Onye na-enyocha ihe mkpuchi mkpuchi dabara adaba maka ịlele uru nguzogide nke ihe mkpuchi dị iche iche yana nguzogide mkpuchi nke transformers, moto, eriri na ngwa eletriki, iji hụ na ngwa ndị a, ngwa eletriki na ahịrị na-arụ ọrụ n'ọnọdụ nkịtị iji zere ujo ọkụ eletrik, ihe ọghọm na akụrụngwa. Mmebi.
Nsogbu ndị a na-enwekarị nke ihe nleba anya mkpuchi mkpuchi bụ ndị a:
1. Mgbe ị na-atụle nguzogide ibu nke capacitive, gịnị bụ mmekọrịta dị n'etiti mmepụta Short-Circuit ugbu a nke ihe nleba anya mkpuchi mkpuchi na data a tụrụ atụ, na gịnị kpatara?
Ogo nke mmepụta Short-Circuit dị ugbu a nke onye na-enyocha ihe mgbochi mkpuchi nwere ike igosipụta nha nke nguzogide ime nke isi iyi voltaji dị elu n'ime Megger.
Ọtụtụ Nnwale mkpuchi mkpuchi na-ezubere ibu ndị nwere ike, dị ka eriri ogologo ogologo, moto nwere ikuku ikuku karịa na ndị ntụgharị.Ya mere, mgbe ebumnuche a tụrụ atụ nwere ikike, na mbido usoro nnwale ahụ, isi iyi dị elu na ihe nleba anya mkpuchi mkpuchi ga-anarịrị capacitor site na nguzogide ime ya, ma jiri nwayọ na-anata voltaji ahụ na mgbakwunye elu voltaji nke ọzọ. Ihe Nnwale Nguzogide Mkpuchi..Ọ bụrụ na ọnụ ahịa ikike nke ebumnuche atụtara buru ibu, ma ọ bụ nguzogide ime nke isi iyi voltaji dị elu, usoro ịchaji ga-ewe ogologo oge.
Enwere ike ikpebi ogologo ya site na ngwaahịa R Inner na C Load (Unit: Nke abụọ), ya bụ, T = R Inner * C Load.
Ya mere, n'oge ule ahụ, ọ dị mkpa iji kwụọ ụgwọ dị otú ahụ capacitive ibu na voltaji ule, na Nchaji Speed DV/Dt bụ nha nha nha nke chaja ugbu a I ruo Capacitance Ibu C. Ya bụ, DV/Dt = I/C.
Ya mere, nke nta nke nguzogide ime na ka ịchaji dị ugbu a, ngwa ngwa nsonaazụ ule ahụ ga-akwụsi ike.
2. Gịnị bụ ọrụ nke akụkụ "G" nke ọdịdị ahụ?Na Gburugburu Ule Ule dị elu na Nguzogide dị elu, kedu ihe kpatara eji achọ ijikọ ọdụ “G” na mpụga?
Ọgwụgwụ “G” nke elu ahụ bụ ọdụ nchekwa.Ọrụ nke Terminal Shielding bụ iwepụ mmetụta nke iru mmiri na unyi na gburugburu ule na nsonaazụ nha.Mpụga “G” Mpụga na-agafe nhụfu nke ngwaahịa a nwalere ugbu a, nke mere na nkwụsị nke ugbu a anaghị agafe na sekit ule mpụga, wee kpochapụ njehie nke ntapu ugbu a kpatara.A na-eji ọdụ G mgbe a na-anwale nguzogide dị elu.
N'ikwu okwu n'ozuzu, enwere ike ịtụle G Terminal dị elu karịa 10G.Agbanyeghị, oke nguzogide a ejighị n'aka.Mgbe ọ dị ọcha ma kpọọ nkụ na olu nke ihe nnwale ahụ pere mpe, ọ nwere ike kwụsie ike na-enweghị atụ 500G na njedebe G.Na gburugburu iru mmiri na unyi, Uru Nguzogide dị ala na-achọkwa njedebe G.Kpọmkwem, Ọ bụrụ n’ịchọpụta na nsonaazụ ya siri ike ịkwụsi ike mgbe ị na-atụ nguzogide dị elu, ị nwere ike ịtụle iji G Terminal.Marakwa na Ejikọghị Terminal G Shielding na Layer Shielding, kama na Insulator n'etiti L na E ma ọ bụ na waya nwere ọtụtụ eriri, ọ bụghị na waya ndị ọzọ na-anwale.
3. Gịnị kpatara na ọ bụghị naanị na achọrọ ka ịlele uru nguzogide dị ọcha mgbe ị na-atụ ihe mkpuchi, kamakwa iji tụọ ọnụọgụ Absorption na Index Polarization.Kedu ihe bụ isi?
PI bụ Index Polarization, nke na-ezo aka na ntụnyere n'etiti nguzogide mkpuchi nke nkeji 10 na mkpuchi mkpuchi nke 1 nkeji n'oge ule mkpuchi;
DAR bụ Dielectric Absorption Ratio, nke na-ezo aka na ntụnyere n'etiti nkwụsị mkpuchi mkpuchi nke 1 nkeji na mkpuchi mkpuchi nke 15s n'oge ule mkpuchi;
N'ime Nnwale mkpuchi mkpuchi, Uru Nguzogide mkpuchi mkpuchi n'oge ụfọdụ enweghị ike igosipụta nke ọma ọrụ mkpuchi nke ihe nlele ule.Nke a bụ n'ihi ihe abụọ a.N'otu aka, Nguzogide mkpuchi nke otu ọrụ nke ihe mkpuchi ahụ dị ntakịrị mgbe olu dị ukwuu., Nguzogide mkpuchi na-apụta mgbe olu dị ntakịrị.N'aka nke ọzọ, ihe mkpuchi ahụ nwere usoro nke absorption Ratio na usoro polarization nke ụgwọ mgbe etinyere nnukwu voltaji.Ya mere, Sistemụ Ike chọrọ nha nke oke absorption-Ratio nke R60s na R15s, yana Index Polarization-Ratio nke R10min na R1min n'ule mkpuchi mkpuchi nke isi transformers, cables, Motors na ọtụtụ oge ndị ọzọ, wee jiri nke a. Data iji chọpụta ihe mkpuchi ahụ dị mma ma ọ bụ ihe ọjọọ.
4. Gịnị kpatara Onye Nnwale Nguzogide Eletrọnịkị nwere ike wepụta voltaji dị elu DC mgbe ọtụtụ batrị na-akwado ya?Nke a dabere na ụkpụrụ nke ntụgharị DC.A na-ebuli voltaji na-ebunye ike dị ala ka ọ bụrụ voltaji DC dị elu site na nhazi okirikiri.Voltaji dị elu emepụtara dị elu mana ike nrụpụta dị obere (Obere ike na obere ugbu a).
Mara: Ọbụlagodi na ike ahụ pere mpe, A naghị atụ aro ka ị metụ nyocha nnwale ahụ n'onwe ya, a ka ga-enwe mmetụta Tingling.
