Problems solved by technology

The disadvantage is that the shunt resistor is easy to short-circuit with other structural parts, causing the entire motor to fail to work normally.
Due to the high working speed of the motor, generally around 10000r / min, the centrifugal force generated at high speed is relatively large. At the same time, the space of the motor rotor is limited. Conventional resistors are installed in the high-speed rotating rotor. short circuit

Abstract

The invention belongs to the alternating-current generator structure design technical field and relates to an improved protection structure of a high-speed alternating-current generator rotation half-wave rectifier bridge. The protection structure is characterized in that a motor hollow shaft (4) is a step hollow shaft; and a wire-wound resistor assembly composed of an insulating frame (3) and three copper wire-wound resistors (8) is adopted. According to the protection structure of the high-speed alternating-current generator rotation half-wave rectifier bridge of the invention adopted, the firmness of the installation of shunt resistors can be increased, and short circuiting between the shunt resistors and other structural components can be avoided, and the reliability of the protection structure can be improved.

Description

technical field [0001] The invention belongs to the structural design technology of an alternator, and relates to the improvement of the protection structure of a rotating half-wave rectifier bridge of a high-speed alternator. Background technique [0002] The rotary half-wave rectifier bridge involved in the present invention is an integral part of a large-scale three-stage high-speed alternator, and the large-scale three-stage high-speed alternator includes a main generator, a main exciter, and an auxiliary exciter; the main generator, the main exciter The motor and the auxiliary exciter rotate coaxially and are integrated in one housing. The rotating half-wave rectifier bridge rectifies the three-phase output voltage of the armature rotor of the main exciter into DC, and then supplies it to the excitation winding of the main generator for excitation. In order to avoid damage to the rotating rectifier in the rotating half-wave rectifier bridge due to the large current cau...
