ルトレイに関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is applicable to nuclear power plants and all other power plants, chemical plants, and general buildings. In general, in buildings where cables are placed on cable trays for wiring, if it is necessary to replace or modify existing equipment's electric wires and cables, disconnect the entire area to be replaced in order to recover in a short period of time, and relay terminals to connect with new cables. This invention relates to a cable tray in which a box is fixed to the cable tray.

シ換えていた。This could be a nuclear power plant or a chemical plant, but if there is a design change during construction, or if a change occurs after the start of operation and requires a partial or complete remodeling of the equipment, it may be necessary to make improvements related to the electrical system of the equipment. In the past, if it was directly related to electric wires or cables, the entire line from the source (mainly the power supply side) to the destination (mainly the load side) was replaced.
負荷と言われる機械、器具類は原子力発電プラントの例
では数千台以上にも及び、それ等にそれぞれ強弱は別に

トルのものになると床、壁、天井などを数箇所貫通して
引き回わされているのが実態で、たった一本の＠線もし
くはケーブルの取り換えのために施設全体に影響を及ぼ
すと同時にばく大な費用を費やす結果となっていた。In the example of a nuclear power plant, there are thousands of machines and appliances called loads, and power is supplied to each of them with different strengths and weaknesses, and the length of a single line varies from several meters to several thousand. There are cables up to 100 meters long. 1. Short cables are not difficult to replace, but cables of several hundred meters have to be routed through the floor, walls, ceiling, etc. in several places. In reality, replacing just one @ wire or cable affected the entire facility and resulted in a huge amount of expense.
特に床、壁、天井などの文通部のシール処理にあっては
放射能漏れを防ぐ機能を持つ特殊シールが採用されてい
るために、これを修復するに要する時間と費用は計り知
れないものがあった。In particular, special seals with the function of preventing radiation leakage are used to seal the correspondence areas such as floors, walls, and ceilings, so the time and cost required to repair them is immeasurable. there were.

ラント寿命までの間に、数限りなく発生することが予想
される。In this way, it costs a lot of money to replace just one electric wire or cable, and if the load is thousands of units or more, it requires a considerable amount of relocation of installation locations and changes in load capacity. It is expected that an infinite number of such events will occur over time.
これらの問題は随時発生し、一度に対策出来ないから、
はソ年に一度の定期点検停止時の限られた期間内で対策
していた。These problems occur from time to time and cannot be solved all at once.
Countermeasures were taken within the limited period of time when regular inspections were stopped once a year.

事を提供するにある。The purpose of the present invention is to keep the replacement of existing wiring of electric wires and cables to the minimum necessary range (1), by providing a relay terminal box on the wiring route and fixing the cable tray, and then replacing it from there. Our goal is to provide inexpensive remodeling work in a short period of time.

継端子箱を介在せしめ、該中継端子箱をケーブルトレイ
に固着させることである。Taking a nuclear power plant as an example, there are numerous devices that require electrical wiring installed inside and outside the building, and if there is a change in their installation location or capacity, the wiring and cables must be However, in the present invention, when an existing electric wire or cable is cut near the device and connected to a new electric wire or cable, a relay terminal box is interposed, and the relay terminal box is fixed to the cable tray. It is to let

で配線するようにしたものである。To explain with reference to the drawings below, in Fig. 1, a small electric motor load (not shown) was connected to the end of the cable 3 and operated in the past, but due to circumstances, its location was changed to a far away location. In this case, the relay terminal box 2 is connected to the end of the conventional cable 3, the missing new cable 4 is added and extended, and the end is protected with a conduit 5 and wired to the load end. be.
また、ケーブル６の延線上に外傷を付けたり、部分的に

子箱２を介して新しいケーブル７と取り換え復旧させる
。Further, when the cable 6 is damaged on its extension or a part of the cable 6 is severely deteriorated and needs to be replaced, it is cut off midway and replaced with a new cable 7 via the relay terminal box 2 to restore the cable.
建設当初から設置する必要のあった中継端子箱（図示せ

で大型で重量も重かったこともあって、取り付は場所は
必ず建屋の壁、柱などに設置していた。これはおのずか
ら目的も違って、入れるケーブルも出るケーブルも本数
が多く、集中管理をするための中継端子箱であった。There has always been a relay terminal box (not shown) that had to be installed from the beginning of construction, but it had a strong structure, was large, and was heavy, so it was difficult to install it in the right place. They were installed on the walls and pillars of buildings. This naturally had a different purpose; it was a relay terminal box for centralized management, with a large number of cables to enter and exit from.
本発明は一本一本のケーブルを対象に、不具合部の対策
を講する手段として考えたもので、構造も単純で軽蓋の
ため中継端子箱２はケーブルトレイＩＶｃ固着して使用
するようにした。The present invention was conceived as a means to take measures against malfunctioning parts of each cable.Since the structure is simple and the lid is light, the relay terminal box 2 can be used with the cable tray IVc fixed. did.

めて閉じる。As shown in FIGS. 2 and 3, the relay terminal box 2 is fixed by making holes for mounting bolts 2° at arbitrary positions in the cable tray 1. Open the cover 18 and insert the cable inlet 11. Insert the cable 3°6 and tighten it to the terminal block 16. New cables 4, 7 from cable outlet 12
After that, pull in the terminal block 16 and tighten it in the same way.

リワレタンなどを流し込む。The cable inlet 11 and the cable outlet 12 are sealed with, for example, epoxy resin after the cable is inserted, and then, for example, silicone rubber or two-component polyurethane is poured through the resin injection port 13.
この場合排気栓１４を開は完全に空気を抜いて湿気の入
らぬようにしてから閉止プラグ２１．２２をねじ込む。In this case, the exhaust plug 14 is opened to completely evacuate the air to prevent moisture from entering, and then the closing plug 21, 22 is screwed in.
中継端子箱２の内部に充てんの溶剤は時間がたつに従い
固形化し、弾性を有するもので容易にナイフなどで切り
開くことの出来る材料が好ましい。The solvent filled inside the relay terminal box 2 is preferably made of a material that solidifies over time, has elasticity, and can be easily cut open with a knife or the like.
それは、万一再点検を実施する場せとか配線のやり直し
があった場合に作業がしやすいからである。This is because it will be easier to do in the event that you need to perform a re-inspection or redo the wiring.
中継端子箱２はケーブルトレイ１に固着する方法の一実
施例としてポルト２０で締め付けるようにしたが、これ

とが出来る。As an example of a method of fixing the relay terminal box 2 to the cable tray 1, the port 20 is used to tighten the relay terminal box 2, but the same result can be obtained by using a clamp method or a clamp method.

出来る。In addition, if the relay terminal box 2 is installed at key points on the cable tray 1 stretched throughout the facility during new construction and wired, it can be used as auxiliary equipment for testing various equipment at the time of construction. You can also do it. This can also be expected to have the effect that when additional equipment is added in the future, which will be discussed later, it will be possible to do only partial remodeling work without having to do complete wiring work again.

ーブルの取り換えで済むので、改造工事に要する投入資
材９期間などあらゆる面で大幅に削減させることが出来
る。By using the hemp harvesting method of the present invention, only the necessary minimum number of electric wires or cables need to be replaced, so it is possible to significantly reduce all aspects of the remodeling work, including the amount of time required for inputting materials and nine months.
例えば具体的には次に挙げる事項に適用すると効果は著

（壁貫通部などのように導体表面が密閉された状態では
自然冷却が阻止されるので、抵抗構分の温度上昇がある
が、それを低く抑えるため、その部位だけ導体を太くす
る）(In a state where the conductor surface is sealed, such as in a wall penetration part, natural cooling is blocked, so there is a temperature rise corresponding to the resistance, but in order to keep it low, the conductor is made thicker in that part.)
