The transformer of American Brucknet power station, installed many 300 to have carry cent to receive switch monitor, so that wired to 345kV and 138kV cent receives switch temperature rise,undertake monitoring. The cooling characteristic below the circumstance that the purpose depends on analysing transformer to do not have circular pump. Infra-red photograph can record the temperature section plane of radiator group together.
To the transformer in transformer substation. The main part of cooling system is core and winding. The hot loss that causes by core and winding can affect transformer efficiency and life, temperature rise can increase conductor resistance and can cause insulation deterioration, cause transformer trouble.
The transformer of a lot of transformer substation all takes radiator, although pass oily natural wind cold, but also a few undertake cooling through pump and radiator. Return some branches to use water gush transformer to enrage the refrigeration of transformer in order to carry broiling day.
Infra-red camera can rise to absorb the effect that resemble for transformer, the color of the extent of metabolic —— heat that still can show temperature and color is deeper, it can offer the visual analysis of transformer heat directly.
Those who pass cold to fine wind transformer is infra-red photograph resemble can seeing: Transformer coping oil is gentle bottom oil is lukewarm.
If be assisted from transformer,a pump mogs in equipment, through infra-red photograph the temperature rise that resembles also can seeing radiator, namely, mog a pump can cause oily velocity of flow to be in 20 seconds from 605 fall 60gpm. Inside 9 minutes of limits, radiator function can be reduced 14% , in 47 minutes in, radiator efficiency will drop 50% . Meanwhile, winding temperature rises 9 ℃ , use infra-red photograph consider to mog like the technology the result of a pump is, brought about cooling power to reduce 36% .
