Abstract

The invention discloses an automatic detection test system for operating characteristics of an arc fault protection electric appliance, and the system is characterized in that the system comprises an arc generator, a carbonized cable arc generation device, a cable cutting device, and a shielding load device RL; the arc generator or the carbonized cable arc generation device is connected with the cable cutting device in parallel and then connected into a test loop together with the shielding load device RL, electric appliances used in actual life are simulated through the shielding load device RL, and in the process that the shielding load device RL simulates operation of the electric appliances, the purpose of verifying the performance of the arc fault protection electric appliance to be tested in the test loop is achieved by connecting the arc generator or the carbonized cable arc generation device and the cable cutting device into the arc. According to the invention, automatic switching of all test processes, automatic switching of a resistive load and a shielding load and automatic closing of a test object are realized, and the test effect and the test efficiency are greatly improved.

Description

technical field [0001] The invention relates to an automatic detection test system for the action characteristics of an arc fault protection device (abbreviated as AFDD hereinafter). Background technique [0002] The existing AFDD operating characteristic test system is composed of a test port, an arc generator, a carbonized wire arc generator, a knife-cut arc generator, a shielding load, and a resistive load. Its main disadvantage is that the carbonized wire arc generating device cannot automatically perform arc generation and judgment, and the arc current consistency and test safety are relatively poor. Moreover, the existing AFDD operating characteristic test system can only switch the test circuit manually, and the manual switch will affect the result of the arc test. Contents of the invention [0003] The technical problem to be solved by the invention is: the existing AFDD action characteristic test system cannot automatically switch the test loop. [0004] In orde...
