The linear positioning support can be used for linear positioning in the main insulation cooling process of the hydroelectric stator bar, and the linear straightness of the stator bar is ensured. Through the tip structural feature of water and electricity stator bar, installation lead wire location support can be used to the lead wire space geometric dimensions location of water and electricity stator bar main insulation cooling process, prevents that the bar from causing the bar space geometric dimensions to change because of expend with heat and contract with cold in the cooling process.
Description
Technical Field
The utility model relates to a lap winding type hydroelectric stator bar cooling platform, in particular to the cooling and lead positioning of lap winding type hydroelectric stator bars.
Background
The main insulation of the hydroelectric stator bar needs to be cured by high temperature heating in a mould, and after the main insulation is cured by heating, the main insulation needs to be taken out of the mould and cooled at room temperature. If the stator bar is freely placed in the cooling process, the deformation of the stator bar can be caused by the expansion with heat and the contraction with cold of the material, so that the space geometric dimension deviation (mainly comprising space parameters such as rising, pitch, total length and the like) of the lead wire of the bar is caused, and the offline assembly effect is influenced.
Disclosure of Invention
In view of the above, the present invention aims to control the problem of distortion during the cooling process of an overwound hydroelectric stator bar, and is applicable to all overwound hydroelectric stator bars. The technical scheme of the utility model is as follows: by platform main part, sharp location support, tip support, lead wire location support, bolt, rectangle iron plate constitute, the platform main part passes through 10 sharp location supports of bolt fastening, and 8 tip supports of platform main part both sides welding respectively, the terminal welding rectangle iron plate of tip support, rectangle iron plate pass through 4 lead wire location supports of bolt fastening.
In above-mentioned lap wound formula water and electricity stator bar cooling platform, 2 spacing recesses of platform main part bilateral symmetry processing in length direction, spacing recess width and sharp location support match, 5 bolt holes of group are bored to spacing recess equidistance in length direction, and every group has 2 bolt hole symmetric distribution in spacing recess both sides, and is supporting with the bolt.
In the above-mentioned formula water and electricity stator bar cooling platform that folds, 2 bolt holes of 10 sharp location support bilateral symmetry brills match with the bolt hole on the platform main part recess, fix the fastening on the platform main part through the bolt.
In above-mentioned lap wound formula water and electricity stator bar cooling platform, 8 tip support front ends are evenly welded respectively in platform main part both sides, and the tip support equipartition of every side is in platform main part side, and the terminal welding rectangle iron plate of every tip support.
In the above-mentioned lap wound formula water and electricity stator bar cooling platform, the waist hole is processed on the rectangle iron plate, with the bolt supporting.
In the above-mentioned lap wound formula water and electricity stator bar cooling platform, 4 lead wire location supports pass through the bolt and lock with the rectangle iron plate.
The utility model has the beneficial effects that:
the cooling platform is applied to cooling and positioning of the main insulation of the stator bar after high-temperature solidification, the linear straightness of the stator bar in the cooling process can be ensured through the linear positioning tool on the cooling platform, and the geometric dimension of the lead space in the cooling process can be ensured not to change through the lead positioning tool on the cooling platform.

Detailed Description
As shown in figure 1, the lap winding type hydroelectric stator bar cooling platform comprises a platform main body 1, a linear positioning support 2, an end support 3, a lead positioning support 4, a bolt 5, a positioning groove 6 and a rectangular iron plate 7.
The platform main part 1 both sides weld multiunit tip support 3 respectively, and the terminal welding rectangle iron plate 7 of tip support simultaneously to installation lead wire location support 4 on rectangle iron plate 7, the line stick straight line is put the back well, and the lead wire freely falls on lead wire location support 4, fixes line stick lead wire spatial position, prevents that the tip of line stick in the cooling process from warping.
The working principle is as follows: according to the straight line of the stator bar and the lead wire space position, the positions of the straight line positioning support 2 and the lead wire positioning support 4 are properly adjusted, after the bar is disassembled, the bar is directly and linearly placed on the straight line positioning support 2, correspondingly, the lead wire is placed on the lead wire positioning support 4, and the bar is taken down after being cooled.
Because the utility model discloses the overlapping type hydroelectric stator bar cooling platform, after the bar is demoulded, the bar is linearly placed in the groove of the linear positioning support, and the straightness of the stator bar in the cooling process can be ensured. According to the spatial position of the lead wire of the coil, the end part bracket and the lead wire positioning tool are installed, and the lead wire part of the coil rod is placed in the groove of the lead wire positioning tool, so that the spatial geometric dimension of the lead wire in the cooling process can be ensured not to change.
The technical scope of the present invention is not limited to the contents described in the above description, and those skilled in the art can make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present invention, and these changes and modifications should fall within the scope of the present invention.
