I-terminal ye-srew uhlobo lombane ophezulu we-ceramic capacitor ikwabizwa ngokuba "Umnyango weCapacitor" ngesiNgesi okanye  High Voltage Screw Terminal Ceramic Capacitor. Inkampani yaseJapan eyaziwayo iTDK (Tokyo Denkikagaku Kogyo) ibhekisela kuyo njenge "Ultra High Voltage Ceramic capacitor." Ekubeni i-electronics yaseJapan i-Murata ibhengeze ukupheliswa kwe-high voltage screw terminal capacitors ekwindla ngo-2018, isabelo semarike esiphezulu e-China sibanjwe yi-Japan brand TDK. I-TDK ineminyaka engama-40 yamava okuvelisa kunye nokuthengisa i-ultra-high voltage ceramic capacitors, ezisetyenziswa ngokubanzi kwii-transformers zamandla zasekhaya zaseTshayina, ii-circuit breakers, oomatshini be-CT zonyango abaphezulu, uvavanyo lwe-NDT lwemizi-mveliso olungonakalisi, i-laser enamandla kakhulu. izixhobo, i-high-voltage electrostatic precipitators, njl. njl. Intengiso ye-TDK igxile ikakhulu eJapan, eMzantsi Korea, eRashiya, nakummandla we-Asia-Pacific, kunye nobukho obuncinane kwiimarike zaseYurophu nezaseMelika.

 

Ukusukela ngexesha lalowo wayesakuba nguMongameli wase-US uTrump, kuye kwamiselwa izithintelo kwiinkampani zaseTshayina malunga nezinto ezikumgangatho ophezulu ezinje ngeetshiphusi eziphezulu kunye neenxalenye ze-elektroniki. Iinkampani ezininzi ezidwelisiweyo, amashishini karhulumente, kunye nabavelisi bezixhobo ezinkulu e-China sele beqalisile ukuqwalasela ezinye iindlela zasekhaya kumacandelo aphambili. Enye indlela kunye nokutshintshwa kweecapacitors zeceramic zamandla ombane aphezulu we-TDK nazo zibekwe kwi-ajenda.

 

Ngapha koko, omnye umenzi wecapacitor we-ceramic obalaseleyo waseTshayina onjenge-HVC Capacitor utshintshe ngempumelelo i-screw terminal ye-ceramic capacitors ye-ceramic capacitors evela kwi-brand eyaziwayo yaseJapan i-MURATA kunye ne-American brand Vishay. I-HVC capacitors ifumene ukuqondwa kovavanyo lwexesha elide kwiinkampani ezininzi ezidweliswe eYurophu naseMelika kunye neenkampani zeFortune 500. Ngenxa yokulinganiselwa kwezinto eziphathekayo kunye nezithako, iimveliso zeTDK aziboneleli ngenqanaba elifanayo lamava kubathengi baseYurophu naseMelika njengeMURATA yaseJapan kunye neVishay evela eUnited States. Kutshanje, kukho ingxelo evela kumaziko ophando aseYurophu naseTshayina kwaye abathengi bokugqibela babonisa ukuba iimveliso zeTDK ziphantsi kumgangatho kunye neeparitha ezithile xa kuthelekiswa ne-HVC capacitors. Ngenxa yoko, abathengi bakhethe ukusebenzisa i-HVC capacitors endaweni yeemveliso zaseJapan zeTDK. 

1) I-Voltage esebenzayo kunye noluhlu lweCapacitance: I-TDK i-ultra-high voltage ceramic capacitors: 20KV-50KV (Z5T, Y5P, Y5S izinto); Uhlobo lwe-HVC doorknob high-voltage ceramic capacitors: 10KV ukuya kwi-150KV (izinto eziphambili ziyi-N4700, Y5U, Y5T, njl.). Owona mzekelo uphezulu wokusebenza kwamandla ombane ngoku obonelelwa yi-TDK yi-FHV-12AN 50KV 2100PF, Y5S imathiriyeli. I-HVC inikezela ngeemveliso eziqhelekileyo kubathengi abafana ne-50KV 8000PF N4700, 60KV 2000PF N4700, 150KV 1000PF N4700, kunye nokunye. Xa abathengi befuna amandla ombane okusebenza aphezulu kuno-50KV, ii-HVC capacitors zinokubonelela ngeendlela ezahlukeneyo zombane ophezulu kunye namandla amakhulu kakhulu.



2) Ulunge kangakanani umgangatho wobugcisa weTDK's Z5T, Y5P, Y5S dielectric material capacitors?

Iinjineli ze-HVC ngokwenene zalinganisa i-TDK's 30KV 2700PF kunye ne-50KV 2100PF i-screw capacitors kwaye yafumanisa ukuba nangona i-TDK isebenzisa i-Ceramics ye-Class 2 i-Y5S, i-Z5T, kunye nezixhobo eziqulathe i-lead (ezibizwa ngokuba phantsi kwenkqubo yokukhululwa kwe-ROHS kwiwebhusayithi yabo), i-DF (i-dissipation) amaxabiso afikelela kwinqanaba leClass 1 ceramic N4700. Oku kodlula iimveliso zabalingane baseTshayina kulo mba.
 

 

3) Ubume bangaphakathi bee-capacitors: I-TDK ye-ultra-high voltage ceramic capacitors isebenzisa isakhiwo se-ceramic enye ye-ceramic, kunye ne-epoxy resin encapsulation mold inobungakanani obuqhelekileyo obuyi-60mm kuphela, njengoko kukhankanyiwe ngasentla, okunciphisa uyilo ukuya kubuninzi be-50KV 2100PF Y5S capacitor. I-HVC isebenzisa i-innovative structure yangaphakathi ene-dual-chip series okanye i-parallel connection, eyenza ukuba kuveliswe iinkcukacha ze-capacitor ezidlula kakhulu ezo zabakhiqizi abaziwayo. Ii-Capacitors ezinombane ophezulu ezifana ne-80KV, 100KV, kunye ne-150KV zithathwe kuqhagamshelwano lwe-chip ezimbini, ngelixa ixabiso le-capacitance ye-Class 1 ceramic 5000PF kunye ne-8000PF iphunyezwa ngokudityaniswa kwe-dual-chip parallel.


4)Idiskhi yokwaleka kunye nezinye iinkcukacha: Imiphezulu ye-ceramic ye-TDK ye-ceramic ngokwesiko igquma amandla ngokusebenzisa "isilivere yokucwenga." Iiyoni zesilivere ziziqhubi ezigqwesileyo kodwa zikwathanda ukufuduka. Ngokwahlukileyo koko, i-HVC screw capacitors yangaphakathi yambathisa i-ceramic chip kunye ne-electrode yobhedu, inika ukuxhathisa okungcono kumbane ophezulu kunye namandla aphezulu angoku xa kuthelekiswa nokufakwa kwesilivere eqhelekileyo. (Ii umfanekiso ongentla ibonisa i-TDK capacitors ngaphandle kwe-epoxy resin layer, isusiwe ukuze ibonise iitshiphusi ze-ceramic ezine-plating yesilivere kunye neetheminali zetsimbi, kunye umfanekiso ongezantsi bonisa itekhnoloji eyodwa yokucwenga yobhedu kumphezulu we-HVC capacitors.)






Ukuqukumbela, i-TDK kunye ne-HVC's screw uhlobo lwe-ceramic capacitors nganye ineenzuzo zayo zobuchwepheshe, ibenza bakhuphisane ngokulinganayo. Kwezinye iinkalo, i-HVC ide igqwese ngakumbi kwinkampani yaseJapan iTDK. Nangona kunjalo, ukuthathela ingqalelo izinto ezinje ngexesha lokuhanjiswa kunye namaxabiso abathengi abasoloko bewathathela ingqalelo, umtsalane we-TDK's Ultra-high voltage ceramic capacitors ye-ceramic capacitors ngokwendalo iyawa mfutshane xa kuthelekiswa ne-HVC.

Olona phawu lwehlabathi lwe-high-voltage screw-type ceramic capacitors yiMurata yaseJapan. Ngo-2018, emva kokuba u-Murata ebhengeze ukuyeka ukuvelisa, inkampani yaseMelika i-VISHAY kunye nenkampani yaseJapan i-TDK ngokulandelanayo yafuna ukugcwalisa i-vacuum yemarike eshiywe ngu-Murata ngokukhupha ushicilelo kunye noluhlu "lwe-cross-reference" ulwazi kwiiwebhusayithi ezisemthethweni zeTDK.



Xa uthelekisa i-TDK yaseJapan kunye ne-American Vishay, i-HVC Capacitor iseyeyona ndlela ingcono kune Murata.

I-1) Ingaqatshelwa ukuba indawo ye-TDK ye-Murata yinto nje yokuthatha indawo engafanelekanga. Umzekelo, i-DHS4E4C532KT2B ka-Murata 15KV 5300PF N4700 ihambelana ne-TDK kunye ne-substitute ehambelanayo ye-15KV 7000PF, Y5S. Siyazi ukuba nangona imathiriyeli ye-TDK ye-Y5S ibonisa ilahleko ephantsi yokusebenza okulinganiselweyo, imilinganiselo yokwenyani ibonisa amaxabiso afana nenqanaba le-N4700. Nangona kunjalo, ii-ceramics zeKlasi yesi-2 njenge-Y5S azikwazi ukwenza kunye neekeramics zeKlasi yoku-1 kwiindawo eziphezulu. Ukongezelela, umthamo we-7000PF ovela kwi-TDK unokuba mkhulu kakhulu kubathengi abajwayele ukusebenzisa i-Murata capacitors, kwaye imilinganiselo yecandelo ayinakuhambelana nemveliso ye-Murata yokuqala. Ukuqwalasela ukuba i-TDK ikwangumvelisi omkhulu wamazwe ngamazwe, ngaphandle kokuba abathengi bangabathengi abanamandla kakhulu, i-TDK isenokungakulungeli ukuyila ngokutsha iimolds kwaye isebenzise umgangatho ofanayo we-ceramic material yokutshintsha kwe-Murata.



Ukuba i-HVC ibinokubonelela ngokutshintshwa kwale modeli ye-Murata, okokuqala uluhlu lwemveliso eqhelekileyo ye-HVC ye-doorknob capacitor lolona lubanzi kwimarike yee-high-voltage screw terminal imveliso, equka zonke iimodeli zekhathalogu ukusuka kwi-top-tier kunye ne-second-tier brand zombini ngaphakathi nangaphandle. ngamazwe ngamazwe, njenge-Murata, TDK, Vishay, HVCA, njl. Okubalulekileyo, nayiphi na imodeli ye-Murata ekhutshwe esidlangalaleni kwi-intanethi inesisombululo esenziwe ngokufanelekileyo kwi-HVC. Nakwi-Murata capacitors enemilinganiselo elungiselelweyo kunye neetheminali zetsimbi kubathengi abathile abakhulu abanokuthi bangabonakali kwi-intanethi (umzekelo, i-40KV 3000PF N4700 capacitor esuka kwishishini elivuthayo phantsi kwe-Sumitomo Electric yaseJapan), i-HVC iya kunika isisombululo se-1: 1 kakhulu. ixabiso lokungunda eliphantsi. Ngaphaya koko, amandla, ukunyamezelana, izinto eziphathekayo, njl.njl., ziyafana ncakasana neMurata yantlandlolo, kwaye kwezinye iimeko, iHVC ide isebenzise iKlasi 1 "N4700" imathiriyeli yeekeramics ukuthatha indawo kaMurata's Class 2 "Z5U" imathiriyeli yeekeramics, efana kakhulu Ibali lakudala laseTshayina "loMdyarho weHashe eliSwift."

2) Ngaphaya koko, nangona i-TDK ingumvelisi wezinto zombane waseJapan owaziwayo kwihlabathi, unxibelelwano lobuchule kunye nenkonzo yamanqanaba e-TDK kunye neearhente ezingaphandle kweJapan azinamandla njengalawo abameli be-HVC. Kukho iimeko apho umthengi ovela kwinkampani yombane yaseJamani wabika ukuba xa kuhlolwa zombini i-TDK kunye ne-HVC capacitors, i-arhente ye-TDK ayizange ibonelele ngenkxaso yobugcisa eyaneleyo. Ngokwahlukileyo koko, i-arhente yaseJamani ye-HVC, i-AMEC, yatyelela ngokukhawuleza abathengi abaphambili, yaqinisekisa ukwaneliseka kwabathengi ngonxibelelwano olusebenzayo lobugcisa, kwaye yabonisa ukuguquguquka ekusebenzeni, ishiya ingcamango enhle kubathengi. Kumashishini afana nezixhobo eziphambili ezifana nabaguquli bamandla, inkxaso yobugcisa ixabiswa kakhulu ngabathengi bokugqibela.

I-3) Emva kweminyaka yomzamo, i-HVC Capacitor ifumene ukuqaphela kwaye iphumelele ukuthunyelwa kwezinto ezininzi ezivela kubathengi be-screw capacitor be-high-voltage efana ne-Nikon, i-Konica Minolta, i-GE Healthcare, i-Johnson & Johnson, i-Baker Hughes, kunye nabanye. Ukusebenza kweshishini kunye nabathengi baseJapan kunye neenkampani ze-Fortune 500 zibonisa ukuba i-HVC Capacitor ihlangabezana neemfuno ezingqongqo zobuchwepheshe zabona bathengi banzima kakhulu kwishishini.




Ngamafutshane, i-HVC Capacitor yeyona ndawo ifanelekileyo yokutshintsha i-screw capacitors ephezulu yevoltage evela kwi-brand yaseJapan i-Murata xa kuthelekiswa ne-TDK. Ukusa kumlinganiselo othile, iimveliso ze-HVC zinokunika abathengi abakhoyo be-TDK i-ultra-high voltage capacitors amava obuchwepheshe awohlukileyo.

Apha ngezantsi kukho uthelekiso loluhlu olupheleleyo lwe-high-voltage screw capacitors ukusuka kwi-TDK kunye ne-HVC:
