I-Solid State High Frequency Welder Overview

I-Electric Resistance Welding (ERW) yeyona ndlela iphambili yokuvelisa umbhobho wentsimbi, kwaye i-high frequency welder sisixhobo esingundoqo sale nkqubo yokuvelisa. Okwangoku, i-vacuum tube frequency ephezulu iye yatshintshwa ngokusisiseko sisimo esiqinileyo (transistor) frequency high, kunye ne-slid state high frequency supply power ngokusisiseko isekwe kule migaqo ilandelayo:

Isigaba sesi-3(A B C)-Ukulungisa-Ukutyhala i-DC-Smooth DC-Inverter-High frequency AC-Resonance-Output

Ngokomgaqo wobugcisa, ulwakhiwo, kunye namacandelo aphambili e-slid state frequency high, yahlulwe yaba ziindidi ezahlukeneyo:

1. Ngokomgaqo we-inverter resonance: i-parallel resonance kunye ne-resonance series. Njengoko kubonisiwe ngezantsi:

Iresonance enxuseneyo   Uthotho lweresonance

Phawula: C-tanki yesekethe capacitor

Ikhoyili ye-L-Induction

2. Ngokwesixhobo soguqulo: i-low-voltage MOS, i-high-voltage MOS, i-SIC-MOS

3. Ngokohlobo lokulungisa: i-SCR rectifier, i-diode + IGBT

4 Ngokwesakhiwo sendibano: I-compact (Yonke-kwinye) i-welder, i-welder eyahluliweyo, i-welder eyakhelwe ngaphakathi, i-welder yangaphandle ye-transformer, njl.
