AI Technical Summary
Existing electrical fire fault simulation equipment has limited functionality, cumbersome structure, and high cost, and cannot effectively simulate a variety of electrical fire faults.
An integrated test device for simulating electrical fire faults was designed. It adopts a linkage drive component and multiple test modules, including short circuit, local overheating and arc fault test modules. Multiple faults can be simulated by sharing the same drive component. The module layout is compact and reduces equipment cost.
It can simulate various electrical fire faults, has a compact structure, reduces manufacturing costs, and provides multi-functional testing capabilities by protecting test personnel through a protective enclosure.
