Abstract: For retention of coils in cores of large dynamo-electric machines, a side filler is used between the insulated coil and the core slot wall with different surface characteristics on each side of the side filler. The surface adjacent the slot wall has a coefficient of friction that is relatively high compared with the coefficient of friction of the surface adjacent the coil. The surface adjacent the slot wall also tends to have a greater degree of adhesion with the slot wall under heat and pressure, than does the surface of the side filler adjacent the coil. These qualities can be provided by employing as the side filler a member having a surface comprising a fluorocarbon polymer adjacent the coil while the other surface includes a different, more conventional, resinous material. The combination of the invention permits free movement of the coil during thermal cycling without tending to remove the side filler from the slot and without damaging the coil insulation.
Abstract translation: 为了在大型发电机的铁心中保持线圈，在侧面填充物的每一侧上，在绝缘线圈和芯槽壁之间使用侧填料，具有不同的表面特性。 与槽壁相邻的表面具有与邻近线圈的表面的摩擦系数相对较高的摩擦系数。 与靠近线圈的侧填料的表面相比，靠近槽壁的表面在加热和压力下也倾向于具有与槽壁更大程度的粘附。 这些质量可以通过将侧填料用作具有邻近线圈的氟碳聚合物的表面的构件，而另一个表面包括不同的更常规的树脂材料。 本发明的组合允许在热循环期间线圈的自由移动，而不倾向于从槽移除侧填料并且不损坏线圈绝缘。

Abstract: PATENT 4,146 12 PD-9054 A plurality of connector members are provided, each of which is shaped to fit between two adjacent strands in a column of strands on a stator winding (i.e., by manual insertion). Each connector member has a first side provided with an electrically conductive material and a second side provided with an electrically insulating material. An electrically conductive lead is electrically connected to the electrically conductive material on an associated connector member. In this manner, a plurality of electrically conductive leads are connected to an associated plurality of connector members. A plug or receptacle is provided at the opposite end of the electrically conductive leads with respect to the end connected to the connector members. Securing means are provided for pressing the strands against the connector members interposed therebetween in order to insure a conductive connection between each strand and the conductive material of a connector member. The securing means can be provided in the form of a tubular member which is adapted to slide over the column of strands and interposed connector members. A wedge-shaped member can be inserted between an inside surface of the tubular member and one end of the column of strands in order to secure the tubular member to the column of strands and to press the column of strands and interposed contact members together.

Abstract: COIL END INSULATION FOR DYNAMOELECTRIC MACHINES A construction is provided for the stator coil ends of large dynamoelectric machines such as turbine generators of the gas inner-cooled type which effectively insulates the ends of the coils and mechanically reinforces them without interfering with ventilation. An insulating vent cap is applied over the ventilating tubes at each end of each conductor. The vent caps have a soft, uncured portion and are fitted to the conductor and then impregnated with a resin and cured in place to obtain a good fit of the cap on the conductor. The complete coil ends and connections are then covered with an insulating and mechanically reinforcing tape.

Abstract: 1516998 Stator cooling and winding insulation WESTINGHOUSE ELECTRIC CORP 15 Sept 1975 [25 Sept 1974] 37806/75 Heading H2A The stator winding of a dynamoelectric machine has a closed coolant system comprising a pump (28), Fig. 1 (not shown), a cooler (30), inlet and outlet manifolds (24), (25), hollow strands in the conductors 16 of the winding and headers 36 one at each end of each conductor 16, the epoxy resin impregnated mica tape insulation 46 on each conductor 16 terminating short of the headers 36 thereon, each conductor 16 in the regions adjacent headers 36 having its strands supported in relation to each other by epoxy resin (45), Fig. 4 (not shown), filling space between the strands (20), and the parts of each conductor 16 between its header 36 and insulation 46 each having a respective rigid electrically insulating support member 47 formed by layers of epoxy resin impregnated, non-woven, glass fibre material (48), Fig. 3 (not shown), each layer (48) forming a full sleeve-like covering of the conductor 16, layers (48) being interleaved with the mica tape layers (49), Fig. 3. A turbine driven generator, Fig. 1, has a gas-tight casing (13) filled with a coolant gas, e.g. hydrogen, to cool a hollow cylindrical stator (10) and a rotor (18). Each support 47 is interleaved with the corresponding insulation 46 by winding them alternately onto conductor 16 to form a splice 50, the support 47 being wound to gradually extend onto a tapered part of the header 36 and the insulation 46 then being impregnated with epoxy resin which is subsequently cured.

Abstract: 53,925 An improved method and apparatus for preventing electrical shorts between sets of stator coil headers and accompanying connections is disclosed in which a reinforced, non-conducting cover is fitted over a pair of stator coil headers, or a stator coil header and an adjacent phase connector. Thereafter, the cavity formed by the fitted cover can be filled with an insulating, solidifying or polymerizing material or resin. Use of such an apparatus insulates the entire header apparatus and prevents any accidental shorting between sets of stator coil ends.

Abstract: An end turn support structure is disclosed which permits it to be constructed with varying, preselected coefficients of expansion along its length. This characteristic allows it to expand in a similar manner to the end turns which it supports. This structure also comprises conformable members and external support apparatus that provide a means for firmly attaching the end turns to the support structure and the support structure to the stator frame.

Abstract: W.E. 56,084 A wall structure for insulating the exterior surface of a high voltage coil having Roebeled windings is provided that comprises an inner insulating layer formed from a hardenable epoxy material for surrounding the coil and filling void spaces on the surface of the coil created by the Roebeled windings, a ground wall layer surrounding the inner layer for grounding the wall structure, and a semiconductive layer formed from a carbon filled epoxy material integrally molded around the outer surface of the inner insulating layer for reducing the electric stress across the insulating layer and in particular across any voids remaining after the insulative layer has been applied over the Roebeled windings on the exterior of the coil. The improved wall structure advantageously increases the lifespan of high voltage coils by reducing the electric stress across the inner moulding layer, thereby reducing the probability that damaging electric arcing will ever occur in any void spaces present in this layer.
