PST210-600-70 智能型软起动器

PST210-600-70指的是ABB公司的一款软启动器型号。ABB的PST系列软启动器结合了行业应用的丰富经验及对特殊应用需求的深刻了解，在多年产品研究和发展的基础上推出，是一款全新全智型电动机控制与保护产品。

具体来说，PST210-600-70软启动器采用三相反并联晶闸管作为调压器，通过三相全控桥式整流电路，实现电动机的平滑启动。在启动过程中，晶闸管的输出电压逐渐增加，电动机逐渐加速，直到晶闸管全导通，电动机工作在额定电压的机械特性上。这种启动方式可以降低启动电流，避免启动过流跳闸，并可根据需要调节启动电流的大小。同时，电机启动的全过程都不存在冲击转矩，实现了平滑的启动运行。

总的来说，PST210-600-70软启动器为工业领域的电动机提供了可靠且高效的启动解决方案。然而，具体的产品特性和使用条件可能需要根据ABB的官方资料或咨询专业工程师来获取。

The PST210-600-70 refers to a soft starter model from ABB. ABB’s PST series soft starter combines rich experience in industry applications and deep understanding of special application needs, based on years of product research and development, is a new all-intelligent motor control and protection product.

Specifically, the PST210-600-70 soft starter uses three opposite shunt thyristors as voltage regulator, and realizes the smooth start of the motor through the three-phase fully controlled bridge rectifier circuit. During the start-up process, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully switched on and the motor works at the mechanical characteristics of the rated voltage. This starting mode can reduce the starting current, avoid starting overcurrent trip, and can adjust the size of the starting current according to the need. At the same time, there is no impact torque in the whole process of motor start-up, and smooth start-up operation is realized.

Overall, the PST210-600-70 soft starter provides a reliable and efficient starting solution for electric motors in the industrial sector. However, specific product features and conditions of use may need to be obtained according to ABB’s official information or in consultation with a professional engineer.
