Kwe-dielectric Heating - kuyini? izakhiwo Kwe-dielectric Heating

Kwe-dielectric Heating - material noma into kakhulu aluphumeleli kagesi. conductivity okunjalo kutholakala ngenxa yenani elincane electron futhi ion. Lezi zinhlayiya akhiwa kule impahla non-Umqhubi kuphela lapho izakhiwo ephezulu lokushisa. Iqiniso lokuthi onjalo yisivikelo futhi uzobe okuxoxwe ngazo kulesi sihloko.

incazelo

Ngamunye umqhubi ngogesi noma Radiotechnical, Semiconductor noma yisivikelo icala yedlula zamanje kagesi, kodwa sici Kwe-dielectric Heating ukuthi ngisho ngesikhathi voltage okusezingeni eliphezulu kuka-550 V ngeke angena esincane samanje. Amandla kagesi kuleli yisivikelo - kuba ukunyakaza izinhlayiya icala indlela ethile (kungenzeka emihle noma emibi).

izinhlobo imisinga

At inhliziyo conductivity Kwe-dielectric Heating yilezi:

• Absorption wamanje - zamanje yiwo ogelezela e-Kwe-dielectric Heating ngesikhathi samanje njalo kuze kube yilesi sikhathi, aze afinyelele isimo yakhoibrium, ukushintsha isiqondiso lapho supply voltage kuso nalapho nokunqamula. Lapho kushintshana umfutho samanje Kwe-dielectric Heating uzoba khona kulo ngazo zonke izikhathi, namanje in inkambu kagesi.
• Electronic conductivity - ezihambayo electron ngaphansi kwethonya emkhakheni.
• conductivity ionic - limele ukunyakaza ion. It elise electrolyte izixazululo - nosawoti, acid, insipho eningi, kanye dielectrics eziningi.
• Molionnaya conductivity - ukuhamba izinhlayiya icala ngokuthi molionami. Akhiwe izinhlelo colloidal, emulsions kanye ukumiswa. Molionov mkhuba ezinyakazayo emkhakheni kagesi libizwa electrophoresis.

izinto nangokuvikela ihlukaniswa by isimo wokuhlanganisa nemvelo zamakhemikhali. Eyokuqala ihlukaniswe okuqinile, uketshezi, gaseous futhi qinisa. Ngokusho uhlobo chemical zihlukaniswe engokwemvelo, inorganics futhi izinto organometallic.

Conductivity dielectrics uthi we wokuhlanganisa:

• Conductivity amagesi. Esikhathini izinto gaseous ngokwanele encane conduction zamanje. Lesi simo singenzeka kunoma khona khulula izinhlayiya icala, okuyinto eyenzeka ngenxa ithonya ionic elekthronikhi izici bangaphandle zangaphakathi:-X-ray emisebeni nezinhlobo enemisebe, ukushayisana lwama-molecule izinhlayiya icala, izici ezishisayo.
• conductivity kagesi we uketshezi Kwe-dielectric Heating. Ukuncika: isakhiwo engqamuzaneni, izinga lokushisa, ukungcola, khona amacala enkulu electron futhi ion. Conductivity ka dielectrics ketshezi kuncike khona umswakama futhi akhiphe amanyela. Conduction kagesi wadala izinto polar ngaphezulu nge uketshezi kuma-athomu dissociated. Ngokuqhathanisa nokusaketshezi elimboze izindawo ezibandayo kanye non-polar, inzuzo ahlukile conductivity uqale. Uma ketshezi kucacile ukungcola, izosiza ukuncipha kwempahla yayo eqhubekayo. Nge ekukhuleni conductivity efana ketshezi kanye lokushisa yalo wehlise viscosity yayo kwenzeka, okuyinto kuholela ion ukuhamba.
• dielectrics okuqinile. electroconductivity yabo kubangelwa njengoba ukuhamba icala izinhlayiya Kwe-dielectric Heating futhi akhiphe amanyela. Ngo Amasimu eziqinile kagesi Kutholwe conductivity zamanje.

Izakhiwo dielectrics

Lapho resistivity we indaba elilingana esingaphansi 10-5 Ohm * m akunakubangelwa babashayeli. Uma kuka 108 Ohm * m - kuya dielectrics. Kukhona amacala lapho resistivity izikhathi eziningana njengengcebo enkulu kunemicebo ukumelana umqhubi. Esikhathini uhla 10-5-108 Ohm * m kuyinto Semiconductor. Metallic impahla - umbhidisi omuhle kakhulu kagesi.

Of lonke ishadi lesikhathi salezi izakhi, 25 kuphela-non-izinsimbi, ne-12 kubo cishe uyobe nge Semiconductor izakhiwo. Kodwa-ke, ngaphandle ithebula izinto, kusekhona Alloys eziningi, izingoma noma zamakhemikhali nge umqhubi impahla, Semiconductor noma Kwe-dielectric Heating. Ngakho, kunzima ukuba bafeze izinto ezithile ezahlukene eboshiwe ka resistances yabo. Ngokwesibonelo, ngo-enciphile lokushisa isici Semiconductor ngeke behave fana Kwe-dielectric Heating.

isicelo

Ukusetshenziswa non-Umqhubi izinto kumba eqolo, ke ingenye amakilasi edume wasebenzisa izingxenye kagesi. Sekuvele Kucacile ukuthi zingasetshenziswa yinoma property ifomu yekwentiwa.

Esikhathini yokwenziwa ifomu Kwe-dielectric Heating izakhiwo ezisetshenziselwa izicelo e kagesi nangokuvikela impahla.

Ngendlela asebenzayo, bajwayele endaweni ferroelectric futhi izinto ubuchwepheshe ngoba laser emitters.

dielectrics main

Ukuze njalo ezenzeka zinhlobo zihlanganisa:

• Glass.
• Rubber.
• Oil.
• Asphalt.
• Zobumba.
• Quartz.
• Air.
• Diamond.
• Amanzi ahlanzekile.
• Plastic.

Kuyini uketshezi Kwe-dielectric Heating?

I nokwehlukana lolu hlobo kwenzeka emkhakheni kagesi. Liquid impahla non-conductive asetshenziswe art ukusakaza noma bakhulelisa izinto. Kukhona 3 amakilasi of dielectrics uketshezi:

Petroleum amafutha - ziphansi-viscosity futhi ikakhulu-non-polar. Avame esetshenziswa imishini ephezulu voltage: uwoyela transformer, amanzi okusezingeni eliphezulu. uwoyela transformer - a Kwe-dielectric Heating non-polar. uwoyela Ikhebula iye yasetshenziswa kule impregnation nangokuvikela iphepha yamandla aphindeke kabili izintambo kubo kuze kufinyelele 40 kV, kanye enamathela metal ezisekelwe nge samanje ezingaphezu kuka-120 kV. uwoyela transformer njengoba kuqhathaniswa capacitor has a isakhiwo net. Lolu hlobo lwe-yisivikelo kabanzi lisetshenziswe ukukhiqizwa, naphezu kwezindleko nomsebenzi omkhulu uma kuqhathaniswa ne izinto analog izinto.

Kuyini zokwenziwa yisivikelo? Njengamanje cishe yonke indawo waphika ngenxa ubuthi okusezingeni eliphezulu Kuye kwenziwa ngesisekelo carbon kampompi ukuxova umuthi wokugoma. A ketshezi Kwe-dielectric Heating, esekelwe Silicon organic, iphephile futhi imvelo. Lolu hlobo akakubangeli ukugqwala zensimbi has izakhiwo hygroscopicity ongaphakeme. Kube thinned yisivikelo ehlanganisa kwakwakhe organofluorine okuyinto ethandwa kakhulu ngenxa incombustibility zabo, izakhiwo ezishisayo kanye oxidative ukuzinza.

Uyibuka okokugcina, ke amafutha zemifino. Ziyakwazi wavuma dielectrics polar, lokhu kuhlanganisa linseed, ocolisekileyo, tung, Sesame. uwoyela Castor kushisa kakhulu futhi isetshenziswa ephepheni capacitors. Amafutha esisele - oluyingozi. Ukuhwamuka therein kubangelwa yini ukuhwamuka zemvelo, ukusabela zamakhemikhali ezibizwa ngokuthi polymerization. Ngezenzo elisetshenziswa enamels nopende.

isiphetho

Lesi sihloko sabuyekezwa ngokuningiliziwe, lokho yisivikelo. izinhlobo ezahlukene kanye nezici zabo ziye okukhulunywa. Yiqiniso, ukuqonda ubuhlakani izici, kubalulekile ukuhlola okwengeziwe egatsheni physics ngazo.
