Rau nruab nrab kom high - voltage transformers, tshwj xeeb yog cov nyob nruab nrab ntawm35KV thiab 110Kv, tusNyob rau - Pead Take Changer (OLTC)Ua si lub luag haujlwm tseem ceeb hauv kev txhim kho ruaj khov thiab muaj txiaj ntsig voltage. Lub ntsiab lus tseem ceeb no tso cai hloov mus raukho cov zis voltage nyob rau hauv load tej yam kev mobYog tsis muaj kev pabcuam kev cuam tshuam, ua rau nws tseem ceeb hauv cov nqi hluav taws xob, hloov chaw, thiab cov ntawv thov loj.
OLTC yog dab tsi?
IbNyob rau - Pead Take Changer (OLTC)Yog ib lub tshuab hloov mus rau hauv lub zog hloov hluav taws xob uas hloov kho tus naj npawb ntawm lem hauv lub transformer lub winding thaum lub chav nyob kom energized thiab hauv qab thauj khoom. Txoj kev hloov pauv no pab tswj hwmKev ntsuas hluav taws xob tas liNyob rau sab thib ob txawm tias muaj kev hloov pauv hauv kev muab khoom lossis thauj khoom.
Nyob rau hauv a35kv rau 110kv roj -}} umped transformer, OLTCS feem ntau tau nruab rau qhov siab - voltage winding thiab muab5% rau ± 10% Coj mus rhaub, nyob ntawm cov cai yuam kev.
Cov haujlwm tseem ceeb ntawm OLTC nyob rau hauv high - voltage transformers
- Kev cai voltage: OLTC ua kom cov zis voltage tseem nyob hauv kev txwv uas pom tau, uas yog qhov tseem ceeb rau kev ruaj khov.
- Thauj khoom sib npaug: Kho voltage kom haum raws sib txawv thauj khoom hauv lub sijhawm.
- Kev Txhim Kho Lub Koom Haum: Tiv thaiv kev ua haujlwm los yog undervoltage scararios uas tuaj yeem ua rau cov khoom siv rhiab rhiab.
Aum txij nkawm thiab tshuaj xyuas
Vim nws cov chaw txav chaw thiab cov khoom siv hluav taws xob, lub OLTC yog ib qho ntawm feem ntau txij nkawm - intimers ntawm ib transformer. Cov Upkeep yog qhov tseem ceeb rau kev ua tau zoo thiab thiav.
Cov Haujlwm Saib Xyuas Kev Coj Nrog:
- Kev kuaj cov roj thiab tshuaj xyuas: OLTC Compartartments siv cov roj insulating kom txias thiab tsis muaj peev xwm tiv thaiv. Cov tsheb ntsuas roj ib txwm pab txhawm rau txhawm rau kho cov pa roj teeb lossis dej noo.
- Hu Rau Cov Hnov Tes Taw: Cov neeg tiv toj yuav tsum tau tshuaj xyuas thiab hloov ntu kom tiv thaiv arc puas tsuaj.
- Kev Ntsuas Cov Ntsuas: Ntes Anomalies hauv kev hloov pauv hloov lossis tiv tauj kom muaj kev cuam tshuam.
- Tswj Relay Kev Ntsuas: Kom ua kom muaj zog hloov thiab tiv thaiv tus cwj pwm.
Rau110Kv thiab saum toj no, Caw Nkawv OLTC Xyuas Lub TshuabFeem ntau siv los sau hloov chaw ua haujlwm, ntsuas kub, thiab roj roj, tso cai ua kev saib xyuas thiab txo cov kev sib tw tsis muaj teeb meem.
