Description
The present invention relates to a kind of active parts for electric high-voltage equipment, have magnetizable core, at least one
The winding for being used to generate magnetic flux in the core being retained on the core, and connecting line is had, the connecting line difference
It connect on the winding overhang of connecting line with winding and is connect on the distributor end of connecting line with distributor.
This active parts is by known in practice to technical staff.Thus, for example railway transformer has active portion
Part is equipped with connecting line, for the winding of active parts suitably to be connect with external module.In general, connecting line is designed
The distributor of active parts is extended up to for cable and from corresponding winding tap.Connecting line setting is filled with insulation
Extend inside the container of fluid and in the top of winding.In order to be connected on distributor, all connection lines are in core yoke
Top be caught and connect here with distributor.
Known active parts has the drawback that, since connecting line is arranged in above winding, so the container is necessary
It designs to accommodate active parts with being taken up space very much.However, especially in railway operation, for the possible constructions of electrical equipment
Space is limited.
Therefore, the technical problem to be solved by the present invention is to, a kind of active parts starting the type is provided, it is compact,
It is light and at the same time easy installation.
Above-mentioned technical problem solves through the invention, i.e., the described core constitutes (the chamferring in other words) of at least one chamfered edge
Core corner, and distributor is arranged in the region in core corner of the chamfered edge.
Active parts according to the invention has the core in the core corner with chamfered edge.Compared to known active parts,
The core corner of chamfered edge provides additional structure space for distributor.Therefore, it is arranged in above winding in other cases
Distributor can be arranged in the region in core corner of the chamfered edge, so that active parts according to the invention is designed more
It is compact and therefore can be arranged in smaller container.By active parts according to the invention and it is arranged on the active parts
The high-tension apparatus of container composition is therefore same more more compact than the high-tension apparatus according to the prior art and lighter.
Here, for example considering transformer or choke coil as electric high-voltage equipment.In particular, the electric high-voltage equipment
It is railway transformer, wherein the longitudinal direction of the winding of railway transformer extends in a horizontal plane in mounted position.In other words
It says, the winding of active parts is sleeping in a reservoir.Here, magnetizable material is interpreted as ferromagnetic material, such as iron.
Advantageously, core constitutes top and lower part yoke and at least one external core arm, the core arm
In extending between the yoke of lower part for the top, wherein the common structure of yoke of the core arm of all outsides and for example described top
At the core corner of chamfered edge.According to the prior art, external core arm and corresponding yoke piece are at rectangle in a cross section view
The corner of design.According to the present invention, which is chamfered and chamfers in other words, wherein lateral surface and outside by chamfered edge in yoke
Core arm between constitute such as two interior angles in a cross section view, rather than one 90 degree of interior angle.Thus, for example top
The intersection point on yoke and the chamfered edge portion extended straight the top common relative to them constitutes 135 degree of interior angle in a cross section view,
Wherein, the exterior contour of the chamfered edge portion and core arm equally constitutes 135 degree relative to their intersection point in a cross section view
Angle.Additional structure space is provided in the top in the chamfered edge portion, which is used for winding according to the present invention and connects
It connects.
According to this suitable improved design project is arranged, there are two external core arms.In this Variant Design scheme,
Two or four additional installation spaces are provided, distributor is enabled to be distributed on two four additional peaces in other words
Dress is spatially.Therefore, distributor is for example made of the two parts for being associated with winding arrangement respectively.The winding arrangement for example including
Two windings being coaxially arranged, a core arm in the core arm of multiple outsides extend through the two windings.
Preferred design scheme according to the invention, the core arm of all outsides are all coaxially surrounded by two windings.With
This mode provides the transformer without the feedback arm without winding.However unlike this, it also may be implemented according to the present invention
, there are two the cores of external feedback arm for structural belt, wherein in the connection between the yoke of lower part of feedback arm and top
Portion is at least difference chamfered edge at the yoke on top, to reconstruct the structure space for distributor.
Preferred design scheme according to the invention, connecting wire are designed as the round wire of insulation, have internal electricity
Line, the electric wire are surrounded by external cable insulating device.The cable insulating device guarantees the higher breakdown strength of connection line,
Connection line is disposed relative near the circle line of corresponding windings.Round wire according to the present invention, as insulation
Cable can be considered.
Preferred design scheme according to the invention, connecting wire is in external winding away from all adjacent windings
Extend on lateral surface.Therefore, be advantageously improved design according to this, connecting line no longer extends in the top of winding, to avoid to
The demand of additional internal volume in container.In this Variant Design of the invention, connecting line is from the outside for being arranged in winding
Winding joint on face sets out described in the winding on the lateral surface of every other winding along extension.According to the present invention,
The core corner for constructing chamfered edge together with corresponding yoke on the lateral surface is at least partly arranged around the core corner
There is dispenser unit.If active parts is for example equipped there are two winding arrangement, the winding of all outsides of winding arrangement all has
There is the side towards other parallel winding arrangements.However in addition, winding arrangement also constitutes the side away from other winding arrangements,
The side is referred to herein as winding or winding arrangement lateral surface.Connecting line is on the lateral surface along being led directly to point
With device, it is avoided by so that cable that is expending and occupying much room collects.The connector portions of winding are equally arranged in the outside
On face.
Other design scheme according to the invention, the magnetizable plate that core is mutually reclined by face formula are constituted.Institute
The iron plate that plate is preferably mutually insulated is stated, to reduce eddy-current loss.
Other expedients scheme according to the invention, distributor are configured to distribution plate, extend longitudinally,
In, which has multiple cable connecting pins being adjacently positioned connecting respectively with the distributor end of connecting line.Distribution plate
Extended with adapting to the length of the structure space provided by the corner being chamfered, enables distribution plate in the area in the corner of chamfered edge
It is mounted on active parts in domain.Distribution plate realizes the specific connection of active parts.
According to the suitable Curve guide impeller to this, cable connection end on its side away from connecting line respectively electrically with
Busbar connector connection, the busbar connector are connect on the end of distribution plate with lead system busbar connector.Here, lead system
The wall of a container on earth potential is advantageously passed through, which arranges in this embodiment.Active portion is realized in this way
