Abstract
The utility model relates to the mechanical technology field, relates to a stator on a motor and especially relates to a heat dissipation stator punching sheet of a water wheel generator. The punching sheet comprises an arc sheet-shape body. An inner side of the body is provided with several skeletons which are convenient for winding a coil. The sheet-shape body is provided with heat dissipation holes. An outer side of the body is provided with several positioning grooves which are fixed to a stator shell. Top ends of the skeletons are provided with dovetail clamping grooves. The punching sheet has the advantages that heat dissipation is performed when the stator works so that a poor heat dissipation effect during long working time is avoided; the positioning grooves can realize circumferential fixation of the stator and a shell and connection is convenient.
Description
Technical field
The utility model relates to field of mechanical technique, about a kind of for the stator on motor, especially about a kind of heat radiation stator punching of hydraulic generator.
Background technology
During hydraulic generator, refer to take that the hydraulic turbine can be converted into the generator of electric energy by water as prime mover.During the current process hydraulic turbine, can convert water to mechanical energy, the rotating shaft of the hydraulic turbine drives again the rotor of generator, converts mechanical energy to electric energy and exports, and is the main dynamics equipment that hydroelectric station produces electric energy.
Stator is the actionless part of motor.Stator is comprised of stator core, stator winding and support three parts.The Main Function of stator is assembly line rod, line rod cutting magnetic line and then generation (output) electric current.Stator core is to be comprised of several stator punching stacks, and the stator punching of general motor is only the effect of playing fixed stator internal structure, but in some special fields, is obviously inadequate.Such as, when hydraulic generator is worked, because its power is larger, longevity of service, the temperature of generation is higher, and general stator module can not play good thermolysis, especially at stator after installation, Air Flow is few, it is particularly important that radiating effect seems.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of stator punching of rational in infrastructure, simple, good heat dissipation effect is provided.
For achieving the above object, the utility model has adopted following technical proposal: a kind of heat radiation stator punching of hydraulic generator, the sheet noumenon that comprises arc, described body inner side is provided with the skeleton that several are convenient to assemble coil, it is characterized in that, described sheet noumenon is provided with louvre, and body outside is provided with the fixing location notch of several and stator casing, and skeleton top is provided with dovetail draw-in groove.
In the heat radiation stator punching of above-mentioned a kind of hydraulic generator, described location notch is quadrangle, and take the center of sheet noumenon and be symmetrical arranged as symmetry axis.
In the heat radiation stator punching of above-mentioned a kind of hydraulic generator, the angle on described dovetail draw-in groove, location notch and skeleton is fillet.
Compared with prior art, the utility model has the advantage of: heat radiation during stator work, avoid its longevity of service to cause radiating effect bad; Location notch can be realized the circumferentially fixing of stator and housing, convenient connection.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of heat radiation stator punching of hydraulic generator, the sheet noumenon 1 that comprises arc, described body inner side is provided with several skeletons of being convenient to coiling 2, described sheet noumenon is provided with louvre 3, work process in, the heat of generation by louvre, can avoid working long hours after excess Temperature, body outside is provided with the fixing location notch 4 of several and stator casing, and skeleton top is provided with dovetail draw-in groove 5.
Described location notch is quadrangle, and take the center of sheet noumenon and be symmetrical arranged as symmetry axis.Angle on described dovetail draw-in groove, location notch and skeleton is fillet.Owing to will being wound around more coil on skeleton, angle is set to fillet, can avoid hurting coil.Location notch is symmetrical arranged by symmetry axis, is convenient to stator piece when work, stressed even, avoids stressed cause loosening of long-time one-way movement.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
