DEM081 three phase watt hour meter

Application DEM081 series three phase watt-hour meter is a kind of induction type meter which measure active energy electric power consumption in rated frequency 50Hz and three phase AC electricity net. The series three phase watt-hour meter is a new-style induction type meter which is designed and developed on the basis of D86 series three phase watt-hour meter and absorb domestic and overseas induction meter new techniques and use long life techniques. Its technique performance are completely conform to the stipulated requirement of National Standard GB/T15283-94 and International Standard IEC60521.Structure and features The series 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, small error change. The meter frame adopt top-quality steel plate once molding with excellent mechanism strength, stable structure and anti-impact. All kinds of adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn抰 to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by user.
