Application:
Type DD706 and DD706a single phase long life kilowatt-hour meter is a kind of induction type meter which measure active energy and reactive energy electric power consumption in rated frequency 50HZ and single phase AC electricity netting. The type single phase kilowatt-hour meter is a new-style induction type meter which is designed and developed on the basis of type DD706 DD706a single phase kilowatt-hour meter and absorb domestic and overseas induction meter new techniques and use long life technique. It’s 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 lubricate graphite bush and stainless steel needle. It has following features: Small abrasion, long life, and small error change. All kind of adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn’t to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by user.
