Ukuphucula i-Grounding: Ukwenza iNkqubo yakho yokuGcinwa kwamandla oRhwebo ikhuseleke

Kumacandelo ezorhwebo kunye nezoshishino, iinkqubo zokugcina amandla ziye zaba ngundoqo wonikezelo lwamandla kunye nokulawulwa kweemfuno kunye nokuhlanganiswa kwamandla acocekileyo. Abagcini nje ngokulawula ngokufanelekileyo ukuguquguquka kwegridi kunye nokuqinisekisa unikezelo lwamandla oluzinzile, kodwa bakhuthaza ukuphuculwa kwesakhiwo samandla. Ucingo lokumisa lunokwazisa iingozi ezinokubakho zokhuseleko ezifana nombane ongatshintshiyo kunye nokuvuza kwangoku okunokuthi kuveliswe yinkqubo emhlabeni, ukukhusela izixhobo kunye nabasebenzi ekutshatyalalisweni kombane kunye nolunye ukulimala, kwaye uqinisekise ukusebenza ngokukhuselekileyo kunye nokuzinza kokugcinwa kwamandla. inkqubo.

Uhlalutyo lwangoku lokuthwala amandla kwiikhabhinethi zokugcina amandla kwimizi-mveliso kunye nezorhwebo, amandla enkqubo ngokubanzi afikelela kwi-100KW, umlinganiselo olinganisiweyo wombane we-840V ukuya kwi-1100V. le mvelaphi, umthamo wokugcwala kocingo lokumisa ibe yeyona nto iphambili yokuqwalaselwa ekukhethweni. Ngokukodwa, kwi-840 V, umthamo opheleleyo wangoku malunga ne-119 A, ngelixa i-1100 V, umthamo opheleleyo wangoku malunga ne-91 A. Ngokusekelwe kule nto, kucetyiswa ukuba kusetyenziswe abaqhubi bezobhedu be-3 AWG (26.7 mm2) nangaphezulu ukuya qinisekisa ukuba iintambo zinomthamo owaneleyo wokuthwala ngoku, ukuze inkqubo ikwazi ukugcina ukhuseleko kunye nokuzinza kunye nokuthintela iingozi zombane ukuba zenzeke, nokuba kukho imithwalo ephezulu okanye impazamo ngequbuliso imisinga.

Uvavanyo lokuziqhelanisa nokusingqongileyo Ngenxa yokuba iinkqubo zokugcina amandla kwimizi-mveliso kunye nezorhwebo zisetyenziswa kakhulu kwiindawo ezingaphandle, iintambo kufuneka zibe nokuxhathisa kakuhle kweqondo lokushisa kunye nokumelana nemozulu ukumelana nobushushu obuphezulu, ukufuma okuphezulu kunye nezinye iindawo ezinokuthi zihlangabezane nenkqubo yokugcina amandla. Kucetyiswa ukuba iintambo ezine-XLPE okanye i-PVC yokugquma kufuneka zibe neqondo lokushisa eliphakathi kwe-105 ° C ukuqinisekisa ukuba naphantsi kweemeko zokunyuka kwamaqondo obushushu ngexesha lokusebenza kwenkqubo, iintambo zisenako ukugcina ukusebenza kwazo kombane kunye namandla omatshini ukuphepha ukusilela kombane okubangelwayo. ngezinto zokusingqongileyo.

Indlela yokukhetha ikhebula Ukongeza, ukusebenza kakuhle okuphezulu kunye nokugcinwa okuphantsi kuye kwaba ngumkhombandlela wophuhliso logcino lwamashishini kunye nezorhwebo, ukuzinza kwentambo kunokuba yingqwalasela ebalulekileyo ekukhetheni iintambo ezikumgangatho ophezulu kunokunciphisa ukuphindaphindeka kokutshintshwa, ukunciphisa ukusebenza. kunye neendleko zokugcina, zokwandisa ukusebenza kakuhle kwenkqubo iyonke. Ngoko ke, kwinqanaba lokukhetha, kufuneka kunikwe ingqwalaselo ephambili kwiimveliso eziye zavavanywa ngokuqatha kunye nokuqinisekiswa kweemarike ukuxhasa ukusebenza okuzinzile kwexesha elide lenkqubo.

Ukusukela ngo-2009,Danyang Winpower Wire & Cable Mfg Co., Ltd. ibilima kwintsimi yeentambo zombane kunye ne-elektroniki phantse iminyaka eyi-15, iqokelela amava oshishino olutyebileyo kunye nokwenziwa kwezinto ezintsha zobuchwepheshe. Sigxile ekuziseni umgangatho ophezulu kunye nezisombululo zeengcingo ezijikelezayo kwiinkqubo zokugcina amandla kwiimarike, imveliso nganye iye yaqinisekiswa ngokungqongqo ngabasemagunyeni baseYurophu naseMelika, kwaye ilungele i-600V ukuya kwi-1500V yeenkqubo zokugcina amandla ombane, nokuba yinto enkulu- isikhululo samandla esikalini sogcino lwamandla okanye inkqubo encinci esasaziweyo, ungafumana ezona zisombululo zocingo zecala ze DC.

Iingcebiso zokukhetha iingcingo ezisezantsi

Kweli xesha lokukhula kwamandla aluhlaza, Winpower Wire & Cable iya kusebenza nawe ukujonga imida emitsha yogcino lwamandla. Iqela lethu lobuchwephesha liya kukubonelela ngoluhlu olupheleleyo logcino lwamandla ogcino lwe-cable kunye nenkxaso yenkonzo. Nceda uqhagamshelane nathi!
