Title: Spark gap arrangement for surge voltage arresters
IPC: H01T1/04
Filed: 1960-10-06
Abstract: 915,660. Protective arrangements. BROWN, BOVERI & CIE A.G. Oct. 6, 1960 [Oct. 6, 1959], No. 34273/60. Class 38 (4). A surge voltage arrester comprises a voltage dependent resistor and a stack of spark gaps which are in the magnetic field set up by the follow current of an arc struck across the spark gaps, flowing through one or more blast coils. Each spark gap is made up of a round insulating plate 5 having a slot 6 into which two singlepiece electrodes 24 are inserted. A boss 23 on each side of the plates 5 fits into a hole 9 in the electrodes. Metal tongues 22 used to preionize the spark gaps are arranged so that they press against adjacent plates when the spark gaps are assembled. The slot 6 at the edge of each plate 5 widens to an opening divided into two parts 20, 21 and closed by the boss 12 which also prevents mutual rotation of the plates 5 in the assembled stack. Spark gap chambers are formed by an elevated edge 13 on each plate which also prevents lateral displacement of the plates. Gas channels 26 are formed by the wider elevations 15. Blast coils are mounted on each end of the assembled stack and are connected in parallel with similar spark gaps. The individual spark gaps 2 are formed by the lower electrode of the upper plate and the upper electrode of the lower plate, the stacking being such that each plate is rotated 90 degrees so that the two electrodes 24 forming a spark gap are mutually at 90 degrees, forming an arc space between adjacent plates extending over 270 degrees. The blast field in the magnetic coils causes an arc to move towards the edge of the spark chamber and gases thus formed are displaced downwards through the opening 20 in the lower plate and upwards through openings 21 in the upper plate. The gases flow through the channel 26 to the spark gap points of the upper and lower spark gaps, thus equalizing the pressure in the spark gap chambers, causing the arcs to migrate uniformly and extinguishing one another. The screw-like flow of current in the electrodes supports the magnetic field set up by the blast coils.

Abstract: 1,133,267. Wire-wrapping tool. FERRANTI Ltd. 31 July, 1967 [2 Aug., 1966], No. 34519/66. Heading B3E. A tool for forming secondary wrapped electrical connections comprises inner and outer longitudinal wrapping members, means for rotating the inner member relative to the outer member, the operative end of the inner member being hollow to receive a binding post and a conductor to be secured together and having a longitudinal recess to take a binding wire, the corresponding end of the outer wrapping member having an inwardly turned projection to catch and retain the end of a binding wire projecting from the recess, when the inner member is rotated relative to the outer member, whereby on such rotation the binding wire is wrapped tightly around an inserted binding post and conductor. The hollow body 10 of the tool is tapered at one end to form the outer wrapping member and has rotatably mounted in the opposite end a handle 11. Inside the body is the inner wrapping member 12 which has a pin and slot connection 16, 17 with the handle 11 and is acted on by a compression spring 18. At the operative end of the outer member is an inwardly directed projection 19, one face of which is at an angle to a radius of the tool, so that with the periphery of the bore of the body it forms a wedging opening. A part 20 of the wall also projects axially of the body. The inner member has a bore 12<SP>1</SP> which loosely receives the binding post and a conductor wire which is to be secured to it. There is a longitudinal groove 21 in the outer surface of the inner member, the groove being of a length to receive the binding wire with a short portion projecting. The tool is applied to the post and conductor, and the inner member rotated by the handle 11 and 14. The projecting end of the binding wire is carried round into the wedge-shaped opening and jams there. Further rotation of the inner member then wraps the wire tightly round the post and conductor. In a modification, Figs. 6-9 (not shown) the body has a reduced bore at its operative end and the wall is machined away to form a surface parallel to a diameter of the tool, the axial length of the surface being greater than the length of the reduced bore portion. The inner member has its end machined to form a flat surface at an angle to the tool axis and has a flat cut across it, to form a surface parallel to the tool diameter, the depth of the step being less than the wall thickness. This tool operates in a similar manner to the first embodiment.
