Embodiment Construction

[0054] Aspects of the present disclosure relate to a power distribution system having a snubber board, particularly for a commercial aircraft. For purposes of illustration, the present disclosure will be described with respect to an aircraft power distribution system. However, it is to be understood that the present disclosure is not so limited, and may have general applicability in non-aircraft applications, such as in other power distribution applications.

[0055] By convention, circuit breakers for power distribution units are securely mounted to door panels through door panel cutouts. Wire the circuit breaker on the inside of the door panel, where the bus bars are assembled to complete the assembly. Next assemble the breaker fuse from behind the door panel, with the neck catching the breaker protruding from the back of the door to the front. A retaining nut is then fitted onto this section from the front, clamping the breaker to the door. A circuit breaker fuse can ind...

Abstract

The invention provides a power distribution system unit (14) and a method for managing a circuit breaker (50). The power distribution system unit (14) can comprise a housing (20) and a door assembly.The housing (20) has an inner bus structure (22). The door assembly (32) comprises at least one plug (54) which is accommodated in a socket (28). A buffer board (60) is fixed in the plug (28) and comprises a hole (62). Through the hhole (62), the plug (54) can be accommodated.

Description

technical field [0001] The present application relates to power distribution systems, and more particularly to power distribution systems and methods of managing circuit breakers therein. Background technique [0002] Commercial aircraft typically include power distribution systems. The purpose of the power distribution system is to distribute electricity to the loads on the aircraft, protect the lines and loads from hazards, and deliver the most appropriate power to each load. Power distribution systems can include power management panels that are used to route power from sources to wherever electrical loads are required. The power management panel may include a panel door configured to accommodate a plurality of circuit breakers that are both wired and plug-in. [0003] Circuit breakers are conventionally securely mounted to thin metal doors through door panel cutouts and associated fasteners. Assembly requires wiring to be assembled on the inner part of the door panel,...
