Specifications
The DD862 single phase meter is designed to meet the IEC62053-21,IEC62052-11.
Construction
- Meter case
- Two types of cases are available One is the insulating case of protective-class 2 and the other is the weather-proof case complying to IEC60529 and Ip54.
- Terminal block
- The terminal block is molded of Bakelite . The voltage test link can be located inside or out-side of the meter case. The maximum diameter of the terminal hole is 8.5mm.
- Driving element
- The driving element consists of a voltage element and a current element, both of which are fixed to the frame. The voltage element has a low load adjustment mechanism, and the current element has an inductive load adjustment mechanism.
- Rotor
- The rotor shaft is made of aluminum alloy with a small hole in the upper end for storing lubrication and for fitting a brass bearing The worm is turned of brass, and is acid-cleaned or nickel-plated. The worm and shaft can be detached.
- Braking element
- The magnet is made of AINiCo5 alloy and designed as U-shaped so that the effect of short-time over current upon the magnet is negligible. The full load error can be fine controlled by adjustment mechanism.
- Frame
- The frame is die-casted by high-quality Al alloy of stable property to avoid distortion. The application of static spray-painting on the surface prevents the frame from oxidation.
- Upper bearing
- The pin is made of high-quality abrasion-proof stainless steel and is embedded on the brass pin base.
- Lower bearing
- Both double jewel bearing and magnetic bearing are available.
- Register
- The DD862 meter with direct-reading cyclometer type register is available.
- The register is self-located and is mounted on the frame by one screw. Fixing with two screws is also available but needs to be manually adjusted. There are two types of gears available: brass gears and self-lubricating plastic gears.
