Definitions
- the invention relates to a circuit breaker for a gas-insulated high-voltage switchgear according to the preamble of patent claim 1.
- Such circuit breakers are well known and are used for operating voltages from about 100 kV and operating currents of about 600 A to 4000 A.
- three phases are arranged in a common Isoliergasraum, with the advantage that a comparatively compact, space-saving arrangement for the high-voltage switchgear arises.
- Sulfur hexafluoride (SF 6 ) which has particularly good insulating properties, is used in particular as the insulating gas.
- a generic circuit breaker is characterized in that at least one separating element is arranged in the region between the conductors in the switching chamber, so that by the at least one separating element, a pressure equalization between the separate regions is made possible, and that the resulting by switching action decomposition products substantially in those area remain in which they originated.
- decomposition products are caused by the high temperatures of the switching arcs, which affect the chemical composition of the insulating gas of the high-voltage switchgear.
- decomposition products of this kind can spread particularly well, since pressure fluctuations and movements in the insulating gas result due to the switching arc and the chemical decomposition.
- the at least one separating element according to the invention By means of the at least one separating element according to the invention, the possible directions of movement of such decomposition products, in particular also of individual particles, are prevented. The interaction of the decomposition products formed on arcs of a particular conductor with one of the other conductors is thus reduced.
- the separating element has recesses.
- the at least one separating element in a region around an imaginary line between those points on two adjacent conductors, arise at the switching arcs, recesses are avoided.
- Single figure is a sectional view through a switching chamber of a circuit breaker.
- the single FIGURE shows a schematic diagram in the form of a section through a switching chamber 12 of a circuit breaker 10, not shown, for a gas-insulated high-voltage switchgear.
- the sectional view shows a first 14, a second 16 and a third conductor 18, which have a circular cross section in this view.
- the switching chamber 12 is constructed substantially tubular, so that in this view, an annular cross-section can be seen.
- a first invention 20 and a second partition 22 is shown, which have approximately the shape of a circular section in this figure.
- the partitions 20, 22 are turned off in accordance with a jacket portion of a correspondingly cylindrical figure.
- the partitions 20, 22 are also arranged mirror-symmetrically to the second conductor 16 and configured comparably, so that in particular the first partition wall 20 is to be discussed below.
- the first partition wall 20 has an upper portion 30, wherein a first end of the upper portion 30 is connected to the switching chamber 12 and has two recesses 32. At the other end of the upper portion 30 includes a central region 34 which has no recesses and is located symmetrically to an imaginary connecting line between the first 14 and the second conductor 16. The extent of the central region 34 is selected so that possible decomposition products which arise in the region around the first conductor 14 could not reach the second conductor 16 or even the third conductor 18 along an imaginary straight line. The propagation possibilities of decomposition products are thus considerably limited and can only reach their location in the direction of the recess 32 in other areas with a substantial straight line. All other decomposition products initially remain in the area in which they originated.
- a lower portion 36 which also has two recesses 32 and correspondingly has, for symmetry with the upper portion 30, a first end which is connected to the switching chamber 12 and has a second end which communicates with the central portion 34 ,
- the partitions 20, 22 are made of a non-conductive material, for example of a ceramic.
- a partition according to the invention can also have no recesses. Then the areas are completely separated. As a result, the mutual Fluxing each circuit breaker pole avoided by an optionally complete encapsulation. In addition, only comparatively few or no extinguishing gases can then reach another area and remain in the area in which they were created, for example, by a switching arc.
- the partition may also be realized by a corresponding embodiment of a circuit breaker itself, for example, by appropriate embodiments of an earth insulator and / or a chamber insulator of the switching chamber as insulating and the switching chamber as a metal body.
