau qis-voltage, peb-theem AC hluav taws xob. Nws muaj kev nyab xeeb thiab raug ntsuas raws cov kab siab tam sim no rau tus qauv, qis- theem teeb liab haum rau cov ntsuas, relays, thiab cov cuab yeej saib xyuas.

 

3. Txhais "Low Voltage" (LV) Cov ntsiab lus

Qhov kev xaiv "LV" yog qhov tseem ceeb thiab feem ntau txhais los ntawm cov qauv hauv cheeb tsam:

IEC (International) Cov Qauv: Txog thiab suav nrog 1000 Volts AC (1 kV). Qhov no yog lub ntsiab txhais thoob ntiaj teb.

North American (ANSI/NEC) Cov ntsiab lus: Feem ntau hais txog cov tshuab txog li 600-1000 Volts.

Common Application Voltages: 400V, 480V, 690V (3-theem kab-rau-kab voltages).

 

4. Hom Tsim & Kev Tsim Kho

Vim tias qhov kev xav tau qis dua, LV CTs muaj cov yam ntxwv sib txawv:

Rwb thaiv tsev chav kawm: Feem ntau ntsuas rau 0.66 kV, 0.72 kV, lossis 1 kV systems.

 

Hom Hom:

Split-Core (Clip-On): Feem ntau nrov rau LV retrofits thiab hloov kho dua tshiab. Tso cai rau kev teeb tsa yam tsis muaj kev cuam tshuam cov conductors nyob.

Khoom-Core (Qhov txhab lossis Bar Primary): Siv nyob rau hauv cov vaj huam sib luag tshiab thiab hloov pauv (xws li MCCBs, busbars) kom raug siab dua thiab ruaj khov.

Compact, Modular Housing: Feem ntau yog ua los ntawm cov nplaim hluav taws- cov yas retardant (piv txwv li, PBT) los yog cob, tsis yog porcelain.

 

Mounting: Tsim kom yooj yim DIN-rail mounting lossis direct vaj huam sib luag mounting.

 

5. Cov ntawv thov tseem ceeb

Sub-metering & Kev Tswj Hluav Taws Xob: Ntsuas kev siv hluav taws xob hauv cov tsev lag luam, cov chaw tsim khoom, cov chaw khaws ntaub ntawv, thiab kev teeb tsa hnub ci PV.

 

• Lub Chaw Tswj Tsav Tsheb (MCCs): Muab cov lus qhia tam sim no rau kev tiv thaiv lub cev muaj zog relays thiab Variable Frequency Drives (VFDs).
• Kev saib xyuas lub zog zoo: Kev txheeb xyuas qhov sib haum xeeb, qhov tsis sib xws, thiab lub zog muaj zog hauv LV pawg thawj coj saib.
• Generator tso zis saib xyuas.
• Kev tiv thaiv: Feeder tiv thaiv, kev tiv thaiv busbar hauv LV switchgear.

 

6. Cov Ntsiab Lus Qhia Tshwj Xeeb (LV-Specific Focus)

• Rated rwb thaiv tsev Voltage (Ui): 0.72 kV lossis 1.2 kV yog cov qauv IEC rau 400/690V systems.
• Rated Primary Current: Feem ntau ntawm 50A txog 5000A, nrog 100A, 250A, 400A, 800A yog nquag heev.
• Rated Secondary Tam sim no: 5A (ib txwm siv) lossis 1A (tus qauv niaj hnub, qis dua).
• Cov chav kawm raug: 0.5, 1.0 rau metering; 5P, 10P rau kev tiv thaiv.
• Burden: Tsawg, feem ntau 2.5 VA rau 10 VA, vim yog cov ntsuas hluav taws xob niaj hnub nrog siab -impedance inputs.

 

 

Engineered rau kev ua tau zoo hauv kev xav tau hluav taws xob ib puag ncig, DIXSEN DL3N1-45 yog qhov chaw-txuag, kev sib xyaw peb-theem tam sim no transformer. Nws muab peb txoj kev ntsuas kev sib txuas rau hauv ib qho, ruaj khov- chav tsev tseem ceeb, muab cov kev daws teeb meem thiab txhim khu kev qha rau kev saib xyuas thiab kev tiv thaiv tam sim no.

 

Cov khoom tseem ceeb:

High-Kev sib xyaw ntom ntom: Muab peb tus neeg hloov pauv tam sim no rau hauv ib qho khoom siv sib koom ua ke, txo cov kev sib koom ua ke ntau dua 60% thiab tshem tawm cov kev sib tsoo thiab kev sib txuas ntawm ntau qhov sib cais.

 

DIN-Rail Mounted Efficiency: Tsim los ncaj nraim, cuab yeej-dawb installation ntawm tus qauv DIN rails, feem ntau nyob ib sab ntawm lub ntsiab Circuit Court breakers los yog feeder tiv thaiv cov cuab yeej, streamlining vaj huam sib luag layout thiab txij nkawm.

 

Extended High - Ntau yam tam sim no: Engineered rau kev thov daim ntawv thov nrog qhov dav thawj qhov ntsuas tam sim no ntawm 250A txog 600A, ua rau nws zoo tagnrho rau cov vaj huam sib luag loj, cov tshuab loj, thiab kev saib xyuas kev nkag.
