Abstract
The utility model relates to a rotor coil wire joint pipe structure for a double-water internal cooling generator which comprises a rotor coil and a rotor body groove of the generator. The rotor coil is inlaid in the rotor body groove. The utility model is characterized in that the both ends of a wire joint pipe are inlaid in the rotor body groove after being welded with the rotor coil, one end of a stainless steel connection is connected with the wire joint pipe by a formed circular hole on the wire joint pipe, and the other end is connected with a water tank 7 by an insulating water pipe. The utility model has the advantages that three welding parts of the stainless steel connection and the wire joint pipe as well as the wire joint pipe and the coil cannot be mutually influenced; the circular hole on the wire joint pipe used for welding is processed by a forming drill to ensure a welding interval, and ensure the welding quality. The birth of the wire joint pipe exempts the processing of the prior three-way joint to cause the optimized arrangement of a rotor end coil to be possible.
Description
Technical field
The utility model relates to a kind of dual internal water cooled generator rotor coil terminal tubular construction, can be used for the double water innercooling electric generator rotor, belongs to double water innercooling electric generator rotor technology field.
Background technology
Double water innercooling electric generator stator and rotor coil water flowing cooling, good cooling results, coil temperature rise is low, and insulation is reliable, and volume is little, has series of advantages.But most critical is the rotor coil that must guarantee high speed rotating, its water, is electrically connected reliablely, and seepage does not take place.
The early stage joint design of dual internal water cooled generator rotor coil be welded on the copper cash that has the oval hole, but this can not guarantee welded gaps after once the stainless steel turning being flattened.Also adopted the transition joint of two logical and threeways, too near because of the distance between each weld seam, several places all need welding, can influence each other between weld seam; Secondly, the three-way connection processed complex needs to forge, and the metalworking operation is many, also will detect a flaw, the cost height of wasting time and energy.And technology is dispersed big, causes quality problems easily.
Summary of the invention
The purpose of this utility model provides a kind of easily manufactured, stops seepage, the dual internal water cooled generator rotor coil terminal tubular construction that generator operation is safe and reliable.
For realizing above purpose, the technical solution of the utility model provides a kind of dual internal water cooled generator rotor coil terminal tubular construction, comprise rotor coil and generator amature body groove, rotor coil is embedded in the rotor-body slot, it is characterized in that, be embedded in the rotor-body slot after the two ends of terminal pipe and the rotor coil welding, stainless steel turning one end is connected by the moulding circular hole on it with the terminal pipe, and the other end is connected with water tank by the insulation aqueduct.
The utility model terminal pipe is equivalent to a three-way connection, and size big wall in middle part is thicker, and two ends and coil hollow copper wire are measure-alike, are the blind joint pipes that same mother metal draws out.Weld with coil respectively at the junction block two ends, and transition joint partly is used for processing with the moulding brill with the circular hole of stainless steel turning welding, can guarantee welded gaps.The birth of terminal pipe has fundamentally solved the seepy question of rotor turning welding point, has improved the double water innercooling electric generator reliability of operation.
The utility model has the advantages that, stainless steel turning and terminal pipe, and the welding of terminal pipe and coil three places can not influence each other; The circular hole that is used to weld on the terminal pipe bores processing with moulding, has guaranteed welded gaps, has guaranteed welding quality.Three-way connection processing has in the past been removed in the birth of terminal pipe from, makes the preferred arrangement of rotor tip coil just possible.

Fig. 1 is a kind of dual internal water cooled generator rotor coil terminal tubular construction schematic diagram;
Fig. 2 is a kind of dual internal water cooled generator rotor coil terminal tubular construction end view.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, 2, be a kind of dual internal water cooled generator rotor coil terminal tubular construction schematic diagram, described a kind of dual internal water cooled generator rotor coil terminal tubular construction is made up of terminal pipe 3, junction block moulding circular hole 4, stainless steel turning 5, braided steel wire insulation aqueduct 6.
Rotor coil 1 is embedded in the rotor-body slot 2, be embedded in the rotor-body slot 2 after the two ends of terminal pipe 3 and rotor coil 1 welding, realize being electrically connected between coil and the coil, terminal pipe 3 is by being connected with insulate aqueduct 6, water tank 7 of braided steel wire after the moulding circular hole 4 on it and 5 welding of stainless steel turning again, realize that rotor coil 1 is connected with the water of water tank 7, whole rotor water route is finally leaked through pump and is guaranteed ne-leakage, and double water innercooling electric generator is reliable.
