International Classification:

B23P 1500

US Classification:

2988922, 2988921, 29889

Abstract:

A process for installing a stator slide under a stator wedge in a radially oriented slot of a stator core assembly includes: a) loading windings in the radial slot, the radial slot having axially extending dovetail grooves in opposing sidewalls thereof; b) loading at least one stator wedge and stator slide in the dovetail grooves of the slot, and tightening the at least one stator wedge with the stator slide; c) loading at least one additional stator wedge in the dovetail grooves; d) locating at least one additional stator wedge slide relatively loosely under the additional stator wedge; and e) using the at least one stator wedge as a force reaction point, applying a force to the additional stator slide to drive the additional stator slide under the additional stator wedge. The tool for driving the stator slide under the stator wedge has a frame including a pair of elongated rail members; a force application cart located between the rail members, the force application cart having a force block thereon; a drive connected to the frame, substantially intermediate opposite ends of the frame; a lead screw threadably engaged at one end with the force application cart and connected at an opposite end to the drive such that the drive rotates the lead screw when actuated. Rotation of the lead screw causes axial movement of the force application cart and the force block against the slide in a tightening direction.

Abstract:

A radial clearance measurement device includes a pair of opposed drive heads, connected by an adjustable strut. Each drive head is fitted with a radial distance measurement device including a plate adapted to slide within a dovetail groove in a radial stator core slot, a spring-loaded plunger adapted to engage a surface of an armature bar located in the radial stator slot, and a linear voltage displacement transducer for measuring distance between the dovetail groove and the armature bar. The device is adapted to move through the bore of the stator, with the plungers engaged with armature bars in diametrically opposed radial stator core slots.

Abstract:

Radial pressure is applied to a turbine generator armature bar using a simple hand held device that can be readily manipulated by a single human operator. A retainer platform has two wedge shaped portions with handles, and by the operator sliding the wedge shaped portions with respect to each other the operative width of the platform may be adjusted, including to slide and lock the platform in a conventional dovetail slot in a stator. An inflatable bladder is positioned on or mounted to the top surface of the platform and is dimensioned so as to apply radial pressure (for example through a filler) to armature bars mounted in the stator. A conduit, preferably having a valve with quick-release actuator in it, extends from the inflatable bladder and connects to a source of gas under pressure.

International Classification:

US Classification:

310201, 310 52, 310 54, 310260

Abstract:

A new and improved header design for a fluid tight, current carrying header that reduces direct contact between the liquid coolant and brazed joints. More specifically, the present invention provides for a header with hollow strands for carrying a coolant, and solid strands, the hollow strands being longer than the solid strands, the hollow strands grouped together at a first end of the header to form a hollow strand package, and the hollow strands and the solid strands grouped together at a second end of the header to form a mixed strand package. The hollow strand package may be fused to a liner of the header. This construction reduces water contact with the current carrying braze and groups the fluid carrying hollow strands in a separate hollow strand package where a reliable, corrosion-resistant metal fusing process can be applied to provide a reliable leak proof seal. By separating the hollow strands from the solid strands, hollow strands can be made from materials other than copper and that have low electrical loss, are corrosion-resistant and permit high fluid flow velocities without erosion.

Abstract:

A tool for driving a stator slide under a stator wedge within a radial slot of a stator core includes a frame including a pair of elongated rail members, the frame provided with a pair of handles at respective opposite ends of the elongated rail members. A force application cart is located between the rail members, the force application cart having a drive block thereon. A drive is connected to the frame, substantially intermediate opposite ends of the frame, the drive having an on/off trigger located on one of the handles. A lead screw is threadably engaged at one end with the force application cart and connected at an opposite end to the drive such that the drive rotates the lead screw when actuate; wherein in use, rotation of the lead screw causes axial movement of the force application cart and the drive block along the elongated rail members.
