本発明は、電線に付着した雪を効果的に融かす
融雪スリーブの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a snow melting sleeve that effectively melts snow adhering to electric wires.

いる。しかし、この低キユーリー点材２は高価で
ある上磁束密度が小さく、動作範囲が比較的広い
ため、融雪スリーブとしては比較的発熱量が少な
いという問題があつた。 As shown in Figure 1, a low Curie point material 2 is fitted into a ferromagnetic material 1' such as steel, and the low Curie point material 2 becomes magnetized at low temperatures, which creates a switching effect and can be used to connect overhead power lines, etc. A snow melting sleeve 10' is known, which generates heat due to magnetic hysteresis loss or eddy current loss and melts snow that has adhered to it when the snow melting sleeve 10' is applied to an AC power line. However, this low Curie point material 2 is expensive, has a low magnetic flux density, and has a relatively wide operating range, so it has the problem that it generates relatively little heat as a snow melting sleeve.
本発明はかかる従来技術の欠点を解消し、安価

するものである。 The present invention aims to eliminate the drawbacks of the prior art and provide a snow melting sleeve that uses inexpensive materials as a switching element and can secure a large amount of heat.

ブ１０とする。 Examples will be described below with reference to the drawings.
A pipe 1 made of a ferromagnetic material such as mild steel and having a diameter such that it can be well attached to the electric wire W as shown in Fig. 4.
As shown in FIG. 2, vertically divided bodies 1a, 1b
(Although the example shows the case of two parts, it is not meant to be limited to this). For example, they are joined using screws 4, 4, etc. to form the snow melting sleeve 10.
第３図は第２図の側面図を示したものである。
融雪スリーブ１０は第４図の如く電線Ｗに着合さ
れるのであるが、この着合は、このようにする。 FIG. 3 shows a side view of FIG. 2.
The snow melting sleeve 10 is attached to the electric wire W as shown in FIG. 4, and this attachment is carried out in this manner.

のである。 First, remove the screws 4, 4......, attach the half bodies 1a, 1b to the electric wire W, and then connect the connecting piece 3.
Place and tighten with screws 4, 4, ………………. In this case, a sealant made of a compound such as silicone rubber is interposed between the snow melting sleeve 10 and the electric wire W, partly to prevent the snow melting sleeve 10 from moving after the snow melting sleeve 10 is attached, and partly to prevent corrosion. It is better. Next, the operation of the snow melting sleeve 10 according to the present invention will be explained. Connection piece 3 is half body 1
Since the coefficient of linear expansion is larger than that of a and 1b, the gap between the joints of the half bodies 1a and 1b acts to separate them at high temperatures, and the pipe 1 does not generate heat. However, when the temperature decreases, the connection piece 3 contracts significantly, so that the halves 1a and 1b are strongly joined together.
Then, the pipe 1 is integrated, and the hysteresis loss or eddy current loss occurs and heat is generated.
この場合の接続片としては、アルミニウムなど
金属に代えて、プラスチツクの如き有機質の板を
使用することも可能である。 In this case, as the connection piece, it is also possible to use an organic plate such as plastic instead of metal such as aluminum.
