Description

technical field [0001] The invention belongs to the technical field of an engine ignition nozzle detection device, in particular to an engine ignition nozzle discharge voltage automatic detection device. Background technique [0002] The aircraft engine is the heart of the aircraft, and the aviation ignition system is one of the important components of the aircraft engine. As an important component of the ignition system, the ignition nozzle is an important component of the ignition system, and its performance directly affects the reliability and safety of the engine. The discharge voltage of the ignition nozzle of the engine is an important parameter to test its performance. The discharge voltage of the ignition nozzle refers to the minimum input voltage that breaks down the ignition nozzle to generate a discharge spark. [0003] At present, the detection of the discharge voltage of the ignition nozzle of aerospace engines still uses a mechanical knob type autotransformer t...
