Problems solved by technology

The current loading system generally uses resistors as loads, only a few fixed power levels, and cannot be used for a variety of generators. The cooling uses blower air cooling. The entire loading system is bulky, noisy, and the life of the resistors used is not long. Also does not have a temperature alarm power-off control

Abstract

The airplane generator loading system provides an artificial load for testing airplane generator. In the process of testing the constant speed gear of airplane, integrated driving generator and generator, the most of testing items are completed in term of adding the load to generator. This invention comprises the controller, the powers classifying relay, the electric heater loading, the panel control and display, the temperature test and alarm, the cooling tank and scale removal unit, the generator, the upper controller. The invention is not identical with high power artificial loading system, it has the both auto loading and manual loading function, the load power resolution is 1kW, the resistive load power is tunable between 1-150kW. It also has 90kW ( power factor 0.75) and 150kW( power factor 0.6) inductive load. Meanwhile it has the advantage such as compactness, low noise, long life time and high reliability.

Description

Technical field [0001] The invention relates to an aircraft generator loading system which provides simulated loads for an aircraft constant speed transmission device, an integrated drive generator and a detection system of the generator. Background technique [0002] Aircraft constant speed transmission CSD (Constant Speed ​​Device) and generator, integrated drive generator IDG (Integrated Drive Generator) are the main components of the aircraft power supply system, providing 400Hz, 115V / 200V three-phase AC power for the aircraft instrumentation, radar , radio communications and various controls and lighting on the aircraft to provide power. According to aviation airworthiness standards, it should be maintained and repaired regularly and irregularly. As the detection system for the ground simulation test, according to the CSD / IDG detection standard, the various states of the CSD / IDG during the flight are simulated by the test bench to detect whether its performance indicat...
