Abstract
The invention relates to the technical field of power generator stators and particularly relates to a novel protection device for an auxiliary power generation stator of a primary and auxiliary power generator. The novel protection device for the auxiliary power generation stator of the primary and auxiliary power generator comprises at least three fixing legs which are uniformly arrayed below a platform; an outer ring of the platform is a seam allowance and a lifting lug is arranged on the platform; and a through hole is formed in the lifting lug. When the novel protection device for the auxiliary power generation stator of the primary and auxiliary power generator is used, the auxiliary power generation stator of the primary and auxiliary power generator is arranged on the device and the fixing legs of the device are supported on the ground, so that conditions that a coil at a lower end of the auxiliary power generation stator of the primary and auxiliary power generator is stressed and deformed are prevented, and the integrity of the auxiliary power generation stator of the primary and auxiliary power generator is guaranteed.
Description
Technical field
The present invention relates to generator unit stator technical field, especially a kind of auxiliary stator protection dress of new main and backup generator
Put.
Background technology
During hxn5 locomotive 5gmg201e1 type main and backup generator disintegrates, need end cap is pulled down from stator, then will
Auxiliary stator is pulled down from end cap, and auxiliary stator is overhauled, but the special structure of auxiliary stator, determine for auxiliary during this
Sub- lower coil stress is serious, and by the screw on support and suspension ring during handling, and lower section directly lands for coil, auxiliary stator
Total weight be pressed on stator lower coil, easily make end-coil stress, deformation under auxiliary stator, there is hidden danger, when serious hold
Easily there is turn-to-turn short circuit, or even in operation, burning phenomenon occurs, improve the cost of overhaul, meanwhile, hxn5 locomotive 5gmg201e1 type master
One of auxiliary generator major failure be exactly accumulator winding in auxiliary stator, Exciting Windings for Transverse Differential Protection, stator blower fan winding occur circle short, burn
The fault such as damage, be also the big event of overhaul tackling key problem, the handling of auxiliary stator and to deposit the frequency more, the repair time increases, and increases
Add the impaired probability of coil.
Content of the invention
In order to overcome end-coil stress, deformation under existing auxiliary stator, there is hidden danger, be susceptible to turn-to-turn when serious short
There is the deficiency of burning phenomenon in road, or even operation, the invention provides a kind of auxiliary stator protection of new main and backup generator
Device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of auxiliary stator of new main and backup generator is prevented
Protection unit, is uniformly placed with least three fixing feet below its platform, described platform outer ring is seam, and described platform is provided with and hangs
Ear, described hanger is provided with through hole.
According to another embodiment of the invention, further include, the distance between bottom of described seam to upper edge is
5mm.
According to another embodiment of the invention, further include, described through hole is slotted eye.
According to another embodiment of the invention, further include, described platform is concentric circular platform, and platform is sky
The heart is justified, and this platform outside diameter is less than circular diameter in stator coil.
According to another embodiment of the invention, further include, the height of described fixing foot is more than stator lower end and line
Difference in height between circle.
The invention has the beneficial effects as follows, this auxiliary stator preventer of new main and backup generator when in use,
Auxiliary for an auxiliary generator stator is placed on this device, the fixing foot of this device supports on the ground, prevent auxiliary of auxiliary generator fixed
The coil of sub- lower end receive extruding cause coil stress, deformation situation occur it is ensured that auxiliary stator of auxiliary generator complete.
Brief description
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the top view of the present invention；
Fig. 3 is auxiliary stator sectional view of auxiliary generator of the present invention；
Fig. 4 is the use state figure of the present invention；
In figure 1, platform, 2, seam, 3, fixing foot, 4, hanger, 5, through hole, 6, coil, 7, stator.
Specific embodiment
If Fig. 1-4 is the structural representation of the present invention, a kind of auxiliary stator preventer of new main and backup generator, it is put down
Uniformly it is placed with least three fixing feet 3, described platform 1 outer ring is seam 2, described platform 1 is provided with hanger 4, institute below platform 1
State hanger 4 and be provided with through hole 5.
According to another embodiment of the invention, further include, the distance between bottom of described seam 2 to upper edge is
5mm.
According to another embodiment of the invention, further include, described through hole 5 is slotted eye.
According to another embodiment of the invention, further include, described platform 1 is concentric circular platform, and platform 1 is
Open circles, this platform 1 outside diameter is less than circular diameter in stator coil 6.
According to another embodiment of the invention, further include, the height of described fixing foot 3 be more than stator 7 lower end with
Difference in height between coil 6.
This auxiliary stator preventer of new main and backup generator is according to auxiliary stator of 5gmg201e1 type main and backup generator
Construction featuress, design the concentric circular platform 1 supporting with auxiliary stator lower end support size, this platform 1 is open circles, not only up to
To load bearing stength, alleviator weight simultaneously, platform 1 outside diameter is less than circular diameter in coil 6, platform 1 inner circle with diameter greater than
Support diameter of bore；The seam 2 designing 5mm in platform 1 Inner arc is mated with auxiliary stator 7, makes preventer and auxiliary stator 7
Connect more firm, the fixing foot 3 of symmetric design three below concentric circular platform 1, the height of fixing foot 3 is more than under auxiliary stator 7
End-coil 6 and the difference in height of support, force part when auxiliary stator 7 thus can be made to put, on stator 7 support, exists simultaneously
Stress platform 1 inner side increases by two hangers 4, and one is to make stator 7 be hung to play guide effect during preventer, and two is in hanger 4
On open slotted eye, passed through from hole using bolt and be fixed together with auxiliary stator 7, make the preventer can 7 sons fixed with auxiliary
Handling together, is carried out during maintenance on preventer, facilitates auxiliary stator coil, lead-out wire, the maintenance of collector ring.
Described above be merely exemplary for the purpose of the present invention, and nonrestrictive, those of ordinary skill in the art understand,
In the case of the spirit and scope being limited without departing from claims, many modifications, change or equivalent can be made, but all
To fall within the scope of protection of the present invention.
