Abstract: The gas-insulated high-voltage switchgear includes a contact arrangement that is enclosed in a housing (10) and has two arc contacts in a coaxial arrangement, namely a tulip contact (20) with a constriction and a contact pin (30), said contacts being movable relative to each other along an axis (A). The switchgear also includes two insulating nozzles (40, 50) which are held at a distance to each other in the axial direction. The first (40) of the two insulating nozzles has a first flow channel (41), which is led along the axis and which comprises a first constriction (42), and the second (50) has a second flow channel (51), which is led along the axis and which has a second constriction (52). In the switchgear, the tulip contact (20) is arranged in a first flow channel (41) outflow section (43) which is arranged downstream of the first constriction (42). The sum of the flow cross-sections (Ακ, Α
Σ ) of the constriction of the tulip contact (20) and of a third constriction arranged in the outflow section (43) is greater than the flow cross-section (A
n ) of the first constriction (42), wherein a first sub-flow (L
11 ) of a quenching gas flow (L
1 ) can be conducted through the constriction of the tulip contact (20), and a second sub-flow (L
12 ) which is oriented parallel to the first sub-flow (L
11 ) can be conducted through the third constriction. In this manner, the dielectric restoration of an isolating gap which can be found in the arc zone (L) is improved upstream of the tulip contact (20), and the breaking capacity and the operating reliability of the switchgear are thus increased.Abstract translation: 气体绝缘高压开关设备包括一个封闭在壳体(10)中并且具有同轴布置的两个电弧触点的触点装置,即具有收缩部和触针(30)的郁金香触头(20),所述触点装置 触点可以沿轴线(A)相对于彼此移动。 开关装置还包括沿轴向彼此保持一定距离的两个绝缘喷嘴(40,50)。 两个绝缘喷嘴中的第一(40)具有沿着轴线引导并包括第一收缩部(42)的第一流动通道(41),并且第二流动通道(41)具有第二流动通道(51) 其沿轴线引导并且具有第二收缩部(52)。 在开关柜中,郁金香接触件(20)布置在布置在第一收缩部(42)下游的第一流动通道(41)流出部分(43)中。 郁金香接触件(20)的收缩部和布置在流出部分(43)中的第三收缩部的流动横截面(&Agr;&kgr;&Agr;&Sgr)的总和大于流动横截面 (42)的第一副流路(An),其中淬火气体流(L1)的第一子流(L11)可以通过所述郁金香接触件(20)的收缩部和第二子流路(L12) )平行于第一子流(L11)定向,可以通过第三收缩部进行。 以这种方式,在电弧区(L)中可以发现的隔离间隙的介电恢复改善了郁金香接触件(20)的上游,从而提高了开关柜的断路能力和操作可靠性。
