Raws li peb txhua tus paub, cov khoom siv kho qhov muag fiber ntau yog ib qho tseem ceeb ntawm kev sib txuas ntawm lub cev thiab lub rooj tswj hwm lub ntsiab, thiab ib zaug ib qho "optical fiber tsis ua hauj lwm" tshwm sim, kev sib txuas lus ntawm pawg tswj hwm thiab lub rooj tsav xwm tseem ceeb yuav cuam tshuam. Optical fiber yog lub paj hlwb ntawm lub inverter. Thaum cov fiber ntau optical tsis ua haujlwm, lub inverter yuav ua rau tuag tes tuag taw, uas yuav ua rau muaj kev puas tsuaj loj rau lub tsev tsim khoom. Yog li ntawd, thaum muaj teeb meem tsis ua hauj lwm, nws yuav tsum tau ua raws sijhawm thiab ua tib zoo saib xyuas.
Mus kom ze
Thaum muaj "fiber tsis ua haujlwm", cov haujlwm hauv qab no yuav tsum tau ua:
1. Xyuas seb lub hwj huam mov ntawm lub hwj chim module puas zoo li qub (thaum ib txwm muaj, lub teeb pom kev ntsuab L1 yog qhib);
2. Tshawb xyuas seb lub qhov muag fiber ntau txuas ntawm lub hwj chim module thiab tus maub los poob;
3. Txawm hais tias cov khoom siv kho qhov muag puas tawg lossis tawg;
4. Seb lub optical fiber yog dig muag los ntawm hmoov av;
5. Thaum lub rooj tswj hwm lub rooj tsav xwm thiab lub rooj tsav xwm kho qhov muag tau raug puas ntsoog, qhov kho qhov muag fiber ntau tau tshaj tawm;
6. Qee lub sij hawm lub inverter yuav qhia txog qhov teeb meem ntawm kev sib txuas lus hauv tsev kho qhov muag thaum lub hwj chim tawm, uas yog qhov tshwm sim ib txwm muaj thiab tuaj yeem rov pib dua ncaj qha.
Kev paub teb
1. Cov zis ntawm lub module fais fab mov (HAS5-5-W) ntawm lub rooj tsavxwm tswj chav tsev yog txawv txav los yog cov input terminals ntawm lwm lub hwj chim modules luv luv (nws yuav tshwm sim thaum lub hwj chim-on, standby, thiab khiav cov txheej txheem ntawm inverter).
2. Lub miniaturized optical fiber yog faulty; qhov ua rau muaj kev txhaum: kev tiv thaiv kev cuam tshuam kev ua haujlwm ntawm pawg tswj hwm pawg tswj hwm tsis zoo. Kev daws: nruab ib lub nplhaib sib nqus ntawm cov kab tsav.
3. Optical fiber tsis ua hauj lwm tshwm sim los ntawm discrete li;
Discrete Cheebtsam: CPLD, siv lead ua oscillator, optical fiber tuav (hauv lwm pawg)
Fault stage: Thaum lub cuab yeej siv hluav taws xob, qhov kev ua txhaum fiber ntau tuaj yeem raug tshaj tawm
Txheej txheem txheej txheem: hloov lub chav tswj hwm pawg tswj hwm qib ntawm qhov chaw.
4. Corrosion ntawm optical fiber ntau lub rooj;
Lub electrolytic capacitor ntawm lub module tau tawg, tab sis tsis muaj kev puas tsuaj rau cov qhab nia tsis kam, qee zaum kho qhov muag tsis ua haujlwm, thiab qee zaum tsav tsheb tsis ua haujlwm. Lub ntsiab feature: lub rooj zaum fiber ntau optical ntawm lub rooj tswj hwm lub rooj tsavxwm yog qhov muag plooj.
5. Optical fiber tsis ua hauj lwm los ntawm lwm yam.
Fault point:
(1) Lub me me transformer yog hlawv;
(2) Lub fuse yog xoob;
(3) Tus choj rectifier yog hluav taws kub;
(4) Optical fiber yog retracted;
(5) Lub electrolytic capacitor txau cov kua.
Fiber ceev faj
Lub vojvoog dabtsi yog khoov ntawm qhov sib txuas ntawm qhov sib txuas ntawm qhov muag thiab lub qhov muag fiber ntau yuav tsum tsis pub tsawg dua 30 hli, uas yog qhov tsawg kawg nkaus tso cai khoov vojvoog.
Tsis txhob siv lub zog rub ntawm 80N (8.2kgf) lossis ntau dua rau cov fiber ntau optic cable. Txawm tias ib ntus tawm ntawm lub zog rub tawm tuaj yeem ua rau muaj kev puas tsuaj mus tas li rau cov fiber ntau.
Tsis txhob twist fiber optic cables.
Thaum txuas cov fiber ntau optical cable, ua tib zoo saib tias cov khoom siv kho qhov muag yuav tsum tau muab tso rau hauv lub qhov (socket) kho qhov muag vertically, thiab yuav tsum tsis muaj lub kaum sab xis. Tsis tas li ntawd, thaum lub optical connector txuas nrog, tag nrho cov xiav thiab grey yuav tsum tau muab tso rau hauv lub qhov (socket) kho qhov muag.
Thaum lub sij hawm installation, nws yog ib qho tsim nyog yuav tsum tsis txhob muaj qhov xwm txheej uas yuav ua rau kev sib tw ntawm fiber ntau optic cable.
