GB/T 37405-2019
ActiveHigh voltage soft-start device by thyristor phase control
高压晶闸管相控调压软起动装置
Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for high-voltage thyristor phase-controlled soft-start devices used to control the starting current and torque of AC motors. It is applied in industrial settings such as mining, petrochemical, and water treatment, where large induction or synchronous motors require smooth, reduced-voltage starting to prevent mechanical stress and electrical grid disturbances.
