Denmark 3Pin Plug kupita ku chingwe chamagetsi cha C13

Waya wamtundu wanji ndi waya wabwino

Gawo lamphamvu lamakono nthawi zambiri limatanthawuza chingwe chamagetsi cha AC380 / 220V, monga zitsulo, zipangizo zounikira, mpweya, kutentha, zipangizo zakhitchini, ndi zina zotero. osafotokoza zambiri.

Kotero, momwe mungaweruzire choyimira kapena kugwa kwa opanga magetsi amphamvu?

Chimodzi, chomwe chimagwiritsidwa ntchito kwambiri kukongoletsa kunyumba kwa waya wamphamvu wa BV nthawi zambiri amagwiritsidwa ntchito pokongoletsa nyumba.

Pali mitundu yambiri ya mawaya, omwe amagwiritsidwa ntchito kawirikawiri chizindikiro cha waya ndi BVBVR, BVVB, RVV, kusiyana kuli motere: Awiri, waya wopanga BV waya momwe angadziwire?

1. Utali chizindikiritso Tinganene, kwenikweni mawaya onse magetsi pa msika ndi osakwanira 100 mamita, kukhutitsa mawaya magetsi 98 mamita pamwamba, anali Mlengi wa chikumbumtima.Koma ngati mukufuna kuthetsa mbale ndi wolamulira pang'ono pokha. kutalika, osati zovuta kwambiri, komanso lolani sitolo ikuwoneni ndinu woyera yaying'ono.Choncho, kodi pali njira yowerengera kutalika kwa waya popanda kusungunula diski?

Inde, makampani apano adazindikira njira yoyezera, cholakwikacho chili mkati mwa mita imodzi:

Njirayi ndi iyi:

A: chiwerengero cha mawaya mu ndege yopingasa

B: chiwerengero cha mawaya mu ndege yowongoka

C Utali: kutalika kuchokera kunja kulikonse kwa reel mpaka m'mphepete mwamkati mwa reel

Njira yowerengera ili motere: Chiwerengero cha mawaya mu mita = Chiwerengero cha mawaya A x Nambala ya mawaya B x kutalika C x 3.14

Mwachitsanzo, kondakitala BV2.5, mutatha kuyeza koyamba, chiwerengero cha A ndi 12; Chiwerengero cha B: 16; Kutalika kwa C: 16.5 masentimita, ndiko kuti, mamita 0,165, kutalika kwa waya kungawerengedwe ngati: 12 × 16 × 0.165 × 3.14 = 99.47 mamita.

Njirayi imagwiranso ntchito pa mawaya 4 ndi mawaya 6.

2. Chizindikiritso cha mainchesi a mzere

Nthawi zambiri timati 2.5 square BV line, yomwe imadziwika kuti waya imodzi yokha kapena waya wapulasitiki wamkuwa, imatanthawuza waya wamkuwa, ndiye kuti, gawo la mtanda wa COPPER waya BV2.5 ndi 2.5 millimeters. Kenako, malinga ndi dongosolo la dera la bwalo, m'mimba mwake wa waya wamkuwa ayenera kukhala pafupifupi 1.78mm, womwe ndi muyezo wadziko lonse.

kuchuluka kwake? Gwiritsani ntchito vernier calipers:

Kuonjezera apo, ndikofunika kuzindikira kuti poyezera kuchokera ku malekezero onse a reel, ngakhale kuti waya wa waya ndi waukulu mokwanira, sizikutanthauza kuti waya wonsewo ndi wokwanira. Chifukwa zambiri shoddy mankhwala, kuyambira chiyambi cha mamita atatu palibe vuto, koma pambuyo mamita atatu anayamba woonda, kuti Z pambuyo mamita atatu kapena apo, ndi kubwezeretsa m'mimba mwake yachibadwa, ndi chifukwa Mlengi m'kati kupanga. ya copper wire kujambula processing. Choncho pogula waya, manja ambiri akale adzafunsa abwana kuti: "Kodi waya amakokedwa pakati?" Ngati bwana akuwopa kunena kuti ayi, pa nthawi ino, kukhala tcheru kwambiri.

3, chizindikiritso cha mkuwa

Mtengo waukulu wa waya ndi woyendetsa zitsulo, pomwe waya wamkuwa wa pulasitiki wa GB umagwiritsa ntchito mkuwa wopanda okosijeni ngati woyendetsa. Mawaya osakhazikika adzagwiritsa ntchito zitsulo zokhala ndi mkuwa wochepa ngati ma conductor, monga mkuwa, mkuwa, malata, mkuwa wovala mkuwa (mkuwa wokutidwa ndi wosanjikiza wamkuwa), ngakhale aluminiyamu yokhala ndi mkuwa, zitsulo zovala zamkuwa, ndi zina. kupirira kwambiri kuposa mkuwa, kutulutsa kutentha kwambiri ndikuyambitsa ngozi.

Mukudziwa bwanji?

Nthawi zambiri, mtundu wachikasu umakhala wochepa kwambiri. Mkuwa ndi wachikasu koyera, ndipo mkuwa ndi wofiira pang'ono. Mutha kugwiritsa ntchito pliers kuti mudule, yang'anani gawolo, muwone ngati mtunduwo umagwirizana, osachepera ndizosavuta kuweruza ngati ndi aluminiyamu yokulungidwa yamkuwa ndi zina zotero.

4. chizindikiritso cha kutchinjiriza

Choyamba yang'anani makulidwe a waya m'chimake (insulator). The dziko muyezo 1.5-6 lalikulu waya popanda mpweya mkuwa amafuna m'chimake makulidwe (kuteteza makulidwe) wa 0,7mm. Ngati ndi yokhuthala kwambiri, ngodya imatha chifukwa cha kusowa kwapakati pakatikati. ; Ndiyeno kuweruza ubwino wa insulator, mankhwala abodza, n'zosavuta kung'amba casing waya pochikoka ndi dzanja.

5. Kuzindikiritsa kulemera

Mawaya abwino nthawi zambiri amakhala mkati mwa kuchuluka kwake komwe kumatchulidwa. Mwachitsanzo, kulemera kwa mzere wogwiritsidwa ntchito kwambiri wa BV1.5 ndi 1.8-1.9kg pa 100m;

Kulemera kwa mzere wa BV2.5 ndi 3-3.1kg pa 100m;

Kulemera kwa mzere wa BV4.0 ndi 4.4-4.6kg pa 100m.

Mawaya abwino sali olemetsa mokwanira, kapena osatalika, kapena phata la waya ndi lachilendo kwambiri.
