I-150KW State Solid State High Frequency Compact Pipe Welder

Ngenxa yokuba i-thyristor rectifier ithatha ulawulo lokutshintshwa kwesigaba, umgaqo wamandla kukulungelelanisa i-voltage ngokutshintsha i-angle yokuqalisa. Isekethe ifunxa i-sine iliza nge-engile engekhoyo ukusuka kwigridi yamandla, kwaye ishiya enye inxalenye ye-sine wave eneengile engekhoyo kwigridi yamandla. Ngokucacileyo, inxalenye ekhohlo iqulethe inani elikhulu le-harmonics. Kwangaxeshanye, amandla ombane aphantsi ngenxa yamandla ombane ahlukeneyo kunye nezigaba zangoku (esezantsi i-voltage ye-DC yokuphuma, I-low factor factor).

Ubalo lwethiyori kunye novavanyo lubonisa ukuba xa i-angle ye-trigger yesigaba esithathu elawulwa ngokupheleleyo kwisilungisi sebhulorho inguziro, okanye xa isilungisi sebhulorho esingalawulekiyo esenziwe ngeediode sisetyenziswa, i-harmonic eyenziwe incinci kakhulu kwaye amandla amandla aphezulu kakhulu (ngaphezulu kune. 0.9). Nangona kunjalo, kwisicelo esisebenzayo, kufuneka ibe nomsebenzi wokulungelelanisa ngokuqhubekayo i-voltage ye-DC (oko kukuthi, ukulungelelanisa amandla aphumayo), kwaye izixhobo azikwazi ukusebenza kwi-voltage epheleleyo ngonaphakade. Ukuze wenze izixhobo zibe ne-harmonic encinci, eyona nto iphezulu yamandla kunye negunya elihlengahlengiswayo, esinye isixhobo sokulawula umbane kufuneka songezwe emva kwebhulorho engalawulekiyo yokulungisa.

Ngoko ke, emva kophando olunzulu, siye saqulunqa iteknoloji yokulungisa amanani kwaye safumana i-patent yesizwe (zl201520767232. X).

Isigaba sesithathu socingo lwe-380V, i-50Hz AC esetyenziswa kushishino jikelele lulungiswa "yibhulorho yokulungiswa kwesigaba esithathu" (eyakhiwe ngee-diode ezintandathu ze-ZP kunye nokulungiswa kwexesha elinye) ukuze ibe yi-300Hz pulsating DC, emva koko iguqulwe ibe yi-DC egudileyo emva kokucoca i-LC. (eyakhiwe ngokusabela kunye ne-capacitance), kwaye emva koko yaguqulwa yaba yi-AC ene-frequency elawulwayo kunye ne-voltage engaphezu kwe-10 kHz emva kokuguqulwa kunye nokulawulwa kwe-voltage nge-single-phase inverter bridge (eyakhiwe ngamaqela amane e-IGBTs), emva koko iba yi-low-voltage pulsating. I-DC emva kwe-high-frequency transformer step-down and diode rectification (ulungiso lwesibini), kwaye emva koko ibe yi-DC egudileyo ephantsi-voltage emva kokusabela okanye i-capacitor smoothing kunye nokucoca.

Ibhulorho ye-inverter yesigaba esisodwa eyenziwe yi-IGBT inemisebenzi emibini: i-inverter kunye nokulawulwa kombane. Ngamanye amazwi, i-voltage ephumayo inokulungelelaniswa ngokweemfuno zemveliso ngelixa uhlehlisa i-DC ukuya kwi-AC.

I-high-frequency transformer ithatha i-ferrite njengento eqhubayo yamagnetic, kwaye umlinganiselo wenguqu oyintloko uyilwe ngokweemfuno, kunye nomthamo omncinci, ixabiso eliphantsi kunye nokusebenza kakuhle kokuqhuba.

I-TEYES 150KW Solid State Solid State High Frequency Compact Pipe Welder ene-PWM yetekhnoloji yokulungisa amanani inezi nzuzo zilandelayo:

I-1) I-high power factor: i-factor yamandla ≥ 0.92, akukho mfuneko yokongeza izixhobo zembuyekezo yamandla asebenzayo.

2) Ungcoliseko oluphantsi lwe-harmonic: ngokuqhelekileyo, akukho mfuneko yokongeza izixhobo zonyango ezongezelelweyo ze-harmonic

3) Amandla okuvelisa azinzileyo: i-ripple output ≤ 0.2%, kunye ne-burr yombhobho odibeneyo ufana kakhulu.

I-4) Isantya sokukhusela ngokukhawuleza: ixesha lokukhusela i-fault interlocking ≤ 10 μ S. Isixhobo sithembeke ngakumbi.

5) Ukusebenza kwamandla aphezulu: ngenxa yokuba ukulahlekelwa kwamandla okusebenzayo kuncitshisiwe, ukusebenza kakuhle komatshini wonke kuphuculwe.
