S22 oil-immersed power transformer is a common electrical equipment, which is mainly used for power supply voltage conversion in power systems. In the power system, because different equipment has different requirements for working voltage, it is necessary to convert the 10kV high-voltage energy entering the transformer into the working voltage integrated into the low-voltage load, which can meet the power demand of different machines. The S22 oil-immersed power transformer has a variety of features and advantages, so it has been widely used in the power system.

Structure type

●Iron core

The core is a cold-bound ferrite core with a high magnetically absorbing grain orientation. The core is a core core, and the core is stacked at the full miter joint, and the core column is a circular cross-section of a multi-level step, and the yoke and the core are equal cross-sections.

●绕阻止

The main oil channel of corrugated paper is selected for winding, and the processing technology of non-dripping paint is used to tighten the belt and bundle. The winding resistance is a same-boat solenoid coil, and the high-voltage winding has a tap that matches the tap-to-tap working voltage standard, which is connected to the tap-changer, and the switch is installed on the cover, and the tap-to-switch working voltage can be converted only after the power supply is turned off.

● Safety guards

30~2000kVA transformer is equipped with pressure relief valve;

Gas relays with alarm and trip terminals can be installed according to user needs;

●Temperature detection device

The transformers are equipped with glass thermometer sockets, which are built at the top of the oil tank and extend into the oil 120±10mm;

1000~2000kVA transformer equipped with outdoor data signal temperature gauge;

● Transformer oil tank

The transformer oil tank is composed of corrugated walls, and the interior is painted with smoke and dust, and the paint layer is solid. The corrugated radiator not only has a cooling effect, but also has an “air absorption” effect, and the corrugated radiator toughness can compensate for the change in the weight of the transformer oil caused by the ambient temperature regulation. Therefore, the sealed transformer does not have an oil conservator, which reduces the overall relative height of the transformer; The transformer adopts vacuum lubrication processing technology in the packaging form, which completely removes the moisture in the transformer, and the transformer oil is not in contact with the air. It is very likely that the transformer oil will deteriorate due to the continuous decline of water and oxygen from entering the transformer, so there is no need to carry out regular oil sample experiments.

Scope of application

●Average altitude: not more than 1000m;

●Operating temperature: -40°C~+40°C;
