关于防止电子设备在低气压下打火问题

PROTECTION OF THE ELECTRONIC EQUIPMENT FROM CORONA AT LOW ATMOSPHERIC PRESSURE

飞行器高压电源等电子设备在高空极易打火,发生打火就不能工作。如何解决这方面问题,目前国内研究甚少。本文提出的机械密封和灌封联合措施,是防止电子设备在低气压下打火的一条有效途径。

When a missile is flying at high altitude, corona occurs easily in the electronic equipment including the high voltage supply, thus disabling the electronic equipment. To protect the electronic equipment from corona at low atmospheric pressure, an effective measure, combination of the mechanical encapsulation with electronic encapsulation, is presented in the paper.
