Description

An aviation DC distribution relay

technical field

The invention relates to the field of aviation power distribution equipment, in particular to an aviation DC power distribution relay.

Background technique

The normal power supply of the aircraft is provided by the generator driven by the engine. When the output of the generator cannot meet the load demand, the auxiliary power supply of the aircraft battery is required to meet the needs of the electrical equipment, such as the engine starter, the hydraulic pump for retracting and retracting the landing gear, and the retracting and retracting flaps. When large loads such as motors and landing lights are started, when they are superimposed, or when a large load works for a long time, due to the limitation of battery capacity, the generator voltage regulator automatically cuts off the output of the left and right generators. At this time, the battery supplies power independently, and the voltage is rapid. decline. As the grid voltage drops, the current becomes smaller, the magnetic flux cannot reach the restoring force of the spring, the contacts of the relay are separated, the circuit will be disconnected, and the whole machine will be powered off, especially for small general aviation aircraft. After that, all electrical equipment on the aircraft will stop working, and the aircraft will lose functions such as communication, navigation, lighting, environmental control, and auxiliary power operation. The subsequent flight of the aircraft can only be completed by the pilot’s personal experience and ability; Supply fuel and the engine will be starved with the fuel pump stalled, which will be catastrophic.

In the prior art, there is no corresponding device structure to effectively solve the problem of contact separation of the relay when the magnetic flux decreases. When the problem occurs, the voltage is usually artificially increased to keep the current large enough, and the magnetic flux can effectively resist the The restoring force of the spring, and when the aircraft is flying in the air, no mistakes are allowed to ensure the safety of the whole aircraft. At present, it is not stable to control the closing of the relay simply by increasing the voltage. How can the relay be stably connected? In the closed state, it has become an urgent problem to be solved in the field of aviation power distribution equipment to avoid the flight failure caused by the disconnection of the relay during the flight.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the limitation of battery capacity in the aircraft power supply in the prior art. When the battery is independently powered, the voltage will drop rapidly and the current will become smaller due to the starting voltage division of the starter and other equipment, resulting in a decrease in the magnetic flux. The magnetic force cannot resist the restoring force of the spring, the relay contacts are separated, and the circuit will be disconnected.
