Abstract
The utility model relates to a railway signal digital cable analog network device, which is characterized in that the analog network adopts 6 sections, and the network parameter is as following: when the analog network length is 0.5 km, the resistance is 11.75 (ohm), the inductance is 0.375 (m H), and the capacitance is 7.25 (n F); when the analog network length is 1 km, the resistance is 23.5 (ohm), the inductance is 0.75 (m H), and the capacitance is 14.5 (n F); when the analog network length is 2 km, the resistance is 46.7 (ohm), the inductance is 1.56 (m H) and the capacitance is 29 (n F); when the analog network length is 2*2 km, the resistance is 46.7 (ohm), the inductance is 1.56 (m H) and the capacitance is 29 (n F). The utility model can be in mixed use with the cable of different use, thereby reducing the cable price and the engineering investment.
Description
One, technical field
The utility model is applicable to rated voltage, exchanges 750V, direct current 1100V and following high-speed overload electrified sections or non-electrified railway section signal digital transmission of Information, particularly relates to railway signal digital cable artificial network device.
Two, technical field
The insulated wire cores of the SPTYW sections road signal digital cable of China's use at present adopts three-layer co-extruded, the physical foam insulation technology of international most advanced level.Aluminium sheath has good shielding properties, can be used for the main line or the forceful electric power mush area of electrified section.Its operative norm is that Q/TL095-2000 satisfies TB/T2476-93, reference standard TB1478-83.
In view of this cable adopts φ 1.0mm copper core, the mutual capacitance of star quad less (29 ± 10%PF/m), can compare with French ZCO3 type cable (homemade PZYL23-1 type mixed type cable) 30PF/m electric capacity index.But the ZCO3 cable is the compound cable structure of φ 1.0 and 1.13 two kinds of not collinear footpath heart yearns of φ, its cost height.France ZCO3 cable artificial network employing 0.5,1,2,4km be totally four joint networks, from the every 0.5km of 0～7.5km adjustment fraction at interval.
Three, summary of the invention
The utility model technical issues that need to address are: a kind of railway signal digital cable artificial network device is provided, and the cable conductor of different purposes can mix standby, reduces cable price and construction investment.
Technical solution of the present utility model is: railway signal digital cable artificial network device, described artificial network adopt 6 joints, and its network parameter sees the following form
| Sequence number | Artificial network length (km) | R (Ω) | L (mH) | C (nF) |
| 1 | 0.5 | 11.75 | 0.375 | 7.25 |
| 2 | 1 | 23.5 | 0.75 | 14.5 |
| 3 | 2 | 46.7 | 1.56 | 29 |
| 4 | 2×2 | 46.7 | 1.56 | 29 |
The utility model compared with prior art has following advantage: at China's national situation, distance is pressed the 20km consideration between railway line two stations, adopts SPTYW railway signal digital cable.Dummycable is from 0 to 10km, and every 0.5km adjusts mode at interval.Determine the pin network parameter, uniform transmission line is done accurately simulation.Cable has single φ 1.0 lines footpath, and the cable conductor of different purposes can mix standby, has reduced cable price and construction investment.Calculate and the simulation laboratory test test shows from theory, lumped parameter is accurate to the parameter of distribution simulation, and error amount is controlled at about 1% under the various conditions.
Four, description of drawings
Fig. 1 is the utility model artificial network 0.5,1,2km equivalent circuit diagram;
Fig. 2 is the utility model artificial network 2 * 2km equivalent circuit diagram.
Five, specific embodiments
The cable artificial network moves to indoor, 6 saves total complementary range 10km totally by 0.5,0.5,1,2,2,2 * 2.
For accurately simulate the parameter of distribution of STPYW type cable with pin network, network parameter is chosen as
| Sequence number | Artificial network length (km) | R (Ω) | L (mH) | C (nF) |
| 1 | 0.5 | 11.75 | 0.375 | 7.25 |
| 2 | 1 | 23.5 | 0.75 | 14.5 |
| 3 | 2 | 46.7 | 1.56 | 29 |
| 4 | 2×2 | 46.7 | 1.56 | 29 |
Claims (2)
