Problems solved by technology

If the friction force between the stator cores is not enough to bind the silicon steel sheets, the silicon steel sheets will move radially under the action of radial magnetic pull, which will cause the paint film between the silicon steel sheets and the insulation of the stator rods to wear out, causing the unit to short circuit and fail to work normally. even serious accidents

Abstract

The invention discloses a steam turbine generator stator core lamination pressing device. It is composed of workbench, oil cylinder, pressure head, upper and lower pressure tires, tie rod Ⅰ, tie rod Ⅱ, coupling sleeve, snap ring and positioning pin. The invention can increase the number of tie rods II and coupling sleeves to realize the segmented pressing height requirement of the stator core laminations; and realize the pressing of stator cores with different diameters by replacing the upper and lower press tires. The device has strong versatility, high pressure loading accuracy and convenient operation.

Description

technical field [0001] The invention relates to a lamination pressing device for stator iron core of a steam turbine generator. Background technique [0002] The stator core of the steam turbine generator set is the key component that constitutes the magnetic flux circuit of the motor and fixes the stator coil. In the working state, the stator core is affected by the rotating magnetic field, which produces a strong radial rotating alternating magnetic pull on the stator core, and at the same time, the unit has a large vibration. If the friction force between the stator cores is not enough to bind the silicon steel sheets, the silicon steel sheets will move radially under the action of radial magnetic pull, which will cause the paint film between the silicon steel sheets and the insulation of the stator rods to wear out, causing the unit to short circuit and fail to work normally. There may even be serious accidents. The height between the silicon steel sheets of the stator...
