Additional InformationFor use in direct current boards of thermal power plants
-
- All fused circuit breakers with fuse monitoring to provide local light and remote fuse blow alarm function.
- Continuous automatic control is provided behind the control chains:
– voltage level on bus sections;
– battery charge (discharge) current;
– level of voltage pulsations on bus sections;
– insulation resistance of the direct current network with the feeder localization function with a reduced value of the insulation resistance. The value of the threshold for triggering the alarm and localization of the feeder with damaged insulation is 20 kΩ. (ohms)
- The possibility of visual control of voltage, current, insulation resistance is provided.
- Remote signaling to the block control switchboard (the BCS1) and the central control switchboard the (CCS)
- Two-way service cabinet with lockable doors.
- A set of spare fuses in the amount of 50% of those installed in the control unit.
- Debugging control and measuring devices and debugging protocols.
- Automatic backup power supply activation of the insulation resistance control system
