Nqe Lus Nug 1: Thaum muaj lub sijhawm hauv nroog, UPS cov zis yog qhov qub, thiab lub buzzer ntev ntev thaum tsis muaj kev lag luam, tsis muaj cov khoom tso tawm. Fault Analysis: Los ntawm qhov tshwm sim, nws tau txiav txim siab tias lub roj teeb thiab lub inverter ib feem ntawm qhov kev ua txhaum tuaj yeem raug tshuaj xyuas: Circuit Court tsis ua haujlwm. ----.

---- Yog hais tias lub inverter tsav Circuit Court tsis ua hauj lwm zoo, xyuas tias lub waveform muaj ib tug Circuit Court tsis muaj PWM tswj teeb liab tso zis. Yog hais tias muaj kev tswj cov teeb liab tso zis, qhov txhaum yog nyob rau hauv lub inverter tsav Circuit Court. ---- Yog tias lub waveform tsis muaj PWM tswj cov teeb liab tso tawm, xyuas seb nws cov zis puas raug thaiv vim muaj kev tiv thaiv Circuit Court, yog tias muaj kev tiv thaiv vim li cas; ---- Yog hais tias qhov kev tiv thaiv Circuit Court tsis ua hauj lwm, qhov kev khiav hauj lwm voltage yog ib txwm, thiab lub waveform tsis muaj PWM waveform tawm ntawm lub Circuit Court, qhia tias lub waveform yog corrupted ---- Qhov kev txiav txim ntawm cov saum toj no tribute kuj muaj peev xwm, tej zaum nws yuav nrhiav tau sai dua.

Nqe Lus Nug 2: Lub roj teeb hluav taws xob tsawg, tab sis qhov kev them nyiaj khau raj ntau tshaj kaum teev, lub roj teeb voltage tseem tsis tuaj yeem sau. Kev soj ntsuam yuam kev: Kev txiav txim siab los ntawm qhov tshwm sim raws li lub roj teeb lossis kev them nqi hluav taws xob tsis ua haujlwm, nws tuaj yeem kuaj xyuas raws li hauv qab no: - Tshawb xyuas seb cov khoom siv hluav taws xob thiab cov zis hluav taws xob ntawm lub them hluav taws xob puas zoo li qub; - Yog hais tias lub charger circuit input yog ib txwm, qhov tso zis tsis zoo li qub, disconnect lub roj teeb thiab ntsuas, yog tias tseem tsis zoo rau lub charger Circuit Court;. Nqe Lus Nug 3: Inverter fais fab theem khub ntawm lub hwj chim amplifier transistors, tom qab hloov tib lub qauv transistor, vim li cas rau kev khiav ib lub sij hawm ntawm lub sij hawm thiab kub kub yog heev loj, thiab qhov ua rau ntawm overcurrent tam sim no yog: - overcurrent tiv thaiv tsis ua hauj lwm.

Thaum lub inverter outputs ib tug overcurrent, lub overcurrent tiv thaiv Circuit Court yog tsis siv; - pulse width modulation (PWM) tivthaiv kev ua txhaum, qhov tso zis ob qhov sib txuas ua ke yog asymmetrical, ib qho yog nyob rau lub sijhawm, thaum lwm lub sijhawm luv, ua rau ob txhais caj npab tsis sib npaug, txawm tias ob txhais caj npab tig rau ib txhij, ua rau ob lub raj puas; - Lub hwj chim raj tsis muaj qhov loj, txawm tias lub symmetrical waveform yog input, cov zis yuav asymmetric, lub waveform yog output transformer, uas ua rau Gas magnetic, sib nqus flux yog unbalanced, accumulating lub transformer yuav saturated, tam sim no nce, burns phem lub hwj chim raj, thiab ib tug burning, lwm yam: UPS tsis muaj teeb meem tshwm sim. tsis ua haujlwm. Fault Analysis: Judging los ntawm qhov txhaum tshwm sim, nws qhov txhaum yog nyob rau hauv lub mains input, roj teeb thiab kev lag luam hluav taws xob kuaj Circuit Court: - Xyuas seb lub nroog cov hluav taws xob input fuse raug hlawv; - Yog tias lub lag luam tsis zoo, xyuas seb lub roj teeb pov hwm puas raug kuaj xyuas qhov kub hnyiab, vim qee qhov UPS yuav kaw tag nrho cov zis thiab tso saib ntawm UPS thaum lub roj teeb ntsuas tus kheej; Kev ua haujlwm hauv Circuit Court tsis ua haujlwm zoo thiab UPS tsis muaj kev ua lag luam tsis muaj kev ua lag luam, thiab UPS tseem yuav kaw tag nrho cov khoom tawm thiab tso tawm. - Yog tias lub nroog kuaj Circuit Court ua haujlwm tau zoo, xyuas seb lub roj teeb hluav taws xob ntsuas hluav taws xob puas zoo li qub.

Teeb meem 5: Nyob rau hauv cov ntaub ntawv ntawm kev nkag mus rau lub mains, txhua lub sij hawm lub UPS qhib, nws yuav hnov ​​lub relay ua hauj lwm suab, lub UPS vaj huam sib luag roj teeb voltage tsawg dhau, lub teeb ci thiab lub buzzer ntev. Raws li qhov tshwm sim txhaum cai saum toj no, nws tuaj yeem txiav txim siab tias qhov txhaum yog tias lub roj teeb voltage tsawg dhau, ua rau UPS pib ua tsis tiav. Tshem tawm lub roj teeb, ua ntej, sib npaug them (tag nrho cov roj teeb txuas nrog tib lub sijhawm), yog tias nws tseem ua tsis tiav, tsuas yog cov roj teeb hloov tau.

Nqe Lus Nug Rau: Ib qho UPS thaub qab ua haujlwm tau zoo, tsis muaj kev lag luam tawm, tab sis cov zis hluav taws xob tsawg, thiab lub tshuab hloov hluav taws xob muaj lub suab nrov. Fault Analysis: Inverter Output Description Qhov kawg-theem tsav Circuit Court yog ib txwm ib txwm, thiab lub transformer muaj suab nrov qhia tau hais tias ob txhais caj npab ntawm lub laub-rub Circuit Court yog asymmetric. Cov kauj ruam xeem yog raws li nram no: - Xyuas seb lub hwj chim puas zoo li qub; - Lub zog ib txwm, tom qab ntawd xyuas cov mem tes Wide output Circuit Court tso zis teeb liab yog qhov qub; - Yog hais tias lub pulse wide output Circuit Court outputs ib txwm, xyuas seb qhov tso zis ntawm tsav Circuit Court puas zoo li qub.

Nqe Lus Nug 7: Qhib UPS thaum lub zog hluav taws xob zoo li qub, qhov ntsuas hluav taws xob ua haujlwm inverter flashes, lub buzzer ua rau lub suab nrov nrov, thiab UPS tsuas tuaj yeem ua haujlwm hauv inverter, thiab tsis tuaj yeem hloov mus rau lub xeev tseem ceeb ntawm lub nroog. Fault Analysis: Inverter fais fab mov rau lub lag luam, qhia tias lub inverter fais fab mov tsis ua hauj lwm rau lub lag luam fais fab mov hloov dua siab tshiab seem, thiab nws yog tsim nyog los ntsuam xyuas seb lub cev muaj zog input fuse puas lawm; - Yog hais tias lub ntsiab input fuse tsis zoo, xyuas tias cov zis ntawm lub nroog hluav taws xob kwj dej lim Circuit Court yog ib txwm; Puas yog li qub?. Nqe Lus Nug 8: Thaum lub UPS thaub qab nyob ze rau tag nrho cov load, lub ntsiab fais fab mov yog ib txwm, thiab lub roj teeb fuse yog tshuab thaum lub roj teeb yog powered.

Kev Ntsuam Xyuas Tsis Zoo: Lub roj teeb fuse tshuab, qhia tias lub roj teeb tam sim no loj dhau, cov kauj ruam tshawb pom yog raws li hauv qab no: - Lub inverter tawg; - seb lub roj teeb voltage tsawg dhau; - Yog tias lub roj teeb voltage tsawg dhau, nws yuav pom tias lub roj teeb them hluav taws xob puas yog qhov qub. Yog tias lub roj teeb them hluav taws xob zoo li qub, kev ua haujlwm ntawm lub roj teeb hluav taws xob ntsuas hluav taws xob yog qhov qub. Nqe Lus Nug: UPS tsuas yog siv tau los ntawm lub ntsiab hluav taws xob thiab tsis tuaj yeem hloov mus rau lub zog inverter.

Fault Analysis: Tsis tuaj yeem ua lub lag luam-hluav taws xob inverter fais fab mov hloov dua siab tshiab, qhia tau hais tias lub nroog qhov hluav taws xob inverter fais fab mov hloov dua siab tshiab seem tau ua tsis tiav, thiab yuav tsum tau kuaj seb lub roj teeb voltage tsawg dhau, seb lub roj teeb fuse puas lawm; - Yog tias lub roj teeb zoo li qub, xyuas seb lub roj teeb hluav taws xob kuaj xyuas qhov hluav taws xob puas zoo li qub; Yog hais tias lub roj teeb hluav taws xob kuaj xyuas qhov hluav taws xob yog qhov qub, ces xyuas seb qhov kev lag luam-oriented inverter fais fab tuag tswj cov zis yog qhov qub.
