Description
Technical field
The present invention relates to a kind of TRT part, more specifically, it relates to a kind of collector ring.
Background technology
The structure of existing collector ring has two kinds：A kind of collector ring for being to be installed with copper ring and asphalt mixtures modified by epoxy resin alicyclic ring composition；It is another
Planting is docked with half copper ring, middle plus insulating barrier, and the collector ring that underframe is assembled into is arranged at bottom；The wire outlet part of both collector rings
In its end, and center portion position outlet wherein is needed during other equipment combinations.Due to existing collector ring and other equipment assemblings
When limited by outlet position, can not find outlet method in the equipment assembling for not having center outlet position, or from center
During outlet, increase the practical operation difficulty of assembling.
At present, the Chinese patent of Patent No. CN102290696A discloses a kind of collector ring, and it is related to a kind of low tension
Device, is limited by outlet position when being to solve existing collector ring and other equipment assemblings and is designed, be specifically arranged to
Copper ring and resin pour the structure being integrated, and described collector ring one end is provided with step；The copper ring is internal from pouring with copper busbar
Portion is connected, copper busbar and disjunct copper ring middle setting insulating barrier, and copper busbar leading-out terminal is located at collector ring step lower surface；
The upper end surface at collector ring step end is provided with bolt.Outlet on the outside of the collector ring can be the slewing of non-stop layer outlet position
One rational outlet position is provided, makes not limited by outlet position when collector ring and other equipment assemblings.
But the collector ring used by wind-powered electricity generation place is adopted with the board-like and insulation tubular type that insulate, by slip ring and conducting rod at present
Assembling, the structure being bonded to one, and electric conduction rod component expose, and such version has following construction featuress and lacks
Fall into：
1. structure is thin, adds resin insulating barrier to do adhesive asserably between slip ring and axle sleeve；During the use of collector ring,
Axle sleeve drives slip ring to rotate by insulating barrier；Due to the weight of slip ring it is larger, start and brake process in the middle of can produce compared with
Big the moment of inertia, and this moment of inertia can directly act on insulating barrier, cause the shearing force to insulating barrier, if bonding feelings herein
Condition is bad or isolation layer intensity is inadequate, and this shearing force will destroy the bonding of insulating barrier, or directly destroy insulating barrier, causes to slide
Ring departs from the failure that overall structure and slip ring are struck sparks over the ground.
2. in the working environment of collector ring, due to the abrasion of carbon brush, carbon ash can be flown upward everywhere, and be possible to be attached to product
Any position of product；My company finds that in conventional maintenance process the current collection ring surface of long-term work can all adhere to one layer leads
The carbon dust of electricity；Simultaneously because operating ambient temperature higher (usual operating temperature is 40-120 DEG C), such ambient temperature can add
The aging of fast binding agent, softening are ftractureed；Alternate or sparking relatively is had when crackle of the carbon dust into insulating barrier just
Risk, can burn collector ring when serious；
3rd, in the course of work of collector ring, the connection of slip ring and conducting rod is equally very crucial；It is big that electromotor sends
Electric current is by conducting rod, then conducts to slip ring；Common failure is as between conducting rod and slip ring, contact area is inadequate so that
It is inadequate by the ability of high current in this link, cause resistance higher；It is light then cause collector ring abnormal heating, it is heavy then can cause and beat
Fire or even collector ring burn.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of collector ring.
For achieving the above object, the present invention adopts the following technical scheme that, a kind of collector ring, including steel bushing, conducting rod, slip ring
And insulation board, the insulation board is bonded on slip ring and steel bushing, is also bonded with three ear sealing parts on the insulation board, and described three
Ear sealing part centre is provided with via, and the insulation board is provided with the through hole coordinated in via, and the conducting rod is provided with insulation
Pipe, constitutes electric conduction rod component with binding agent sealing between the conducting rod and insulation tube, and the electric conduction rod component passes through via, leads to
Hole and slip ring simultaneously use binding agent sealing.
As preferred, steel bushing insulation sleeve outside the steel bushing, is arranged with, the steel bushing insulation is placed on steel bushing bonding connection, institute
It is that hot cover process processing connects that steel bushing is stated in steel bushing insulation sleeve.
As preferred, the electric conduction rod component and slip ring interference fit cold-pressing assembly.
Used as preferred, the surface of the steel bushing is bonded with car anti-rotation groove.
Hinge structure of the present invention is compared to be had：Greatly reduce because carbon dust attachment, ageing of binders cause it is exhausted
Edge hydraulic performance decline, causes alternate or sparking relatively, the possibility for turning on, burning；Improve the globality of product so that this collection
Electric ring product is greatly improved because overcoming the rotary inertia of slip ring, the ability of required opposing shearing force.
