Lub nplhaib hom LV CT
Cov nplhaib hom LV CT (RCT-110) yog tsim rau sab hauv tsev qis- cov ntawv siv hluav taws xob (0.66kV), ua haujlwm ntawm 50/60Hz. Qhov zoo tshaj plaws rau kev ntsuas tam sim no lossis muab kev tiv thaiv relays, lawv yog cov compact, lub teeb yuag, thiab feature lub cev muaj zog molded tag nrho. Installation yog yooj yim los ntawm kev ruaj ntseg vaj huam sib luag-mounting nrog ib tug tshwj xeeb bracket.

Txheej txheem cej luam ntawm lub nplhaib -hom LV CT
Lub nplhaib-hom LV CT (tseem hu ua lub qhov rais-hom lossis khob noom-hom CT) yog lub tshuab hloov tam sim no tsim los ntsuas qhov hloov pauv tam sim no (AC) hauv qis-voltage hluav taws xob tshuab. Nws lub ntsiab lus txhais yog ib qho khoom, tsis muaj kev cuam tshuam lub nplhaib ntawm ferromagnetic core nrog ib tug thib ob winding qhwv nyob ib ncig ntawm nws. Tsis muaj thawj winding; Hloov chaw, tus neeg xyuas pib nqa tam sim no los ntsuas (tus neeg xyuas pib) tsuas yog hla lub qhov rais nruab nrab.
Qhov no ua rau nws yog ib qho kev daws teeb meem zoo tshaj plaws rau retrofitting mus rau cov khoom siv hluav taws xob uas twb muaj lawm yam tsis tas yuav tsum tau txiav tawm lossis tawg lub voj voog.
Cov yam ntxwv tseem ceeb & tsim
- Nws ua haujlwm li cas (Txoj Cai Ua Haujlwm):
Nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction.
AC tam sim no (I_p) hauv thawj tus neeg xyuas pib (piv txwv li, lub busbar lossis cable) tsim kom muaj qhov sib nqus sib nqus.
Qhov no magnetic teb circulates nyob rau hauv lub CT's core.
Qhov hloov magnetic teb induces ib proportional alternating tam sim no (I_s) nyob rau hauv lub thib ob winding.
Qhov piv ntawm thawj mus rau theem nrab tam sim no yog tsau. Piv txwv li, 100: 5 CT yuav tsim 5 amps hauv lub voj voog thib ob thaum 100 amps ntws los ntawm thawj tus neeg xyuas pib.
2. "Qhov rai":
Lub qhov hauv nruab nrab yog qhov tseem ceeb. Nws yuav tsum loj txaus kom haum tus thawj neeg xyuas pib (s). Qhov ntau thiab tsawg los ntawm tsuas yog loj txaus rau ib lub cable mus rau loj diameters rau busbars los yog ntau cables.
Qhov zoo ntawm Nplhaib -Hom CTs
✔ Tsis yog -Invasive Installation: Qhov zoo tshaj plaws. Lawv tuaj yeem ntsia tau rau ntawm kab nyob yam tsis muaj kev cuam tshuam, txo qis qis qis.
✔ Nqis -Zoo: Tsis muaj thawj winding txo cov khoom siv thiab cov nqi tsim khoom.
✔Compact thiab Lightweight: Ib qho yooj yim los lis thiab mount nyob rau hauv cov neeg coob coob panels.
✔Rovust thiab Yooj Yim: Tsawg qhov chaw txhais tau tias muaj kev ntseeg siab dua.
✔Flexible: Ib qho CT loj tuaj yeem siv rau ntau yam ntawm cov thawj tam sim no los ntawm kev hloov tus naj npawb ntawm lub sij hawm tus neeg xyuas pib hla lub qhov rais (piv txwv li, looping lub cable ob zaug ib nrab ntawm qhov piv).
Cov ntawv thov siv
Nplhaib-hom LV CTs muaj nyob txhua qhov chaw hauv qis-voltage hluav taws xob tshuab rau:
- Kev ntsuas hluav taws xob: Kev siv ntau tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv kev lag luam thiab kev lag luam hluav taws xob ntsuas los ntsuas kev siv hluav taws xob rau kev them nqi lossis sub- nqi.
- Hluav taws xob vaj huam sib luag Instrumentation: Pub cov kev nyeem tam sim no mus rau analog ammeters lossis cov duab digital ntawm cov keyboards.
- Kev Tiv Thaiv Relaying: Muab qhov ntsuas - nqes tam sim no rau kev tiv thaiv relays uas ntes overcurrent, lub ntiaj teb faults, thiab lwm yam.
- Fais fab Kev Ntsuam Xyuas: Siv nrog cov ntsuas ntsuas ntsuas kev sib haum xeeb.
RCT-110 nplhaib hom LV CT rau Sab Hauv Tsev Zog thiab Kev Tiv Thaiv Daim Ntawv Thov
RCT-110 series nplhaib hom LV CT yog tsim los siv rau sab hauv tsev nyob rau hauv qis-voltage AC systems nrog lub siab tshaj plaws kev khiav hauj lwm voltage ntawm 0.66kV. Tau tshaj ob qho tib si 50Hz thiab 60Hz fais fab mov qauv, cov khoom siv no yog tsim los ua kom muaj kev ua tau zoo nyob thoob plaws ntau qhov chaw hluav taws xob thoob ntiaj teb.
Qhov zoo tshaj plaws rau cov ntawv thov xws li kev ntsuas hluav taws xob, kev saib xyuas kev thauj mus los, kev kuaj xyuas qhov tsis raug, thiab kev xa rov qab-raws li kev tiv thaiv, RCT-110 muab qhov tseeb thiab txhim khu kev qha tam sim no rau kev hloov pauv, tswj vaj huam sib luag, faib cov boards, thiab kev lag luam automation systems. Nws txoj kev tsim kho toroidal ua kom tsis muaj qhov sib nqus tam sim no thiab siab linearity thoob plaws qhov ntsuas ntau.
Lub transformer yog tag nrho encapsulated nyob rau hauv ib tug siab - rwb thaiv tsev molded composite vaj tse, uas muaj tshwj xeeb tsis kam rau cov av noo, plua plav, tshuaj, thiab mechanical kev nyuaj siab. Qhov kev tsim no tsis tsuas yog txhim kho kev nyab xeeb ntawm kev ua haujlwm tab sis kuj tseem txuas ntxiv cov khoom lag luam kev pabcuam lub neej nyob rau hauv ib puag ncig nyuaj. Lub compact thiab lub teeb yuag profile ua kom yooj yim tuav thiab qhov chaw - txhim khu kev qha, txawm nyob hauv cov khoom siv hluav taws xob hnyav.
Ib qho tshwj xeeb mounting bracket yog suav nrog los ua kom ceev, ruaj ntseg, thiab cov cuab yeej- txo qis sib dhos rau cov vaj huam sib luag. Lub bracket no ua kom ruaj khov kho, txo lub sijhawm teeb tsa, thiab tswj xyuas kev sib cuag nrog kev vibration lossis thermal variation.
Muaj ntawv pov thawj rau kev ua haujlwm thoob ntiaj teb thiab cov qauv kev nyab xeeb, RCT-110 muab cov kev ua haujlwm siab, ua haujlwm ntev, thiab cov neeg siv- kev teeb tsa tus phooj ywg, ua rau nws muaj ntau yam kev daws teeb meem rau niaj hnub ntsuas hluav taws xob qis thiab kev tiv thaiv.
