Ƙarƙashin ƙarfin ƙarfin yumbu capacitors gabaɗaya ana iya rarraba shi zuwa rukuni uku. Lokacin amfani da waɗannan capacitors, karaya na iya faruwa, wanda sau da yawa ya dagula masana da yawa. An gwada waɗannan capacitors don ƙarfin lantarki, ɓataccen abu, fitarwa na yanki, da juriya na rufi yayin siyan, kuma duk sun wuce gwaje-gwajen. Duk da haka, bayan watanni shida ko shekara na amfani, an sami wasu manyan ƙarfin yumbun capacitors sun fashe. Shin wadannan karaya ne suka haifar da capacitors kansu ko abubuwan muhalli na waje?
Gabaɗaya, ana iya danganta fashewar babban ƙarfin yumbu capacitors zuwa masu zuwa yiwuwa uku:
Yiwuwar farko ita ce thermal bazuwar. Lokacin da capacitors ke fuskantar gaɗaɗɗen mitoci na gaggawa ko dadewa da yanayin aiki na yanzu, masu ƙarfin yumbu na iya haifar da zafi. Kodayake yawan samar da zafi yana jinkirin, yanayin zafi yana tashi da sauri, yana haifar da bazuwar thermal a yanayin zafi mai yawa.
Yiwuwar ta biyu ita ce lalatar sinadarai. Akwai gibi tsakanin ƙwayoyin ciki na yumbu capacitors, kuma lahani kamar fashe da ɓoyayyiyi na iya faruwa yayin aikin kera capacitor (masu haɗari a cikin samar da ƙananan kayayyaki). A cikin dogon lokaci, wasu halayen sunadarai na iya haifar da iskar gas kamar ozone da carbon dioxide. Lokacin da waɗannan iskar gas suka taru, za su iya yin tasiri ga murfin rufewa na waje kuma su haifar da raguwa, haifar da tsagewa.
Yiwuwar ta uku ita ce rushewar ion. Babban ƙarfin wutar lantarki yumbu capacitors sun dogara da ions suna motsawa ƙarƙashin rinjayar filin lantarki. Lokacin da ions ke ƙarƙashin filin lantarki mai tsawo, motsinsu yana ƙaruwa. A cikin yanayin halin yanzu da ya wuce kima, za a iya lalacewa Layer Layer, wanda zai haifar da lalacewa.
Yawancin lokaci, waɗannan gazawar suna faruwa bayan kusan watanni shida ko ma shekara guda. Koyaya, samfuran masana'antun masu ƙarancin inganci na iya gazawa bayan watanni uku kacal. Ma'ana, tsawon rayuwar waɗannan manyan ƙarfin yumbun capacitors watanni uku ne kawai zuwa shekara ɗaya! Don haka, wannan nau'in capacitor gabaɗaya baya dace da kayan aiki masu mahimmanci kamar grid mai wayo da janareta masu ƙarfi. Abokan ciniki na grid mai wayo yawanci suna buƙatar capacitors don ɗaukar shekaru 20.
Don tsawaita tsawon rayuwar capacitors, ana iya la'akari da shawarwari masu zuwa:
1)Sauya kayan dielectric na capacitors. Misali, da'irori na asali ta amfani da X5R, Y5T, Y5P, da sauran yumbu na Class II ana iya maye gurbinsu da yumbu na Class I kamar N4700. Duk da haka, N4700 yana da ƙaramar dielectric akai-akai, don haka capacitors da aka yi da N4700 za su sami girman girma don irin ƙarfin lantarki da ƙarfin aiki. Kayan yumbu na Class I gabaɗaya suna da ƙimar juriya fiye da sau goma sama da tukwane na Class II, suna ba da ƙarfin rufewa sosai.
2)Zaɓi masana'antun capacitor tare da ingantattun hanyoyin walda na ciki. Wannan ya shafi flatness da flawlessness na yumbu faranti, da kauri na azurfa plating, da cikar yumbu farantin gefuna, ingancin soldering ga take kaiwa ko karfe tashoshi, da kuma matakin epoxy shafi encapsulation. Wadannan cikakkun bayanai suna da alaƙa da tsarin ciki da ingancin bayyanar capacitors. Capacitors tare da mafi kyawun bayyanar yawanci suna da mafi kyawun masana'anta na ciki.
Yi amfani da capacitors guda biyu a layi daya maimakon capacitor guda ɗaya. Wannan yana ba da damar rarraba wutar lantarki ta asali ta hanyar capacitor guda ɗaya tsakanin capacitors guda biyu, yana haɓaka ƙarfin ƙarfin ƙarfin gabaɗaya. Koyaya, wannan hanyar tana haɓaka farashi kuma tana buƙatar ƙarin sarari don shigar da capacitors biyu.
3) Domin musamman high irin ƙarfin lantarki capacitors, kamar 50kV, 60kV, ko ma 100kV, Za'a iya maye gurbin tsarin haɗe-haɗe na al'ada guda ɗaya yumbura tare da jerin farantin yumbu mai Layer biyu ko tsarin layi ɗaya. Wannan yana amfani da capacitors na yumbu mai Layer biyu don haɓaka ƙarfin jurewar wutar lantarki. Wannan yana samar da isasshe babban tabar wutar lantarki, kuma mafi girman gefen wutar lantarki, mafi tsayin tsawon rayuwar da ake iya faɗi na capacitors. A halin yanzu, kawai kamfanin HVC zai iya cimma tsarin ciki na babban ƙarfin yumbu capacitors ta amfani da faranti biyu na yumbu. Koyaya, wannan hanyar tana da tsada kuma tana da wahalar aiwatar da samarwa. Don takamaiman cikakkun bayanai, da fatan za a tuntuɓi ƙungiyar tallace-tallace da injiniyoyi na kamfanin HVC.
