I-srew terminal uhlobo lwe-high voltage ceramic capacitor ebizwa nangokuthi "Isiphathimandla seDoorknob"ngesiNgisi noma  I-High Voltage Screw Terminal Ceramic Capacitor. Inkampani yaseJapan edumile iTDK (Tokyo Denkikagaku Kogyo) ibhekisela kuyo ngokuthi "I-Ultra High Voltage Ceramic capacitor." Njengoba isikhondlakhondla se-elekthronikhi sase-Japan u-Murata samemezela ukuyekwa kwama-capacitor ayisikulufu se-screw terminal capacitor ekwindla ka-2018, isabelo semakethe esiphezulu e-China siphethwe uhlobo lwase-Japan i-TDK. I-TDK inesipiliyoni seminyaka engaphezu kwengu-40 ekwenzeni nasekukhangiseni kwama-capacitor e-ceramic anamandla kagesi aphezulu, asetshenziswa kakhulu kuma-transformer kagesi asekhaya aseShayina, ama-circuit breaker, imishini yezokwelapha esezingeni eliphezulu ye-CT, ukuhlolwa kwezimboni kwe-NDT okungabhubhisi, i-laser enamandla amakhulu. izikhali, ama-high-voltage electrostatic precipitators, njll. Ukugxila kwezokuthengisa kwe-TDK ikakhulukazi kuse-Japan, South Korea, Russia, kanye nesifunda sase-Asia-Pacific, ngobukhona obuncane uma kuqhathaniswa ezimakethe zase-Europe nezaseMelika.

 

Kusukela esikhathini sikaMongameli wangaphambili wase-US uTrump, kuye kwabekwa imingcele ezinkampanini zaseShayina mayelana nezinto zobuchwepheshe obuphezulu njengama-chips asezingeni eliphezulu nezingxenye ze-elekthronikhi. Izinkampani eziningi ezisohlwini, amabhizinisi kahulumeni, kanye nabakhiqizi bemishini emikhulu e-China sebeqalile ukubheka ezinye izindlela zasekhaya zezingxenye ezibalulekile. Okunye futhi kufakwe esikhundleni se-TDK's ultra-high voltage ceramic capacitor nakho kufakwe ku-ajenda.

 

Eqinisweni, omunye umkhiqizi we-ceramic capacitor we-ceramic osebenza kahle kakhulu we-high-voltage efana ne-HVC Capacitor baphumelele ukufaka esikhundleni se-ceramic capacitor yesikulufu esiphezulu se-ceramic capacitor kusuka kumkhiqizo owaziwa kakhulu wase-Japan i-MURATA kanye nohlobo lwaseMelika i-Vishay. Ama-HVC capacitor athole ukuqashelwa kokuhlolwa kwesikhathi eside ezinkampanini eziningi ezisohlwini lwaseYurophu naseMelika kanye nezinkampani ze-Fortune 500. Ngenxa yokulinganiselwa kwezinto ezibonakalayo nezithako, imikhiqizo ye-TDK ayinikezi izinga elifanayo lesipiliyoni kumakhasimende ase-Europe naseMelika njenge-MURATA yase-Japan kanye ne-Vishay yase-United States. Muva nje, kube nempendulo evela ezikhungweni zocwaningo zase-Europe naseShayina kanye namakhasimende wokugcina abonisa ukuthi imikhiqizo ye-TDK ingaphansi kwekhwalithi kanye namapharamitha athile uma kuqhathaniswa nama-capacitor e-HVC. Ngenxa yalokho, amakhasimende akhethe ukusebenzisa ama-HVC capacitor esikhundleni semikhiqizo ye-TDK yase-Japan. 

1) I-Voltage Esebenzayo Nebanga Lamandla: I-TDK i-ultra-high voltage ceramic capacitors: 20KV-50KV (Z5T, Y5P, Y5S materials); Uhlobo lwe-HVC doorknob uhlobo oluphezulu lwe-ceramic capacitor: 10KV kuya ku-150KV (izinto eziyinhloko yi-N4700, Y5U, Y5T, njll.). Imodeli yamandla kagesi aphezulu kakhulu ehlinzekwa yi-TDK okwamanje yi-FHV-12AN 50KV 2100PF, Y5S impahla. I-HVC inikeza imikhiqizo ejwayelekile kumakhasimende afana ne-50KV 8000PF N4700, 60KV 2000PF N4700, 150KV 1000PF N4700, nokuningi. Uma amakhasimende edinga i-voltage esebenzayo engaphezu kuka-50KV, ama-capacitor e-HVC anganikela ngezinhlobonhlobo ezicebile zama-voltage aphezulu kanye namandla amakhulu kakhulu.



2) Lihle kangakanani izinga lobuchwepheshe le-TDK's Z5T, Y5P, Y5S dielectric material capacitor?

Onjiniyela be-HVC empeleni balinganise i-TDK's 30KV 2700PF kanye ne-50KV 2100PF screw capacitor futhi bathola ukuthi nakuba i-TDK isebenzisa izitsha zobumba zeClass 2 Y5S, Z5T, nezinto eziqukethe umthofu (okuthiwa zingaphansi kohlelo lokukhululwa lwe-ROHS kuwebhusayithi yabo), i-DF (dissipation) amanani afinyelela ezingeni le-Class 1 ceramic N4700. Lokhu kudlula imikhiqizo yozakwabo baseShayina kulesi sici.
 

 

3) Isakhiwo sangaphakathi sama-capacitor: I-TDK's ultra-high voltage ceramic capacitor isebenzisa isakhiwo se-ceramic chip esivamile, futhi isikhunta se-epoxy resin encapsulation sinosayizi ojwayelekile ongu-60mm kuphela, njengoba kushiwo ngenhla, okhawulela idizayini kubukhulu obungu-50KV 2100PF Y5S capacitor. I-HVC isebenzisa isakhiwo sangaphakathi esinochungechunge lwe-dual-chip noma uxhumano olufanayo, oluvumela ukukhiqizwa kokucaciswa kwe-capacitor okudlula kude lokho kwabakhiqizi abaziwayo. Ama-Capacitor anama-voltage aphezulu afana no-80KV, 100KV, kanye no-150KV asuselwa ekuxhumekeni kochungechunge lwe-chip ezimbili, kuyilapho amanani omthamo we-Class 1 ceramic 5000PF kanye no-8000PF atholakala ngoxhumo oluhambisanayo lwe-dual-chip.


4)I-Disc coating neminye imininingwane: I-TDK Ceramic chip ibekwe ngokwesiko imboza amandla "ngesilver plating." Ama-ion esiliva angama-conductor amahle kakhulu kodwa futhi ajwayele ukufuduka. Ngokuphambene, ama-screw capacitor e-HVC amboza ngaphakathi i-ceramic chip ngama-electrode ethusi, anikeza ukumelana okungcono nogesi ophezulu namandla amanje aphezulu uma kuqhathaniswa nokucwecwa kwesiliva okuvamile. (The isithombe ngenhla ikhombisa ama-capacitor e-TDK angenawo ungqimba lwe-epoxy resin, esusiwe ukuze embule ama-ceramic chips ane-silver plating namatheminali ensimbi, kanye isithombe ngezansi bonisa ubuchwepheshe obuyingqayizivele bokucwenga ithusi ebusweni bama-HVC capacitor.)






Sengiphetha, i-TDK ne-HVC's screw terminal uhlobo lwe-ceramic capacitor ngayinye inezinzuzo zayo zobuchwepheshe, okubenza babe izimbangi ezifaniswe ngokulinganayo. Kwezinye izici, i-HVC idlula ngisho inkampani yaseJapan i-TDK. Kodwa-ke, uma kucatshangelwa izici ezifana nesikhathi sokuletha kanye nentengo abathengi abahlale beyicabangela, ukukhanga kwama-capacitor e-ceramic kagesi aphezulu kagesi we-TDK kuyawa ngokwemvelo uma kuqhathaniswa ne-HVC.

Ibhrendi yokuqala emhlabeni yama-capacitor e-ceramic ohlobo lwe-screw-voltage ephezulu yi-Japanese Murata. Ngo-2018, ngemuva kokuthi u-Murata ememezele ukuyeka ukukhiqiza, inkampani yaseMelika i-VISHAY kanye nenkampani yaseJapane i-TDK ngokulandelanayo bafuna ukugcwalisa isikhala semakethe esashiywa ngu-Murata ngokukhipha amaphephandaba kanye nohlu lwemininingwane "yereferensi" kumawebhusayithi asemthethweni e-TDK.



Uma uqhathanisa i-TDK yaseJapan kanye ne-American Vishay, i-HVC Capacitor iseyinketho engcono kune-Murata.

1) Kungaqashelwa ukuthi ukufaka esikhundleni kwe-TDK u-Murata kuwukushintsha nje okungalungile. Isibonelo, i-DHS4E4C532KT2B 15KV 5300PF N4700 ka-Murata ifaniswa ne-TDK nokushintshwa okuhambisanayo kwe-15KV 7000PF, Y5S. Siyazi ukuthi nakuba impahla ye-TDK ye-Y5S ibonisa ukusebenza okulinganiselwe kokulahlekelwa okuphansi, izilinganiso zangempela zibonisa amanani afana neleveli ye-N4700. Kodwa-ke, izitsha zobumba zeClass 2 ezifana ne-Y5S azikwazi ukusebenza kanye ne-Class 1 ceramics ezindaweni ezinemvamisa ephezulu. Ukwengeza, umthamo we-7000PF ovela ku-TDK ungase ube mkhulu kakhulu kumakhasimende ajwayele ukusebenzisa i-Murata capacitor, futhi ubukhulu bengxenye bungase bungahambisani nemikhiqizo yasekuqaleni ye-Murata. Uma kucatshangelwa ukuthi i-TDK iphinde ibe ngumkhiqizi omkhulu wamazwe ngamazwe, ngaphandle uma amakhasimende engabathengi abanamandla ngokwedlulele, i-TDK ingase ingazimisele ukudizayina kabusha isikhunta futhi isebenzise izinga elifanayo lempahla yobumba ukuze kufakwe i-Murata esikhundleni.



Uma i-HVC ibizohlinzeka ngokushintshwa kwale modeli ye-Murata, okokuqala uhlu lomkhiqizo olujwayelekile lwe-HVC lwe-doorknob capacitor luphelele emakethe yemikhiqizo yesikulufu esinamandla kagesi aphezulu, oluhlanganisa wonke amamodeli ekhathalogi aphuma esigabeni esiphezulu kanye neseqophelweni lesibili kokubili ngaphakathi nangaphandle. emazweni ngamazwe, njenge-Murata, TDK, Vishay, HVCA, njll. Ngokuyinhloko, noma iyiphi imodeli ye-Murata ekhishwe esidlangalaleni ku-inthanethi inesixazululo esenziwe ngomumo esivela ku-HVC. Ngisho nama-capacitor e-Murata anobukhulu obungokwezifiso namatheminali ensimbi kumakhasimende athile amakhulu angase angabonakali ku-inthanethi (isibonelo, i-40KV 3000PF N4700 capacitor evela ebhizinisini elikhipha imisebe engaphansi kwe-Sumitomo Electric yase-Japan), i-HVC izohlinzeka ngesixazululo sangokwezifiso esingu-1:1 kakhulu. izindleko zesikhunta eziphansi. Ngaphezu kwalokho, amandla, ukubekezelelana, izinto ezibonakalayo, njll., empeleni kufana nokucaciswa kwe-Murata kwasekuqaleni, futhi kwezinye izimo, i-HVC isebenzisa izinto zobumba ze-Class 1 "N4700" ukuze zithathe indawo ye-ceramics ye-Murata's Class 2 "Z5U", efana kakhulu Indaba yakudala yaseShayina ethi "Umjaho Wehhashi Elisheshayo."

2) Ngaphezu kwalokho, nakuba i-TDK ingumkhiqizi wezingxenye ze-elekthronikhi wase-Japan owaziwa umhlaba wonke, amazinga okuxhumana obuchwepheshe kanye nesevisi yamagatsha nama-ejenti e-TDK angaphandle kwase-Japan awaqinile njengalawo ama-ejenti e-HVC. Kube khona izimo lapho ikhasimende lenkampani kagesi yaseJalimane libike ukuthi lapho lihlola ngawo womabili ama-capacitor e-TDK kanye ne-HVC, umenzeli we-TDK akazange anikeze ukwesekwa okwanele kwezobuchwepheshe. Ngokuphambene, i-ejenti yaseJalimane ye-HVC, i-AMEC, yavakashela amakhasimende abalulekile ngokuqhubekayo, yaqinisekisa ukwaneliseka kwamakhasimende ngokuxhumana okuphumelelayo kobuchwepheshe, futhi yabonisa ukuguquguquka ekusebenzeni, okushiya umbono omuhle kumakhasimende. Ezimbonini ezifana nemishini ebalulekile efana neziguquli zamandla, ukwesekwa kobuchwepheshe kwaziswa kakhulu ngamakhasimende okugcina.

3) Ngemva kweminyaka yomzamo, i-HVC Capacitor iye yazuza ukuqashelwa futhi yazuza ukuthunyelwa kwenqwaba kumakhasimende e-screw capacitor anamandla kagesi afana no-Nikon, u-Konica Minolta, i-GE Healthcare, u-Johnson & Johnson, u-Baker Hughes, nabanye. Ukusebenza kwebhizinisi namakhasimende ase-Japan kanye nezinkampani ze-Fortune 500 kubonisa ukuthi i-HVC Capacitor ihlangabezana nezidingo eziqinile zobuchwepheshe zamakhasimende wokugcina afuna kakhulu embonini.




Kafushane, i-HVC Capacitor iwukungena esikhundleni esifaneleka kakhulu sama-screw capacitor ane-voltage ephezulu yomkhiqizo waseJapan i-Murata uma kuqhathaniswa ne-TDK. Ngokwezinga elithile, imikhiqizo ye-HVC inganikeza amakhasimende akhona e-TDK ultra-high voltage capacitor umuzwa ohlukile wobuchwepheshe.

Ngezansi amamodeli wokuqhathanisa webanga eligcwele lama-screw capacitor aphezulu kusuka ku-TDK ne-HVC:
