Detailed Product Description
DD862 single phase watt meter(wattmeter,kwh meter)
Meter case
Two types of cases are available One is the insulating case of protective-class 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 SiAl 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.
