なる欠点があつた。 In recent years, in order to secure substation personnel and improve the efficiency of substation maintenance and management, unmanned measures have been steadily advanced at small and medium-sized substations, regardless of whether they are in urban areas or mountainous areas, and the number of substations has also been reduced. In order to reduce energy consumption, shorten the construction period, and reduce costs, metal-clad distribution towers consisting of oil-immersed transformers and cubicles have been installed, and these distribution towers can be maintained and managed by remote control from a command center. By doing so, we aim to make it unmanned. However, in the above distribution towers installed in snowy and cold regions, it is necessary to periodically remove snow from the roofs of the distribution towers in order to protect the distribution towers from snow damage. However, in reality, snow removal work at distribution towers has been extremely difficult due to a lack of personnel for snow removal, or because the distribution towers themselves are often installed in areas with deep snow. For this reason, for distribution towers installed in areas with heavy snowfall,
To protect distribution towers from snow damage, either the distribution tower buildings themselves were constructed strongly to withstand the weight of snow, or electric heating devices (e.g. surface heating elements) were installed on the entire roof of the distribution tower. . However, the former method requires a lot of construction materials, which makes construction time-consuming and increases construction costs, while the latter method is very uneconomical because it requires electricity to melt the snow on the roof. In addition, as a result of using an electric heating device, the construction cost of the distribution tower is high, similar to the former case.

る。 Next, to explain the operation, in winter, first, the electric valve E 1 installed in the vertical oil pipe 10
Close the oil pipe 8 and upper circulation oil pipe 19.
Open the electric valve E 3 interposed between the The opening and closing operations of these electric valves E 1 and E 3 are performed manually at the onset of winter. When the oil-immersed transformer 4 is operated in this state, the insulating oil in the oil-immersed transformer 4 is heated by the heat generated during the operation of the transformer. Therefore, the heated insulating oil rises inside the oil-immersed transformer 4, and as shown by the solid line in FIG. The heat radiator 18 flows into the heat radiator 18 through the roof 3, which is in direct contact with the outside air and the heat radiator 18 is closely attached.
The heat of the insulating oil is radiated from the eaves 3a and the insulating oil is cooled to some extent, and then the insulating oil is
From the lower side inside the heat radiator 18, the oil guide pipe 20' - the lower circulation oil guide pipe 19' - the branch pipe 12 - the connecting pipe 16 - the upper common oil pipe 15 - the upper guide pipe 14 - the radiator 13 -
The oil flows into the oil-immersed transformer 4 through the lower guide pipe 14', the lower common oil pipe 15', and the circulation pipe 21, and then repeats the natural circulation along the route described above using the heat generated within the transformer. . In this way, the oil-immersed transformer 4
The insulating oil heated by the heat generated during operation is transferred from the heat sink 18 provided at the eaves 3a of the roof 3 to the eaves 3.
By communicating with a and dissipating heat, the roof 3
The eaves 3a portion will be gradually heated.
Therefore, the snow and ice accumulated on the eaves 3 of the roof 3 are gradually melted by the heat radiated from the heated insulating oil circulating in the heat radiator 18, and water is formed on the upper surface of the eaves 3. Form a film. That is, the accumulated snow and ice on the eaves 3a, which are obstructing the sliding of roof snow, are naturally slid down by the water film and removed from the eaves 3a. As a result, the snow A on the roof 3 naturally slides down the slope of the roof 3 due to its gravitational force, falls to the ground, and is removed.

ることができる。 Next, when the insulating oil is cooled by the heat radiator 18 and the heat radiator 13 and naturally circulated in the oil-immersed transformer 4, the oil temperature in the oil-immersed transformer 4 is, for example, 60°C.
In the following cases, the electric valve attached to the connecting pipe 16
E 2 a to E 2 c are closed, and the insulating oil flowing down from the heat sink 18 is transferred from the connecting pipe 16 (the one at the left end in FIG. 3) that does not have the electric valves E 2 a to E 2 c to the third pipe. The radiator on the left side of the diagram (other radiator 13
(The insulating oil is prevented from flowing into the upper common oil conduit 15 by a closing plate 17 provided in the upper common oil conduit 15.) Since only the oil-filled transformer 4 is used to circulate the insulating oil to the oil-immersed transformer 4, the insulating oil is not cooled much. In other words, since the circulation is repeated in a relatively high temperature state, the relatively high temperature insulating oil is promoted to flow into the heat radiator 18, and it is possible to enhance the heating effect of the eaves 3a portion. Become. Furthermore, when the oil temperature in the oil-immersed transformer 4 exceeds 60°C, the electric valve E2a of the connecting pipe 16 is automatically opened by a command signal from a control device (not shown), as shown in Fig. 3. In this way, two radiators 13 can be used, and when the oil temperature exceeds 70°C, the electric valve E 2 b is also opened by a command signal, making it possible to use four radiators 13. When the temperature exceeds 80°C, the electric valve E 2 c is opened and the radiator 13 is set to be fully usable, thereby minimizing the effect of the rise in oil temperature on the oil-immersed transformer 4. However, by promoting the circulation of relatively high-temperature insulating oil in the radiator 18 and effectively removing snow from the roof, and by setting the number of radiators 13 to be used according to the oil temperature, The insulating oil itself can also be effectively cooled and the oil-immersed transformer 4 can be operated satisfactorily.

に影響を与えることはない。 When it is not winter, that is, when there is no need to remove snow from the roof 3, the electric valve E1 of the oil conduit 8 is opened, and the electric valve E3 of the vertical oil conduit 10 is closed. Moreover, each electric valve E 2 a to
The control device (not shown) of E2C is stopped until the winter season, and all of the valves are left open. These electric valves are operated during distribution tower inspections in early spring. As a result, when the insulating oil is heated during operation of the oil-immersed transformer 4, the oil conduit 8-
It flows into all the radiators 13 through the vertical oil pipe 10 - connecting pipe 11 - branch pipe 12 - connecting pipe 16 - upper common oil pipe 15 - guide pipe 14 and is well cooled, and is cooled well. Since the structure is such that the insulating oil flows back into the oil-immersed transformer 4 through the motor-driven valve As a result of being blocked by the closure of E 3 , radiator 1
3 (this radiator 13 is cooled by the outside air flowing into the housing 2 from the vent 22), and the operation of the oil-immersed transformer is not affected by a rise in oil temperature. .

上幾多の優れた効果を有するものである。 As described above, the present invention circulates the heated insulating oil in the oil-immersed transformer through the heat radiator placed at the eaves of the roof of the distribution tower, and the heat radiated from the heat radiator spreads the heat to the eaves of the roof. Removes snow from roofs by heating the roof and removing accumulated snow and ice on the eaves that prevent snow from sliding off the roof, allowing the snow to slide off naturally using its gravitational force. This is completely different from conventional methods, which involve manually removing snow from the roof or installing special electric heating equipment over the entire roof. The heat is dissipated from this radiator by circulating insulating oil, and the heat removes obstacles on the eaves and allows snow to slide off the roof naturally, removing snow from power distribution towers. This eliminates the need for manpower when removing snow, and requires special construction. Snow removal can be carried out smoothly without using special heating means. In addition, since the heat radiator for snow melting is communicated with the inside of the oil-immersed transformer and insulating oil is used as a heat medium, there is no need for a heat source such as electricity, and the cost for snow melting can be completely eliminated. . Furthermore, this proposal allows the use of multiple radiators in the required number depending on the oil temperature during snow melting, so insulating oil as a heat medium for snow melting does not interfere with the operation of oil-immersed transformers only during snow melting. Circulation is possible at a relatively high temperature that does not cause damage, which promotes the circulation of the insulating oil itself.Furthermore, the relatively high temperature insulating oil can be constantly circulated to the heat sink, making it possible to melt snow on roofs. It has many excellent practical effects, such as being able to significantly promote
