High Voltage Soft Grid-connected Device
Overview
CGC series high-voltage soft grid-connected device is soft grid-connected device designed for a high-voltage generator with a relatively new concept,
which is mainly suitable for the control and protection of the start and stop of the generator. This device adopts optical fiber isolation, dynamic and static
voltage equalization protection measures, and realizes the high-performance operation of the equipment. The device performs closed-loop control of
the SCR through the grid connection momentarily, and uses the grid reactive power to excite the generator. At the same time, a special algorithm for
soft grid connection is adopted, which reduces the power oscillation problem in the grid connection link.
The use of a soft grid-connected device can reduce the grid-connected impulse current of the motor and reduce the impact on the grid and the motor itself.
At the same time, it also reduces the impact on the mechanical equipment, so as to prolong the service life of the equipment and reduce the failure and downtime.
Features
1.The advanced optical fiber transmission technology realizes the isolation between the trigger detection of the high-voltage thyristor and the low-voltage control loop.
2.The CGC is equipped with an electromagnetic lock device to prevent it from entering the high-voltage device by mistake under the condition of electrification.
3.Advanced control algorithm reduces current impact and power shock during grid connection.
4.Chinese and English LCD display system, user-friendly operation interface
5.Built-in vacuum contactor, which can directly start the motor
6.High-voltage thyristor is the main circuit component, and has voltage equalization protection and overvoltage protection systems.
