Application |
Model
DEM261PI inserting type three phase three
wire electromechanical reactive energy meter
is a kind of new style three phase three
wire reactive 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 2 or class 3 three
phase reactive energy meter stipulated in
international standard IEC 60145. It can
accurate and directly measure 50Hz or 60Hz
reactive energy consumption from three phase
three 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 X 234mm, 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 PA)
¡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 PM).
¡ñ Standard
configuration without the device which can
prevent retrograde, may select add the
function of prevent retrograde. (Please
specified when ordering).
¡ñ Two components
measure three phase three wire reactive
energy. The accuracy class 2 or class 3 may
select by users. Complying with standard IEC
60145. (Please specified when ordering).
¡ñ Standard
configuration use CT, type 5Z wiring for
operation, may select PT & CT (Product
Configuration code is PJ), type 5Z wiring
for operation.
¡ñ Short terminals
cover. |
