Iyo musimboti wetambo yemagetsi inonyanya kuumbwa nemaconductor akawanda, ayo akakamurwa kuita imwechete musimboti, kaviri musimboti uye matatu musimboti.

Single-core cables anonyanya kushandiswa mune imwechete-phase AC uye DC maseketi, nepo matatu-core tambo achinyanya kushandiswa mutatu-chikamu AC.

circuits.Kune single-core cables, hukama pakati pepakati dhayamita netambo yekunze dhayamita iri nyore.Kazhinji,

waya yepakati dhayamita inenge 20% kusvika 30% yetambo yekunze dhayamita.Naizvozvo, tinogona kufungidzira dhayamita yepakati nekuyera

iyo dhayamita yekunze yetambo.

Kune matatu-yakakosha tambo, sezvo iyo-nhatu-chikamu chazvino ichigadzira magineti mumakondukita, pesvedzero yenzvimbo.

pakati pemaconductor uye insulation layer inoda kutariswa.Naizvozvo, kana uchiverenga dhayamita yekunze yetambo,

zvinhu zvakaita seye conductor cross-sectional area, nzvimbo iri pakati pemakondakita uye ukobvu hweiyo insulation layer inoda

kutariswa.Saka nzira yekuverenga dhayamita yekunze yetambo?Ngatitarisei pazasi.

▌01 Cable yekunze dhayamita nzira

Zvinhu zvinotevera zvinofanirwa kutariswa paunenge uchiverenga dhayamita rekunze retambo:

1. Conductor yekunze dhayamita: dhayamita yemuitisi mukati metambo;

2. Insulation layer thickness: hupamhi hwemukati wekudzivirira kwemukati wetambo;

3. Ukobvu hwemachira: ukobvu hwekunze kwetambo;

4. Nhamba yekodhi cores: nhamba yetambo yetambo mukati metambo.

Tichifunga nezvezvinhu zviri pamusoro, iyo inotevera fomula inogona kushandiswa kuverenga dhayamita rekunze retambo:

Outer dhayamita = kondakita dhayamita rekunze + 2 × insulation layer ukobvu + 2 × sheath ukobvu

Pakati pavo, iyo dhayamita yekunze ye conductor inogona kuwanikwa nekubvunza bhuku rekushandisa kana kuyera zvinoenderana ne

tsanangudzo dze conductor;kukora kwechidzitiro chekudzivirira uye kukora kwesheath kunogona kuwanikwa nekubvunza

zvinotsanangurwa netambo kana kuyera.

Izvo zvinofanirwa kucherechedzwa kuti formula iri pamusoro inoshanda kune imwechete-core tambo.Kana iri multi-core tambo, inoda kuverengerwa zvinoenderana

kune inotevera formula:

Outer dhayamita = (dhayamita rekunze re conductor + 2 × insulation layer ukobvu + 2 × sheath ukobvu) × nhamba yetambo cores + 10%

Paunenge uchiverenga iyo dhayamita yekunze yeyakawanda-yakakosha tambo, 10% kushivirira inoda kuwedzerwa kune mhedzisiro.

▌02 Kungwarira kwakabatana

1. Usati waverenga, iwe unofanirwa kunyatso simbisa iyo tambo yakatarwa, conductor cross-sectional nzvimbo uye rumwe ruzivo

chengetedza chokwadi chekuverenga;

2. Paunenge uchiverenga, zvinodikanwa kuti utarise mamiriro ekushandiswa kwetambo, senge pasi pevhu, pamusoro pevhu, pamusoro.

uye mamwe nharaunda, nekuti nharaunda dzekushandisa dzakasiyana dzinoda akasiyana sheath zvinhu kuti zvisarudzwe;

3. Paunenge uchiverenga, iwe unofanirwawo kufunga nezvekuisa nzira yetambo, senge yakagadziriswa kana inofambiswa, iyo inozokanganisa

saizi uye kusimba kwekusimba kwetambo;

4. Teerera kune kushivirira paunenge uchiverenga dhayamita rekunze retambo, uye sarudza kana kumwe kushivirira kuchida

kuwedzerwa kune chigumisiro chekuverenga zvichienderana nemamiriro chaiwo.

Muchidimbu, kuverenga kwekunze kwetambo yetambo kunoda kutarisisa kwakadzama kwezvinhu zvakawanda.Kana usiri

chokwadi nezvechiverengero nzira kana parameters, unofanira kubvunza nyanzvi kana kubvunza ruzivo rwakakodzera.
