Denmark 3Pin Plug kune C13 muswe tambo yemagetsi

Iwaya rudzii waya yakanaka

Chikamu chakasimba chemazuva ano chinowanzoreva tambo yemagetsi AC380 / 220V, zvakadai sezvigadziko, zvigadziro zvemwenje, air conditioning, heaters, midziyo yekicheni, nezvimwewo. kwete kutsanangura zvakanyanya.

Saka, sei kutonga kumira kana kudonha kwesimba rakasimba rekugadzira waya yemagetsi?

Imwe, inowanzoshandiswa pakushongedza kweimba kweiyo yakasimba BV waya inowanzoshandiswa mukugadzirisa imba.

Kune marudzi akawanda ewaya, anowanzo shandiswa waya chiratidzo ndeye BVBVR, BVVB, RVV, musiyano unotevera: Vaviri, waya mugadziri BV waya sei kuziva?

1. Kuzivikanwa kwehurefu Inogona kutaura, kunyanya mawaya emagetsi pamusika haana kukwana mamita 100, anogutsa tambo dzemagetsi dze 98 metres kumusoro, anga ari mugadziri wehana.Asi kana iwe uchida kugadzirisa ndiro nemutongi zvishomanana. kureba, kwete chete kunetsa zvikuru, asiwo regai chitoro anogona kuona uri duku chena.Saka, pane nzira kuverenga kureba waya pasina kupedza dhisiki?

Ehe, indasitiri yazvino yakaziva nzira yekuyera, iko kukanganisa kuri mukati memita 1:

Nzira yacho ndeiyi:

A: nhamba yewaya mundege yakatwasuka

B: nhamba yewaya mundege yakatwasuka

C Length: kureba kubva kune chero kunze kwe reel kusvika kure mukati memucheto wemukati reel

Chiverengo chekuverenga ndeichi: Nhamba yewaya mumamita = Nhamba yewaya A x Nhamba yewaya B x kureba C x 3.14

Semuenzaniso, conductor BV2.5, mushure mekuyera kwekutanga, nhamba yeA ndeye 12;Nhamba yeB: 16;Kureba kweC: 16.5 masentimita, kureva, 0.165 mamita, kureba kwetambo kunogona kuverengwa se: 12 × 16 × 0.165 × 3.14 = 99.47 mamita.

Iyi nzira inoshandawo kune 4 square uye 6 square waya.

2. Mutsara dhayamita kuzivikanwa

Tinowanzoti 2.5 square BV line, inowanzonzi single core wire kana copper plastic waya, inoreva waya yemhangura, kureva, nzvimbo yemhangura yeCOPPER wire BV2.5 line i 2.5 square millimeters.Zvadaro, maererano nemaitiro enharaunda yedenderedzwa, dhayamita yewaya yemhangura inofanira kunge inenge 1.78mm, inova chiyero chenyika.

Huwandu hwakadii?Shandisa vernier calipers:

Mukuwedzera, zvakakosha kuziva kuti pakuyera kubva kumativi ose ereel, kunyange kana tambo yetambo yakakura zvakakwana, hazvirevi hazvo kuti tambo yose yakakwana yakakwana.Nekuti zvakawanda zvezvigadzirwa zvisina kusimba, kubva pakutanga kwemamita matatu hapana dambudziko, asi mushure memamita matatu akatanga kutetepa, kusvika Z mushure memamita matatu kana zvakadaro, uye kudzorera kune yakajairika dhayamita, izvi imhaka yekuti mugadziri ari mukugadzira. yekudhirowa kwemhangura waya.Saka pakutenga waya, maoko mazhinji ekare achabvunza mukuru webasa: "Iyo waya inodhonzwa pakati?"Kana sabhuku achitya kuti kwete, panguva ino, kuve akangwarira.

3, chiziviso chemhangura

Mutengo mukuru wewaya ndeye simbi conductor, nepo GB yepurasitiki waya yemhangura inoshandisa mhangura isina oxygen semutyairi.Waya dzisiri dzenguva dzose dzichashandisa simbi dzine mhangura yakaderera semakondukita, sendarira, galvanized copper, copper-clad copper (ndarira yakafukidzwa nedungwe remhangura), kunyangwe copper-clad aluminium, copper-clad simbi, etc. inodzivirira zvakanyanya kupfuura mhangura, ichigadzira kupisa kwakawanda uye kukonzera tsaona.

Unoziva sei?

Kazhinji kutaura, iyo yakawanda yero ruvara, iyo shoma yemhangura yemukati.Brass ndeyeyero chaiyo, uye mhangura yakati tsvuku.Iwe unogona kushandisa pliers kucheka, tarisa chikamu, ona kana ruvara ruchienderana, zviri nyore kutonga kana iri mhangura yakaputirwa aluminium uye zvichingodaro.

4. Insulation identification

Kutanga tarisa kukora kwewaya sheath (insulator).Muyero wenyika 1.5-6 square wire isina oxygen copper inoda sheath ukobvu (insulation thickness) ye0.7mm.Kana yakanyanya kukora, kona inogona kukonzerwa nekushaikwa kwemukati wepakati dhayamita.;Uye wozotonga kunaka kweiyo insulator, iyo fake chigadzirwa, zviri nyore kupaza waya casing nekuidhonza neruoko.

5. Kuzivikanwa kwehuremu

Waya dzemhando yepamusoro dzinowanzova mukati mehuremu hwakatarwa.Semuenzaniso, uremu hweiyo inowanzo shandiswa BV1.5 mutsara ndeye 1.8-1.9kg pa100m;

Huremu hweBV2.5 mutsetse ndeye 3-3.1kg pa100m;

Huremu hweBV4.0 mutsetse ndeye 4.4-4.6kg pa100m.

Waya dzemhando dzakaipa hadzina kurema zvakakwana, kana kuti hadzina kureba, kana mhangura yewaya yanyanya kune imwe nyika.
