1. The connecting pipe is based on the principle of the connecting device. A red ball in the glass pipe indicates the oil level, which is very intuitive.

2. The pointer position of oil level gauge marked some direct Pointers indicate the fuel oil storage cabinet, or by different temperature corresponding curve (usually three, corresponding to different minimum ring temperature region: such as oil-immersed transformer oil level gage to 30 °, + 20 ° and + 40 °, respectively is refers to the oil-immersed transformer at ambient temperature was minus 30 °, + 20 ° and + 40 ° normal oil level line.) , according to the position of the pointer to convert the amount of oil in the oil storage tank.

3. For the bellows type, the top of the bellows shall indicate the normal oil level of the oil storage tank corresponding to different oil temperatures.

3 phase transformer exporter shares that according to different situations, at present, the capacity of 630kVA and below 10kV oil-immersed transformer almost has no oil storage tank, so it is unnecessary to observe the oil level. Oil storage tank is installed in 35kV and above voltage grade or 10kV oil-immersed transformer with larger capacity. The oil level indication of oil storage tank is in such several forms as connecting pipe, pointer type oil level gauge and bellows. The connecting pipe adopts the principle of the connecting device. There is a red ball in the glass pipe to indicate the oil level, which is very intuitive. Pointer type oil level gauge some directly mark the position indicated by the pointer indicates the amount of oil in the oil storage tank, or through the different temperature corresponding curve (generally three, corresponding to the lowest temperature of the region), according to the location of the pointer conversion out of the oil in the oil storage tank; The top of the bellows is used to indicate the normal oil level of the oil storage tank with different oil temperatures (generally, the oil content of the oil storage tank is about 10% of the oil weight of the body).

oil-immersed transformer

The above is the common oil-immersed transformer common oil level measurement and the main way and method of understanding for your reference, for oil-immersed transformer you have any other questions please pay attention to our manufacturers or with our technical personnel to communicate and exchange it!
