Definitions
- the invention relates to a support device of an active part of a current transformer and a current transformer.
- active parts of current transformers are usually supported by two or four insulating supports, which take over the weight and the mechanical loads of the active part.
- the installation position is either suspended or upright.
- the invention has for its object to provide an improved support device of an active part of a current transformer and an improved current transformer.
- the object is achieved with respect to the support device by the features of claim 1 and Lich hinsieht- the current transformer by the features of claim 5.
- the support brackets are preferably chosen such that the Isolierstützbeine capture in a transport of the current transformer horizontal and / or lateral accelerations of the current transformer. As a result, the current transformer is Partly protected against transport damage that can be caused by such accelerations.
- An embodiment of the invention provides that the housing-side ends of each two insulating support legs have a greater distance from one another than the active-part-side ends of these insulating support legs.
- the insulating support legs spread from the active part to the housing bottom, so that they can accommodate particularly advantageous horizontal and / or lateral accelerations of the current transformer.
- Another embodiment of the invention provides exactly four insulating support legs.
- a current transformer according to the invention comprises a housing, an active part arranged in the housing and a supporting device according to the invention for supporting the active part with the advantages already mentioned above.
- a holder for housing-side fixing of the Isolierstützbeins is arranged on the housing bottom for each Isolierstützbein.
- the insulating support legs are advantageously in the housing, in particular to a
- the housing preferably has a lower housing part with the housing bottom and an upper housing part, wherein the lower housing part and the upper housing part are detachably connectable to each other.
- the single FIGURE shows a perspective view of a current transformer 1 with a housing 3, an active part 5 arranged in the housing 3 and a support device 7 for supporting the active part 5 in the housing 3, wherein the housing 3 is cut open on one side in the figure is.
- the support device 7 comprises four insulating support legs 71 made of an electrically insulating material, which carry the active part 5 and to be supported on a housing bottom 31 of the housing 3.
- the Isolierstützbeine 71 spread from the active part 5 to the housing bottom 31, so that a longitudinal axis of each Isolierst Reifenbeins 71 forms a non-vanishing support angle with the direction of gravity and the housing bottom ends of each two Isolierst Reifenbeine 71 have a greater distance from each other than the active part - side ends of this Insulating support legs 71.
- the support device 7 may have a different number of Isolierstützbeinen 71, for example, three or five insulating support legs 71.
- On housing bottom 31 is further for each Isolierstützbein 71, a holder 32 for housing bottom side fixing the Isolierstützbeins 71, for example by means of screw.
- the housing 3 has a housing lower part 33 with the
- the upper housing part 34 is dome-shaped and shown cut in the figure. At the top of the
- Upper housing part 34 two lifting lugs 37 are arranged for lifting the upper housing part 34 and the current transformer 1.
