| 内容記述 | With the advance of development of space utilization, the size and the electric power capacity of a spacecraft have become larger. It is necessary to generate and transmit the elecricity with higher voltage for the higher electric power capacity. Power wires transmitting the electricity are occasionally distributed outside the body and/or the solar array paddles of the spacecraft. The wires are possible to be damaged by impacts of space debris and/or heat cycles. Then the conductors of the wires are exposed to space.In these situations, when spacecraft charging due to space plasma induces flashover on the surface materials of the spacecraft, discharge plasma formed near the exposed conductors of the wires is possible to cause sustained arcing discharge between the conductors. The occurrence of these discharges causes malfunctions or damages to the spacecraft.From these viewpoints, we carried out experiments for the sustained arcing discharges between wires triggered by surface flashover on a thermal control material, silvered Teflon FEP, due to electron beam irradiation. A pair of wires with partially lacked ETFE insulator laid on the FEP film with 125microm thickness was irradiated by electron beam with the energy smaller than 20keV in a vacuum chamber. As a resistor R was inserted between two wires, potential difference R･I was formed between the two wires by flowing current I from a current source. Surface flashover occurred when the surface potential of the FEP film became over -15kV. At the time of the flashover, arcing discharge occurred between the conductors of the wires. For example, the arcing sustained for about 80micros in the case of the potential difference RI=100V. We obtained the result that the arcing time is dependent on the potential difference RI and the charge quantity released by flashover. | |||||||||||||
