High pressure solid state soft starting device   RNMV-E

Key attributes

characteristic

With thyristor valve body as the main circuit component, it has the advantages of advanced technology, reliable operation, modular structure and maintenance-free.

The product has strong adaptability, and can work normally under the condition of isolated network or generator power supply at home and abroad;

It is based on 32-bit ARM core microcontroller to implement central control, which has fast response speed, high control precision and strong anti-interference ability Such advantages;

The cabinet body is made of KYN28 structure, beautiful appearance, and the material is made of aluminum-zinc coated plate, which is assembled by multiple bending. every The control operation is carried out when the cabinet door is closed;

High and low pressure separation,The cabinet consists of a low pressure chamber,hyperbaric chamber,Valve group chamber is composed of three parts,With five anti-blocking function;

The cabinet body is consistent with the standard switchgear, which can be conveniently combined with other high-voltage switchgear on site, so that the whole system is uniform in style

Soft - starting Functionality

• Gradual Acceleration: The RNMV - E provides a smooth and gradual start for high - pressure motors. Instead of applying full voltage immediately, it gradually increases the voltage and current supplied to the motor over a pre - set period. This reduces the inrush current, which can be up to 5 - 8 times the rated current in direct - on - line starting. By minimizing the inrush current, it protects the motor windings, reduces mechanical stress on the motor and the connected load (such as pumps, compressors, or conveyors), and extends the service life of the equipment.
• Adjustable Starting Parameters: Users can adjust various starting parameters according to the specific requirements of the motor and the load. Parameters such as starting time, current limit, and torque ramp - up can be customized. For example, in applications where a very slow and gentle start is needed to avoid water hammer in a pumping system, the starting time can be set to a longer duration, and the torque ramp - up can be adjusted to be more gradual.
