さらに、高圧カットアウト支持部13は、電柱Yに対応して湾曲状(円弧状)に形成され且つ電柱と当接する電柱当接部135を備える。この電柱当接部135は、例えば、腕金Zに高圧カットアウトを取り付ける作業を行う際に、高圧カットアウト支持部13に対して外力が加えられたとしても、外力を分散させて電柱Yにも受け止めさせることができる。   Further, the high-voltage cutout support portion 13 includes a utility pole abutting portion 135 that is formed in a curved shape (arc shape) corresponding to the utility pole Y and abuts on the utility pole. For example, when an external force is applied to the high-voltage cutout support portion 13 when performing an operation of attaching the high-pressure cutout to the arm metal Z, the electric pole contact portion 135 disperses the external force to the electric pole Y. Can also be received.

第2装柱具2は、図9及び図10に示すように、電柱Yから水平方向に突出し、端部で変圧器Xを保持する変圧器保持部(単に「保持部」ともいう)21と、変圧器保持部21を電柱Yに固定させる電柱固定部(単に「固定部」ともいう)22とを備える。   As shown in FIGS. 9 and 10, the second pole post 2 protrudes from the utility pole Y in the horizontal direction, and has a transformer holding portion (also simply referred to as “holding portion”) 21 that holds the transformer X at the end. And a utility pole fixing part (also simply referred to as “fixing part”) 22 for fixing the transformer holding part 21 to the utility pole Y.

In addition, the holding part main body 211 is provided with a hooking part 211a at the base end part for hooking the band member 221 for the electric pole fixing part 22 to fasten the electric pole Y.

変圧器当接部212は、一対の絶縁部材212a,212bを備える。この絶縁部材のうち一方の絶縁部材(以下、「第1絶縁部材」という)212aは、保持部本体211の先端部に設けられる孔211bから突出する突出部212cを備える一方、他方の絶縁部材(以下、「第2絶縁部材」という)212bは、保持部本体211から突出する突出部212cを外嵌するように構成される。   The transformer contact portion 212 includes a pair of insulating members 212a and 212b. One of the insulating members (hereinafter referred to as “first insulating member”) 212 a includes a protruding portion 212 c that protrudes from a hole 211 b provided at the distal end portion of the holding portion main body 211, while the other insulating member ( (Hereinafter referred to as “second insulating member”) 212 b is configured to externally fit a protruding portion 212 c protruding from the holding portion main body 211.

また、変圧器当接部212は、変圧器固定手段213により、変圧器Xの第2被係止部X2に固定される。この変圧器固定手段213は、第2被係止部X2の溝及び一対の絶縁部材212a,212bの中央部にそれぞれ設けられる孔を挿通するボルト213aと、このボルト213aに螺合されるナット212bとを備える。   Further, the transformer abutment portion 212 is fixed to the second locked portion X2 of the transformer X by the transformer fixing means 213. The transformer fixing means 213 includes a bolt 213a inserted through a groove of the second locked portion X2 and a central portion of the pair of insulating members 212a and 212b, and a nut 212b screwed to the bolt 213a. With.

したがって、変圧器Xの第2被係止部X2と、保持部本体211とは、一対の絶縁部材212a,212bにより絶縁されている。即ち、変圧器Xと電柱Yとは、変圧器当接部212により絶縁されている。   Therefore, the second locked portion X2 of the transformer X and the holding portion main body 211 are insulated by the pair of insulating members 212a and 212b. That is, the transformer X and the utility pole Y are insulated by the transformer contact portion 212.

以上より、本実施形態に係る変圧器装柱具は、固定部11が電柱Yから水平方向に突出する保持部12を電柱Yに固定し、保持部12が端部で変圧器Xを保持するため、変圧器Xが電柱Yに装着される。そして、保持部12が絶縁性を有するアーム部121を備えるため、変圧器Xと電柱Yとを絶縁することができる。   As described above, in the transformer pole device according to the present embodiment, the fixing portion 11 fixes the holding portion 12 protruding in the horizontal direction from the utility pole Y to the utility pole Y, and the holding portion 12 holds the transformer X at the end. Therefore, the transformer X is attached to the utility pole Y. And since the holding | maintenance part 12 is provided with the arm part 121 which has insulation, the transformer X and the utility pole Y can be insulated.

また、本実施形態に係る変圧器装柱具は、アーム部121が撥水性を有するため、雨がアーム部121の表面に降ってもはじく。これにより、雨がアーム部121の表面に滞留して満たされるのを防止できるため、雨を介して変圧器Xと電柱Yとが導通するのを防止できる。したがって、降雨の際においても、変圧器Xと電柱Yとを確実に絶縁することができる。   Moreover, since the arm part 121 has water repellency, the transformer pillar according to the present embodiment is repelled even if rain falls on the surface of the arm part 121. Thereby, since it can prevent that rain accumulates on the surface of the arm part 121 and is filled, it can prevent that the transformer X and the utility pole Y conduct | electrically_connect through rain. Therefore, the transformer X and the utility pole Y can be reliably insulated even during rainfall.

また、本実施形態に係る変圧器装柱具は、固定部11に固定されるアーム部121が電柱Yから水平方向に突出して配置され、アーム部121の両端部に配置される係止部122が変圧器Xと係止することにより、変圧器Xが電柱Yに装着される。そして、アーム部121の全体が絶縁性を有して構成されると共に、アーム部121の表面が撥水性を有して構成されため、変圧器Xと電柱Yとを絶縁することができる。   In addition, in the transformer pillar according to the present embodiment, the arm part 121 fixed to the fixing part 11 is arranged to protrude from the utility pole Y in the horizontal direction, and the locking parts 122 are arranged at both ends of the arm part 121. , The transformer X is mounted on the utility pole Y. In addition, since the entire arm portion 121 is configured to have insulating properties and the surface of the arm portion 121 is configured to have water repellency, the transformer X and the utility pole Y can be insulated.

さらに、電柱Yが上方に向けてテーパ状に形成されているため、角筒状のアーム部121(の側面)が電柱Yの表面に沿って配置されることにより、アーム部121の上面が傾いて配置されている。したがって、アーム部121の上面に雨が降っても、雨がアーム部121の上面の傾きに伴って流れるため、雨がアーム部121の上面に滞留するのを防止できる。   Furthermore, since the electric pole Y is formed in a tapered shape toward the upper side, the upper surface of the arm part 121 is inclined by arranging the square cylindrical arm part 121 (side surface thereof) along the surface of the electric pole Y. Are arranged. Therefore, even if it rains on the upper surface of the arm part 121, the rain flows along with the inclination of the upper surface of the arm part 121, so that the rain can be prevented from staying on the upper surface of the arm part 121.

加えて、アーム部121が固定部11及び係止部122と着脱できるため、例えば、固定部11や係止部122と一体化しているアーム部121を製作する場合に対して、アーム部121の製作を容易にすることもできるため、生産効率を向上することができる。   In addition, since the arm part 121 can be attached to and detached from the fixing part 11 and the locking part 122, for example, when the arm part 121 integrated with the fixing part 11 and the locking part 122 is manufactured, Since production can be facilitated, production efficiency can be improved.

また、本実施形態に係る電柱装柱具は、筒状に形成されるアーム部121の内部に水平方向に沿って配置される長尺部材123が、固定部11と間隙を有して配置されるため、固定部11と係止部122とを絶縁させる。そして、アーム部121が折損した際には、係止部122を係止している長尺部材123が固定部11に係止されるため、アーム部121が折損するまでは、固定部11と係止部122、即ち、電柱Yと変圧器Xとを絶縁することができる一方、アーム部121が折損した際には、変圧器Xが脱落するのを防止できる。   Further, in the utility pole apparatus according to the present embodiment, the long member 123 arranged along the horizontal direction inside the arm portion 121 formed in a cylindrical shape is arranged with a gap from the fixed portion 11. Therefore, the fixing part 11 and the locking part 122 are insulated. And when the arm part 121 breaks, since the long member 123 which latches the latching part 122 is latched by the fixed part 11, until the arm part 121 breaks, the fixed part 11 and While the latching part 122, ie, the utility pole Y, and the transformer X can be insulated, it is possible to prevent the transformer X from falling off when the arm part 121 is broken.

具体的には、長尺部材は、変圧器Xが重力によりアーム部121を付勢する力に対抗すべく、アーム部121の内面に当接して配置される場合でもよい。かかる構成によれば、長尺部材がアーム部121の内面に当接して配置されているため、変圧器Xが重力によりアーム部121を付勢する力に対抗することができる。したがって、アーム部材121が欠損するのを防止できる。   Specifically, the long member may be disposed in contact with the inner surface of the arm portion 121 in order to counter the force that the transformer X biases the arm portion 121 by gravity. According to this configuration, since the long member is disposed in contact with the inner surface of the arm portion 121, the transformer X can counter the force that biases the arm portion 121 by gravity. Therefore, the arm member 121 can be prevented from being lost.
