Noker 3kV 6kV 10kV High Voltage Thyristor Motor Soft Starter Drives Assemble

Short Description:

High voltage motor soft starter assemble is designed with up-to date concept, mainly applicable to the control of and protection for the starting and stopping of squirrel-cage type asynchronous and synchronous motors. The starter is composed of several thyristors in series-parallel, and it can meet different current and voltage requirements.

High voltage motor soft starter is widely used in electric industry with rated voltage 3000 to 10000V, building materials chemical industry,metallurgy, steel and paper-making industries etc., and can perform well if used together with various kinds ofelectromechanical devices including water pumps, fans, compressors, crashers, agitators and conveyer belt etc., It is the ideal device for starting and protecting high voltage motors.

Protection function
Phase lose protection	If any phase of the input three-phase power supply is missing, the system will alarm and stop.
Over-current protection	During bypass operation, if the measured operating current exceeds the overcurrent setting value, the system will trigger alarm and stop within the set period.
Module overheating	The system will trigger alarm and stop if the temperature of the driving modules is greater than 85 degree as detected by the fiber optic.
Start-up timeout	During the motor start-up process, if the motor fails to accelerate to full speed within the start-up timeout limit, the system will trigger alarm and stop.
Unbalanced current	If the motor imbalance current exceeds the set value, the system will trigger alarm and stip within the set period.
Overload protection	When the operating current reaches the level set for overload protection, the system will trigger alarm and stop.
Over-voltage protection	If the detected grid voltage of the input three-phase power supply exceeds the overvoltage protection set value, the system will trigger alarm and stop within the set period.
Under-voltage protection	If the input three phase power supply's grid voltage falls below the underoltage protection set value, the system will trigger alarm and stop within the set period.
Short circuit protection	If the measured current exceeds the set value of short circuit overcurrent, the system will trigger alarm and stop within the set period.
Output phase loss protection	If there is a phase loss at the output end connected to the motor, the system will trigger alarm and stop.
Leakage protection	If the zero-sequence current exceeds the set value, the system will trigger the alarm and stop within the set period.
Over frequency protection	When the start-up frequency eceeds the set time limit within a short period.
Communication
Protocol	Modbus RTU
Interface	RS485
