Roof snow-melting system of transformer substation

Abstract

The invention relates to a roof snow-melting system of a transformer substation. The roof snow-melting system comprises a transformer, a snow-melting oil pipe and a second oil pipe, wherein the transformer is provided with a heat sink and an expansion tank, coolant oil is stored in the expansion tank, and the heat sink is provided with heat sink oil ducts; the expansion tank, the heat sink oil ducts and the snow-melting oil pipe are connected in series to form a first loop, and an extending route of the snow-melting oil pipe passes through the roof of a transformer substation building; and the second oil pipe connects the expansion tank with the heat sink oil ducts in series to form a second loop, and a pump and a valve are arranged on the second loop. According to the roof snow-melting system of the transformer substation, the coolant oil of the transformer is transferred to a building roof with accumulated snow by utilizing pipelines, the accumulated snow is melted by heat released by the coolant oil, moreover, the coolant oil is cooled, and then backflows to the transformer, and a loop is formed. The system recycles the dissipated heat of the transformer to melt the snow, the energy resources can be saved, two birds are killed by one stone, heavy physical labor of workers are not needed, the snow-melting operation is safer, and automatic snow melting through monitoring the thickness of the accumulated snow can also be achieved in a preferred mode.

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.
