THREE-PHASE BATCH TYPE PHOTOCURRENT TRANSFORMER

摘要

PURPOSE: To obtain a three-phase batch type photocurrent transformer with a common closed container miniaturized diametrically. ;CONSTITUTION: One branch tube 1a is formed diametrically in a common closed container 1 which houses center conductors 2A-2C and photocurrent transformers 3a-3c of three phases and three phases of optical space transmission parts 6A-6C are arranged being concentrated in the branch tube 1a to lead signals from the photocurrent transformers 3A-3C outside the common closed container 1 through optical fibers 5A-5C. In the case of a common closed container having a branch part being protruded diametrically at the end thereof, three phases of the optical space transmission parts are arranged being concentrated at an axial end of the common closed container having the branch part without forming the branch tube 1a.;COPYRIGHT: (C)1993,JPO&Japio
