|
Application |
Model
DEM141PK inserting type three phase four
wire electromechanical active energy meter
is a kind of new style three phase four wire
active energy meter, it is on the basis of
original D86 three phase electromechanical
meter, and fully absorb new technologies
about electromechanical meter from domestic
and abroad. The meter completely accord with
relevant technical requirements of class 1
or class 2 three phase active energy meter
stipulated in international standard IEC
62053-11. It can accurate and directly
measure 50Hz or 60Hz active energy
consumption from three phase four wire AC
electricity net, it is use for inserting
installed on all kinds of panels of
switchgear and distribution box. The meter
has novel design, rational structure, and it
can display total energy consumption by drum
wheel mechanical register. It has following
features: high overload, power loss,
long-life, specious appearance, convenient
installation, etc.

Functions and
features |
¡ñ
Inserting installed, the panel opening size:
152¡Á234mm, the cover is made ABS engineering
plastics molded overall which has a
transparent glass window, the bottom of the
meter and the terminal are also made of ABS
engineering plastics molded overall. It has
following features: good weather ability,
high rigid, good insulation performance,
etc.
¡ñ
The meter frame adopt aluminum molding with
excellent mechanical strength, stable
structure and anti-impact.
¡ñ
Voltage components and current components is
used of double insulation structure, has
good electrical characteristics.
¡ñ
Standard configuration the meter adopt
double gem bearing, oriented bearing is made
of lubrication graphite bush and stainless
steel needle. It has following features:
small abrasion and minimal friction, etc.
May select magnetic thrust bearing (Product
Configuration code is PC)
¡ñ
All kinds of error adjustment mechanism
adopt no step shifting mechanism. The meter
starting and creeping needn¡¯t to be adjust
which is finished by anti-creeping hole of
disc and convenient for adjusting by users.
¡ñ
Standard configuration 6 digits display by
drum wheel mechanical register, may select 7
digits display by drum wheel mechanical
register (Product Configuration code is PO).
¡ñ
Standard configuration without the device
which can prevent retrograde, may select add
the function of prevent retrograde. (Please
specified when ordering).
¡ñ
Three components measure three phase four
wire active energy consumption. The accuracy
class 1 or class 2 may select by users.
Complying with standard IEC 62053-11.
(Please specified when ordering).
¡ñ
Standard configuration use CT, type 48Z
wiring for operation, may select PT & CT
(Product Configuration code is PL), type 48Z
wiring for operation.
¡ñ
Short terminals cover. |
