Application:
DD862 and DD862a single phase electric meter are induction meter. It is used in calculating 50Hz single-phase AC active electrical energy. It is composed of electromagnetic element, moving disc. Bearing, damping magnet steel, counter and regu-lator equipment etc. The meter has high precision, high over-long lifetime and so on features.
Structure characteristics
The voltage iron core adopts semienclosed inset model. The current adopts two stage compensation to have wide load property. The whole plastic-enc-losed voltage coil, can oithstand instantaneors large voltage impulse. The double jewels bearing or the magneticpropelled bear can ensure long lifetime. The bi-polar aluminium nickel cob-alt damping magnet steels have high coercivity. Stable magmetic property. The electric function is in accordance with IEC521 international standard.
