CLAMPING DEVICE FOR A CORE FORM TRANSFORMER

摘要

The present invention is an improved dynamic clamping device for retaining t he coil assembly of a transformer under the appropriate compressive force throughout operational lifetime of the transformer. The modular clamping device compris es a cylinder having a lower portion for engaging a first structure in the transformer and a piston moveable within the cylinder. The piston and the cylinder define an internal chamber. The piston includes an upper portion for engaging a second structur e in the transformer. At least one of the first and second structures is mechanically coupled to the coil assembly. A spring is disposed within the internal chamber and contacts the piston and the cylinder. The spring forces the piston away from the cylinder. The upper portion of the piston includes a threaded rod and nut combination allowing f or it to be adjusted to the appropriate height in the transformer. The device also includes a compression retaining structure for retaining the appropriate force on the spring prior to installation.
