Technical Specifications Multi‑channel trigger signal input and isolated trigger output. Auxiliary power supplied by excitation rack, typical power consumption 7.1 W. Operating temperature ‑10 ℃ to +55 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated circuit board, isolation voltage 2500 V AC.
Functional Features Receives trigger pulse command from excitation regulator. Completes trigger signal shaping, isolation and distribution. Outputs driving signal for thyristor power components. On‑board LED indicates trigger channel status. Built‑in hardware self‑diagnosis for trigger circuit faults. Conformal coating provides moisture‑proof and dust‑proof protection.
Application Scenarios Key spare‑part for generator excitation systems in thermal power plants, hydropower stations and industrial self‑power plants. Used for equipment overhaul and spare‑part replacement.
Performance Parameters Accurate trigger‑pulse timing meets thyristor turn‑on requirement. High‑voltage isolation separates control circuit and power circuit. Self‑diagnosis rapidly detects trigger‑channel loss and circuit abnormality.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Pulse signal processing chips, high‑voltage optocoupler isolation assemblies. Conformal protective coating. Back‑plane plug‑in connectors and thyristor‑side trigger output terminals.
Structural Characteristics Standard plug‑in circuit board matching excitation cabinet slot. Board edge equipped with back‑plane bus connector and trigger‑signal output terminals. Reserved mechanical fixing holes.
Working Principle After power‑on, board completes hardware self‑check. Trigger pulse commands from main regulator board are received via back‑plane bus. Signals go through shaping and high‑voltage isolation processing. Processed trigger pulses are distributed to each thyristor unit. Diagnosis circuit monitors running state of each trigger channel continuously.
Installation Requirements Completely cut off excitation cabinet main power and control power before replacement. Insert XVC767AE102 into designated slot and tighten fixing screws. Ensure back‑plane connector is fully engaged. Restore power supply and complete excitation‑system trigger‑pulse function test.
Usage Notes Implement anti‑static protection during handling.
