Description

Technical Field

[0001] The utility model relates to a reactor frame and a dry-type air-core reactor, belonging to the technical field of reactors. Background Art

[0002] A dry-type air-core reactor (reactor) is an inductive high-voltage electrical appliance in which the magnetic flux forms a loop through air, and the winding and iron core are not immersed in an insulating liquid, including shunt reactors and series reactors that are usually used in reactive power compensation devices; current-limiting reactors for limiting inrush current or fault current, and high-voltage shunt reactors for compensating capacitive current of high-voltage and extra-high-voltage lines, etc. Existing reactors include star-shaped frames at both ends, post insulators in the middle part, and non-magnetic metal bases at the bottom. The winding uses a copper or aluminum coil and is encapsulated with epoxy resin as the winding.

[0003] Among them, reactors used in some existing fields have certain requirements for volume. For example, in mobile substations, reactors are designed to be small in volume to prevent affecting the operation of other equipment. Therefore, they are usually directly designed to be between 200 mm and 300 mm. However, such a design will cause the winding to be unable to be completed according to the original winding method. Therefore, a reactor frame that is compatible with small volume and conventional winding requirements is needed. Summary of the Utility Model

[0004] Therefore, the purpose of the present utility model is to provide a reactor frame and a dry-type air-core reactor, which can ensure the conventional winding function of the reactor while reducing the volume of the reactor.

[0010] Further, the first bracket is a one-piece aluminum bar; the second bracket is a cross-shaped aluminum bar.

[0011] Further, the positioning unit is a positioning pin;

[0012] Positioning pins are respectively welded to both ends of the one-piece aluminum bar;

[0013] The single-side welding of the cross-shaped aluminum row has positioning pins; the distance between the positioning pins is greater than or equal to the diameter of the insulating cylinder.

[0014] Furthermore, the linear aluminum row and / or the cross-shaped aluminum row are provided with insulator mounting holes between the positioning pins.

[0015] Furthermore, the capacitor frame is connected to the post insulator outside the capacitor frame through the insulator mounting holes.

[0016] Furthermore, the fixed shaft is connected to the winding machine outside the capacitor frame.

[0017] On the other hand, the present invention provides a hollow reactor, including the reactor frame provided in the previous aspect.

[0025] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0026] As Figure 1 、Figure 2 , Figure 3 and Figure 4 As shown in ,

[0027] , the present utility model provides a reactor frame body, including:

[0027] The first bracket 1 is provided with a positioning unit 2 and a first mounting hole 3 at the bottom;

[0028] The second bracket 9 is provided with a positioning unit 2 and a second mounting hole 4 at the top; wherein the first bracket 1 and the second bracket 9 are arranged vertically; both can adopt a single - character or cross structure, but as a preferred implementation mode, since the second bracket 9 is used as the bottom bracket, a more robust structure is required. Considering lightweight, the first bracket 1 adopts a single - character aluminum bar, and the second bracket 9 adopts a cross - shaped aluminum bar. And the single - character aluminum bar is provided with an upper incoming line row at the edge of the long side, and the cross - shaped aluminum bar is provided with a lower outgoing line row at the edge of the long side to realize the winding of the winding.

[0029] The insulating cylinder 5 is fixed to the first bracket 1 through the positioning unit 2 and fixed to the second bracket 9 through the positioning unit 2. The positioning unit 2 includes but is not limited to using positioning nails; the insulating cylinder 5 serves as the framework between the first bracket 1 and the second bracket 9, plays a supporting role for both in the vertical direction, and also needs to wind the winding. Most of the frameworks used at present are structures of a mold core ring, a central shaft, and a support frame, so they are often large in size, and using the insulating cylinder 5 is beneficial to reducing the volume.

[0030] Positioning nails are welded to both ends of the single - character aluminum bar respectively; positioning nails are welded to one - side direction of the cross - shaped aluminum bar; the distance between the positioning nails is equal to or slightly larger than the diameter of the insulating cylinder 5. The role of the positioning nails is to fix and limit the insulating cylinder 5, and at the same time, it can rotate synchronously while the first bracket 1 and the second bracket 9 rotate.

[0031] Insulator mounting holes 7 are provided between the positioning nails on the single - character aluminum bar and / or the cross - shaped aluminum bar. Specifically, the insulator mounting holes 7 provided on the single - character aluminum bar are equidistantly distributed on both sides centered on the first mounting hole 3; and the aluminum bar provided on the cross - shaped aluminum bar is equidistantly distributed in the vertical direction centered on the second mounting hole 4. As Figure 5 shown, the role of the insulator mounting holes 7 is to connect the pillar insulators 8 outside the external capacitor frame body. The pillar insulators 8 complete the installation of the reactor frame body by connecting to a non - magnetic metal base.

[0032] The fixed shaft 6 is fixedly connected to the first bracket 1 through the first mounting hole 3 and fixedly connected to the first bracket 1 through the second mounting hole 4. The function of the fixed shaft 6 is to limit the first bracket 1 and the second bracket 9, and it is connected to the winding machine outside the capacitor frame body. Driven by the winding machine, the first bracket 1 and the second bracket 9 rotate, and the upper wire row, the lower wire row and the insulating cylinder 5 are used for winding to form a winding.

[0033] A reactor frame body provided by the present utility model adopts two brackets arranged in the vertical direction, and an insulating cylinder is used as a skeleton between the brackets. The fixed shaft is used as a support between the two brackets, so that the insulating cylinder replaces the structures of the existing mold core ring, support frame and central shaft and can perform winding operations. Therefore, the goal of reducing the volume of the reactor while ensuring the conventional winding function of the reactor is achieved.

[0034] In addition, the present application also provides a hollow reactor, which adopts the reactor frame body provided in the foregoing embodiment, has the same structure, and achieves the same technical effects, which will not be elaborated here.

[0035] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
