ELECTRICALLY-INSULATING DEVICE FOR ATTACHMENT OF BLANKET MODULE ON VACUUM HOUSING OF FUSION-TYPE REACTOR Russian patent published in 2015 - IPC G21B1/17 

FIELD: power industry.

SUBSTANCE: electrically-insulating device for attachment of a blanket module on a vacuum housing of a fusion-type reactor includes a flexible hollow support with flanges, a bolt and an attachment sleeve. One flange of the support is installed in a mounting seat of the vacuum housing with formation of a threaded connection to it, and the other flange is connected to the blanket module by means of a bolt so that electrical insulation is provided. In the end face of the threaded part of the bolt there is a mounting hole, and the bolt head is located in the cavity of the flexible support. The attachment sleeve consists of two elements rigidly attached to each other along conical surface to which an electrically-insulating layer is applied. The sleeve has a head corresponding as to the shape to the mounting hole of the bolt, and a thin-wall cylindrical end. The sleeve head is installed in the above bolt hole, and its thin-wall end is fixed by its deformation in the module.

EFFECT: excluding self-unscrewing of the bolt of the flexible support with simultaneous preservation of electrically-insulating properties of the device.
