Nzira yekuona Neutral Wire Uchishandisa Multimeter (Matanho mana)
Zviri mukati
Kunzwisisa kwekutanga kwemhando dzakasiyana dzewaya kunogona kubatsira zvakanyanya. Semuenzaniso, hauzive pauchazoda hunyanzvi uhu kune DIY imba chirongwa. Saka, nhasi tichakuudza kuti ungazviita sei.
Iwe unogona kuona iyo isina kwayakarerekera waya uchishandisa multimeter. Mushure mekuisa iyo multimeter kune yakanyanya voltage kukosha, unogona kuona nyore waya isina kwayakarerekera uchishandisa dema uye tsvuku bvunzo inotungamira yemultimeter.
Mhando dzakasiyana-siyana dzedunhu waya
Kune mhando nhatu dzewaya dzaungasangana nadzo kumba. Naizvozvo, kana uri kuronga kugadzirisa kana kuongorora, kuva neruzivo rwakakodzera kunogona kuuya kunobatsira.
Live wire: Waya yebrown iyi inotakura magetsi kubva pamagetsi makuru kuenda kune mamwe maturusi.
Ground wire: Inouya muyero kana yegirini. Waya iyi inoitisa magetsi pasi uye nekudaro inodzivirira ikozvino kuyerera kuburikidza neyakapwanyika yedunhu breaker, inozivikanwawo seCFC.
Neutral wire: Iyi waya yebhuruu inotakura magetsi kubva pachigadzirwa ichienda kune magetsi. Nemamwe mashoko, waya isina kwayakarerekera inopedza hurongwa kana cheni.
Cherechedza: Mufananidzo uri pasi apa unogona kutsanangura zvakawanda nezvemhando idzi nhatu dzewaya. Kunzwisisa kwakanaka kwetambo imwe neimwe yemagetsi kunogona kubatsira zvikuru.
Kukosha Kwekwaakarerekera Waya
Kubva pachikamu chiri pamusoro, iwe unofanirwa kuve neruzivo rwakanaka rwemhando dzakasiyana dzewaya. Zvisinei, iyo tambo isina kurerekera chikamu chakakosha chedunhu uye pasina iyo dunhu harizopedzwa. Mune mamwe mazwi, magetsi haakwanisi kudzokera kune ekutanga simba masosi. Saka, kana iwe uchigona kuona iyo isina kwayakarerekera waya, inogona kukubatsira iwe kana uchikwidziridza pani kana wiring.
4 matanho ekuona iyo isina kwayakarerekera waya ine multimeter
Kunyange zvazvo kazhinji waya idzi dzine mavara, hatigoni kuvimba neizvi zvakakwana kuziva waya dzepanyama. Mhinduro yakanakisisa ndeyokushandisa multimeter. Iyo nzira yekutarisa iyo yakasarudzika wire haisi basa rakaoma zvachose. Zvisinei, zvingava nani kana ukazviita nemazvo. Tataura izvozvo, hezvino zvinhu zvinodiwa kuti chirongwa ichi chipere.
Cherechedza: Kune iyi demo, unogona kushandisa yakajairika imba yekuburitsa magetsi. Tichatsanangura zvese nekubuda. Zvisinei, yeuka kuti maitiro akafanana anogona kushandiswa kune chero imwe dunhu.
Zvinhu zvinodiwa: Multimeter, screwdriver, socket, insulated magurovhosi, probe
Danho 1: Chengetedzo Kutanga
Sezvo isu tiri kutarisana nemagetsi, nguva dzose zvakanakisisa kupfeka magirovhosi akavharidzirwa. Zvakare, shandisa probe chero paunoda. Saka rangarira kutevedzera chenjedzo idzi.
Nhanho 2 - Plug uye Multimeter
Bvisa waya dzose dziri nhatu kubva panobuda. Dzimwe nguva ungangoda kubvisa chivharo chepurasitiki chepamberi kuti waya dzibude. Muchiitiko ichi, shandisa screwdriver kubvisa screws uye chivharo chepurasitiki. Dzimwe nguva unogona kubvisa waya pasina kubvisa chivharo chepurasitiki.
Zvino isa multimeter yako kune yakakwirira voltage marongero. Zvakare, sezvo isu tiri kubata neAC ikozvino, huwandu hweiyo multimeter hunofanirwa kuve hwakasiyana. Saka, ita shanduko dzinodiwa usati washandisa multimeter.
Nhanho 3 - Shandisa dema probe
Multimeter yako inofanira kuva nemaprobes maviri; dema dipstick uye tsvuku dipstick. Ivo vanozivikanwawo sevanotungamira. Batanidza iyo multimeter nhema inotungamira kune yepasi waya kana chero chimwe chinhu chakadzika senge pombi yemvura, firiji, kana pombi. Iyo multimeter haifanirwe kuratidza chero kuverenga parizvino. Iye zvino tinogona kutanga kuyedza waya isina kwayakarerekera.
Danho 4 - Shandisa Red Probe
Kuti utarise waya isina kwayakarerekera, bata waya isina chinhu neiyo tsvuku multimeter probe. Ungangoda kuita izvi kune maviri asara waya (kunze kwewaya yepasi). Kana iwe usingawane chero multimeter kuverenga, zvinoreva kuti waya yemagetsi haina kwayakarerekera. Kana iwe ukawana kuverenga, zvinoreva kuti waya inopisa.
Matanho aunofanira kutevera
Tinovimba iwe ikozvino une zano rakanaka rekuyedza iyo isina kwayakarerekera waya ine multimeter. Nekudaro, kunyangwe iwe uri nyanzvi yemagetsi ane ruzivo, pane mamwe matanho aunofanira kutora. Kuti uchengetedzeke, tevera matanho aya nemazvo. (1)
- Pfeka magurovhosi akaiswa insulated uye shandisa probe. Pfeka magirazi ekudzivirira nekuti pane mukana wakakura wekupenya kwemagetsi panguva yebvunzo iyi. Uyewo, iva nechokwadi chekubvisa zvinhu zvose zvesimbi kubva muhomwe dzako usati watanga maitiro. (2)
- Paunenge uchishandisa iyo multimeter, usabata mhenyu nzvimbo dzine magetsi. Semuenzaniso, bata multimeter nezvikamu zverubha.
- Kana iwe uri wekutanga, tanga nemagetsi de-energized system kutanga. Ingogara iri pfungwa yakanaka usati washanda padunhu mhenyu.
- Usamboshanda nedunhu mhenyu apo maoko ako akanyorova. Uyewo, usamira panzvimbo yakanyorova; inogona kukubata nemagetsi.
Inowanzo Bvunzwa Mibvunzo (FAQ)
Nzira yekuziva sei neutral waya uye HotWire?
Chinhu chekutanga chekuteerera kune ruvara. Kazhinji waya isina kwayakarerekera iblue. Ukuwo, waya inopisa, aka live wire, ine brown. Zvisinei, kushandisa mavara kuziva idzi waya dzemagetsi haisi iyo nzira yakanakisisa. Zvichida dzimwe nguva vagadziri vemagetsi vasina ruzivo vanogona kusanganisa ese masystem e wiring panguva ye wiring. Zvakare, vamwe vanogadzira vanoshandisa mavara akasiyana kune idzi waya. Ndosaka. Usatsamira paruvara.
Zvakanakisisa kushandisa tester kana multimeter. Kazhinji, waya inopisa ine voltage ye 220V kana 230V. Kana zvasvika kune isina kwayakarerekera waya, kune 0V mhiri kwayo. Nokudaro, hazvisi zvakaoma kuziva waya.
Chii chinonzi open neutral?
Kusarerekera kwakavhurika kunoitika kana mapoinzi maviri arasikirwa neaya isina kwayakarerekera waya yekubatanidza. Mune mamwe mazwi, hapana hukama hwakarerekera pakati pezvibodzwa izvi. Kusarerekera kwakavhurika kunogona kuvhara sisitimu kana kukonzera kusagadzikana.
Summing up
Zvese zvinhu zvinotariswa, tinogona kutaura zvakachengeteka kuti kushandisa multimeter ndiyo yakanakisa uye yakachengeteka sarudzo yekuona iyo isina kwayakarerekera waya. Tinovimba kuti iwe unonzwa zvakafanana mushure mekuverenga chinyorwa chedu nezve nzira yekuona iyo isina kwayakarerekera waya ine multimeter.. Paunenge uchibata nemagetsi, nguva dzose yeuka kutevera mitemo inodiwa yekuchengetedza.
Unogona kutarisa mamwe madhairekitori emultimeter pazasi;
- Maitiro ekushandisa multimeter kutarisa voltage yewaya mhenyu
- Nzira yekutsvaga waya ne multimeter
