  固態(tài)高頻焊機(jī)的逆變輸出柜

● 逆變部分由MOSFET單相逆變橋并聯(lián)組成,單橋功率設(shè)計(jì)為120kW/60kW,逆變橋選用積木式方式完成功率疊加,每塊橋板均設(shè)計(jì)為由滑道組成的抽屜式結(jié)構(gòu),方便裝置與修理;

● 選用匹配變壓器完成功率組成,選用次級(jí)諧振、無(wú)焊接變壓器輸出方式,由槽路諧振電容器(低壓)與感應(yīng)器直接諧振,經(jīng)過(guò)輸出極板實(shí)現(xiàn)鋼管焊接所需功率的傳遞。

● 選用密封機(jī)箱,裝置頂置空調(diào)。

Inverter Output Cabinet

● The inverter part is consisted of MOSFET single phase invert bridge in parallel style. Each bridge’s design power is 120 kW/60kW. We adopt building block mode to pile up power, it’s very convenient to install and maintenance because every single bridge board is designed as drawer structure consisted of slideway.

● We adopt matching transformer to realize power combination, also we adopt sub-resonance, no-welding transformer output mode and make resonance directly by tank resonance capacitor (low voltage) and inductor to achieve steel pipe welding power transmission by output lead.

● Use sealed box and install overhead air conditioning.
