Definitions

  • rl ⁇ his invention relates to oil immersed switches and has reference particularly to the venting of such switches.
  • the object of the present invention is to provide means for preventing this discharge of oil while permitting the gases to escape.
  • the invention consists broadly in the provision, in association with the vent, of a chamber into which the oil can be thrown by the explosion and from which it can then drain back into the switch.
  • Figure 1 is a vertical section through one embodiment of the invention.
  • Figure 2 is a plan of the same with interior parts indicated in dotted lines.
  • Figure 3 is a. vertical section of another form of the invention.
  • a metal dome 1 has integral with it an inwardly projecting horizontal annulus 2 provided at its inner edge with a vertical iiange 3.
  • An annular oil collecting channel 4 is thus formed within the dome.
  • the lower surface of the annulus 2 bears on the uppermost member of a pile of annuli 5 which alternate with washers or strips 6 to form a vent of more or less usual form.
  • washers are shown somewhat ⁇ exaggerated in thickness in the drawings.
  • each of these bolts is threaded into a hole in the annulus 2 and lies flush with the upper surface of the annulus; the lower end passes through a hole in the housing and is secured by a nut 11.
  • annular venting plates and their spacing members are clamped between the dome member and the top of the switch housing, tubular bolts being employed to provide the necessary drainage pipes.
  • the lower edge of the dome is extended downwards on one side of the vent at 12 to protect the operator from flaming gas forced through the vent by explosions within the switch housing.
  • the switch housing 20 has an external iiange 27 and the dome member 21 is provided with an external flange 22
  • the pile of annular venting plates 5 and their members 6 are secured between these two fianges by bolts 29 and nuts 31. Draining holes 30 are cut through the pile of plates.
  • the dome member has an additional vertical iange 32 on one side to protect the operator. Bale plates may be used similar to those shown in Figure 1.
  • a vent for oil immersed switches comprising a laminated structure applied to an opening in the top of the switch containing casing, said laminated structure forming a vent for the escaping gases, an opening 95 through the laminated structure through which oil displaced by rises in pressure passes upwardly, a dome above said opening adapted to deflect the displaced oil into a channel above the laminated structure, and drainage 100 holes leading from said channel back to the switch casing.
  • a vent for oil immersed switches comprising a laminated structure applied to an opening in the top of the switch containing casing, said laminated structure forming a vent for the escaping gases, an opening through the laminated structure through which oil displaced by rises in pressure passes upwardly, balile plates beneath said opening, a dome above said opening adapted to dellect the displaced oil into a channel above the laminated structure, and drainage holes leading from said .channel back to the switch casing.
  • a vent for oil immersed switches comprising a laminated structure applied to an opening in the top of the switch containing casing, said laminated structure orming a vent ior the escaping gases, an opening through the laminated structure through which oil displaced by rises in pressure passes upwardly, a dome above said opening adapted to deliect the displaced oil into a channel above the laminated structure, a spindle depending from the top of said dome, baille plates carried on the lower end of said spindle and located beneath said opening and drainage holes leading from said channel back tothe switch casing.
  • a vent for oil immersed switches comprising a series of superimposed annuli, washers separating and alternating with said annuli, an opening in the top of the switch casing which said annuli and said washers border, a dome structure havin@ a flange abutting upon the pack of annuli and washers, bolt devices for clamping the dome, annuli and washers to the top oi' the switch casing and holes passing through said' annuli and said washers through which oil thrown up into the dome drains back into the switch casing.
  • a vent for oil immersed switches comprising a series ot superimposed annuli, washers separating and alternating with said annuli, an opening in the top of the switch casing which said annuli and said washers border, a dome structure having a ange abutting upon the pack of annuli and washers, bolt devices for clamping the dome, annuli and washers to the top of the switch casing and holes passing through said bolts through which oil thrown up into the dome drains back into the switch casino'.
  • a vent for oil immersed switches comprising a series of superimposed annuli, washers separating and alternating with said annuli, an opening in the top or" the switch casing which said annuli and said washers border, a dome structure having a lange abutting upon the pack oi annuli and washers, a spindle depending from said dome, battle plates carried upon the lower end of said spindle and located beneath the opening in the top of the switch casing, bolt devices for clamping the dome, annuli and washers to the top or the switch casing and holes passing through said annuli and said washers through which oil thrown up into the dome drains back into the switch casing.
