Full wave rectifier for single or polyphase AC voltage - has excitation diodes connected to generator excitation winding

摘要

The system includes two parallel d.c. busbars and there is an insulating spacer which is fitted between them. There is a hole (7) which is accessible from outside, and which is provided in the spacer (5). Excitation diodes are mounted in a housing (8) which has a projecting part (9) which fits into the hole (7). The housing has at least one projection (10) which extends towards one of the busbars (1, 3). It enters into a recess (11) in the hole wall so that the housing (8) is firmly locked into position.
