Description
The BPK block is intended for a power supply and preliminary coding of a rail chain since the end feeding it, the BRK — block for a power supply of two-element relays and preliminary coding of a rail chain since the end feeding it.
All three types of blocks are applied in stantsionkny rail chains on sites of the railroads with electric draft on a direct current.
Structure of a symbol
BPKR-HZ:
B — the block; П - power supply; To — codings; R — relay;
HZ — a climatic modification (At, T) and category of placement in accordance with GOST 15150-69 and GOST 15543.1-89.
Operating conditions:
- Height above sea level: no more than 1000 m
- Ambient temperature: °C-40 … +40
- Relative air humidity at a temperature: 20 °C,
- Circumambient: Inexplosive, not containing, aggressive gases and vapors in the concentration destroying metal and isolation, not saturated with water vapors and conducting dust, lack of direct influence of solar radiation
- Requirements of fire safety: GOST 12.1.004-91
- Requirements of safety measures of GOST 12.2.007.2-75
The normative and technical document on the block for interstate and export deliveries: TU 16-517.891-75
SPECIFICATIONS
Specifications of blocks, transformers and throttles of blocks are provided in table.
A power supply and preliminary coding of rail chains, and also connection to them of two-element relays of the DSR-12 and DSSh-14 types are carried out by the corresponding blocks. A power supply of rail chains is carried out by a voltage of 220 V with a frequency of current of 25 Hz, and for coding - from a network a voltage of 220 V with a frequency of current of 50 Hz.
Service life of blocks before write-off not less than 20 years.
