High Voltage Solid-Body Fuses for Use in Vacuum, Zero G, and Shock Environment 2000-01-3600
The high voltage power systems of satellites and spacecraft present unique fuse and fault protection challenges. High reliability fuses presently defined by MIL-PRF-23419 do not meet the increased voltage and amperage requirements for the next generation of spacecraft. Solid-body style fuses exhibit superior electrical and mechanical attributes that enable these fuses to perform reliably in the vacuum and high vibration and shock environments typically present in spacecraft applications. The construction and screening techniques for solid-body fuses described by MIL-PRF-23419/12 offer an excellent roadmap for the development of high voltage solid-body fuses.
