Details description
Application:
DT862 series three-phase four-wire, DS862 three-phase three-wire AC kwh meter is kind of mechanism induction-type meter, This series is national unified designed product, It is measures the three-phase four-wire, three-phase three-wire AC active electric energy, Its technical norm completely accords with GB/T 15283-1994 national AC active energy meter standard, and IEC 521 international standard
Structure:
It is composed of three group electromagnet elements, two disc, damping magnet steels, aluminum - alloy frame , five or six large drum-shaped counter , terminal-block and case , The divided formation structure is used in electromagnet element , and put both side of frame , in order to improve the stability of energy meter , the voltage iron core adopts enclosed insert mode, the damping element adopts aluminum nickel cobalt magnet steel, and the hot-magnet alloy made as temperature compensation , after the move system has been balanced verified, its bearing of anti-shock spring double jewel structure to prolong the energy meter lifetime.
Characteristics:
Large load range, lifetime of 10 years and above, low power consumption, good consistency aluminium alloy frame managed by recycle so has good mechanism property. The imitation corundum put in both side of register, moving bearing, gear friction is small, high stability, reliability, easy to maintain Electric function confirm with IEC 521 international standard.
