Title: Improvements in or relating to devices for indicating when a flash-over has occurred across an insulator or chain of insulators
IPC: H01T1/12
Filed: 1930-12-31
Abstract: 369,671. Indicating faults. BULLERS, Ltd. and DAGNALL, H. C. R., 6, Laurence Pountney Hill, London. Dec. 31, 1930, No. 39334. [Class 37.] In combination with an insulator or chain of insulators for use in an overhead power line and having arcing-horns between which a discharge may occur away from and along the length of the insulators, there is arranged in the path of the discharge an indicator which is displaced, fractured, or destroyed when a discharge occurs. A chain of insulators 1, Fig. 1, is provided with arcing-horns 5 and an arcing-ring 6 between which a discharge takes place on the occurrence of a surge of lightning. Arranged in the path of this discharge are balls 13 of fusible metal, such as " Wood's metal," carried at the ends of arms 10 which are secured to the metal cap of an insulator near the centre of the chain. On the occurrence of a discharge, the balls 10 are fused and indicate, by their disappearance, that a discharge has taken place. The fusible elements may be of different shapes and may be attached to the ends of the horns 5 instead of to intermediate arms 10. They may be arranged so that, in consequence of their fusion, the length of the gap between the horns 5 and ring 8 is increased, thus extinguishing the arc. Instead of fusible metal, a readily ignitable material, such as celluloid, or a material which would be broken by the discharge may be employed. For example, a strip of celluloid or of fusible metal may be threaded through a hole in the end of each arcing horn 5. A star-shaped disc of fusible metal or combustible material may be secured to the arcing horn by a pin. An indicating arm hinged to the end of the horn 5 may be held up by a fusible metal cap and dropped into indicating position by destruction of the cap. Fig. 8 shows an insulator 27 carried by a. pin 28 on a cross-bar 29 and provided with an arcing horn 5. Secured to the cross-bar 29 by a bolt 30 is a fusible or ignitable indicating-member consisting of a socket 20 and laterally extending arms 21 arranged to project beyond the breadth of the cross-bar so as to be visible from below.

[Also in Division H3B] A magnetic logic device having a rectangular loop ferrite core 1 (Fig. 1) with a soft iron shunt 6 is provided with oppositely wound control windings 4, 5 which determine whether or not an output is obtained from a secondary winding 3 when A.C. is applied to primary winding 2. In the embodiment shown the control current produces opposite saturating fluxes in the two halves of the core 1 so that zero output is obtained if a control current exists as well as when the input A.C. fails. In an alternative form (Fig. 2, not shown) the shunt is bridged by a permanent magnet 12 which by itself saturates the core 7 and prevents coupling between the primary and secondary windings 8 and 9, the effect of this magnet being overcome by the application of a control current. A number of alternatively usable windings carrying control currents may be used. Devices as described respectively with reference to Figs. 1 and 2 may be connected with their primary windings in series and their D.C. control windings in series (Fig. 3, not shown) so that the output of one is the inverse function of that of the other. Several devices may be connected so that the secondary winding of one supplies the primary winding of the next.
