Product Introduction

This transformer can be widely used in outdoor power distribution system instead of Guigang sheet iron core transformer. This product can achieve good energy saving effect and reduce air pollution through a large number of network operation. This product is especially suitable for insufficient electric energy and load fluctuation, as well as difficult to carry out and the insulation medium is free from atmospheric pollution. Therefore, it can operate in a humid environment. It is the distribution equipment in the vast distribution network in cities and rural areas.

Executive standards

◇ GB1094.1~2-2013 Power Transformer

◇ GB1094.3-2003 GB/T1094.4-2005 GB1094.5-2008 Power Transformer

◇ GB3111-1997 Insulation coordination of high-voltage transmission and transformation equipment

◇ Technical parameters and requirements of oil-immersed amorphous alloy iron-core distribution transformer (JB/T10318-2002)

◇ Q/SIHG1-1999 SBH15-M amorphous alloy iron-core sealed three-phase oil-immersed distribution transformer

◇ International standard IEC76

Structural features

◇ The transformer core is rolled with amorphous alloy strip, and the no-load loss is about 75% lower than that of S9 transformer.

◇ Copper foil coil is adopted for low voltage to improve the ability of transformer to withstand short circuit.

◇ The transformer connection group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve the power supply quality.

◇ Vacuum oil injection can eliminate bubbles in the coil and ensure stable insulation performance.

Service conditions

◇ The altitude shall not exceed 1000 meters.

◇ Ambient medium temperature shall not be higher than+40 ℃: monthly average high temperature+30 ℃; Annual average high temperature+20 ℃, low temperature: - 25 ℃.

◇ Outdoor or indoor.

◇ According to the user's requirements, transformers can be provided to operate under service conditions.
