この考案は、並設された機器間の相間絶縁を保
持するため、機器間に配設される相間絶縁用の相
間バリヤに関する。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an interphase barrier for interphase insulation disposed between devices in order to maintain interphase insulation between devices installed in parallel.
従来、３相機器の相間絶縁は、第４図に示すよ
うになつている。
Conventionally, interphase insulation of three-phase equipment is as shown in FIG. 4.
同図において、１は底板、２はフレーム、３は
底板１上に並設された３相の機器、４は機器３の
遮断部分であり、外部端子に接続されている。５
は遮断部分４を開閉する操作軸、６は機器３間に
配設された１枚の板状の相間バリヤである。 In the figure, 1 is a bottom plate, 2 is a frame, 3 is a three-phase device arranged in parallel on the bottom plate 1, and 4 is a cutoff part of the device 3, which is connected to an external terminal. 5
is an operating shaft for opening and closing the blocking portion 4, and 6 is a plate-shaped interphase barrier disposed between the devices 3.
そして、機器３間の相間絶縁は、気中のみでは
気中寸法が大きくなるため、相間バリヤ６を設置
し、気中寸法を小さくしている。 Since the phase-to-phase insulation between the devices 3 requires only air, the size in the air becomes large, so an inter-phase barrier 6 is installed to reduce the size in the air.
しかし、相間バリヤ６が汚損すると、部分放電
を起し、バリヤ６が炭化して貫通破壊に至り、地
絡故障として検出される前に相間短絡故障を発生
し、大事故に至る。
However, when the interphase barrier 6 becomes contaminated, partial discharge occurs, and the barrier 6 becomes carbonized, leading to through-breakage, and an interphase short circuit failure occurs before it is detected as a ground fault, resulting in a major accident.
この考案は、前記の点に留意してなされたもの
であり、並設された機器間に配設される相間絶縁
用の相間バリヤにおいて、２つの絶縁層の間に接
地層を介在した相間バリヤである。
This idea was made with the above points in mind, and is an interphase barrier for interphase insulation installed between devices installed in parallel, in which a ground layer is interposed between two insulating layers. It is.
したがつて、この考案によると、絶縁層が汚損
した場合、中間の接地層により地絡故障として検
出されるため、相間短絡故障への移行が防止さ
れ、大事故が発生しない。
Therefore, according to this invention, when the insulating layer is contaminated, it is detected as a ground fault by the intermediate ground layer, so transition to a phase-to-phase short circuit fault is prevented, and a major accident does not occur.
つぎにこの考案を、その実施例を示した第１図
ないし第３図とともに、詳細に説明する。
Next, this invention will be explained in detail with reference to FIGS. 1 to 3 showing examples thereof.
まず、１実施例を示した第１図において、７は
金属板からなる接地層、８は接地層７の両側の周
縁部に設けられたスペーサ、９はスペーサ８を介
して接地層７の両側に重合された絶縁板からなる
絶縁層、１０は接地層７と絶縁層９との間に形成
された気中ギヤツプである。 First, in FIG. 1 showing one embodiment, 7 is a ground layer made of a metal plate, 8 is a spacer provided on the periphery on both sides of the ground layer 7, and 9 is provided on both sides of the ground layer 7 via the spacer 8. The insulating layer 10 is an air gap formed between the ground layer 7 and the insulating layer 9.
したがつて、いずれか一方の絶縁層９が汚損
し、部分放電によつて貫通破壊しても、接地層７
により地絡故障として検出され、相間短絡故障に
移行しない。 Therefore, even if one of the insulating layers 9 is contaminated and breaks through due to partial discharge, the ground layer 7
, it is detected as a ground fault and does not progress to a phase-to-phase short circuit fault.
また、両側の絶縁層９が同時に汚損しても、汚
損度合の差異や両側の絶縁層９の差異などによ
り、微視的に全く同一の炭化があり得ないため、
いずれか一方の汚損の激しい側の絶縁層９が他方
の絶縁層９より先に貫通して破壊する。したがつ
て、相間短絡故障に移行することがない。 Furthermore, even if the insulating layers 9 on both sides are contaminated at the same time, microscopically the same carbonization cannot occur due to the difference in the degree of contamination and the difference in the insulating layers 9 on both sides.
The insulating layer 9 on one of the more heavily contaminated sides penetrates and breaks down before the other insulating layer 9. Therefore, there is no possibility of transition to phase-to-phase short circuit failure.
つぎに、他の実施例を示した第２図は、接地層
７の両面に絶縁層９を一体にモールド成型したも
のである。 Next, FIG. 2 showing another embodiment is one in which an insulating layer 9 is integrally molded on both surfaces of a ground layer 7.
つぎに、さらに他の実施例を示した第３図は、
２枚の絶縁板からなる絶縁層９の片面にそれぞれ
蒸着により金属層１１を形成し、絶縁層７の両面
にそれぞれ金属層１１を接合して絶縁層９を重合
したものである。 Next, FIG. 3 showing still another embodiment,
A metal layer 11 is formed by vapor deposition on one side of an insulating layer 9 consisting of two insulating plates, and the metal layer 11 is bonded to both sides of the insulating layer 7, and the insulating layer 9 is polymerized.
そして、第２図および第３図の場合も、第１図
と同様の作用効果を有する。 The cases of FIGS. 2 and 3 also have the same effects as those of FIG. 1.
以上のように、この考案の相間バリヤによる
と、外側の絶縁層が汚損しても、中間の接地層に
より地絡故障として検出することができ、相間短
絡故障の発生を完全に防止することができる。
As described above, according to the interphase barrier of this invention, even if the outer insulating layer is contaminated, it can be detected as a ground fault by the intermediate ground layer, and the occurrence of interphase short circuit faults can be completely prevented. can.
