Tiv thaiv a3-theem transformersuav nrog kev siv ntau yam kev tiv thaiv kom ntseeg tau tias nws muaj kev nyab xeeb thiab txhim khu kev qha. Nov yog qee txoj hauv kev los tiv thaiv 3-theem transformer:
- Kev tiv thaiv overcurrent: Nruab cov khoom tiv thaiv overcurrent xws li fuses lossis Circuit Court breakers nyob rau hauv thawj thiab theem nrab circuits ntawm lub transformer. Cov cuab yeej no ntes thiab cuam tshuam cov dej ntws ntau dhau, tiv thaiv kev puas tsuaj rau lub tshuab hluav taws xob windings thiab lwm yam khoom.
- Kev tiv thaiv sib txawv: Kev tiv thaiv sib txawv yog ib txoj hauv kev siv los tiv thaiv transformer. Nws suav nrog kev sib piv cov tam sim no nkag mus thiab tawm hauv cov transformer windings. Txhua qhov sib txawv ntawm qhov tam sim no qhia tau hais tias muaj kev ua txhaum nyob rau hauv lub transformer, xws li winding luv Circuit Court. Qhov sib txawv relays yog siv los xyuas cov kev ua txhaum no thiab mus rau lub Circuit Court breaker kom cais cov transformer ntawm qhov system.
- Buchholz Relay: Buchholz relay yog ib qho roj thiab roj ua haujlwm relay ntsia rau hauv cov kav dej ntawm lub tank transformer thiab conservator. Nws muab kev tiv thaiv sab hauv, xws li transformer core faults los yog winding rwb thaiv tsev tsis ua hauj lwm. Lub relay ntes cov tsub zuj zuj ntawm cov pa roj los yog roj vim yog sab hauv arcing los yog overheating thiab pib lub tswb los yog lub teeb liab mus rau cais lub transformer.
- Kev ntsuas kub: Transformers tsim kom muaj cua sov thaum lub sijhawm ua haujlwm, thiab qhov kub ntau dhau tuaj yeem ua rau cov rwb thaiv tsev thiab lwm yam khoom puas. Cov cuab yeej ntsuas kub xws li ntsuas kub ntsuas (RTDs) lossis cov thermocouples yog siv los ntsuas qhov ntsuas kub ntawm ntau qhov tseem ceeb hauv transformer. Lub tswb thiab cov cim kev mus ncig tau qhib yog tias qhov kub siab tshaj qhov txwv tsis pub dhau.
- Kev tiv thaiv overvoltage: Cov xwm txheej overvoltage tuaj yeem tshwm sim vim yog xob laim tawm tsam, hloov kev ua haujlwm, lossis ua txhaum ntawm lub zog hluav taws xob. Nruab surge arresters lossis voltage limiting li ntawm lub transformer terminals los tiv thaiv overvoltage transients. Cov cuab yeej no hloov hluav taws xob ntau dhau mus rau hauv av, tiv thaiv lub rwb thaiv tsev transformer.
