Description

この発明は、PCカットアウト(高圧カットアウト)が破損した場合に、一時的に(仮に)送電を行うためのPCカットアウト用仮送電具に関する。   The present invention relates to a temporary power transmission device for PC cutout for temporarily (temporarily) transmitting power when a PC cutout (high voltage cutout) is damaged.

PCカットアウトは、蓋にヒューズ管が着脱自在に配設され、蓋を本体ケースに対して閉めることで、ヒューズ管が本体ケースに装着されるようになっている(例えば、特許文献1参照。)。このようなPCカットアウトのヒューズ管や蓋が焼損したり破損したりした場合、送電を仮復旧(応急仮送電)するためには、PCカットアウトの一次、二次側をバイパスするPDクランプを取り付けるか、PCカットアウトを取り替えなければならない。   In the PC cutout, a fuse tube is detachably disposed on a lid, and the fuse tube is attached to the main body case by closing the lid with respect to the main body case (see, for example, Patent Document 1). ). When such a PC cutout fuse tube or lid is burnt out or damaged, in order to temporarily restore power transmission (emergency temporary power transmission), a PD clamp that bypasses the primary and secondary sides of the PC cutout must be installed. Must be installed or the PC cutout replaced.

また、PDクランプを取り付ける際に仮支持を不要にし、かつ連続的に取付作業を行えるようにした技術が知られている(例えば、特許文献2参照。)。   In addition, a technique is known in which provisional support is not required when a PD clamp is attached, and the attachment operation can be performed continuously (see, for example, Patent Document 2).

特開2011−101500号公報JP 2011-101500 A 特開2000−209796号公報JP 2000-209796 A

ところで、PDクランプの取り付けやPCカットアウトの取り替えには、専門的な技術・技能を要し、しかも2名で作業を行わなければならず、時間と労力とを要する。特に、平常時には作業員がいるためすぐに対応が可能であるが、当直時や委託員対応時などには、PDクランプの取り付けなどが困難であり、応援等を要請しなければならない。このため、応急仮送電までに長時間を要していた。   By the way, the attachment of the PD clamp and the replacement of the PC cut-out require special techniques and skills, and two people have to work, requiring time and labor. In particular, it is possible to respond immediately because there are workers in normal times, but it is difficult to attach a PD clamp or the like when working on duty or when dealing with a contractor, and it is necessary to request support. For this reason, it took a long time until emergency temporary power transmission.

そこでこの発明は、PCカットアウトのヒューズ管や蓋が焼損・破損した場合に、容易かつ迅速に送電を仮復旧することを可能にするPCカットアウト用仮送電具を提供することを目的とする。   Accordingly, an object of the present invention is to provide a temporary power transmission device for PC cut-out that makes it possible to temporarily and easily restore power transmission when a PC cut-out fuse tube or lid is burnt or damaged. .

上記課題を解決するために、請求項1の発明は、PCカットアウトの本体ケースにヒューズ管を装着して仮送電するためのPCカットアウト用仮送電具であって、間接工具の共用操作棒の先端部に着脱自在に取り付けられ、前記共用操作棒を操作することで該共用操作棒から取り外し可能な被取付部と、前記被取付部と連結され、前記ヒューズ管を着脱自在に把持する把持部と、を備え、前記被取付部を前記共用操作棒の先端部に取り付け前記把持部で前記ヒューズ管を把持して、前記ヒューズ管を前記本体ケースに装着した後に、前記共用操作棒を前記被取付部から取り外すことで前記ヒューズ管を把持したままになる、ことを特徴とする。 In order to solve the above problems, the invention of claim 1 is a PC cutout temporary power transmission tool for temporarily transmitting power by attaching a fuse tube to a PC cutout main body case, and a common operation rod for an indirect tool. A detachably attached to the tip of the joint, and a detachable attachment portion that can be detached from the common operation rod by operating the common operation rod, and a grip that is connected to the attachment portion and detachably holds the fuse tube And attaching the attached portion to the tip of the common operation rod, grasping the fuse tube with the grasping portion, and attaching the fuse tube to the main body case, and then attaching the common operation rod to the main body case. The fuse tube is held by being detached from the attached portion .

この発明によれば、把持部でヒューズ管を把持した状態で、間接工具の共用操作棒の先端部に被取付部を取り付け、共用操作棒を操作してヒューズ管をPCカットアウトの本体ケース側に押し込むことで、ヒューズ管が本体ケースに装着される。次に、共用操作棒の先端部を被取付部から取り外すことで、本PCカットアウト用仮送電具で把持されたヒューズ管が、本体ケースに装着された応急仮送電状態となる。その後、応急仮送電が不要になった場合には、本PCカットアウト用仮送電具の被取付部に共用操作棒の先端部を取り付け、共用操作棒を引いてヒューズ管を本体ケースから取り外す。   According to the present invention, in the state where the fuse tube is gripped by the gripping portion, the attached portion is attached to the tip of the common operation rod of the indirect tool, and the fuse tube is attached to the PC case case side by operating the common operation rod. By pushing into the fuse tube, the fuse tube is attached to the main body case. Next, by removing the distal end portion of the common operation rod from the attached portion, the fuse tube gripped by the temporary power transmission tool for PC cutout becomes an emergency temporary power transmission state attached to the main body case. Thereafter, when emergency temporary power transmission becomes unnecessary, the tip of the common operation rod is attached to the attached portion of the temporary power transmission tool for PC cutout, and the fuse tube is removed from the main body case by pulling the common operation rod.

請求項1の発明によれば、把持部でヒューズ管を把持した本PCカットアウト用仮送電具を、共用操作棒の先端部に取り付け、地上などから共用操作棒でヒューズ管を押し込むだけで、ヒューズ管が本体ケースに装着される。そして、このような作業・操作は、誰でも一人で容易かつ迅速、安全に行うことができるため、PCカットアウトのヒューズ管や蓋が焼損・破損した場合であっても、容易かつ迅速に送電を仮復旧することが可能となる。   According to the invention of claim 1, the temporary power transmission tool for PC cutout holding the fuse tube with the holding portion is attached to the tip of the common operation rod, and the fuse tube is pushed with the common operation rod from the ground or the like. A fuse tube is attached to the case. And since such operations and operations can be performed easily, quickly and safely by one person, even if the PC cutout fuse tube or lid is burned or damaged, power can be transmitted easily and quickly. Can be temporarily restored.

また、本PCカットアウト用仮送電具が共用操作棒に対して着脱自在で、共用操作棒を操作することで該共用操作棒から取り外し可能なため、応急仮送電状態では本仮送電具でヒューズ管を把持したままにすることで、本仮送電具でヒューズ管を保護することができる。しかも、応急仮送電が不要になった際に、本仮送電具に再び共用操作棒を取り付けることで、容易かつ迅速に本仮送電具およびヒューズ管を取り外すことができる。
In addition, since the temporary power transmission tool for PC cut-out is detachable from the common operation rod and can be detached from the common operation rod by operating the common operation rod, the temporary power transmission device uses a fuse in the emergency temporary power transmission state. By holding the tube, the fuse tube can be protected by the temporary power transmission tool. Moreover, when temporary temporary power transmission is no longer necessary, the temporary power transmission tool and the fuse tube can be easily and quickly detached by attaching the common operation rod to the temporary power transmission tool again.

また、PDクランプを取り付ける場合には、高圧引下げ線にクランプ傷を付けてしまうが、本PCカットアウト用仮送電具による応急仮送電・仮復旧では、高圧引下げ線などに損傷を与えることがない。さらに、本復旧としてPCカットアウトを取り替える際に、PDクランプを取り付けた場合には、高圧引下げ線を切断しなければならないが、本仮送電具で仮復旧した場合には、高圧引下げ線を切断することなくヒューズ管を取り外すだけでよいため、容易かつ迅速、安全に取替作業を行うことができる。しかも、ヒューズ管の装着や取り外しは、上記のように1本の共用操作棒のみで行うことができる。   In addition, when a PD clamp is attached, the high-voltage pull-down line is damaged, but in the case of emergency temporary power transmission / temporary restoration using this PC cutout temporary power transmission device, the high-voltage pull-down line is not damaged. . Furthermore, when replacing the PC cut-out as the main restoration, if a PD clamp is attached, the high-voltage pull-down line must be cut. However, if the temporary power supply is temporarily restored, the high-voltage pull-down line is cut. Since it is only necessary to remove the fuse tube without having to do this, the replacement operation can be performed easily, quickly and safely. Moreover, the attachment and removal of the fuse tube can be performed with only one common operation rod as described above.

以下、この発明を図示の実施の形態に基づいて説明する。   The present invention will be described below based on the illustrated embodiments.

図1、2は、この発明の実施の形態に係るPCカットアウト用仮送電具1を示す正面図と平面図である。このPCカットアウト用仮送電具1は、PCカットアウトの本体ケースにヒューズ管100を装着して仮送電するための器具であり、主として、被取付部2と把持部3とを備えている。   1 and 2 are a front view and a plan view showing a temporary power transmission tool 1 for PC cutout according to an embodiment of the present invention. The PC cutout temporary power transmission tool 1 is an instrument for temporarily transmitting power by attaching a fuse tube 100 to a PC cutout main body case, and mainly includes a mounted portion 2 and a gripping portion 3.

被取付部2は、間接工具の共用操作棒の先端部に着脱自在に取り付けられる接続部であり、プラスチック・樹脂製で、図3に示すように、略円筒形となっている。すなわち、外円と同軸な円形の装着穴2aが下面から形成され、図4に示す共用操作棒200の共用連結部(先端部)201が嵌合可能となっている。ここで、間接工具とは、電線や電気機器などに作業者が直接接することなく作業を行うための工具であり、共用操作棒200の共用連結部201に各種の先端工具を取り付けることで、各種動作、操作が行えるものである。   The attached portion 2 is a connecting portion that is detachably attached to the distal end portion of the common operation rod of the indirect tool, and is made of plastic / resin and has a substantially cylindrical shape as shown in FIG. That is, a circular mounting hole 2a that is coaxial with the outer circle is formed from the lower surface, and the common connecting portion (tip portion) 201 of the common operation rod 200 shown in FIG. 4 can be fitted. Here, an indirect tool is a tool for an operator to perform work without directly contacting an electric wire or an electric device, and various types of tools can be obtained by attaching various tip tools to the common connecting portion 201 of the common operation rod 200. It can operate and operate.

被取付部2の外周面と装着穴2aの内周面との間には、第1の係合穴2bとガイド穴2cと第2の係合穴2dとが形成されている。第1の係合穴2bは、被取付部2の下端面2eから所定の長さだけ軸方向に沿って上方に延び、ガイド穴2cは、第1の係合穴2bの終端・上端から左右に水平に延びている。また、第2の係合穴2dは、ガイド穴2cの左右の終端から所定の長さだけ軸方向に沿って、下方に延びている。これらの第1の係合穴2bとガイド穴2cと第2の係合穴2dは、共用操作棒200の共用連結部201に設けられた係合突起202が、進入可能な幅に形成されている。このような第1の係合穴2bとガイド穴2cと第2の係合穴2dとが、被取付部2の軸心に対して点対照状に(180°回転させて)、2組形成されている。   A first engagement hole 2b, a guide hole 2c, and a second engagement hole 2d are formed between the outer peripheral surface of the mounted portion 2 and the inner peripheral surface of the mounting hole 2a. The first engagement hole 2b extends upward from the lower end surface 2e of the attached portion 2 along the axial direction by a predetermined length, and the guide hole 2c is left and right from the end / upper end of the first engagement hole 2b. It extends horizontally. The second engagement hole 2d extends downward along the axial direction by a predetermined length from the left and right ends of the guide hole 2c. The first engagement hole 2b, the guide hole 2c, and the second engagement hole 2d are formed so that the engagement protrusions 202 provided in the common connection portion 201 of the common operation rod 200 can enter the width. Yes. The first engagement hole 2b, the guide hole 2c, and the second engagement hole 2d are formed in two pairs in a point-contrast manner (rotated 180 °) with respect to the axis of the mounted portion 2. Has been.

ここで、係合突起202は、円柱状の共用連結部201の外周面から突出し、共用連結部201の軸心に対して点対照状に2つ設けられている。そして、係合突起202を第1の係合穴2bに位置させた状態で、共用連結部201を装着穴2aに挿入し、係合突起202がガイド穴2cに達した時点で、共用操作棒200を軸心周りに回転させ、係合突起202が第2の係合穴2dに達した時点で、共用操作棒200(共用連結部201)を引く。これにより、係合突起202が第2の係合穴2dに嵌合し、被取付部2が共用操作棒200に対して軸心回りに回転せず、軸方向にわずかにスライド可能に連結されるように、第1の係合穴2bとガイド穴2cと第2の係合穴2dとが形成されている。また、連結を解除するには、上記の連結操作と逆の操作・動作を行えばよい。   Here, the two engagement protrusions 202 protrude from the outer peripheral surface of the columnar shared connecting portion 201 and are provided in a point-contrast manner with respect to the axis of the shared connecting portion 201. Then, with the engagement protrusion 202 positioned in the first engagement hole 2b, the common connection portion 201 is inserted into the mounting hole 2a, and when the engagement protrusion 202 reaches the guide hole 2c, the common operation rod When the engagement protrusion 202 reaches the second engagement hole 2d, the common operation rod 200 (common connection portion 201) is pulled. As a result, the engagement protrusion 202 is fitted into the second engagement hole 2d, and the attached portion 2 is connected to the common operation rod 200 so as not to rotate about the axis but to be slightly slidable in the axial direction. Thus, a first engagement hole 2b, a guide hole 2c, and a second engagement hole 2d are formed. Moreover, what is necessary is just to perform operation and operation | movement contrary to said connection operation in order to cancel | release connection.

このような被取付部2の上端部から、2つのアーム部4が上方にV字状に延びるように形成されている。このアーム部4は、被取付部2と一体的に形成され、アーム部4とアーム部4の配設方向は、第1の係合穴2bと第1の係合穴2bとの配設方向に直交するように、設定されている。つまり、後述するようにして把持されたヒューズ管100の軸方向が、第1の係合穴2bと第1の係合穴2bとを結ぶ直線に直交するように、2つのアーム部4が形成されている。   Two arm portions 4 are formed so as to extend upward in a V shape from the upper end portion of the attached portion 2. The arm portion 4 is formed integrally with the mounted portion 2, and the disposition direction of the arm portion 4 and the arm portion 4 is the disposition direction of the first engagement hole 2b and the first engagement hole 2b. It is set to be orthogonal to That is, the two arm portions 4 are formed so that the axial direction of the fuse tube 100 gripped as will be described later is orthogonal to the straight line connecting the first engagement hole 2b and the first engagement hole 2b. Has been.

このようなアーム部4の先端部に、それぞれ把持部3が配設されている。つまり、アーム部4を介して、被取付部2と把持部3とが連結されている。この把持部3は、ヒューズ管100を着脱自在に把持するものであり、弾性変形自在な金属板で構成され、図5に示すように、接続部3aと把持円弧部3bとを有している。   The gripping portions 3 are disposed at the distal end portions of the arm portions 4 as described above. That is, the attached portion 2 and the grip portion 3 are connected via the arm portion 4. The grip portion 3 detachably grips the fuse tube 100 and is made of an elastically deformable metal plate, and has a connection portion 3a and a grip arc portion 3b as shown in FIG. .

接続部3aは、矩形のU字状で、アーム部4の先端部で覆われるようにして、アーム部4と接続されている。この接続部3aの両端から円弧状の把持円弧部3bが形成されている。この把持円弧部3bの曲率半径は、ヒューズ管100の主体100a(端子100bの根元部)の半径よりもやや小さく設定され、主体100aを把持した際に主体100aを確実に挟持し、かつ、把持したヒューズ管100を容易に外せるようになっている。   The connection portion 3 a is a rectangular U-shape and is connected to the arm portion 4 so as to be covered with the tip portion of the arm portion 4. An arc-shaped gripping arc portion 3b is formed from both ends of the connecting portion 3a. The radius of curvature of the gripping arc portion 3b is set to be slightly smaller than the radius of the main body 100a of the fuse tube 100 (the base portion of the terminal 100b), and when the main body 100a is gripped, the main body 100a is securely clamped and gripped. The fuse tube 100 can be easily removed.

また、この把持円弧部3bの上端部には、外側に広がった導入部3cが形成され、ヒューズ管100を把持円弧部3bに導入・挿入しやすいようになっている。さらに、このような把持部3は、被取付部2に対して点対照(左右対照)に配設され、ヒューズ管100を図1とは左右逆にしても把持できるようになっている。   In addition, an introduction portion 3c that spreads outward is formed at the upper end portion of the grip arc portion 3b, so that the fuse tube 100 can be easily introduced and inserted into the grip arc portion 3b. Further, such a gripping portion 3 is arranged in a point contrast (left-right contrast) with respect to the attached portion 2 so that the fuse tube 100 can be gripped even when left and right reversed from FIG.

次に、このような構成のPCカットアウト用仮送電具1の使用方法や応急仮送電方法などについて説明する。ここで、図6に示すように、PCカットアウト101の蓋102(蓋102に配設されているヒューズ管も)が破損し、本体ケース103は正常であるとする。   Next, a method of using the PC cutout temporary power transmission tool 1 having such a configuration, an emergency temporary power transmission method, and the like will be described. Here, as shown in FIG. 6, it is assumed that the lid 102 of the PC cutout 101 (and the fuse tube disposed on the lid 102) is damaged, and the main body case 103 is normal.

まず、本仮送電具1の把持部3で正常なヒューズ管100を把持する。すなわち、ヒューズ管100の主体100aを導入部3cから把持円弧部3b側に押し込むことで、両把持円弧部3bで主体100aを挟持、把持する。このとき、ヒューズ管100の端子100bがアーム部4に対向するように、ヒューズ管100を把持する。この状態で、間接工具の共用操作棒200の先端部に本仮送電具1を取り付ける。すなわち、上記のように、共用操作棒200の共用連結部201を被取付部2の装着穴2aに挿入し、共用操作棒200を軸心周りに回転させてから、引き寄せる。   First, the normal fuse tube 100 is gripped by the grip portion 3 of the temporary power transmission tool 1. That is, by pushing the main body 100a of the fuse tube 100 from the introducing portion 3c toward the gripping arc portion 3b, the main body 100a is sandwiched and gripped by both gripping arc portions 3b. At this time, the fuse tube 100 is held such that the terminal 100 b of the fuse tube 100 faces the arm portion 4. In this state, the temporary power transmission tool 1 is attached to the tip of the shared operation rod 200 for indirect tools. That is, as described above, the common connecting portion 201 of the common operation rod 200 is inserted into the mounting hole 2a of the attached portion 2, the common operation rod 200 is rotated around the axis, and then pulled.

次に、地上などから共用操作棒200を操作して、ヒューズ管100をPCカットアウト101の本体ケース103側に押し込み、ヒューズ管100の端子100bを本体ケース103内のソケットに挿入する。これにより、ヒューズ管100が本体ケース103に装着される。続いて、共用操作棒200を本仮送電具1から取り外す。すなわち、上記のように、共用操作棒200を押して軸心周りに回転させ、係合突起202を第1の係合穴2bに位置させて、共用連結部201を装着穴2aから引き出す。なお、この取り外しや上記の取り付けの際に、共用操作棒200を動かす代わりに、本仮送電具1を動かしてもよいことは勿論である。   Next, the common operation rod 200 is operated from the ground or the like, the fuse tube 100 is pushed into the main body case 103 side of the PC cutout 101, and the terminal 100b of the fuse tube 100 is inserted into the socket in the main body case 103. As a result, the fuse tube 100 is attached to the main body case 103. Subsequently, the common operation rod 200 is removed from the temporary power transmission tool 1. That is, as described above, the common operation rod 200 is pushed and rotated around the axis, the engagement protrusion 202 is positioned in the first engagement hole 2b, and the common connection portion 201 is pulled out from the mounting hole 2a. Needless to say, the temporary power transmission tool 1 may be moved instead of moving the common operation rod 200 during the removal or the attachment.

これにより、本仮送電具1で把持されたヒューズ管100が、本体ケース103に装着され、応急仮送電状態となる。ここで、応急仮送電状態であることを明示するために、本仮送電具1などに「仮送電中」の表示ラベルなどを貼り付けてもよい。   As a result, the fuse tube 100 held by the temporary power transmission tool 1 is attached to the main body case 103, and an emergency temporary power transmission state is established. Here, in order to clearly indicate that the emergency temporary power transmission state is set, a display label of “temporary power transmission” or the like may be attached to the temporary power transmission tool 1 or the like.

その後、応急仮送電が不要になった場合には、上記と同様にして本仮送電具1の被取付部2に共用操作棒200の共用連結部201を接続し、共用操作棒200を引いてヒューズ管100を本体ケース103から取り外す。その後、ヒューズ管100を把持部3から取り外すものである。   Thereafter, when emergency temporary power transmission is no longer necessary, the common connection portion 201 of the common operation rod 200 is connected to the mounted portion 2 of the temporary power transmission device 1 in the same manner as described above, and the common operation rod 200 is pulled. The fuse tube 100 is removed from the main body case 103. Thereafter, the fuse tube 100 is removed from the grip portion 3.

以上のように、このPCカットアウト用仮送電具1によれば、把持部3でヒューズ管100を把持した本仮送電具1を、共用操作棒200の先端部に取り付け、地上などから共用操作棒200でヒューズ管100を押し込むだけで、ヒューズ管100が本体ケース103に装着される。そして、このような作業・操作は、誰でも一人で容易かつ迅速、安全に行うことができるため、PCカットアウト101の蓋102が焼損・破損した場合であっても、容易かつ迅速に送電を仮復旧することが可能となる。   As described above, according to the temporary power transmission tool 1 for PC cutout, the temporary power transmission tool 1 that holds the fuse tube 100 with the grip portion 3 is attached to the distal end portion of the common operation rod 200 and shared operation is performed from the ground or the like. The fuse tube 100 is attached to the main body case 103 simply by pushing the fuse tube 100 with the rod 200. Since such operations and operations can be performed easily, quickly, and safely by one person, even if the lid 102 of the PC cutout 101 is burned or damaged, power can be transmitted easily and quickly. Temporary recovery is possible.

また、本仮送電具1が共用操作棒200に対して着脱自在なため、応急仮送電状態では上記のように本仮送電具1でヒューズ管200を把持したままにすることで、本仮送電具1でヒューズ管100を保護することができる。しかも、応急仮送電が不要になった際に、本仮送電具1に再び共用操作棒200を接続することで、容易かつ迅速に本仮送電具1およびヒューズ管100を取り外すことができる。   Further, since the temporary power transmission tool 1 is detachable from the common operation rod 200, the temporary power transmission can be performed by holding the fuse tube 200 with the temporary power transmission tool 1 as described above in the emergency temporary power transmission state. The fuse tube 100 can be protected by the tool 1. In addition, when temporary temporary power transmission becomes unnecessary, the temporary power transmission tool 1 and the fuse tube 100 can be easily and quickly removed by connecting the common operation rod 200 to the temporary power transmission tool 1 again.

また、PDクランプを取り付ける場合には、高圧引下げ線にクランプ傷を付けてしまうが、本仮送電具1による応急仮送電・仮復旧では、高圧引下げ線などに損傷を与えることがない。さらに、本復旧としてPCカットアウトを取り替える際に、PDクランプを取り付けた場合には、高圧引下げ線を切断しなければならないが、本仮送電具1で仮復旧した場合には、高圧引下げ線を切断することなくヒューズ管100を取り外すだけでよいため、容易かつ迅速、安全に取替作業を行うことができる。しかも、ヒューズ管100の装着や取り外しは、上記のように1本の共用操作棒200のみで行え、少ない設備、人員で行うことができる。また、限流ヒューズの形状、大きさがヒューズ管100と同等の場合には、本仮送電具1を使用して限流ヒューズを取り替えることができ、事故・停電などがトランスによるものか否かを確認することが可能となる。   In addition, when the PD clamp is attached, the high voltage pull-down line is damaged by the clamp, but the temporary temporary power transmission / temporary restoration by the temporary power transmission tool 1 does not damage the high voltage pull-down line. In addition, when replacing the PC cutout as the main restoration, if a PD clamp is attached, the high voltage pull-down line must be cut off. Since it is only necessary to remove the fuse tube 100 without cutting, the replacement operation can be performed easily, quickly and safely. Moreover, the mounting and removal of the fuse tube 100 can be performed with only one common operation rod 200 as described above, and can be performed with few facilities and personnel. If the current limiting fuse has the same shape and size as the fuse tube 100, the current limiting fuse 1 can be used to replace the current limiting fuse, and whether or not an accident or power failure is caused by a transformer. Can be confirmed.
