Ingabe kuvamile ukuthi ikheyiji yesiteshi sokushaja kanye nekhebula lokushaja lishise ngesikhathi sokushaja, noma ingabe kuyingozi yokuphepha?

Njengoba ukwanda kokuthandwa kwezimoto ezintsha zamandla kuyanda,ishaja ye-ev yasekhayafuthiisiteshi sokushaja somphakathiseziyimishini esiyisebenzisa nsuku zonke. Abanikazi bezimoto abaningi babhekana nale nkinga lapho beshaja: “Isibhamu sokushaja sizwakala sishisa uma usithinta, kanti nebhokisi lesiteshi sokushaja nalo liyafudumala noma lishise. Ingabe lokhu kuvamile?"Lesi sihloko sizohlinzeka ngokuhlaziywa kobungcweti nokuphelele kwalolu daba.

I. Isiphetho: Ukushisa ngokweqile ≠ Ingozi, kodwa Ukushisa ngokweqile kuyingozi efihliwe

Kungakhathaliseki ukuthiUkushaja okusheshayo kwe-DC or Ukushaja okuhamba kancane kwe-AC, izintambo nezixhumi zizokhiqiza ukushisa okumelana nokushisa ngaphansi kwamandla aphezulu. Njengamashaja efoni nama-adaptha kagesi e-laptop, ukukhiqiza ukushisa kuyinto ebonakalayo, hhayi ukungasebenzi kahle.

Kodwa-ke, uma ukwenyuka kwezinga lokushisa kudlula ibanga elifanele, kubonisa inkinga engaba khona: njengokuntuleka kwendawo yethusi enganele ekhebulani, amajoyinti angasebenzi kahle okusoda, noma umlomo wokushaja ogugayo. Lezi zici zingabangela ukwanda okusheshayo kokushisa kwendawo, okungase kuholele ekushiseni, ekuqhekekeni, noma ngisho nasekushiseni.

II. Kungani amadivayisi okushaja ekhiqiza ukushisa?

Kungakhathaliseki ukuthiIsiteshi sokushaja se-ACnomaIsiteshi sokushaja okusheshayo se-DC, bobabili badinga ukuphatha ugesi omkhulu oqhubekayo ngesikhathi sokusebenza. Ama-conductor anokumelana, futhi ukushisa kukhiqizwa lapho ugesi ugeleza kuwo, njengoba kuboniswe kufomula: P = I² × R

Uma amandla okushaja efika ku-32A (Isiteshi sokushaja ekhaya esingu-7kW) noma ngisho no-200A~500A (Inqwaba yokushaja okusheshayo ye-DC), ngisho nokumelana okuphansi kakhulu kungadala ukushisa okukhulu. Ngakho-ke, ukukhiqizwa kokushisa okumaphakathi kuyinto evamile ngokomzimba futhi akuweli ngaphansi kwesigaba sokungasebenzi kahle.

Imithombo evamile yokushisa ihlanganisa:

1. Ukumelana nokushisa kwezintambo zokushaja ngokwazo
2. Ukwehla kwe-voltage yokuxhumana ekhanda lokushaja
3. Ukushabalaliswa kokushisa okuvela ezingxenyeni zamandla zangaphakathi
4. Ukushisa okwengeziwe okuvela ekushiseni okuzungezile kanye nokukhanya kwelanga

Ngakho-ke, kuvamile ukuthi abasebenzisi bazizwe “befudumele” noma “beshisa kancane” ngenkathi beshaja.

III. Yini ebangela ukwenyuka kwezinga lokushisa okuvamile?

Izindinganiso zemboni (njenge-GB/T 20234, GB/T 18487, QC/T 29106) zinezidingo ezithile zokwenyuka kwezinga lokushisaimishini yokushajaNgokuvamile:

1. Ububanzi Obujwayelekile
Izinga lokushisa elingaphezulu 40℃～55℃: Ukwenyuka kwezinga lokushisa elijwayelekile, kuphephile ukulisebenzisa.

55℃～70℃: Kuphezulu kancane kodwa kusengaphakathi kwemingcele eyamukelekayo ezimweni eziningi, ikakhulukazi ekushajeni kwe-DC enamandla aphezulu ehlobo.

2. Ububanzi obudinga ukuqaphela

＞70℃: Uma isondela noma idlula izinga lokushisa elivunyelwe yizinga elijwayelekile, ukushaja kumele kumiswe bese idivayisi ihlolwa.

Okulandelayo kubhekwa njengezehlakalo ezingavamile:

1. Ukuthambisa irabha noma ipulasitiki
2. Iphunga elivuthayo
3. Ukushintsha kombala kwamatheminali ensimbi ekhanda lokushaja
4. Izindawo ezisendaweni esixhumini ziba zishisa kakhulu uma zithintwa noma zingathintwa.

Lezi zenzakalo zivame ukuhlobana ngqo "nokumelana okungavamile kokuxhumana" noma "ukungacaciswa kahle kwentambo" futhi zidinga uphenyo olusheshayo.

IV. Yiziphi izinto ezingabangela ukushisa ngokweqile?

1. Indawo enganele yezintambo zethusi ezinqamulelanayo ezintanjeni:Eminye imikhiqizo esezingeni eliphansi isebenzisa izintambo “ezibhalwe ngamanga” ezinezindawo ezincane ezinqamula izintambo zethusi, okuholela ekumelaneni okuphezulu kanye nokwenyuka kwezinga lokushisa.

2. Ukwanda kwe-impedance kuma-plug, ama-terminal, nakwezinye izindawo zokuxhumana:Ukuguguleka nokuklebhuka ngenxa yokuxhuma nokukhipha i-plug, ukukhubazeka kwe-terminal, kanye nekhwalithi ephansi yokuxhuma konke kungandisa ukumelana kokuthintana, okubangela izindawo ezishisayo. "Ukushisa kwesixhumi okudlula okwekhebula uqobo" kuyisibonakaliso esivame kakhulu.

3. Umklamo ongemuhle wokushabalalisa ukushisa kwezingxenye zamandla angaphakathi:Isibonelo, ukushabalaliswa kokushisa okwanele kuma-relay, ama-contactor, kanye namamojula e-DC/DC kuzobonakala njengokushisa okuphezulu ngaphakathi kwe-casing.

4. Umthelela omkhulu wezinto zemvelo:Ukushaja ngaphandle ehlobo, amazinga okushisa aphezulu emhlabathini, kanye nokukhanya kwelanga okuqondile konke kuzosiza ekukhuphukeni kwezinga lokushisa okucatshangelwayo.

Lezi zici zinqumaumehluko wangempela wekhwalithi yezinqwaba zokushaja, ikakhulukazi ukuthembeka kwamakhono enkampani e-R&D, ukukhethwa kwezinto ezibonakalayo, kanye nezinqubo zokukhiqiza.

V. Unganquma kanjani ukuthi kukhona yini izingozi zokuphepha?

Abasebenzisi bangahlola isimo ngokushesha besebenzisa izindlela ezilandelayo:

Izenzakalo ezijwayelekile:

• Isibhamu sokushaja kanye nebhokisi kuyashisa uma kuthintwa.
• Akukho phunga noma ukuguquka.
• Izinga lokushisa lishintsha kakhulu ngokwanda kwezinga lokushisa elizungezile.

Izehlakalo ezingavamile:

• Ezinye izindawo zishisa kakhulu uma uzithinta, ngisho noma ungathinteki.
• Ikhanda lesibhamu sokushaja lishisa kakhulu kunekhebula uqobo.
• Kuhambisana nephunga elivuthayo, umsindo, noma ukuphazamiseka kokushaja ngezikhathi ezithile.
• Ikhanda lesibhamu sokushaja liyathambisa noma lishintsha umbala.

Uma kwenzeka noma yikuphi ukungahambi kahle, yeka ukusebenzisa idivayisi ngokushesha bese uxhumana nesevisi yangemva kokuthengisa noma ucele ukuthi ishintshwe.

VI. Ungayikhetha Kanjani Isiteshi Sokushaja?

Iziteshi zokushaja izimoto zikagesikuhilela izilinganiso eziningi zobuchwepheshe, kufaka phakathi amandla aphezulu kagesi, ukuphepha kukagesi, ukufakelwa kukagesi, kanye nokuphathwa kwezinga lokushisa, okubeka izidingo eziphezulu kakhulu ocwaningweni nasekuthuthukisweni nasekukhiqizweni. Abakhiqizi begama lomkhiqizo banezinzuzo ezibalulekile kulezi zindawo ezilandelayo: imininingwane enembile yekhebula (akukho okuqukethwe kwethusi okukhangiswa ngamanga), amakhanda okushaja anokwethenjelwa okuphezulu kanye nezinqubo zokubopha isikhathi eside, ukunyuka kwezinga lokushisa okuqinile, ukuguga, kanye nokuhlolwa kwemvelo, izindlela zokuqapha izinga lokushisa eziphelele kanye nokuvikela, kanye nohlelo oluphelele lokuqinisekisa ukuphepha olunekhwalithi elandelekayo. Ukukhetha izinhlobo ezihamba phambili embonini ezifanaAmandla e-China Beihaiiqinisekisa ukuthi imikhiqizo yabo ihlolwa ngokuphepha kukagesi ngendlela ehlelekile, ukuhlolwa kokuguga, kanye nokuqinisekiswa kokuvumelana okuphelele, okuholela ekuzinzeni nasekuphepheni okuphezulu, futhi kunciphisa kakhulu ingozi yokushisa ngokweqile kanye nezinkinga zokuthintana.

Uma unemibuzo mayelanaiziteshi zokushaja ze-ev or isitoreji samandla, noma uma udinga ulwazi olwengeziwe, sicela usishiyele umlayezo noma usithinte ngolwazi lokuxhumana lwewebhusayithi. Sizokuphendula ngokushesha okukhulu.
