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

\"\"<\/p>\n

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

SFZ11-1600-31500\/35 oil-immersed transformer is suitable for AC 50 Hz, rated working voltage 35 kV power system, as a small and medium-sized substation transformer equipment.<\/p>\n

Iron 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 cross-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;<\/p>\n

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 tank and extends into the oil by 120\u00b110 m;<\/p>\n

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

Transformer Oil Tank And Its Accessories<\/b><\/strong><\/h2>\n

The transformer is generally not supplied to the car, and the welding position of the bottom bracket should comply with the provisions of GB 6451;<\/p>\n

The lower wall of the oil\u00a0tank is equipped with an oil sample valve, and the lower part of the transformer oil tank is equipped with an\u00a0oil discharge valve large enough.<\/p>\n

Working Conditions<\/b><\/strong><\/h2>\n

Installation height: altitude no more than 1000 m<\/p>\n

Ambient temperature: -40\u2103\u00a0~+40\u2103<\/p>\n
