The apparatus has a plurality of supports fixedly coupled to the platform at a back side of the platform and has a plurality of base supports fixedly coupled to the base. Two electrically insulating support elements, each secured in a fixed position on a support, extend obliquely downward from each support in a divergent manner and are each connected to one of two directly adjacent base supports. Two electrically insulating support elements, which are each fixed in a fixed position on the base support, extend obliquely upward from each base support in a divergent manner and are each connected to one of two directly adjacent supports, wherein each electrically insulating support element extends in the direction of its longitudinal extension from the fixed position of the support to the fixed position of the base support.
Background
As a "Flexible AC Transmission system" (FACTS), for example, a device for performing reactive power compensation is known. These devices have high-voltage devices which are set up in an electrically insulated manner in an open area by means of customary equipment. The apparatus has, for example, a 40m 2-sized platform on which the high-voltage device is arranged. The high-voltage device is connected to the high-voltage line and is at a high-voltage potential. In order to carry the platform in an insulated manner on the foundation embedded in the ground, supporting insulators are used which are manufactured from electrically insulating materials, including insulating materials which are customary in high-voltage technology, i.e. for example ceramics, plastics, fibre-reinforced plastics, etc. In order to extend the creepage path, the supporting insulator usually has external ribs, for example formed by a ceramic outer tube or a silicone coating.
In the device known from WO2013064167a1, a plurality of supports are fixedly connected to the platform at the rear side of the platform, wherein two supporting insulators, which are formed in one piece or in two pieces and are each fixed in a fixed position to a support, extend in a divergent manner obliquely downward from each support with respect to the vertical. The supporting insulators are each fastened to one of two adjacent base supports, which are fixedly connected to the base, when viewed vertically downward. Two supporting insulators, each connected to a fastening point of a base support, extend in a divergent manner obliquely to the vertical upwards from each base support, where they are each connected to one of two adjacent supports. Each supporting insulator thus extends in the direction of its longitudinal extension from a fixing position of the support to a fixing position of the base support.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to show increase earthquake load with relatively little expense.
The above-mentioned technical problem is solved by an apparatus for carrying a high-voltage device in an electrically insulating manner, having a platform on which the high-voltage device is arranged, the platform having a carrying structure for establishing the platform on a base in an electrically insulating manner, the carrying structure being formed by electrically insulating support elements. The apparatus has a plurality of supports fixedly coupled to the platform at a back side of the platform and has a plurality of base supports fixedly coupled to the base. Two electrically insulating support elements, each secured in a fixed position on a support, extend obliquely downward from each support in a divergent manner and are each connected to one of two directly adjacent base supports. Two electrically insulating support elements, which are each fixed in a fixed position on the base support, extend obliquely upward from each base support in a divergent manner and are each connected to one of two directly adjacent supports, wherein each electrically insulating support element extends in the direction of its longitudinal extension from the fixed position of the support to the fixed position of the base support.
The solution is to arrange a damping element, which acts in the direction of the longitudinal extent of the electrically insulating support element, between the fastening position of the support and the fastening position of the base support, which are connected to one another via the electrically insulating support element, respectively.
In particular, each seat is formed by two separate seat elements and each base support is formed by two separate base support elements, and one of the two fixing positions is located on each seat element and on each base support element, respectively.
Suitably, the two support elements of each support and the two base support elements of each base support are arranged in a spaced apart manner from each other.
According to a preferred embodiment of the invention, each support insulator extends from the support to the base in an inclined position.
According to a preferred embodiment of the invention, a resilient spring element is arranged in the damping element. The spring element may be an annular spring. The annular spring may be arranged in the hollow cylinder of the damping element.
Suitably, the number of abutments is equal to the number of base supports. In particular, four seats and four base supports are provided. This number has proven to be particularly advantageous since the weight of the supporting platforms customary in the high-voltage technology field, including the high-voltage devices arranged thereon, can be reliably borne by the eight supporting insulators thus formed, wherein at the same time the number of supporting insulators is significantly reduced compared to previously known devices.
In an advantageous manner, the supporting insulators are tensioned to one another by means of electrically insulating pull straps. The traction belt is made of, for example, glass fiber reinforced plastic. Which supports the load-bearing capacity of the load-bearing structure formed by the supporting insulator.
Suitably, the support insulator is provided with a retaining knuckle. For example, a common spherical joint is suitable as a retaining joint.
According to a preferred embodiment of the invention, the support structure is arranged centrally below the platform, wherein the support is in one plane and defines an area which is smaller than the area of the platform.

FIG. 3 shows a schematic view with a single supporting insulator and damping element according to FIG. 2, an

Detailed Description
Fig. 1 shows a device 1 with a flat and horizontally oriented platform 2. On top of the platform 2, high-voltage devices in the form of chokes 3, spark gaps 4, capacitor banks 5 and arresters 6 are arranged. During operation, the high voltage devices 3, 4, 5 and 6 are at a high voltage potential, for example 200 kV. The platform 2 is provided on its rear side with a bearing structure 12 for establishing the platform 2 on the base 9 in an electrically insulating manner and is formed by an electrically insulating support insulator 7, which is formed here in two parts each, with a connecting knuckle 8 in the middle and is provided with an outer rib.
Each support insulator 7 extends from the platform 2 obliquely downwards with respect to the vertical to a base 9, the base 9 being embedded in the ground. During operation, the entire weight of the high-voltage devices 3, 4, 5, 6 of the platform 2 is supported in a distributed manner on the supporting insulator 7, for which reason the supporting insulator 7 has a sufficiently high stability.
Fig. 2 shows the carrying structure 12 of the device 1. The carrying structure 12 here has eight supporting insulators 7. Each supporting insulator 7 extends between a support 13 and a base support 14. Each support 13 is connected to two support insulators 7, wherein the support insulators 7 connected to the same support 13 extend obliquely downward in a diverging manner to different base supports 14, i.e. obliquely with respect to the vertical when viewed vertically downward from the support 13 to the different base supports 14. In this case, the two supporting insulators 7 connected to the same carrier 13 are angled in a common plane, which is an acute angle in this case, with respect to the common carrier 13, wherein the common plane is slightly inclined at an angle of attack with respect to the horizontal. This applies correspondingly to the base support bodies 14 which are connected in each case to the two supporting insulators 7, which extend, viewed vertically upwards from the base support bodies 14, obliquely to the vertical to the two supports 13 arranged on both sides of the vertical, wherein the two supporting insulators open at an angle (here likewise an acute angle) with respect to the common base support body 14.
In fig. 2, the abutments 13 are arranged, for example, in a point-symmetrical manner with respect to one another and form the corners of an abutment rectangle. This applies correspondingly to the base support 14, the base support 14 also being able to be regarded as a corner of a base rectangle, wherein the base rectangle is rotated by 45 ° in plan view relative to the support rectangle. The carrier structure 12 is formed in a symmetrical manner as a whole and has a symmetry axis, not shown, which extends centrally vertically (perpendicularly) through the carrier structure 12.
The centre of gravity of the platform 2 is on the axis of symmetry of the load bearing structure 12. Since two support insulators 7 are respectively hinged to each support 13, even when one support insulator 7 breaks, the load of the platform 2 and the high-voltage devices 3, 4, 5, and 6 can be reliably received by the remaining support insulators 7.
Between the support 13 and the base support 14, a damping element 15 is arranged, which acts in the direction of the longitudinal extent 15a of the associated supporting insulator 7, the damping element 15 being fastened on the one hand to the support 13 and on the other hand to the supporting insulator 7.
Fig. 3 shows the embodiment according to fig. 2 by means of a schematic illustration with a single supporting insulator 7, which single supporting insulator 7 is here fixedly connected at its upper end to the lower end of the damping element 15. The upper end of the damping element 15 is fixed in a fixed position F of the support 13 by means of a hinge connection 16 in the form of a fork-shaped support 16a, the pivot 16b of which 16a extends perpendicularly to the plane of the drawing. Similarly, it is provided that the lower end of the supporting insulator 7 is fixed in a fixing position F of the base support 14 as a hinge connection 17 in the form of a fork support 17a, wherein the pivot 17b of the fork support 17a likewise extends perpendicularly to the plane of the drawing. In order to achieve damping, an annular spring 18 is present here, for example, in the hollow cylinder of the damping element 15.
In fig. 4, all the supports 13 are each formed by two separate support elements 13a spaced apart from one another, and all the base supports 14 are each formed by two separate base support elements 14a spaced apart from one another, wherein one of the two fastening positions F of the support 13 and the base support 14 is located on each support element 13a and each base support element 14a, respectively. In this embodiment, in each case two spaced-apart support elements 13a arranged at a distance from one another and two spaced-apart base support elements 14a each form a single base 13 and a single base support 14 (in terms of functional engineering), respectively, which are illustrated in fig. 4 by oval dashed lines. The two converging center lines of the two supporting insulators 7 respectively intersect or at least pass by a small distance past each other with the abutment element 13a and the base carrier element 14 a.
