Roof snow-melting system of transformer substation

Abstract

The invention relates to a roof snow melting system of a substation, which includes a transformer, the transformer is provided with a radiator and an oil conservator, cooling oil is stored in the oil conservator, the radiator has a radiator oil channel, and also includes a snow melting oil pipe and a second oil pipe, an oil conservator, a heat dissipation The oil passage and the snow melting oil pipe are connected in series to form the first circuit, and the snow melting oil pipe extends through the roof of the substation building; the second oil pipe connects the oil conservator and the cooling oil passage in series to form the second circuit, and the circuit is provided with pumps and valves. The above-mentioned snow melting system uses pipes to transport the cooling oil of the transformer to the snow-covered roof of the building. The cooling oil releases heat to melt the snow, and realizes the cooling of the cooling oil, and then returns to the transformer to form a cycle. The system recycles and utilizes the heat dissipation of the transformer to melt snow, which can save energy and kill two birds with one stone. In addition, the staff does not need heavy physical labor, and the snow melting operation is safer. In the optimal mode, the snow thickness can be monitored to realize automatic snow melting.

Description

technical field [0001] The invention relates to substation facilities in cold regions, in particular to a system for melting snow on the roof of a substation. Background technique [0002] In some high-altitude cold regions, substations still need to be installed, and the roofs of buildings in substations often accumulate snow in winter. The increasing snow accumulation will cause the building to bear more and more loads, and when the limit is exceeded, the building structure will be damaged. On the other hand, part of the snow accumulated on the roof of the building repeatedly melts and freezes during the high and low temperature periods of the day, which will damage the roof insulation and waterproof structure, and the melted ice water will flow into the rainwater pipe. In the case of rapid cooling weather, the melted water will freeze in the pipe. It can cause the rainwater pipe to rupture. [0003] The current solution is to require substation workers to remove snow fr...

On the other hand, part of the snow accumulated on the roof of the building repeatedly melts and freezes during the high and low temperature periods of the day, which will damage the roof insulation and waterproof structure, and the melted ice water will flow into the rainwater pipe. In the case of rapid cooling weather, the melted water will freeze in the pipe. can cause rainwater pipes to burst

[0003] The current solution is to require the substation staff to go to the roof to remove snow regularly. However, due to the severe lack of oxygen in high-altitude areas, the staff cannot carry out heavy-duty operations. If it is at night in winter, the outdoor weather conditions are extremely harsh, and snow removal work is even more impossible.
