Yuav Ua Li Cas Xaiv Ib Ntawm -Load Tap Changer Tester: Basic vs Full Spec

Tus OLTC tester khwv tau nws khaws tsuas yog tias nws ntsuas kom raug, qhia txog kev hloov pauv, sau npe qhov tsis xws luag, thiab khaws cov ntaub ntawv koj tuaj yeem rov qhib hauv peb xyoos. Lub thawv pheej yig dua uas tsuas yog luam tawm lub sijhawm hloov pauv thiab tus lej tiv thaiv yuav dhau qhov kev kuaj xyuas niaj hnub thiab tsis nco qab, qhib, lossis theem lag luam uas tau siv lub tshuab hloov pauv.

Vim li cas tus nqi- tsuas yog yuav tsis tau

Cov nqi txiav feem ntau yog thaj av ntawm qhov chaw uas koj tsis tuaj yeem pom ntawm daim duab hauv daim ntawv qhia: thaj tsam tam sim no, piv txwv thiab waveform fidelity, peb -theem synchronism, suab nrov tsis lees paub, thiab tuav cov ntaub ntawv. Cov neeg txiav txim siab seb lub tsev puas npog koj lub nkoj, txawm tias lub dav hlau yog qhov teeb meem kev sib cuag tiag tiag lossis lub suab nrov substation, thiab seb koj puas tuaj yeem hloov pauv tib yam tom qab kev kho dua tshiab. Qhov sib txawv ntawm cov twj paj nruag tsis yog "nws tuaj yeem tso tawm tus lej." Nws yog qhov tob npaum li cas, seb koj puas tuaj yeem pom cov txheej txheem, thiab seb cov ntaub ntawv puas tseem muaj nyob thaum cov neeg coob tom ntej tuaj txog.

Kev xyaum ua lag luam (DRM / DVtest, raws li siv los ntawm cov khoom siv hluav taws xob nrog Megger, Omicron, thiab cov platform zoo sib xws) kho cov kab mob dynamic raws li kev kuaj mob, tsis yog qhov zoo li qub -kev nyeem ntawv ib leeg.

Peb qhov sib txawv ntawm qhov pib thiab tag nrho -spec

Tag nrho cov dynamic waveform - Koj puas tuaj yeem pom qhov qhib, luv luv, thiab tiv tauj bounce, lossis tsuas yog ob daim duab?

Muaj tseeb peb-theem sync - Koj puas tuaj yeem txiav txim siab kev sib koom tes ntawm ib qho kev ntes? Ib ntus ib zaug -theem txhaj tshuaj tsis yog qhov hloov pauv; peb tus ncej yog mechanically txuas thiab yuav tsum overlay.

Kev tswj cov ntaub ntawv - Koj puas tuaj yeem muab qhov kev txiav tawm no nrog rau kev ua haujlwm hauv paus? Yog tsis muaj qhov ntawd, qhov xwm txheej -raws li kev saib xyuas yog cov lus hais.

Tam sim no ntau yam thiab sampling zaum hauv qab tag nrho peb. Ntau qhov ntau txhais tau tias ntau hom kev hloov pauv thiab lub teeb liab huv dua - mus rau - suab nrov piv. Sampling nyob ib ncig ntawm 20 kHz (raws li ntawm HZYA-2Z / HZYA-2Z-I) yog nyob rau hauv cov qhab siv rau lub sijhawm muaj txiaj ntsig DRM; cov zaub sluggish yuav smear ib millisecond tshwm sim rau hauv ib tug du nkhaus uas zoo li noj qab nyob zoo.

Plaub thaj tsam ntawm kev yuav khoom

Ntawm Huazheng txoj kab, HZYA-3Z ntxiv 2.0 A ntau yam (0.5-5 Ω) saum toj ntawm 1.0 / 0.5 / 0.2 A, uas tseem ceeb rau qis dua -ohm hloov pauv. HZYA-2Z-Kuv yog 2 kg handheld, lithium{16}}powered, 500 cov ntaub ntawv, 13 m leads- haum rau ib leeg-unit teb ua hauj lwm yog hais tias koj tseem tau txais waveform thiab peb-theem nyeem ntawv, tsis tsuas yog ib tug pass teeb.

Leej twg yuav tsum yuav high spec-thiab leej twg yuav tsum tsis

Yuav tag nrho -spec, peb-theem, ntau- ntau yam, nrog rau cov ntaub ntawv khaws cia yog tias koj hloov kho kos npe- tawm, nrhiav qhov tsis raug, ntsuas qhov xwm txheej, lossis thib peb- cov lus ceeb toom ntawm tog neeg: pab pawg kuaj hluav taws xob, khw muag khoom, chaw tsim hluav taws xob, thiab cov chaw sim ua haujlwm ywj pheej.

Nyob nrog ib qho yooj yim lossis nruab nrab - chav tsev yog tias koj tsuas yog rov lees paub qhov paub zoo - hloov pauv zoo, sim ib qho qauv tsim, thiab tsis muaj qhov kev kuaj mob. Them rau lub cev muaj zog- cov channel tam sim no, kev vibration, thiab tus kws sau keeb kwm uas koj yuav tsis qhib tsis yog kev ceev faj.

Nug tus neeg muag khoom kom pom peb -theem overlay los ntawm OLTC resistive thiab los ntawm reactor- hom hloov ua ntej koj kos npe. Yog tias lawv tsuas tuaj yeem qhia ob tus lej ntawm cov ntawv thermal, taug kev mus.
