The invention provides a high-
voltage direct-current energy release device. The high-
voltage direct-current energy release device comprises a
lightning arrester body, a trigger switch
assembly, a resistance
tower assembly, an electric reactor
assembly, a bypass switch assembly and a base assembly, wherein the
lightning arrester body, the trigger switch assembly and the resistance
tower assembly are all of a vertical structure, and the
lightning arrester body and the resistance
tower assembly are arranged in a layered mode. The
lightning arrester body is arranged on the upper portion of the base assembly, the resistance tower assembly is located on the upper portion of the trigger switch assembly, the
lightning arrester body is connected with the trigger switch assembly and the resistance tower assembly in a layered mode, and the electric reactor assembly and the bypass switch assembly are both connected with the trigger switch assembly. The device is low in manufacturing difficulty, low in cost, simple in control process, relatively compact in arrangement, convenient for
optical fiber cable arrangement, small in occupied area, good in overall anti-seismic property, convenient to overhaul and maintain and relatively high in operation reliability, and the whole device is arranged in a layered and sub-functional area manner.
