Embodiment Construction

[0023] figure 1 The generator durability test bench shown includes: programmable controller 1 (Programmable Logical Controller, PLC), frequency converter 2, frequency conversion motor 3, cable 4, belt 5, workbench 6, fixture 7, AC load (not shown in the figure) ). The generator 20 is connected with an AC load, and is fixed on the workbench 6 through the clamp 7 . The programmable controller 1, the frequency converter 2, and the variable frequency motor 3 are sequentially connected through the cable 4, and the frequency conversion motor 3 drives the generator 20 to run through the belt 5.

[0024] Such as figure 1 As shown, the programmable controller 1 and the frequency converter 2 are placed in a control cabinet 9 on which a control panel 10 is arranged. By operating the buttons on the control panel 10, relevant test parameters such as the frequency of the frequency converter 2 and the start and stop times can be set. The frequency and start and stop time of the inverter ...

Abstract

The invention discloses a test bench for the durability of generators, which comprises a variable-frequency motor, a worktable and a fixture, wherein the fixture fixes a generator on the worktable; the generator is connected with an alternative current load and is operated by the variable-frequency motor via a belt. The test bench further comprises a programmable controller and a frequency converter, wherein the programmable controller, the frequency converter and the variable-frequency motor are connected via cables in turn; the frequency converter outputs the drive voltage needed by the variable-frequency motor, according to the frequency, start time and stop time set by the programmable controller. The test bench for the durability of generators has compact structure, low cost, high precision, automatic controlled test process and the application for middle and small laboratories.

Description

technical field [0001] The invention relates to a test device for an automobile alternator, in particular to a generator durability test stand. Background technique [0002] The alternator is an important part of the car. Its function is to supply power to all electrical equipment (except the starter) and charge the battery at the same time when the engine is running normally. Automobile generators can be divided into DC generators and AC generators. Since the performance of AC generators is superior to that of DC generators in many aspects, DC generators have been eliminated. At present, automobiles use a three-phase alternator with a diode rectifier circuit inside to rectify the alternating current into direct current, so the output of the automobile alternator is direct current. The alternator must be equipped with a voltage regulator, and the voltage regulator controls the output voltage of the generator to keep it basically constant to meet the needs of vehicle electri...
