Txawm hais tias qhov muag teev "thaum ub" Ilyich tau hloov los ntawm kev lag luam ntau dua - diode thiab lwm yam analogues, qhov muag teev tseem tseem nrov thiab xav tau ntawm cov neeg siv khoom niaj hnub no. Cov khoom no muaj ob qho tib si pros thiab cons. Ib qho nrov tshaj plaws yog 200W incandescent teeb. Yog vim li cas qhov no tshwm sim, cia peb sim ua kom pom hauv kab lus no.

Lub teeb yog dab tsi?

Feem ntau ntawm sab hauv ntawm 200W incandescent teeb tuaj yeem pom los ntawm nws lub teeb pob tshab. Cov khoom tseem ceeb ntawm cov cuab yeej yog cov electrodes uas pub ib cov xov ntawm refractory tungsten hlau stretched ntawm lawv. Yog li hais tias cov fragile tungsten filament tsis tawg thaum thauj cov cuab yeej, nws tau txais kev txhawb nqa los ntawm cov tuav (txhawb) ua los ntawm molybdenum. Tag nrho cov electrodes thiab tuav converge mus rau nruab nrab thiab mus rau lub hauv paus, qhov uas lawv interlocked nrog bimetallic hlau thiab soldered rau hauv ib lub iav ncej txuas mus rau lub hauv paus.

Ntxiv mus peb tsis tuaj yeem pom qab lub hauv paus npog, tab sis tsis muaj dab tsinthuav thiab tej yam yees siv muaj. Qhov ntxiv yog cov zis thiab energized nrog nruab nrab kev sib cuag soldering, qhov rho tawm kev sib cuag nrog lub voj voog ntawm lub hauv paus, ua nyob rau hauv daim ntawv ntawm ib tug xov kom lub teeb yuav tsum screwed rau hauv lub qhov (socket).

Txoj Cai Ua Haujlwm

Lub 200 W incandescent teeb ua haujlwm zoo li txhua yam khoom siv uas tau ua kom sov los ntawm cov teeb pom kev zoo. Lawv yog cov hlau, cua sov, cov tshuab plaub hau, soldering irons thiab lwm yam khoom siv. Nyob ntawd, hlau lwm yam nyob rau hauv muaj pes tsawg leeg yog siv rau cua sov, nrog rau theem ntawm kev ua hauj lwm yuav tsum tau. Tungsten, ntawm qhov tod tes, muaj qhov ua haujlwm siab heev. Nws yog nws uas tsis tso cai rau cov xov me me kom yaj thiab tawg thaum lub zog ntawm 220 volts siv rau nws. Nws tsuas yog ua kom sov txog li qhov uas nws tsuas yog tsis yooj yim sua kom saib nws nrog lub qhov muag liab qab rau lub sijhawm ntev. Nws yog qhov ci ntawm cov xov dawb-kub no uas tawm lub teeb piv rau ntau lub teeb taws tswm ciab.

Tungsten twists

Tab sis peb paub los ntawm cov lus qhia chemistry tias yog tias tungsten tau rhuab mus rau qhov kub ntawm 3000 degrees (qhov no yog qhov kub ntawm cov filament hauv cov khoom siv ua haujlwm), nws yuav yooj yim pib oxidize, vim qhov filament yuav tawg.. Yog li ntawd, nyob rau hauv lub puab kab noj hniav ntawm lub hwj ntawm 200 W incandescent teeb, raws li zoo raws li nyob rau hauv cov khoom zoo sib xws ntawm lwm yam kev ntsuam xyuas, txawm tsis muaj huab cua nyob rau hauv tag nrho cov (lub tshuab nqus tsev reigns), los yog nws yog hloov nyob rau hauv nws nrog ib tug inert roj, nrog molecules. uas tungsten tsis hnov mob thaum rhuab.

Pluss of incandescent qij

Qhov zoo tshaj plaws ntawm cov khoom siv hluav taws xob zoo li no yog:

• zoo heevtus nqi qis;
• muaj peev xwm ua haujlwm ib txwm nyob rau hauv ib qho kev hloov pauv ntawm qhov kub thiab txias atmospheric av;
• lub peev xwm ntawm lub teeb zoo li no los ua kom muaj cua sov, uas tseem ceeb rau qee qhov xwm txheej;
• muaj peev xwm tiv taus lub zog me me;
• tsis emit cov pa phem rau hauv qhov chaw thaum tawg;
• tsis xav tau kev ntsuas pov tseg tshwj xeeb.

Cons of incandescent qij

Lawv nyob ntawd thiab. Thiab qhov tsis zoo ntawm 200W incandescent teeb yog:

• Comparative fragility, txij li lub warranty ua hauj lwm lub neej ntawm xws li pab kiag li lawm yog txwv rau 1000 teev ntawm 220V thiab 2500 teev ntawm 127V.
• Ib lub khob fwj uas puas lawm los ntawm qhov cuam tshuam me ntsis ntawm txhua yam khoom tawv.
• Perceptibly ntau zog noj piv rau kev txuag hluav taws xob counterparts.

Zoo kawg

Muaj cov teeb taws teeb nrog E14 thiab E27 sockets. Tsis tas li ntawd, cov khoom sib txawv ntawm lub zog. Cov qauv nrov tshaj plaws yog 60, 100, 150 thiab 200 watts. Yuav ua li cas yuav, ib tug 60 W E27 incandescent teeb rau 20 rubles nrog ib tug kev pab ntawm 1000 teev, los yog nws diode counterpart, tus nqi ntawm uas ntau tshaj 2000 rubles, tab sis nrog ib tug peev txheej ntawm 40,000 teev? Qhov kev xaiv, dua, yog koj li!
