Nzira yekuziva sei waya inopisa pasina multimeter (4 nzira)

Zviri mukati

Nzira 1: shandisa detector yepedyo
Nzira 2: Shandisa tester screwdriver
Method 3: shandisa girobhu remwenje semuyedzo
- Nzira yekugadzira girobhu remwenje
- Kushandisa girobhu remwenje kuziva waya mhenyu
Method 4: Kushandisa Color Codes

Muchikamu chino, ini ndichakuratidza nzira yekuziva waya inopisa kana mhenyu pasina kushandisa multimeter.

A multimeter inokubvumira kuti utarise polarity yewaya; zvisinei, kana iwe usina, kune dzimwe nzira dzokuita zvakafanana. Semugadziri wemagetsi anovimbwa, ndakadzidza matipi mashoma uye matipi mumakore apfuura ekunongedza tambo mhenyu pasina kushandisa multimeter, yandinogona kukudzidzisa. Dzimwe nzira dzinogona kukubatsira nekuti multimeter inogona kudhura zvakanyanya pabasa rako renguva imwe chete.

Kazhinji, kana iwe usina multimeter, unogona kushandisa:

Voltage detector
Bata screwdriver
Batanidza girobhu remwenje kune waya
Shandisa kodhi yemuvara wakajairika

Ini ndichavhara imwe neimwe zvakadzama pazasi.

Nzira 1: shandisa detector yepedyo

Ndinonzwisisa kuti danho iri rinogona kunge risingawaniki kana iwe usingakwanisi kuwana chero ipi zvayo yezvigadzirwa zvemagetsi, pane izvo zvandinoda kuti uende kune zvitatu zvinotevera.

Tevedza aya matanho ari nyore kuona kana waya iri kupisa uchishandisa isiri-contact voltage detector.

vanotsika 1. Chengeta detector yepedyo pedyo nechinhu kana bvunzo.

vanotsika 2. Chiratidzo chiri pa detector chichavhenekera.

vanotsika 3. Iyo isiri-contact voltage detector icharidza kana paine voltage muchinhu kana waya.

vanotsika 4. Iwe uri kutarisa kuti ikozvino inoyerera kuburikidza newaya yakakosha.

Mazano: Usabate voltage detector nema probes, waya kana chero chimwe chikamu chemuyedzo panguva yebvunzo. Izvi zvinogona kukanganisa muyedzi uye kuita kuti isachengeteke kushandisa.

Mazhinji ma detectors anoshanda nekuita alternating magnetic field muchinhu chiri kuedzwa. Kana chinhu chacho chikasimbiswa, iyo induced magnetic field ichaita kuti magetsi afambe. Iyo detector yedunhu ichabva yaona ikozvino uye beep.

Nekudaro, ita shuwa kuti isiri-yekubata voltage detector iri kushanda isati yashandiswa. Izvi zvakakosha nekuti mhedzisiro inorasisa inogona kukonzera kukuvara kwakakura uye tsaona.

Nzira 2: Shandisa tester screwdriver

Imwe nzira yekuona kana waya ichipisa kana kurarama ndeye kushandisa tester screwdriver.

ORDER

Danho 1: fumura waya

Unogona kuvhura chivharo kana kubvisa chero chinhu chinoita kuti waya dzisasvike.

Zvichida iwe unoda kutarisa mawaya kuseri kwekuchinja; mune iyi kesi, sunungura chivharo chekuchinja kuti uwane waya waunoda kutarisa polarity.

Danho rechipiri: Tsvaga nzvimbo yakafumurwa pawaya

Nekuti waya zhinji dzakaiswa insulated, iwe unoda yakakwana uye isina nzvimbo yekubata iyo tester's screwdriver.

Kana iwe usingakwanise kuwana nzvimbo isina chinhu pawaya kwaunogona kuisa screwdriver ye tester, ini ndinokurudzira kubvisa waya. Asi chekutanga, iwe unofanirwa kudzima simba kune mudziyo wauri kushanda nawo pane switch panel. Usakurura waya mhenyu usina ruzivo rwakakwana. Unogona kubatwa nemagetsi.

Ita zvinotevera:

Tora waya stripper kana insulated pliers.
Dhonza waya dzaunoda kutarisa polarity
Isa inenge hafu yeinji yewaya mumashaya ewaya stripper kana pliers uye cheka insulation.
Iye zvino unogona kudzorera simba uye kuenderera mberi nemuedzo.

Danho rechitatu: Bata screwdriver ye tester kune waya dzisina chinhu.

Usati waenderera nekuyedzwa chaiko, ita shuwa kuti tester's screwdriver yakavharirwa zvakakwana kudzivirira tsaona.

Mushure meizvozvo, bata iyo insulated chikamu uye kubata iyo yakafumurwa kana yakabviswa waya. Ita shuwa kuti screwdriver ye tester inobata zvakanaka newaya.

Mukufanana, tarisa neon girobhu pascrewdriver, kana ukabata waya inopisa (ine screwdriver tester), iyo neon girobhu ichavhenekera. Kana iyo waya isina simba (pasi kana kusarerekera), iyo neon mwenje haibatike. (1)

Cherechedza: A defective tester screwdriver inogona kupa mhedzisiro isiriyo. Saka, ita shuwa kuti screwdriver yako iri kushanda. Zvikasadaro, unogona kunge uine pfupi dunhu.

Method 3: shandisa girobhu remwenje semuyedzo

Chekutanga, unofanirwa kuita kuti detector iyi ive nyore kushandisa. Unogona kuishandisa kuyedza waya inopisa.

Nzira yekugadzira girobhu remwenje

vanotsika 1. Ndapota cherechedza kuti girobhu remwenje rinofanira kubatanidzwa kune imwe mugumo wewaya. Saka, girobhu remwenje rinofanira kuva nemutsipa wakabatana newaya.

vanotsika 2. Batanidza imwe magumo ewaya kune plug kuti iiswe musocket.

Cherechedza: kwete dambudziko kana iwe ukabatanidza dema, tsvuku kana chero imwe waya kune girobhu; mwenje we tester unofanirwa kubata waya inopisa uye kuvhenekera - iyi ndiyo nzira yaunoona nayo waya inopisa.

Kushandisa girobhu remwenje kuziva waya mhenyu

vanotsika 1. Sarudza pasi - girini kana yero.

vanotsika 2. Tora tester uye ubatanidze imwe mugumo kune yekutanga tambo uye imwe kune yepasi waya. Kana chiedza chikauya, iwaya inopisa (tambo yekutanga). Kana zvisina kudaro, inogona kunge iri waya isina kwayakarerekera.

vanotsika 3. Tarisa imwe waya uye tarisa maitiro egirobhu.

vanotsika 4. Cherechedza waya mhenyu - iyo yakabatidza girobhu. Iyi ndiyo live wire yako.

Method 4: Kushandisa Color Codes

Zvichida iyi ndiyo nzira iri nyore yekunongedza tambo mhenyu kana inopisa mumudziyo wemagetsi kana tambo dzetambo; zvisinei, hazvisi zvese zvemagetsi zvine macode ewaya akafanana. Mukuwedzera, makodhi ewaya anosiyana nenyika nenzvimbo. Izvi zvinotevera chiyero chemavara ekugara kune waya dzemagetsi.

Muzvigadziriso zvemwenje zvemba zvakawanda, waya kodhi yakaita seiyi (US National Electrical Code)

waya nhema - iwaya dzine simba kana simba.
Waya dzakasvibira kana dzisina chinhu - sarudza waya dzepasi uye zvinongedzo.
waya dzeyero - zvakare inomiririra kubatana kwepasi
waya chena - itambo dzisina kwazvakarerekera.

Iyi chiyero chemavara inotangwa neNational Electrical Code uye inochengetwa neNational Fire Protection Association. (2)

Nekudaro, nekuda kwekusiyana kwezviyero zvemavara mune mamwe matunhu, haugone kuvimba zvachose nemakodhi emavara kuti uone waya mhenyu. Zvakare, usabate waya kusvika waziva kuti ndedzipi. Nenzira iyi, iwe unoderedza mukana wetsaona.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.
