CMV high-voltage soft-start device is used for starting, controlling, protecting and soft-stopping high-voltage squirrel-cage AC motors. It is a new type of intelligent equipment with high performance, multi-function and high safety.
✔ 32-bit ARM core microprocessor, optical fiber drive, multiple dynamic and static voltage equalization protection;
✔ Reduce the starting impulse current of the motor and reduce the impact on the power grid and the motor itself;
✔ Reduce the impact on mechanical equipment, prolong its service life, reduce failures and downtime.
★ CMV-S's manifolds module is not fixed and can be withdrawn.
CMV-S_Detachable manifolds
AC 3 ~ 10 kV
3-Phase High Voltage Squirrel-Cage Asynchronous and Synchronous Motors
400 ~ 14000 kW
Suitable for water pumps, fans, compressors, pulverizers, mixers, belt conveyors and other mechanical and electrical equipment.
The manifolds is installed in the withdrawable KYN28 central high-voltage cabinet, and the thyristor valve body adopts the trolley installation method, which is convenient for users to check, test and maintain.
The cabinet is the same as the standard switch, which can be easily combined with other high-voltage switch cabinets on site, so that the style of the whole system is unified.
Protection class: IP40.
★ The manifolds module is not fixed and can be withdrawn.
