| The system can monitor electric parameters such as voltage,
current, active power, reactive power, power factor, electric
quantity, on/off status of switches, and send collected data to
power management department on surface for display, store and
issue; |
| Monitoring computer of the system in power management department on
surface can modify remote alarming value or set value of action of
integrated protection devices for underground switches by online; |
| The system can collect signals such as position of switch’s
breaker, position of knife-switch, various protection actions on
regular time, and record all the events in order; |
| The system can make remote control of open/close of switch in power
management department on surface and monitoring station of
transformer station; |
| The system can make remote video monitoring of transformer stations
and devices in mine underground. The main monitoring computer can
display embedded video images, video images of alarm linkage of
personnel break-in, fire and so on, and record video images into
hard disk for enquiry; |
| When events happen such as override tripping, power failure, the
monitoring computer can send alarming sound and display in alarming
window with alarming type, status, time and so on; |
| The system can store event records, failure wave record of
integrated protection devices for switches, convenient for
engineers to analysis and determine failure; |
| The monitoring computer in power management department on surface
can make remote leak test and records for integrated protection
devices for flameproof low-voltage switches in mine underground,
and make automatic record of manual leak test; |
| The system can make assessment of electricity utilization by shifts
for teams or areas; |
| The monitoring station of the system has functions of field
plugging-in and modifying integrated protection communication
module, and can be networked with other integrated protection
devices; |
| The system has two monitoring computers, ensuring reliable running
of the system; |
| The system has remote networking interfaces such as OPC, CDT. |
