设计结构（Design structure）完整的CMV系列软起动装置是一个标准的电机起动、保护装置，用来控制和保护高压交流电机。标准的CMV产品主要由以下部件组成：高压可控硅模块、可控硅保护部件、光纤触发部件、真空开关部件、信号采集与保护部件、系统控制与显示部件。Complete CMV series soft starter is a standard device for starting and protecting motors, and can be used to control and protect high voltage AC motors. Standard CMV product is composed of the following parts: high voltage thyristor module, thyristor-protecting parts, optical fiber triggering parts, vacuum switch parts, signal acquiring and protecting parts, system controlling and displaying parts. u       可控硅模块：每相中采用相同参数的可控硅串并联安装在一起。根据所使用电网的峰值电压要求，选择可控硅串联的数量不同。u       Thyristor module: The thyristors of the same parameters are assembled in series-parallel in each phase. The number of the selected thyristors to be assembled in series is different, which depends on the peak voltage requirements of the grid used. u       可控硅保护部件：主要包括由RC网络组成的过电压吸收网络、由均压单元组成的均压保护网络。u       Thyristor-protecting parts: mainly include over-voltage snubber network composed of RC network and the voltage balance protecting network composed of voltage balancing units. u       光纤触发部件：采用强触发脉冲电路，保证触发的一致性和可靠性；利用光纤触发进行可靠高低压隔离。u       Optical fiber triggering parts: The consistency and reliability of triggering are ensured by strong triggering pulse circuit; optical fiber triggering is used for reliable separation of high voltage and low voltage. u       真空开关部件：在起动完成后，三相真空旁路接触器自动吸合，电动机投入电网运行。u       Vacuum switch parts: After the starting is completed, three-phase vacuum bypass contactor closes automatically, and the motor is put into grid for operation.  u       信号采集与保护部件：通过电压互感器、电流互感器、避雷器、零序电流互感器对主回路电压、电流信号进行采集，主CPU控制并进行相应保护。u       Signal acquiring and protecting parts: The acquisition of the voltage and current signals in the major loop, control of main CPU and corresponding protection are realized by voltage transformer, current transformer, arrester and zero sequence current transformer. u       系统控制与显示部件： 32位ARM核微控制器执行中心控制、LCD液晶\触摸屏显示，可显示三相电压、电流，故障信息、运行状态等。u       System controlling and displaying parts: 32-bit ARM-core microcontroller performs the central control. LCD/touch screen display can display three-phase voltage, current, fault information and running state etc.
