1、 Introduction
With the increase of the type and quantity of airport aircraft equipment, new requirements are put forward for the adaptability of aircraft ground power vehicles and the endurance of support. This product combines the characteristics of general products of the company, and increases
The power supply module and battery endurance module are suitable for different aircraft power supply requirements. At the same time, the cockpit information system is added to monitor the battery power status, power work records and other information, so as to improve the management water of the power car
Ping.
The scheme has 6 power supply voltage levels, namely DC 28V, DC 56V, DC 270V, 400Hz AC single-phase 115V, three-phase four wire 115 / 200V, greatly expanding the model support adaptation
And various power supply modes can be combined for power supply.
The system includes battery endurance module, battery unit, high voltage DC power supply module, AC power supply module and cockpit information system.
The battery life module consists of a diesel generator and a battery charger. It has two main functions: one is to connect the mains power input to charge the battery pack; the other is to lower the battery pack to one when working in the outfield
When the power is fixed, start the diesel unit, provide power to the load through the battery charger, and extend the operation time of the outfield. The capacity of diesel engine can be selected according to the general working power of the field, and the high-power output depends on power storage
The capacity of the pool. Reduce equipment cost and diesel consumption.
In addition to 28V and 56V power supply, the battery unit also has the battery power detection function in the original system, which is convenient for users to understand the battery energy storage status, and provides a good guarantee for the flight mission.
The high-voltage DC power supply module is responsible for providing 270V aircraft power supply requirements. The modular structure is adopted. The power of a single DC / DC module is 15kw. The number of modules in parallel is selected according to different power levels, which is conducive to standardization and system expansion. The output of the DC / DC part is 270V, which can directly supply power to the fourth generation machine, as well as the later stage inverter power supply.
The AC power supply module is responsible for providing the AC 400Hz power supply demand. Modular structure is also adopted, each module is three-phase output / 15KVA, and the parallel number of modules can be selected according to different power levels, which is advantageous
In standardization and system expansion. Output three-phase four wire 115V, 400Hz for load power supply. The power supply DC / AC unit of the scheme is composed of three groups of modules in parallel.
Cockpit information system includes battery inspection, operation control of each component and status monitoring. Integrated information screen is installed in the cockpit.
Spare parts: the power supply consists of DC / DC and DC / AC modules. No matter how many power supplies are used or the power level is different on site, only these two modules are needed.
