Mechanical Watt-hour Meter

We are amechanical meter supplier.This productis a reliable long servicelife meter. The average service life (MTTF) is 10 years. The specifications ofthe mechanical watt-hour meter can be tailored to customer requirements.

Structure and Features of MechanicalWatt-hour Meter:
1. Meter case
Two types of the cases are available.
2. Terminal block
The terminal block is molded of Bakelite.
3. Driving element
The driving element consists of a voltage element anda current element, both of which are fixed on the steel frame of fine magneticconductivity. It has a load curve compensation device, low load and inductiveload adjustment mechanisms.
4. Rotor
The worm is an un-detachable part of the rotor shaft so that the mesh betweenthe worm and shaft is improved. Both ends of the shaft are embedded withgraphite bearing to ensure the long service life of the meter.
5. Braking element
The magnet is made of AlNiCo5 alloy and designed asU-shaped so that the effect of short time over currents upon the magnet isnegligible.
6. Frame
The frame is made of high-quality steel. Its surface is treated by negativeelectrophoresis to achieve excellent corrosion-proof.
7. Register
The register adopts heat- and abrasion-proof plastic gears and bearings. Nolubrication of bearings is needed during the service life.
