Title
(EN) Sealed cable inlet through an external and an internal wall of a containment shell of a nuclear power station
(ZH) 穿过核电站安全壳外墙和内墙的密封电缆引入装置
Abstract
(EN) The invention relates to the field of electrical engineering, and specifically to sealed inlets of electrical circuits into a sealed area of a multi-layered containment shell of a nuclear power station. This design can be used in passages through an external and an internal wall which are subject to relative mutual displacement as a consequence of a seismic phenomenon or thermal expansion of the walls and passage. The problem addressed by the present invention is that of increasing the operating reliability of a sealed cable inlet when high-voltage electrical conductors which have little bending capacity are used. The problem addressed is achieved in that the sealed cable inlet through an external and an internal wall of a containment shell of a nuclear power station comprises an embedded pipe (3) which is arranged in the internal wall (1), with an inlet section (44) of a cable (2) fixed rigidly within said pipe. A means for compensating for a relative movement between the cable (2) and the external wall (11) is mounted in the external wall (11) coaxially with respect to the pipe (3). The compensating means has a tube (19) with a bellows (24) on the external end plane (20) and with a second analogous bellows (25) which is mounted symmetrically on the opposite end plane (21) of the tube (19) at the internal surface (18) of the external wall (11). The free ends (30) and (31) of the two bellows (24) and (25) are of conical design and have internal surfaces (28) and (29) which are support elements for an outlet section (46) of the cable (2), which is arranged freely in the tube (19) with a gap (47) relative to the internal surface (49) of the tube (19). The gap (47) between the braiding (48) along the external surface of the cable (2) and the internal surface (49) of the tube (19) is selected using a design calculation. The gap (47) must not be less than the value of maximum orthogonal thermo-seismic movement in one plane of the internal wall (1) relative to the external wall (11) and change in the coaxial position of the cable (2) in the tube (19).
(ZH) 本发明涉及电气工程领域,尤其涉及一种将电路密封引入到核电站多层安全壳的密封区域内的装置。该装置可以在穿过容易受地震或墙体和贯穿件热胀影响而发生彼此相对位移的内墙和外墙的贯穿件中使用。本发明的目的是提高使用难以弯曲的高压电线的密封电缆引入装置的可靠性。为实现所提出的目的,提供一种穿过核电站安全壳外墙和内墙的密封电缆引入装置,其包括一个设置在内墙(1)中的嵌入式套管(3),所述套管内部刚性地固定有电缆(2)的入口部(44)。沿着套管(3)的轴线在外墙(11)安装有补偿电缆(2)与外墙(11)之间相对运动的装置。所述补偿装置具有一个管道(19),在所述管道的外端部(20)上有一个波纹管(24),在外墙(11)内表面(18)的管道的另外一端(21)上对称安装有第二个类似的波纹管(25)。波纹管(24)和(25)的活动端(30)和(31)设置成圆锥形,其内表面(28)和(29)是电缆(2)出口部(46)的支撑件,所述电缆(2)的出口部(46)自由地设置在相对于管道(19)的内表面(49)具有间隙(47)的管道(19)内。电缆(2)外表面的外皮(48)与管道(19)内表面(49)之间的间隙47根据设计计算进行选择。间隙(47)应不小于内墙(1)相对于外墙(11)的一个平面内的最大正交热学‑地震位移幅度以及管道(19)内电缆(2)同轴位置的改变幅度。
