The power distribution system
DOMINO the DOMINO combined cubicle switchboard
[Brief Introduction] The DOMINO series
of combined cubicle switchboard are mainly used in the electric power
plant, each kind of factories and mines, the guesthouse and so on
as the power supply system with 50-60Hz AC, 380V fixed voltage or
660V below. And as the power distribution supply, the electric motor
control and the illumination power distribution, it may also be used
on the ships, the moving vehicles, the platform of marine petroleum,
and in the nuclear stations. |

| The series of XJM7 low voltage electrical energy measuring meter
box
[Brief Introduction]
The KWP series
of illumination electrical energy measuring meter box is suitable
for the electrical energy central measuring management which is
used in the apartment building and the office building. It may install
the pulse electrical energy meter according to the needs of design,
to realize the computer management, and it leaves the position for
the installment of telemetering and the long range communication
equipment. In the meter box the small circuit breaker is installed,
which has the function of overload and short circuit protection.
The nominal current of electrical energy meter and circuit breaker
is selected by the design.

[working
conditions]
The meter box should be installed indoors,
and ought to be able for the normal use under the following condition:
1st, surrounding air temperature
Upper limit value is +45℃, while lower limit value is -5℃. The mean
value should not surpass +35℃ in 24 hours.
2nd, the atmospheric condition
The air is clean. When the maximum temperature is +45℃, its relative
humidity should not surpass 50%, but under the lower humidity, the
large relative humidity is permitted. For example when it is +20℃,
the relative humidity is 90%, but the possibility of accidental moderate
congealing dew should be considered because of the humidity change.
3rd, the sea level of the using place should not surpass 2000M. |

[Brief Introduction]
he KWP series of low voltage electrical energy
measuring meter box is suitable for the measuring management of three-phase
four wire power and illumination. The merits are the large capacity,
the optional by-passing out switch according to the design and the
guards against electricity stealing. It is nimble, mobile, and reliable
equipment for power distribution measurement.
