Overview
AC squirrel cage asynchronous motor is the most widely used electrical equipment. The application of intelligent motor soft starter technology makes the starting equipment more consistent with the load characteristics, has less impact on the equipment grid, and has stable and reliable working performance. Series soft starters are widely used in motor transmission equipment in all fields such as metallurgy, chemical industry, construction, cement, mining, and environmental protection. It is an ideal replacement product for traditional star-delta starting, reactor starting, and auto-coupling step-down starting.
The soft starter takes an advanced microprocessor as the core and controls high-power thyristor components. It has current-limiting starting, voltage ramp starting, and soft parking functions. The parameters can be set according to the load, and it has over-current and short-circuit functions. , overload, phase loss and other protections. The soft starting device rises according to the set rule, so that the controlled motor torque completes the starting process according to the optimized acceleration curve, and then the bypass contact works to turn off the thyristor component.
Functions of series soft starters
Adopt dual single-chip fully automatic control
Starting torque current, voltage, and time can be flexibly set according to different loads to obtain the best current curve and the best Excellent torque control characteristics
Provide a smooth and gradual starting process for the motor, reduce the impact of the starting current on the power grid, reduce the vibration and noise of the equipment, and extend the service life of the mechanical transmission system
Starting current It can be adjusted according to the load to reduce the starting loss and produce the best torque with the minimum current
The soft stop feature greatly extends the life of the electrical contacts to meet the mechanical needs in different occasions
With overcurrent and overload capabilities , short circuit, overheating, power phase loss, output phase loss protection
Convenient external control interface has multiple functions: delayed start control, instantaneous stop control, start delay relay output, fault relay output
Right The input power supply has no phase sequence requirements
Comes with standard connections
Overvoltage protection When the control module detects that the grid voltage is higher than the set threshold, it will issue an overvoltage alarm and stop the motor.
The overvoltage alarm will automatically reset after the fault is eliminated.
, Under-voltage protection
When the control module detects that the grid voltage is lower than the set threshold, it issues an under-voltage alarm and stops the motor. The undervoltage alarm is automatically reset after the fault is eliminated.
, Phase loss protection
When the control module detects a phase loss in the power supply or motor coil, it will issue a phase loss alarm and stop the motor. The phase loss alarm is automatically reset after the fault is eliminated.
, Timeout protection
When the starting process exceeds the set time threshold, a timeout alarm is issued and the starting process is stopped. Timeout alarms require manual power off or reset on the control panel.
, Overcurrent protection
When the control module detects that the current is higher than the overcurrent limit, it issues an overcurrent alarm and stops the motor. The overcurrent limit (multiple of overcurrent and rated current) can be set on the panel. After the fault is eliminated, the overcurrent alarm needs to be manually powered off or reset on the control panel.
, Bypass fault protection
When the control module detects a bypass fault, it issues a bypass fault alarm and stops the motor. After the fault is eliminated, the bypass fault alarm needs to be manually powered off or reset on the control panel.
, Silicon fault protection
When the control module detects a silicon fault, it issues a silicon fault alarm and prohibits starting the motor. The silicon fault alarm is automatically reset after the fault is eliminated.
, Overload protection
The control module determines whether the soft starter and motor are overloaded according to the measured current, time and temperature and the preset protection characteristics, and issues an overload alarm and stops the starting or running of the motor. When the starter operates in bypass mode, an external current transformer is required to provide overload protection for the motor.
