Lipotso Tse Botsoang Khafetsa Mabapi le Insulation Resistance Teste

Teko ea Insulation Resistance Tester e loketse ho lekanya boleng ba khanyetso ba lisebelisoa tse fapaneng tsa ho itšireletsa le ho hanyetsa li-insulation tsa li-transformer, li-motors, lithapo le lisebelisoa tsa motlakase, ho netefatsa hore lisebelisoa tsena, lisebelisoa tsa motlakase le likhoele li sebetsa maemong a tloaelehileng ho qoba ts'isinyeho ea motlakase. Tšenyo.
Mathata a Tloaelehileng a Insulation Resistance Tester ke a Latelang:
 
1. Ha U lekanya Khanyetsano ea Moroalo oa Capacitive, Kamano ke Efe Pakeng Tsa Potoloho e Khutšoane ea Hona joale ea Insulation Resistance Tester le Data e Lekanyelitsoeng, Hona Hobane'ng?
 
Boholo ba Potoloho e Khutšoanyane ea Potoloho ea Hona Joale ea Insulation Resistance Tester e ka Bontša boholo ba khanyetso ea ka hare ea Mohloli o Phahameng oa Voltage ka hare ho Megger.
 
Liteko tse ngata tsa Insulation li Lebisa Meroalo e Matla, joalo ka Lithapo tse telele, Motors tse nang le mapheo a mangata, le li-transformer.Ka hona, Ha Sepheo se Lekanyelitsoeng se na le Bokhoni, Qalong ea Ts'ebetso ea Teko, Mohloli o Phahameng oa Voltage ho Teko ea Insulation Resistance Tester e tlameha ho lefisa Capacitor ka khanyetso ea eona ea ka hare, 'me butle-butle e lefisa motlakase ho sephetho se eketsehileng sa Voltage e phahameng ea The. Insulation Resistance Tester..Haeba Boleng ba Capacitance ba Sepheo se Lekanyelitsoeng bo le Bongata, Kapa Khanyetsano ea ka hare ea Mohloli o Phahameng oa Voltage e kholo, Ts'ebetso ea ho tjhaja e tla nka nako e teletsana.
 
Bolelele ba eona bo ka khethoa ke Sehlahisoa sa R ​​Inner le C Load (Unit: Ea Bobeli), Ke hore, T = R Inner * C Mojaro.
 
Ka hona, nakong ea teko, hoa hlokahala ho tjhaja moroalo o joalo oa capacitive ho teko ea motlakase, 'me lebelo la ho tjhaja DV/Dt le lekana le karo-karolelano ea ho tjhaja ha hona joale ho isa moroalo C. Ke hore, DV/Dt= KEA BONA.
 
Ka hona, ha ho na le khanyetso ea ka hare, 'me ha nako e ntse e ea ho tjhaja, ka potlako liphello tsa liteko li tla tsitsa.
 
2. Mosebetsi oa Lehlakore la "G" la Ponahalo ke Eng?Sebakeng sa Teko se Phahameng ka ho Fetisisa le se hanyetsanang haholo, Hobaneng ho Hlokahala ho Hokela Seteishene sa "G" Ka Ntle?
 
Qetello ea "G" ea Bokaholimo ke Setsi sa Tšireletso.Mosebetsi oa Setsi sa Tšireletso ke ho Tlosa Tšusumetso ea Mongobo le Litšila Tikolohong ea Teko ho Liphetho tsa Tekanyo.Seteishene sa Kantle sa "G" se feta ho lutla ha hona joale ha sehlahisoa se lekiloeng, e le hore ho lutla ha hona joale ho se ke ho fete le potolohong ea liteko tsa kantle, 'me ho felise phoso e bakiloeng ke ho lutla ha hona joale.G Terminal e sebelisoa ha ho etsoa liteko tse phahameng tsa ho hanyetsa.
 
Ha re bua ka Kakaretso, Seteishene sa G se ka nkuoa e le se Phahameng ho Feta 10G.Leha ho le joalo, Lekhalo lena la Khanyetso ha le na bonnete.Ha e hloekile ebile e omme 'me Bolumo ea Ntho ea Teko e Nyenyane, e ka tsitsa ntle le ho lekanya 500G Qetellong ea G.Libakeng tse Mongobo le tse Litšila, Boleng bo Tlase ba Khanyetso bo boetse bo Hloka Q End.Haholo-holo, haeba u fumana hore liphetho li thata ho tsitsisa ha u lekanya khanyetso e phahameng, u ka nahana ka ho sebelisa G terminal.Hape hlokomela hore The Shielding Terminal G ha e ea hokahanngoa le Lera le Sireletsang, Empa le Insulator Pakeng tsa L le E Kapa Mohala o nang le Mehala e Mengata, Eseng Mehala e Meng e Tekong.
 
3. Ke Hobane'ng ha ho sa Hlokehang Feela ho Lekanya Boleng bo Hloekileng ba ho hanyetsa ha o lekanya Insulation, empa hape le ho lekanya tekanyo ea ho monya le index ea polarization.Ntlha ke Eng?
PI Ke Polarization Index, E Bolelang Papiso Pakeng Tsa Insulation Resistance Of 10 Minutes Le Insulation Resistance Of 1 Minute Nakong ea Insulation Test;
 
DAR Ke Dielectric Absorption Ratio, E bolelang Papiso pakeng tsa Insulation Resistance Of 1 Minute le Insulation Resistance of 15s Nakong ea Insulation Test;
 
Tekong ea Insulation, The Insulation Resistance Value Ka Nako e itseng e ke ke ea Bonahatsa ka botlalo Mosebetsi oa Insulation oa Sample ea Teko.Sena se Bakoa ke Mabaka A Mabeli A Latelang.Ka lehlakoreng le le leng, Khanyetso ea Insulation ea Mosebetsi o Tšoanang oa Thepa ea Insulation e Nyenyane Ha Molumo o le moholo., The Insulation Resistance e Hlaha Ha Molumo o le Monyenyane.Ka lehlakoreng le leng, Thepa ea Insulating e na le Ts'ebetso ea Karolelano ea ho monya le Ts'ebetso ea Polarization ea Tefiso ka mor'a hore ho sebelisoe motlakase o phahameng.Ka hona, Sisteme ea Matla e Hloka Tekanyo ea Karo-karolelano ea Li-R60 le R15, Le Polarization Index-Karo-karolelano ea R10min le R1min Tekong ea Insulation ea Li-transformer tse kholo, lithapo, Motors le Liketsahalo tse ling tse ngata, 'me u sebelise sena. Lintlha tsa ho khetholla Insulation e ntle kapa e mpe.
 
4. Ke Hobane'ng ha The Electronic Insulation Resistance Tester e ka Hlahisa Motlakase o Phahameng oa DC Ha o Matlafatsoa ke Libetri tse 'maloa?Sena se ipapisitse le Molao-motheo oa Phetoho ea DC.Motlakase oa Phepelo ea Motlakase o Phahamisetsoa ho Motlakase oa Motlakase oa DC ka Boost Circuit Processing.Motlakase o Phahameng o Hlahisitsoeng o Phahameng empa Matla a Tsoang a Manyane (Matla a Tlase le a Hona Joale a Nyenyane).
 
Tlhokomeliso: Esita le Haeba Matla a Le Manyane Haholo, Ha ho kgothaletswe ho ama ka boyena Testing Probe, ho sa ntse ho tla ba le maikutlo a hlabang.
