Xaiv cov khoom siv ntsuas hluav taws xob thib ob raws li qhov yuav tsum tau ua ntawm qhov chaw hinges kom meej meej lub hom phiaj kev xeem, hom kab ke, qhov yuav tsum tau muaj tseeb, thiab ib puag ncig kev ua haujlwm. Hauv qab no yog cov lus qhia xaiv rau qhov sib txawv daim ntawv thov scenarios los pab koj kom haum cov khoom siv:
Xaiv cov cuab yeej tseem ceeb raws li kev sim cov hom phiaj
Relay Protection Function Verification: Yog tias kuaj xyuas qhov kev khiav haujlwm, cov yam ntxwv ntawm lub sijhawm, lossis tag nrho kev sib kis ntawm cov cuab yeej tiv thaiv yuav tsum tau siv, yuav tsum siv tus microprocessor -raws li relay tiv thaiv tester. Nws tuaj yeem simulate ntau yam txhaum tam sim no thiab voltages thiab yog tsim rau commissioning scenarios xws li transformer thiab kab tiv thaiv.
Metering Accuracy Optimization: Yuav kom txo tau lub zog metering yuam kev, tshwj xeeb tshaj yog deviations tshwm sim los ntawm PT theem nrab voltage poob, ib tug tag nrho tsis siv neeg theem nrab voltage ntsuas ntsuas yuav tsum tau siv. Cov cuab yeej no txhawb nqa peb -theem peb-hlau / plaub-wire tsis siv neeg ntsuas, tuaj yeem ncaj qha xam qhov yuam kev ua ke, thiab muaj peev xwm tiv thaiv siab - cuam tshuam.
Instrument Transformer Performance Testing:
CT / PT Ratio thiab Polarity Verification: Siv tus qauv ntsuas qhov sib piv lossis lub polarity calibrator kom paub meej qhov tseeb ntawm cov xov hlau.* CT Excitation Characteristic Analysis: CT analyzer raug xaiv los ntsuas qhov volt- ampere yam ntxwv thiab 10% kev ua yuam kev nkhaus, kom ntseeg tau tias kev tiv thaiv CT tsis fwm.
Conductive Circuit Health Status Check: Rau cov teeb meem kev sib cuag tsis zoo hauv Circuit Court breakers thiab disconnectors, siv lub ntsuas hluav taws xob thib ob. DC voltage drop method (plaub-terminal method) yog ua haujlwm kom raug ntsuas micro-ohm tsis kam, tiv thaiv overheating faults.
Optimizing Equipment yam ntxwv raws li qhov chaw nyob:
Kev xav tau siab nqa tau yooj yim (piv txwv li, chaw nres tsheb sab nraum zoov): Handheld, lithium- cov khoom siv roj teeb yog nyiam dua. Piv txwv li, CZ3140 circuit resistance tester hnyav tsuas yog 1.5kg thiab txhawb kev ua haujlwm hauv ib puag ncig yam tsis muaj AC fais fab.
Muaj zog Electromagnetic cuam tshuam (piv txwv li, kev khiav hauj lwm switchyards): Cov cuab yeej siv digital filtering thiab inter-frequency testing technology raug xaiv los tswj 50Hz fais fab zaus cuam tshuam thiab xyuas kom ruaj ntseg nyeem ntawv.
Ntau-Kev Ua Haujlwm Ua Haujlwm Zoo: Kev pom zoo ua kom muaj kev sib tw ua tiav. Ib lub cuab yeej tuaj yeem ua tiav ntau yam kev ntsuas xws li PT voltage poob thiab CT load, txo cov xaim thiab hloov sijhawm thiab txhim kho ntawm - qhov chaw ua haujlwm.
