Ihlola diode ibhuloho multimeter, ngaphandle kokukhipha generator

Bambalwa Abashayeli bazi ziskenwa diode ibhuloho multimeter, futhi ukwazi lokhu kungaba usizo kakhulu. Lo msuka linendima ebalulekile emsebenzini generator, futhi ngenxa ke ibhethri ishaja efanele. Ngokuvamile, uma kukhona noma yisiphi ukwehluleka, abashayeli kanye enophephela imoto yakhe esiteshini. Kodwa ngokuvamile, nje esanele ukuze wenze isheke diode ibhuloho multimeter, ngemva kwalokho-ke sizokwazi ukuxazulula inkinga bebodwa, uzoshiya imali ukuthi kuzodingeka ukuthi ukhokhe ukulungisa leyo mishini. Ake sihlaziye ngokuningiliziwe onjani generator isici nokuthi iquketheni nhlobo.

Kuyini ibhuloho diode? isimiso sayo ukusebenza

Le divayisi ukhonza njengelungu isici ukushaja rectifier. Ukuguqula AC generator isethwe 4 kuya ku-6 diodes, futhi zenziwe wesifunda olulodwa, kubhekiselwa kuye ngokuthi ibhuloho diode. Uqinisile wokuphehla.

Umgomo we operation kwalesi sakhi ilula: ke imigqomo wamanje ezivezwa generator ukuze ibhethri, bese ungaphuthelwa ke kolunye uhlangothi - kusukela ibhethri generator. Kulokhu, kwelinye direction kudala inani elithile ukumelana, benze okuhlukile ukumelana ivame infinity. Uma kukhona iphutha kwebhuloho, electronics semoto izohluleka. Kunalokho, ibhethri izohluleka, futhi ngaphandle kwalo imoto ngeke uqale banal njengoba ukuziqalela ngokwayo lusekelwa ngamandla ebhethri elishajekayo.

Ngenxa yalokho ashaye diode bridge?

Ihlola multimeter diode ibhuloho generator kuhilela kuhlanganise ukucaciseleka zezizathu kwebhuloho diode ehluleka. Isizathu ezijwayeleke kakhulu - ekuqongeleleni amanzi ngaphakathi. Ngokuvamile emva ukuwasha izimoto noma ukushayela ngokusebenzisa ibhuloho amaxhaphozi kungaba zishe.

Eyesibili isizathu - the polarity reverse terminals ibhethri. Lokhu kwenzeka Ukulekelela lapho bengelutho yokuxhuma ishaja nebhethri. Yiqiniso, kungase kube izimbangela eziyinkimbinkimbi nokutubeka kwaleli bhuloho, kodwa ngokuvamile kwenzeka, enye yalezi zizathu ezimbili. Ngakho-ke, zama ukugwema ukushayela ngokusebenzisa amaxhaphozi ezijulile futhi Ukushaja ibhethri kahle.

Kusho kwebhuloho diode ashisiwe kanjani?

Uma kukhona izinkinga ibhethri, ngokuyinhloko kudingekile ukwenza isheke multimeter diode ibhuloho. Ibhethri ezixhunywe ngokuqondile leli bhuloho. Uma lilimele kukhona 2 ongakhetha yilezi: wamanje akusho ukuya ibhethri noma uya, kodwa ngezinga eliphakeme kakhulu. Lokhu kungabangela ibhethri ukubilisa.

Ngakho-ke, lapho kudingeka ukuxazulula ngokushesha okukhulu kuvela izinkinga nge kwebhuloho. Uma kungenjalo, kufanele athenge ibhethri elisha, futhi akuyona ezishibhile. Ngakho-ke kungcono ukuthi ube ne-umqondo wokuthi isheke diode ibhuloho multimeter ukuba 2110 nezinye onobuhle Vaz. Okungenani kunezinhlobo nezindlela zokuhlola ezimbili: usebenzisa multimeter noma ezivamile ukukhanya Isibani. Ake sixoxe ngezizathu.

Hlola isibani

Okokuqala - Susa kwebhuloho diode kusuka generator. Nokho, esimweni isibani ngaphandle lokhu ungakwenza. Thatha kwebhuloho zesikole ithinta ukuba terminals ibhethri. Qiniseka ukuthi uqinisekise ukuthi yoxhumana naye njalo uqine. Manje thatha isibani kanye contact yayo (plus) uthinte ibhethri plus.

Manje yanjalo uthinte nezinye pin diodes isibani oxhumana nabo, sabe sesiya e-ukuziqalela emazombezombe uxhumano. Uma isibani luthungelwa, kusho ukuthi bhuloho kwakuyisazi "ile" futhi ngenxa yalokho okungenamsoco. Manje, uma izigaba wesifunda uxhumeke nge eyodwa diode, kungenzeka ukuhlonza ingxenye okuyiphutha futhi esikhundleni salo esisha.

Uma kukhona isidingo ahlole wesifunda ibhuloho, ibhuloho lokususa "nokujikijela" ukuze ibhethri plus. Khona-ke, xhuma isibane ibhethri plus plus. Manje khulula isibani oxhumana uxhumeke kwi-izakhi njengoba kuchaziwe ngenhla. Ukukhanya kulokhu kufanele kube njalo. Uma-ke akabi noma ukusha dim ukukhanya, evulekile wesifunda diodes kwenzeka.

Ihlola multimeter diode kwebhuloho

Njengoba esedlule yokuhlola indlela nge isibani, kulesi simo futhi kubalulekile ukususa ebhulohweni besuka generator. Lapho ehlola kwebhuloho multimeter diode diode ngalinye ihlolwe ngokwehlukile. Okokuqala sidinga unike amandla imitha "ikhalisiwe" Imodi, kodwa uma umbuso okunjalo akukhona ke nje ukusetha ukumelana 1 Ohm. Kule modi, kuvalwe oxhumana ezimbili izokhala.

Ibhuloho ihlukaniswe yaba izingxenye ezimbili: diodes asizayo namandla. Ihlola diode ibhuloho multimeter Vaz-2114 kanye nezinye brand wenza kokubili ezingxenyeni okufanayo. Isimiso simiswe ngalendlela lelandzelako: ibhethri eziqhutshwa diode isiqondiso sizobonisa ukumelana elilingana ohms abangamakhulu amaningana, ukumelana kolunye uhlangothi azothanda okufanekisa ingunaphakade.

Xhuma iphenya multimeter ukuze pin ngamunye diodes. Futhi uma ithuluzi sizobonisa value ehlukile ukubaluleka ngemuva kokushintshwa izindawo uphenyo, bese lokhu kubonisa ukuthi diode zishiswe. Lo msebenzi kumele kwenziwe ukuze diode ngamunye.

Uma ukumelana sincane kakhulu

Eyesibili kukho lapho ehlola multimeter diode ibhuloho generator Vaz-2109 kanye nezinye onobuhle kufaka ukubonakalisa zero amagugu. Lokhu kusikisela ukuthi kukhona wesifunda evulekile. Uma kufundwa iseduze oholayo (ukumelana aphansi kakhulu), kusho ukuthi i-diode siphukile. Imitha njengoba idivayisi Ukuhlolwa ikuvumela ukuba ucacise kahle ukuthi uhlobo diode awahlelanga, futhi ukucacisa uhlobo ukwehluleka. Uma usebenzisa isibani imayelana okufanayo, nokho kube ababuthakathaka Ukushaja catch zamanje ukusebenza efanele nzima. Ngakho-ke, ukusetshenziswa imitha Kunconywa, kodwa uma kungenjalo, khona-ke ungakwazi sizame ukuthola iphutha nge abavamile ukukhanya isibani.

Nokho, inzuzo kuphela isivivinyo Isibani yokuthi kokwenza ibhuloho diode ne generator ayidingekile. Kodwa ngaphandle kokukhipha generator abakwazi hlola multimeter diode ibhuloho. Ngaphandle kokukhipha generator, awukwazi ukudonsa off. Kube kufanele isebenze izingxenye ngazinye, kodvwa lisiniketa ticondziso yalokho esinembile.

Phezu ukuthola we diode-non-ukusebenza ke esikhundleni esisha. Yenza kube lula ngosizo insimbi nokunamathisela ngomthofu. I diode kakhulu efanayo kuwufanele penny, bathengisa ngasiphi esitolo izingxenye auto. esikhundleni sakhe futhi akuyona into enkulu, futhi kungenziwa ngokuzimela.

isiphetho

Ayikho into elukhuni kule nqubo akukho. Uma ucishe ujwayelene electronics wazi kanjani ukusebenzisa multimeter, hlola bese ushintsha diodes okuyiphutha ongawaphatha. Ngenxa yalesi akudingeki uxhumane esiteshini inkonzo, lapho isidingo imali futhi ngibheka yonke esengeziwe zokulungisa.

Zonke izici ezidingekayo ukuze ukulungisa kwebhuloho itholakale ukudayiselwa. Yebo, futhi ngokuvamile engabizi diode ibhuloho, kuphela kungaba nezinkinga ekutholeni ibhuloho generator ezithile imodeli ezingavamile.

Ekugcineni: uma kukhona okungalungile ibhethri, uzobe unenhlanhla uma kuyoba imbangela ibhuloho diode. Kungashiwo, Consumable, okuyinto ebangela isikhathi ukushintsha ngezikhathi ezithile. Kodwa into lapha - isikhathi ukuthi iyini ngempela inkinga lize sasithinte ibhethri uqobo.
