Abstract

A transformer clamp is provided that includes a first plate having a bend having a predetermined curvature between a first end and a second end of the clamp. The clamp includes a second plate attached to the first plate and bent based on a curvature of the bend, where the curvature enables the clamp to distribute substantially uniform pressure on a first surface of the transformer coupled to the clamp. The clamp may have a mounting mechanism. A method includes determining a curvature for a first sheet and forming a bend in the sheet based on the curvature. The method includes bending the second plate along the bend to form a curved contact surface having a curvature based on the curvature, and re-deforming the curved contact surface to apply a substantially uniform pressure on a surface of the transformer coupled to the clamp.

Description

technical field [0001] The present disclosure relates generally to transformer clamps, and more particularly to transformer clamps and related methods. Background technique [0002] Transformers typically include a core, coil, and transformer holder structure. The transformer clamp structure provides the stiffness required to withstand the loads in the transformer under different operating conditions (eg, lifting transformers, short circuit operation, and transport transformers). In addition, the clamping member must provide sufficient pressure to the core plate member to reduce or prevent vibration of the transformer core plate member during operation of the transformer. [0003] There are various methods for achieving stress on the transformer core. Typically, set studs, rivets, or bolts that penetrate the core or around the core and are attached to the clip are used to achieve the pressure. this is in figure 1 shown in. Using these add-ons often increases the manufac...
