随着环保意识的提升,国内外机场给停驻机场的飞机提供动力的电源,普遍采用桥载400Hz电源(见图1),既降低了飞机的耗能成本,又为机场节能减排降噪,打造绿色机场发挥重要作用。但桥载电源在给飞机充电时,如使用不当,易发生桥载400 Hz电源充电电缆拉坏航空器等事件,对机场、航空公司的日常安全生产运行,造成极大的不良影响。通过行业内部了解,目前国内外桥载电源的工作原理与技术防护都大致相同。国内外机场使用桥载电源保障
With the promotion of environmental protection, domestic and foreign airports provide power to airplanes parked in the airport. Generally, the 400-Hz power supply is used (see Figure 1), which not only reduces the aircraft’s energy cost but also reduces noise for airports , To create a green airport play an important role. However, if the bridge-loaded power supply charges the aircraft, improper use and easy occurrence of an incident such as loading a 400 Hz power cable on the bridge and pulling the aircraft will have a great adverse impact on the daily safety operation of airports and airlines. Through the industry’s internal understanding, at home and abroad at present the working principle of power and bridge protection are roughly the same. Domestic and foreign airports use the bridge with power protection
