Description
Technical field
The present invention relates to the end cap of wind-driven generator, specially a kind of combination of wind-driven generator insulated end cover.
Background technology
Wind driven generator insulating device now mainly uses insulation bearing or matched somebody with somebody without latitude tape insulation end cap and rotating shaft earthing brush
Conjunction is used.Install and run with the high-volume of wind-driven generator, the bearing galvanic corrosion phenomenon caused by shaft current is increasingly protruded.Study carefully
Its reason is mainly：Poor without latitude tape insulation end cap Hygrothermal Properties, water imbibition causes insulated end cover to fail more by force.Insulated end cover electric capacity
Value is too high, and capacity current is larger, or even breakdown.The capacitance of insulated end cover is reduced, reduces insulated end cover capacity current, it is ensured that
The insulation stability of insulated end cover, and the convenient insulated end cover for detecting shaft current size turns into the bottle of wind-powered electricity generation industry technological break-through
Neck.
The content of the invention
There is provided a kind of insulation of combination of wind-driven generator for the problem of present invention solves existing wind-driven generator end cap poor insulativity
End cap.
The present invention adopts the following technical scheme that realization：Combination of wind-driven generator insulated end cover, including end cap body and
Bearing chamber；Intrinsic insulation connection ring is covered between end cap body and bearing chamber, i.e. the inner ring surface of end cap body is socketed on insulation and connected
The outer ring surface of ring is connect, the inner ring surface of insulation connection ring is socketed on bearing chamber outer ring surface.Insulated end cover in bearing chamber in use, pacify
Fill bearing.Insulation terminal pad comes end cap with bearing chamber insulation, has blocked the path of shaft current, has thus achieved to shaft current
Insulation, effectively prevent the harm that shaft current is caused to motor.
Compared with the existing tape insulation end cap without latitude, combination of wind-driven generator insulated end cover of the present invention uses brand-new
Insulation system, insulation thickness is thicker, intensity is higher, capacitance is smaller, the low frequency shaft current that is not only produced in itself to motor and right
The high frequency shaft current produced by frequency converter has good insulation effect, is also greatly reduced insulated end cover capacity current.With public affairs
That knows needs several parts combination assemblings without latitude tape insulation end cap compared to the processes such as winding, baking, processing are eliminated, only,
Technique is simple, and the manufacturing cycle is short.The present invention can substitute existing without latitude tape insulation end cap completely, and properties are better than without latitude
Tape insulation end cap.

In figure：1- end cap bodies, 2- bearing chambers, 3- insulation connection rings, 4- adpting flanges, 5- gussets, 6- cover plates.
Embodiment
Combination of wind-driven generator insulated end cover, including end cap body 1 and bearing chamber 2；End cap body 1 and bearing chamber 2 it
Between cover intrinsic insulation connection ring 3, i.e. the inner ring surface of end cap body 1 is socketed on the outer ring surface of insulation connection ring 3, and insulate connection ring 3
Inner ring surface be socketed on the outer ring surface of bearing chamber 2.Bearing chamber 2 is in axial single-order scalariform, the end face outside and end cap of the connection ring 3 that insulate
The end face outside of body 1 and bearing chamber 2 is flush, and so ensure that insulation connection ring 3 can only be socketed on the big outer shroud of bearing chamber 2
On face（Axially there is large and small point in the outer ring surface of single stair-stepping bearing chamber）.To realize insulation connection ring 3 and end cap body 1
Set between bearing chamber 2 is consolidated, and the inner side end of insulation connection ring 3 is provided with adpting flange 4, the end face outside of adpting flange 4 with
The inner side end of end cap body 1 and the contact of the cascaded surface of the outer surface of bearing chamber 2（The outer surface of bearing chamber is by end face outside, interior
Side end face, outer ring surface and cascaded surface are constituted）, in phase between end cap body 1, bearing chamber 2 and the adpting flange 4 for the connection ring 3 that insulate
Twist solid with bolt at mutual contact surface；So set fixing structure is more reasonable, unique.Ring is evenly distributed in gusset on end cap body 1
5, it is to be fixed with cover plate 6 on the window of hollow out, window between adjacent webs 5.The setting of gusset 5 facilitates the measurement of shaft current, surveys
Clamped when amount shaft current with clamp meter（8）Gusset or one of them, measurement terminate after cover plate 6 is fixed on end cap window
And use sealant sealing.When it is implemented, end cap body 1, bearing chamber 2 are metal material, cover plate 6 is metal material or nonmetallic
Material, insulation connection ring 3 is the insulating materials for having enough rigidity and thickness, it is ensured that insulated end cover can bear wind-driven generator radially
Load and axial impact, such as rubber, phenol aldehyde glass fabric swatch, plastics, the various insulating materials of unsaturated-resin.
