Abstract:
A clamping apparatus useful in clamping opposing pairs of stator coil windings of a turbine generator, the clamping apparatus comprising:a first pair of coil windings positioned parallel and in a spaced relation, thus having a gap therebetween;a support block positioned across the first pair of coil windings, said support block having an aperture therethrough, said aperture being aligned with the gap between the first pair of coil windings;a first retaining platform positioned adjacent said support block on a top side of said support block, the top side opposing the first pair of coil windings and extending across the first pair of coil windings, said retaining platform having a bore extending therethrough and aligned with the aperture of said support block;a second pair of coil windings positioned parallel and in a spaced relation, thus having a gap therebetween, said second pair of coil windings opposing said first pair of coil windings with alignment of the gaps thereof;a second retaining platform for extending across a surface of said second pair of windings, wherein said first and second pairs of coil windings are sandwiched between said first and second retaining platforms, said second retaining platform having a bore extending therethrough;first and second connecting insert members, each respectively carried within each bore of said retaining platforms, each of said connecting insert members having a through-hole and means for admitting an elongated rod therethrough; anda rigid elongated rod passing through the gaps between said first and second pairs of coil windings and passing through the through-holes of said connecting insert members, said elongated rod having bulbous shaped ends dimensioned for passing through each bore of said retaining platforms while the through-holes of said connecting insert members respectively prevent passage of the bulbous shaped ends therethrough, thus tension in said elongated rod biases said first and second pairs of coil windings between said first and second retaining platforms in a clamping arrangement.
