Transformer Protection Often Overlooked in BCP Measures: Seismic Device for Transformers TTR
Seismic measures start with "transformers"! We achieve efficient disaster reduction measures (damage mitigation and early recovery).
The "TTR type" is a seismic device for transformers that significantly reduces the displacement of transformer terminal sections caused by large seismic motions, preventing large-scale power outages due to transformer damage. With the installation of TTR, a displacement of ±50mm or less at the terminal section has been achieved for all experimental seismic waves. Based on the building's response characteristics, it is possible to calculate and simulate the displacement of the transformer during an earthquake. In past earthquakes (such as in Eastern Japan and Kumamoto), the heaviest transformers in the cubicle were damaged, resulting in many cases where even if emergency generators were intact, electricity could not be extracted. Transformers are not readily available, meaning that operations would be suspended during that time. The TTR not only protects the transformer but also enhances the overall rigidity of the cubicle, contributing to the protection of various relays and LCBs. It enables efficient disaster reduction measures (damage mitigation and early recovery). 【Features】 ■ Significantly suppresses displacement caused by seismic motion with a special absorber at the top of the transformer ■ Effective against continuous earthquakes ■ Can be installed within the cubicle ■ Minimal changes to panel size due to TTR installation ■ Does not compromise the effectiveness of the installed vibration-damping device *For more details, please refer to the PDF document or feel free to contact us.
