【考案の詳細な説明】 〔産業上の利用分野〕 本考案はブロックフィルタに関し、特に電力線搬送通信
装置に使用されるブロックフィルタに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a block filter, and more particularly to a block filter used in a power line carrier communication device.
従来電力線搬送通信装置，特に各家庭におけるホームオ
ートメーション装置においては，隣家との通信の干渉を
防止するために屋内の分電盤等にブロックフィルタを設
置していた。しかし最近でき搬送信号を広帯域（10KHz
〜450KHz）に拡散するスペクトラム拡散通信や電力線FM
インターホン（230KHz〜450KHzの範囲で６波割り当て）
との共用のため，ブロックフィルタ自体の減衰特性も従
来の125KHzや165KHzのみの狭帯域から広帯域化（例えば
100KHz〜450KHz）が求められている。このため，現状の
狭帯域フィルタ（帯域消去型）を互いに帯域をずらして
複数個使用するか，低域通過型のフィルタ構成をとらな
ければならない。而も重畳する商業電力が大きくなって
もその特性を維持しなければならない。Conventionally, in a power line carrier communication device, particularly in a home automation device in each home, a block filter is installed on an indoor distribution board or the like in order to prevent communication interference with a neighboring house. However, recently, the carrier signal has been made wide band (10KHz
~ 450KHz) spread spectrum communication and power line FM
Intercom (6 waves assigned in the range of 230KHz to 450KHz)
Since it is also used as a block filter, the attenuation characteristic of the block filter itself is widened from the conventional narrow band of only 125 KHz or 165 KHz (for example,
100KHz ~ 450KHz) is required. Therefore, it is necessary to use a plurality of current narrow band filters (band elimination type) with their bands shifted from each other, or to take a low pass type filter configuration. Moreover, even if the commercial electric power to be superposed becomes large, its characteristics must be maintained.
しかしながらこのようなフィルタ構成をとるには，これ
までフィルタのコア材に用いられてきたフェライトコア
や圧粉磁芯では，フィルタ形状が大型化し高価になると
いう欠点があった。However, in the case of adopting such a filter structure, the ferrite core and the dust core that have been used as the core material of the filter have a drawback that the filter shape becomes large and expensive.
したがって本考案の目的は広帯域で、重畳する商業電力
が大きくなっても使用出来、しかも小型計量で安価な電

ロックフィルタが得られる。According to the present invention, a home-side inductor used for a power line carrier communication device, one end of which is connected to a home-side live line, and one end of which is connected to a home-side live line and the other end of which is connected to the other end of the home-side inductor. In a block filter including an outside inductor to be connected, only the inside inductor is a magnetic core made of an amorphous magnetic alloy in which microcrystalline powder is dispersed in an amorphous phase, whereby the inside inductor is formed. In addition, a block filter for a power line carrier communication device is obtained, which has a characteristic that magnetic saturation does not occur even when a commercial power supply current flows up to a maximum value.

ることができる。With the above-described structure, the amorphous phase provides a wide band with a high magnetic permeability and a low coercive force, and the uniform dispersion of fine crystal grains can prevent magnetic saturation even when a large current of a commercial power supply is applied.
以下図面に基づいて本考案の実施例を詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

コアーを用いた乗越えインダクタである。FIG. 1 shows the structure of a block filter according to the present invention. Two inductors 1 using amorphous magnetic cores containing fine crystals are used for both live wires 11 on the inside of the home of the single-phase three-wire type power line block filter, and pure iron dust cores are used for both live wires 13 on the outside of the home. It is a two-stage low-pass filter that uses the two inductors 2 used and inserts four film capacitors 4 between the live line and the neutral lines 12 and 14. 5 is a capacitor for signal bypass between different phases, and 3 and 6 are crossover inductors using a ferrite ring core.

実効透磁率μｅを約300としたのは，これまで圧粉磁芯
（モリパーμｅ≒120）やセンダスト（μｅ≒80）等）
では実現がむずかしいこと，電流重畳によるμｅの低下
が小さいこと（約400e以内において）等のためである。The magnetic core of the inductor 1 is made by winding a ribbon of Fe-based amorphous alloy (effective magnetic permeability μe is about 2000 to 4000) with a plate thickness of 0.025 mm in an annular shape and then dispersing the fine crystal grains by heat treatment to make the inductor effective. The magnetic permeability μe is adjusted to about 300.
The effective magnetic permeability μe was set to about 300 because the powder magnetic core (Molyper μe ≈120), sendust (μe ≈80), etc.)
Is difficult to realize, and the decrease of μe due to current superposition is small (within about 400e).
以上のような構成により従来のモリパーダストを使用し
たときにくらべコア断面積で約1/2に，フィルタ全体で
は体積比で約10％小形化できた。With the above structure, the core cross-sectional area was reduced to about half that of conventional molyper dust, and the volume of the entire filter was reduced by about 10%.
