| 释义 | > as lemmasrestriking voltage restriking voltage n. Electrical Engineering the voltage formed across two electrodes in an a.c. circuit at zero current and during the subsequent extinction of an arc between them, causing (if sufficiently high) the restriking of the arc; spec. that across the contacts of a circuit breaker, switch, etc., after they are separated.

E. Browne in Physical Rev. 36 734 For the zinc arc, the restriking voltage is 280 volts. 1951 Brit. Jrnl. Appl. Physics 2 173/1 It is possible that the already initiated arc will be interrupted at a current zero, owing to the insufficiency of the available restriking voltage. 2004 A. Wright & P. G. Newbery Electric Fuses (ed. 3) iii. 56 The gap produced by burnback is long enough to withstand the restriking voltage. < as lemmas |
