Izinto ezifunekayo zokuvavanya umgangatho wamandla
Okwangoku, iinkampani zobonelelo ngombane zineemfuno ezingqongqo ngakumbi kumgangatho wamandla.Uphicotho lokusetyenziswa kombane kulwandiso lweshishini okanye ulwakhiwo lweprojekthi entsha ayiseyonto nje yokuba umthamo wenkqubo yamandla kunye nolungiselelo loncedo lombane zezenzululwazi kwaye zisengqiqweni.Impembelelo yesixokelelwano samandla ibeka phambili ezinye iimfuno zovavanyo.Ukunceda amashishini ukuba aphumelele isicelo kwiiprojekthi ezintsha, iCandelo loMgangatho waMandla weZhejiang Hongyan Electric Co., Ltd. libonelela ngovavanyo lomgangatho wamandla kunye neenkonzo zokuhlalutya kwiiprojekthi ezintsha, kubandakanywa imigca yohambo kaloliwe emikhulu, Ukuqhuba uvavanyo lomgangatho wamandla. kunye nocazululo kwizikhululo zothutho lukaloliwe, iiprojekthi zentsimbi yokusila eziko lombane, iziseko zemveliso yamashishini amakhulu, ukusasazwa kwamandla epaki kwangaphambili ucwangciso, izakhiwo zorhwebo, njl. iprojekthi endaweni yokulinda de kube ngumgangatho wamandla Emva kokuba ingxaki ibonakaliswe kwaye inefuthe elikhulu, amanyathelo okulungisa athathwa.
Uvavanyo lomgangatho wamandla lubandakanya ukuvavanywa kwezalathi zomgangatho wamandla ezinje nge-harmonics, ukuguquguquka kwamandla ombane kunye ne-flicker, into yamandla, kunye nenqanaba lesithathu elingalungelelananga ngokulinganisa, ukuhlalutya, kunye nokubala impembelelo yomthwalo wamandla kwinkqubo yamandla yomsebenzisi kwindlela eqhelekileyo yenkqubo. amanqaku oqhagamshelwano., Ingxelo yokuvavanya inokukhutshwa kwiintsuku ze-10 zokusebenza ukuba izinto ezisebenzayo zigqityiwe.
Itshati yokuPhumla yeNkqubo yoVavanyo loMgangatho waMandla
Umxholo woVavanyo:
Ukulinganisa, ukuhlalutya, kunye nokubala impembelelo yomthwalo wamandla kwinkqubo yamandla omsebenzisi kwiindawo zoqhagamshelo eziqhelekileyo zenkqubo, kubandakanywa izikhombisi zomgangatho wamandla ezifana ne-harmonics, ukuguquguquka kwamandla ombane kunye ne-flicker, i-factor factor, kunye nesigaba sesithathu sokungalingani.
Isiseko soVavanyo loMgangatho waMandla
Imigangatho efanelekileyo yenkampani yethu
Isiseko sovavanyo lomgangatho wamandla kuhlalutyo kunye nenkqubo yokubala siya kwamkela imigangatho ehambelana nobulunga bamandla enkampani yethu kunye neshishini lamandla, kubandakanya:
"Umgangatho wamandla-oVumelelekileyo wokungalungelelani kweVoltage yesigaba esiThathu" (GB/T15543-2008)
"Umgangatho wamandla - Ukuguquguquka kweVoltage kunye neFlicker" (GB12326-2008)
"Umgangatho wamandla-Igridi yoLuntu iHarmonics" (GB/T14549-93)
