Description
Technical field
The utility model relates to a kind of hydraulic generator unit rotor magnetic pole coil of improvement.
Background technology
Hydraulic generator unit capacity-increasing transformation unit rotor magnetic pole coil was because of on-line operation more than 30 years, and rotor magnetic pole coil lead-in wire root portion is blown, the overheated interpolar on line that causes that goes between fuses, and rotor open circuit is forced to accidental shutdown.Therefore need to carry out capacity-increasing transformation to overall hydraulic generator unit rotor magnetic pole coil.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic generator unit rotor magnetic pole coil of improvement.
The technical solution of the utility model is: the hydraulic generator unit rotor magnetic pole coil of this improvement has some pole coils, interpolar connecting line, magnetic pole lead-out wire, sunk screw, excitation winding, described excitation winding is by pole coil, interpolar connecting line, magnetic pole lead-out wire and sunk screw are connected together to form, described interpolar connecting line is by counterclockwise coiling on pole coil, described magnetic pole lead-out wire sunk screw to be fixed on pole coil and to draw, described interpolar connecting line and magnetic pole lead-out wire adopt the soft copper sheet that multilayer 0.5mm is thick to form, and its sectional area should be more than or equal to coil copper bar sectional area, and overlap 10 times that area is copper bar sectional area with copper bar.
Further, described soft copper sheet there is tin coating.
Further, described pole coil adopts heptagon copper bar and adopts F class F insulation.
Further, the bore size of described interpolar connecting line is consistent.
The beneficial effects of the utility model are: adopt some pole coil interpolar connecting lines to be connected with magnetic pole lead-out wire with excitation winding, and processing method be rotor coil through copper bar annealing, edge-wind, rotor coil double annealing, cold pressing, go between shaping, boring after, carrying out rotor coil lead-in wire connect, decrease original rotor magnetic pole coil to go between the extra current loss be connected with copper ring copper bar, the energy output that improve pole coil motor, reduce weight and the fatigue stress of integral rotor simultaneously, reach and saved motor cost, improve production efficiency.
