Description
Technical field
The present invention relates to a kind of for being connected to the electric device of high voltage power supply, which has magnetizable iron
Core, at least one be maintained on iron core designed in the core generate magnetic flux winding, can be filled with dielectric fluid
Cabinet, arranges cored and each winding and at least one hold-down frame in the cabinet, hold-down frame setting for by
Yoke bolt presses iron core.
Background technique
Those skilled in the art's this electric device known from practice.Previously known electric device is that railway becomes
Depressor can be fixed on rail guided vehicles.Railway transformer has active parts, and the active parts is by magnetizable iron
Core and two winding element compositions, winding element are respectively provided with armature winding and secondary windings.Armature winding and secondary windings
The stem of iron core is concentrically arranged and surrounded each other, which extends between upper yoke and lower yoke.Iron core is by flat against one another
The iron plate composition to recline, iron plate are mutually compressed by upper hold-down frame and lower hold-down frame.
On the longitudinal direction of winding, winding is arranged horizontally in cabinet, and is fixed by independent cabinet fixing piece
In the bottom of box.For this purpose, the outer profile that lower hold-down frame extends beyond iron core enters fixes sleeve, the fixes sleeve be welded on
Cabinet fixing piece connection on the bottom of box.
Due to additional component and extended hold-down frame, additional cabinet fixing piece be it is expensive and be thus it is high at
This.
Summary of the invention
Therefore, the technical problem to be solved by the present invention is to, a kind of electric device of type being initially mentioned is provided, it is active
Component can be quickly and inexpensively fixed on cabinet.
The present invention solves the technical problem by the way that iron core is fixed on cabinet using yoke bolt.
A kind of electric device is provided according to the present invention, such as is embodied as transformer, especially railway transformer, or
It is embodied as choke coil, which has simple fixed between iron core and cabinet.According to the present invention, hold-down frame is logical
The yoke bolt for being often only used for clamping iron core plate is also used for for iron core being fixed on cabinet.
Yoke bolt can be arbitrarily designed in principle in the scope of the invention.In preferred implementation of the invention, yoke
Bolt is designed as cylinder, and is equipped with external screw thread two ends.Here, being provided with through-hole in the core, yoke bolt extends
Across the through-hole.Corresponding through-hole is also disposed in two compression beams of each hold-down frame, and described two compression beams are preferably
It is opposite each other at upper yoke or lower yoke, wherein corresponding yoke is arranged between two compression beams.Yoke bolt had both extended through accordingly
Yoke, and extend through two compression beams of hold-down frame.The plate of iron core can mutually be clamped by screwing on nut.
Within the scope of this invention, the yoke bolt also extends into the fixation device being fixedly connected with cabinet.This is fixed
Device may be embodied as the simple thread plate on box body wall.The free end of yoke bolt twist-on in thread plate.Certainly, yoke
Bolt can also have multiple nuts or accordingly can twist-on retainer or component.For instance it can be possible that hold-down frame does not have
Have and be located on cabinet, but be provided with intermediate nut, the intermediate nut to a certain distance of the bottom of box to keep compressing frame
Frame, and therefore keep entire iron core.
Preferably, within the scope of this invention, fixed device is the fixes sleeve being fixed on inside the bottom of box.Fixing sleeve
Cylinder is protruded from the bottom of box, and for example equipped with internal screw thread, which engages with the external screw thread of one of yoke bolt.
Expediently, board group that iron core is reclined by flat against one another, magnetizable is at these plates are mutually pressed by hold-down frame
Tightly.It is known on this implementation principle of iron core, to not need that further implementation is discussed thus in this regard.It " can magnetic
Change " material is interpreted as ferromagnetic material herein.
In principle, yoke bolt can use two end and is fixed on cabinet by fixed device.For example, opposite each other
Body side can be by yoke bolt guide to being for example welded in the fixes sleeve on box body wall.However in the scope of the present invention
In, cabinet preferably has cabinet pond and the Box Cover with the close connection of cabinet pond liquid, wherein only cabinet pond by yoke bolt with
Iron core connection.According to the advantageous extension, Box Cover is only secured on cabinet pond.It in this way can preferably seal box
Body.Leakage is avoided by this way and method.
Expediently, iron core has at least one core mandrel, surrounded by least one winding, wherein each core mandrel
It by lower yoke and upper yoke and another core mandrel or returns and draws stem and connect, this time is drawn stem and do not surrounded by winding.In this hair
In the range of the bright extension can with otherwise the multiple core mandrels of setting, these core mandrels are respectively by one or more winding packets
It encloses.Different from this, a core mandrel can also be only set, connect with upper yoke and lower yoke.May be used also within the scope of this invention
Draw stem with completely left out time.
However, being different from this, two times can also be arranged and draw stem, do not surrounded by winding and be merely provided for closing
The magnetic circuit or iron ring of conjunction.Importantly, iron core has lower yoke and upper yoke, wherein by least one in this implementation of the invention
At least one core mandrel that winding surrounds extends between upper yoke and lower yoke.
Here, upper yoke and lower yoke are respectively equipped with hold-down frame.Hold-down frame is collectively responsible for keeping the plate of core mandrel
It is pressed against each other.Within the scope of this invention, it now is possible to using the yoke bolt of the yoke bolt of upper yoke and lower yoke come by iron core or by
The entire active parts of winding and iron core composition is fixed on cabinet.However within the scope of this invention differently, cabinet can also
To be connect at only one yoke, such as at upper yoke with cabinet.
Advantageously, electric device is railway transformer, and wherein for iron core tool there are two stem, stem is same each other by two respectively
The winding of center arrangement surrounds.Core mandrel and the winding for thus surrounding core mandrel are parallel to each other in a longitudinal direction respectively
Ground extends, and wherein they are horizontally extended.In other words, winding is located in cabinet.
Advantageously, cabinet is equipped with for by cabinet and therefore by the fixed company on the rail vehicle of entire electric device
Connection device.Rail vehicle is, for example, electrically driven (operated) locomotive or towing vehicle.
Detailed description of the invention
Of the invention other advantageous design scheme and advantage be referring to attached drawing to the embodiment of the present invention carry out with
The content of description afterwards, wherein identical appended drawing reference indicates the component of phase same-action, and wherein
Fig. 1 shows fixation of the active parts on the cabinet of electric device according to prior art, and
