Lid landing gear box body is formed with the motor gearbox. When the furnace cover needs opening , simply press the button in the control box then the furnace cover will descend at a uniform speed .For the sake of safety ,two movements institutions tops trip switch are mounted in the carburizing EAF .When the furnace cover is ascending , the lower movements institutions tops trip switch will automatically cut off the seepage carbon EAF control cabinet main circuit power supply, forcing the heating elements stop working since the power is cut off, The upper switch is used to restrict the height of the movements axis ,it can prevent the movements pumped up too high to cause theelevating screw abscisicing from the gear box.

炉盖升降机构由电机齿轮箱组成，当需要开启炉盖时，只需按下控制箱上的按组，炉盖即以均速上升下降，为了安全起见，在渗碳电炉升降机构上装设有两个行程开关，当炉盖上升时，下边的行程开关自动切断渗碳电炉控制柜主回路电源，使加热元件断电停止工作，上边的行程开关则限制升降轴升起的高度，以防升降抽升起过高，升降丝杆脱出齿轮箱。

The main purpose of this thesis is to research and develop three different kinds of battery chargers of resonant-switch converters. Starting with the zero voltage switch and the zero current switch converters, which employ the quasi-resonant converter technique, we gain the best parameters of the resonance components from the characteristic curve diagrams of these two converters. Then we design battery chargers based on these two structures and use them to experiment on lead-acid batteries.

中文摘要本论文之主要目的在於研制三种不同的共振开关式转换器蓄电池充电器，先探讨半共振式技术的零电压以及零电流转换器，利用这两种转换器的特性曲线图设计出共振元件最佳的参数值，以这两种架构作为蓄电池充电器，来对铅酸蓄电池做充电测试，经实验测得，零电压切换半共振式降压型转换器之充电器的开关在零电压的时候导通和截止。
