Izinhlobo capacitors: ubukghoni nokubhalelwa

A capacitor kuyinto zobuchwepheshe okuvumela ukugcina bese ukuletha i osenyameni kagesi. Isici esiyinhloko we isici umthamo wayo, sokunquma ukwencika icala voltage.

Ukwahlukaniswa condensers

amadivaysi abahlukahlukene ukukhulula ubuchwepheshe ukuvumela ukukhiqiza izinhlobo ezehlukene amadivaysi. Ngu emoyeni condensers nezihloko lapho Kwe-dielectric Heating kuyinto emoyeni. Izinzuzo lolu hlobo amadivayisi kalula enza. Ziklanyelwe for mechanical ukulawula umthamo futhi enzelwe okuqhubekayo umthelela lokukhanda. I yokuntula yalolu hlobo device zihlanganisa kokuntengantenga kwezomnotho, ukuthembeka abampofu, ukuncika umswakama lokushisa medium, usayizi esikhulu, iphansana amandla Kwe-dielectric Heating okuyinto engavimba emoyeni ukuwohloka phakathi sinkers kanye capacitance ongaphakeme.

Kukhona izinhlobo yephepha capacitors, okuyinto ethatha kungamafutha transformer Kwe-dielectric Heating elifakwe ephepheni. Lezi amadivayisi abe namandla Kwe-dielectric Heating nokwethembeka. Lapho zinamandla okusezingeni eliphezulu , banalo capacitance high and low ukuvuza zamanje.

capacitors Abaningi akhiqizwa on iphepha isisekelo izitshalo amandla. Ukuze wenze lokhu, phinda ndawonye amapuleti amabili, phakathi lapho ephepheni. Idivayisi ke iphuma ibe umqulu futhi ibekwe endaweni embizeni, okuyinto ugcwele ngamafutha transformer bese uphawu. I yokuntula zedivayisi zihlanganisa eziningi isisindo, okusezingeni eliphezulu self-inductance kanye nemithi.

capacitors electrolytic izinhlobo Kwe-dielectric Heating, okwethulwa ngesimo isendlalelo oxide kwakhiwa phezu kwensimbi asebenzayo (ngokuvamile aluminium). , Lapho kwakhiwa Idivayisi ezivezwa ukubeka i electrolyte elenziwe ngesikhumba tape metal asebenzayo ebusweni ifilimu is kusuka oxide okuhlala, okuvumela ukuba bahlukanise metal.

Isici esiyinhloko we capacitors electrolytic kuba phambi zezintaka polarity, omunye ukubaluleka ukuthi ubambe voltage ukalwe, futhi uma lushintsha ngokushesha wabhubhisa. Lokhu kungenxa yezinqubo zamakhemikhali ezenzeka phakathi electrolyte kanye ipuleti metal. Oxide ifilimu kancane kancane imifantu futhi amakhefu.

Nokho, kuhambisana lesifanele polarity microcracks ngokushesha some oxide entsha. Izinzuzo zalezi amadivaysi zibandakanya umthamo omkhulu, ukushiyeka - polarity, balahlekelwa impahla yabo, bafake okusheshayo, eliphezulu inductance yangaphakathi.

Izinhlobo capacitors futhi izicelo zabo

Kukhona futhi kumadivayisi lapho ukhonza njengomdala mica Kwe-dielectric Heating, zisetshenziswe ukufaka ezahlukene. Njengoba mica wedwa okwazi ukugcina amandla, lezo zinhlobo capacitors babe capacitance okusezingeni eliphezulu namandla Kwe-dielectric Heating. I yokuntula zihlanganisa kwemigomo kokuntengantenga kwezomnotho, nonlinearity, inani lentengo eliphezulu futhi ukwencika zamanje capacitance.

Ngaphezu kwalokho ukusetshenziswa senziwa ezinhlobo Ceramic ka capacitors, ifilimu, Teflon, polypropylene namanye amadivayisi.
