Model Meaning<\/b><\/strong><\/h2>\n

\"\"<\/p>\n

Scope Of Application<\/b><\/strong><\/h2>\n

S \u25a1 -50-4000\/35 oil-immersed transformer is suitable for AC 50Hz, rated working voltage 35kV power system, as a small and medium-sized substation transformer equipment.<\/p>\n

I<\/b><\/strong>ron Core<\/b><\/strong><\/h2>\n

The core is cold rolled silicon steel sheet with high permeability magnetic grain orientation. The iron core is a conventional iron core,an all-oblique joint stacking type iron core, the iron core column is a multi-step circular cross-section, and the iron yoke and the iron\u00a0core are equal\u00a0cross-section.<\/p>\n

Winding<\/b><\/strong><\/h2>\n

The windings are concentric coils; The high voltage winding has a tap required for the tapping voltage, which is led to the tap-changer. The switch is installed on the box cover, and the tapping voltage can be changed only after the power supply is cut off.<\/p>\n

Safety Protection Device<\/b><\/strong><\/h2>\n

The transformer is equipped with a gas relay and a pressure relief valve.<\/p>\n

Oil Protection Device<\/b><\/strong><\/h2>\n

The transformers are all equipped with oil conservators, and one end is equipped with an oil level gauge;A moisture absorber with oil seal should be installed on the transformer oil conservator;<\/p>\n

Oil Temperature Measuring Device<\/b><\/strong><\/h2>\n

The transformers are all equipped with a glass thermometer tube holder. The tube holder is located on the top of the oil\u00a0tank and\u00a0extends into the oil by 120\u00b110m;<\/p>\n

Transformers of 10000kVA and above are equipped with outdoor signal thermometers;<\/p>\n
