Description

Technical Field

[0001] This application relates to a corner module for a pipeline, specifically a corner module for a pipeline of a gas-insulated switchgear (GIS), and to a gas-insulated switchgear including the corner module. Background Technology

[0002] Gas-insulated switchgear (GIS) pipes contain various conductors. In the prior art, pipes at corners usually require various configurations of corner modules to achieve different turning angles. Therefore, there are many parts required, the structure is complex, the development cycle is long, it is not conducive to standardized design, and the angle of the corner module is fixed and cannot be adjusted. Utility Model Content

[0003] In view of this, the present invention proposes a corner module for pipelines, which can adjust the corner angle of the corner module as needed to adapt to complex installation environments. It has a simple structure and solves the above-mentioned defects in the prior art.

[0004] According to one embodiment of this application, a corner module for a pipe is provided, including two corner components, each corner component having a hollow shell structure to define an extension channel extending along the channel axis inside, each corner component including a mating end face located at a first end of the extension channel, the mating end face being inclined relative to the extension channel, the two corner components being connected to each other through their respective mating end faces, and the included angle between the channel axes of the two corner components being changed by adjusting the relative rotational position of the two mating end faces in the circumferential direction.

[0005] The corner module includes two corner components. By changing the relative rotational position of the two corner components in the circumferential direction between the two mating end faces, the angle between the two extended channels can be easily adjusted, that is, the corner angle can be adjusted to realize the pipe turning, so as to adapt to complex and different installation environments. The corner module has a simple structure, is easy to manufacture, and has a low cost.

[0006] Furthermore, each corner component includes a first flange located at the first end of the extended channel, with mating faces formed on the first flange. The two corner components are connected to each other through their respective first flanges. Each of the two first flanges has a plurality of connecting holes arranged in a circumferential direction. The two corner components are connected by fasteners passing through the connecting holes, and the included angle between the channel axes of the two corner components is changed by selective engagement between the plurality of connecting holes of the two first flanges.

[0007] By providing multiple connection holes on the first flange, a wider range of rotation angles can be adjusted with a simple structure.

[0008] Furthermore, each corner component includes a second flange located at the second end of the extension channel, the second flange being perpendicular to the extension channel. Each corner component also includes a cylindrical pipe and a spherical pipe connected to each other to form an integral structure. The cylindrical pipe defines the channel axis, the end of the spherical pipe away from the cylindrical pipe is connected to the first flange, and the end of the cylindrical pipe away from the spherical pipe is connected to the second flange.

[0009] By setting a second flange, corner components can be easily connected to other equipment for greater adaptability.

[0010] Furthermore, the center of the spherical tube is located on the channel axis. This structure simplifies the construction of the corner components and facilitates their manufacture.

[0011] Furthermore, the first flange is configured such that the mating end face passes through the center of the spherical pipe and forms a 45-degree angle with the channel axis defined by the cylindrical pipe. When the two corner components are fixed together, the positional relationship between the two corner components includes a vertical state, an intermediate state, and a parallel state. In the vertical state, the angle between the two channel axes is 90 degrees; in the parallel state, the angle between the two channel axes is 180 degrees; and in the intermediate state, the angle between the two channel axes is between 90 degrees and 180 degrees.

[0012] The above structure allows the two corner modules to be adjusted to multiple angles to adapt to different application scenarios.

[0013] Furthermore, the connecting hole on one of the two first flanges is an elongated hole extending along the circumference, and the connecting hole on the other flange is a circular hole; or the connecting holes on both first flanges are elongated holes extending along the circumference.

[0014] By setting elongated or circular holes on the first flange, the structure is simple and the connection is stable.

[0015] Furthermore, there are eight connecting holes, which allows for adjustments to more corner angles.

[0016] Furthermore, the fasteners include bolts and nuts, which are simple in structure and easy to disassemble.

[0017] According to another embodiment of this application, a gas-insulated switchgear is provided, including the aforementioned corner module for pipelines. By using the aforementioned corner module for pipelines, the gas-insulated switchgear can achieve pipeline connection, and the angle of the corner module can be adjusted as needed to adapt to complex installation environments.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of this application, a corner module 1 for a pipe is provided. The corner module 1 includes two corner components 2.

[0040] Each corner component 2 has a hollow shell structure to define an extension channel 8 extending along the channel axis F inside. Each corner component 2 includes a mating end face 5 located at a first end of the extension channel 8, the mating end face 5 being inclined relative to the extension channel 8.

[0041] The two corner components 2 are connected to each other through their respective mating end faces 5, and the included angle between the channel axes F of the two corner components 2 is changed by adjusting the relative rotational position of the two mating end faces 5 in the circumferential direction.

[0042] Each corner component 2 includes a first flange 6 located at the first end of the extension channel 8, with a mating end face 5 formed on the first flange 6. Two corner components 2 are connected to each other via their respective first flanges 6. Figures 3 to 6 As shown.

[0043] Each of the two first flanges 6 has multiple connecting holes 7 arranged in a circumferential direction. The two corner components 2 are connected by fasteners that pass through the connecting holes 7, and the included angle between the channel axes F of the two corner components 2 is changed by selectively engaging the multiple connecting holes 7 of the two first flanges 6.

[0044] Each corner component 2 includes a second flange 9 located at the second end of the extension channel 8, the second flange 9 being arranged perpendicularly to the extension channel 8.

[0045] Each corner component 2 also includes a cylindrical pipe 3 and a spherical pipe 4 connected to each other to form an integral structure. The cylindrical pipe 3 defines the channel axis F.
