Problems solved by technology

The installed quality of the primary power distribution device is particularly important, which is related to whether the aircraft power supply system can work normally. At present, there is no corresponding special tester for supporting tests. A simple test through the existing test connection cannot meet the requirements of the product to be tested before installation. Calibration requirements cannot guarantee the quality of the installed and tested products, and there are certain safety hazards

Description

technical field [0001] The invention belongs to the technical field of power distribution test, and in particular relates to a comprehensive test device and a comprehensive test method of a primary power distribution device. Background technique [0002] With the rapid development of electronic technology, my country's aviation airborne power distribution system devices tend to be comprehensive and intelligent, and the power distribution system of modern aircraft is developing towards electrical multiplex transmission systems. The traditional single power distribution device test method has been unable to adapt to the detection of new power distribution devices. [0003] The power distribution system is the key component system of the aircraft power supply system. It is composed of wires, power distribution devices and protection devices, etc., and is used to transmit the electric energy generated by the power supply to the electrical equipment. The primary power distributio...
