Product Structure
Online soft start cabinet has intelligent control functions, supports multiple communication interfaces (such as RS485, Modbus, etc.), can be easily connected with PLC, DCS and other control systems to achieve remote monitoring and control. Users can real-time monitor motor operation parameters and status through upper computer, perform remote operation and fault diagnosis, improving the system's automation level and management efficiency.
- Reduce impact current: Online soft start cabinet can make the motor current rise with a smooth curve during startup, avoiding the impact current up to several times or even more than ten times the rated current produced by traditional startup methods (such as direct startup). This not only reduces the impact on the power grid, reduces voltage drop caused by excessive startup current, protects the normal operation of other equipment under the same power grid, but also extends the service life of motors and related equipment.
- Reduce mechanical stress: During startup, the soft start cabinet can gradually increase the motor's torque, avoiding mechanical impact caused by the motor instantly bearing excessive torque under traditional startup methods, reducing wear of transmission systems (such as belts, gears, etc.), reducing equipment maintenance and component replacement costs, improving equipment reliability and stability.
- Precise control: With multiple startup modes, such as voltage ramp startup, current limit startup, etc., users can flexibly choose according to different load characteristics and working condition requirements. At the same time, the soft start cabinet can precisely adjust startup time, current limit multiple and other parameters to achieve precise control of the motor startup process
- Soft stop function: In addition to soft start, online soft start cabinet also has soft stop function. It can make the motor gradually reduce speed during stopping, avoiding water hammer effect (for fluid loads such as water pumps) or mechanical impact caused by the motor suddenly stopping under traditional stopping methods, protecting equipment and pipeline systems, extending equipment service life.
Core Advantages of Online Soft Start Cabinet
Smooth Start, Reduce Impact
Traditional startup methods will generate large current impact, similar to the damage to the engine caused by sudden acceleration of a car. The online soft start cabinet allows the motor to start smoothly, greatly reducing the current impact on the motor and related equipment during startup, effectively extending the service life of the motor and equipment, and reducing maintenance costs.
Intelligent Control, Precise Adjustment
Built-in advanced intelligent control system, which can precisely adjust startup parameters according to different motor characteristics and load conditions. Whether it is a light-load startup small equipment or a heavy-load startup large machinery, it can find the most suitable startup mode to achieve efficient operation.
Energy Saving and High Efficiency, Reduce Costs
Optimize current during startup to reduce unnecessary energy consumption. Compared with traditional startup methods, the energy saving effect is significant. Long-term use can save a lot of electricity expenses for enterprises and improve economic benefits.
Adapt to Complex Working Conditions, Strong Stability
It has excellent environmental adaptability, and can operate stably in harsh environments such as high temperature, humidity, and high altitude. It provides continuous and reliable power support for industrial production, ensuring production continuity.
Complete Protection Functions, Safe and Reliable
Equipped with multiple protection functions such as overcurrent, overload, phase loss, undervoltage, etc. Once an abnormality is detected, it quickly takes protective measures to avoid damage to the motor and equipment, and保驾护航 for production safety.
Application Fields
- Industrial Manufacturing: Widely used in the motor startup control of various industrial equipment such as fans, pumps, compressors, mixers, conveyor belts. In chemical, steel, cement, paper and other industries, intelligent online soft start cabinets can effectively cope with complex load conditions, ensuring stable operation of production equipment.
- Construction Field: Used for motor startup of building water supply and drainage systems, ventilation and air conditioning systems, elevators and other equipment. Its low current startup characteristic can reduce the impact on the building power grid, ensure the stability of power supply, and reduce equipment maintenance costs.
- Municipal Engineering: In municipal facilities such as urban sewage treatment plants, waterworks, pumping stations, intelligent online soft start cabinets can realize smooth startup of large water pump motors, improve the operational reliability and efficiency of municipal facilities, and ensure the normal operation of the city.
- Mining Industry: Suitable for the startup of mining equipment, ventilation equipment, hoisting equipment and other motors. Facing the harsh working environment and heavy load startup requirements of mines, the protection functions and precise control capabilities of soft start cabinets play an important role, improving the safety and operational stability of mining equipment.
