Explanation of the core advantages of high-pressure solid-state soft start

Tenghui TGRJ high-voltage solid-state soft start core advantage description, high-voltage soft start cabinet in industrial motor control has significant advantages, the following is a detailed description of its core advantages (
1.& nbsp; Smooth start-up and shut-down to reduce mechanical shock
Slow start/stop:by gradually increasing the voltage or current, avoid the instantaneous impact when the motor starts at full voltage, and reduce the wear of mechanical parts such as gears, bearings, and belts.
Extend equipment life:reduce mechanical stress, extend the service life of motors and associated equipment (such as pumps, fans).

2.& nbsp; Suppress start-up current, protect grid
Reduce peak current: The starting current can be limited to 2-4 times the rated current (up to 6-10 times for direct starting) to avoid sudden drops in grid voltage.
High compatibility:suitable for scenarios with limited power grid capacity or strict requirements for voltage stability (such as Kuangqu and remote factory areas).

3.& nbsp; Intelligent control and regulation
Adjustable parameters:Users can customize parameters such as starting time and initial torque according to load characteristics (such as pumps and compressors).
Multiple control modes:support constant current, voltage ramp, jump start and other modes to adapt to complex operating conditions.

4.& nbsp; Multiple protection features for increased security
Fault protection:integrate overcurrent, overvoltage, undervoltage, phase loss, short circuit and other protection mechanisms to cut off faults in time.
Real-time monitoring:equipped with display screen or remote interface, real-time monitoring of current, voltage, power and other parameters, easy to fault diagnosis.

5.& nbsp; Energy saving and economic benefits
Reduce energy consumption:optimize the start-up process to reduce ineffective power consumption, long-term operation to save electricity bills.

Reduction of maintenance costs:Reduction of mechanical and electrical shocks reduces frequency of equipment maintenance and replacement costs of spare parts.

6.& nbsp; System compatibility and extensibility
Adapt to high voltage environment:Designed for 3kV~15kV power grid, meet the needs of large industrial equipment.
Integrated automation system: support linkage with PLC, DCS and other systems to achieve remote control and centralized management.

7.& nbsp; Reduced grid and transformer capacity requirements
Reduce grid load:Low start-up current reduces the demand for transformer capacity and reduces initial investment costs.
Avoid equipment expansion: itcan be applied under the existing power grid conditions, saving the cost of transformation.


typical application scenarios
Heavy equipment: such as mine crusher, large compressor, rolling mill, etc.
Fluid control: pumps, fans, etc. systems where water hammer/surge effects need to be avoided.
Continuous production line: such as chemical industry, cement industry, require smooth start to ensure production continuity.
