Kev faib tawm transformer nrog lub peev xwm ntau dhau muaj peev xwm muaj peev xwm tiv taus siab thiab tiv thaiv lub tshuab hluav taws xob los ntawm kev kub hnyiab vim overload. Nws tsis tsuas yog tuaj yeem tiv nrog lub caij nyoog thauj khoom siab tshaj plaws, tab sis kuj tuaj yeem tswj hwm tus nqi siab hauv lub hlis ib txwm, tab sis kuj tuaj yeem txo tus nqi ntawm kev ua haujlwm thiab kev saib xyuas, kev lag luam zoo. Lub siab overload transformer tuaj yeem khiav rau 6h ntawm 1.5 npaug ntawm qhov ntsuas load, 3h ntawm 1.75 npaug ntawm qhov ntsuas load, thiab 1h ntawm 2 npaug ntawm qhov ntsuas load. Nws muaj peev xwm daws tau qhov teeb meem kub ntawm transformer vim lub sij hawm luv luv high overload tsis cuam tshuam rau lub neej kev pab cuam ntawm transformer.

Nyob rau hauv qhov kev pom ntawm qhov nruab nrab qhov nruab nrab ntawm qhov nruab nrab qis qis hauv cov neeg nyob deb nroog thiab lub sij hawm luv luv thiab kev nce ntau hauv kev thauj khoom thaum lub caij nplooj ntoos hlav Festival thiab lub sijhawm ua liaj ua teb tsis khoom, kev siv qhov xwm txheej no, ntawm qhov chaw ntawm kev ua kom muaj peev xwm ntawm cov hluav taws xob yooj yim, tsis yog xwb. ua tau raws li qhov kev thov mus sij hawm ntev rau me me load hluav taws xob, tab sis kuj yuav siv sij hawm mus rau hauv tus account lub sij hawm luv luv thov rau overload hluav taws xob.

High overload fais fab faib transformer muaj lub zog txuag thiab ua haujlwm siab. Kev tiv thaiv ib puag ncig, me me tsis muaj-load tam sim no, tsis tshua muaj hluav taws xob reactive poob, muaj zog tiv thaiv tam sim ntawd luv luv Circuit Court.

Cov cuab yeej siv hluav taws xob faib hluav taws xob nrog lub peev xwm ntau dhau yog txhawm rau txhim kho cov qauv faib hluav taws xob. Los ntawm kev nce tus naj npawb ntawm qhov siab thiab qis voltage winding roj raws ntawm lub transformer (uas yog, ua kom qhov chaw txias ntawm cov windings), lub inter-tig voltage tester tuaj yeem txo qhov kub ntawm qhov windings mus rau cov roj thiab tiv thaiv lub zos overheating. ntawm cov windings tom qab overload ntawm lub transformer.

Ua kom qhov chaw txias ntawm cov roj tank, SBF triple zaus generator txo qhov kub thiab txias ntawm cov roj ntawm lub transformer rau sab nraud; Los ntawm kev xaiv cov khoom siv hluav taws xob kub kub, txhim kho cov cua sov ua haujlwm ntawm cov khoom sib txuas thiab cov khoom siv rwb thaiv tsev, txhim kho cov khoom siv hluav taws xob hluav taws xob kub kub, los txhim kho qhov kev faib hluav taws xob ntau dhau ntawm kev tsim qauv.

Rwb thaiv tsev kub tswj tshuab: cov ntaub ntawv rwb thaiv tsev sib txawv raug xaiv raws li qhov kub ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov cua thiab lub cev los tswj qhov kub ntawm qhov kub ntawm qhov cua.

Overload kub tswj tshuab: qhov kub thiab txias faib yog txawv ntawm overload thiab rated load. KD2675 series rwb thaiv tsev tiv thaiv tester tuaj yeem xam qhov tsim nyog thiab tswj qhov kub thiab txias ntawm ntau qhov chaw ntawm lub transformer nyob rau hauv overload.

Kev tswj qhov kub thiab txias: tswj kev cuam tshuam ntawm thermal expansion, deformation thiab lub zog tshwm sim los ntawm qhov kub thiab txias hloov ntawm cov kua thiab roj tank, ntxiv los ntawm cov ntsaws ruaj ruaj zoo, los xyuas kom meej qhov kev ua haujlwm ntawm transformer nyob rau hauv nws qhov kev tso cai kub ntau yam.

Cheebtsam kub tswj tshuab: Cheebtsam raws li nws txoj hauj lwm kub, xaiv cov qib sib thooj ntawm cov khoom rwb thaiv tsev.

Short-circuit kub tswj tshuab: nyob rau hauv cov ntaub ntawv ntawm transformer txhaum short-circuit, lub luv luv-circuit tam sim no tus nqi ntws los ntawm winding ntawm ed0204-iii peb-channel dc kuj tester yog loj, tab sis lub sij hawm luv luv. Lub tshav kub tsub zuj zuj thiab kub dissipation nyhuv nyob rau hauv reclosing xeev yog xam.

Scope ntawm daim ntawv thov

Siv dav hauv thaj chaw nyob, cov chaw pej xeem, kev lag luam thiab kev lag luam mining thiab lwm qhov chaw faib hluav taws xob. Nws yog dav siv nyob rau hauv industrial parks, thaj chaw nyob, chaw ua lag luam thiab cov tsev siab. Tshwj xeeb tshaj yog haum rau kev hloov pauv ntawm kev ua liaj ua teb network; Nws kuj tseem tsim nyog rau thaj chaw nyob thiab cov lag luam thiab cov tsev kawm ntawv uas muaj qhov sib txawv loj hauv hluav taws xob nruab nrab nruab hnub thiab hmo ntuj.
