Description
Technical Field
The utility model relates to a be adapted to shorter copper ring pin support structure of stator core yoke portion.
Background
Traditional hydraulic generator copper ring lead wire support generally welds on stator core tooth clamp plate, various spare parts need to be arranged to hydraulic generator stator core tooth clamp plate top, like end hoop support and stator core penetrating screw rod and nut etc. to the unit of stator core yoke portion broad, can arrange above spare part and copper ring lead wire support above stator core tooth clamp plate top simultaneously, and to the shorter unit of stator core yoke portion, can not arrange all spare parts simultaneously on the tooth clamp plate, copper ring lead wire support needs to look for the position in addition. Due to space limitation, the copper ring lead wire support needs to span a stator core tooth pressing plate and a stator base in the radial direction, the tooth pressing plate of a common core in the axial direction is higher than the stator base, and the stator core and the stator base are inconsistent in thermal expansion rate, so that a steel base plate of the copper ring lead wire support cannot be welded with the stator core and the stator base at the same time and can only be welded with the tooth pressing plate at one end, the steel base plate forms a stress piece of a cantilever beam structure, a supporting bolt is closed at the other end of the steel base plate and is propped against a stator base ring plate so as to reduce the stress of a welding seam of the steel base plate and the stator core tooth pressing plate, and meanwhile, the supporting bolt and the stator base ring plate are in a free state in the radial direction and do not influence the thermal expansion.
Disclosure of Invention
In view of this, the utility model discloses a copper ring lead wire support structure who is adapted to stator core yoke portion is shorter has characteristics such as simple structure is stable, save stator core yoke portion space. The technical scheme is as follows: the insulation support is composed of a steel backing plate (1), insulation cushion blocks (2), insulation wire clamps (3), insulation screw rods (4), tightening nuts (5), steel pressing plates (6), supporting bolts (7), locking nuts (8), stator core tooth pressing plates (9) and stator base ring plates (10), wherein the steel backing plate (1) is welded on the stator core tooth pressing plates (9), the number of the insulation cushion blocks (2) is two, one insulation cushion block is arranged above the steel backing plate (1), the other insulation cushion block is arranged below the steel pressing plate (6), the insulation wire clamps (3) are arranged between the two insulation cushion blocks (2), the steel pressing plate (6) is arranged at the uppermost part of the support, the insulation screw rods (4) penetrate through all the insulation wire clamps (3) and the insulation cushion blocks (2) and fix the tightening nuts on the steel backing plate (1), the tightening nuts (5) are fixed at the end parts of the insulation screw rods (4), one ends of the supporting bolts (7) are fixed in the steel backing plate (1), the other end of the stator is supported on a stator base ring plate (10) and is locked and fixed by a locking nut (8).
The insulating screw rod (4) is of a stainless steel screw rod surface hot-pressing F-level epoxy phenolic glass cloth structure.
Technical effects
Traditional hydraulic generator copper ring lead wire support generally welds on stator core tooth clamp plate, various spare parts need to be arranged to hydraulic generator stator core tooth clamp plate, if end hoop support and stator core lead screw and nut etc. to the unit of stator core yoke portion broad, can arrange above spare part and copper ring lead wire support above stator core tooth clamp plate simultaneously, and to the shorter unit of stator core yoke portion, can not arrange all spare parts simultaneously on the tooth clamp plate, the position needs to look for in addition to the copper ring lead wire support. Because of space limitation, the copper ring lead wire support needs to span a stator core tooth pressing plate and a stator base in the radial direction, the tooth pressing plate of a common core in the axial direction is higher than the stator base, and the expansion rates of the stator core and the stator base are inconsistent, so that a steel base plate of the copper ring lead wire support cannot be welded with the stator core and the stator base at the same time, and can only be welded with the tooth pressing plate at one end, so that the steel base plate forms a stress piece of a cantilever beam structure, a supporting bolt is closed at the other end of the steel base plate in consideration of the stress requirement of the steel base plate so as to be propped against the stator base, so that the stress of a welding seam of the steel base plate and the tooth pressing plate is reduced, meanwhile, the radial direction between the.
