PORT ASSEMBLY FOR SELECTIVE INSERTION OF OBJECTS INTO A WELL

摘要

A port assembly is receivable in an opening allowing access to the interior of a transformer. The port assembly includes a body and a port cover. The body is receivable in the opening and has a substantially axial opening therethrough. The axial opening allows access to the interior of the transformer through the port. The port cover is disposed on the interior of the transformer and is movable relative to the body between a sealed position sealing the axial opening and an open position allowing access to the interior of the temperature well. The port cover is biased toward the sealing position and moves to the open position upon being acted upon by an elongate tool inserted into the temperature well through the axial opening in the port.
