A System For Inserting Multiple Insulating Cylinders Of Varied Length

A System For Inserting Multiple Insulating Cylinders Of Varied Length Over Core Bar Of 210 Mw Thw Sets

Abstract: The invention relates to A system for inserting multiple insulating cylinders of varied length over core bar of 210 MW THW sets, the system comprising a base constituting a solid cylindrical shaped body formed of a plurality of metal plates flexibly joined; hydraulic cylinders to generate required pressure for the insertion of the insulating cylinder over the core bar; a hydraulic jack/ram with hydraulic pipe for application of said generated hydraulic pressure; a handle hingedly joined to the hydraulic cylinder; a kinematic link through said hydraulic pipe to drive the piston of the hydraulic cylinder upon movement of the handle; a ram transferring the generated pressure to the periphery of the insulating cylinder; a bar pusher to maintain the length of the core bar inside the insulating cylinder; a stopper blocking a first end of the core bar; a rod and plate to prevent bending of the insulating cylinder during repeated insertion on the core bar; and a device having a first structural component for laying the insulated core bar, and a second structural component for at least one supporting roller allowing the insulating cylinder to smoothly slide; and a plurality of wheels provided under the first and the second structural components to make the system portable, wherein the length of the first structural component is decided according to the length of the insulating cylinder with a provision to adjust the decided length due to variable lengths of the Core bar by using said stopper, wherein the length of the second structural component is decided according to the number of rollers used corresponding to the length of insulating cylinder to slide over the roller, wherein the axis of the jack/ram, core bar and insulating cylinder is identically selected as to a required gap of 0.4 to 0.7 mm between the insulating cylinder and core bar.
