にすることにある。[Detailed description of the invention] The present invention relates to a block filter device for power line transport control.The purpose of the invention is to reduce the size of the block filter, and to provide power line transport control between sub-main circuits. It is an object of the present invention to realize a block filter device for power line transport control that can perform control with a simple and inexpensive circuit configuration.

８が電流容量により大型になり、コスト高になる
という欠点を有していた。 The conventional block filter device for power line transfer control has a large capacity block filter 4' connected to the load side of the main breaker 6, as shown in FIG.
This prevents the carrier signal from leaking to the power supply side when the power line carrier is controlled. In this case, the block filter 4' consists of a parallel resonant circuit 8 connected in series to each line and resonating at the carrier wave number, as shown in FIG. 1b.
, series resonant circuits 9, 9 connected between the lines and the neutral line and resonating with the carrier frequency, and an interphase crossover circuit 10 connected between the lines and resonating with the carrier frequency. This device has the disadvantage that the parallel resonant circuit 8 becomes large due to its current capacity, resulting in high cost.
本考案はかかる点に鑑みてなされたもので、以
下実施例により詳細に説明する。 The present invention has been devised in view of this point, and will be described in detail below with reference to Examples.

要となる。 In Figure 2a, 1 is a large-capacity main circuit,
The main circuit breaker 6 is connected, and this main circuit 1
is separated into a plurality of sub-main circuits 2, 2, and a small-capacity block filter 4 is connected to the load side of a sub-main breaker 3 connected to the sub-main circuits 2, 2, respectively. The block filter 4 has the same structure as the conventional block filter 4' described above, or has the interphase crossover circuit 10.
Let's assume that it's gone. 5 is a resonant circuit that resonates with the carrier frequency, as shown in Figure 2b.
An LC series resonant circuit is connected between each in-phase circuit on the load side of the block filter 4. At this time, if the interphase crossover circuit 10 is connected within the block filter 4, either the resonant circuit 5 1 or the resonant circuit 5 3 and either the resonant circuit 5 1 ′ or the resonant circuit 5 3 ′ are unnecessary.

幹回路２，２間でも電力線搬送制御ができる。 In this way, the block filter 4 only needs to have a small capacity, so it can be made small and inexpensive, and since the resonant circuit 5 is connected between each in-phase of the sub-main circuits 2, 2, the power line can be connected even between the sub-main circuits 2, 2. Conveyance control is possible.

えるという効果がある。 As mentioned above, the present invention separates a large-capacity main circuit into a plurality of sub-main circuits, connects a block filter to each of the load sides of the sub-main breaker, and connects each in-phase circuit between the load sides of the block filters. It connects a resonant circuit consisting of an LC series resonant circuit that resonates with the frequency, and the large-capacity main circuit is separated into multiple sub-main circuits, each with a block filter connected to the load side of the sub-main breaker. ,
The effect is that the block filter can be made small and inexpensive, and by connecting an LC series resonant circuit between each common phase on the load side of the block filter, multiple circuits can be connected simply by adding a simple circuit. The sub-main circuit can be considered as the same signal system,
Since power line transfer control (bidirectional signal transmission) between the sub-main circuits to which the resonant circuit is connected is possible, the block filter can be downsized with a simple circuit configuration without any loss of power line transfer control function. This has the effect of easily realizing miniaturization and cost reduction of the entire device. Furthermore, the cross-over circuit is formed by a resonant circuit made up of passive elements, and does not require a special circuit power source.Moreover, by simply connecting the resonant circuit between the sub-main circuits related to control, It is possible to form a control signal system according to the situation at the site, and has the advantage that construction can be easily performed.
