3.good value
HGQ Series of High Voltage Solid State Soft Starter
Application
It applicable for three phase current 3KV,6KV,10KV,15KV of cage type asynchronous and synchronous motor soft start and protection.
Working Principle
Adopt three pair of antiparallel thyristor connected in series into between three phase voltage and ac motor input terminal. Meanwhile through adjusting three standalone antiparallel thyristor module of delayed conduction angle to change the ac input voltage amplitude of motor while to change three-phase input ac current effective value reached constant current starting or by a certain slope curve to achieve starting or stopping purpose. After finishing starting , three-phase bypass contactor can be automatic actuation and motor put into power system operation.
Performance and Features
1. Use high voltage power thyristor,assembled structure,modular design to convinent installation and maintain;
2. It has multiple overvoltage absorption and protection technology;
3. Start mode: on the basis of load features to choose to different starting model and parameters, in order to achieve in the best starting result of motor;
4. High technical characteristic: control circuit used high-performance microprocessors, ensure fast reliability for working;
5. High reliability: master control board goes by 72 hours high temperature loop around test and vibration test to assure the equipment reliable when it leaving factory;
6. Function of keyboard setting: convinent and fast operation display keyboard is as per the parameters, e.g. different load, to start, stopping, running and protection, etc. to set and modify;
7. Protective function: soft starter for motor starting process has protective function as phase lack, overload, over-current and starting time overrun,etc.
8. Rated output current (power Settings): when soft starter nominal power is bigger than the actual load power, can within the certain scope to modify soft starter's actual output current, to match it and actual load current, in order to ensure its output power and the actual load power matched with together.
