Application
Model DT833 three phase four wire electromechanical front board installed active energy meter is a kind of new style
three phase four wire active energy meter, it is on the basis of original three phase electromechanical meter, and
fully absorb new technologies about electromechanical meter from domestic and abroad, and development long-life
technology . The meter completely accord with relevant technical requirements of class 2 three phase active energy
meter stipulated in International standard IEC 62053-11. It can accurately and directly measure 50Hz or 60Hz active
energy consumption from three phase four wire AC electricity net, it is use for setting indoor or out door meter box, and
it can display total energy consumption by drum wheel mechanical counter. It has following features: High overload,
power loss, long-life, specious appearance, etc.
Structure and features
Front board three holes fixed installation, ap and down mounting holes center distance is 209 mm or 225mm, users
can choose any one by themselves.
The cover is made of PC material which is transparent and anti-UV molded overall, the base of the meter and the
terminal block is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature
molded overall. It has following features: Good weatherability, high rigid, good insulation performance, etc.
The meter frame adopt top-quality steel plate once molding with excellent mechanical strength, stable structure and
anti-impact.
Voltage components are used of all closed vacuum pouring coil by epoxy resin. Current components is used of
double insulation structure, has good electrical characteristics.
The type meter adopt magnetic thrust bottom bearing, upper oriented bearing is made of lubrication graphite bush
and stainless steel needle. It has following features: Small abrasion, long life and minimal friction, etc.
All kinds of adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn?t to be
adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by users.
Standard configuration 6 digits display by drum wheel mechanical counter, may select 7 digits display by drum wheel
mechanical counter.
Three components measurem three phase four wire active energy consumption. Complying with standard IEC 62053-
11.
Standard configuration for direct connect operation, we can also choose another type of wiring, and use CT , type
48B wiring, and PT & CT ,
Standard configuration extended terminal cover, it is for protecting use electrical safety, may select short terminal
cover.
