Problems solved by technology

[0002] The protective devices such as rotating rectifier diodes and RC absorbers used in existing synchronous generator exciters are respectively fixed on a mounting bracket by fastening methods such as screws, and the mounting bracket is then fixed on the rotor of the synchronous generator exciter. , due to the large volume and weight of the relevant components and many fixed points, under the condition of 3000 r / min or higher rotation speed, the shafting will bear a large centrifugal force, the vibration of the shafting is large, and the probability of failure is relatively high. Large, there is a high chance of damaging the rotor coil

Abstract

The invention provides a built-in resistance and capacitance protection type rotating rectifier assembly. The rotating rectifier assembly comprises a capacitor base. The negative electrode of a left rectifier diode is electrically connected with the positive electrode of a right rectifier diode and a conducting rod. The positive electrode of the left rectifier diode is electrically connected with a left conducting strip. The negative electrode of the left rectifier diode is electrically connected with the left conducting strip through a circuit in which a left capacitor and a left fusible resistance wire are serially connected. The negative electrode of the right rectifier diode is electrically connected with a right conducting strip. The positive electrode of the right rectifier diode is electrically connected with the right conducting strip through a circuit in which a right capacitor and a right fusible resistance wire are serially connected. The right capacitor and the left capacitor are fixed in the capacitor base. The objective of the invention is to provide a built-in resistance and capacitance protection type rotating rectifier assembly having advantages of small size, compact structure, good cooling performance, long service life, low failure occurrence rate, good reliability and convenient utilization.

Description

technical field [0001] The invention relates to a rotating rectifying assembly with built-in resistance-capacitance protection. Background technique [0002] The protective devices such as rotating rectifier diodes and RC absorbers used in existing synchronous generator exciters are respectively fixed on a mounting bracket by fastening methods such as screws, and the mounting bracket is then fixed on the rotor of the synchronous generator exciter. , due to the large volume and weight of related components and many fixed points, under the condition of 3000 rpm or higher rotation speed, the centrifugal force on the shafting of the power generation price is large, the vibration of the shafting is large, and the probability of failure is relatively high. Large, the probability of damaging the rotor coil is very high. Contents of the invention [0003] The object of the present invention is to provide a rotary rectifier assembly with small volume, compact structure, good heat ...
