Basic Overvie
When the engine starts, the soft start cabinet controls the generator voltage and current to gradually increase,
thereby reducing the starting current impact and avoiding excessive impact on the power grid and the motor itself.
The start cabinet can not only achieve soft start, but also soft stop. When the engine stops, the soft start cabinet controls
the generator voltage and current to gradually reduce, making the equipment stop process smoother.
The smooth operation of the switch is conducive to improving the quality of electricity and saving energy.
The customer used this soft start control panel on the flood control pump to improve the flood control capability.
It is a great honor that Guozhiyun has solved the problem of power being deeply troubled by floods for the customer.
This type of soft start control cabinet is not only used for flood drainage, but also for water supply,
sewage treatment, exhaust and other system control.
Advantages And Characteristics
Protecting the motor:
The soft starter reduces the current surge during motor start-up, reduces the impact and wear during start-up, thereby extending the motor's lifespan.
Protecting the power grid:
Soft starters reduce the surge current during grid start-up and lower the capacity burden on the grid.
Improve efficiency:
Soft starters control the changes in current and voltage during motor start-up, reducing energy loss and improving system efficiency.
Reduce maintenance:
Soft starters reduce the failure rate and maintenance workload during motor start-up, thereby lowering maintenance costs.
Multiple startup modes:
Soft starter provides multiple startup modes such as current limiting startup, voltage ramp startup, and jump startup to meet different load requirements.
Intelligent control:
The soft starter adopts digital control technology, which can automatically detect and adjust the starting parameters to achieve the best starting effect.
Working principle:
The soft start control cabinet improves the quality of electricity consumption by reducing the starting current
and avoiding the impact of excessive current on the power grid. When the motor starts, the soft starter slowly
adds current and voltage to the motor to avoid instantaneous high current impact
when the motor starts. Once the motor reaches its rated speed, the control cabinet will automatically
restore the current and voltage to normal operation.
Technical performance:
The power supply voltage of the soft start control cabinet is usually AC380V, 50Hzz, and the control object is not more than 320 kilowatts of
three-phase asynchronous motors. It can work reliably under the conditions of an altitude of no more than 1000 meters,
an ambient temperature of no more than 45℃, and no less than -30℃.
Control Panel Enclosure:
control panel enclosure is a protective housing for control panels.
It shields internal components like circuit boards and switches from dust, moisture, and physical damage.
Made of materials such as metal or plastic, it comes in various sizes and designs.
It also helps manage cable routing and provides a secure installation for control panel systems.

Application areas
• Working principle:
The soft start control cabinet improves the quality of electricity consumption by reducing the starting current and avoiding the impact of
excessive current on the power grid. When the motor starts, the soft starter slowly adds current and voltage to the motor to avoid

an ambient temperature of no more than 45℃, and no less than -30℃.
• Protection function:
The soft start control panel has an overload protection function, which detects the change of motor current at any time
to achieve overload protection. At the same time, it also has a phase loss protection function, which detects the change of
three-phase line current at any time and responds to phase loss protection. The overheat protection function is also one of its important features.
The temperature of the thyristor radiator is detected through the internal thermal relay.
Once the radiator temperature exceeds the allowable value, the thyristor is automatically shut down and an alarm signal is issued.
• Classification:
According to the voltage, it can be divided into low-voltage soft start cabinet and high-voltage soft start cabinet;
according to the load, it can be divided into fan soft start cabinet, water pump soft start cabinet, etc. According to different load control methods,
it can also be divided into one-to-one soft start cabinet, one-to-multiple soft start cabinet, one-use and one-standby soft start cabinet,
two-use and one-standby soft start cabinet, etc.
