Abstract

The invention relates to the field of aircraft power supply system design, and relates to a helicopter non-emergency load unloading system and an unloading method thereof. Helicopter non-emergency load unloading system includes: unloading contactor, used to control the on-off between the main bus bar and non-emergency bus bar; generator contactor, used to output whether the generator is connected to the grid signal; ground power relay, used for When the ground power supply is turned on, it controls the unloading contactor to be connected; the non-emergency bus switch is used to control the status of the unloading contactor when the ground power supply is disconnected. The non-emergency bus switch includes "on" and "normal". and "unloading" three positions, and control the on and off of the unloading contactor according to different positions. In the helicopter non-emergency load unloading system and its unloading method of the present invention, the bus bar can be automatically unloaded first, and when the automatic unloading fails, the bus bar power supply switch can be used for manual unloading, which reduces the burden on the pilot and increases the emergency power supply time.

Description

technical field [0001] The invention relates to the field of aircraft power supply system design, and relates to a helicopter non-emergency load unloading system and an unloading method thereof. Background technique [0002] Helicopter electrical loads can be divided into two categories, one that affects flight safety, called emergency loads, and one that does not affect flight safety, called non-emergency loads. When the main power supply of the helicopter fails and the emergency power supply supplies power, in order to prolong the emergency power supply time, the non-emergency load should be disconnected immediately. [0003] At present, there are mainly two unloading modes for non-emergency loads: [0004] 1) Manual load unloading: when the emergency power supply is powered, the driver needs to disconnect the non-emergency load switches in turn, which is a heavy burden on the driver; [0005] 2) Manual unloading of bus bars: This unloading mode requires that all non-eme...
