UHLOBO UHLOBO OLUQINILE ESIMO ESIPHEZULU IFREQUENCY WELDER

I. Umgomo wokusebenza uboniswa emfanekisweni olandelayo:

I-thyristor rectifier voltage regulation technology iyamukelwa, futhi ayikho i-transformer yokufaka. Ibhuloho le-inverter lamukela i-MOS ene-voltage ephezulu, futhi isekethe yethangi ithatha uchungechunge lwesakhiwo se-resonant.

Ibanga lamandla: 30KW ~ 2000KW

Izinzuzo:

1. Ubuchwepheshe be-pulse yokulahlekelwa kwebhuloho le-inverter bungasetshenziselwa ukulungisa i-impedance yomthwalo, futhi ukuphuma kwamandla akuthintwa kancane umthwalo

2. Kunempahla eningi yesitoko embonini, futhi kunezisebenzi eziningi ezinakekelayo ezindaweni eziningi, ezilungele ukulungiswa.

3. Ayikho i-transformer yokufaka, futhi isisindo sonke nevolumu kuncane

4. Indlela yokufaka nayo ihlukaniswe yaba i-welder ehlukanisiwe kanye ne-compact welder, kodwa ivolumu inkulu kunaleyo ye-parallel circuit, futhi izindleko zempahla nazo ziphakeme.

Uchungechunge oluhlukanisiwe lwe-welder: luhlukaniswe ngamakhabethe amabili we-rectifier kanye ne-inverter.ngokuvamile afanele imishini emikhulu yamandla.

I-Series compact (all-in-one) welder: i-rectifier ne-inverter ehlanganiswe kukhabhinethi eyodwa.ngokujwayelekile ifanele imishini yamandla aphansi.

II. Uchungechunge lohlobo oluqinile-isimo esiphakeme sokuvikela ishayela (ukulahlekelwa ukushaya kwenhliziyo) isethulo somgomo

Ijubane lokukhiqiza lamapayipi ashiselwe lithinteka yizici eziningi. Izici ezibucayi kakhulu amandla okushisela kanye nobukhulu bodonga lwamapayipi nobubanzi. Uma isimo sepayipi sihlala sinjalo, amandla aphezulu, isivinini esisheshayo; Njengoba amandla engashintshiwe, lapho ubukhulu bodonga bukhulu kanye nobubanzi, isivinini sihamba kancane. Ukuze ukwandise isivinini, kuyinto efiselekayo ukuthi i-welder ihlale igcina ukuphuma kwamandla okugcwele. Amandla we-welder ephezulu-frequency alingana nomkhiqizo we-voltage yokusebenza kanye namanje. Ngosayizi othile we-welder, kunomkhawulo omkhulu ku-voltage yayo yokusebenza kanye namanje (cishe ilingane nesilinganiso esilinganiselwe), esingenakudlula kakhulu. Noma iyiphi ipharamitha ephakeme kakhulu ingase ibangele umonakalo kumshiseli. Ngakho-ke, i-voltage ne-current ifinyelela i-voltage elinganiselwe yamanje kanye nesilinganiso se-welder high-frequency ngesikhathi esifanayo, ukuze amandla alinganisiwe akwazi ukuphuma, okungukuthi, amandla aphezulu avunyelwe welder.

Ngaphansi kwezimo ezijwayelekile, ukulungiswa kokufakelwa kwamandla we-welder kufinyelelwa ngokulungisa i-voltage yokusebenza, futhi ubukhulu bamanje obusebenzayo bunqunywa i-voltage kanye nokuvinjelwa kwesifunda sethangi. Ngenxa yokushintshwa kohlobo lwepayipi kanye nomehluko we-inductor, induku kazibuthe, ne-angle yokuvula, i-impedance ye-tank circuit (i-capacitance ne-inductor) ihlukile. Ngakho-ke, kunzima ukufeza umdlalo ongcono kakhulu phakathi kwe-voltage kanye ne-current of the high-frequency welder (futhi ngesikhathi esifanayo ukufeza ukulinganisa), futhi kunzima ukufeza amandla amakhulu.

Ukuze uxazulule le nkinga, ukunikezwa kwamandla we-high-frequency ene-resonance yochungechunge kungasetshenziswa ukulungisa okwamanje ngokulungisa i-inverter pulse. Ngokuvamile, ama-pulses amabili ashayela i-MOS inverter ayashintsha futhi aqhubekayo, uma kukhona ama-pulses, i-MOS ivuliwe futhi ibhuloho le-inverter linomphumela wamanje.Uma kungekho shayela, i-MOS ivaliwe, futhi ibhuloho le-inverter. ayikhiphi yamanje. Ngale ndlela, uma i-pulse eyodwa ivinjiwe njalo ama-pulses ambalwa, ingxenye yamanje ingavinjelwa, futhi isilinganiso samanje sizoncishiswa, esilingana nokwanda kokuvinjelwa kwesekethe ye-tank, ukuze kube nokwenzeka finyelela ukufana okuhle kakhulu phakathi kwe-voltage neyamanje.

Lapho umthamo omkhulu wamandla we-high-frequency welder ungadingeki, okwamanje ungancishiswa ngokunciphisa i-pulse, ukwandisa i-impedance, futhi wenze kuphela i-voltage ifinyelele inani elilinganiselwe. Le ndlela yokusebenza yamanje yamandla aphansi naphezulu ingathuthukisa isici samandla we-high-frequency welder, inciphise ukulahleka kwamandla asebenzayo kanye nokuphazanyiswa kwe-harmonic.

I-high-frequency welder enobuchwepheshe bokuvikela i-pulse idinga kuphela ukushintshwa kwebhodi lokulawula inverter kanye nezingxenye ezithile zangaphandle, ngokushintsha okuncane kwesakhiwo nokubukeka. Futhi ayinawo umthelela ku-high-frequency.

Kodwa-ke, ngenxa ye-pulse engapheli, i-current ayizinzile, engase ifake ingcindezi ezingxenyeni ezifana nokuhlunga ama-capacitor.
