Ungayikhetha njani into yokukhusela isixhobo somenzi we-SPD
Amanqaku ama-8 abalulekileyo okuthenga isixhobo esikhuselekileyo sokukhusela esivela e-China
Thina LSP umenzi wase China ukusukela ngo-2010, sigxile kwimizamo yethu kuphuhliso lokhuselo lokuqhubela phambili nakwimveliso yezixhobo zokukhusela i-AC DC PV, sizama ukukhonza abathengi bethu ngeemveliso ezikumgangatho ophezulu.
Ukuba ungumngenisi wezixhobo zombane, umenzeli, umhambisi, umthengisi okanye umthengisi, xa uthenga i-AC kunye ne-DC okanye i-PV SPDs (izixhobo ezikhuselayo), kuya kufuneka wazi iingongoma ezi-8 ezibalulekileyo zokuthenga isixhobo esikhuselekileyo sokukhusela isixhobo (SPD) esivela e China
1. Izinto zokwenza imveliso
(1.1) Isinyithi seValist Varistor- MOV
Njengeyona nto iphambili ngaphakathi kwi-SPDs, ngaphandle kwesizathu, umgangatho we-SPD uxhomekeke ikakhulu kumgangatho we-varistors. Ngokucacileyo sebenzisa i-MOV esemgangathweni ebaluleke ngakumbi, zininzi izinto ezaziwayo zentsimbi ye-oxide varistors yokukhetha njenge-EPCOS / TDK, iLittelfuse, iKeko, iVarsi…

Ukuba ufuna uku-odola i-SLP40-275 / 4 (UC = 275Vac, IMAX = 40kA), nceda ubone itafile (siyichaza ebomvu), ikholamu Ubukhulu. Amandla ombane aqhubekayo (UC) - iVRMS (V), fumana idatha 275V, Siza kufumana imodeli I-CJA34S-431.
PS
CJ: kuthetha uphawu lweCJ.
A: kuthetha ukuba i-AC
34S: kuthetha isikwere sama-34mm
431: kuthetha ukuba i-varistor voltage yi-430V
Emva kokukhetha i-varistor ye-oxide yentsimbi (MOV), kusafuneka siqwalasele indlela yokuyibeka kwindlu ye-SPD. zimbini iindlela:
A.Ukugquma okusongelwe varistor, kuhlala kugqunywe ngombala oluhlaza okanye oluhlaza okwesibhakabhaka kobungqina bokufuma.
B. Abanye abenzi be-SPD basebenzisa i-varistor ehamba ze nge-contactor, kufuneka isebenzise i-epoxy resin ukungena. Kufuneka uyazi ukuba i-resin ye-epoxy ayisiyongxaki yokusingqongileyo, uphawu oludumileyo lwe-SPD alwenzi enye le nto.
C.Ukunciphisa iindleko, abanye abavelisi be-SPD basebenzisa i-varistor encinci ukubuyisela i-varistor ye-34S, masithathe umzekelo, ukuba ufuna ukuthenga ii-SPDs ezisemgangathweni, ndiyathemba ukuba ukukhutshwa kwangoku kwe-Nominal (8 / 20μs) Ku = 20kA kunye nokukhutshwa okuphezulu okwangoku (8 / 20μs) Imax = 40kA, kufuneka isebenzise i-34S varistor (34 ithetha 34mm; "S" ithetha isikwere), kodwa basebenzisa i-varistor encinci efana ne-20D, 25D, 32D ukubuyisela i-34S. Dwelisa ezi datha zobuchwephesha zalapha ngezantsi:

Uyilo lobume bangaphakathi
Zininzi kakhulu ii-SPDs zentengiso kwintengiso, uya kubona ukuba ubukhulu becala kuyilo lwesakhiwo sangaphakathi kuyilo lweemodyuli ezinokutsha: isitayile sikaDehn kunye nesimbo seOBO
Uhlobo lweOBO:
xa kuza ngoku ukubakho okukhulu, ububanzi beqhagamshela lesinyithi bumxinwa kakhulu, abunakumelana ne-40kA yangoku
Uhlobo lukaDehn:
Enkosi kuyilo olusengqiqweni, inokumelana ne-Imax = 40kA yangoku.
(1.4) Indlu yeplastiki
izinto ezisemgangathweni yi-PA66 okanye inayiloni yothintelo lomlilo.
(1.5) Amalungu esinyithi, izinto ezingundoqo zentsimbi kufuneka zisebenzisane, hayi intsimbi.
Isitayile se-OBO sisebenzisa iindawo zensimbi zentsimbi:
Isitayile sikaDehn sisebenzisa iindawo zentsimbi ebambisanayo:
(1.6) Izinto zokukhusela indalo
Omnye umzi-mveliso usebenzisa i-epoxy resin ukutywina. I-epoxy resin iyanuka kwaye ayilunganga kukhuseleko lwendalo kunye nempilo.
Sisebenzisa i-varistor eyambathisiweyo, ayifuni i-epoxy resin, kungcono ukukhuselwa kwendalo.
2. Ukuzenzekelayo kwemveliso
Amalungu esinyithi aqhagamshelene ne-MOV (varistor) kufuneka iwelding ngokuthembekileyo. ukuba i-welding yesandla, kwenzeka lula ukuba i-solder engonelanga. Ke iwelding ezenzekelayo inokugcina ukuhambelana komgangatho wemveliso. https://www.youtube.com/watch?v=RHwNJv8hobE

7. Isiqinisekiso Semveliso
Uphawu oludumileyo njengoDehn, i-OBO, babonelela ngeminyaka emi-5 iwaranti. ukuba umenzi uyaqinisekisa ukuba unikezela ngemveliso esemgangathweni, kuya kufuneka ibonelele ngesiqinisekiso seminyaka emi-3-5.
8. Iphakheji
Nokuba yeyiphi imveliso yefektri okanye i-OEM, umenzi kufuneka abonelele ngesitampu esifanelekileyo (iserigraphy), iphakheji (ibhokisi kunye nebhokisi), iphepha okanye incwadana ye-elektroniki (imiyalelo yofakelo)
Ungayikhetha njani into yokukhusela isixhobo somenzi we-SPD, La manqaku ma-8 abalulekileyo okuthenga isixhobo esikhuselekileyo sokukhusela esivela e-China, ndiyathemba ukuba siluncedo
Siyinkampani yosapho evela kwaye besibonelela ngezixhobo zokukhusela (SPD) kwihlabathi liphela ngaphezulu kweminyaka eli-10. Sinezethu uphando kunye nophuhliso, imveliso, inkxaso yezobugcisa kunye nokuvavanya elebhu ngokunjalo.
I-LSP ziveliswa kungekuphela nje ezakhiweni zokuhlala nezingezizo ezokuhlala, kodwa nakwizicelo zeshishini ezinje ngemibhobho yeoyile, imibhobho yegesi, iifotovoltaics, izitishi zamandla kunye noololiwe. Iimveliso zethu zikhusela ekuqhubekeni kwetekhnoloji, oomatshini, izixhobo kunye nezixhobo kwihlabathi liphela.
Sikwaphuhlisa kwaye senze izixhobo zokubeka iliso (i-IMD) yothungelwano lwamandla e-IT. Sinikezela ngesisombululo esibanzi, esimbaxa ku-A ukuya ku-Z ekubekeni iliso kwimeko yokugquma kwizibhedlele, amashishini kunye nezicelo ezizodwa.
Asizenzi ngathi sinokwenza yonke into, ukuba unayo nayiphi na imibuzo kunye nengcebiso malunga nezinto ze-SPDs, iqela lethu labachwephesha abanezakhono bayakuvuyela ukuphendula imibuzo yakho kwaye bakufumanele imveliso efanelekileyo.
