Current transformer assembly for dynamoelectric machines |
摘要 |
In order to provide an electrically insulated and fluid-tight assembly for securing a current transformer to the inside of a dynamoelectric machine housing, a screw is inserted through an aperture in the machine's housing to secure the current transformer to a portion of the inner surface of the housing wherein a first insulating material is used to insulate the current transformer from the housing; a second insulator is used to insulate the screw from the housing; and an insulating cap is secured over the top of the screw. An O-ring provides a fluid-tight seal between the cap and the machine housing and a retaining ring is utilized to secure the cap over the screw's head within the machine housing. Secured to the lower part of the current transformer is a soft iron magnetic shield which is threaded to engage the screw and serves to support the current transformer.
