Puas muaj cov lus qhia txog kev siv Dummy Load nrog cov Transmitters?

"Txawm hais tias koj yog tus kws tshaj lij RF tus kws tshaj lij lossis tus neeg nyiam xov tooj cua, nws feem ntau lees paub tias: Yog tias koj xav ua RF xeem ntawm FM xov tooj cua transmitter yam tsis siv FM tshaj tawm xov tooj cua, ces siv RF dummy load."

----- Ray Chan, ib tug neeg ua haujlwm ntawm FMUSER

Tos, dab tsi ntawm transmitter koj tuaj yeem siv lub dummy load nrog? Ok, qhov lus zais no yuav tsum tsis txhob hais nws yooj yim tab sis nws yuav muaj txiaj ntsig rau koj: Thaum lub zog ntawm dummy load thiab FM transmitter zoo ib yam, lub zog loj dua lub dummy load, ntau lub tshuab xa hluav taws xob sib txawv siv tau, hauv ib txoj kev, nws txhais tau tias yog tias koj muaj 50kw dummy load, koj tuaj yeem siv cov khoom xa tawm nrog lub zog qis dua 50kw (50 watt, 500 watt, 600 watt, 1kw, 2kw, 2.5kw, 3kw, 4kw, 5kw, 10kw, 20kw, thiab lwm yam); Thaum koj muaj lub dummy load uas lub hwj chim mus txog 200KW, koj tuaj yeem siv ntau lub FM transmitters ntawm txhua yam ntawm lub zog ranged.

Tau kawg, koj tuaj yeem siv lub dummy load nrog rau yuav luag tag nrho FM tshaj tawm xov tooj cua ntawm txhua lub zog, peb tau tsim cov khoom hauv qab no ntawm FM xov tooj cua transmitters: 500W, 600W, 700W, 1000W, 1200W, 1500W, 2000W, 2500W, 3000W, 3500W, 5000W, 6000W, 7000W, 10000W, 15000W, 20000W, 30000W, 40000W, 50000W, 60000W, 70000W, 80000W, 1000 watt, 1200 watt, 1500 watt, 2000 watt, 2500 watt, 3000 watt, 3500 watt, 5000 6000 watt, 7000 watt, 10000 watt, 15000 watt, 20000 watt, 30000 watt, 40000 watt, 50000 watt, 60000 watt, 70000KW 80000W, 1KW 2KW, 3.5KW, 5W 4KW, 5.3KW, 5.4KW, 8KW, 10KW, 15KW, 18KW, 20KW, 22.5KW, 25KW, 30KW, 35KW, 40KW, 45KW, 46.4KW 50KW, 50.7KW , 55kw, 65kw, 75kw, 80kw, 100kw, 130kw, 150kw, thiab ntau lub zog ntau dua ntawm FM transmitters. 

Vim li cas thiaj xaiv 50KW RF Dummy Load rau FM Xov Tooj Cua?

Koj Xav Tau Zoo 50kW RF Dummy Load

Ntxiv nrog rau kev tso cai rau koj kom raug kho qhov tsis zoo ntawm lub transmitter thiab receiver, lub dummy load tseem tuaj yeem tiv thaiv kev puas tsuaj rau lub cuab yeej los ntawm kev ua haujlwm tsis raug. Cov kws tshaj lij RF engineers txhua tus paub tias dummy load yog ib qho cuab yeej rau cov khoom siv thauj khoom los kuaj ntawm lub tshuab hluav taws xob lossis RF system.

Yog tias koj siv lub kav hlau txais xov ncaj qha es tsis txhob muaj kev thauj khoom thaum lub sijhawm kuaj, tsis yog koj tuaj yeem kho tsis tau zoo, cov cua sov uas tsim los ntawm RF fais fab yuav ua rau koj lub transmitter lossis receiver puas. Lub dummy load tuaj yeem simulated tus kav hlau txais xov zoo kawg nkaus txuas nrog lub tshuab hluav taws xob tuaj yeem zam qhov teeb meem tsis raug lossis kev puas tsuaj ntawm cov khoom siv RF.

Yog li ntawd, peb xav kom koj xaiv ib tug txhim khu kev qha dummy load thiab siv nws raws sij hawm thiab kom raug thaum kuaj RF cov cuab yeej kom tsis txhob tsis tsim nyog poob.

Koj tuaj yeem ntseeg tag nrho cov Rack 50KW RF Dummy Load, ib yam li koj ntseeg hauv FMUSER.

FMUSER 50KW RF Termination ua haujlwm li cas?

Nyob rau hauv tus txheej txheem ntawm RF system kuaj, 50kw dummy load (tseem hu ua 50000w dummy kav hlau txais xov) ua raws li qhov tseeb "antenna". Nws yog siv los simulate lub load ntawm cov khoom siv hluav taws xob, uas txuas nrog cov zis ntawm lub xov tooj cua transmitter. Nws tuaj yeem siv los kuaj thiab teeb tsa lub transmitter lossis receiver yam tsis muaj xov tooj cua tsis muaj zog. Ib qho 50kw dummy load feem ntau muaj cov resistor txuas nrog lub radiator uas dissipates lub zog los ntawm transmitter.

Lub 50000 watt dummy load yog siv los dissipate RF zog. Nws yog tus cwj pwm los ntawm 50 Ω impedance, thiab VSWR tsis ntau tshaj 1.20: 1. Yog li ntawd, vim tsis tshua muaj kev cuam tshuam coefficient, nws muaj txiaj ntsig zoo rau:

• kev saib xyuas ntawm FM xov tooj cua transmitter thiab tv transmitter
• lub load tawm ntawm RF lim
• qhov kawg ua tiav ntawm lub zog synthesizer. 

Nco ntsoov: Cov khoom sib txuas rau cov khoom siv no tuaj yeem hloov tau los ntawm n-hom fast connector rau lwm cov qauv yooj yim.

Yam Uas Koj Yuav Tsum Paub Txog

Thaum lub load yog powered on, ntswj tawm lub qhov cua ntawm lub pa valve. Txhawm rau tshem tawm, vim qhov nce ntawm dummy load kub, load chamber, rhuab expansion ntawm huab cua. Yog tias cov cua kub tsis raug tshem tawm hauv lub sijhawm, lub siab nyob rau hauv lub chamber yuav nce, kom lub siab ntawm lub gasket siab dhau lawm, thiab cov roj to ntawm lub qhov hluav taws xob loading yuav tshwm sim. Qhov chaw txaus (tsawg kawg 12 ntiv tes nyob ib puag ncig thiab sab saum toj) nyob ib puag ncig ntawm lub nra kom tso cai rau huab cua ncig thiab ua kom yooj yim dua rau cov cua sov rau lub dummy load

Yam Uas Koj Yuav Tsum Paub Txog

Nco ntsoov: Tus nqi thauj khoom tau kwv yees kwv yees, thov nrog peb tham txog kev thauj khoom ua ntej tso qhov kev txiav txim. 

• Ntxuam los ua ke ntawm 50KW RF Dummy Load

Thaum tawm hauv lub Hoobkas, cov xaim hluav taws xob ntawm cov khoom siv kiv cua tau raug teeb tsa, thiab tsis tas yuav muaj kev sib txuas tshwj xeeb. Cov kiv cua yuav tsum tau ua manually tshwj tsis yog tias cov khoom siv txuas nrog kev ua haujlwm tsis siv neeg hauv lub hoobkas. Yog tias lub kiv cua tsis tau pib, lub zog ntxiv rau qhov tsis raug load yuav tsum tsis txhob siab tshaj 1250W (tsim rau 5kW thiab 10kW load nrog cua txias).

• Transmitter Interlock ntawm RF Dummy Load Rack

Muaj kev cuam tshuam ntawm 1 thiab 2 tus pins ntawm peb lub qhov (socket), ib txwm kaw qhov hluav taws xob hloov pauv (cksd301 250V 10A 60 ℃) txuas nrog lub transmitter. Yog tias qhov txias txias ntawm qhov khoom tsis raug siab dhau lawm, qhov tsis tseeb load yuav raug puas tsuaj, qhov hloov pauv no yuav qhib thiab tawm ntawm lub transmitter.

• Kev Kho ntawm RF Dummy Load Rack

Yuav luag tsis muaj kev saib xyuas yuav tsum tau ua, tab sis nws yuav tsum tau ua kom lub tshuab kom huv si thiab muaj plua plav pov thawj. Kev hloov teb ntawm cov resistors tsis pom zoo. Txawm li cas los xij, yog tias tsim nyog, zawm lub tshuab ua pa thiab tso lub tshuab vertically nrog RF connector tig mus.

Tshem tawm lub qhov (socket head screws) ntawm 8 qhov chaw ruaj khov RF. Ua tib zoo thiab ceev nrooj nqa lub rooj sib txoos kom cov roj ntau dhau rov qab mus rau lub tshuab hluav taws xob. Tso cov clip rau ntawm qhov kawg ntawm lub hau thiab tshem tawm 6 tapered taub hau screws. Ua tib zoo rub lub hau ntawm lub resistor. Txhawm rau nruab ib lub resistor tshiab, ua raws li cov kauj ruam rov qab, tab sis nco ntsoov tias tus resistor haum zoo kawg nkaus nrog lub fixture yam xyuam xim.

Tshawb xyuas O-ring ntawm lub radiator thiab RF sib dhos. Yog tias muaj qhov tawg lossis puas tsuaj, nws yuav tsum tau hloov tam sim ntawd. Tom qab txiav txim siab tias lub rooj sib txoos yog nyob rau hauv lub radiator, rov qab mus rau txoj hauj lwm kab rov tav thiab xyuas seb cov coolant to.

• Cov lus qhia kom txias ntawm 50KW RF Dummy Load

Nyob rau hauv lub Hoobkas, cov khoom cuav raug txhaj rau ntawm qhov kub thiab txias, nrog rau qhov tshwj xeeb uas tsis muaj tshuaj lom thiab tsis muaj hluav taws xob, thiab ncav cuag lub dav hlau qub. Saib xyuas lub coolant rau cov dej ntws. Ib qho me me ntawm cov dej xau yuav tsis cuam tshuam rau kev ua haujlwm, tab sis qhov xau yog loj, uas yuav muaj kev cuam tshuam tsis zoo. Yog tias tsis muaj qhov xwm txheej, tsis txhob hloov lub coolant, thov siv lub coolant los ntawm lub Hoobkas thawj. Qhov tshwj xeeb hluav taws xob thiab qhov kub thiab txias yam ntxwv ntawm lub coolant yog ib qho tseem ceeb heev rau lub nruam thiab ib txwm ua hauj lwm resistor.
