Isilawuli lokushisa ezifundeni ukulawula

Automatic control izinhlelo yakhelwe ukulawula nemingcele ezifana wamanje, voltage, amandla, ingcindezi, njll Indawo ekhethekile lolu hlobo lwesistimu kunikezwa ukulawula izikimu. Kuye into, sebenzisa iphuzu elilodwa noma ezinye ukulawula isimiso. Uma sinesithakazelo kwesikwenzayo Ukushisa izakhi ke lokhu izicelo kakhulu asikho isidingo ukwakha wesifunda ngesivinini. Lokhu lula wesifunda ukuqaliswa idivayisi, futhi, okubaluleke kakhulu, ikuvumela ukuthi usebenzise "mnene" modi amandla amamojuli. Le ndlela kakhulu kwandisa ukuphila kwebhetri futhi kwehlisa Ukuphumula lapho silungisa izinto. Endaweni ukukhiqizwa kuba - esibalulekile. Njalo engahlelelwe umugqa ukukhiqizwa stop kuholela ukwehla ekukhishweni umkhiqizo wokugcina, okuyinto, Yebo, njengoba kubonakala kula izindleko zawo.

Njengoba isibonelo, cabanga uhlelo encane lapho isilawuli lokushisa isetshenziswa. Uhlelo lokulawula has okokufaka ezimbili - inkomba nempendulo amasignali. Lokucabanga ukuthi isiginali Kwakudingeka avumelanise isabelo ipharamitha inani elithile. Njengoba lisetshenziswe lokushisa isilawuli kancane kancane kwandisa samanje izakhi Ukushisa kuya esiphezulu. Ngemva kwalokho ngeke uqhathanise isignali impendulo ngalo kanye nenombolo yeriferensi. Athi uhambisane - ngeke bushelelezi off into. Ngokuvamile e izinhlelo ezifana ahoxise hysteresis babeka / ukuvala - lokhu kuyadingeka ukuqinisekisa operation esitebeleni of ohlelweni lonke.

Ngaphambili, ukuze ushintshe main wesifunda contact heater izifunda esetshenziswa ube nenamba yokuntula: waba ukwanda okukhulu kwezincwadi umthwalo lamanje, bafake okusheshayo oxhumana nabo, njll Modern lokushisa isilawuli ilawula amandla amamojuli esekelwe thyristors, triacs, IGBT-transistors, njll iyunithi ngalinye has izici zayo siqu ekuphathweni ukuthi futhi kufanele kubhekwe lapho ukuklama idivayisi.

amahle ukulawula izindawo enamandla ukukhiqizwa, isibonelo, lokungeniswa amaziko, isilawuli thyristor lokushisa. I element has ukusebenza kakhulu, futhi kahle ngesikhatsi operation nge umthwalo resistive. Ngo ukuphathwa ezinye izinhlobo imithwalo, lezi amadivaysi ezintsha ngesikhathi esisodwa kancane kancane ukuhoxa izikhundla zawo izikimu zanamuhla.

Ngesinye isikhathi kuyadingeka ukusebenzisa Regulator lokushisa. Isibonelo esihle kulokhu singasebenza njengesisekelo esiqinile sokufinyelela idivayisi elincane ukuthi usebenza e-sauna. Njengoba ubona, kukhona isignali inkomba (e degrees Celsius). Impendulo kulokhu le yengeza izitshengiselo ezivela kwamanye inzwa lokushisa okuyinto ngokufanele ngaphakathi sauna. Kungokufanayo imisebenzi isimiso futhi izinga lokushisa lamanzi isilawuli, ushintsha kuphela uhlobo inzwa esetshenziswa. Amadivayisi anjalo nazo asetshenziswa ekukhiqizeni (Yiqiniso, banalo ikhono olukhudlwana).

Njengoba sekunama-ezintsha amandla izingxenye esekelwe amadivayisi Semiconductor uthatha kancane kancane izikimu "ubudala". Zihlala zinjalo ukulawula Imigomo esekelwe phezu kwayo lezi amadivaysi isebenze kuphela.
