Functions
and Characteristics |
|
 |
Have the functions of real-time monitoring
and local displaying the electric parameters of the power supply
system under 10kV, such as voltage, current, active power, reactive
power, power factor, electric quantity, on/off status of switches; |
|
Can do on/off control on the surface ground
for new flameproof power feeding switches and general mine-used
switches; |
|
Have comprehensive protection functions
of overload, short-circuit, loss of phase, electric leakage,
and insulation monitoring; |
|
Have comprehensive solution for the
voltage degrades of 660V ~ 1140V of coal mine and all power
feeding switches of manufacturers, realizing power monitoring
and control of mine wide; |
|
Equipped with video monitoring
and control device, the system can realize unmanned watch or
less men watch for the transformer station underground; |
|
With flexible structure, the system
can be switched into Model KJ95N Integrated Monitoring and Control System for Coal Mine , or switched into the Ethernet, also can
be constituted as power monitoring and control system for mine
wide by self; |
|
Have self-diagnosis functions
including check of transmission, test of error rate, statistics
of sensor fault and outstation fault, also have remote diagnosis
through Modem; |
|
Support many kinds of graph format,
and can draw various kinds of analog graph on the screen with
simple graph engine; |
|
Can create various kinds of report
form by user conveniently and print required data tables, graphes
and curves. |
