Kutshanje i-HVC Capacitor ifumene umbuzo ovela e-UK, Yinkampani edumileyo kwishishini "lolawulo lwe-static anti-static kunye nokhuseleko lwe-ESD", ukwenza kunye nokubonelela ngoluhlu olubanzi lweemveliso ze-electrostatic ezibonelela ngokhuseleko lwe-anti-static kunye ne-ESD kunye nokulinganisa, isizukulwana esingatshintshiyo, Ulawulo lwe-electrostatic kunye ne-elimination.Bafuna ii-capacitors ze-ceramic ze-ceramic eziphezulu zombane ukuze zithathe indawo ye-Murata. (DECB33J221KC4B 6.3KV 220PF Y5P ，DHRB34C681M2BB 16KV 680PF, Y5P)
Isizathu: I-Murata ngowona mvelisi odumileyo waseJapan ophakamileyo we-voltage capacitor, into yabo ekumgangatho ophezulu phakathi kweshishini. Ngo-2018, iMakethi ye-Murata yaqina i-voltage ephezulu ye-capacitor, ngoko ke umthengi okhoyo ujonge ngokukhawuleza ukusebenza okufanayo / into efanayo / inyawo lomthengisi we-ceramic capacitor.
Ubunzima beprojekthi:
Siyazi i-voltage ephezulu ye-ceramic capacitor kwisekethe yolawulo olusisigxina sisiphindaphindi samandla ombane omnye, ngumbane ophakamileyo wesekethe. HF frequency efana 20khz ukuya 40khz imeko yokusebenza. Nangona into yokuqala ye-Murata yi-Y5P iklasi ye-ceramic capacitor ye-ceramic, kodwa ikwazi ukumelana nomgangatho ophakathi kwi-frequency ephezulu njenge-30 ukuya kwi-40khz.
Kuya kubakho i-ripple current (i-peak voltage) ngexesha lesiphaluka kwi-off / off, lo mbane uya kuba ngama-2.8 ukuya kuma-3 amaxesha ombane wokufaka. umzekelo, ukuba igalelo lamandla ombane yi-6kv, amandla ombane aphezulu avuliwe ayakuba malunga ne-6x3=18kv.
Umthengi uzame enye i-Y5P hv ye-ceramic capacitor brand kodwa ayiphumelelanga.
Isisombululo se-HVC Capacitor:
Ngokusuka kumava okudlula, siyazi ukuba i-Murata yombane ophezulu we-ceramic capacitor esebenza kakuhle kwimeko yokusebenza rhoqo kunye ne-max ephezulu yokumelana nombane, umzekelo i-voltage elinganisiweyo: 15kv 1000pf Y5P, imelana kakhulu ne-voltage inokufikelela kumaxesha ama-3 ukuya kwi-45kv, ngoko i-Murata ibeka umda ophezulu we-voltage ukuya kwelinye okhuphisana naye, ngelixa abanye bexhathisa amandla ombane kuphela amaxesha ama-2, okanye nangaphantsi. Ke siyaqonda ukuba kutheni i-murata yeklasi ye-II capacitor sele ikwazi ukusinda kwisekethe yophinda-phindo lombane, kodwa elinye icandelo linokusilela ngokulula. Kwaye enye imfuno yokusebenzisa i-class I capacitor efana ne-NPO, SL, UJ, N4700. Emva koko unako ukusinda.
Ngoko isisombululo se-HVC sisebenzisa i-HVC ye-HVC-10KV-DL08-F10-221K (10KV 220pf N4700) ukuze ithathe indawo ye-Murata DECB33J221KC4B 6.3KV 220PF Y5P. Umthamo wamandla ombane aphezulu ukusuka kwi-6kv ukuya kwi-10kv, kunye nokumelana namandla ombane ngokunyuka kwama-30%. Kwakhona usebenzisa i-N4700 iklasi I-capacitor inokumelana ne-30khz ukuya kwi-100khz imeko ephakamileyo, ngoko i-capacitor ayiyi kuvelisa ukushisa okukhulu kwi-40khz.
Ukuba i-capacitor ayikwazi ukumelana ne-HF, iya kuba shushu kakhulu kwaye yonke imisebenzi efana ne-capacitance, ukumelana ne-insulation, i-dissipation factor iya kukhupha. Kwaye isekethe inokusilela.
Isiphumo:
Emva kokuvavanya umthengi isampuli ye-HVC Capacitor kwaye uqale umyalelo welingo kwaye ekugqibeleni uye kwi-odolo enkulu.
Kwaye 3 iminyaka kungekho ngxaki umgangatho kwenzeka.
I-HVC Capacitor yi-brand evelayo yombane ophezulu we-ceramic capacitors kunye ne-capacitor ye-doorknob, amandla okuvelisa ukusuka kwi-1kv ukuya kwi-70kv, kunye ne-patent ye-ceramic dielectric kunye nokugcina umgangatho ophezulu wokusebenza, osele utshintshile kunye nolunye uhlobo lwe-hv capacitor eyaziwayo njengoMurata, Vishay, TDK. AVX. Jonga apha ufumane ii-HVC's
Murata HV capacitor replacement
I-HVC Capacitor ikwakha ijelo losasazo lamazwe ngamazwe, kunye nomthengi ovela eYurophu, eU.SA, eKorea, eJapan bonke banokuthenga into yethu ekuhlaleni, kubandakanya intlawulo yasekhaya kunye nenkonzo yolungiselelo.
