Abstract

The invention discloses an energy-saving transformer top water cooling device and a control method thereof. The water cooling device comprises a top heat dissipation insulation layer, a heat insulation water tank, a cooling water inlet pipe and a cooling water outlet pipe. The top heat dissipation insulation layer is communicated with the heat insulation water tank through the cooling water inletpipe and the cooling water outlet pipe; and the heat insulation water tank is provided with a tap water inlet pipe, a domestic water pipe and a water and gas discharge pipe. The water cooling device realizes functions of water cooling heat radiation of the top portion of a transformer and storage and use of hot water. The control method realizes control the water cooling device to ensure reliableoperation through comprehensive analysis and judgment of oil temperature and oil level in a water cooling device housing and monitored data of water level, water pressure and water temperature in theheat insulation water tank. The cooling efficiency of the transformer can be greatly improved, and energy produced due to loss of the transformer itself is utilized effectively; and the top heat dissipation insulation layer can play a role of shielding solar radiation and absorbing solar energy outdoors.

Description

technical field [0001] The present application relates to the technical field of heat dissipation of transformers, in particular to an energy-saving water cooling device at the top of a transformer and a control method thereof. Background technique [0002] Power transformers are important voltage conversion and power transmission equipment in substations. In the process of voltage conversion and energy transmission, the transformer itself will consume energy and generate no-load and load losses. To put it simply, the no-load loss of the transformer is the core loss generated by establishing a magnetic field to realize voltage conversion, and the load loss of the transformer is the resistance loss of the winding wire generated by the transmission of energy. For a 110kV 50000kVA three-volume transformer, the no-load loss is about 40kW, and the load loss is about 200kW. It consumes about 5760 kWh of electricity per day at full load, and the energy consumption is huge. [000...
