第３図は避雷器取付容器１１の構成を示す断面図である
。FIG. 3 is a sectional view showing the structure of the lightning arrester mounting container 11.
第３図において、取付容器１１の底部２はエポキシ樹脂
等の絶縁物質で形成されこれに避雷器７の取付ホルダー
兼端子１３が取付けられ、接続導体６と結んである。In FIG. 3, the bottom part 2 of the mounting container 11 is made of an insulating material such as epoxy resin, and a mounting holder/terminal 13 of the lightning arrester 7 is attached to this bottom part 2 and connected to the connecting conductor 6.
取付ホルダー兼端子１３には避雷器７の線路側端子係止
用の挿嵌部が設けられている。The mounting holder/terminal 13 is provided with an insertion portion for locking the line side terminal of the lightning arrester 7.
１４は取付容器１１の蓋で接地側端子１５を有し取付容
器１１にボルト締め等の方法により固定される。Reference numeral 14 denotes a lid of the mounting container 11, which has a ground terminal 15 and is fixed to the mounting container 11 by bolting or the like.
避雷器７を接続する場合は取付容器１１内の取付ホルダ
ー兼端子１３の係止用挿嵌部に当該素子を係止した後取
付容器の蓋１４をすることにより着脱自在に装着、接続
することができる。When connecting the lightning arrester 7, the device can be detachably attached and connected by locking the element in the locking insertion part of the mounting holder/terminal 13 in the mounting container 11 and then covering the lid 14 of the mounting container. can.
なお上記実施例では取付容器底部を絶縁物質としたが取
付容器全体を絶縁物としてもよく、特に限定されるもの
ではない。In the above embodiment, the bottom of the mounting container is made of an insulating material, but the entire mounting container may be made of an insulating material, and is not particularly limited.
また取付容器内に絶縁油を入れ絶縁性の向上を図っても
よい。Additionally, insulating oil may be placed in the mounting container to improve insulation.
更に取付容器底部に設けられた端子１３の係止用挿嵌部
