Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “connected to” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity o...

Abstract

The invention belongs to the technical field of nuclear power station power transmission and distribution and protection, and provides a thermal expansion and cold contraction deformation displacementcompensation structure for a GIL pipe of a nuclear power station. The structure comprises a telescopic pipe which is used for connecting the joint of two GIL pipes which are arranged on the verticalplane and are horizontally and vertically arranged, and also comprises a movable connecting piece used for supporting the telescopic pipe. According to the thermal expansion and cold contraction deformation displacement compensation structure provided by the invention, the telescopic pipe and the movable connecting piece are disposed at the joint of two GIL pipes arranged on the vertical plane andarranged horizontally and vertically; a supporting plate and a hinged support of the movable connecting piece are connected to the two ends of the telescopic pipe correspondingly; the support plate rotationally connected through the pivot is matched with the hinged support; therefore, the telescopic pipe can be bent around a pivot to compensate the bending direction and the bending stress of theGIL pipes, so that the displacement generated by thermal expansion and cold contraction deformation of the GIL pipes can be compensated and absorbed, and the GIL pipes are prevented from being damagedby the deformation caused by thermal expansion and cold contraction.

Description

technical field [0001] The invention belongs to the technical field of power transmission, distribution and protection of nuclear power plants, and more specifically relates to a displacement compensation structure for thermal expansion and cold contraction deformation of a GIL pipeline in a nuclear power plant. Background technique [0002] Gas-insulated transmission line (corresponding to English Gas-insulated Iransmission Line abbreviated as GIL) is a kind of insulating gas (SF 6 gas or SF 6 and N 2 Mixed gas) insulation, high voltage, high current power transmission equipment with coaxial arrangement of shell and conductor. Compared with traditional overhead lines, gas insulated transmission lines have the advantages of low loss, good safety protection, small footprint, large power distribution capacity, and long transmission distance. Distant cities provide a compact, reliable, and economical means of delivering electricity. Due to the long route of the GIL pipeline...
