Description
Technical Field
The invention belongs to the technical field of transformer equipment manufacturing, and particularly relates to a non-confluence reactor hanging bracket device and a reactor.
Background
With the rapid development of reactor manufacturing technology, the reactor capacity is increasing. Because the traditional reactor hanging bracket hub adopts an aluminum annular hub, under the action of alternating magnetic fields generated by the reactor windings, the reactor hanging bracket positioned above and below the reactor windings is easy to form circulation, thereby causing the overheating problem of metal pieces at the reactor hanging bracket. Particularly, under the condition of stacking two reactor coils, the metal piece at the hanger frame is overheated to cause insulation damage at the metal transition seat between the two coils, and further the circulation of the hanger frame-metal transition seat-hanger frame is caused to generate, so that structures such as a connecting bolt, a support plate and the like are overheated rapidly.
In the prior art, there are many methods for preventing the metal connecting piece from heating, for example, a chinese patent document with the application date of 2015, 8 and 19, the application number of 201520624533.7 and the name of "combined suspension arm for current limiting reactor", where the combined suspension arm in the patent document includes a dry reactor and a plurality of combined suspension arms, the plurality of combined suspension arms are uniformly distributed along the circumference and welded with a central hub to form a reactor suspension frame, and the reactor suspension frame has a star-shaped structure; the combined suspension arms comprise aluminum alloy plates and stainless steel plates, and two adjacent combined suspension arms are fixed through tie bars and a plurality of horizontal binding belts to prevent the suspension arms from deforming. The aluminum alloy plate and the stainless steel plate are connected together through a plurality of rivets, and the reason for adopting stainless steel and aluminum alloy materials is as follows: the strength of the stainless steel is higher than that of the aluminum alloy material, and the resistivity is far higher than that of the aluminum alloy material; conduction through the aluminum alloy plate; the stainless steel plate increases the structural strength, reduces the volume of the aluminum alloy suspension arm, reduces the loss of the suspension arm and prevents the metal structural member from heating. The reactor hanger of the combined boom of this patent document is still very prone to circulating currents, resulting in overheating problems of the metal piece at the reactor hanger.
From the above analysis, it can be seen that the reactor hanger of the prior art has the following characteristics and drawbacks:
1. circulation is easily formed, resulting in overheating problems of the metal piece at the reactor hanger. The overheat of the metal part at the hanger causes insulation damage at the metal transition seat between the two coils, further causes circulation of the hanger-metal transition seat-hanger to generate, and causes rapid overheat of structures such as a connecting bolt, a support plate and the like.
2. The stability is poor. When the metal piece at the hanger is overheated, the whole reactor can not normally run, and the stability of the reactor is affected.

In summary, the non-converging reactor hanging bracket device 1 provided by the invention selects the material of the hub part as non-magnetic steel, namely, the hub part is the non-magnetic steel hub part 11, and simultaneously, the middle ring part 111 of the non-magnetic steel hub part 11 is designed to be an open middle ring part, so that the circulation on the reactor hanging bracket device 1 can be effectively avoided, and the non-converging reactor hanging bracket device 1 provided by the invention can not generate heat.
To facilitate the mounting between the boom 13 and the extension 112, the invention further comprises a plurality of connection plates for connecting the boom 13 and the extension 112, such that the boom 13 is fixed to the extension 112 by the connection plates. In practice, as shown in fig. 2 and 3, one side of one connection plate is connected to the extension 112 by a stainless steel bolt, and the other side of the connection plate is connected to the boom 13 by a stainless steel bolt.

In fig. 3, there are 8 connection plates, which are divided into a non-magnetic steel connection plate 14 and 7 epoxy connection plates 12, the non-magnetic steel connection plate 14 being located on the same side of the extension 112 and the boom 13 to which it is connected. It is possible for those skilled in the art to replace the epoxy connection plates with connection plates of other materials having mechanical and dielectric strength satisfying the requirements.
