Abstract

Cable suspension for a flexible high voltage cable in conjunction with a temporary high-voltage switch panel, the cable suspension consists of an insulator and an end closure and the button a the respective Schaltgeräteart carrying frame, characterized in that the cable suspension on Frame (4) of the high voltage switch panel (1) is arranged, wherein the frame (4) two as supports formed insulators (8), by means of a connecting element (9), the at least one terminal (10) for the end closure (11) of High voltage cable (6) includes, connected to the frame (4) Furthermore, a traverse (12) is arranged, the at least one Mounting clamp (13) for carries the high voltage cable (6), so that the end closure (11) between connecting element (9) and Traverse (12) is arranged fixed in position.

Description

The The invention relates to a cable suspension for a flexible high voltage cable in conjunction with a temporary high voltage switch panel, wherein this panel from a horizontally arranged base beams and formed vertically extending support beams Frame has, the basic carrier Crossbars include, where to adapt to the required Switching Device Configuration the respective switching device type (Circuit breaker, disconnector and converter) is arranged.

in the Framework of the training (New construction or repair) of high voltage panels of substations it is regularly required continue to supply certain overhead lines with it through them to maintain the electricity supply to important customers becomes. For this purpose, it is known provisional high-voltage panels set up next to the panels of the old system and the connection the example of 110 kV operated overhead lines to the panels over provisionally laid 110 kV high-voltage cable. These are the Cable on in addition to the panels to be built and thus freestanding auxiliary portal in the form of a bridge attached forming mast masts, by each one on the cross member of the Auxiliary porches arranged hanging isolator carries the end cap with the high voltage cable. To the stability to ensure the auxiliary portal this is braced laterally with guy ropes. The used Switch panels consist of a frame which is made horizontally arranged basic carriers and vertically extending support beams is formed, wherein the base support respectively include a crossbeam, where to adapt to the required Switching Device Configuration the respective switching device type (Circuit breaker, disconnector and converter) is arranged.

The Disadvantages of this solution consist in that by the loose suspension of the high voltage cables as well as the applied magnetic forces, the construction is not short-circuit proof and the auxiliary portals are very high need to do that to fulfillment the VDE regulations the live parts in a minimum height above the Earth are in addition to the impact distance to the support structure the auxiliary portal must be complied with. In addition, when using a second High voltage cable system also needed another auxiliary portal, which himself for a separate, freestanding auxiliary portal anyway required large space requirement even further increased.

The The object of the invention is to propose a cable suspension, which fully guarantees short-circuit safety, the VDE regulations in terms of minimum height and stroke met as well as simple and requires a small footprint.

These Task is in a generic cable suspension with solved the features specified in the characterizing part of claim 1 protection.

The Advantages of the invention are that by the mutual Fixation of the end caps the cable whose short-circuit proof clamping, the occurring dominated by magnetic forces, guaranteed can be. By integrating the cable suspension in the already towering Frame of the high-voltage panel can on freestanding auxiliary portals and their required Seilabspannung dispensed and yet the fulfillment of the VDE regulations regarding the minimum height of live conductors Parts over the soil and compliance with the impact distance to the support structure be secured. The solution still has a simple Construction on comes with a small footprint.

advantageous Further developments of the invention are evident from claims 2 to 4.

The Invention will be explained in more detail below with reference to an exemplary embodiment and associated drawings.

It demonstrate:

2 a side view according to the 1 the temporary high-voltage switch panel with the cable suspension according to the invention for a flexible high-voltage cable

In 1 is a temporary high-voltage switch panel 1 represented, which consists of horizontally arranged basic carriers 2 and vertically extending support beams 3 formed frame 4 having, wherein the basic carrier 2 crossbeams 5 include, where appropriate to adapt to the required switching device configuration, the respective switching device type (circuit breakers, disconnectors and converters) is arranged. Here is the cable suspension for the flexible high voltage cable 6 on the frame 4 of the control panel 1 arranged. These are after 2 on the frame 4 two trained as supports and each on a cross member 7 of the frame 4 arranged insulators 8th provided by means of a connecting element made of conductive material (eg aluminum) and designed as a rigid tube 9 , the at least one terminal 10 for the end closure 11 of the high voltage cable 6 includes, connected. On the frame 4 is still acting as a cable clamp rail Traverse 12 arranged, the at least one mounting clamp 13 for the high voltage cable 6 carries, so the end cap 11 between connecting element 9 and traverse 12 undergoes a position-fixed arrangement.
