Nzira yekuedza sei dunhu rinoputika ne multimeter
Zviri mukati
Chimwe chezvinhu zvinonyanya kukosha zvemagetsi mumagetsi epamba yako madhigirii edunhu.
Zvishandiso zvidiki izvi zvinokudzivirira kubva kunjodzi dzinouraya uye zvishandiso zvako zvakakura kubva mukukuvadzwa kusingagadzirike.
Ikozvino, pamwe unofungidzira kuti imwe yemagetsi ako emagetsi akakanganisa uye haadi kufonera nyanzvi yemagetsi, kana iwe unongoda kuziva kuti izvi zvikamu zvemagetsi zvinoonekwa sei kuti zvine kukanganisa.
Chero nzira, wauya kunzvimbo chaiyo.
Iri nhanho nhanho gwara rinokudzidzisa maitiro ekuyedza dunhu rinotyora ine multimeter.
Ngatitangei.
Chii chinonzi circuit breaker?
A circuit breaker inongova magetsi emagetsi anodzivirira dunhu kubva pakukuvadzwa ne overcurrent.
Iyi chinja chemagetsi, chinowanzowanikwa mubhokisi remagetsi remagetsi, rinochengetwa panzvimbo ne screw kana latch.
Overcurrent ndiyo apo kugoverwa kwezvino kunodarika simba guru rakachengeteka remudziyo wawakagadzirirwa, uye izvi zvinounza ngozi huru yemoto.
Iyo yedunhu breaker inobvisa mabatiro ayo kana iyi overcurrent ikaitika, ichimisa kuyerera kwezvino kune mudziyo.
Kunyange zvazvo ichishanda chinangwa chimwechete se fuse, haifaniri kuchinjwa kana yaputika. Iwe unongoigadzirisa uye woidzorera zvakare kuitira kuti irambe ichiita mabasa ayo.
Nekudaro, zvikamu izvi zvinotadza nekufamba kwenguva uye kuchengetedza mudziyo wako kwakakosha. Nzira yekuziva sei muparadzi wedunhu?
Nzira yekuziva sei kana circuit breaker inokanganisa
Pane zviratidzo zvakawanda zvinoratidza kana dunhu rako rakaipa rakaipa.
Izvi zvinobva pakunhuhwirira kunopisa kunobva kudunhu rinotyora kana magetsi emagetsi, kupisa mavanga pane chinotyora cheketi pachayo, kana chedunhu chinopisa zvakanyanya kusvika pakubata.
Anokanganisa wedunhu anotyora zvakare anofamba nguva zhinji uye haagare ari mukugadzirisa modhi kana akamiswa.
Zvimwe zviratidzo hazvioneki pakuongorora kwepanyama, uye apa ndipo apo multimeter inokosha.
Zvishandiso zvinodiwa kuti uedze chivharo chedunhu
Kuti uedze wedunhu breaker iwe uchada
- multimeter
- Insulated magirovhosi
- Seti yema screwdrivers ega
An insulated tool ichakubatsira iwe kudzivisa kushamiswa kwemagetsi.
Nzira yekuedza sei dunhu rinoputika ne multimeter
Kuti uedze zvakachengetedzeka mabreaker breaker, isa multimeter yako kune ohm kuseta, isa iyo dzvuku bvunzo lead pane yemagetsi terminal yedunhu breaker, uye dema bvunzo inotungamira pane iyo terminal inobatanidza nepaneru. Kana iwe ukasawana yakaderera kuramba kuverenga, iyo yedunhu inotyora uye inoda kutsiviwa..
Kune mamwe matanho ekutanga, uye iwe unogona zvakare kumhanya bvunzo yevoltage pane wedunhu breaker. Zvose izvi zvichaparadzirwa.
- Isai simba redunhu
Kuyedza kuramba kwevanopwanya matunhu ndiyo nzira yakachengetedzeka yekuyedza madhiraivha ekukanganisa nekuti haudi simba rinomhanya nemavari kuti uongorore nemazvo.
Tsvaga iyo main kana general switch pane yemagetsi pani uye woishandura kune "off" chinzvimbo. Ichi chinowanzo chinja chakakura chiri pamusoro pebhokisi.
Kana izvi zvangoitwa, enderera nemaitiro anotevera nhanho nhanho.
- Isa yako multimeter kune ohm kuseta
Shandura dhiraivha kune ohm chinzvimbo, iyo inowanzo ratidzwa nechiratidzo Omega (Ω).
Nepo iwe uchigona kushandisa mita yekuenderera mberi modhi kuti uedze kuenderera mukati memucheki wedunhu, iyo Ohm yekumisikidza inokupa yakawedzera mhedzisiro. Izvi zvinodaro nekuti iwe unoziva zvakare mwero wekupokana mukati mayo.
- Bvisa dhiraivha yedunhu kubva kubhokisi rebreaker
Iyo switch inowanzo batanidza kumagetsi epaneru bhokisi kungave kuburikidza ne snap-in slot kana kuburikidza nesiruu. Bvisa iyo kubva pane switch kuti ufumure imwe terminal yekuyedza.
Panguva ino, fambisa switch yebreaker kune "off" chinzvimbo.
- Isa multimeter inotungamira pane circuit breaker terminals
Zvino isa iyo tsvuku yakanaka yekuyedza inotungamira pane switch yemagetsi terminal uye dema negative bvunzo inotungamira pane terminal pawakabvisa switch kubva kubhokisi rekuchinja.
- Reta zvabuda
Fambisa shanduko kune "pa" chinzvimbo kuti upedze dunhu uye tarisa kuverenga kwemamita.
Kana iwe ukawana zero (0) ohm kuverenga, switch iri mumamiriro akanaka uye dambudziko rinogona kunge riri newaya kana bhokisi rekuchinja.
A good circuit breaker kazhinji ane kuramba kwe 0.0001 ohm, asi multimeter haigone kuyedza chiyero ichi zvakananga.
Kune rimwe divi, kana iwe ukawana kukosha kwe0.01 ohms, saka kune yakawandisa kuramba mukati mebreaker uye izvi zvinogona kuve dambudziko.
Kupokana mukati meiyo switch pamusoro pe 0.0003 ohm inoonekwa yakanyanya kukwirira.
Chete nyanzvi dzemagetsi dzinowanzova neyakajairwa chishandiso chekugadzira aya madiki-mayero.
Zvakare, kuwana kuverenga kweOL zvechokwadi kunoreva kuti switch yacho yakaipa uye inoda kutsiviwa. Izvi zvinoratidza kushaikwa kwekuenderera mukati me block.
Iwe unogona kuwana ese aya gwara muvhidhiyo yedu:
Kutarisa voltage mukati memutsigiri wedunhu
Imwe nzira inoshandiswa nenyanzvi yemagetsi kuona matambudziko neanopwanya wedunhu ndeyekutarisa voltage yaiswa pairi.
Iwe hautarisiri kuti breaker ishande zvakanaka pasina kukwana ikozvino.
- Tora Matanho Ekuchengetedza
Kuti uedze voltage mukati memutsigiri wedunhu, unofanirwa kuve neinoyerera inoyerera kuburikidza nayo. Zvechokwadi, pane ngozi yemagetsi uye iwe haudi kukuvadzwa.
Iva nechokwadi chekupfeka magurovhosi erabha uye magirazi kana unazvo. Itawo shuwa kuti ma probes haabatane panguva yekuyedzwa kuti arege kukuvadza chiridzwa.
- Isa iyo multimeter kune AC voltage
Imba yako inoshandisa AC voltage uye huwandu hunoshandiswa hunosiyana kubva pa120V kusvika 240V. Meta inowanzova nemagetsi maviri e AC voltage; 200 VAC uye 600 VAC.
Seta iyo multimeter kune AC voltage renji iyo inonyanya kukodzera kudzivirira kuridza fuse yemultimeter.
Mazana mazana maviri akakodzera kana imba yako ikashandisa 200 volts, uye mazana matanhatu akakodzera kana imba yako ikashandisa 120 volts. AC voltage inoratidzwa pamamita se "VAC" kana "V~".
- Isa iyo multimeter probe pasi uye shandisa iyo terminal
Ikozvino switch yacho yave nesimba, isa multimeter's positive probe pane switch yemagetsi emagetsi uye gadzika chinongedzo nekuisa iyo isina kunaka probe pane yesimbi iri pedyo.
Idzi nzvimbo dzakafanana kunyangwe uri kushandisa maviri-pole circuit breaker. Iwe unongoyedza divi rega rega rega.
- Reta zvabuda
Panguva ino, mita inotarisirwa kuratidza AC voltage kuverenga ye120V kusvika 240V, zvichienderana nehuwandu hunoshandiswa mumba mako. Kana iwe ukasawana kuverenga kwakaringana muchikamu ichi, saka simba rekuchinja kwako harina kukwana.
mhedziso
Miedzo miviri pane yako yedunhu breaker inobatsira kuongorora matambudziko akasiyana. Muedzo wekupokana unoratidza dambudziko neiyo switch pachayo, nepo voltage test inobatsira kuona dambudziko nemagetsi.
Nekudaro, imwe neimwe yebvunzo idzi inobatsira, uye kutevedzera maitiro ataurwa pamusoro apa munhevedzano kunobatsira kuchengetedza mari uye kudzivirira kufonera mugadziri wemagetsi.
Inowanzobvunzwa Mibvunzo
Unoziva sei kana dunhu redunhu richida kutsiviwa?
Iro redunhu rinotsiviwa kana ukaona kukuvadzwa kwemuviri, sekupisa mavanga, kunhuhwirira kunopisa, kana nyaya yacho ichipisa zvakanyanya. Iwe unogona zvakare kushandisa multimeter kuona mamwe asingaonekwe anonongedzera.
Ko dunhu rinopwanya rinogona kupera simba here?
Ehe, wedunhu rinopera simba pese parinofamba. Nzendo idzi dzinowanzokanganisa kutenderera kwayo uye wiring uye zvinozokonzera kuti mudziyo umire kushanda mushure mekufamba 4 (mana) kusvika kushanu (5).
