Kuv yuav ua li cas yog tias lub ntsiab Circuit Court ntawm lub inverter tsis ua haujlwm?

Raws li kev txheeb cais ntawm qhov zaus thiab lub sijhawm poob ntawm qhov tshwj xeeb tsis ua haujlwm ntawm lub inverter, kev kho tus nqi ntawm lub zog loj ntawm cov khoom siv hluav taws xob ntau tshaj 60%; Kev teeb tsa tsis raug ntawm qhov kev ua haujlwm tseem ceeb, ua rau kwv yees li 20% ntawm kev ua tsis tiav; Kev ua txhaum ntawm kev tswj xyuas Circuit Court boards account rau 15%; 5% ntawm kev ua tsis tiav yog tshwm sim los ntawm kev ua haujlwm tsis raug thiab kev tsis txaus ntseeg sab nraud. Raws li kev txheeb cais ntawm cov theem ntawm kev ua txhaum cai thiab qhov nyuaj ntawm kev daws lawv, qhov tshwm sim ntawm cov kev ua txhaum no yuav ua rau muaj kev puas tsuaj thiab kev puas tsuaj ntawm cov khoom siv hluav taws xob. Qhov no yog ib feem tseem ceeb ntawm tus nqi ntawm AC tsav tu. Yuav ua li cas thaum ntsib qhov tsis ua hauj lwm ntawm lub ntsiab Circuit Court

(1) Kev puas tsuaj rau lub rectifier thaiv Kev puas tsuaj ntawm lub raj rectifier kuj yog ib qho teeb meem ntawm cov inverter. Lub rectifier thaiv ntawm lub inverter tsim nyob rau hauv thaum ntxov hnub yog tsuas yog ib tug diode rectifier. Nyob rau theem no, ib co rectifier blocks siv thyristor rectifier txoj kev (variable voltage radio broadcast zaus converter). Feem ntau, lub rectifier module ntawm nruab nrab thiab siab zog inverters yog peb-theem puv-yoj rectifier. Lub rectifier, uas yog lub luag haujlwm rau tag nrho cov hluav taws xob hluav taws xob hluav taws xob tawm ntawm lub inverter, nws yog qhov ua rau overheating thiab nkag mus. Tom qab kev puas tsuaj, lub inverter tsis txuas, kev tuav pov hwm kev lag luam raug cuam tshuam, peb-theem input lossis output terminals muaj tus nqi qis (thaum txhua yam nyob rau hauv kev txiav txim, tus nqi kuj yog siab dua megohm) los yog luv luv Circuit Court txhaum. Thaum tshem tawm thiab hloov lub rectifier thaiv, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo txheej txheej ntawm lub tshuab hluav taws xob nrog ib txheej ntawm silicon thermal paste nrog cov thermal conductivity zoo, thiab tom qab ntawd nruj cov screws. Yog tsis muaj tib lub rectifier thaiv, nws tuaj yeem hloov nrog lwm hom rectifier block nrog tib lub ntim. Ua ntej kev teeb tsa thiab xaim, kho cov ntsia hlau qhov yuav tsum tau xuas nrig ntaus thiab tapping dua. Piv txwv li, nyob rau hauv nruab nrab-rau-lig 80s ntawm lub xyoo pua 20th, tom qab lub inverter (7.5kVA) rectifier module (elliptical hom) tsim los ntawm Siemens PLC tau nkag mus, vim tsis muaj qhov zoo sib xws rectifier thaiv qhov chaw, rectifier thaiv (cov duab plaub. ncej) ntawm tib lub ntim tsim los ntawm Sanken raug xaiv los hloov. Nws tau ua haujlwm tau ntau xyoo thiab tseem ua haujlwm nyob rau theem no.

(2) Lub roj teeb them hluav taws xob ntawm lub inverter yog yooj yim puas rau cov laj thawj hauv qab no: yog AC contactor ntawm lub ntsiab tswj Circuit Court tsis raug kaw zoo, lub sijhawm nqa tam sim no ntev dhau lawm, thiab lub roj teeb them tus nqi hluav taws xob raug hlawv; los yog qhov tsis kam kub hnyiab tawm vim yog qhov tam sim no ntau dhau; Los yog vim hais tias ntawm lub teeb load pib-up, lub ntsiab tswj Circuit Court yog txuas nrog lub hwj chim mov, thiab lub RUN cov ntaub ntawv teeb liab yog kev cob cog rua nyias, yog li ntawd lub roj teeb nqi resistor tau yooj yim raug hlawv tawm raws li tam sim no thiab lub load inverter tam sim no. Nws qhov kev puas tsuaj feem ntau tshwm sim los ntawm kev puas tsuaj, blackening ntawm lub plhaub, tawg, thiab lwm yam cim ntawm kev puas tsuaj. Nws kuj tseem tuaj yeem ntsuas qhov tsis kam raws li multimeter (rau cov cuab yeej muaj peev xwm sib txawv, tus nqi kuj txawv, koj tuaj yeem xa mus rau tus nqi tsis kam ntawm tib tus qauv)
