Explosion-proof motor control stations of УВПМ type

Explosion-proof motor control stations of УВПМ type are designed for control, protection and monitoring of mining complexes asynchronous engines (rated voltage 1140/660 V) in coal mines, including hazardous of gas (methane) and coal dust. Designer and Manufacturer: PJSC “DEG”.

MAIN FUNCTIONS

The motor control station supports the following:

  • remote switching on and off of the power supplied motors by means of intrinsically safe circuits with loss of control protection;
  • remote switching on and off of the power supplied motors by means of intrinsically safe interface RS485;
  • monitoring, storage and data transfer by means of intrinsically safe interface RS485.

FUNCTIONS

The motor control station provides the following protection types and interlocks:

  • overcurrent protection;
  • motor stalling protection;
  • current overload protection;
  • phase unbalance (loss) protection;
  • preliminary insulation control of output connections;
  • control circuits short-circuit protection;
  • current protection sensors measuring circuit discontinuity protection;
  • technological time delay provision on motor start;
  • electric lock, which makes it impossible to switch off the disconnector under the current load;
  • electric lock of the power supply to the outgoing connection load with damaged insulation (lower than the permissible level).

The motor control station provides an indication of:

  • power supply voltage;
  • outgoing connection current;
  • insulation resistance of the outgoing connection;
  • values of the current protection settings;
  • protection and interlock operation.

Additional features:

  • logging of current load, protections and interlocks triggering, changes of the current protection settings to the extractable media; data transmission by means of intrinsically safe interface RS485;
  • connection of external pressure, flow rate, speed and position sensors, processing and transmission of this data by means of intrinsically safe interface RS485.
IDENTIFICATION CODE STRUCTURE

УВПМ X-XX-XXX-Y-5 – motor control station:

  • X – number of inputs (1,2,3);
  • ХХ – number of outputs(1…13);
  • ХХX – rated current, A;
  • У – climatic version according to ГОСТ 15150-69;
  • 5 – location category according to ГОСТ 15150-69.
OPERATION CONDITIONS
  • ambient temperature – from 0°C to +35°C;
  • relative humidity – up to (98 ± 2)% at the temperature of + 35 °C;
  • ambient dustiness – up to 1200 mG/m
  • operation position — slides on the horizontal plane, installation deviation in any direction from the operation position up to 15° is allowed;
  • mains voltage deviation from 85% to 110% of rated value is allowed.
CONSTRUCTION

The motor control station explosion-proof enclosure is a welded construction consisting of a central compartment, an inlet box, an outlet box, a box of intrinsically safe circuits, control and indication unit.
In the central compartment there are the main elements of the power circuit, the control and protection system, on the front side there is a handle of the disconnector that is mechanically interlocked with the “Stop” button.
Access to the central compartment is via the bolt cover on the front wall.
To the left of the central compartment there is an outlet box for connecting the power circuits of the power supplied motors, as well as control circuits.
On the right in front of the device are a control and indication unit and a box for connecting intrinsically safe circuits.
On the right in the back there is an inlet box for connecting to the power supply network and a transit input.
