Description

本発明は、制御装置を制御盤によって制御しているとき、活線状態のまま制御盤を新規のものに更新する制御盤の更新方法に関する。   The present invention relates to a control panel updating method for updating a control panel to a new one in a live line state when the control device is controlled by the control panel.

従来の制御盤更新方法は、既設の配線を一本一本調査し、切り替えの中継盤を準備して、中継ケーブルによる仮設配線を行い、中継盤で既設制御盤側、新設制御盤側と制御する側を変えていた。また、制御盤の切り替えの試運転が完了したら中継盤および仮設仮設配線を撤去していた。
図４は従来の制御盤更新方法を適用した設備の配線を示す図である。
１は既設制御盤、１１は新設制御盤、１２は中継盤、５は制御装置と既設制御盤間の配線、１３は既設制御盤１、新設制御盤１１、中継盤１２を接続する中継ケーブルである。この図に示すように、既設制御盤１、新設制御盤１１と制御装置間の配線は、一旦中継盤１２を経由して行い、既設制御盤１での制御と新設制御盤１１での制御の切り替えを中継盤１２の接点を開閉することで行い、新設制御盤１１での動作確認後、中継盤１２、中継ケーブル１３を撤去していた。 The conventional control panel update method investigates existing wiring one by one, prepares a switching relay panel, performs temporary wiring with a relay cable, and controls the existing control panel side and the new control panel side with the relay panel. The side to do was changed. In addition, when the test operation for switching the control panel was completed, the relay panel and the temporary temporary wiring were removed.
FIG. 4 is a diagram showing wiring of equipment to which a conventional control panel updating method is applied.
1 is an existing control panel, 11 is a new control panel, 12 is a relay panel, 5 is a wiring between the control device and the existing control panel, 13 is a relay cable for connecting the existing control panel 1, the new control panel 11 and the relay panel 12 is there. As shown in this figure, the wiring between the existing control panel 1, the new control panel 11 and the control device is once performed via the relay panel 12, and the control of the existing control panel 1 and the control of the new control panel 11 are performed. The switching is performed by opening and closing the contact point of the relay panel 12, and after confirming the operation on the new control panel 11, the relay panel 12 and the relay cable 13 are removed.

図５は従来の制御盤更新方法の手順を示すフローチャートである。制御盤の更新は以下の手順で行われていた。
ステップ１（Ｓ１１）：２接点の中継盤を準備し、閉じたａ接点両端から２本の中継ケーブルを稼動中の既設制御盤に導く。
ステップ２（Ｓ１２）：２本の中継ケーブルの先端を、直スリーブ接続により、間をおいて稼動中の既設制御盤に入る配線に接続する。

従来の工法は、切り替えの際に中継盤と中継ケーブルを使用し、一旦仮設配線を行い、既設のケーブルを分離し、その状態で動作を確認する。更に動作確認後、その仮設配線を撤去するため、コスト、工数が大きくなるという問題があった。また中継盤が必要となるのでスペースの面での制約が大きいという問題もあった。
本発明はこのような問題点に鑑みてなされたものであり、コスト、工数を削減し、スペースの制約を受けない制御盤更新方法を提供することを目的とする。 The conventional method uses a relay panel and a relay cable at the time of switching, temporarily performs temporary wiring, separates the existing cable, and confirms the operation in that state. Furthermore, since the temporary wiring is removed after confirming the operation, there is a problem that the cost and the man-hour increase. In addition, since a relay panel is required, there is a problem that the space is very limited.
The present invention has been made in view of such problems, and an object of the present invention is to provide a control panel updating method that reduces costs and man-hours and is not subject to space constraints.

上記問題を解決するため、本発明の制御盤更新方法は、既設制御盤と、その既設制御盤によって制御される制御装置と、前記既設制御盤と前記制御装置を接続する多数の配線とで構成する稼動中のシステムにおいて、次の手順によって前記既設制御盤を新設制御盤に入れ替えることを特徴とするものである。
ステップ１：断路端子台を備えた前記新設制御盤を前記既設制御盤と同一の電気室のスペースに設置し、前記既設制御盤から延長ケーブルを配線する。
ステップ２：前記新設制御盤の断路端子を開にして、前記既設制御盤の配線と同種の延長ケーブルを前記新設制御盤の断路端子に接続する。
ステップ３：前記新設制御盤からの延長ケーブルを前記既設制御盤に導き、ＰＴコネクタを使用し活線状態で接続する。
ステップ４：前記既設制御盤の電源をオフし、前記新設制御盤の電源をオンした後、前記断路端子を閉にして、シーケンスチェック、動作確認を行う。
ステップ５：動作確認が完了したら、前記既設制御盤のＰＴコネクタ接続箇所の内部側を切断し、低温型熱収縮チューブまたは専用の絶縁キャップを使用した恒久処理手段で前記ＰＴコネクタの恒久処理を行う。
ステップ６：前記既設制御盤を撤去し、前記新設制御盤を配線したまま移設する。
ステップ７：活線状態のまま余長ケーブルをＰＴコネクタと低温型熱収縮チューブまたは専用の絶縁キャップを使用した恒久処理手段を用いて接続する。

In order to solve the above problem, the control panel updating method of the present invention comprises an existing control panel, a control device controlled by the existing control panel, and a large number of wires connecting the existing control panel and the control device. In the system in operation, the existing control panel is replaced with a new control panel according to the following procedure.
Step 1: The new control panel having a disconnect terminal block is installed in the same electrical room space as the existing control panel, and an extension cable is wired from the existing control panel.
Step 2: Open the disconnect terminal of the new control panel and connect an extension cable of the same type as the wiring of the existing control panel to the disconnect terminal of the new control panel.
Step 3: An extension cable from the new control panel is led to the existing control panel and connected in a live state using a PT connector.
Step 4: Turn off the power to the existing control panel, turn on the power to the new control panel, close the disconnect terminal, and perform sequence check and operation check.
Step 5: When the operation confirmation is completed, the inside of the PT connector connection portion of the existing control panel is cut, and the PT connector is permanently processed by a permanent processing means using a low-temperature heat shrinkable tube or a dedicated insulating cap. .
Step 6: The existing control panel is removed, and the new control panel is moved while being wired.
Step 7: The surplus cable is connected to the PT connector and the low-temperature heat shrinkable tube or a permanent treatment means using a dedicated insulating cap while the wire is live.

本発明によれば、既設制御盤の配線と同種の延長ケーブルを使用するため、既設接続端子番号等の工事配線調査時間が大幅に削減され、既設配線の接続は変更しないため、工事配線の切り替えの為の確認テストが不要となる。また、中継盤も不要となるため、電気室の拡張が不要になり、配線も大幅に削減され、コスト、工数が大幅に削減され、スペースの制約を受けることなく、設備停止が大幅に削減され、制御盤の更新が行える。   According to the present invention, since an extension cable of the same type as the wiring of the existing control panel is used, the construction wiring investigation time such as the existing connection terminal number is greatly reduced, and the connection of the existing wiring is not changed. This eliminates the need for a confirmation test. In addition, since there is no need for a relay panel, there is no need to expand the electrical room, wiring is greatly reduced, costs and man-hours are greatly reduced, and facility outages are greatly reduced without space constraints. The control panel can be updated.

以下、本発明の実施の形態について図を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の制御盤更新方法を適用した設備の配線を示す図である。１は既設制御盤、２は新設制御盤、３は既設制御盤１と新設制御盤２を接続する時に使用するＰＴコネクタ、４は新設制御盤内に備える断路端子台にある断路端子、５は制御装置と既設制御盤間の配線、６は既設制御盤１と新設制御盤２を接続する延長ケーブルである。
なお、図１では、配線５をはじめとして全ての線を１本の線で描いているが、実際は多数の線が使われて束ねられており、その全ての線に対して以下に説明するものと同じように取り扱う。
制御盤更新の概略は以下のとおりである。
まず、新設制御盤２から延長ケーブル６を使用し、ＰＴコネクタ３により、既設制御盤に接続する。断路端子４を閉にして新設制御盤２を有効にし、動作確認が済んだら、ＰＴコネクタ３接続箇所の既設制御盤１の内部側を切断する。ＰＴコネクタ３、延長ケーブル６は撤去せずそのまま残す。
ここで、ＰＴコネクタ３は圧縮コンタクタを押し込むと絶縁被覆を押し破り導体を挟むコネクタで、ケーブルの皮ムキをすることなく接続ができる。また、絶縁プライヤを用いて作業をすれば活線状態でも接続作業ができる。また、低温型熱収縮チューブや専用の絶縁キャップを使用した恒久処理手段を用いて恒久処理を行えば、ＰＴコネクタをそのまま残すことができる。
図２は、本発明の制御盤更新方法を適用した設備の新設制御盤２の動作確認終了後の配線を示す図である。
ＰＴコネクタ３に恒久処理手段７を行い、既設制御盤を撤去する。ＰＴコネクタ３と延長ケーブル６はそのまま残す。その後、新設制御盤を設置場所に移設し、延長ケーブル６の整理を行えば良い。 FIG. 1 is a diagram showing wiring of equipment to which a control panel updating method of the present invention is applied. 1 is an existing control panel, 2 is a new control panel, 3 is a PT connector used when connecting the existing control panel 1 and the new control panel 2, 4 is a disconnect terminal in a disconnect terminal block provided in the new control panel, A wiring 6 between the control device and the existing control panel 6 is an extension cable for connecting the existing control panel 1 and the new control panel 2.
In FIG. 1, all the lines including the wiring 5 are drawn as one line, but in reality, a large number of lines are used and bundled, and all the lines will be described below. Handle it in the same way.
The outline of the control panel update is as follows.
First, the extension cable 6 is used from the new control panel 2 and is connected to the existing control panel by the PT connector 3. When the disconnection terminal 4 is closed and the new control panel 2 is validated and the operation is confirmed, the inside of the existing control panel 1 at the place where the PT connector 3 is connected is disconnected. The PT connector 3 and the extension cable 6 are left without being removed.
Here, the PT connector 3 is a connector that pushes the compression contactor to push the insulation coating and sandwich the conductor, and can be connected without damaging the cable. Further, if the work is performed using the insulating pliers, the connection work can be performed even in a live state. Further, if permanent treatment is performed using a permanent treatment means using a low-temperature heat shrinkable tube or a dedicated insulating cap, the PT connector can be left as it is.
FIG. 2 is a diagram showing the wiring after the operation confirmation of the new control panel 2 of the equipment to which the control panel update method of the present invention is applied.
Permanent processing means 7 is applied to the PT connector 3 and the existing control panel is removed. The PT connector 3 and the extension cable 6 are left as they are. Thereafter, the new control panel may be moved to the installation location and the extension cables 6 may be arranged.

図３は、本発明の制御盤更新方法の手順を示すフローチャートである。制御盤の更新は以下の手順で進められる。
ステップ１（Ｓ１）：断路端子台を備えた新設制御盤２を既設制御盤１と同一の電気室のスペースに設置し、既設制御盤１から延長ケーブル６を配線する。新設制御盤２が既設制御盤１の側近に設置可能であれば側近に設置し、もし不可であれば、できるだけ既設制御盤１の近くに設置するのが望ましい。
ステップ２（Ｓ２）：新設制御盤２の断路端子４を開にして、既設制御盤１の配線５と同種の延長ケーブル６を新設制御盤２の断路端子４に接続する。
ステップ３（Ｓ３）：新設制御盤２からの延長ケーブル６を既設制御盤１に導き、ＰＴコネクタ３を使用して活線状態で接続する。接続には絶縁プライヤを使用する。
ステップ４（Ｓ４）：設備停止期間、定期修理期間等に既設制御盤１の電源をオフし、新設制御盤２の電源をオンした後、断路端子４を閉にする。これで、新設制御盤２が有効になるので、シーケンスチェック、動作確認を行う。なお、この状態を元に戻す必要が生じ、既設制御盤１を有効にする場合は、断路端子４を開にし、新設制御盤２の電源をオフにし、既設制御盤１の電源をオンにするという逆の手順を取れば良い。
ステップ５（Ｓ５）：動作確認が完了したら、既設制御盤１のＰＴコネクタ３接続箇所の内部側を切断し、低温型熱収縮チューブまたは専用の絶縁キャップを使用した恒久処理手段７でＰＴコネクタ３の恒久処理を行う。
ステップ６（Ｓ６）：既設制御盤１を撤去し、新設制御盤２を配線したまま移設する。
ステップ７（Ｓ７）：活線状態のまま余長ケーブルをＰＴコネクタと低温型熱収縮チューブまたは専用の絶縁キャップを使用した恒久処理手段を用いて接続する。このとき、ケーブルに余長が生じないように接続し、余りは切断する。
このように、本発明によれば、既設制御盤の配線と同種の延長ケーブルを使用するため、既設接続端子番号等の工事配線調査時間が大幅に削減され、既設配線の接続は変更しないため、工事配線の切り替えの為の確認テストが不要となる。また、中継盤も不要となるため、電気室の拡張が不要になり、配線も大幅に削減され、コスト、工数が大幅に削減され、スペースの制約を受けることなく、設備停止が大幅に削減され、制御盤の更新が行えるのである。 FIG. 3 is a flowchart showing the procedure of the control panel updating method of the present invention. The control panel is updated in the following procedure.
Step 1 (S1): The new control panel 2 provided with the disconnect terminal block is installed in the same electrical room space as the existing control panel 1, and the extension cable 6 is wired from the existing control panel 1. If the new control panel 2 can be installed in the vicinity of the existing control panel 1, it should be installed in the vicinity, and if not, it is desirable to install it as close to the existing control panel 1 as possible.
Step 2 (S2): The disconnect terminal 4 of the new control panel 2 is opened, and the extension cable 6 of the same type as the wiring 5 of the existing control panel 1 is connected to the disconnect terminal 4 of the new control panel 2.
Step 3 (S3): The extension cable 6 from the newly installed control panel 2 is guided to the existing control panel 1 and connected in a live state using the PT connector 3. Insulation pliers are used for connection.
Step 4 (S4): The power of the existing control panel 1 is turned off during the equipment stoppage period, the periodic repair period, etc., and the power supply of the new control panel 2 is turned on, and then the disconnect terminal 4 is closed. Now that the new control panel 2 is valid, sequence check and operation check are performed. When it is necessary to return this state to the original state, when the existing control panel 1 is made effective, the disconnect terminal 4 is opened, the power supply of the new control panel 2 is turned off, and the power supply of the existing control panel 1 is turned on. The reverse procedure is sufficient.
Step 5 (S5): When the operation check is completed, the inner side of the PT connector 3 connection portion of the existing control panel 1 is cut, and the PT connector 3 is fixed by the permanent treatment means 7 using a low-temperature heat shrinkable tube or a dedicated insulating cap. Permanent processing is performed.
Step 6 (S6): The existing control panel 1 is removed, and the new control panel 2 is moved while being wired.
Step 7 (S7): The surplus cable is connected to the PT connector and the low-temperature heat shrinkable tube or a permanent treatment means using a dedicated insulating cap while keeping the live state. At this time, the cable is connected so that no extra length is generated, and the remainder is cut.
As described above, according to the present invention, since an extension cable of the same type as the wiring of the existing control panel is used, the construction wiring investigation time such as the existing connection terminal number is greatly reduced, and the connection of the existing wiring is not changed. A confirmation test for switching the construction wiring is not required. In addition, since there is no need for a relay panel, there is no need to expand the electrical room, wiring is greatly reduced, costs and man-hours are greatly reduced, and facility outages are greatly reduced without space constraints. The control panel can be updated.
