Thus, the top cover 120 and the first heat insulation plate 130 form a double-layer heat insulation structure, which is beneficial to improving the fireproof and heat insulation effects of the transformer fireproof device 100 on the oil discharge equipment 200 in the accommodating cavity 111, thereby being beneficial to improving the protection effect on key components of the oil discharge equipment 200 when a fire disaster occurs on the transformer, enabling the oil discharge equipment 200 to be normally started for oil discharge in the high-temperature oil fire environment of the fire disaster, improving the disaster relief efficiency, and further reducing the loss.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
