Kuchengeta yakafanira waya color coding system inovimbisa yakachengeteka uye nyore wiring. Dzimwe nguva izvi zvinogona kudzivirira njodzi inouraya. Kana kuti dzimwe nguva inogona kukubatsira kuchengetedza iwe panguva yeprojekti. Ndicho chikonzero nhasi tiri kusarudza musoro wakapfava une mhinduro mbiri. Waya nhema iri positive kana negative?

Kazhinji, polarity yewaya dema zvinoenderana nerudzi rwedunhu. Kana uri kushandisa DC circuit, waya tsvuku ndeye positive current uye dema wire ndeye negative current. Waya yepasi inofanira kuve yakachena kana grey kana dunhu rakadzikwa. Mudunhu re AC, waya nhema yakanaka uye waya chena haina kunaka. Waya yepasi yakasvibira.

mhinduro yakananga

Kana iwe uchiri kusava nechokwadi nezve polarity yewaya nhema, heino tsananguro iri nyore. Mumaseketi eDC, waya nhema ndiyo waya isina kunaka. Mumaseketi eAC, waya nhema ndiyo waya yakanaka. Saka, zvakakosha kuti uone hurongwa hwedunhu usati waona polarity yewaya nhema. Zvisinei, vanhu vakawanda vanovhiringidzika nokukurumidza. Kuita izvi kunogona kukonzera kuvhunduka kwemagetsi kana kukanganisa midziyo yemagetsi.

Mhando dzakasiyana dzewaya mavara makodhi

Zvichienderana nerudzi rwedunhu, unogona kusangana akati wandei akasiyana waya mavara macode. Kuziva aya macode eruvara rwewaya kunobatsira iwe munzira dzakawanda. Chinonyanya kukosha, ichaita kuti kuchengeteka. Pano ndinotarisira kukurukura DC uye AC waya mavara macode.

DC Power Wire Color Codes

Yakananga ikozvino, inozivikanwawo seyakananga ikozvino, inofamba mumutsara wakatwasuka. Nekudaro, simba reDC harigone kufambiswa pamusoro pemadaro marefu senge AC simba. Mabhatiri, masero emafuta uye masero ezuva ndiwo anonyanya kuzivikanwa emagetsi eDC. Neimwe nzira, unogona kushandisa rectifier kushandura AC kuita DC.

Heano mawaya mavara macode eDC simba.

Red wire for positive current.

Black wire ye negative current.

Kana iyo DC yedunhu iine waya yepasi, inofanirwa kuve chena kana grey.

Ramba uchifunga: Kazhinji, maseketi eDC ane waya nhatu. Asi dzimwe nguva unenge uine waya mbiri chete. Waya inoshaikwa ivhu.

AC Power Wire Color Codes

Alternating current, inozivikanwawo sealternating current, inowanzoshandiswa mudzimba nemabhizinesi. Simba re AC rinogona kuchinja nzira nguva nenguva. Tinogona kutaura nezve alternating current se sine wave. Nekuda kweiyo waveform, AC simba rinogona kufamba kure kupfuura DC simba.

Pamagetsi akasiyana, mhando yesimba re AC ichave yakasiyana. Semuenzaniso, mhando dzemagetsi dzinowanzozivikanwa ndeye 120V, 208V uye 240V. Izvi zvakasiyana-siyana zvinouya nezvikamu zvakawanda. Mune ino post, isu tichataura nezve matatu-chikamu simba.

Matatu-chikamu simba

Rudzi urwu rwemagetsi eAC ane waya nhatu mhenyu, waya imwe isina kwayakarerekera, uye imwe pasi waya. Nekuti simba rinobva kumawaya matatu akasiyana, iyi 1-phase system inogona kuburitsa simba rakawanda nekuita zvakanaka. (XNUMX)

Heano mavara ewaya macode emagetsi eAC.

Iyo phase 1 waya inofanira kunge yakasviba, uye ndiyo nhema inopisa waya yatambotaura muchinyorwa.

Phase 2 waya inofanira kuva tsvuku.

Phase 3 waya inofanira kuva yebhuruu.

Waya chena iwaya isina kwayakarerekera.

Waya yepasi inofanira kunge yakasvibira kana yegirini ine mitsetse yeyero.

Ramba uchifunga: Waya nhema, dzvuku uye bhuruu iwaya dzinopisa mukubatana kwezvikamu zvitatu. Zvisinei, waya ina chete inogona kuwanikwa mune imwe-chikamu chekubatanidza; dzvuku, dema, chena uye girini.

Summing up

Zvinoenderana neNational Electrical Code (NEC), iwo pamusoro apa waya mavara makodhi ndiwo eUS wiring zviyero. Saka, tevera nhungamiro idzi pese paunenge uchiita chirongwa chewaya. Zvichakuchengetedza iwe neimba yako zvakachengeteka. (2)
