The invention relates to a novel high-voltage thyristor valve module. The novel high-voltage thyristor valve module is mainly composed of valve stack assemblies, a metal framework, reactor assemblies, a water-cooling system assembly, water resistor assemblies and damping capacitor assemblies. The valve stack assemblies, the reactor assemblies, the water-cooling system assembly, the water resistor assemblies and the damping capacitor assemblies are arranged in the metal framework. The reactor assemblies are arranged on the two sides in the metal framework. The water-cooling system assembly is arranged in the middle of the metal framework. The valve stack assemblies, the water resistor assemblies and the damping capacitor assemblies are respectively and symmetrically arranged on the two sides of the water-cooling system assembly. The novel high-voltage thyristor valve module is more compact in overall structural layout and more stable in structure by the adoption of symmetric arrangement.
