Series YTJLW10-720 Voltage Transformers
Derating
Series YTJLW10-720 theem sib lawv liag, xoom sequence voltage thiab tam sim no transformer yog ib yam ntawm AC transformers nrog kev specifications uas ua raws li cov thawj thiab theem nrab fusion khoom ntawm lub State Grid thiab raws li T / CES 018-2018 "Kev faib Network 10kV thiab 20kV AC Transformers Technical Conditions "Voltage, tam sim no thiab fais fab transformers yog tsim rau hauv cov khoom, uas tuaj yeem ncaj qha sib dhos nrog Circuit Court breaker los ua ib qho kev txawj ntse nqus Circuit Court breaker.easy rau nruab, tsawg zog noj, siab raug thiab ruaj khov ntsuas.
■ Lub ntsiab capacitor siv qhov sib npaug capacitance los sau cov khoom siv hluav taws xob, uas muaj kev ruaj ntseg zoo thiab kev ua haujlwm ntev hauv cov phiaj xwm hluav taws xob.
■ Cov zis sab hauv kuj yog me me, uas tuaj yeem hloov mus rau ntau lub cables, kov yeej qhov yuam kev los ntawm cov cables, thiab qhov kev sib hloov ntawm cov cable yog tsawg dua 0.1%.
■ Kev hloov pauv me me cuam tshuam los ntawm qhov kub thiab txias, thiab qhov kev hloov pauv siab tshaj plaws yog tsawg dua 0.5% hauv qhov ntsuas kub tag nrho ntawm -40 ° C ~ 70 ° C, uas ua tau raws li qhov xav tau ntawm qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas ntawm 3-theem transformer teev.
■ txais yuav lub zog ruaj khov thiab tsis tshua muaj zog tub ntxhais winding, zoo tso zis ruaj khov thiab siab precision, thiab ua tau raws li kev ua haujlwm ntawm txhua yam kev ua haujlwm.

Txoj kev teeb tsa
Installation cov lus qhia thiab ceev faj
■ Xyuas kom ntseeg tau tias kev sib cuag ntawm cov xaim hauv av thiab cov vaj tsev thaum lub sijhawm teeb tsa.
■ Lub teeb liab tso zis theem ob ntawm lub transformer yuav tsum tau txuas nrog rau lub thawv, thiab cov hlau lead ntau dhau yuav tsum raug txiav luv.
■ Qhov thib ob qhov hluav taws xob tso tawm ntawm lub transformer rau hauv av yog txwv tsis pub ua hauj lwm zaus withstand voltage
■ Cov lus qhia rau kev txuas txuas ntxiv
| HOM | Rated transformation piv | Kev txheeb xyuas qhov hluav taws xob | lus hais |
| Tam sim no theem ib ntus | 600A / 1V | Ia+Ia-,Ib+Ib-,Ic+Ic- | |
| Tam sim no xoom sequence | 20A / 0.2V | Kuv 0+ I0- | Identity I0+ I0- raws li Txuas cov kab hloov pauv |
| Voltage theem sequence | 10kV / √3 / 3.25V / √3 | Ua+Ua-Ub+Ub-Uc+Uc- | |
| Voltage zero sequence | 10kV / √3 / 6.5V / 3 | U0+ U0- | Identity U0+ raws li Txuas cov kab hloov pauv |
Txij li thaum lub zero-sequence tam sim no thiab xoom-sequence voltage yuav tsum tau peb-theem synthesis, yuav tsum tau rau nruab nrab txoj kev hloov kab kev twb kev txuas, txhua theem I0 +, I0- sib txuas rau plugging;U0+ ntawm txhua theem sib raug rau kev sib tw.Ua ntej tawm hauv lub Hoobkas, cov khoom tau raug docked, thov kos nws thaum txhim kho.Raws li hauv qab no:
