VW3A4408软启动器施耐德中文说明书

VW3A4408电机软启动器(软起动器)是一种集电机软起动、软停车、轻载节能和多种保护功能于一体的新颖电机控制装置，国外称为Soft Starter。

VW3A4408软启器采用三相反并联晶闸管作为调压器，将其接入电源和电动机定子之间。这种电路如三相全控桥式整流电路。

VW3A4408使用软启动器启动电动机时，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，实现平滑启动，降低启动电流，避免启动过流跳闸。

VW3A4408待电机达到额定转数时，启动过程结束，软启动器自动用旁路接触器取代已完成任务的晶闸管，为电动机正常运转提供额 定电压，以降低晶闸管的热损耗，延长软启动器的使用寿命，提高其工作效率，又使电网避免了谐波污染。

VW3A4408软启动器同时还提供软停车功能，软停车与软启动过程相反，电压逐渐降低，转数逐渐下降到零，避免自由停车引起的转矩冲击。

VW3A4408 The motor soft starter (soft starter) is a novel motor control device that integrates motor soft starting, soft parking, light load energy saving and multiple protection functions. It is called Soft Starter abroad.

VW3A4408 The soft starter uses three opposite parallel thyristors as a voltage regulator, which is connected between the power supply and the motor stator. This kind of circuit is like a three-phase fully controlled bridge rectifier circuit.

VW3A4408 When a soft starter is used to start a motor, the output voltage of the thyristor gradually increases and the motor gradually accelerates until the thyristor is fully conductive and the motor operates at the mechanical characteristics of the rated voltage to achieve smooth start, reduce the starting current and avoid starting overcurrent tripping.

VW3A4408 When the motor reaches the rated revolution, the starting process ends, and the soft starter automatically replaces the thyristor that has completed the task with a bypass contactor to provide the rated voltage for the normal operation of the motor, thereby reducing the heat loss of the thyristor and extending the service life of the soft starter. , improve its working efficiency, and prevent the power grid from harmonic pollution.

VW3A4408 The soft starter also provides a soft stop function. The soft stop process is opposite to the soft start process. The voltage gradually decreases and the number of revolutions gradually drops to zero to avoid the torque impact caused by free stop.
