1. Lus qhuab qhia
Rwb thaiv tsev kuj yog ib qho tseem ceeb qhia los txiav txim lub rwb thaiv tsev lub xeev ntawm lub hwj chim transformers thiab zoo soj ntsuam tej yam txhaum xws li winding luv circuits, core grounding, thiab winding plhaub hu. Txawm hais tias nws yog ib qho tshiab, kho dua tshiab lossis ntev ntev - lub sij hawm tawm - ntawm - kev pab cuam transformer, nws yog ib qho tsim nyog yuav tsum tau ua cov txheej txheem kev ntsuas rwb thaiv tsev ua ntej ua haujlwm kom muaj kev nyab xeeb thiab ruaj khov. Raws li cov chaw tsim khoom lag luam, JINSHANMEN TECHNOLOGY CO., LTD tsuas yog tsim cov roj immersed fais fab transformers, qhuav-hom fais fab transformers, roj immersed peb-dimensional coiled fais fab transformers, qhuav-hom peb-dimensional coiled fais fab transformers, mining{10} tawg tawg mining tawg- pov thawj mobile substations, amorphous alloy fais fab transformers, ntawm load peev xwm tswj fais fab transformers, locomotive qhuav- hom transformers, as well as prefabricated substations, modular substations, wind energy box type substations, high and low voltage switchgear and other transmission and distribution equipment.
2. Rwb thaiv tsev Resistance Standards
2.1 Cov Qauv Txheej Txheem (20 degree)
Lub rwb thaiv tsev tiv thaiv kev tsim nyog tus qauv ntawm lub zog transformers yog ze ze rau qhov voltage theem. Rau cov theem voltage ntau, cov kev cai tshwj xeeb yog raws li hauv qab no: 3-10KV Ntau dua lossis sib npaug rau 300MΩ, 20-35KV Ntau dua lossis sib npaug rau 400MΩ, 63-220KV Ntau dua lossis sib npaug rau 800MΩ, 500KV Ntau dua lossis sib npaug ntawm 3000.V voltage thiab qis dua, Ω ntau dua lossis sib npaug ntawm 3000. sib npaug 0.5MΩ. Rau kev khiav hauj lwm transformers, lub rwb thaiv tsev kuj yuav tsum tsis txhob tsawg tshaj li 10MΩ. A500kva kauj ruam down transformeryog siv dav hauv kev lag luam thiab kev lag luam, thiab nws qhov voltage feem ntau yog 10KV thiab qis dua. Yog li, nws cov rwb thaiv tsev tiv thaiv yuav tsum tsis pub tsawg dua 300MΩ ntawm 20℃kom tau raws li qhov yuav tsum tau ua.
2.2 Kev Tsim Nyog Ntxiv
Ntxiv nrog rau kev ua kom tau raws li qhov yuav tsum tau muaj kev tiv thaiv kev tiv thaiv, kev ntsuas kev tiv thaiv hluav taws xob ntawm cov hluav taws xob kuj yuav tsum tau ua kom tau raws li ob qhov tseem ceeb: Ua ntej, tom qab hloov tus nqi ntsuas mus rau qhov kub thiab txias, tam sim no tus nqi yuav tsum tsis txhob qis dua 30% qis dua tus nqi ntsuas dhau los; Qhov thib ob, qhov sib piv ntawm qhov nqus R60 / R15 (qhov piv ntawm cov rwb thaiv tsev ntawm 60 vib nas this mus rau 15 vib nas this thaum ntsuas) yuav tsum tsis pub tsawg tshaj 1.3 thaum qhov kub ntawm 10-30 degree. Rau cov roj immersed fais fab transformers, vim yog lub zog ntawm cov roj zoo, nqus dej noo thiab lwm yam, lub rwb thaiv tsev lub xeev feem ntau yuav deteriorate, yog li nws yog ib qho tseem ceeb kom ua raws li ob txoj cai ntxiv.
3. Cov khoom kuaj & ntsuas ntsuas
Thaum ntsuas qhov rwb thaiv tsev ntawm cov hluav taws xob hloov hluav taws xob, peb qhov tseem ceeb yuav tsum tau sim: qhov rwb thaiv tsev tiv thaiv ntawm siab -voltage winding thiab qis-voltage winding thiab lub plhaub (siab mus rau qis thiab hauv av), qhov rwb thaiv tsev tsis zoo ntawm qhov qis-voltage winding thiab siab -voltage winding thiab lub plhaub tsis zoo ntawm cov av thiab lub plhaub (qis). los ntawm - ntsia liaj qhov rooj thiab cov tub ntxhais (tsuas yog yuav tsum tau rau cov tub ntxhais- kev tshuaj xyuas overhaul). Rau 500 kva kauj ruam down transformer, kev xaiv cov cuab yeej ntsuas yuav tsum ua raws li qib winding voltage: 2500V megohmmeter rau windings saum 1000V, 1000V megohmmeter rau windings hauv qab 1000V, 500V megohmmeter rau 0.4KV qis {{14}V voltage transformers, 1000V voltage transformer los ntawm -bolt rwb thaiv tsev kuaj.
4. Cov yam ntxwv cuam tshuam rau rwb thaiv tsev tiv thaiv & txoj kev hloov pauv
Lub rwb thaiv tsev tsis kam ntawm lub zog hloov hluav taws xob cuam tshuam zoo heev los ntawm qhov kub thiab txias. Thaum cov av noo nce, qhov saum npoo thiab sab hauv ntawm lub transformer nqus dej noo, uas ua rau muaj zog to tam sim no thiab txo cov rwb thaiv tsev; Thaum qhov kub thiab txias, cov khoom siv hluav taws xob muaj feem ntau yuav ua rau hluav taws xob vim muaj kev txhim kho thermal zog, ua rau kom muaj hluav taws xob ntau ntxiv thiab txo cov rwb thaiv tsev. Yog li ntawd, tus nqi hluav taws xob tiv thaiv ntsuas ntawm qhov kub sib txawv yog qhov sib txawv, thiab qhov kub siab dua, qhov hluav taws xob tiv thaiv qis dua.
Rau qhov yooj yim ntawm kev ua haujlwm, peb tuaj yeem siv cov qauv thiab mnemonic los hloov cov nqi rwb thaiv tsev rau 20℃rau kev sib piv: cov qauv hloov pauv yog R20=Rt × 10^((t−20)/40); lub mnemonic yog "ib nrab thaum nce los ntawm 10 degree, ob npaug thaum txo los ntawm 10 degree, multiply los ntawm 1.5 rau zoo rwb thaiv tsev". Txoj kev no kuj muaj feem xyuam rau lub rwb thaiv tsev tsis kam hloov ntawmroj immersed hwj chim transformersthiab 500 kva kauj ruam down transformers.
5. Kev tswj tsis zoo & ceev faj
Yog tias qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qis dua 50% ntawm tus nqi dhau los (tom qab hloov pauv kub), kev saib xyuas yuav tsum tau teem caij tam sim; Yog tias qhov sib piv ntawm qhov nqus tsis tau raws li tus qauv (tsawg dua 1.3), qhov kev sim dielectric poob yuav tsum tau muab ntxiv los txiav txim rau lub xeev rwb thaiv tsev. Nws yuav tsum tau muab sau tseg hais tias cov tshiab tau nruab thiab overhauled transformers yuav tsum tau raws li tag nrho cov saum toj no cov qauv tsim nyog ua ntej lawv yuav energized thiab muab tso rau hauv lub lag luam.
6. Cov lus xaus
Kev ntsuas tsis tu ncua ntawm transformer rwb thaiv tsev tiv thaiv yog ib qho tseem ceeb txhais tau tias kom muaj kev nyab xeeb ntawm kev siv hluav taws xob transformers, uas tuaj yeem tiv thaiv cov khoom tsis zoo los ntawm kev rwb thaiv tsev deterioration.JINSHANMEN TECHNOLOGY CO., LTDmuaj kev nplua nuj nyob rau hauv kev tsim cov transformers, thiab nws cov roj immersed hwj chim transformers thiab 500 kva kauj ruam down transformers muaj kev ruaj ntseg rwb thaiv tsev kev ua tau zoo, uas muaj peev xwm ua tau raws li lub rwb thaiv tsev cov qauv tsim nyog ntawm ntau theem voltage. Yog tias koj muaj kev xav tau ntawm cov khoom lag luam lossis kev xav tau kev pab tswv yim, txais tos hu rau peb.
