Definitions

  • the invention relates to high tension transsupporting structures including poles and cross arms of one sort or another.
  • the effect of the static and earth wire in limiting the intensity of the lightning has no relation to the fact that they are supported by the same structure as the conductors,-this arrangement being merely a matter of convenience.
  • the static wire may be insulated fromthe pole and the ground wire may be carried vertically downward away from the pole, with possibly one guide type insulator for this vertical portion.
  • the ground wire should of course be brought in to the pole at an appreciable height above the ground, for instance six to eight feet, to avoid contact bydomestic animals and the like.
  • the feature of insulating the static and ground wires is in itself not new.
  • the invention comprises broadly the bonding of the metallic supports for the insulators and the interposition of fuses in the bonding wires, I have in the accompanyng drawings illustrated various detailed arrangements whereby the desired protective effect can be accomplished, it being, however, understood in advance that I do not intend to be limited to the exact arrangements.
  • Figure 1 is an elevation of a wooden pole and cross arms equipped with insulators of the pin type showing the preferred arrangement of bonding wires and fuses,
  • Figure 2 is a side elevation thereof
  • Figure 3 is an elevation showing substantially the same structure with certain of the fuses omitted.
  • Figure 4 is an elevation showing a modification
  • FIG. 5 is a similar view showing another modification
  • Figure 6 is a plan view of what is shown in Figure 5
  • Figure 7 is an elevation of another type of support with the invention applied to strings of depending insulators.
  • Figure 8 is a view similar to Figure 7 with certain fuses omitted
  • Figure 9 is a view of another common type of installation showing the invention applied in conjunction with suspension insulators.
  • Figure 10 is a similar view of another variation.
  • the numeral 1 designates a wooden pole carrying a plurality of wooden cross arms 2 on which are mounted metallic pins 3 carrying insulators 1 with which are connected the conductors'5.
  • a bracket 6 mounted on the top of the pole is a bracket 6 carrying an insulator 7 which supports the static wire 8.
  • the numeral 9 designates the guy wires which are secured to the pole in any ordinary or preferred manner and within which are interposed, in accordance with my invention, elongated insulators 10 which may be of the wood stick type and which are employed instead of the usual goose egg type as having a far greater puncture distance and leakage distance.
  • the numeral 11 designates a ground wire which is connected with the static wire 8 and which extends down and is preferably held away from the pole by an insulator 11 and which may be secured to a bracket 12 mounted on the pole at a point sufliciently far above the surface of the ground to avoid contact by domestic animals and the like.
  • the bracket itself is grounded either within or outside of the pole as indicated diagrammatically at 12.
  • I also provide wires 13 connected with the ground wire 11 and with the insulator pins 3 for bonding all together.
  • I have illustrated fuses 14 interposed in all of the bonding wires 13 and also fuses 15 in the wire between the points of connection of the bond wires, as well as a fuse 15 interposed between the wire 11 and bracket 6.
  • the fuses While there is given no detailed disclosure of the fuses, they may be and preferably are of the expulsion type, for instance as manufactured and sold by the General Electric Company, such fuses generally containing parts which will be forcibly ejected or expelled upon the passage of a current sufficiently strong to melt away and reduce whatever retaining means is provided for the expulsion means.
  • FIG 4 I have illustrated a somewhat different type of installation in which the wooden pole 17 carries a single cross arm 18 on which are mounted metal pins carrying insulators 20 for the conductors. There is also bracket 21 at the top of the pole carrying an insulator 22 for the static wire 22" to which is connected a ground wire 22". The pins are all shown as connected by a bond wire 23. Fuses 25 are interposed in the bond wire 23 between its points of connection with the pins and a fuse 25 is connected between the bond wire 23 and the ground wire 22'.
  • FIG 9 I have illustrated a common form of installation known as the H type in which there are provided two poles 38 carrying a cross arm 39 from which depend strings of insulators 40, two of which are located at the ends of the arm and the re maining one of which is located between the poles. Both poles are represented asprovided with brackets 41 carrying insulators 42 for the static wires 42*.
  • I provide bond wires 43 connecting whatever suspension elements are provided for the strings of insulators, and ground wires 44 connected with the static wires. Interposed in the bond wires 43 and ground wires 44 are fuses 45 and 45 respectively.
  • FIG 10 there is the same type of structure as in Figure 9 except that there is only one static wire with the necessary supporting bracket and insulator therefor.
  • the suspension elements for the outermost strings of insulators, or those at the ends of the arm are bonded together by a wire 46 which connects with a conductor 47in turn connected with the ground wire 44 leading from the static wire 42
  • a bond wire 48 connected with the suspension element for the intermediate insulator string and connected with the bond wire 46.
  • Fuses 49 are interposed in the bond wires 46 and 48 and a fuse 49* is provided in the connection 47.
  • bracket for supporting said last named insulator, said bracket being connected with said common connection, and fuses interposed in said common connection.
