Abstract

PURPOSE: To construct a waterproof current transformer with high reliability by separately constructing an annular enclosure body to house the current transformer from a container in which the charge section conductor is arranged and discharging the rainwater immersed into the mounting section from a channel.
CONSTITUTION: An annular enclosure body consisting of both the shielding pipe 15 to form a cover 5 and an inside plate and a support plate 11 to form a bottom plate is set up around a container 7a in which a charge section conductor is arranged and a current transformer 6 is housed in it. Packings 8 and 14 adheres tightly among the cover 5, support plate 11, and shielding tube 15 and a shielding section 5a which is bent downward is set up so as to enclose the packing 14. Accordingly, the rainwater immersed from the joint between an intermediate plate 13 and a plate 3 is discharged through the channel 17 between the container 7a and the shielding tube 15. Since the packing 14 is protected from rainwater, perfect water structure is enabled.
