Abstract

The invention aims to provides a high-voltage unit stator winding inserting line machining process. The technical scheme includes that a high-voltage unit stator winding inserting line is composed of a main framework, a plurality of below-wedge filler strips, a groove lining, a plurality of interlayer thin filler strips, a plurality of anti-halation layers and a plurality of main insulating layers. A method of hanging a fine and soft steel wire of 6mm in diameter at a position, close to a notch, of a line rod, using a 0.5 or ton chain block for tensioning and using a wood rod to strike a steel wire rope to increase impact force is adopted, so that time for drawing the line rod is increased. An iron core is maintained while stator line rods are all replaced, new technology, new process, new material and film-reducing grounding main insulation are adopted for a stator line rod designing structure to improve heat radiation conditions of a motor. In order to improve electric strength of insulation, damage to insulation of the line rod is reduced, so that a pneumatic hydraulic inserting line machine is developed specially to complete the inserting line process better and more accurately. By the process, the line rod can be stably pushed into a groove to enable the line rod to be free of damage.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a high-voltage unit stator winding embedding process. Background technique [0002] In the past, due to the quality of assembly and manufacturing, single-phase grounding short-circuit accidents, iron cores and stator bars were burned, and the running time was reduced. Due to the tight time, short construction period, due to the unclean cleaning of the stator core, when the stator bar is off the line, the manual embedding method is used to hit the bar with a rubber hammer, which will inevitably cause damage to the insulation and reduce the electrical strength of the insulation. As a result, when the stator bar is subjected to an AC withstand voltage test, the insulation breakdown of the stator bar is caused, and a large amount of raw materials are wasted. Advanced embedding process method. Pulling the wire rods is a relatively large task in the dismantling work....
