DS3800NHVN

DS3800NHVN is a High Voltage Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. In gas turbine control systems, a high-voltage board is a critical component responsible for managing the high-voltage power supply required for the ignition of the fuel-air mixture in the combustion chamber. The high-voltage board typically consists of a set of capacitors, transformers, and other electrical components that are used to generate and distribute the high-voltage electrical pulses required for the ignition process.

The high-voltage board is usually located near the ignition system and is connected to the gas turbine control system's main control board. When the gas turbine control system receives a signal to start the ignition process, it sends a command to the high-voltage board, which then initiates the process of charging the capacitors and generating the high-voltage pulses. It's important to note that the high-voltage board must be designed and built to withstand the harsh operating conditions of a gas turbine environment, including high temperatures, high pressures, and high levels of vibration. Additionally, the high-voltage board must be equipped with safety features such as overvoltage protection and grounding to ensure the safety of personnel and equipment.

FEATURES:

The high voltage board in gas turbine control systems typically has a number of important features, including:

High Voltage Pulse Generation: The board is designed to generate high voltage pulses, typically in the range of 15-25 kV, to ignite the fuel-air mixture in the combustion chamber.

Capacitor Charging Circuit: The high voltage board includes a charging circuit that charges the capacitors to the required voltage level before discharging them to generate the high voltage pulses.

Transformer and Coil Circuits: The board contains transformers and coil circuits that step up the voltage from the capacitor bank to the required ignition voltage.

Temperature and Vibration Resistance: The high voltage board must be designed to withstand the high temperatures and vibrations associated with gas turbine operation.

Reliability: The high-voltage board must be highly reliable and capable of operating continuously under harsh conditions.

Diagnostic and Monitoring Features: The high voltage board may include diagnostic and monitoring features to detect and diagnose any issues with the board, such as capacitance degradation, voltage drops, or other problems.
