216EA61B HESG448230R1/G HVDC converter module is an important part of the power system, especially in the UHVDC transmission technology (HVDC), it plays the role of the core equipment. Here are some key information about the HVDC converter module:
Main components:
Thyristor stage: This is one of the main parts of the UHV DC converter valve module and consists of multiple thyristors or diodes to control the on-off and off-off of the current.
Saturation reactor: Its function is to inhibit the rate of change of the current flowing through the thyristor, limit the voltage generated by the thyristor, and improve the uniformity of the voltage distribution of the thyristor converter valve.
Resistive-capacitance voltage equalizing circuit (for series IGBT high voltage DC converter valve) : similar to the role of saturated reactor, used to suppress the change rate of the voltage at both ends of the IGBT, improve the uniformity of the distributed voltage of the IGBT converter valve.
How it works:
The 216EA61B HESG448230R1/G input is usually a three-phase AC power supply, which is converted from AC to DC by a bridge rectifier (consisting of a thyristor or diode).
To reduce the pulsating component of the DC voltage, filters are usually added to the DC circuit, consisting of capacitors and inductors, to help smooth the DC voltage.
Application scenario:
Uhvdc transmission: 216EA61B HESG448230R1/G is ideal for long-distance, large-capacity power transmission, especially for submarine cables and long-distance transmission. The HVDC converter module reduces transmission losses and power transmission losses in long-distance transmission by converting alternating current to direct current.
