Abstract
Provided is a magnetic pole connection structure of a high-speed pumped-storage unit, comprising a U-shaped connecting piece. The U-shaped connecting piece comprises hard copper connecting sheets (3) on two sides, and a soft connecting piece (4) which is used to connect the two hard copper connecting sheets (3) and is on the middle. The hard copper connecting sheets (3) on the two sides of the U-shaped connecting piece are respectively connected with adjacent magnetic pole leading-out wires (1) of a generator motor in the pumped-storage unit. The magnetic pole connection structure of a high-speed pumped-storage unit uses clever U-shaped soft connection and a sliding groove radial fixing method on design for realizing magnetic pole connection. On the premise of realizing a through-flow function of the magnetic pole connecting wires, a phenomenon that U-shaped hard connection easily strains is prevented, and a problem that the strength of the U-shaped soft connection is not enough is solved, and meanwhile U-shaped connection and fixation is enhanced, and hidden trouble that the U-shaped connection is thrown out is eliminated.

Summary of the invention
The object of the invention is, for the problem of easily pulling scaling loss initiation unit failure existing for the magnetic pole employing U-shaped Hard link structure of generator motor, to propose a kind of magnetic pole syndeton of high speed pump-storage generator.It has employed U-shaped cleverly and is flexible coupling and the radial fixed form of chute in the design realizing magnetic pole connection, under the prerequisite realizing the through-flow function of magnetic-pole connection wire itself, evade U-shaped Hard link and easily pull phenomenon, dissolve again U-shaped to be flexible coupling the problem of undercapacity, also strengthen U-shaped to be connected and fixed simultaneously, eliminate U-shaped connection and throw away hidden danger.
Technical scheme of the present invention is:
A kind of magnetic pole syndeton of high speed pump-storage generator, it comprises U-shaped connector, this U-shaped connector comprises the hard copper brace being positioned at both sides and the flexible link for connecting two hard copper braces being positioned at centre, and the hard copper brace of described U-shaped connector both sides is connected with the adjacent pole lead-out wire of generator motor in pump-storage generator respectively.
Flexible link of the present invention is the soft copper connection cord of arc soft copper sheet or embowment, and the crowning of arc axially upward.
The end of hard copper brace of the present invention and the end of magnetic pole lead-out wire are equipped with connecting hole, are bolted connection in connection hole.
Spill chute is provided with bottom the corresponding yoke of U-shaped connector of the present invention, spill chute is parallel with the transverse axis of U-shaped connector, equal horizontal arrangement, be connected by standing screw with spill chute bottom the hard copper brace of U-shaped connector both sides, standing screw can move along notch horizontal tangential in the sliding end of spill chute.
The connecting lever place of hard copper brace of the present invention offers fixing hole, and one end of standing screw is fixed on the fixing hole at hard copper brace connecting lever place, and the other end embeds in spill chute.
Hard copper brace of the present invention is that common magnetic pole connects hard copper sheet.
