Abstract

The invention discloses an aircraft distribution line fault protection jump switch test system. The aircraft distribution line fault protection jump switch test system includes a test power supply device, a load control device, a to-be-tested object parameter acquiring device, and a parameter comparison and analysis device which are arranged in a test cabinet and are connected to an electric line.The beneficial effects of the invention are that: protective performance parameters of an aircraft jump switch is tested on a wing without breaking an original structure of an aircraft distribution line and without demounting parts of the aircraft during an aircraft distribution line fault isolation process or an aircraft line regular maintenance period, determination of an aircraft jump switch malfunction and a real line fault can be achieved quickly and accurately, the reliability of ground maintenance fault positioning of the aircraft distribution line is ensured, and the maintenance efficiency is greatly improved; the test system has sufficient test capacity, loading test of all the data can be successively completed by one-time wiring, and the human cost and time cost can be saved greatly; and the test system has a long service life and upgrading space, and a new module can be added into the test system to achieve a new test function as needed in the future.

Description

technical field [0001] The invention relates to the field of fault diagnosis of aircraft power distribution lines, in particular to a test system for the performance parameters of the fault protection trip switch of aircraft power distribution lines. Background technique [0002] The aircraft power distribution system is the part from the power bus bar to the input of the electrical equipment. The power distribution system of the aircraft is composed of the grid power distribution device and the grid protection device. Its function is to transmit and distribute the electrical energy generated by the power supply to the electrical equipment of the aircraft. With the continuous improvement of aircraft performance, there are more and more on-board electrical equipment, and on-board electrical equipment plays a key or important role in the safe flight of the aircraft and the successful execution of tasks, so the reliability of aircraft power distribution lines, Security requir...
