Application Type DEM071 single phase long life watt-hour meter is a kind of induction type meter which measure active energy electric power consumption in rated frequency 50Hz and single phase AC electricity net. The type single phase watt-hour meter is a new-style induction type meter which is designed and developed on the basis of type DD155 single phase watt-hour meter and absorb domestic and overseas induction meter new techniques and use long life techniques. Its technique performance is completely conform to the stipulated requirement of National Standard GB/T15283-94 and International Standard IEC60521. Structure and features The meter frame adopt top-quality steel plate once molding, voltage elements adopt whole closed vacuum mounding with excellent mechanical strength, stable structure and anti-impact. The type meter adopt magnetic thrust bottom bearing; oriented bearing is made of lubricative graphite bush and stainless steel needle. It has following features: Small abrasion, long life, and small error change. All kinds of adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping neednt to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by user.
