Problems solved by technology

[0002] The pressure-resistant machines produced by the company recently often have smoke from the meshing part of the reduction gear of the voltage regulator, which leads to the return of the voltage regulator to the factory. However, the same result still exists after returning to the factory. Such repetitions not only increase the work The quantity also greatly delays the delivery cycle of the equipment

Embodiment 1

[0023] In order to automatically adjust the output voltage of the voltage-resistant machine, a motor is arranged in the voltage-resistant machine so that the gear of the motor meshes with the gear of the voltage regulator. The gear of the voltage regulator in the pressure-resistant machine is driven to rotate by the motor, so that the voltage in the voltage regulator is automatically adjusted in an electric manner. Such as figure 1 As shown, the motor and the voltage regulator are connected by a fixed frame 4, and the motor casing 1 and the voltage regulator casing 5 are connected to the fixed frame 4 by bolts. The motor is provided with a pinion assembly 2, and the pinion assembly 2 includes a small gear and a small shaft; the voltage regulator is provided with a large gear assembly 3, and the large gear assembly 3 includes a large gear and a large shaft.

[0024] When the fixed frame 4 is an integral metal frame, the small gear assembly 2 on the motor in the pressure-resist...

Embodiment 2

[0028] Such as figure 2 As shown, the difference between the present embodiment and the first embodiment is that the fixing frame 4 is an integral metal frame and has not been cut off. However, at least one of the pinion gear and the small shaft in the pinion gear assembly 2 in this embodiment is made of an insulating material, and the insulating material used is preferably polytetrafluoroethylene, which is plastic king. When the pinion or the small rotating shaft is made of insulating polytetrafluoroethylene, the closed circuit mentioned in the first embodiment is blocked, and no induced current can be formed, so there will be no contact between the pinion and the bull gear. Generate smoke or sparks.

Abstract

According to an electric arc prevention method and an electric arc prevention structure of a voltage withstanding machine, a small gear assembly on a motor in the voltage withstanding machine, a motorshell, a fixing frame, a voltage regulator shell and a large gear assembly form a closed loop in sequence, and in order to avoid the situation that an induction current is generated in the closed loop when a voltage regulator in the voltage withstanding machine works, a structure for eliminating the induction current is arranged in the closed loop, so that an electric arc is prevented from beinggenerated between the small gear assembly and the large gear assembly. The structure for eliminating the induction current is arranged in the closed loop, so that the situations that smoke is generated at the meshing position of the reduction gears of the voltage regulator, and electric sparks are generated, are eliminated. According to the present invention, the potential safety hazards can be eliminated, the service lives of the voltage regulator, a motor and the like are prolonged, and the overall quality of the voltage-withstanding machine is improved.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to the improvement of pressure-resistant machines in rail vehicles. Background technique [0002] The pressure-resistant machines produced by the company recently often have smoke from the meshing part of the reduction gear of the voltage regulator, which leads to the return of the voltage regulator to the factory. However, the same result still exists after returning to the factory. Such repetitions not only increase the work The quantity also greatly delayed the delivery cycle of the equipment. [0003] After on-site test and analysis, the reason for the smoke from the meshing part of the reduction gear of the voltage regulator is the magnetic flux leakage of the voltage regulator itself. The field tests of Chint and Delixi’s voltage regulators are basically the same. Such problems will not occur if the original pressure regulating handle of the voltage regulator is used, but it is p...
