[0003] The oil-immersed transformer box in the prior art does not have the function of real-time monitoring of the temperature and liquid level of the cooling oil, so it is impossible to deal with oil leakage and excessive temperature of the cooling oil in time. At the same time, the existing sub-cooling type The oil-immersed transformer box uses external electricity to drive the fan, which increases the loss of energy

The invention discloses a heat dissipation and early warning device for an oil-immersed transformer box, which comprises a main body of an oil tank, a heat dissipation pipe, an oil storage tank, a solar battery panel, a solar controller, and a cooling fan. A heat dissipation pipe is welded, and the cooling oil inlet and outlet ends of the heat dissipation pipe are divided into the upper and lower ends of the oil cavity of the main body of the oil tank, and a support frame is installed on the top of the oil storage tank. The beneficial effects of the present invention are: The heat dissipation and early warning device of the electric box supplies power for the cooling fan and the early warning device through its own solar power generation device, and can store the converted electric energy in the battery, and at the same time, transfer the electric energy stored in the battery to the grid to provide electric energy for people's lives , and through the temperature sensor and liquid level sensor installed inside the oil tank, the temperature and liquid level of the cooling oil inside the oil tank can be monitored in real time to prevent oil leakage and excessive temperature, thereby avoiding damage to the transformer box.
Description
technical field [0001] The invention relates to a heat dissipation and early warning device for a transformer box, in particular to a heat dissipation and early warning device for an oil-immersed transformer box. Background technique [0002] The distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the 10(6)kV or 35kV network voltage to the 230 / 400V bus voltage used by users. This type of product is suitable for AC 50 (60) Hz, three-phase maximum rated capacity of 2500kVA (single-phase maximum rated capacity of 833kVA, generally not recommended to use single-phase transformers), and can be used indoors (outdoors) when the capacity is 315kVA and below Can be installed on a pole, the ambient temperature is not higher than 40°C, not lower than -25°C, the highest daily average temperature is 30°C, the highest annual average temperature is 20°C, the relative humi...
