った。The cables are laid in a spiral or wave pattern and are connected in parallel to the MI cable 2 via a terminal block 4. For cable type electric heaters, heat transfer efficiency to process piping, outer diameter of heating element such as nichrome wire, etc.
They are cut into pieces of several tens of meters to prevent wire breakage due to high-temperature deterioration of the heating element and the required amount of heat for process piping. In this construction method, after installing the electric heater 1, a heat insulating material is installed to keep the pipes warm, the MI cable 2 is installed outside of the heat insulating material, and the outside is further protected to protect the heat insulating material and the MI cable 2. Install the cover. Therefore, the construction period for electrical work and plumbing work is divided into two parts, which has the disadvantage of requiring a long construction period.
本発明の目的は、上記欠点を解決した電気ヒータを提供
することにある。An object of the present invention is to provide an electric heater that solves the above-mentioned drawbacks.

法を第５図に示す・
電気ヒータ１はプロセス配管３の外周に直状。In Figure 4, a heating element IA made of nichrome wire and a two-core conductor 2D for power supply are arranged and housed in a stainless steel tube IC at the apex of a triangle, and filled with an inorganic insulator IB such as magnesium oxide to prevent heat generation. A cable-type electric heater 1, which is characterized by the ability to supply electricity, is provided, and its construction method is shown in FIG.

is interrupted. After installing the electric heater 1, a heat insulating material 6 and a protective cover 7 are installed.
電気ヒータ１は必要熱量に合せて数十ｍ単位に切断され
、その電気的接続は第７図のように施工する必要がある
。The electric heater 1 is cut into pieces of several tens of meters according to the required amount of heat, and the electrical connections must be made as shown in FIG.
そのため、端子箱４は端子４Ａを六個備え、Ｌ形の補助
接続片４Ｂを点対象の位置に接続しておく。Therefore, the terminal box 4 includes six terminals 4A, and L-shaped auxiliary connection pieces 4B are connected at point-symmetric positions.
電気ヒータ１の端末は発熱体ＩＡを中央部端子Ｈ１，Ｈ
２へ、三芯の導体２Ｄは左右の端子Ｒ１゜（３）
Ｒ２及びＴＩ、Ｔ２へ各々接続する。The terminals of the electric heater 1 connect the heating element IA to the central terminals H1 and H.
2, the three-core conductor 2D is connected to the left and right terminals R1° (3) R2, TI, and T2, respectively.
尚、電気ヒータの形状は第８図のように偏平とし、中央
部に発熱体ＩＡ、左右に導体２Ｄを配置すると、配管へ
の熱効率が改善され、布設作業が容易となる。In addition, if the shape of the electric heater is made flat as shown in FIG. 8, and the heating element IA is placed in the center and the conductors 2D are placed on the left and right sides, the heat efficiency to the pipes will be improved and the installation work will be facilitated.
本発明によれば、二分した施工工期を必要とせず、短期
施工が可能となり、端子箱を採用することにより誤配線
がなく容易に接続出来る利点がある。According to the present invention, construction can be carried out in a short period of time without requiring a two-part construction period, and by employing a terminal box, there is an advantage that wiring can be easily connected without erroneous wiring.
