GE DS3800NHVN High Voltage Board

Part Number DS3800NHVN Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS3800NHVN 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.
