Description

Technical Field

[0001] The utility model relates to the technical field of circuit components, in particular to a rotating rectifier component with resistance and capacitance protection. Background Art

[0002] The main function of the exciter is to provide the excitation current required by the generator so that the generator can generate electrical energy. When the exciter applies a certain excitation current to the generator, the rotating parts inside the generator will start to operate, so electrical energy will also be generated. The synchronous generator exciter uses rotating rectifier diodes and RC and other protective devices. The diodes and conductive rods in the equipment need to be electrically connected, so the conductive rod plays a vital role in the equipment.

[0003] However, in the existing equipment, the conductive rods are fixedly connected to the base of the capacitor by screws. When they need to be replaced later, the screws need to be removed before they can be removed. This installation method is not convenient to disassemble, which increases the difficulty of subsequent maintenance. Therefore, a rotating rectifier component with built-in resistance-capacitance protection is proposed. Utility Model Content
