Problems solved by technology

[0004] (1) Under earthquake action, the cantilever GIS casing has relatively strong vertical vibration, which leads to excessive stress on the suspender and is prone to damage;
[0005] (2) The cantilever GIS casing is only suspended by the vertical boom, and the horizontal lateral force under the earthquake is relatively large. If there is no lateral support, the vertical boom will generate a large bending stress;
However, this utility model is not applicable to the connection of electrical equipment on indoor floors

Embodiment 1

[0029] Such as Figure 1-Figure 5 Shown is a schematic structural diagram of a damping connection device for indoor substation suspending GIS bushing provided in this embodiment, the connection device includes a GIS cantilever bushing 6, and the GIS cantilever bushing 6 passes through a support screw 10 Uniformly fixed on a plurality of horizontal support channel steel 5, both ends of each horizontal support channel steel 5 are fixedly connected with the pre-embedded I-beam 2 through the vertical suspender 7, and the pre-embedded I-beam 2 is fixedly arranged In the roof slab 1 of the production complex building, the two ends of each transverse support channel steel 5 are respectively connected to one end of the oblique steel pipe 3, and the other end of the oblique steel pipe 3 connected to the transverse support channel steel 5 is connected to the pre-embedded The I-beam 2 is fixedly connected. The connection between the oblique steel pipe 3 and the transverse support channe...

Embodiment 2

[0035] Such as Figure 6 Shown is a schematic structural diagram of the damping connection device used in the indoor substation to suspend the GIS casing provided in this embodiment. The difference from Embodiment 1 is that two damping losses are respectively set on the inclined steel pipe 3 provided in this embodiment. The energy device 8, the upper metal plate 14 and the lower metal plate 15 have the same structure and are all elliptical, and the others are the same as in the first embodiment. Installing two damping and energy-dissipating devices 8 on each inclined steel pipe 3 doubles the energy-dissipating and shock-absorbing effect on the cantilever GIS casing.

Abstract

The invention belongs to the field of safety substation equipment technologies and particularly relates to a damping connection device applied to an indoor substation suspended GIS sleeve. The devicecomprises GIS cantilever sleeves, wherein the GIS cantilever sleeves are uniformly and fixedly arranged on multiple transverse supporting steel channels through supporting screws, the two ends of eachtransverse supporting steel channel are fixedly connected with pre-buried I-shaped steel through vertical suspenders, the pre-buried I-shaped steel is fixedly arranged in a production integrated building roof floor, the two ends of each transverse supporting steel channel are connected with one end of a diagonal steel tube, the other end of each diagonal steel tube connected with the corresponding transverse supporting steel channels is fixedly connected with the pre-buried I-shaped steel, and at least one damping energy consumption device is arranged on each diagonal steel tube. Through connection of the damping diagonal connection device and the suspended GIS sleeve, bad influences of multi-point earthquake input on the GIS cantilever sleeves and the suspenders can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of safety transformation equipment, and in particular relates to a damping connection device for suspending GIS bushings in indoor substations. Background technique [0002] Indoor substations have the advantages of saving land and coordinating the building appearance with the surrounding environment. In recent years, they have been more and more widely used in urban construction and development. Indoor substations usually arrange a large number of GIS electrical equipment on the second floor of the generating complex. The GIS inlet bushing is usually suspended by a boom and connected to the second floor electrical equipment and the main transformer riser. Floor electrical equipment usually includes Gas Insulated metal-enclosed Switchgear (GIS), which is filled with SF6 gas at a certain pressure as insulation protection between phases and ground. Under the action of earthquake, the structure of the producti...
