摘要:

A successful circuitbreaker needs not only a suitable interrupter design but also a suitable medium in which to form and quench the arc. SF6is increasingly being used in circuitbreakers as an alternative to oil and air. This first part of a two-part tutorial looks at the implications on switching technology of SF6use; the second, in a future issue, will look at the implications for the switching system as a whole

摘要:

Industrial drying is big business and consumes much energy. Using the right process can result in more than halving the production costs for a particular part of the factory line, and maybe improve the product as well
