中頻點(diǎn)焊機(jī)的技術(shù)優(yōu)勢(shì) </p> <p> 1、焊接質(zhì)量 </p> <p> 工頻交流焊機(jī)的調(diào)節(jié)周期較長(zhǎng)，對(duì)50Hz的電網(wǎng)，焊接時(shí)間調(diào)節(jié)分辨率為20ms。逆變直流點(diǎn)焊機(jī)時(shí)間調(diào)節(jié)分辨率可達(dá)0.25ms(4kHz逆變頻率)，控制精度高。逆變焊機(jī)的反饋控制的響應(yīng)速度明顯加快，輸出穩(wěn)定性好。 </p> <p> 工頻交流焊機(jī)由于電流過零的影響，熱效率低，用晶閘管調(diào)節(jié)電流，當(dāng)電流百分比偏小時(shí)，過零時(shí)間長(zhǎng)，影響更大；逆變直流點(diǎn)焊機(jī)輸出電流為脈動(dòng)直流，在回路電感的作用下為連續(xù)直流輸出，熱效率高，焊接熱輸入穩(wěn)定。 </p> <p> 2、焊接速度 </p> <p> 工頻交流焊機(jī)由于電流過零的影響，加熱時(shí)間相對(duì)較長(zhǎng)。逆變電阻點(diǎn)焊機(jī)為直流輸出，加熱集中，焊接時(shí)間縮短。 </p> <p> 3、節(jié)能效果 </p> <p> 工頻交流點(diǎn)焊機(jī)工作在50Hz，變壓器損耗大，焊機(jī)功率因素低，回路損耗大。逆變焊機(jī)變壓器工作在較高的頻率(1-4kHz)，損耗很小，直流輸出改善功率因素，節(jié)能效果明顯。 </p> <p> 4、設(shè)備體積與重量 </p> <p> 工頻交流焊機(jī)的變壓器鐵心較大，同樣功率條件下設(shè)備較笨重。逆變直流電阻點(diǎn)焊機(jī)變壓器大大減小，設(shè)備較輕巧電流調(diào)節(jié)開關(guān)級(jí)數(shù)的選擇可按焊件厚度與材質(zhì)而選定。浙江大功率儲(chǔ)能點(diǎn)焊機(jī)</p><p
