箱式線圈：低壓繞組采用整段銅箱，連同F級的匝繞緣在專用低壓箱繞機(jī)上繞制，箱式線圈較好地解決了低電壓，大電流線圈繞產(chǎn)品短路應(yīng)力大，安匝不平衡，散熱效果差，存在繞制螺旋角，人工焊接質(zhì)量不穩(wěn)定的突出問題。同時我公司繞組端部用樹脂灌封，固化成形，防潮防污，引線銅排經(jīng)氬弧焊自動焊接。

溫控裝置:  變壓器采用BWDK系列信號溫度計，測溫元件埋設(shè)在低壓線圈上半部，可自動檢測并巡回顯示相線圈各自的工作濕度。并且有超溫報警和跳閘功能。

Box coil：low voltage winding adopts segmental copper foil,along with F grade in the low-pressure foil insulation turms on special around the system.Foil type coils has solved the low voltage,large current coil short-circuit stress around the product,Ann circle imbalance,cooling effect is poor,exist around the system spiral angel,artificially welding quality unstable outstanding problems.

At the same time company winding ends potting with resin. curing forming,moistureproof antifouling.Fuses copper platoon diameter argon arc welding automatic welding

Temperature control device: transformer USES BWDK series Temperature sensor signal thermometer,buried in the low-pressure coil,upper automatic detection and touring show phase of their respective working temperature coiI and overtemperature alarm and tripped function.
