Hauv kev ntsuas hluav taws xob, lub tshuab hluav taws xob tam sim no (CT) yog cov khoom siv hluav taws xob siv los ntsuas qhov tam sim no. Nws hloov cov dej ntws loj rau hauv qhov sib npaug me me, yooj yim rau kev siv xws li ntsuas tam sim no, saib xyuas, tiv thaiv, thiab tswj.
Tam sim no, hauv cov kev daws teeb meem tseem ceeb, faib-cov tub ntxhais CTs thiab cov khoom ruaj khov-cov tub ntxhais CTs txhua tus tau qhia meej meej txog thaj tsam ntawm daim ntawv thov. Kev xaiv ntawm tam sim no transformer ncaj qha cuam tshuam rau metering raug, installation nqi, thiab ntev - lub sij hawm cia siab rau.
Cov qauv sib txawv thiab cov qauv kev ua haujlwm
Qhib - hom CT (Tam sim no Transformer)
- Cov yam ntxwv zoo
Cov tub ntxhais tau txais kev sib cais tsim, nrog lub pob khawm lossis snap- haum rau ntawm ib sab, tso cai rau nws qhib thiab kaw rau tus neeg xyuas pib yam tsis muaj kev cuam tshuam lub voj voog.
- Installation nta
Ncaj nraim qhwv ib ncig ntawm cov neeg ua haujlwm nyob, txhawb kev ua haujlwm nyob, haum rau kev txhim kho cov kab uas twb muaj lawm.
Kaw - voj CT (Tam sim no Transformer)
- Cov yam ntxwv zoo
Cov tub ntxhais yog lub nplhaib ua tiav, thiab tus neeg xyuas pib yuav tsum dhau los ntawm cov tub ntxhais los tsim ib lub voj voog kaw sib nqus.
- Installation yam ntxwv
Yuav tsum muaj hluav taws xob hluav taws xob rau kev teeb tsa thiab tshem tawm busbar; haum rau kev tsim kho tshiab lossis cov xwm txheej uas muaj hluav taws xob raug tso cai.
Qhov sib txawv ntawm lub cev tseem ceeb yog qhov qhib sib nqus hluav taws xob muaj qhov sib txawv ntawm huab cua, uas ua rau kom muaj qhov sib nqus tsis txaus siab; Lub kaw magnetic Circuit Court yog tas mus li, thiab lub magnetic reluctance yog minimized.
Kev sib piv tseem ceeb
Qhov tseeb thiab ruaj khov
| Index | Split -Core CT | Khoom -core CT |
|---|---|---|
| Yam raug | 1% -2% (Qee lub tuam txhab tuaj yeem ncav cuag Chav Kawm 0.5) | 0.2% -0.5% (Standard industrial qib) |
| Ntev -lub sij hawm Drift | Tsawg dua lossis sib npaug li ± 1% / xyoo (Kev cuam tshuam los ntawm kev co thiab kev laus) | Tsawg dua los yog sib npaug rau ± 0.2% / xyoo (Cov qauv kaw tag nrho) |
| Muaj peev xwm tiv thaiv - cuam tshuam | Tsis muaj zog (Sab nraud magnetic teb yooj yim nkag mus rau hauv huab cua sib txawv) | Muaj zog (Closed magnetic circuit shields interference) |
Xaus: Kaw - voj metering muaj qhov zoo dua tsis tuaj yeem hloov pauv hauv qhov tseeb hauv kev ntsuas qhov xwm txheej (xws li kev them nqi hluav taws xob).
Installation thiab Economy
| Dimension | Split -Core CT | Khoom -core CT |
|---|---|---|
| Lub Sijhawm Txhim Kho | 5-10 feeb/unit (nyob-kab ua haujlwm) | Ntau tshaj lossis sib npaug li 30 feeb / chav tsev (yuav tsum tau hluav taws xob hluav taws xob) |
| Tus Nqi Ua Haujlwm | Txo los ntawm 60% (tsis muaj xov hlau disassembly, tsis muaj hluav taws xob poob) | Siab dua (yuav tsum muaj kev sib koom ua haujlwm hluav taws xob, kev sib txuas ua ke) |
| Tus nqi kho vajtse | Siab dua (cov qauv complexity +20% ~ 30%) |
Lower (standardized ntau lawm) |
Kev nyab xeeb thiab ib puag ncig adaptability
Kev pheej hmoo cuam tshuam nrog qhib- hom tshuab:
Plua plav thiab ya raws tuaj yeem yooj yim khaws cia hauv qhov sib txawv ntawm huab cua, feem ntau ua rau qhov ntsuas IP tsawg dua lossis sib npaug ntawm IP54 (kev pheej hmoo ntawm kev ua tsis tiav hauv qhov chaw ntub dej);
Kev vibration tuaj yeem ua rau kev sib cuag tsis zoo, ua rau muaj kev kub ntxhov hauv cheeb tsam ( ntsuas kub tuaj yeem ncav cuag 30K).
Qhov zoo ntawm qhov kaw -loop tsim:
IP65+ tag nrho kaw (epoxy resin casting), tiv taus plua plav thiab ntsev tsuag;
Tsis muaj qhov txav mus los, 25- xyoo tsim tsis muaj kev saib xyuas.
Cov ntsiab lus
- Kev xaiv cov transformers tam sim no rau cov ntsuas hluav taws xob yog qhov tseem ceeb ntawm peb - qhov sib npaug ntawm qhov raug, nqi, thiab kev pheej hmoo.
- Raws li kev lag luam ntawm kev tswj hwm kev siv hluav taws xob digital, kaw- voj tam sim no transformers (CTs) tseem yog "tus qauv kub" rau cov txheej txheem ntsuas qhov tseem ceeb, thaum qhib -loop CTs, nrog rau lawv cov kev hloov pauv kev ua haujlwm, tau dhau los ua cov cuab yeej tseem ceeb rau kev sib txuas ntxiv sib txuas thiab xoom- carbon transformation.
