Sarudza waya maererano nehuwandu hunobvumirwa hwehuwandu hwekutakura huripo hwetambo

Iyo wire cross chikamu chemukati wiring inofanira kusarudzwa zvichienderana neinobvumirwa ikozvino kutakura kugona kwewaya, inobvumirwa voltage kurasikirwa kukosha kwemutsara, uye mechanical simba rewaya.Kazhinji, waya inotakura nzvimbo inosarudzwa maererano neinobvumirwa ikozvino kutakura simba, uye ipapo kuongororwa kunoitwa maererano nemamwe mamiriro.Kana chikamu chemuchinjikwa chisingaenderane nezvinodiwa zveimwe mamiriro ekugadzirisa, kondakita anofanira kusarudzwa maererano nehuwandu hunobvumirwa chikamu chemuchinjikwa chisingakwanisi kusangana nemamiriro acho.

Wire inotenderwa ampacity: Iyo inobvumidzwa ampacity yewaya inonziwo yakachengeteka ampacity kana yakachengeteka ikozvino kukosha kwewaya.Iyo yakanyanya kubvumidzwa tembiricha yekushanda yewaya yakajairwa i65°C.Kana tembiricha yakapfuura tembiricha iyi, iyo yekuvharisa layer yewaya ichakurumidza kuchembera, yakashata uye yakakuvadzwa, uye inogona kutokonzera moto.Iyo inonzi inobvumirwa ikozvino kutakura simba rewaya ndiyo yakanyanya kukosha ikozvino inogona kupfuudzwa kwenguva yakareba kana tembiricha yekushanda isingapfuuri 65 ° C.

Sezvo tembiricha yekushanda yewaya isingabatanidzi chete neyazvino ichipfuura netambo, asiwo ine chekuita nekupisa kwekupisa mamiriro ewaya uye ambient tembiricha, iyo inotenderwa inotakura simba retambo haisi iyo yakatarwa kukosha.Kana waya imwechete inotora nzira dzakasiyana dzekuisa (nzira dzakasiyana dzekuisa, mamiriro ayo ekupisa kupisa anosiyanawo) kana pane akasiyana tembiricha ambient, inobvumirwa ikozvino kutakura inosiyanawo.Tarisa kune yemagetsi tekinoroji bhuku rezvinotenderwa kutakura-kutakura simba rewaya nenzira dzakasiyana dzekuisa.

Ikozvino yemutsetse wemutsetse unogona kuverengerwa neinotevera formula:

Single-phase pure resistance circuit: I=P/U

Single-phase circuit ine inductance: I=P/Ucosφ

Matatu-chikamu chakachena kuramba dunhu: I=P/√3UL

Matatu-chikamu chedunhu chine inductance: I=P/√3ULcosφ

Zvinorehwa nemaparameter ari pamusoro apa mafomula ndeizvi:

P: isimba remutoro, mu watts (W);

UL: ndiyo magetsi emagetsi emagetsi matatu, mu volts (V);

cosφ: ndiro simba chinhu.

Paunenge uchisarudza maererano neinobvumirwa ikozvino kutakura kukwanisa kwetambo, nheyo huru ndeyokuti inobvumirwa ikozvino kutakura simba haisi pasi peiyo yakaverengwa ikozvino yemutsara wakagadzirwa.
