Abstract

1,101,674. Fusible cut-outs. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 2 June, 1965, No. 23485/65. Heading HlN. [Also in Division H21 A re-usable sealed enclosure for H. T. protective device such as a circuit-breaker or a (copper) fuse link 27 comprises a cylindrical insulating shell 2 having a metal closure plate 6 sealed to one end whilst the other end is closed by a metal plate having its flange 8 sealed (e.g. brazed) to an annular flange 9 sealed to shell 2, removal of plate 7 permitting removal of the fuse link 27 and the shielding arrangement 11, 12, 13, 14 for cleaning or replacement. The shielding arrangement comprises ceramic rods 18 carrying overlapping stepped cylindrical members such as 12, 14 of copper, nickel, molybdenum or stainless steel and is held by the plate 7 through spacers 22 and springs 23. The fuse link 27 is held in slight tension. A sleeve 29 on its lower end is screwed into a threaded hole 33 in a resilient bracket member 31 by rotation of plate 7 while its upper end is held in a socket block 42 carried by a resilient curved tube 39. The enclosure may be exhausted, after sealing, through tube 37 and, instead of having a vacuum therein, may be filled with nitrogen or a mixture of inert gases. A flat fuse link with heat sinks (Fig. 4, not shown), may be used.
