Abstract

The invention discloses a reverse charging resisting device for an aircraft ground starting power supply. The reverse charging resisting device consists of an aerospace ground power supply, a reverse charge resisting device and an aircraft, wherein the reverse charge resisting device consists of a spiral diode, an aircraft end connecting device, a ground power supply end connecting device and a radiator. The reverse charging resisting device has the beneficial effects that 1, the reverse charging resisting device is small in size, simple in structure, and convenient to detach and maintain; 2, no movable electric contact component is adopted, so that the working reliability of a system is enhanced greatly, the service life of the system is prolonged greatly, the service lives of an airborne generator and an airborne storage battery are prolonged, and the flight safety is ensured at the same time; and 3, damage to the airborne generator caused by a voltage difference during startup operation of the aircraft is avoided, the defects of high cost, low reliability and short service life in an original differential under-voltage relay are overcome, and the reverse charging resisting device is mainly applied to charging operations of large-sized aircrafts. Through adoption of the reverse charging resisting device, the equipment cost of the aircraft ground starting power supply is reduced greatly. The reverse charging resisting device is suitable for starting and ground power-on checking operations of various helicopters and small and medium-sized fixed wing aircrafts.

Description

technical field [0001] The invention belongs to the technical field of aircraft ground power supply equipment. Specifically, it is an anti-reverse charging device for starting the power supply of the aircraft on the ground. Background technique [0002] When the aircraft is started on the ground and powered on for inspection, the onboard battery is expensive to use and has a limited lifespan. Generally, an external ground power supply is used for operations. Existing aviation ground starter vehicles are often lower than the rated voltage when the aircraft is started, so that there is a voltage difference between it and the aircraft generator, and the voltage of the aircraft generator is lower than that of the aircraft generator. The transformation of the aviation ground power supply into the load of the on-board generator will cause the on-board generator to overload, cause damage to the on-board generator, and also bring great hidden dangers to flight safety. The way to s...
