Design Structure

1. 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.
2. Thyristor-protecting parts: mainly include over-voltage snubber network composed of RC network and the voltage balance protecting network composed of voltage balancing units of the grid used.
3. 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.
4. Vacuum switch parts: After the starting is completed, three-phase vacuum bypass contactor closes automatically, and the motor is put into grid for operation. 
5. 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.
6. 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.

Technical Characteristics

1. Free of maintenance:Thyristor is an electric device without contacts. Different from other kinds of products that need frequent maintenance on liquid and parts etc., it turns the mechanical lift into the service life of electronic components, so it needs no maintenance after running for many years.
2. Easy installation and operation:CMV is a complete system for controlling and protecting the starting of motor. It can put into operation only with the power line and motor line connected. The whole system can be tested electrically under low voltage before operating with high voltage.
3. Backup:The starter comes equipped with a vacuum contactor which can be used to start the motor directly in the inside. If CMV fails, the vacuum contactor can be used to start the motor directly to ensure the continuity of the production.
4. High voltage thyristor is a component of major loop, equipped with voltage balancing protection system and over-voltage protection system.
5. CMV comes equipped with an electromagnetic blocking device for fear of entering the high voltage device in the electrified state.
6. Advanced optical fiber transmission technique realizes the triggering detection of high voltage thyristor and the isolation between LV control loops.
7. 32-bit ARM-core microcontroller is used to perform central control which is real-time and high efficient with , high reliability and excellent stability.
8. LCD/touch screen display system in both Chinese and English with human-friendly operation interface.
9. RS-485 communication port can be used to communicate with the upper computer or centralized control center.
10. Aging experiments are made on all circuit boards.
