Embodiment Construction

[0034] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0035] The invention proposes an improved test device and test method for arc faults. On the one hand, the present invention can simulate the fault arc that occurs in the circuit under various triggering factors, so as to achieve the purpose of reproducing the fault arc. On the other hand, the present invention can measure the arc energy at different locations around the point where the fault arc occurs, so as to evaluate the impact of the fault arc. In yet another aspect, the present invention allows for the measurement and evaluation of damage to affected objects around the point where an arc fault occurs.

Abstract

This paper discloses an arc fault test device and test method. The arc fault test device may include: a wire harness, which transmits the electric energy of the power supply to the load unit, and the wire harness includes a plurality of wires and wherein at least two insulation layers of the wires have cutouts to expose conductor parts; an arc fault trigger unit, which is used for triggering an arc at the exposed conductor portion of the wire harness when the wire harness is energized; and an arc energy measuring unit arranged around the exposed conductor portion of the wire harness to measure arc energy when the exposed conductor portion is arced. A method for conducting an arc fault test is also disclosed.

Description

technical field [0001] The invention generally relates to the field of fault simulation, in particular to an arc fault test device and test method. Background technique [0002] According to FAA and EASA civil aircraft failure statistical reports and related literature, the frequency and severity of aircraft arcing faults (Aircraft Arcing Fault) have been increasing in the past decade. The harm is mainly reflected in the fact that the instantaneous temperature of the arc fault can reach as high as thousands of degrees Celsius, which not only causes damage to the lines of the aircraft power supply and distribution system, and the power consumption system, but also seriously affects the EWIS (Electrical Wiring Interconnection System) and surrounding systems. If the arc fault plasma arc column sprays and pierces the hydraulic and fuel pipelines, it will cause fire and explosion events, which will have a serious impact on the overall safety of the aircraft. [0003] The existin...
