摘要

PURPOSE: A connection terminal box for partial discharge measurement of an ultrahigh voltage power cable connection box is provided to easily perform maintenance work using a simple opening structure. CONSTITUTION: An external box and a cover are comprised of metal materials. A connector fixing stand(170) installed inside of the external box includes a plurality of connection connectors. An inlet(210) is formed on a side surface of the external box and receives a coaxial cable for partial discharge measurement.
