Embodiment 1
[0028] Such as figure 1 and figure 2 As shown, the self-cooling conductor of this embodiment includes a conductor body 1 made of conductive material. The conductor body 1 is provided with a plurality of closed inner cavities 11, and each closed inner cavity 11 is filled with a phase change refrigerant. The volume in liquid or solid state is smaller than the volume of the closed inner cavity 11 . The self-cooling conductor can be used as a winding of a reactor or a transformer. When the reactor or transformer is working, the conductor body 1 and the iron core 2 of the reactor or transformer generate heat, and the phase-change refrigerant in the closed cavity 11 of the conductor body 1 It will absorb heat and produce a phase change from liquid or solid to vapor state. After the phase change refrigerant becomes vapor, it will rise to the upper part of the closed inner cavity 11. The phase change refrigerant will change due to the change of state (solid form or liquid form into ...
Embodiment 2
[0035] The self-cooling conductor of this embodiment is basically the same as that of Embodiment 1, the main difference is that, as image 3 and Figure 4As shown, in this embodiment, the cross section of the closed cavity 11 perpendicular to the width direction is rectangular. Of course, in other embodiments, the section perpendicular to the width direction of the enclosed cavity 11 may also be a polygon other than a rectangle, or a combination of various shapes.
Embodiment 3
[0037] Such as Figure 5 and Figure 6 As shown, a reactor or transformer includes an iron core 2 and a winding wound on the iron core 2. The winding is made of the self-cooling conductor in Embodiment 1, and the conductor body 1 of the self-cooling conductor It is in the shape of a strip, and the width direction of the conductor body 1 is consistent with the vertical direction, that is, each strip-shaped closed cavity 11 in the self-cooling conductor is arranged along the vertical direction, which is beneficial for the phase-change refrigerant to rise to the closed cavity in the vapor state 11 top.
[0038] The reactor or transformer in this embodiment can be an ordinary single-phase transformer or reactor, a three-phase transformer or reactor, a multi-phase transformer or reactor, a hollow single-phase transformer or reactor, a hollow three-phase transformer or reactor, a hollow Multiphase transformers or reactors.
[0039] When the reactor or transformer is working, its ...
