Nws txais yuav cov khoom siv hluav taws xob siab tshaj plaws thiab kev hloov dua siab tshiab rau hauv nruab nrab ntawm 24V DC stabilized fais fab mov rau txhua chav ntsuas.
Txheej txheem cej luam ntawm switching power supply box
Lub thawv yog ib qho ntawm cov pab pawg ntawm cov cuab yeej ua ke ntawm lub tshuab hluav taws xob. Nws yog ib qho tshiab 24V DC tswj fais fab mov uas lub hauv paus muab lub zog rau txhua chav tsev ntsuas, thiab siv cov khoom siv hluav taws xob siab tshaj plaws thiab kev siv tshuab hloov pauv. cov ntsiab lus raws li hauv qab no:
Cov tswv yim dav AC ntau, kev ua haujlwm siab, lub teeb yuag, cov khoom siv digital, cov khoom siv ruaj khov, kev nyab xeeb thiab txhim khu kev qha, tsis muaj kev cuam tshuam lub zog zaus suab nrov ntawm cov khoom siv hluav taws xob qub. Nrog cov zis overvoltage, undervoltage, overcurrent, luv luv Circuit Court tag nrho lav muaj nuj nqi. Thaum ib qho tsis ua hauj lwm tshwm sim, qhov tso zis hluav taws xob yuav raug tso tseg thiab lub tswb yuav raug muab tawm, thiab cov khoom siv hluav taws xob thaub qab yuav raug txuas nrog kom ntseeg tau tias lub zog ib txwm muaj ntawm tag nrho lub cev. Nws tau txais cov thoob ntiaj teb nrov European-style davhlau ya nyob twg thaiv tsis muaj kev saib xyuas, muaj zog xauv, kev ua haujlwm yooj yim thiab kev nyab xeeb hluav taws xob siab, thiab tau nruab nrog ntau yam ntawm DC24V outputs. Nws muaj lub luag haujlwm ntawm kev lees paub cov khoom siv hluav taws xob sab nraud. Thaum lub thawv fais fab tsis ua haujlwm, nws tuaj yeem txiav tawm cov khoom siv hluav taws xob sab nraud, thiab tsis muaj qhov hluav taws xob tso tawm kom ntseeg tau qhov ntsuas qhov system. Thiab muaj qhov chaw tiv tauj sab nraud ntawm ALARMOUT rau lub tswb nrov thiab lub teeb.

Txoj cai ntawm switching power supply box
Lub switching stabilized fais fab mov lub thawv yog tsim los ntawm tsib qhov yooj yim modules. AC input kab yog rectified thiab lim los ntawm ib tug module, thiab lub high-frequency converter yuav nqis los thiab tso zis, thiab lwm yam module yuav ntxiv rectify thiab lim cov zis. Qhov tseeb ntawm qhov tso zis hluav taws xob yog ua tiav los ntawm kev tswj xyuas Circuit Court, uas xa rov qab cov zis rau lub converter los tsim ib lub voj kaw. Thaum lub load hloov los yog qhov input voltage fluctuation ua rau cov zis voltage hloov, lub voj tswj rhiab heev pom qhov hloov me ntsis ntawm cov zis voltage, thiab cia li xa cov teeb liab coj mus rau lub converter. Lub pulse tawm tswv yim kho cov teeb liab kom cov zis voltage ntawm tus thawj lub xeev, yog li stabilizing lub voltage tso zis.
Rau qee qhov laj thawj, thaum cov zis hluav taws xob ntau tshaj 26V lossis qis dua 22V, qhov kev tiv thaiv pib lub relay tam sim ntawd, txuas cov khoom siv hluav taws xob rov qab thiab xa tawm lub tswb nrov. Thaum lub load (ua hauj lwm ntsuas) tsis ua hauj lwm thiab tsim ib tug luv luv Circuit Court, kev tiv thaiv system yuav cia li kaw cov zis kom tsis txhob muaj xwm txheej loj.
Kev siv lub tshuab hluav taws xob hloov hluav taws xob
1. Cov tswv yim
Voltage: Cov lus qhia voltage input yuav tsum ua raws li qhov ntau yam cim ntawm lub thawv hloov hluav taws xob.
Lub zog tseem ceeb: Lub zog tseem ceeb ntawm kev hloov pauv hluav taws xob dav dav yog {{0}}}.6, thiab kev hloov hluav taws xob tswj hluav taws xob nrog AF nquag lim tuaj yeem ncav cuag 0.99, yog li nws yuav tsum tau them sai sai rau thaum xaim.
Grounding: Txij li thaum hloov hluav taws xob hloov hluav taws xob muaj lub lim EMI, lub tshuab hluav taws xob hauv av ntawm lub plhaub hluav taws xob yuav tsum txuas nrog lub ntiaj teb nrog cov hlau tuab thiab luv.
Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum siv ntau chav nyob kom ntseeg tau tias kev siv nyab xeeb.
2. Tso zis
Cov zis hluav taws xob: Nws yuav tsum nyob rau hauv qhov ntsuas qhov ntsuas, thiab kev saib xyuas yuav tsum tau them rau kev sib raug zoo ntawm qhov kub thiab txias thiab cov zis derating.
3. Kev ua neej nyob
Lub neej ntawm kev hloov hluav taws xob muab faib ua peb theem.
Thawj theem tsis ua hauj lwm: Txhawm rau tiv thaiv kev ua tsis tiav thawj zaug, cov khoom tsis zoo tau raug tshuaj xyuas ua ntej kev teeb tsa. Ua ntej tawm hauv lub Hoobkas, nws tau dhau qhov kev thauj khoom puv 72- teev kev laus. Yog li ntawd, feem ntau ntawm cov khoom tau nkag mus rau theem ntawm qee zaus tsis ua haujlwm thaum lawv xa mus rau cov neeg siv khoom.
Qee lub sij hawm tsis ua hauj lwm theem: qhov ruaj khov ntawm txhua qhov tsis ua haujlwm yog cuam tshuam nrog nws lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF), qhov tseem ceeb ntawm qhov tsis ua haujlwm yog tsawg heev. Txawm li cas los xij, tus nqi tsis ua haujlwm nyob rau qee lub sijhawm tsis ua haujlwm yog cuam tshuam nrog tus neeg siv kev teeb tsa thiab kev ua haujlwm (ambient kub, derating, qhov cua, vibration).
Wearout tsis ua hauj lwm theem: Tom qab lub sij hawm tsis ua hauj lwm tsis ua hauj lwm, lub hwj huam mov nkag mus rau lub wearout tsis ua hauj lwm theem.
ambient kub thiab lub neej: Txij li thaum lub switching fais fab mov ua hauj lwm nyob rau hauv lub siab zaus thiab siab zog tej yam kev mob, lub neej ntawm ntau yam khoom siv yog ze ze rau qhov kub thiab txias, xws li electrolytic capacitors, kiv cua, thiab lwm yam kev sib raug zoo ntawm lub neej ntawm electrolytic capacitor thiab lub ambient kub yog: yog hais tias lub ambient kub nce los ntawm 10 degree, lub neej yuav halved; ntawm qhov tsis sib xws, yog tias qhov ntsuas kub ntawm qhov nruab nrab raug txo los ntawm 10 degree, lub neej yuav raug muab faib ua ob npaug.
