Ombane Tester: manual. Yintoni na umvavanyi ombane ukuze bathenge Tips

Ukusebenza kunye zombane, iingcingo ezihamab phantsi kunye nokufakelwa iimveliso ezikhoyo lubeka emngciphekweni ukuze ufumane yokwenzakala yombane. Isizathu soku ilula - intshukumo kwe amasuntswana amacala umqhubi ayikwazi kungabonwa ngeliso lenyama. Ngoko, ngexesha lofakelo, ukusebenza kunye nokugcinwa kwezixhobo zombane kufuneka kusetyenziselwa uvavanyo le ngumhloli ombane Ekwaziyo ubuncinane nje kubonisa ubukho enefuthe, nokuba ngaphandle yokulinganisa eyona ixabiso layo.

imfuno ebalulekileyo

Ombane Tester - isixhobo sombane ephathwayo eyenzelwe ukubonisa ubukho elinokubakho kwiindawo conductive. Ubonelelo ngombane zonke iingcingo ziyingozi ukuchukumisa. Ngoku ukulwa abo isigaba langoku, kodwa kwiqanda okanye emhlabeni wire ukholosile. Noko ke, kukho amathandabuzo.

Ukuze siqonde oko kuyimfuneko umvavanyi ekhaya-ombane, indlela elula ukunika iqela lemizekelo. Masithi kukho imfuneko kwi grinder (grinder), ngelo xesha wanikela ummelwane. asetyenziswa imifuziselo Nakuba kunjalo, apho lwezindlu yenziwe ngentsimbi. Indlela ukukhangela ukuba iziphaluka lwangaphakathi bubuhle, kwaye iqokobhe akukho kwempixano? Ukusebenza isixhobo esinjalo, emva kokuba sele uyitshekishile - impela gembula. Okanye, umzekelo, kufuneka ukutshintsha iglowubhu yesibane kwi isibane, ibhalbhu yeglasi iwisiwe, kwaye kuphela plinth wahlala iCartridge. Kholwani ngogesi ukwenza iingcingo, iswitshi waphula ngokwenene kumqhubi lesigaba kunye non-zero, yaye ngenkalipho bajije cap? Kambe ke kuyathandabuzeka! Imizekelo ezinjalo emininzi. Ekubeni tester wayo ombane lakhe, ungasoloko ngokukhawuleza zesayithi kolu fakelo. Ukongeza, imifuziselo lunzima kakhulu ukuvumela zokulinganisela ixabiso yangoku.

iimpawu ezingundoqo

Ukuze uqinisekise ukuba ubukho amandla (isigaba), akukho mfuneko yokuba uchithe imali yokuthenga izixhobo ezixabisa. Le ombane tester ilula - Isalathisi screwdriver. Ngaphakathi umzimba wayo ngaphaya unalo isibane elincinane Ikhanyisa xa angamchukumisi umntu Ulwamvila kwiindawo phantsi isakhono.

Njengoko umvavanyi ukukhangela le ombane? Kwicala eliphezulu Heating umqheba unalo metal ekhethekileyo "idenariyo." Ukujonga icandelo chain kufuneka usebenzisa screwdriver ukuyiphatha umkhondo uvavanyo, kunye ngomnwe - ". Kopecks ezintlanu" a Akubuzwa lel xa ayikwazi bemchukumisa. Ukuba esisigaba ukho, kusibonisa ukukhanya ngaphakathi screwdriver. Igama yesibini ii-screwdriver - ixhokonxa. Ezi nkundla ke zenzelwe ukuba yombane ukuya ku 250 V.

Ayikhuthazwa ukuthenga imodeli yayixabisa, njengoko kwimeko kohlulwe resistor lwangaphakathi okanye iimpazamo kwisikimu ungafumana ukukhatywa ngumbane. izisombululo thuthu musa ukuba ukudibana ngqo kunye nesabelo wesekethe. Imiphumela screwdriver, kufuneka nje ukuba zichithe ngaphezu nombhexeshi. Eyenzelwe yombane ukuya ku 600 V. Ukongeza, eminye imifuziselo zixhotyiswe nge Ebonisa ezivakalisa ixabiso yangoku.

Kukho iimpucuko musa zifuna touch yeminwe kwi "kopecks ezintlanu." Uyakwazi ngaphandle naziphi na iingxaki kuthenga ngumhloli ombane. Imiyalelo ukuba kufuneka ifundwe. Oku konga kuphela iyunithi evela umonakalo, kodwa kuya kukhusela umntu.

screwdriver ombaxa

Ngelo xesha linye izixhobo ngentla ziwuphose kakhulu ezizodwa. Ukuba ufuna njalo, umzekelo, ukuba enze umsebenzi olula - Ukungeniswa, yinto engento ngenxa ubukho kwipali enye kuphela. Kulo mzekelo, kufuneka sinikele ingqalelo tester phambili ngakumbi - isalathisi kabini ombane aphantsi. Ngokwemo, oko kungenziwa xa kuthelekiswa screwdriver ezimbini, ucingo lonxibelelwano. Le ombane eliphezulu ngokuvunywe 1 kV. Ixabiso - evela engange-100.

Cinga ukuba ukulinganisa indlela umvavanyi ombane kule klasi. Imiphumela-electrode enye imfuneko ukuyiphatha isiphaluka phantsi site uvavanyo, kunye nezinye - ". Umhlaba" kwi Oku kube naliphi umqhubi emhlabeni ukuze enokuba yingozi oko kungena ngefoni. Ukuba isibane ikhanyisa ngaphakathi emzimbeni, oku kuya kuthetha ukuba kukho imimoya endaweni. Ukuba ufuna Ukungeniswa ekufuneka igalelwe probe omnye kwisigaba omnye umqhubi, kunye nezinye - enye. Ukuba esisigaba kwi iingcingo igama elifanayo, ngoko akukho ebonisa. imifanekiso elula ebonisa isibakala lobukho lesigaba nzima nazo ziqulathe enye LED izibambo ezininzi, chweba yayo ukumisela ixabiso ombane.

Isalathisi

Iklasi elilandelayo izixhobo ezinjalo Iimpawu ombane. Imodeli esaziwa kakhulu "Iinkcukacha" kumenzi Ukrainian. iindleko kuqala engange-400. Ngokwemo, le Abahloli akuphuhlanga kakuhle abafanekisela screwdriver kabini, kodwa abe imisebenzi ephambili emininzi. Ingakumbi, zinokusetyenziswa ukufumanisa ukuba isigaba uqikelelo malunga inqanaba ombane ukusuka ukukhutshwa LED, khangela isidima nombhexeshi. Ngaphakathi ikuyo loo ekondensa, ekufuneka pre-abekwe ityala ngokuthi kuphando touch ku-220 / 380V imizuzwana 20-30.

Indlela yokufumana ucingo live

Cinga ngendlela umvavanyi ukukhangela le ombane. Enye ixhokonxa zecebo kufuneka ukubamba ufakelo site kuhlolwa, kunye nobhontsi - Ph ukuya electrode emzimbeni. Ukuba LED ehambelana ikhanyisa, ngoko umqhubi ke amandla. Noko ke, kukho caveat, olwaziwa kakuhle kakhulu kubantu akwazi ukusebenza indlela umvavanyi ombane kule hlobo. Ihlala yokuba isigaba zovavanyo besebenzisa Ph akusoloko ilungile, njengoko ubungqina sinokuchaphazela uphazamiseko ukusuka kufutshane ababhexeshi yangoku-ethwele. Ukuze acacise, kukho iingcingo ezibekwe ngecala, enye yazo na amandla kunye nezinye amandla. Ukuba awuyazi ukuba ukusebenza lo ombane tester njani ngokweenkcukacha, ukuhlola zombini abaqhubi ngokubabamba kunye Ph electrode ujika ukuba ngokutsho ebonisa ukuba zombini sigaba. Noko ke, akunjalo. Nje de-amandla uqhutyelwe amandla electromotive phantsi yintshukumo asendle electromagnetic. Lufikelela amashumi nje ezimbalwa volts, kodwa kuxhomekeka kwisixhobo yaye ayibonisi umsebenzi wayo. Kwiimeko ezinjalo, xa uyathandabuza, kufuneka wenze ngenye indlela: touch probe kwindawo luyaphicothwa, kunye nezinye - ingongoma nisekelwe kwaziwa. Phambi LED umqhubi kwisigaba zikhanya kwaye ubonise ixabiso elisondeleyo 220 V. Ngendlela, ukuba ufikelelo ombane ontlantlu-ntathu, khangela indawo ungakwazi ngokubabamba nje kuphela kwi "umhlaba", kodwa nakwezinye izinikezeli isigaba. Oko kuyafana ukuphunyezwa kwenyathelo kokumana. Kwimeko phambi ombane kwi isabelo thinta kwisigaba heteronymic kuya kukhokelela ekubeni ukukhutshwa kwe-LED 380 V.

Izitenxo zesalathisi se tester

Le iinkcukacha ithi ukuba ngoku ayahamba isixhobo wesekethe ukutshekisha umthamo 220 ayikho ngaphezu kwe-10 Ma. Oko kukuthi, ukuba bachukumise enye kuphando ukuya kwisiza mveliso, ephantsi ombane, i ammeter elidityaniswe kwenye uphenyo, kulapha ngentla ziya kubonisa ukubaluleka lwangoku. Enyanisweni, oku lixabiso eziyingozi (100 Ma - esibulalayo), xa kusenziwa kokuchukunyiswa isandla kunokwenzeka, kodwa logama nje zichanekile busebenze yangaphakathi ifowuni.

Ukuqalisa kunye "contact"

Zonke izisombululo apho iiyunithi ezimbini amaqhina oqhagamshelwano yi ucingo, yingozi. Enye ethile zabo - amathuba ngokonakalisa umqhubi osuka kwi ingqibelelo iqokobhe ebonakalayo. Ngoko ke, xa spool kwisigaba nge Ph Kucetyiswa probe kwe block apho i electrode esebenzayo ibekwa. Kulo mzekelo, i-LED iya kusebenza, nokuba kwicingo yonakele. Noko ke, ngaphambi kokwenza imilinganiselo kufuneka ukwazi ukuqhagamshela ifowuni kwinethiwekhi kwaye yibambe 20 - ngeli xesha ebizwayo umthombo wamandla lwangaphakathi. Ngoko ke kufuneka ukuba uxhumane nabanye ixhokonxa nganye. Ukuba ucingo, i-LED izibane phezulu "uvavanyo."

isixhobo jikelele

Ukongeza zonke ezi zixhobo, kukho uhlobo olunye - multimeters. Mhlawumbi lo umvavanyi ombane kakhulu ogqibeleleyo. Indlela yokusebenzisa ngayo, ngoku siza ukuchaza. Iindleko onobuhle ezingabizi kakhulu iqala engange-300. Umsebenzi uchazwe kule ncwadana ethi, apho kufuneka khona. Ukuba sithethe ekuhloleni ombane, omnye cingo kufuneka idityaniswe izibuko COM, enye - to V. koko, wabeka iswitshi ukuya 750 AC (alternating uhlobo lwangoku, umda we-750 V) imo ngaphandle kwebala ixhokonxa kwi "umhlaba" yaye kummandla luyaphicothwa.

iziphumo

Ngenxa yoko, akunakwenzeka ukuba ukunika iingcebiso ezicacileyo ukhetho yesixhobo. Yonke into ixhomekeke uluhlu lwemisebenzi zicwangciselwe ukuba ukuqwalaselwa. Ukuba kukho imali engaphezulu iya kuba ngcono ukuthenga multimeter iphela.
