Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] This embodiment provides a short-circuit breaking test system for marine electrical appliances, see figure 1 , the short-circuit breaking test system includes a power supply device 11 and a swing test device 12 . The swing test equipment 12 is used for simulating the three degrees of freedom motion of the hull, roll, pitch and yaw, and provides a sea swing environment for the tested marine electrical appliances 13 . Roll refers to the side-to-side swin...

Abstract

According to a short-circuit on-off test system for a marine electrical appliance, three-degree-of-freedom movement of rolling, pitching and yawing of a ship body is simulated through a swing test device, and a marine swing environment is provided for a tested marine electrical appliance; meanwhile, required electric energy is provided for the tested ocean electric appliance through power supply device, and a short-circuit on-off performance test is carried out. The short-circuit on-off test of the marine electrical appliance in the marine swing environment is realized, and the accuracy of tatest result is further improved.

Description

technical field [0001] The invention relates to the field of electric appliance testing, more specifically, to a short-circuit breaking test system for marine electric appliances. Background technique [0002] Marine electrical appliances refer to electrical products that work in a sea-swaying environment. Marine electrical appliances need to be able to break the short-circuit current in time when a short-circuit fault occurs in the line, so as to ensure the safety of equipment and personnel on board. At present, the short-circuit breaking test of marine products cannot simulate the special environment of sea swaying, resulting in inaccurate test results. Contents of the invention [0003] In view of this, the present invention proposes a short-circuit breaking test system for marine electrical appliances, in order to realize the short-circuit breaking test of marine electrical appliances in a sea swaying environment, so as to improve the accuracy of test results. [000...
