Description

Technical Field

[0001] The utility model relates to the technical field of voltage regulators, in particular to a regulator for a generator. Background Art

[0002] The generator regulator is specially designed for AC brushless generators with fundamental wave, harmonic compound excitation or permanent magnet generator excitation. The voltage regulator automatically adjusts the generator output voltage by controlling the excitation current of the generator AC exciter. The generator regulator can meet the needs of ordinary 60 / 50Hz and medium frequency 400Hz single machine or parallel operation of generators.

[0003] In order to ensure the stability of the generator output voltage, the voltage regulator usually controls the bias of the transistor base according to the change of the corresponding load of the generator to achieve the change of the transistor conduction time, thereby changing the size of the generator excitation current to achieve the stability of the output voltage. The existing voltage regulators are basically in an exposed state and are easily hit by external objects, which may cause damage to the voltage regulator and shorten the service life of the voltage regulator.

[0004] A Chinese patent discloses "an automatic voltage regulator for a generator", and the publication number is CN214177195U. The automatic voltage regulator for the generator is fixed by a mounting frame, and the first rubber pad increases the stability of the voltage regulator when it is fixed, avoiding the problem of the voltage regulator loosening and falling off due to vibration. The voltage regulator is fixed by pushing the second rubber pad on one side of the card through the first compression spring and the second compression spring, and the inner shell is buffered and shock-absorbing by four groups of buffer springs, avoiding the problem of external force impact or vibration causing damage to the internal voltage regulator, while improving the stability of the inner shell.

[0005] The existing automatic voltage regulator for generators is fixed and protected by a mounting frame, fixed by a compression spring, and buffered and shock-absorbing by a buffer spring. However, when the mounting frame is hit by an external impact, the impact force causes the regulator to shift between the inner shell and the outer shell. Although the buffer spring can buffer the force on the regulator during the shifting process and reduce the shift amplitude of the regulator, the elastic force of the buffer spring and the compression spring will increase the vibration frequency of the regulator, making it impossible for the regulator to be stationary in time, and easily causing the wiring part of the regulator to loosen, affecting the normal operation of the regulator. In view of this, we propose a regulator for generators. Utility Model Content

[0006] The utility model aims to provide a regulator for a generator, which solves the problems raised in the above-mentioned background technology.

When the regulator body is offset by the impact, the horizontal force of the regulator body is offset by the spring, and the vertical downward pressure of the regulator body is offset by the elastic telescopic rod. When the regulator body is subjected to horizontal vibration due to the rebound force of the spring, the friction force between the positioning frame and the positioning rod is used as damping to absorb. When the regulator body is subjected to vertical vibration due to the rebound force of the elastic telescopic rod, the friction force between the slide plate and the rubber plate and the friction force between the regulator body and the rubber pad are used as damping to absorb, so that the regulator body can be quickly stationary to prevent the wiring from loosening.
