西门子6DD1682-0AJ3 数控模块
RC吸收网络：RC吸收网络提供瞬间电压保护电路，以减少dv/dt冲击电压。防止SCR模块的损坏。
E、触发电路：SCR是用一个持续的脉冲触发电路，这个电路是采用光纤和脉冲变压器进行隔离。
F、主真空接触器：主真空接触器是用来切断主电源和SCR回路的，其电压比率是：5KV用于2300—4160V，7.2KV用于6000—7200V，15KV用于10—15KV的软起动器。
应用于顺序控制下的接触器。在正常使用条件下保证其起动次数能够达到设计时非负载状态下的使用寿命。主真空接触器是设计在大起动比率，旁路接触器是设计在紧急起动的比率。10-15KV600A的起动器采用真空拉出式的接触器，其容量为15KV600A。这个控制装置有两个指示灯、三个电流计时器、电流过流继电器，并且有一个电容型器件。旁路接触器装置也有两个指示灯和一个电容跳闸元件。
⒉电子控制系统
HPMV系列电子控制电路分为低压、中高压两部分，并隔离成两个独立的部分。低压电子部分包括控制界面和接口，CPU和主电源板是安装在低压控制室中。
A、CPU主控板：CPU板上装有微处理器和通讯处理器，CPU决定操作功能，根据用户的设定程序和检测反馈信号来进行控制，CPU主板上装有EPROM、EEPROM和DRAM寄存器，以及模拟和数字接口。
B、主电源板：也称为主触发板，它包括数字输入输出继电器和接口，并连接到TCB板上，它控制旁路隔离接触器的动作顺序和SCR的触发，这个板子上产生全部触发信号和接收来自光纤隔离的反馈信号，把模拟信号转换为CPU的数字信号，这些触发脉冲也是利用光纤对中高压环境进行隔离。
C、电压、电子控制部分：中高压主电源应在TCB、触发驱动器和TEMP/CT控制板工作之前断开。
D、TCB（Terminal and ControlBoard）终端控制板是用户的接线板，为了满足UL标准，它位于中压部分，并没有实际和中压部分联结，只是和接触器的控制线圈有连接，这个板子上包括用户接线端子排、输出继电器（全部相同）输入和控制电源接线、并且包括时间继电器用于功率因数调整继电器和其它外部元件。
E、触发驱动板：位于SCR模块组件上面，这些板子和主电源板通过光纤进行通讯联系，通过脉冲变压器把触发脉冲信号进行放大来触发SCR，在每个SCR模块中每一对SCR使用一个触发驱动电路板。
F、TEMP/CT：温度控制板和电流互感器板子是装在SCR模块组件上，通过光纤把散热器温度和电流信号送到主电源板。
