Abstract

1286855 Lightning arresters GENERAL ELECTRIC CO 9 Sept 1969 [16 Sept 1968] 44426/69 Heading H2H A lightning arrester comprises parallel columns of spark gaps and valve resistors, in series with a common valve resistance. Intermediate points in each column are connected by a resistor. The arrangement provides an arrester with a reduced protective level which is suitable for use with D.C. systems. In the arrester shown in Fig. 1, identical columns 4, 41 are connected in series with valve resistor discs VR3-VR10. The columns are linked by resistors R1, R2 which include between them equal fractions of the total, number of current-limiting gaps G1-G10, G11-G110 in each column, and of the total number of valve resistors VR1-VR10 in each path through the arrester. In operation, if it is assumed that the column 41 has brokendown and is conducting current, then the voltage across gaps G5 and G6 in the other column 4, which is not conducting, will be equal to the voltage across gaps G15 and G16 and resistors VR11 and VR12, which is a fixed proportion of the total voltage across the arrester independent of the current flowing. As the gaps G15, G16 build up voltage, at some point the gaps G5, G6 will spark over and the column 41 will clear. The number of gaps in each column between resistors R1 and R2 is chosen so that when gaps G5, G6 spark over, the increased voltage across the other gaps in column 4 causes them also to spark over. Subsequently, the two columns conduct alternately until the overvoltage condition is cleared. In a modification, Fig. 2 (not shown), triggered gaps are used in each column, and only a single resistor connects the two columns. Reference has been directed by the Comptroller to Specification 1,148,151.
