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

A magnetic pole connection structure for a high-speed pumped-storage unit, which includes a U-shaped connector, the U-shaped connector includes hard copper connecting pieces (3) on both sides and a middle one for connecting two hard copper connecting pieces (3) ), 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. The magnetic pole connection structure of the high-speed pumped water storage unit of the present invention adopts a clever U-shaped soft connection and a radial fixing method of the chute in the design of the magnetic pole connection. It eliminates the phenomenon that the U-shaped hard connection is easy to strain, and resolves the problem of insufficient strength of the U-shaped soft connection. At the same time, it also strengthens the U-shaped connection and eliminates the hidden danger of the U-shaped connection being thrown out.

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 operation. 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 pumped s...
