Embodiment Construction

[0020] A testing device 1 to be used for the method according to the invention is shown in FIG. 1 . The test device 1 is particularly suitable for verifying that the correct voltage and the correct phase difference are applied to the input terminals of a 3-phase AC motor mounted on board an aircraft. Furthermore, the test device 1 is capable of simulating the activation of thermal cutouts typically housed in 3-phase AC motors to prevent overheating of the motor windings, thereby minimizing the risk of fire on board the aircraft.

[0021] The testing device 1 is shown in perspective in FIG. 1 . The front panel of the testing device 1 comprises three LEDs L1, L2, L3. If the correct voltage is applied to the input terminal 24 on the rear side of the test device 1 (see FIG. 2 ), the three LEDs L1, L2, L3 are activated. If the same voltage is to be applied to the input terminals of a 3-phase AC motor installed on an aircraft machine, and the 3-phase AC motor will not exhibit any ...

Abstract

The invention discloses a testing method of power line and data line on the aircraft, wherein the power line and signal line are to connect 3-way AC motor and power system of aircraft; the 3-way AC motor has separated input terminal; the preset voltage with preset phase difference is exerted on the separated input terminal when the 3-way AC motor on the aircraft lies in the working period. The testing method comprises the following steps: connecting power line and signal line and input terminal (24) of test equipment (1) to replace 3-way AC motor; supplying voltage on the power line and signal line; judging whether the voltage of power line and signal line and phase different of voltage equals preset voltage and preset phase difference; testing the voltage through test equipment (1); proceeding phase test with voltage test synchronously. The invention also contains a test equipment (1) and kit tool of multiple adapters (5).

Description

technical field [0001] The present invention relates to a method and a kit for testing onboard power and signal lines of an aircraft. The power and signal wires are typically used to connect the aircraft's 3-phase AC motors to the power system. Background technique [0002] Modern aircraft house multiple 3-phase AC motors on board, which are used to provide power to various on-board facilities of the aircraft, such as air-conditioning systems located in different parts of the passenger cabin, cockpit, lavatory, cargo hold, or in other areas of the aircraft Fan or ventilator. Ventilators are typically powered by 3-phase AC motors. A thermal cutout is housed inside the 3-phase AC motor, which ensures that the 3-phase AC motor is automatically switched off, eg if the motor windings overheat. [0003] It is important that these 3-phase motors work correctly, turn in the correct direction, and that their safety devices and protections work correctly as designed. Therefore, du...
