Products Description
Soft starting device is the high voltage ac motor starting equipment, its main composition is connected
into the power between the charged with motor and three instead of parallel thyristor components and
electronic control unit. WSTRHV series high voltage solid-state soft starting device is composed of multiple
thyristor series parallel, by controlling the thyristor trigger Angle to control the size of the output voltage,
can satisfy the motor starting process in different voltage and current requirements. In the process of motor
starting, WSTRHV series high voltage solid soft starting device according to the preset curve starting, increase
the voltage of the motor, the motor smooth acceleration, so as to reduce motor starting on the grid, and
connected equipment electrical and mechanical shock. When the motor starts up to normal speed, the
bypass vacuum contactor or circuit breaker is connected, and the motor starts to finish. During the operation
of the motor, the soft starting device continues to monitor the motor, measuring the electric current, voltage
and all kinds of fault protection in real time.

Working principle
When the soft start device detects the external start command, after the microprocessor detects the synchronization signal, the
main circuit thyristor phase angle trigger control, and gradually increase the motor side of the current and voltage, so smooth
start the motor. In this process, the RC RC absorber absorbs the peak voltage at the time of thyristor reverse turn-off; the
voltage-controlled thyristor voltage ensures that each thyristor voltage in the series circuit is equal. Fiber triggering ensures
electrical isolation between the controller and the high voltage thyristor, while ensuring that the trigger signal is not subject
to electromagnetic interference.
Functioning
1. Protection function
the protection action and send a signal.
2) Over-current protection: start or run the process of excessive current, more than set the current value,
protection action and send a signal.
3) Current imbalance: three-phase current imbalance will lead to motor jitter and heat, three-phase current
unbalance value exceeds the set range, the protection action concurrent signal.
4) Start-up time: When the motor starts longer than the set time limit, the protection action is signaled.
5) Overload protection: motor running process, the occurrence of overload, the protection action and signal.
6) Underload protection: During operation of the motor, underload or loss occurs, protection action is generated.
1) Voltage measurement: measurement of power line voltage
2) Current measurement: motor A, B, C three-phase current detection.
1) Display communication: display panel selection touch screen, RS232 communication.
2) External communication: external device and controller communication, RS485 communication,
1) The amount of 8 points, optoelectronic isolation, no power into.
2) Out of 7 points, contact capacity of 10A / 250VAC, no power out.
1) Touch-screen display, a touch operation.
2) Transfer switch and operation button: straight up / soft start, the cabinet / remote two switch, start, stop,
direct start, emergency stop four buttons.
3) Status indicator: power, ready, start / soft stop, bypass / run, fault, bypass points 6 lights.
Note: The above is the standard configuration, special circumstances can be adjusted according to user needs.
