Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, a magnetic pole connection structure of a high-speed pumped storage unit, which includes a U-shaped connector, the U-shaped connector includes a hard copper connecting piece 3 on both sides and a middle one for connecting two hard copper connecting pieces 3 The soft connecting piece 4, the hard copper connecting pieces 3 on both sides of the U-shaped connecting piece are respectively connected to the adjacent magnetic pole lead-out wires 1 of the generator motor in the pumped storage unit.

[0019] The U-shaped connector of the present invention is provided with a concave chute 2 corresponding to the bottom of the yoke. The concave chute 2 is parallel to the transverse axis of the U-shaped connector and is arranged horizontally. The hard copper connecting pieces 3 on both sides of the U-shaped connector The bottom is c...

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.

Description

technical field [0001] The invention relates to the field of pumped energy storage, in particular to a magnetic pole connection method of a generator motor in a pumped energy storage unit, in particular to a magnetic pole connection structure of a high-speed pumped energy storage unit. Background technique [0002] At present, with the rapid development of the pumped storage industry, more and more high-speed pumped storage units are put into production. In the existing high-speed pumped storage units, the magnetic pole connection of the generator motor generally adopts a U-shaped hard connection structure directly. There is an unavoidable problem in this connection method, that is, after the unit has been running for a long time, the U-shaped connection is easy to be strained and burned, thereby causing an accident of the unit. Contents of the invention [0003] The object of the present invention is to propose a magnetic pole connection structure of a high-speed pum...
