Fig. 2 is the polycrystalline substance schematic diagram of the isolating transformer of the present invention,
Fig. 3 is the side portion structure schematic diagram of the isolating transformer of the present invention.
In the accompanying drawings, identical parts use identical reference.Accompanying drawing is not according to actual scaling.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The isolating transformer of the present invention is applicable to rail vehicle.Wherein, the lower section at rail vehicle is provided with auxiliary change
Stream cabinet.At least two spandrel girder 3 it is provided with side by side in auxiliary converter cabinet.Isolating transformer includes iron core 2, twines
The line bag 1 that is wound on iron core 2, for fixing line bag 1 and the fixture of iron core 2, and for transformation will be isolated
Device is overlapped on the bridge piece on spandrel girder 3.It is used for by being arranged on isolating transformer on spandrel girder 3 to reduce
The weight that the fixture of fixing isolating transformer is subjected to.
In one embodiment, as it is shown in figure 1, bridge piece is hanger 4, it is overlapped on spandrel girder 3.And
Make isolating transformer between two spandrel girders 3.So, both simplified the structure design of auxiliary converter cabinet,
In turn ensure that the installation requirements of isolating transformer, it is also possible to alleviate the weight of auxiliary converter cabinet, thus alleviate auxiliary
Converter cabinet effect weight on the rail vehicle.Additionally, even if fixture loosens, isolating transformer can also lead to
Cross hanger 4 to choose on spandrel girder 3, prevent isolating transformer from dropping in auxiliary converter cabinet, thus isolation is become
Depressor or auxiliary converter cabinet produce and damage.The material of hanger 4 can be alloy or rustless steel etc..It can pass through
The mode of welding is fixed on isolating transformer.During installation, hanger 4 is overlapped on spandrel girder 3.
More specifically, hanger 4 includes that the generally rectangular base plate of shape and two shapes the most substantially become square
The side plate of shape.Two side plates are separately fixed at the opposite sides of base plate, and become 90 with base plate..As such, it is possible to
Improve the intensity of hanger 4, thus improve the steadiness of isolating transformer.When hanger 4 is overlapped on spandrel girder 3
Time, the base plate of hanger 4 contacts with spandrel girder 3, and the side plate of hanger 4 is positioned at the top of base plate.
Additionally, for the steadiness improving isolating transformer further, at four edges of isolating transformer
It is respectively provided with a hanger 4.When isolating transformer is arranged in auxiliary converter cabinet, each hanger 4 all with hold
Weight beam 3 overlaps.And when hanger 4 is overlapped on spandrel girder 3, the base plate of hanger 4 should not protrude from load-bearing
Beam 3, to save installing space.
Preferably, hanger 4 is arranged on the top of isolating transformer.By so arranging, directly fixing isolation becomes
The top of depressor, convenient fixing isolating transformer, save trouble and labor.In one example, hanger 4 is direct
It is welded on the fixture being positioned at above iron core 2, to simplify the structure of isolating transformer.Further, hanger 4
Bearing of trend substantially vertical with the bearing of trend of iron core 2.That is, isolating transformer is being overlapped on spandrel girder 3
Time upper, spandrel girder 3 is positioned at the not homonymy of line bag 1 with iron core 2 part exposing line bag 1.As such, it is possible to it is anti-
Only make to produce between iron core 2 and auxiliary converter cabinet collision etc. when installing isolating transformer.Hanger 4 is arranged on
During the top of isolating transformer, the most significant end of hanger 4 should not protrude from line bag 1, in order to is overlapped by hanger 4
On spandrel girder 3.Certainly, bridge piece can also be hook, etc..
When the height of iron core 2 is relatively low, can arrange on hanger 4 that the base plate with hanger 4 is fixing to be connected and the most greatly
Cause vertical extension board.It is held within the fixture above iron core 2 making hanger 4 reach by will extend over plate
Required height.Or, fixture arranges upwardly extending extension, hanger 4 is fixed on extension,
Deng.It is of course also possible to arrange reinforcing plate in the relative both sides of extension board, etc..
Additionally, preferentially select fixture to be arranged on the top of isolating transformer, to reduce the shape of isolating transformer
The error impact on causing time fixing.In a specific embodiment, fixture is bolt.It is by wearing
Isolating transformer is fixed in the through hole of spandrel girder 3 and the through hole 7 of hanger 4.It is arranged such, simple in construction,
It is also prevented between hanger 4 and spandrel girder 3 producing simultaneously and rocks.
Additionally, as shown in Figures 2 and 3, for the ease of placing isolating transformer, isolating transformer is provided with
For supporting the support seat 5 of isolating transformer.In a specific embodiment, support seat 5 and include connecting plate
51, and the gripper shoe 52 that be connected fixing with connecting plate 51.One it is respectively provided with at the two ends of connecting plate 51
Angulation substantially 90 between fagging 52, and connecting plate 51 and gripper shoe 52..It is arranged such,
Simple in construction, and be also convenient for installing.
Specifically, connecting plate 51 can be fixed on the lower section of iron core 2.As such, it is possible to simplify isolation further
The structure of transformator, and when being overlapped on spandrel girder 3 by hanger 4, spandrel girder 3 and support seat 5 are positioned at
The not homonymy of line bag 1, thus conveniently connect up.It is of course also possible between two gripper shoes 52 side by side
It is provided with multiple connecting plate 51, to improve the steadiness supporting seat 5.
It addition, when being arranged on isolating transformer by support seat 5, gripper shoe 52 vertically extends,
And protrude from the bottom of isolating transformer.And preferentially selecting, the lower end of gripper shoe 52 protrudes from isolation transformation
Device 4mm-6mm, to save installing space.Further, the upper end of gripper shoe 52 protrudes from connecting plate 51,
And fixing with hanger 4 is connected, with raising gripper shoe 52 and the firmness of hanger 4 further.Certainly, support
Plate 52 and hanger 4 can also directly be connected by connecting rod, etc..
When the electric input interface of isolating transformer and electric output interface are set, both are separately positioned on transformation
The both sides of device.As such, it is possible to input cable is separated with output cable, consequently facilitating cabling.Specifically, as
Shown in Fig. 2, cabling tubing string 6 can be set in the lower section of connecting plate 51, input cable and output cable are all provided with
Put in cabling tubing string 6.When being provided with multiple connecting plate 51, cabling tubing string 6 is arranged in bottom
On connecting plate 51, and the bottom of cabling tubing string 6 should not protrude from isolating transformer and the bottom of gripper shoe 52.
Although by reference to preferred embodiment, invention has been described, but without departing from the scope of the present invention
In the case of, it can be carried out various improvement and parts therein can be replaced with equivalent.Especially, only
Otherwise there is structural hazard, the every technical characteristic being previously mentioned in each embodiment all can combine in any way
Come.The invention is not limited in specific embodiment disclosed herein, but include falling within the scope of the appended claims
All technical schemes.
