某直升机专用电源系统供电特性研究

Study on Power Supply Characteristics of a Helicopter Special Power Supply System

某直升机加装了较多大功率选装设备,原机电源系统无法满足用电要求。为解决选装设备供电问题,该型机为其加装了专用电源系统,为电动绞车和空调系统两项设备供电。该套系统为首次装机,需验证其供电特性是否符合GJB181-86中B类供电要求,以确保专用电源系统能够满足电动绞车和空调系统用电需求。

A helicopter is equipped with more high-power optional equipment,the original power supply system can not meet the requirements of power consumption. In order to solve the problem of power supply for the selected equipment,the special power supply system is installed for the machine,which supplies power for the electric winch and the air conditioning system. The system is installed for the first time. It is necessary to verify whether its power supply characteristics meet the requirements of Class B power supply in GJB181-86 to ensure that the special power supply system can meet the electricity demand of electric winches and air conditioning systems.
