Resin dry type transformer life cycle

Life Cycle: full performance from the beginning to the body to give a complete loss of the performance of the entire process . An insulating material , an insulating structure or even to a electrical products , is not a simple body , is required to have multiple components , such as electrical, mechanical and physicochemical properties. In its lifetime , an essential element of any failures have led to the end of its life . So, end of life is sometimes manifested as natural aging type , sometimes manifested as sudden unexpected . Many factors affect the life . Naturally, the internal and external factors, external factors act by internal factors . From the composition of the structure, the life of the resin  air circuit breaker  transformers consists of life , the life of insulation , structural fasteners life electromagnetic structure of three parts. Practice has proved that the elements that play a decisive role in the life of the insulation structure. For resin insulation dry-type power transformers,  circuit breakers  except SiO2 inorganic materials , all the rest of the organic polymer materials and organic materials accounted for 40 % -60 % volume fraction of insulation . Shielding material is oxygen and water as well as in organic matter decomposition temperature of the work environment , their life is almost timeless. Therefore, the resin insulation dry-type power transformer coil insulation life depends on the structure of the resin parts. Many factors affect the life of the insulation structure . Are: the electric field distribution and strength ; role of electric power and strength ; operating temperature and the stress state ; composition structure and composition of the insulating properties of the merits of the material ; operating environment of the product. Therefore , to achieve the life of the transformer, advocates from the " embryo " to start . Transformer life given by the manufacturer , parenting by the user.

Epoxy cast transformer design and the protection of life

Reliability and service life of electrical products manufacturers and users are always issues of mutual interest , the design of electrical products rated life at different electrical applications and different times have different concepts and requirements, it should take into account the skill of the art progressive social and economic benefits of speed and overall , not too short, but not infinite . Just due to the rising level of loss or noise standards continue to improve and insulation technology makes  Air circuit breaker  transformer constantly being eliminated as a result , because they too old , although they may still use . In fact, a  electric meter  in its few years of its commissioning energy efficiency is much higher than the old scrapped a transformer consideration paid . Therefore , it should be relatively slow progress in the technology limited period of time to maximize the life of the product life design principles. Designed to protect the life and the life of electrical products is a systematic project , which involves the following six thematic areas : mechanical design and structural strength  mcb circuit breaker  ; electric field intensity electric field of design and aging ; temperature control and hot thermal insulation structure of the physical effects of aging ; nominal initial performance of the insulation structure life-giving ; wound repair , healing or regeneration projects ; protect electrical products rated operating environment. Which will affect the design or improper handling any aspect of their overall life , failure of any one link will lead to the end of life electrical products .
