Abstract
Description
【発明の詳細な説明】 この発明は、電磁誘導機器に関するものであり。[Detailed description of the invention] The present invention relates to electromagnetic induction equipment.
も企少し詳しくいうならば、高透磁率材料でなる磁気シ

トルなどの電磁誘導機器に関するものである。More specifically, the present invention relates to electromagnetic induction equipment such as a transformer or a reactor housed in a housing provided with a magnetic shield made of a material with high magnetic permeability.
従来、変圧器、リアクトルなどの電磁誘導機器において

束をしやへいする手段が採られていた。これを第１図。Conventionally, when the capacity of electromagnetic induction equipment such as transformers and reactors increases, leakage magnetic flux that enters storage bodies such as tanks and panels that house iron cores and coils increases, resulting in large energy losses. Furthermore, a situation such as the storage body heating up may occur. In order to prevent this, a magnetic shield made of a material with high magnetic permeability is provided in the storage body to suppress leakage magnetic flux. This is shown in Figure 1.
第２図で単相の変圧器を例にとって説明する。The explanation will be given using a single-phase transformer as an example in FIG.

納されている。In the figure, the iron core l and the coil 3 are supported by the end frame cores a and 2b provided at the upper and lower parts of the single-phase three-legged iron core l through which the main magnetic flux passes, and the coil 3 is supported by the clamp element v,
3 is firmly clamped. A transformer T consisting of an iron core 1 and a coil 3 is housed in a tank 6 having a side wall 6a.

に適宜に設け。Now, when a load current flows through this transformer T, a leakage magnetic flux is generated, and a part of it penetrates the side wall 6a of the tank base, causing a large amount of loss, which in turn causes the tank 6 to heat up. Therefore, for large-capacity transformers with large leakage magnetic flux, a magnetic shield made of high magnetic permeability material is appropriately installed in the storage area.

る。Another object of the present invention is to obtain an electromagnetic induction device that generates voltage by electromagnetic induction by crossing a conductor with leakage magnetic flux converged in a magnetic shield.゛Hereinafter, one embodiment of the present invention shown in FIGS. 3 and 3 will be described. In this case, the transformer T is housed in an enclosure AK equipped with a magnetic shield 7. This is similar to the conventional method described above, but in this embodiment, a coil t is wound around a magnetic shield 7, and both ends of the coil g are connected to a side wall 6.
Connect to the output terminal D provided in a. A cooling/heating fan motor 10 is connected to the outside of the output terminal.
つぎに、動作について説明すると、収束された漏れ磁束

として利用するものである。Next, to explain the operation, when the converged leakage magnetic flux passes through the magnetic shield 7, the coil t is caused by electromagnetic induction.
C voltage is generated. This voltage is used as a power source for the fan motor lθ.

負荷条件の場合には、４ね磁束も増加し電圧が上昇して
いる。The voltage taken out from the coil t varies depending on the number of turns of the coil t, so it should be adjusted according to the characteristics of the fan motor IO.
This number of turns can be arbitrarily selected. However, although the fan motor IO is taken as an example here, it can also be used as a supplementary power source for oil pumps and other transformers. Further, there is a leakage magnetic flux amount as a voltage induced in the coil j, and this fl increases as the load current increases. Therefore, it is unthinkable to use a relay that starts the supplementary operation after the voltage becomes suitable for the supplementary operation. Furthermore, in the case of load conditions that require supplementary operation, the magnetic flux increases and the voltage rises.
なお１以上の実施例では単相変圧器について説明したが
、三相変圧器でも同様の効果を得ることができ、その場
合は三相電源として利用することもできる。Note that although a single-phase transformer has been described in one or more embodiments, a three-phase transformer can also achieve the same effect, and in that case, it can also be used as a three-phase power source.
