Application Scenarios Applied for generator excitation system of power plant. Realizes generator excitation closed‑loop control. Used for equipment overhaul and spare‑part replacement.
Performance Parameters Regulation response speed satisfies generator excitation control requirement. Pulse output signal keeps stable. Self‑diagnosis can capture main circuit fault.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. High‑speed signal processing chip, pulse drive components. Screw‑type signal terminals. Metal fixing support. Multi‑pin plug‑in connectors.
Structural Characteristics Flat embedded circuit board structure. Signal terminals arranged on board edge, multi‑pin internal connectors. Board dimension matches excitation cabinet assembly space. Weight approximately 0.62 kilogram.
Working Principle After power‑on, board completes hardware self‑check. It receives generator voltage and current feedback signal together with excitation setting signal. Internal control unit calculates and outputs trigger pulse signal to power thyristor unit. Realizes generator excitation current closed‑loop adjustment. Fault feedback signal is collected and uploaded to upper system.
Installation Requirements Fix circuit board in excitation cabinet appointed position. Tighten fixing screws. Plug each internal connector in place. Complete external signal wiring strictly follow excitation system drawing. Ensure cabinet reliable protective grounding. Verify function after power‑on.
Usage Notes Wear anti‑static wrist strap in disassembly and assembly process. Cut off excitation system total power before operation. Do not touch high‑voltage circuit area on board. Periodically check terminal tightening status. Prevent dust accumulation on circuit board surface.
