Description

この発明は、ガス絶縁開閉装置に使用される電圧変成器のコイルを巻回する電圧変成器コイルの巻線装置に関するものである。   The present invention relates to a voltage transformer coil winding device for winding a voltage transformer coil used in a gas insulated switchgear.

ガス絶縁開閉装置に使用される電圧変成器は、例えば図6、図7のように構成されている。図6は一部透視した構造図であり、図7はコイルの一部を断面で示したコイル構造図である。
この構成のコイル1は、絶縁筒で構成された巻心2の周囲に直径の細い絶縁被覆電線のコイル線材3を密着巻多層構造とし、各層間に絶縁フィルムの層間絶縁材4が挿入され、断面が台形形状に形成されている。コイル1の外周部には電界集中が生じないようにシールド5が取り付けられ、図6のように密閉容器6の中に収容され、ガス絶縁開閉装置との接続部には絶縁スペーサ7が設けられ、内部には絶縁ガスが封入されて使用される。
図7のような断面が台形形状のコイルを巻回する巻線装置としては、例えば特許文献1に台形コイルの製造方法として開示されている。
特許文献1の台形コイルの製造方法は、コイルが巻回されて直径が大きくなるにつれて狭くなる巻幅に対応して層間絶縁の絶縁フィルムの幅が狭くなるように両側を切断してコイル表面に供給する方法を採っている。
The voltage transformer used for the gas insulated switchgear is configured as shown in FIGS. 6 and 7, for example. FIG. 6 is a partially transparent structure diagram, and FIG. 7 is a coil structure diagram showing a part of the coil in cross section.
The coil 1 having this configuration has a coiled wire material 3 of an insulation-coated electric wire having a small diameter around a winding core 2 made of an insulating cylinder, and has a closely wound multilayer structure, and an interlayer insulating material 4 of an insulating film is inserted between each layer. The cross section is formed in a trapezoidal shape. A shield 5 is attached to the outer peripheral portion of the coil 1 so as not to cause electric field concentration, and is housed in a sealed container 6 as shown in FIG. 6, and an insulating spacer 7 is provided at a connection portion with the gas insulated switchgear. The inside is filled with an insulating gas.
As a winding apparatus for winding a coil having a trapezoidal cross section as shown in FIG. 7, for example, Patent Document 1 discloses a method for manufacturing a trapezoidal coil.
The manufacturing method of the trapezoidal coil of patent document 1 cut | disconnects both sides so that the width | variety of the insulating film of an interlayer insulation may become narrow corresponding to the winding width | variety which becomes narrow as a coil is wound and a diameter becomes large, and it is on the coil surface. The supply method is taken.

この構成では、コイル部分の外径が大きくなるにしたがって幅を狭くした絶縁フィルムを供給することにより、コイル端面がテーパ状に巻き上げられ、巻回後に加工を行うことなく断面が台形形状に仕上げることができるものである。   In this configuration, by supplying an insulating film with a reduced width as the outer diameter of the coil portion increases, the coil end surface is wound up in a tapered shape, and the cross section is finished in a trapezoidal shape without processing after winding. It is something that can be done.

また、層間絶縁の絶縁テープを供給するときには、巻回される各層毎にコイル巻心の軸に対して直角方向の所定の位置に供給されなければならないが、コイルの所定の位置に正しく供給される層間絶縁の供給方法としては、例えば特許文献2に開示されている。
特許文献2の絶縁テープの供給方法は、1層巻終える毎にコイルの表面に絶縁テ−プの先端を片面粘着テープ小片により貼付ローラを用いて貼付け、巻心を回転し絶縁テープを巻き付ける方法が示されている。
In addition, when supplying insulating tape for interlayer insulation, each layer to be wound must be supplied to a predetermined position in a direction perpendicular to the axis of the coil core, but supplied correctly to a predetermined position of the coil. For example, Patent Document 2 discloses a method for supplying interlayer insulation.
The method of supplying the insulating tape disclosed in Patent Document 2 is a method in which the end of the insulating tape is attached to the surface of the coil with a single-sided adhesive tape using a sticking roller every time one layer of winding is completed, and the insulating tape is wound by rotating the winding core. It is shown.

電圧変成器コイルの各巻回層の間に挿入される絶縁層として1台に使用される層間絶縁材の使用量は、巻回するコイルの種類により異なる。層間絶縁材の購入単位は、層間絶縁材ロール支持台への装着が容易な大きさを設定しており、コイル1の1台の使用量とは一致しないので、巻回中には材料切れが生じる。巻回中に材料切れが生じた場合には、巻回動作を一時停止して補充する必要がある。
特許文献1および特許文献2では、層間絶縁材の補充方法については何ら開示されていないが、実際に巻線装置に材料切れが発生したときには、オペレータが巻線装置の巻回動作を一時停止し、層間絶縁材の掛け替えを行って巻回を続行するものと想定される。
電圧変成器コイルの巻回作業の自動化を図る場合には、巻線装置を停止することなく連続的に動作させることが巻線装置の稼働率を最良状態とすることであるが、コイル線材および層間絶縁材に材料切れが生じたときに自動的に巻回動作を一時停止することになり、巻線装置の稼働率が低下する問題点がある。
この発明は、上記問題点を解消するためになされたものであり、層間絶縁材の材料切れが生じた場合に、速やかに補充し、巻線装置の稼働率の低下を最小限に抑えられる巻線装置を提供することを目的とする。
The amount of interlayer insulating material used as one insulating layer inserted between each winding layer of the voltage transformer coil varies depending on the type of coil to be wound. The unit of purchase of the interlayer insulating material is set to a size that can be easily mounted on the interlayer insulating material roll support base, and does not match the amount of one coil 1 used. Arise. When material runs out during winding, the winding operation needs to be temporarily stopped and replenished.
Patent Document 1 and Patent Document 2 do not disclose any method for replenishing the interlayer insulating material. However, when a material shortage actually occurs in the winding device, the operator temporarily stops the winding operation of the winding device. It is assumed that winding is continued by changing the interlayer insulating material.
When automating the winding operation of the voltage transformer coil, continuous operation without stopping the winding device is to obtain the best operating rate of the winding device. When the material of the interlayer insulating material is cut, the winding operation is automatically stopped temporarily, and there is a problem that the operating rate of the winding device is lowered.
The present invention has been made in order to solve the above-described problems. When the material of the interlayer insulating material runs out, it can be quickly replenished to minimize the decrease in the operating rate of the winding device. An object is to provide a wire device.

この発明に係る電圧変成器コイルの巻線装置は、巻心にコイル線材を巻回するコイル巻回機構と、層間絶縁材ロールを支持する層間絶縁材ロール支持台と、層間絶縁材を所定の幅および長さに裁断してコイル巻回機構側に供給する層間絶縁材供給手段と、所定寸法に裁断された層間絶縁材の先端部を巻回中のコイルの表面に案内してコイルの巻回層間に挿入する層間絶縁材挿入手段と、コイル巻回機構と上記層間絶縁材供給手段との間に配置され、摺動枠の上部に転向ロール、上記摺動枠に上下動可能に支持され上記層間絶縁材に所定の張力となるように上下動する揺動ロールを備えたダンサーローラ機構と、コイル巻回機構、層間絶縁材供給手段、層間絶縁材挿入手段および上記ダンサーローラ機構を制御する制御装置とを備え、
層間絶縁材ロールを層間絶縁材ロール支持台に装着し、ダンサーローラ機構および層間絶縁材供給手段に層間絶縁材を挿通し、挿通した層間絶縁材を停止して揺動ロールを低位置に下降させ、層間絶縁材ロール支持台に支持された層間絶縁材ロールを一回転逆転させたときの揺動ロールの高さ変化量を検出し、制御装置は、検出された上記揺動ロールの高さ変化量から上記層間絶縁材ロールの外径を求めて層間絶縁材ロールの長さ残量を算出し、コイルの巻回可能層数を算出して表示するように構成したものである。
A winding device for a voltage transformer coil according to the present invention includes a coil winding mechanism that winds a coil wire around a winding core, an interlayer insulating material roll support that supports an interlayer insulating material roll, Interlayer insulating material supply means for cutting the width and length into the coil winding mechanism and the tip of the interlayer insulating material cut to a predetermined size are guided to the surface of the coil being wound to wind the coil. It is arranged between the interlayer insulating material inserting means for inserting between the rotating layers, the coil winding mechanism and the interlayer insulating material supplying means, and is supported on the upper part of the sliding frame so as to be movable up and down on the sliding frame. A dancer roller mechanism having a swing roll that moves up and down so as to have a predetermined tension on the interlayer insulation material, a coil winding mechanism, an interlayer insulation material supply means, an interlayer insulation material insertion means, and the dancer roller mechanism are controlled.

The amount of change in the height of the swing roll when the interlayer insulation roll supported by the interlayer insulation roll support is reversed by one rotation is detected, and the control device detects the change in the detected height of the swing roll. The outer diameter of the interlayer insulating material roll is obtained from the amount, the remaining length of the interlayer insulating material roll is calculated, and the number of layers in which the coil can be wound is calculated and displayed.

電圧変成器コイル巻線装置を上記のように構成すると、層間絶縁材ロールが楕円状に巻回されていても、層間絶縁材の長さ残量が正確に把握することができる。
また、最初に巻回する電圧変成器コイル1台分の層間絶縁材を装着しなくても、予め材料切れとなる巻回層数が明確に表示されるので、巻回途中で層間絶縁材の材料切れが生じたときに、効率よく材料補充を行い巻線装置の稼働率の低下を抑えることができる。
さらに、残量の少ない層間絶縁材ロールでも躊躇なく使い切ることができ、層間絶縁材の端材の発生を殆どなくすることができる。
When the voltage transformer coil winding device is configured as described above, the remaining length of the interlayer insulating material can be accurately grasped even if the interlayer insulating material roll is wound in an elliptical shape.
In addition, since the number of winding layers that will run out of material is clearly displayed in advance without mounting an interlayer insulating material for one voltage transformer coil to be wound first, When the material runs out, the material can be efficiently replenished to prevent a reduction in the operating rate of the winding device.
Furthermore, even an interlayer insulating material roll with a small remaining amount can be used up without any problem, and generation of an end material of the interlayer insulating material can be almost eliminated.

The interlayer insulating material supply means 30 is arranged at the upper part of the moving carriage 20, and the interlayer insulating material insertion means 40 is arranged at the lower part of the interlayer insulating material supply means 30 of the moving carriage 20, and the moving carriage 20 supports the rail 21 on the coil 21. It is configured to be movable back and forth by the drive mechanism 22 in the direction of the table 11.

コイル巻回機構10は、巻心2を装着してコイル線材3を巻回するコイル支持台11と、コイル線材3が巻かれているコイル線材ドラム3aを支持するコイル線材支持台13と、コイル線材3をコイル支持台11の方向に案内するガイド車輪15と、コイル線材3を巻回中コイル1の外径部の巻回位置に案内する線材案内機構16とで構成されている。   The coil winding mechanism 10 includes a coil support base 11 for mounting the winding core 2 and winding the coil wire 3, a coil wire support base 13 for supporting the coil wire drum 3 a around which the coil wire 3 is wound, and a coil A guide wheel 15 that guides the wire 3 toward the coil support 11 and a wire guide mechanism 16 that guides the coil wire 3 to the winding position of the outer diameter portion of the coil 1 during winding.

層間絶縁材供給機構30は、層間絶縁材4をコイル巻回機構10へ移送して巻回中のコイル1の表面に供給する供給テーブル31と、層間絶縁材ロール支持台14に懸架された層間絶縁材ロール4aから層間絶縁材4を供給テーブル31上に供給する案内ロール32と、供給される層間絶縁材4の送り速度を調整し、必要により所定の位置で停止するブレーキロール33と、層間絶縁材4を所定の幅に幅切りする幅切りカッタ34と、幅切りされた層間絶縁材4を供給テーブル31の所定の位置を通過させるように案内するガイドロール35と、層間絶縁材4に設定された長さの送りをかける送りロール36と、送り出された層間絶縁材4の先端部を下向きに転向する転向ロール37と、層間絶縁材4を所定の長さで切断する横切りカッタ38と、送り出された層間絶縁材4の先端部に圧縮エアーを吹き付ける吹付ノズル39とを備えている。   The interlayer insulating material supply mechanism 30 includes a supply table 31 that transfers the interlayer insulating material 4 to the coil winding mechanism 10 and supplies it to the surface of the coil 1 being wound, and an interlayer suspended on the interlayer insulating material roll support 14. A guide roll 32 that supplies the interlayer insulating material 4 from the insulating material roll 4a onto the supply table 31, a brake roll 33 that adjusts the feed speed of the supplied interlayer insulating material 4 and stops at a predetermined position if necessary, an interlayer A width cutting cutter 34 for cutting the insulating material 4 into a predetermined width, a guide roll 35 for guiding the cut interlayer insulating material 4 through a predetermined position of the supply table 31, and an interlayer insulating material 4 A feed roll 36 that feeds a set length, a turning roll 37 that turns the tip of the delivered interlayer insulating material 4 downward, and a transverse cutter 3 that cuts the interlayer insulating material 4 by a predetermined length When, and a spray nozzle 39 for blowing fed compressed air at the tip portion of the interlayer insulator 4.

供給テーブル31は、平板状に形成すると、通過する層間絶縁材4が摩擦によって静電気を発生し、供給テーブル31と層間絶縁材4が吸着し、層間絶縁材4が円滑に供給されなくなる問題があるので、図2に示すように層間絶縁材4の供給方向に複数のV溝を設けた形状に形成している。このように構成すれば、供給テーブル31の上面と層間絶縁材4との間の接触面積が少なくなって静電気の発生が抑制され、層間絶縁材4が円滑に供給できるようになる。   When the supply table 31 is formed in a flat plate shape, the passing interlayer insulation material 4 generates static electricity due to friction, the supply table 31 and the interlayer insulation material 4 are adsorbed, and the interlayer insulation material 4 cannot be supplied smoothly. Therefore, as shown in FIG. 2, a plurality of V grooves are formed in the supply direction of the interlayer insulating material 4. If comprised in this way, the contact area between the upper surface of the supply table 31 and the interlayer insulation material 4 will decrease, generation | occurrence | production of static electricity will be suppressed, and the interlayer insulation material 4 will be able to be supplied smoothly.

層間絶縁材挿入手段40は、層間絶縁材4の先端部を吸着して所定の位置に案内する吸着部材41と、層間絶縁材4の先端部を巻回中のコイル1の表面に加熱接着する加熱ロールで構成された加熱手段42と、この加熱手段42を前後に移動可能に支持するクランク43と、加熱手段42を巻回中のコイル1の表面に適正圧力で押し付ける押圧シリンダ44とを備えている。   The interlayer insulating material inserting means 40 heat-bonds the tip of the interlayer insulating material 4 to the surface of the coil 1 being wound with the suction member 41 that sucks and guides the tip of the interlayer insulating material 4 to a predetermined position. A heating means 42 composed of a heating roll, a crank 43 that supports the heating means 42 so as to be movable back and forth, and a pressing cylinder 44 that presses the heating means 42 against the surface of the coil 1 being wound with an appropriate pressure. ing.

吸着部材41は、図3に示すように、中空状に形成し、吸着面に複数の吸着孔41aを横方向に等間隔に設け、真空引きする真空引口41bを設けた構成としている。
吸着部材41の内部を真空状態にすると、吸着孔41aに層間絶縁材4が近接すると吸着し、吸着部材41aを下方に引き下げると層間絶縁材4に張力を与えることができる。

When the inside of the adsorbing member 41 is in a vacuum state, the adsorbing member 41 adsorbs when the interlayer insulating material 4 comes close to the adsorbing hole 41a, and pulls the adsorbing member 41a downward to apply tension to the interlayer insulating material 4.

スクラップ排出手段50は、層間絶縁材4が幅切りカッタ34で所定の幅に幅切りしたときに発生するスクラップを排出するものであり、スクラップ排出ダクト51と、スクラップをスクラップ排出ダクト51内に案内する圧縮エアーを吹き込む圧縮エアー吹込手段52と、スクラップを収容するスクラップ容器53とで構成されている。
スクラップ容器53は廃棄処理が容易な位置に配置し、スクラップ排出ダクト51は、一方の端部を左右一対の幅切りカッタ34のそれぞれの上部に配置できるように2方に分岐して2つの入口側開口部を設け、各入口側開口部を左右両側の幅切りカッタ34のそれぞれの上部に配置し、他方の端部は出口側開口部としてスクラップ容器53内に開口するように配置し、入口側開口部から圧縮エアー吹き込み手段52により圧縮エアーを吹き込む構成である。
The scrap discharging means 50 is for discharging scrap generated when the interlayer insulating material 4 is cut to a predetermined width by the width cutting cutter 34, and guides the scrap discharging duct 51 and the scrap into the scrap discharging duct 51. Compressed air blowing means 52 for blowing compressed air and a scrap container 53 for storing scrap.
The scrap container 53 is disposed at a position where disposal is easy, and the scrap discharge duct 51 is bifurcated in two directions so that one end can be disposed at the upper part of each of the pair of left and right width-cutting cutters. A side opening is provided, each inlet side opening is disposed at the upper part of each of the width-cutting cutters 34 on both the left and right sides, and the other end is disposed as an outlet side opening so as to open into the scrap container 53. The compressed air is blown by the compressed air blowing means 52 from the side opening.

ダンサーローラ機構60は、層間絶縁材ロール支持台14と層間絶縁材供給手段30および層間絶縁材挿入手段40が装着された移動台車20の間に配置され、層間絶縁材供給手段30に供給される層間絶縁材4に適正な張力を与えるものであり、摺動枠61と、摺動枠61の上部に装着された転向ロール63と、摺動枠61に上下に摺動可能に装着された揺動ロール62で構成され、揺動ロール62は層間絶縁材4に適正な張力が与えられる重量に調整されている。摺動枠61には揺動ロール62の高さ位置が検出できるように高さ検出手段が装備されている。   The dancer roller mechanism 60 is disposed between the interlayer insulating material roll support 14 and the movable carriage 20 on which the interlayer insulating material supplying means 30 and the interlayer insulating material inserting means 40 are mounted, and is supplied to the interlayer insulating material supplying means 30. Appropriate tension is applied to the interlayer insulating material 4. The sliding frame 61, the turning roll 63 mounted on the upper portion of the sliding frame 61, and the swing mounted on the sliding frame 61 so as to be slidable up and down. The movable roll 62 is configured such that the swing roll 62 is adjusted to a weight that allows the interlayer insulating material 4 to be provided with an appropriate tension. The sliding frame 61 is equipped with a height detecting means so that the height position of the swing roll 62 can be detected.

このように構成された電圧変成器コイルの巻線装置では、巻回するコイル1の仕様値および巻回条件を図示しない制御装置に入力しておくことで、各部が動作する。
巻回作業はまず、電圧変成器コイルの巻線仕様を制御装置にインプットし、巻線材料のコイル線材ドラム3aをコイル線材支持台13に、層間絶縁材ロール4aを層間絶縁材ロール支持台14に懸架してし、巻心2をコイル支持台11に装着し、コイル支持台13からコイル線材3の端部をガイド車輪15、線材案内機構16を通過させるように掛けて巻心2に巻き付ける。
次に、層間絶縁材4を層間絶縁材ロール支持台14からダンサーローラ機構60に通し、案内ロール32、ブレーキロール33、ガイドロール35、送りロール36、横切りカッタ38、転向ロール37を経由して吸着部材41の近くまで挿通させる。
In the voltage transformer coil winding device configured as described above, each part operates by inputting the specification value and winding condition of the coil 1 to be wound into a control device (not shown).
First, the winding specification of the voltage transformer coil is input to the control device, the coil wire drum 3a of the winding material is input to the coil wire support 13 and the interlayer insulating roll 4a is connected to the interlayer insulating roll support 14. The winding core 2 is mounted on the coil support base 11 and the end of the coil wire 3 is hung from the coil support base 13 so as to pass through the guide wheel 15 and the wire guide mechanism 16 and wound around the core 2. .
Next, the interlayer insulating material 4 is passed from the interlayer insulating material roll support 14 to the dancer roller mechanism 60, and passed through the guide roll 32, the brake roll 33, the guide roll 35, the feed roll 36, the crossing cutter 38, and the turning roll 37. It is inserted to the vicinity of the adsorption member 41.

次にダンサーロール機構60によって層間絶縁材ロール4aの残量を求める方法について説明する。図4はダンサーロール機構60の層間絶縁材ロール4aの残量測定するときのダンサーローラ機構60の動作説明図である。
層間絶縁材4を層間絶縁材供給機構30に挿通した状態でブレーキロール33によって層間絶縁材4が移動しないように固定し、ダンサーロール機構60の揺動ロール62を最下部まで下降し、層間絶縁材ロール支持台14の層間絶縁材ロール4aを1回転逆転し、揺動ロール62の高さ変化量Hを検出して制御装置に入力する。
制御装置は、検出した揺動ロール62の高さ変化量Hから層間絶縁材ロール4aの外径を算出し、この外径と層間絶縁材の巻心直径および層間絶縁材4の厚さから層間絶縁材の長さを求め、求めた層間絶縁材の長さで巻回できる巻回可能層数を演算し、オペレータが読みとれるように表示するとともに、巻回可能層数に達したときには巻回動作を一時停止し、層間絶縁材の材料切れ警報を出力する。
Next, a method for obtaining the remaining amount of the interlayer insulating material roll 4a by the dancer roll mechanism 60 will be described. FIG. 4 is an explanatory view of the operation of the dancer roller mechanism 60 when the remaining amount of the interlayer insulating material roll 4a of the dancer roll mechanism 60 is measured.
The interlayer insulating material 4 is fixed so that the interlayer insulating material 4 does not move by the brake roll 33 while the interlayer insulating material 4 is inserted into the interlayer insulating material supply mechanism 30, and the swing roll 62 of the dancer roll mechanism 60 is lowered to the lowermost position. The inter-layer insulating material roll 4a of the material roll support 14 is reversed once and the height change amount H of the swing roll 62 is detected and input to the control device.
The control device calculates the outer diameter of the interlayer insulating material roll 4 a from the detected height change amount H of the swing roll 62, and calculates the interlayer from the outer diameter, the core diameter of the interlayer insulating material, and the thickness of the interlayer insulating material 4. Calculate the length of the insulating material, calculate the number of windable layers that can be wound with the calculated length of the interlayer insulating material, display it so that the operator can read it, and wind it when the number of windable layers is reached Pauses the operation and outputs an interlayer insulation material out warning.

コイル巻回機構10では、線材案内機構16がコイル線材3を密着巻きする線径に相当するピッチで移動して巻回位置に案内する。各層の巻回数を巻回するとコイル巻回機構10が停止する。また、巻回中にコイル線材3が断線したときには、断線位置でコイル巻回機構10の巻回動作を一時停止する。コイル線材3の断線により巻回動作が停止すると、コイル線材3を接続する。   In the coil winding mechanism 10, the wire guide mechanism 16 moves at a pitch corresponding to the wire diameter for tightly winding the coil wire 3 and guides it to the winding position. When the number of turns of each layer is wound, the coil winding mechanism 10 stops. Further, when the coil wire 3 is disconnected during winding, the winding operation of the coil winding mechanism 10 is temporarily stopped at the disconnection position. When the winding operation is stopped due to the disconnection of the coil wire 3, the coil wire 3 is connected.

層間絶縁材供給機構30では、所定の幅に幅切りされた層間絶縁材4の先端部が吸着部材41の吸着部に近接位置まで供給する。層間絶縁材4は図4に示す手順の通りに動作して層間絶縁材4がコイル線材3とともに所定の巻回数が巻回されて次の層の密着巻が行われる。この動作が層毎に繰り返されてコイル1が巻回される。   In the interlayer insulating material supply mechanism 30, the front end portion of the interlayer insulating material 4 cut into a predetermined width supplies the suction portion of the suction member 41 to the proximity position. The interlayer insulating material 4 operates according to the procedure shown in FIG. 4, and the interlayer insulating material 4 is wound a predetermined number of turns together with the coil wire 3, so that the next layer is tightly wound.
