Joalo ka ha bohle re tseba, molemong oa polokeho, li-transformer tsa hona joale tse mahareng le tse phahameng liteisheneng tsa liteko tsa transformer hangata li beoa sethaleng lipakeng tsa transfoma e mahareng le sefetoleli se lekiloeng. Hobane bophahamo ba sethala bo pakeng tsa 2-4m, ho thata haholo ho fetola sebaka sa khokahano ho ea holimo le tlase sethaleng.

Lilemong tsa morao tjena, ho na le litsela tse 'maloa tsa ho rarolla bothata bona indastering ea malapeng, e sa khotsofatseng

(1) Transformer ea hona joale e arotsoe ka likarolo tse 2-3 ka lekhetlo la pele le likarolo tse 3-4 ka lekhetlo la bobeli. Ea bobeli e ka fetoloa ka ho fetola lipompo. E fokotsa palo ea ho fetoha hanngoe, empa ka mor'a tsohle, e tlameha ho fetola mohala le ho tima sethaleng hang, e leng ho eketsang ntlha e sa sireletsehang bakeng sa basebetsi ba liteko.

(2) E ka sebelisoa e le mochine o fetolang lipompo tsa motlakase tse phahameng haholo. Sefetoleli le transformer ea hona joale li ikemetse ho tse ling 'me li hokahane le bar ea koporo. Phetoho e phahameng ea motlakase e na le litšenyehelo tse phahameng, sekhahla se phahameng sa ho hloleha le ho se tšepahale hantle. Phallo e sa fellang e ka holimo ho 50pc. Ha ho letho le fokolang.

(3) Baetsi ba bang ba entse lisebelisoa tsa ho kopanya tsa transfoma ea hajoale le mochini oa ho fetola lipompo. E shebahala e kopane, empa boholo ba bona bo senyehile ka lebaka la ho hloleha ha switjha nakong ea tiisetso, ho fella ka ho emisa tlhahiso.

Lilemong tsa morao tjena, k'hamphani ea rona e thehile mofuta o mocha oa transformer ea hona joale ho latela litlhoko tsa basebelisi ba kantle ho naha

(1) Ka ho feletseng sebakeng sa bobeli sa ho fetola, ho fetola mojaro, mochineng oa bobeli oa ho laola motlakase, ho bonolo haholo ho o sebelisa, 'me o boloka sesebelisoa sa mantlha ka sekhahla se phahameng sa ho hlōleha.

(2) Ho lumellana le analyzer ea matla: boemo ba bobeli bo lekantsoeng ke 1a, eseng 5A. U sebelisa analyzer ea matla, boemo ba bobeli bo lekantsoeng bo ka ba 1a. Ho nka mohlala oa motlakase oa W-3000 e le mohlala, pampiri ena e hlalosa ho ikamahanya le maemo a mofuta ona oa transformer ea hona joale le analyzer ea matla: mocha oa hona joale oa W-3000 motlakase analyzer o na le litsela tse peli tse kholo le tse nyenyane, 'me mocha o monyenyane oa hona joale o khethiloe. Hona joale e lekantsoeng ke 5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 500mA, 1A le 2a, e nang le li-gear tse 9 ka kakaretso, tse ka fetohang ka mokhoa o ikemetseng ka hona joale. E ka fetoloa ho transformer ea hona joale ea 1a ea bobeli.

Phetoho ea ho kenya letsoho ea mocha o monyenyane oa hona joale oa W-3000 analyzer ea matla ke 0.5 Ω, 'me impedance ea bobeli ea potoloho ke 0.3 Ω ka ho fetisisa, kahoo tlhahiso e lekantsoeng e lokela ho ba 0.6-0.8va.

(3) Ka lebaka la mefokolo ea tekheniki, tekanyo ea morao-rao e lekantsoeng: IMAX / Imin ≤ 400, bona Letlapa la 1 le tafole ea 2 bakeng sa lintlha.

(4) Phoso: ka keketseho ea mefuta ea hona joale, boemo ba ho nepahala bo eketseha ho tloha ho 0,2 ho ea ho 0.01. Tšobotsi ena e loketse feela tlhahlobo ea transformer. Joalo ka ha bohle re tseba, hobane ntlha ea matla ea tlhahlobo ea ho se be le moroalo e ka tatellano ea 0.2, ha ho hlokahale transfoma e nepahetseng haholo. Ka nako ena, sebaka se tlaase sa 50A le ka tlase se sebelisoa, 'me ho nepahala ho lekane. Ntho ea matla ea teko ea mojaro e tlaase haholo (ho fihlela ho 0.02-0.01), e hlokang ho nepahala ho phahameng ha transformer. Ka nako ena, karolo e phahameng ea 100A le holimo e sebelisoa, 'me ho nepahala ho phahame haholo, ho fihlela boemong ba 0,01.

Ha IMAX / Imin ≤ 400, maemo a ho nepahala a likarolelano tse fapaneng tsa hajoale a bontšoa ho Lethathamo la 1 le tafole ea 2.
