Mugwagwa Wakanyarara: Nei Kugona Kwekutakura Cable Pari Zvino Kuri Mushonga Wenyika Yanhasi

Mukati mehunhu hwedu hwakazara nemagetsi, tambo yemagetsi inozvininipisa igamba risingaimbwe. Tinovaona vachisvetuka-svetuka seri kwemadziro, vakasungirirwa mumatireyi emaindasitiri, uye pasi pevhu, vachinyanya kufuratira basa ravo rakakosha. Asi, pakati pehurongwa hwese hwemagetsi hwakachengeteka, hunoshanda, uye hwakavimbika pane mubvunzo uri nyore unonyengera: Ingani simba remagetsi iri rinogona kutakura zvakachengeteka? Mhinduro, inotsanangurwa neKukwanisa Kutakura Kwemazuva Ano Kwezita, ikuverenga kwakaomarara kune zvakunoreva zvikuru pakuchengetedzeka, kushanduka kwesimba, uye kushanda zvakanaka kwehupfumi.

Iyi parameter huru, inowanzopfupikiswa seAmpacity, haisi nhamba isingachinji yakadhindwa papepa rema spec. Inhamba inoshanduka, kubvumirana kwakanyatsojeka pakati pefizikisi, sainzi yezvinhu, uye chokwadi chezvakatipoteredza. Kunzwisisa izvi hakusi kungonetsa mainjiniya chete; zvakakosha kune wese munhu kubva kuvagadziri vemitemo vari kuronga kuvandudza grid yenyika kusvika kune varidzi vedzimba vari kuisa charger yemotokari yemagetsi.

Kutsanangura Mutsetse weHupenyu: Chii chaizvo chinonzi Ampacity?

Kugona kwemagetsi emagetsi emhando yepamusoro (nominated current) kwetambo ndiyo simba remagetsi rinoenderera mberi raunogona kutakura mumamiriro ezvinhu akatarwa pasina tembiricha yaro yakagadzikana kupfuura muganho wakatarwa. Muganho uyu wekupisa wakakosha nekuti kuipfuura kunokurumidza kuparara kwekudzivirira kwetambo, zvichikonzera kutadza kushanda zvakanaka, ma "short circuits", uye, muzviitiko zvakanyanya, moto.

“Funga nezvetambo semugwagwa wakamanikana,” anotsanangura kudaro Dr. Alisha Sharma, purofesa weinjiniya yemagetsi paInstitute of Technology. “Maerekitironi ndiwo mota. Mwenje wemagetsi ndiwo huwandu hwemotokari dzinopfuura poindi imwe pasekondi. Kana ‘mota’ dzakawanda dzichiedza kushandisa mugwagwa, kukweshana—kana kuramba magetsi—kunounza kupisa. Kana kupisa kukasakwanisa kupera nekukurumidza, ‘mugwagwa’ pachawo, chinhu chinodzivirira kupisa, chinotanga kunyunguduka. Kuwanda kwemagetsi ndiyo nzira inodzivirira dambudziko iri.”

Mbiru Ina Dzekukura: Kuenzana Kwakanaka

Kuyera kwemagetsi kwetambo hakubvi pamhangura kana aruminiyamu. Kunotsamira pakuenzanisa zvinhu zvina zvakakosha:

1. Zvinhu zveConductor uye Saizi: Chinhu Chikuru cheNhau

Chinhu chinonyanya kunzwisisika imuchina wacho. Mhangura, ine simba rekufambisa zvinhu zvakanyanya, ine simba rekuwedzera simba kupfuura aruminiyamu panzvimbo imwe chete. Ndokusaka mashandisirwo emagetsi anowanzo shandiswa nemhangura.

Chinonyanya kukosha ihukuru, hunoyerwa mu square millimeters (mm²) kana AWG (American Wire Gauge). Kondakita yakakora haina simba remagetsi rakawanda, rakafanana nepombi yakafara inobvumira mvura yakawanda kuyerera pasina kumanikidzwa kwakawanda. Semuenzaniso, PVC-insulated yakajairwa Waya yemhangura inogona kuverengerwa maAmps angangoita gumi nematanhatu pa1.5mm², asi izvi zvinogona kukwira kusvika pamaAmps anopfuura zana patambo ye25mm².

2. Zvinhu zvekudzivirira: Thermal Guardian

Rudzi rwekudzivirira kupisa ndiro chinhu chikuru chinoratidza tembiricha yepamusoro inobvumirwa. Zvinhu zvakasiyana zvine kutsungirira kwakasiyana kwekupisa.

PVC (Polyvinyl Chloride):Yakajairika uye inodhura zvishoma, asi tembiricha yekushanda yakaderera (kazhinji 70°C). Izvi zvinoderedza kugona kwayo kushanda.

XLPE (Polyethylene Yakabatana Nemitsetse):Chinhu chakanaka kwazvo, kuburikidza nemaitiro emakemikari, chinogona kutsungirira tembiricha yakakwira (kazhinji 90°C). Izvi zvinobvumira tambo ine insulation yeXLPE kutakura simba rakawanda kupfuura ine insulation yePVC yehukuru hwakafanana.

Rabha (semuenzaniso, EPR):Inopa kuchinjika kwakanaka uye inodzivirira kupisa, inowanzoshandiswa munzvimbo dzinoda kushanda nesimba dzakadai sekuchera migodhi kana zviitiko zvepamoyo.

Kudzivirira Zvicherwa (MI): Inogona kutsungirira tembiricha dzakanyanya kudarika 250°C, inoshandiswa mukuchengetedza moto zvakanyanya uye mukushandiswa kwekupisa kwakanyanya.

3. Nzira yekuisa: Chinhu Chinokosha Chekutonhodza

Maitiro uye kupi kwetambo inoiswa kunokanganisa zvakanyanya kugona kwayo kuderedza kupisa. Ichi ndicho chinhu chinowanzo furatirwa munzvimbo dzisiri dzehunyanzvi.

Yakachekwa Yakananga Pamusoro Kana Kuvigwa Zvakananga Muvhu:Izvi ndizvo zvimwe zvezvinhu zvakanakisisa zvekutonhodza. Mhepo kana ivhu zvinogona kutenderera zvichibvisa kupisa, zvichikonzera kuwanda kwakanyanya.

Yakavharirwa muConduit kana Trunking:Iyi inzvimbo ine muganho mukuru. Tambo dzinoungana pamwe chete munzvimbo yakamanikana dzinobata kupisa, zvichikonzera kukwira kwekupisa. Mitemo yenyika yekubatanidza waya, seNEC muUS kana IEC 60364 pasi rose, inoda kuti pave nemutemo unokoshazvinhu zvinokanganisaWaya inogona kutakura maAmps makumi mana mumhepo inogona kuderedzwa kuita maAmps makumi maviri nemasere chete kana yakabatanidzwa nemamwe maviri mugomba.

Yakavigwa mumigero yemvura: Kudzivirira kupisa kwevhu rakatenderedza kunoita basa guru. Ivhu rakaoma, rine jecha hariiti kuti kupisa kupfuure kana tichienzanisa nevhu rakanyorova, zvichiita kuti mvura isapfuure zvakanaka.Tembiricha yeAmbient: Nheyo Yezvakatipoteredza

4. Chiyero chewaya chinobva patembiricha yakajairika yemhepo, kazhinji 30°C mumhepo kana 20°C muvhu. Kana waya yakaiswa muboiler room kana padenga rakapiswa nezuva uko tembiricha yemhepo iri 50°C, kugona kwayo kutonhora kunokanganiswa zvakanyanya. Kukura kwayo kunofanira kuderedzwa kudzivirira huwandukukwira kwemhepo netembiricha kubva pakupfuura muganho wekudzivirira kupisa.

Kuenzanisa: Kuisa Dzidziso Mukushanda

Kubatana kwezvinhu izvi kunonyatsoratidzwa nemienzaniso. Funga nezve conductor yemhangura ye 16 mm²:

PVC Yakaputirwa, Yakachekwa Yakananga:Kukura kwayo kunogona kunge kuri paMaAmp makumi masere.

XLPE Yakaputirwa, Yakachekwa Yakananga:Nekuda kwekupisa kwayo kwakanyanya, kondakita imwe cheteyo yaigona kutakuraMaampisi zana.

XLPE Insulated, muConduit ine dzimwe tambo mbiri:Nekudzvanywa kwemapoka, kugona kwayo kuchengetedzeka kunogona kudzikira kusvikaMaAmp makumi manomwe neshanu.

Waya imwecheteyo pakupisa kwe45°C:Kumwe kutsoropodza kunogona kusundira nhamba yekupedzisira pasi kusvikaMaAmp makumi matanhatu nemashanu.

Izvi zvinoratidza pachena kuti nei kungosarudza tambo zvichienderana nehukuru hwemuchina wayo kuri mutambo une njodzi.
