Phenomenon transfer type oil leakage early warning transformer

Abstract

The invention discloses a phenomenon transfer type oil leakage early warning transformer, and belongs to the field of transformers, according to the phenomenon transfer type oil leakage early warning transformer, through the arrangement of a leakage point transfer shell, when an oil leakage phenomenon occurs on the side face of a heat dissipation fin, leaked transformer oil gradually spreads and diffuses towards the direction of an external display ball under the guidance of a liquid guide layer; compared with the prior art, the leakage point transfer shell has the advantages that the change at the leakage point is transferred to the outer side, the visibility after oil leakage is greatly improved, an early warning effect can be achieved for workers in time, and the leakage point transfer shell is simple in structure and convenient to use. In addition, along with the increase of the oil leakage amount, the color mixing filler in the internal display ball overflows and is mixed with the water-based filler, so that the color of a trace diffused after transfer is obviously changed, and a certain reminding effect on the oil leakage amount is also achieved while the oil leakage amount is reminded.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a phenomenon transfer type oil leakage early warning transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). Transformers generally include dry-type transformers and oil-immersed transformers. The transformer oil in oil-immersed transformers generally has two functions, one is used as a cooling medium, and the other is used as an insulating medium. The heat dissipation scales on the transformer communicate with the oil tank. Transformer oil will continue to heat up and cool down in the transformer, and will circulate in the cooling pipe and oil tank during this process. [0003] However, during the long-term use of the transformer, cracks will appear at the heat dissipation scales and cause oil leakage. On the one ha...

Problems solved by technology

[0003] However, during the long-term use of the transformer, cracks will appear at the heat dissipation scales and cause oil leakage. On the one hand, it will affect the overall purity of the transformer oil and cause it to be oxidized and deteriorated. On the other hand, it will reduce the content of transformer oil in the transformer and cause cooling. The effect of heat dissipation and insulation becomes worse, and there is a large potential safety hazard. However, due to the dense distribution of heat dissipation pipes on the surface of the transformer, it is difficult for the staff to find out in time when oil leakage occurs on the outer wall of the heat dissipation scales close to each other.
