Cov txheej txheem kev khiav hauj lwm rau kev txhim kho thiab siv UPS fais fab mov

Vim yog qhov tshwj xeeb ntawm nws cov inverter thiab roj teeb ua haujlwm, kev teeb tsa thiab kev siv UPS lub zog yuav tsum muaj cov txheej txheem kev ua haujlwm nruj thiab kev tshawb fawb txhawm rau txhim kho kev ua haujlwm ruaj khov, txo cov khoom siv tsis ua haujlwm, thiab ua tiav cov khoom siv hluav taws xob tsis muaj kev cuam tshuam. khoom siv.

(1) Kev teeb tsa ib puag ncig ntawm UPS fais fab mov yuav tsum tsis txhob muaj lub hnub ci ncaj qha thiab tawm qhov cua kom txaus kom tswj tau qhov kub ntawm qhov chaw ua haujlwm tsis siab tshaj 25 degree. Yog tias qhov chaw ua haujlwm kub siab tshaj 25 degree, txhua txhua 10 degree qhov kub thiab txias yuav ua rau lub roj teeb luv luv li ntawm ib nrab.

(2) Nws tsis pom zoo kom siv lub zog thyristor loads, thyristor choj rectifiers, los yog ib nrab nthwv dej rectifiers ntawm qhov tso zis kawg ntawm UPS fais fab mov, vim hais tias cov loads tau yooj yim ua rau qhov kawg tsav transistor ntawm lub inverter raug hlawv. .

(3) Ua raws li qhov tseeb pib thiab kaw cov kab ke kom tsis txhob muaj qhov hloov pauv loj hauv qhov tso zis hluav taws xob ntawm UPS lub zog hluav taws xob thaum lub load dheev nce lossis txo qis, uas tuaj yeem ua rau UPS lub zog ua haujlwm tsis zoo.

(4) Nws yog txwv tsis pub nquag tua thiab qhib lub zog UPS. Feem ntau, nws yuav tsum tau tos tsawg kawg 30 vib nas this tom qab kaw lub hwj chim UPS ua ntej qhib lub hwj chim UPS. Yog vim li cas rau qhov kev ua txhaum ntau zaus hauv cov khoom siv me me thiab nruab nrab UPS yog cov neeg siv nquag qhib lossis tawm, thiab UPS fais fab mov hloov pauv ntawm inverter fais fab mov thiab bypass fais fab mov nrog load.

(5) Kev xyaum tau ua pov thawj tias rau feem ntau ntawm UPS cov khoom siv hluav taws xob, tswj lawv cov khoom thauj hauv thaj tsam ntawm 50 feem pua ​​​​rau 60 feem pua ​​​​ntawm cov khoom siv hluav taws xob yog qhov ua haujlwm zoo tshaj plaws. Kev txwv tsis pub tshaj. Cov chaw tsim khoom qhia tias qhov siab tshaj plaws pib load ntawm UPS fais fab mov yuav tsum tswj tsis pub dhau 80 feem pua. Yog tias overloaded, lub inverter transistor feem ntau yuav tawg hauv lub xeev inverter. Nws tsis raug nquahu kom ua haujlwm nrog lub teeb ci ntau dhau, vim qhov xwm txheej no tuaj yeem ua rau lub roj teeb tsis ua haujlwm tau yooj yim vim tias cov roj teeb tawm tam sim no tsawg.

(6) Tsis tu ncua tswj UPS fais fab mov: saib xyuas cov xwm txheej ntawm lub teeb pom kev ua haujlwm, tshem tawm cov plua plav, ntsuas roj teeb hluav taws xob, hloov cov roj teeb uas tsis tsim nyog, xyuas cov haujlwm ntawm lub kiv cua, thiab kuaj xyuas thiab kho qhov system tsis ua haujlwm ntawm UPS.

(7) UPS fais fab mov yog tsim nyog rau nqa micro capacitive loads, tab sis tsis yog rau nyob inductive loads xws li cua txias, motors, xyaum, kiv cua, thiab lwm yam. Yog hais tias UPS lub hwj chim load yog resistive los yog inductive, nws yog tsim nyog los txo nws. load raws li tsim nyog kom tsis txhob overloading.
