Abstract
The utility model relates to an end joint sleeve for assembling a stator coil of a 3MW permanent-magnetic synchronous wind driven generator. The end joint sleeve comprises a U-shaped sheet (1), the left top end and the right top end of the U-shaped sheet (1) are respectively scrolled outwards to form contact soldering terminals (2). According to the end joint sleeve for assembling the stator coil of the 3MW permanent-magnetic synchronous wind driven generator, the service life of the generator can be prolonged.
Description
Technical field
The utility model relates to a kind of and headgear, especially relates to a kind of also headgear of the 3MW of being used for permanent magnet synchronous wind generator stator coil assembling.
Background technology
Wind-driven generator is one of most important infrastructure device in the wind power generation, and its quality is directly connected to the operation of whole generating system; Wherein, stator coil is the important core parts in the wind-driven generator, and stator coil is embedded in the wire casing of stator core, need be connected between coil and the end ring; Conventional connected mode links to each other for the mode that adopts welding, and this class formation finds that in practical application quality of connection is not high, and the weld of head rupture easily, thereby influence useful life of generator.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can prolong generator the 3MW permanent magnet synchronous wind generator stator coil assembling usefulness and the headgear in useful life.
The purpose of the utility model be achieved in that the assembling of a kind of 3MW permanent magnet synchronous wind generator stator coil with and headgear, said and headgear includes the U-shaped sheet, the respectively outside turnup in the top, the left and right sides of said U-shaped sheet becomes the contact weld tabs.
Compared with prior art, the beneficial effect of the utility model is:
The utility model through and headgear after just the end of a thread is welded on the end ring, thereby connect more firmly, be not easy to take place fracture accident, thereby prolonged the useful life of generator.
Description of drawings
Fig. 1 is that the also structural representation of headgear is used in the assembling of the utility model 3MW permanent magnet synchronous wind generator stator coil.
Wherein:
U-shaped sheet 1, contact weld tabs 2.
Embodiment
Referring to Fig. 1, a kind of 3MW permanent magnet synchronous wind generator stator coil assembling that the utility model relates to is used and headgear, and said and headgear includes U-shaped sheet 1, and the respectively outside turnup in the top, the left and right sides of said U-shaped sheet 1 becomes contact weld tabs 2.
During welding, the lead-out wires of coil head is put into U-shaped sheet 1, then the both sides of U-shaped sheet 1 is clamped lead riser toward middle turnup, weld, then will and the contact weld tabs 2 of headgear be attached on the end ring, at last with scolder will and headgear be welded on the end ring firmly.
Claims (1)
1. a 3MW permanent magnet synchronous wind generator stator coil assembling is used and headgear, and it is characterized in that: said and headgear includes U-shaped sheet (1), and the respectively outside turnup in the top, the left and right sides of said U-shaped sheet (1) becomes contact weld tabs (2).
