Set of cabinets SHPAT YUKLYa.565418.003 (SHPAT) is a part of uninterrupted power supply of devices of automation and telemechanics of train traffic.
SHPAT provides automatic switching of the first (second) feeder to the second (first) feeder (automatic reserve input) in case of voltage loss on the feeder or in case of voltage parameters exceeding the norm, input and distribution of electric power, transformation of the network voltage into the voltage required for ATDP devices (automatic and telemechanics of train traffic).
SHPAT is installed in the relay ATDP of the metro signalling, centralisation and interlocking service.
SHPAT is designed for operation in the following conditions:
- under the influence of mechanical loads and climatic factors for classification groups MS1 and K1.1 (execution UHL category 4.2 according to GOST 15150-69), respectively according to OST 32.146-2000;
- limiting air temperature at operation from plus 1 °? to plus 40 °?;
- relative humidity ...
