Ingaba kuqhelekile ukuba ikheyiji kunye nentambo yokutshaja yesikhululo sokutshaja zibe shushu xa zitshajwa, okanye ingaba yingozi kukhuseleko?

Ngokuthandwa kakhulu kwezithuthi ezintsha zamandla,itshaja ye-ev yasekhayakwayeisikhululo sikawonke-wonke sokutshajaziye zaba zizixhobo esizisebenzisa yonke imihla. Abanini beemoto abaninzi badibana nale ngxaki xa betshaja: “Isibhamu sokutshaja sivakala sishushu xa usichukumisa, kwaye isingxobo sesikhululo sokutshaja siyafudumala okanye sishushu. Ingaba oku kuqhelekile?Eli nqaku liza kunika uhlalutyo lobuchwephesha nolupheleleyo lwale ngxaki.

I. Isiphelo: Ukufudumeza kakhulu ≠ Ingozi, kodwa Ukufudumeza kakhulu yingozi efihliweyo

Nokuba yiyo naUkutshaja ngokukhawuleza kwe-DC or I-AC itshaja kancinci, iintambo kunye nezihlanganisi ziya kuvelisa ubushushu obukhuselayo phantsi kombane ophezulu. Njengeetshaja zefowuni kunye neeadaptha zamandla zelaptop, ukuvelisa ubushushu yinto ebonakalayo, ayikokungasebenzi kakuhle.

Nangona kunjalo, ukuba ukunyuka kwamaqondo obushushu kudlula umlinganiselo ofanelekileyo, oko kubonisa ingxaki enokubakho: njengokungonelanga kwendawo yobhedu enqamlezileyo kwintambo, iindawo ezingasebenzi kakuhle zokudibanisa, okanye umlomo wokutshaja ogugayo. Ezi zinto zinokubangela ukwanda ngokukhawuleza kobushushu bendawo, okunokubangela ukutsha, ukuqhekeka, okanye nomlilo.

II. Kutheni izixhobo zokutshaja zivelisa ubushushu?

Nokuba yintoIsitishi sokutshaja se-ACokanyeIsikhululo sokutshaja ngokukhawuleza seDC, zombini kufuneka ziphathe umsinga omkhulu oqhubekayo ngexesha lokusebenza. Ii-conductors zinokumelana, kwaye ubushushu buyaveliswa xa umsinga uhamba kuzo, njengoko kubonisiwe kwifomyula: P = I² × R

Xa umsinga wokutshaja ufikelela kwi-32A (Isikhululo sokutshaja ekhaya se-7kW) okanye nokuba yi-200A~500A (Inqwaba yokutshaja ngokukhawuleza yeDC), nokuba ukumelana okuphantsi kakhulu kunokuvelisa ubushushu obukhulu. Ke ngoko, ukuveliswa kobushushu okuphakathi yinto eqhelekileyo kwaye ayiweli kudidi lokungasebenzi kakuhle.

Imithombo eqhelekileyo yobushushu ibandakanya:

1. Ubushushu bokumelana neengcingo zokutshaja ngokwazo
2. Ukwehla kwevolthi yoqhagamshelwano kwintloko yokutshaja
3. Ukusasazwa kobushushu obuvela kumacandelo ombane angaphakathi
4. Ubushushu obongezelelweyo obuvela kubushushu obuphakathi kunye nokukhanya kwelanga

Kungoko ke, kuqhelekile ukuba abasebenzisi bazive “beshushu” okanye “beshushu kancinci” xa betshaja.

III. Yintoni eyenza ukunyuka kobushushu okuqhelekileyo?

Imigangatho yoshishino (efana ne-GB/T 20234, GB/T 18487, QC/T 29106) ineemfuno ezithile zokunyuka kwamaqondo obushushuizixhobo zokutshaja. Ukuthetha jikelele:

1. Uluhlu oluQhelekileyo
Ubushushu bomphezulu yi-40℃～55℃: Ukunyuka kobushushu okuqhelekileyo, kukhuselekile ukuyisebenzisa.

55℃～70℃: Iphezulu kancinci kodwa isekwimida eyamkelekileyo kwiimeko ezininzi, ingakumbi xa kutshajwa i-DC enamandla aphezulu ehlotyeni.

2. Uluhlu olufuna unonophelo

＞70℃: Ukuba isondela okanye idlula ukunyuka kobushushu okuvumelekileyo okusemgangathweni, ukutshaja kufuneka kumiswe kwaye isixhobo sihlolwe.

Ezi zilandelayo zithathwa njengeziganeko ezingaqhelekanga:

1. Ukuthambisa irabha okanye iplastiki
2. Ivumba elivuthayo
3. Ukutshintsha kombala weetheminali zesinyithi kwintloko yokutshaja
4. Iindawo ezikufutshane kwisixhumi ziba shushu kakhulu xa zichukunyiswa okanye zingachukunyiswa.

Ezi ziganeko zihlala zinxulumene ngokuthe ngqo "nokungahambelani okungaqhelekanga kokunxibelelana" okanye "iinkcukacha ezinganelanga zentambo" kwaye zifuna uphando olukhawulezileyo.

IV. Zeziphi izinto ezinokubangela ukugqithisa kakhulu?

1. Indawo engaphelelanga yocingo lobhedu kwiintambo:Ezinye iimveliso ezikumgangatho ophantsi zisebenzisa iintambo “ezibhalwe ngobuxoki” ezineendawo ezincinci ezinqamlezileyo zentambo yobhedu, nto leyo ekhokelela ekuxhathiseni okuphezulu kunye nokunyuka kobushushu.

2. Ukwanda kwe-impedance kwiiplagi, iiterminals, kunye nezinye iindawo zoqhagamshelwano:Ukuguguleka nokukrazuka ngenxa yokuxhuma nokukhupha iplagi, ukungaqini kakuhle kwesiphelo, kunye nomgangatho ophantsi wokudibanisa zonke ezi zinto zinokunyusa ukumelana noqhagamshelwano, nto leyo ebangela iindawo ezishushu kakhulu. "Ukufudumala kwekhonkco okugqitha oko kwentambo ngokwayo" yeyona nto ibonakalayo.

3. Uyilo olubi lokusasaza ubushushu kwiindawo zamandla zangaphakathi:Umzekelo, ukungabikho kobushushu obaneleyo kwiirelay, iicontactors, kunye neemodyuli zeDC/DC kuya kubonakala njengobushushu obuphezulu ngaphakathi kwekhava.

4. Impembelelo ebalulekileyo yezinto ezisingqongileyo:Ukutshaja ngaphandle ehlotyeni, amaqondo obushushu aphezulu omhlaba, kunye nokukhanya kwelanga ngqo konke oku kuya kuncedisa ekunyukeni kobushushu okubonwayo.

Ezi zinto zimiselaumahluko wokwenyani womgangatho weenqwaba zokutshaja, ingakumbi ukuthembeka kwezakhono zenkampani zophando nophuhliso, ukukhethwa kwezinto, kunye neenkqubo zokuvelisa.

V. Ungafumanisa njani ukuba kukho naziphi na iingozi zokhuseleko?

Abasebenzisi banokuyivavanya ngokukhawuleza imeko besebenzisa ezi ndlela zilandelayo:

Iziganeko eziqhelekileyo:

• Isibhamu sokutshaja kunye nebhokisi zifudumele xa uzichukumisa.
• Akukho vumba okanye ukuguquka.
• Ubushushu butshintsha kakhulu xa ubushushu obuphakathi busanda.

Iziganeko ezingaqhelekanga:

• Ezinye iindawo zishushu kakhulu xa uzichukumisa, zide zingachukunyiswa.
• Intloko yesibhamu sokutshaja ishushu kakhulu kunentambo ngokwayo.
• Ihamba nevumba elivuthayo, ingxolo, okanye ukuphazamiseka kokutshaja ngamanye amaxesha.
• Intloko yesixhobo sokutshaja iyathambisa okanye itshintsha umbala.

Ukuba kukho into engaqhelekanga eyenzekayo, yeka ukusebenzisa isixhobo ngoko nangoko uze uqhagamshelane nenkonzo emva kokuthengisa okanye ucele enye endaweni yaso.

VI. Ungayikhetha njani iSitishi sokuTshaja?

Izikhululo zokutshaja izithuthi zombanekubandakanya iinkalo ezininzi zobugcisa, kuquka umbane ophezulu, ukhuseleko lombane, ukufakelwa kombane, kunye nolawulo lobushushu, okubeka iimfuno eziphezulu kakhulu kuphando nophuhliso kunye nokuveliswa. Abavelisi abaziwayo baneengenelo ezibalulekileyo kwezi ndawo zilandelayo: iinkcukacha ezichanekileyo zekhebula (akukho mxholo wobhedu obhengezwe ngobuxoki), iintloko zokutshaja ezithembekileyo kunye neenkqubo zokuplata ixesha elide, ukunyuka kobushushu okuqatha, ukuguga, kunye novavanyo lokusingqongileyo, iindlela zokujonga ubushushu kunye nokukhusela ngokupheleleyo, kunye nenkqubo epheleleyo yokuqinisekisa ukhuseleko enomgangatho olandelekayo. Ukukhetha iimpawu eziphambili kushishino ezifanaAmandla eTshayina eBeihaiiqinisekisa ukuba iimveliso zabo zivavanyelwa ukhuseleko lombane ngendlela ecwangcisiweyo, zivavanywa ngokwaluphala, kwaye ziqinisekiswe ukuba zisebenza kakuhle, nto leyo ekhokelela ekuzinzeni nasekukhuselekeni okuphezulu, kwaye inciphisa kakhulu umngcipheko wobushushu obugqithisileyo kunye neengxaki zoqhagamshelwano.
