Abstract
The utility model discloses a megawatt level wind generator rotor lead wire structure, including electric motor rotor, lead wire, bearing housing and collecting ring, electric motor rotor circumference axial on the surface is provided with the lead -out groove, and the lead wire sets up in the lead -out groove, and the bearing housing cup joints on electric motor rotor, and the lead wire is connected with the collecting ring through connecting. The bend shaping and bend the connected mode by original 0.5mm 15=7.5mm thin copper sheet many times and change 9mm shaping copper bar segmentation copper bolt connection into of the adoption equipment of bending, the potential quality hidden danger because of bend and remain has many times thoroughly been eliminated to avoid thin copper sheet many times to bend fatigue phenomenon that the back appears, has stopped quality accidents such as the rotor lead wire burns out, generates heat, has guaranteed that the motor is in wind field reliability of operation to this fault rate that has reduced the motor.
Description
Technical field
This utility model MW class wind electrical generator fields, is specifically related to a kind of MW class wind and sends out megawatt
Level wind generator amature lead wire structure.
Background technology
In prior art, MW class wind generator amature lead wire structure mostly exists and is difficult to avoid that
Hidden danger of quality, such as: use 0.5 scale copper superposition composition, this structure at rotor lead wire and
Need to carry out repeatedly manual curved, because copper sheet nature causes repeatedly during the synthesis of collector ring binding post
There will be metal fatigue after curved and produce burr, wedge angle, and scale copper is at bending part copper sheet
There is gap between the two causes rotor lead wire insulating wrapping imprecision phenomenon insulating inner to be deposited
In cavity, when motor runs, there is big electric current on rotor lead wire copper sheet when rotor lead wire
The air continuous discharge of lead wire insulating inner cavity, this phenomenon can be caused when burr, wedge angle
Rotor lead wire local pyrexia final rotor windings ground connection, causing motor to run needs lower beam to return
Factory keeps in repair；Using conducting rod structure, damaging and nothing after damage easily occurs in this structure interface junction
It is long that method repairs procurement cycle again, and this structure thermal diffusivity is poor and draws with same insulation sectional area and connects
Line is compared and is allowed that the current-carrying that passes through is less the most easily occurs that rotor lead wire burns phenomenon.
Utility model content
This utility model purpose is to provide a kind of simple in construction, easily manufactured, it is possible to effective gram
Take the MW class wind generator amature lead wire structure of hidden danger of quality.
For realizing above-mentioned technical purpose, by the following technical solutions:
A kind of MW class wind generator amature lead wire structure, including rotor, lead wire,
Bearing holder (housing, cover) and collector ring, rotor circumferential surface is axially provided with lead-out groove, and lead wire sets
Being placed in lead-out groove, bearing holder (housing, cover) is socketed on rotor, and lead wire passes through joint and collector ring
Connect.
For making this utility model be more suitable for practicality, make further improvements below:
Described joint is c-type, and c-type is connected by screw one with collector ring upward, c-type
Down while being connected by screw two with lead wire.
Described screw two is at least four groups so that joint is able to fully with the contact area of lead wire
Ensure.
The surface area of one side down of described joint is more than collector ring binding post surface area.Make to draw and connect
The contact area of line and collector ring increases, and decreases rotor lead wire when motor runs with this
Fever phenomenon, i.e. increases conductivity and heat dispersion when motor runs.
Described lead wire is that molding copper bar is made.Can be according to rotor current size requirement by corresponding
Copper bar modification of dimension meets current-carrying capacity requirement.
The beneficial effects of the utility model are: this utility model simple in construction, easily manufactured,
Use bending equipment bending and molding and repeatedly rolled over by original 0.5mm*15=7.5mm scale copper
Curved connected mode changes 9mm molding copper bar segmentation brass bolt connected mode into, it is to avoid copper bar is repeatedly
The fatigue phenomenon occurred after bending, completely eliminates because of the remaining potential hidden danger of quality of repeatedly bending,
Stopped rotor lead wire burn, the quality accident such as heating, it is ensured that motor runs at wind field
Reliability, reduces the fault rate of motor with this.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Reference: 1-rotor, 2-collector ring, 3-bearing holder (housing, cover), 4-lead wire, 5-
Joint, 6-lead-out groove, 7-screw two, 8-screw one.
Detailed description of the invention
Embodiment
As described in Figure 1, a kind of MW class wind generator amature lead wire structure, turn including motor
Son 1, lead wire 4, bearing holder (housing, cover) 3 and collector ring 2, on rotor 1 circumferential surface axially
Being provided with lead-out groove 6, lead wire 4 is arranged in lead-out groove 6, and bearing holder (housing, cover) 3 is socketed on motor
On rotor 1, lead wire 4 is connected with collector ring 2 by joint 5.Described joint 5 is c-type,
C-type is upward while being connected by screw 1 with collector ring 2, and c-type is down and lead wire
4 are connected by screw 27.Described screw 27 is at least two groups so that joint 5 connects with drawing
The contact area of line 4 is fully ensured.The surface area of one side down of described joint 5 is more than collection
Electricity ring 2 binding post surface area.Lead wire 4 is increased with the contact area of collector ring 2, with
This decreases the fever phenomenon of the rotor lead wire 4 when motor runs, and i.e. increases motor and runs
Time conductivity and heat dispersion.Described lead wire 4 is made for molding copper bar.Can be according to rotor electricity
Stream size requirement meets current-carrying requirement by corresponding copper bar modification of dimension.Employing bending equipment is rolled over
Roll forming and changed into molding copper bar segmentation copper spiral shell by original scale copper repeatedly bending connected mode
Bolt connected mode, it is to avoid the fatigue phenomenon occurred after copper bar repeatedly bending, completely eliminates because of many
The potential hidden danger of quality that secondary bending is remaining, stopped rotor lead wire 4 burn, the quality such as heating
Accident, it is ensured that motor, in wind field reliability of operation, reduces the fault rate of motor with this.
