NEWS & NOTICE

Leakage Prevention Measures For Oil-Filled Transformers

2021-07-03

When inspecting and repairing transformers and dealing with leakage, seals with good high temperature resistance and oil resistance should be selected. The most commonly used sealing material in the domestic transformer industry is nitrile rubber.

Causes Of Oil Leakage In Oil-Filled Transformers

2021-07-03

Transformers have many welding spots and long welding seams, while oil-immersed transformers are a collection of various welding and connections based on steel plate welded shells. A 31500kVA transformer has a total of more than 70 welding joints, and the total length of the welding seam is about 20m, so there may be many leakage channels.

Trial Production Of Amorphous Alloy Transformers Verifies Its Energy-Saving And Consumption-Reducing Effects

2021-06-19

At present, most of the transformers used in distribution substations are silicon steel sheet iron core transformers (SST), which are connected between the power systems, and the iron loss (no-load loss) caused by the excitation of the transformer core, that is, standby power often occurs.

The Specific Meaning Of Transformer Parameters

2021-06-08

Rated capacity Se: refers to the capacity that the transformer can deliver under the rated voltage and rated current specified on the nameplate when it leaves the factory, in kVA. The calculation formula is: Three-phase transformer Se=1.732UeIe Single-phase transformer Se=UeIe
