Background
In the current power system, the voltage level gradually rises, and the insulation distance between some power devices needs to be increased due to the consideration of electrical safety distance, so that the occupied area is increased, and the situation is particularly serious in the occasions with numerous power devices and high voltage levels. In order to relieve the ground pressure, a plurality of air-core reactors are arranged in a mode that a plurality of devices are stacked up and down. However, since the voltage class is increased, the difficulty of insulating the reactor from the ground is increased, which means that a higher post insulator is required to ensure the creepage distance. Due to the fact that the installation mode and the supporting height of the reactors stacked up and down are improved, the anti-seismic performance of the structure is weakened, and the reactors are easily damaged by earthquakes.

example 3
Fig. 3 schematically illustrates at least a part of still another exemplary dry-type air-core reactor working group of the present invention, which is generally formed by combining the above-described dry-type reactor groups of embodiment 1 shown in fig. 1 and embodiment 2 shown in fig. 2, and specifically illustrates three vertically arranged reactors and two horizontally arranged reactors, which are connected and supported by the supporting and shielding device 1 shown in fig. 4, the supporting and shielding device 1' shown in fig. 5, and the post insulator 6.
Although three exemplary embodiments of the present application are described in detail above, it should be understood by those skilled in the art that the technical solutions of the present application are by no means limited to the three embodiments shown above. The number of reactors can be increased by further expanding in the lateral and longitudinal directions on the basis of the above-described three embodiments, for example, the first vertical reactor 5a and the second vertical reactor 5c in embodiment 1 shown in fig. 1 can also be connected with other reactors arranged vertically or laterally by supporting the shielding means thereabove, and the vertical reactors 5d and 5f in embodiment 2 shown in fig. 2 can be connected with other reactors arranged vertically or laterally.
The above description has been made in connection with the accompanying drawings, the detailed description, and the examples to connect a vertically arranged reactor and a horizontally arranged reactor to each other by a support shield device configured with a horizontal plate member and a vertical plate member, and to constitute a reactor working group including both the vertical reactor and the horizontal reactor. Compared with the traditional mode that the air-core reactors are all vertically arranged, the reactor working group formed by arrangement can more fully utilize high space, and the floor area of the reactor working group is saved. In addition, the transversely arranged reactors serve as the cross beam between the two vertically arranged reactors for connection, the mechanical connection stability between the reactors is further enhanced, and the anti-seismic performance of the whole reactor working group is further improved.
a plurality of seat members are provided on the horizontal plate member (i.e., the upper plate member 7, the lower plate members 8, 8 ') and the vertical plate member (i.e., the vertical plate members 9, 9') in the supporting shield device, respectively, and are arranged at intervals along the same circumference having the same radius as the radius of the circumference at which the connection terminals on the respective arms of the reactor end hanger are located. That is, the reactor can be connected with the horizontal plate member or the vertical plate member supporting the shielding device in various orientations, thereby making it possible to flexibly arrange the direction of the entire reactor active group as needed. Therefore, the adaptability to the installation site conditions of the reactor working group can be improved, and the structural stability of the whole reactor working group can be improved.
Although the method of arranging two reactors arranged vertically in a horizontal direction in two reactor arrangements has been described in the embodiments and examples with reference to the drawings, it will be understood by those skilled in the art that other forms of supporting and shielding device may be used to arrange two reactors arranged vertically in a horizontal direction between two dry air reactors arranged vertically to form a dry air reactor working group of the present application without departing from the spirit of the present invention.
The above description of the embodiments and examples of the present invention is intended to enable those skilled in the art to make or practice the invention, but the scope of the invention is not limited to the above embodiments and examples. Various changes and modifications to the above embodiments may be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications also fall within the scope of the invention.
For example, due to different practical engineering requirements, a certain number of multiple stacks of reactors arranged vertically in each group may occur, and a certain number of multiple series connections of reactors arranged horizontally may also occur, not limited to the case where there is only one reactor arranged vertically or horizontally in each segment in the embodiment. In addition, since the supporting shield device can rotate in a horizontal plane, the actual reactor arrangement direction is not limited to the same vertical plane.
thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
