Research Of Expand Function And Application Of AC Contactor

AC contactor is a kind of electrical controller that is used for connecting andseparating electric circuit. Its have characteristics of big controlling capacity, rapidaction, operating security and convenient. Its also have protecting function of lackingvoltage and widely applied in manufacturing of industry and agriculture. In pace withmodern science and technology and elevation level of automation, as the significantparts, the ac contractor is faced reform. The outdated ac contractor has a large bulk,high energy dissipation and single function. Researching of a kind of AC contractorthat have small bulk, low energy dissipation, numerous auxiliary, high level of mould,intellectualized contractors is imperatived under the situation, AC contractor is a kindof product that consuming, electricity. Along with pushing dictate work of economizeenergy sources, popularizing of contractor products with saving energy haveimportant significance. Technologies of saving energy, extending function, intelligentproducts are researched in this text. Extending function involves switch electric powercapacity, mechanical mutual lock and prolong time lock. Analyzed saving energypercentage and significance of adding different function module.
