GJB 298 military vehicle transient interference simulator is a simulation generator integrating ripple voltage, start-up disturbance voltage, surge voltage and peak voltage. The product is designed according to gjb298, which provides a reliable basis for the transient interference test of military vehicles. Ripple voltage is the voltage change of regular or irregular or both within a certain voltage range when the DC power supply system works in a steady state. Starting disturbance voltage refers to the undervoltage change of the voltage deviating from the steady-state voltage caused by the meshing of the starting motor gear and the engine ring gear during the starting of the engine. Surge voltage refers to a voltage that deviates from the controlled steady-state voltage characteristics. When the generator and battery work in parallel or the generator works alone, it is generated by the inherent law of the power system and the compensation effect of the regulator. When the battery works alone, surge voltage may appear only when the load is switched. Spike voltage refers to the high-frequency oscillation voltage that deviates from the controlled steady-state voltage characteristics. It is produced by complex high-frequency current when switching inductive load.
The aircraft surge voltage generator GJB 181b is designed in accordance with the relevant requirements of GJB 181 standard, and is used to simulate the changes of high-voltage, normal and low-voltage power supply characteristics of aircraft electronic equipment power supply, as well as the status of undervoltage surge, overvoltage surge and instantaneous power failure to provide an evaluation basis.
The aircraft peak voltage generator GJB 181a is designed according to the requirements of GJB 181 standard. During the flight of the aircraft, the execution of tasks and other functions, the power supply system must ensure the normal working state when performing various scheduled tasks. The main function of this product is to generate peak signals, which can apply 120 voltage peak signals with alternating positive and negative polarity to the tested equipment within one minute.
