Siyini isizathu se-oxidation kanye nokwenza mnyama kwamatheminali?
Inqubo yokusebenzisa izinkampani ezibulalayo ivame ukuholela ekwakhiweni kwezinhlobo ezahlukahlukene zezinkinga, njengokuthi kithi kungaba yi-oxidation evamile emnyama, uma i-terminal oxidation emnyama ngaphandle kuzoba nongqimba lwezinto ezifana ne-soot, e-oxidized, kanye ukwakheka kwezinto ezimnyama, ukusebenzisa i-sandpaper noma ifayela ukuze ugaye.
Njengoba sonke sazi, amatheminali anezinga elikhulayo lokuzenzakalelayo kwezimboni kanye nezidingo zokulawula izimboni ziya ngokuya ziqinile, futhi inani lamatheminali liyakhuphuka kancane kancane. Ngokuthuthuka kwemboni ye-elekthronikhi, ukusetshenziswa kwamatheminali kuyanda, nezinhlobo eziningi kakhulu. Amatheminali ukuze kube lula ukuxhumana kwezintambo kanye nezicelo, yingxenye yophawu endaweni yepulasitiki evikelayo yegolide, iziphetho zombili zinezimbobo ezingafakwa ocingweni, futhi kunezikulufo zokubopha noma ukuxegisa, njengezinto ezimbili. izintambo, ngezinye izikhathi zidinga ukuxhunywa, ngezinye izikhathi zidinga ukunqanyulwa, kulokhu ungasebenzisa amatheminali ukuze uwaxhume futhi anganqanyulwa nganoma yisiphi isikhathi, ngaphandle kokuwashisela noma ukusonta ndawonye, kulula kakhulu futhi kuyashesha.
Kodwa-ke, ngezinye izikhathi kungase kube nalolu hlobo lokuxegiswa kwetheminali okubangelwa ukumelana nokuxhumana nomphakathi ukuba kukhulu kakhulu, ngaleyo ndlela kudale ukushisa ngokweqile; amatheminali awakhululekile, kodwa ngenxa yesekhethi ngenxa yezizathu ezithile ezingaziwa zemvelo kanye nokushisisa okwedlulele, njengokuhlinzekwa kwamandla kagesi wesistimu yokuphakela iphezulu kakhulu, noma umthwalo ufushane, okuzophinde kubangele i-oxidation yokugcina nokuba mnyama. Ngakho-ke, izimbangela zezinkinga ze-oxidation kanye ne-blackening yamatheminali zihlanganisa amaphuzu amabili alandelayo.
1.i-voltage iphezulu kakhulu. Ingabhekwa kusuka emthonjeni, i-voltage yesibili ye-voltage ye-transformer ebhokisini lokusabalalisa - i-voltage yemishini yamandla ngayinye. Amasokhethi angaphinda abe ne-assembly fastening kanye ne-locking fastening. Ukuqiniswa komhlangano kungadlala okuqinile okugxilwe ebhodini le-PCB, ukubopha ukuvala kungafakwa ngemva kokuphothulwa kokukhiya umama kanye nesokhethi.
Izinhlobonhlobo zemiklamo yesokhethi ziyatholakala ukuze zifane nezindlela ezihlukene zokufaka zabesifazane, ezifana nezivundlile, eziqondile, noma ezine-engeli ku-PCB. Zombili izikali ze-metric nezintambo ezijwayelekile ziyatholakala.
2. iphutha eliphansi. Ungaphinda uhlole kusuka ku-transformer lapho, bese uye ebhokisini lokusabalalisa. I-grounding kufanele ibekwe phansi, kuyilapho izintambo zesigaba esivamile kufanele zikhishwe emaphutheni aphansi. Ingavulwa ngemitha evalekile noma ithebula elinyakazayo ukuze likalwe, kanye nezilinganiso zesegimenti, zama ukukala kuphela izingxenye zezintambo, izintambo, ama-circuit breaker, amaswishi, nezinye izintambo zikagesi nokusabalalisa, kunzima ngempela ukuhlukanisa icala, ikhipha amathuluzi abuthakathaka, okokusebenza kokuzwa, ama-fuse.
Isihluthulelo sokumisa phansi siwukuba ukumelana nomhlaba kufanele kube kuncane, kuyilapho indawo yokuxhumana kufanele ibe nkulu. Owokuqala angaqinisekisa ukuthi indawo okugxilwa kuyo inamandla aseduze namandla omhlaba aphansi ngangokunokwenzeka, okungase kuvimbele ukuthi ucabange ngokuduma, noma umbani osuka entanjeni yaphansi oyolandela, ugijimele ekutholakaleni kwamandla kagesi. isifunda.
Lesi sakamuva singaqinisekisa ukuthi kukhona umthamo owanele wokuhlinzeka ngesiteshi samanje esinephutha, kufaka phakathi amaphutha ombani noma ama-short-circuit njalonjalo. Ngenxa yokuthi inqubo yokwakhiwa kwangempela isekelwe emfundisweni yobuchwepheshe besimanje kanye nezinguquko nezinguquko kwezobuchwepheshe, le ndlela yokumisa ingenzeka, enhle noma embi, kodwa futhi ukubona ukuthi ukucaciswa okujwayelekile okusha kanjani.
Ukulimala okubi kokuxhumana nokuphela
Amatheminali kwinqubo yokufaka, uma kukhona uxhumano olubi, luzothinta ukusetshenziswa okujwayelekile kwabantu, futhi kulula ukwenza i-oxidize emnyama.
Ukufakwa okulungile nokusetshenziswa kwamatheminali kungaqinisekisa ukuthi ubunjiniyela bukagesi ukugwema ukuvela kwamaphutha ezintambo, ngakho-ke, ukufakwa kwamatheminali kubaluleke kakhulu. Uma kukhona ukuntuleka kwezindlela zobuchwepheshe ezifanele ohlelweni lokwakha, ukusebenza kahle kwamatheminali ngeke kukwazi ukuthola ukudlala okugcwele. Ngakho-ke, kufanele kuqashelwe ukuhlukaniswa okuqondile kwama-terminals, ngoba izinhlobo ezahlukene zezindlela zokufaka ezihambisanayo zihluke kakhulu. Isibonelo, uhlobo lwe-plug-in ludinga ukufakwa kahle ukuze lunikeze ukudlala okuphelele ekusebenzeni okufanele. Uhlobo lwe-Terminal block kanye nohlobo lokuqhathaniswa okuningi, ukufakwa kufanele kusekelwe esimweni sangempela ukukhetha indlela efanele.
Lapho ufaka, kufanele ukhethe amatheminali anekhwalithi efanelekile ukuze ugweme izinkinga zokuphepha ezibangelwa imikhiqizo engafanelekile. Uma ufaka ama-terminals, kufanele ukhethe imikhiqizo yesayizi efanele ngokusho kwesimo sangempela, futhi usakaze ngokufanelekile umthwalo wezigaba ezintathu, hhayi nje ukucabangela umnotho kagesi, kodwa futhi ukuqaphela ukuphepha kukagesi. Lapho ufaka ibhulokhi yetheminali, indawo yokuxhumana kufanele ipholishwe kahle futhi igcotshwe nge-conductive paste, ukuze ibhulokhi yetheminali kanye nesiqeshana esithinta umthofu kube kuhle ukuhlangabezana nezimfuneko zamandla okuxhuma okubili nokusebenza kukagesi ukuze kuncishiswe ithuba lokukhiqiza ukushisa. . Indlela yokuba nomthelela ekuphepheni kwemigqa ehlobene netheminali, idinga ukulungiswa ngokushesha. Kufanele ihlolwe njalo ngekhebula eliholela emugqeni wokusabalalisa, ukuze kuncishiswe amaphutha e-peripheral kanye nemigqa yokusabalalisa yezingozi zemvelo.
Uma i-terminal block ilimele lapho isetshenziswa, ngeke ikwazi ukusetshenziselwa ukukhiqizwa kwangempela. Yiziphi izimbangela zomonakalo? Uma intambo ehlutshiwe yebhulokhi yetheminali iyimfushane kakhulu, indawo ye-spring crimping izoba yincane kakhulu, okuzobangela kalula ukukhipha okusobala. Ukuze ukhumule, akufanele nje ube nesipiliyoni sokusebenza esicebile, kodwa futhi ufakwe ithuluzi elikhethekile lokukhumula ukulungisa ubude bokuhlubula. Amatheminali anohlu oluqinile lwezidingo zendawo enqamulayo yocingo. Uma ingahlangabezani nezidingo, izintambo zocingo ngeke zikwazi ukufakwa ngokugcwele emigodini yama-terminals, okuholela ekunciphiseni kwe-conductivity kanye nezinkinga ezifihliwe.
Ubude be-crimp nokuqina kwebhulokhi yetheminali kudinga ukuhlangabezana nezidingo ezifanele. Uma ucingo luncane kakhulu, ngenxa yokwehlukanisa phakathi kocingo nendawo yokuxhumana kanye nokucindezelwa isikhathi eside kocingo, ukuqhutshwa kocingo kuyawohloka, ngaleyo ndlela kushise amatheminali.
