Description
【発明の詳細な説明】
電力線搬送用ブロッキング・コイルを絶縁耐力および熱
電導率の大きい媒体たとえば、油や六弗化硫黄ガス（Ｓ
Ｆ６）を充顛した絶縁材製容器内に収納し、４・形化を

主コイルとともに同調装置が容器中に収納されることに
なる。[Detailed description of the invention] Blocking coils for power line conveyance are used in media with high dielectric strength and thermal conductivity, such as oil and sulfur hexafluoride gas (S).
F6) is stored in an insulating material container filled with 4. If you try to measure the shape of the blocking coil, the conventional blocking coil has a tuning device connected in parallel with the main coil.
A tuning device will be housed in the container along with the main coil.

都合がある。この発明のブロッキング・コイルは上記不
都合を解消したもので、第１図に回路図において、商用
周波電流を流す主コイル（１次コイル）１と磁気的に結

で電気共振させ、１次側から見たインピーダンスを高く
することにより、高周波阻止効果を得るものである。For this reason, when changing the blocking frequency band or replacing the tuning device in the event of a failure of the tuning device, there is an inconvenience that operations such as removing and refilling the cooling/insulating medium must be performed at the same time. The blocking coil of this invention eliminates the above-mentioned disadvantages, and as shown in the circuit diagram in Figure 1, the blocking coil is tuned to a secondary coil 2 which is magnetically coupled to a main coil (primary coil) 1 through which commercial frequency current flows. A high frequency blocking effect is obtained by connecting the device 3 and causing electrical resonance at a high frequency to increase the impedance seen from the primary side.
また、１次コイル１を収納した容器は絶縁材製であるが
、その理由は、金属製容器を使用すると、ブロッキング
・コイルの磁束により、容器に渦電流損を生じ、温度が
異常上昇することと、ィンダクタンスを減少することを
防ぐためである。In addition, the container that houses the primary coil 1 is made of insulating material, but the reason for this is that if a metal container is used, the magnetic flux of the blocking coil will cause eddy current loss in the container, causing an abnormal temperature rise. This is to prevent the inductance from decreasing.

ング、９は避電器、１０は冷却器である。FIG. 2 is a diagram showing an embodiment of the blocking coil of the present invention, in which the main coil 1 is housed in a container 4 made of an insulating material, and the secondary coil 2 is wound around the outside of the container 4. 1
A tuning device 3 is connected to the secondary coil 2. The container 4 is supported by a station post insulator 5 and a pedestal 6. 7 is a power line, 8 is a bushing, 9 is an earth arrester, and 10 is a cooler.

に磁気結合される。In the blocking coil of this invention, the tuning device is not connected in parallel with the main coil, but the main coil is housed in a container made of insulating material, and the secondary coil is wound outside, so that eddy currents are not generated in the container. It does not generate heat and is effectively magnetically coupled to the secondary coil.
そして２次コイルへ同調装置を接続したから、ブロッキ

障の際に、同調装置を容易に取替えることができるもの
である。Since the tuning device is connected to the secondary coil, the tuning device can be easily replaced when the blocking coil's blocking frequency band is changed or when the tuning device breaks down.
