Vehicle-mounted intermediate-frequency generator set

Abstract

Provided is a vehicle-mounted intermediate-frequency generator set. An intermediate-frequency brushless alternating-current generator is mounted on the end portion of a seam allowance flange plate of an air-cooled high-speed diesel engine through a flange plate. The air-cooled high-speed diesel engine is mounted on a generator set base and is in transmission connection with the intermediate-frequency brushless alternating-current generator through a spline flexible shaft. According to the vehicle-mounted intermediate-frequency generator set, the intermediate-frequency brushless alternating-current generator and the air-cooled high-speed diesel engine are assembled to form a whole so that a mechanical failure can be effectively avoided, the occupied area of the generator set is substantially reduced, and the size of the generator set is further reduced; a rotor of the intermediate-frequency brushless alternating-current generator is not provided with a winding and a rectifying element so that an electrical failure can be avoided; and an inverter is not needed for conversion and power supply, instead, the intermediate-frequency brushless alternating-current generator directly supplies power to the outside, and therefore high-quality power supply is guaranteed. The vehicle-mounted intermediate-frequency generator set is compact in structure, simple and convenient to operate, stable in performance, high in power supply quality, long in service life and suitable for all kinds of field engineering operation in various complex geographical environments with climate and temperature changes.

Description

technical field [0001] The invention relates to the power supply of an AC intermediate frequency generator set driven by a diesel engine, in particular to a vehicle-mounted integrated diesel AC intermediate frequency generator set. Background technique [0002] The three-phase AC intermediate frequency power supply was first used in the electrical facilities of aviation aircraft, and later it was widely used in military power supply systems. Now many special industries such as vehicle-mounted and field engineering operations also use a large number of intermediate frequency power supplies. [0003] The common features required by these special industries for intermediate frequency power supplies are: compact structure, light weight, and small volume; high reliability is required for field engineering operations; the scope of engineering operations is various complex geographical environments and changes in climate and temperature , in addition to requiring the quality of po...

AI Technical Summary

Problems solved by technology

Working in a harsh environment for a long time, the engine needs to provide greater required power, which will cause the engine to work in an unstable overload state for a long time, resulting in damage to the engine, mechanical interface, generator or parts, and frequent failures, making the system The overall reliability is greatly reduced, or even paralyzed, so that the overall life of the vehicle-mounted intermediate frequency generator set is greatly shortened.
