Tham txog qee cov teeb meem ntawm cov khoom tiv thaiv kom tsis txhob raug mob (SPDs)
1. Qee qhov teeb meem ntawm "OBO style qauv"
Suav cov khoom tiv thaiv kab mob tiv thaiv (SPDs) huab hwm coj-ntau lawm raws li Dehn, OBO, thiab Citel tus qauv tsim. Txawm li cas los xij, nrog kev txhim kho ntawm cov thev naus laus zis thiab kev coj ua, kev tsub zuj zuj ntawm cov khoom tiav yog hloov tas li, xws li Dehn, Phoenix, Raycap, OBO, Citel, Hakel, Saltek surge tiv thaiv, ib txwm khaws ua ntu tshiab thiab qauv. Cov kev hloov pauv no tsis tsuas yog ua qee yam kev hloov pauv, muaj qhov sib txawv, tab sis muaj ntau tus qauv thiab ua haujlwm ntawm qhov ua kom zoo dua. Tab sis saib ntawm feem ntau ntawm Tuam Tshoj SPDs cov chaw ua haujlwm, lawv tseem siv qhov qauv tsim kho tsis xws li OBO cov qauv:
1.1 Cov luv tiv thaiv tiv thaiv kab mob qauv
Ua ntej ua qhov loj paug tam sim no kuaj
Tom qab kuaj, nyam ua ke ntawm lub paug tawm tam sim no.
Cov lus hais: Yuav kom ua tau raws li qhov sib txuam ntawm xob laim tam sim no kho tshuab, txo qhov chaw hla ntu ntawm cov neeg tuaj yeem tuaj yeem txhim kho qhov muaj peev xwm tiv thaiv luv luv ntawm kev tiv thaiv, tab sis xav paub kom meej tias kev tawm tam sim no thiab luv-Circuit Court fusing yog qhov teeb meem tsis sib haum, nws xav tau ntau qhov kev sim, tsis yog dig muag txo qhov chaw hla ntu thaj chaw ntawm cov neeg sib tiv.
1.2 Txheej ntawm kab
Muaj qhov tsis zoo tsim nyob rau hauv OBO cov qauv, tripping mechanism, thiab MOV nyob rau hauv tib chav, nws txhais tau tias muaj cov xov tooj hluav taws xob siab thiab cov xov tooj hluav taws xob tsawg nyob hauv tib chav.
(tooj liab braid snap; solder melting)
Raws li lub hauv paus ntsiab lus ntawm electromagnetism, Tib Qhov kev taw qhia tam sim no nyiam sib, raws li qhia saum toj no, thaum tooj liab braid me ntsis ntev dua, nws yuav nyiam ntawm tus neeg xyuas pib ntawm tib qho kev coj tam sim no thiab tus neeg xyuas pib ntawm kev coj rov qab tam sim no, vim tooj liab braid yog knitting thiab muaj lub peev xwm ntawm ncab, nws ua kom tshwm sim ntawm saum toj no
1.3 Vuam tsis muaj zog ntawm cov tooj liab tooj liab thiab cov tooj liab
Cov qauv ntawm OBO cov qauv, muaj ntau qhov chaw ua si ntawm txoj haujlwm no, nws yooj yim rub tawm cov kab tom qab qhov cuam tshuam tawm tam sim no, lub vuam yooj yim rau kev txiav.
1.4 Lub tiaj ntsuab yas yog yooj yim rau kev puas tsuaj
Qhov chaw hais tau zoo ntawm lub tiaj yas ntsuab yog ib qho yooj yim poob qis, liab qhia ntawm lub qhov rais pom, nws ua kom tsis raug (ua txhaum). Nws ua rau los ntawm tib lub laj thawj li hais saum toj saud 3.
1.5 Qhov kev ncua deb ntawm kev tso poj niam tawm yog nqaim
Solder tin me ntsis ntxiv, tiv thaiv kub dhau yuav tsis muaj peev xwm tso tau txhua yam. Qhov kev ncua deb ntawm kev tso tripping yog tsawg dua 5 hli hauv no OBO cov qauv kev ua qauv, SPD cov tuam txhab tsim khoom yuav tsum them sai sai rau nws.
Ib qho ntxiv, theej tawm cov hnub qub dhau los ntawm DEHN tus qauv tso tawm
MOV thiab ntsaws tawm qhov system tso rau hauv chav sib txawv, qhov kev ncua deb ntawm tripping tso tawm yog kwv yees. 10mm, lub thawv yas tsis cuam tshuam los ntawm electrodynamic quab yuam.
Qhia DEHN tus qauv tso tawm
Tam sim no Raycap tus ntaiv tso qauv
Tam sim no Phoenix kev qhia tso tawm qauv
Tam sim no OBO's tripping tso qauv
Cov teeb meem tsis quav ntsej txog IP20 tiv thaiv cov khoom tiv thaiv
Ntau xyoo dhau los, SPDs kuaj saib xyuas cov hluav taws xob muaj hluav taws xob, muaj kev tso tawm tam sim no, kev hloov pauv overvoltage (TOV), thermal stability, ntau cov pulses, tab sis tsis quav ntsej qhov ntsuas qhov yooj yim ntawm cov khoom siv hluav taws xob tsawg.
Hauv ib nrab xyoo, SPD kuaj chav kuaj pom ntau SPD tsis tsim nyog IP20 chav kawm, qhov teeb meem no feem ntau tshwm sim hauv OBO cov qauv puag qub, hu rau Suav SPD cov chaw lag luam tsis tsim nws ntxiv lawm, muaj ntau yam teeb meem thiab qauv teeb meem hauv OBO style SPD qub. Cov.
Dab tsi yog qhov txhais tau ntawm IP20?
Tus lej '2' txhais tau hais tias tiv thaiv 12mm cov khoom (xws li ntiv tes loj) nkag, siv cov ntiv tes sim rau kev siv tau.
Tus lej '0' txhais tau tias qib ua tsis tau dej.
Tsis txhob xav tias tsis muaj teeb meem hauv koj cov khoom lag luam, kev tshuaj xyuas qhov muag pom tau zoo li kev txiav txim siab.
Sab laug thaij duab: qhov tsim nyog, saum npoo ntawm cov ntsia hlau tau ntev txog 1.5 hli
Kev yees duab: tsis tsim nyog
Thaum zawm thiab khi, qhov chaw ua haujlwm ntawm lub hau ntswj yuav tsum tsis hloov pauv.
Cov xwm txheej ntawm nruj
Tom qab kuaj xyuas, nyob rau hauv qhov xwm txheej ntawm SPD cov tsev nyob tsis muaj qhov sib txawv, nrhiav IP20 tsis muaj qhov ntsuas tsis tsim nyog txawm tias yuav tsum nruab rau hauv lub tsev tsim nyog.
Raws li kev yees duab saum toj, sab laug duab: tsis raug, ntsia hlau tsim nyog, txoj cai yees duab: kov, ntsia hlau tsis tsim nyog
Tom qab ntsuas, qhov tshwj xeeb ntawm lub ntsia hlau yog sib xws, Cov teeb meem tshwm sim hauv cov qauv ntawm cov hlau.
Qhov saum npoo ntawm cov ntsia hlau yog tsis sib xws thaum ntsia ntawm cov qauv ntawm cov hlau.
thiab pom muaj qhov sib txawv hauv cov qauv duab.
Yog tias xav ua kom tau raws li qhov yuav tsum tau ua ntawm chav kawm IP20, qhov loj ntawm cov qauv hlau yuav tsum tsawg dua 2 cm.
lossis siv cov npog davhlau ya nyob twg, yam tsis muaj kev kuaj.
