DD701 type long-life technology single-phase energy meter

The voltage and current iron cores formed by automatic stacking and riveting of high-speed punching machines ensure the consistency and stability of magnetic performance. The current coil and terminal are connected by brazing technology, and the worm and shaft are integrated to ensure the reliability of the electric energy meter structure and accurate measurement

Adopting imported multi-element composite material graphite bearings, treated with a unique surface diffusion process, the friction coefficient with the guide needle is effectively reduced, making its self-lubricating and wear-resistant characteristics more prominent, reducing the lateral pressure on the turntable during rotation, and ensuring the service life of the watch

High quality thermosetting engineering plastic phenolic resin injection molded integrated base, matched with polycarbonate fully transparent cover, makes the product have good sealing performance, high protection level, and radiation resistance. Long term operation is safe and reliable

The three adjustment points of full load, force rate, and light load have little mutual influence, and users can easily adjust the instrument according to their needs

Damping magnetic steel adopts high stability aluminum nickel cobalt 37 or above bipolar materials, and special temperature compensation materials are added. Its assembly is formed by one-time casting and pressing of aluminum alloy, with a reasonable structure and advanced technology

The material used for the current iron core is specially ordered, with high initial magnetic permeability, good consistency, and a straight load characteristic curve
