Description
Technical field
This utility model relates to the rail return current system between rolling stock section, parking lot and main track.
Background technology
In urban track traffic DC power-supply system, the commonly used DC750V of electric power supply system for subway and
DC1500V standard, train takes stream by pantograph (or shoegear) from contact net (or conductor rail),
Traction current passes through rail return current to traction substation negative pole.Subway line is mainly by main track, rolling stock section with stop
Parking lot forms, and the contact net in rolling stock section, parking lot is by electricity segmentation and main track contact net (or conductor rail)
Connect, independent traction substation power.Main track rail leaks into the earth corrosion edge for preventing traction current
Line metallic conduit etc. takes insulation against ground to install；Rolling stock section and parking lot are mainly used in the maintenance of train, maintenance
Deng, cause personal safety to endanger staff for Handling Measures of Higher Rail Potential in preventing rolling stock section, parking lot, logical
Often the track in row inspection storehouse, carwash storehouse is connected with grounded screen or by independent grounding pole, track is straight with the earth
Connect connected.During runing, make for preventing the positive line current rail in rolling stock section, parking lot from flowing into the earth
Becoming stray electrical current leakage, the generally discrepancy section line throat in rolling stock section and parking lot arranges insulation joint and main track
Rail isolate, and in rolling stock section, parking lot away from come in and go out section line throat about 1km rail at be also provided with
Insulation joint and row inspection storehouse, the isolation of carwash storehouse.Traction substation return wire in rolling stock section, parking lot is arranged on
Between two insulation joints, for ensureing that train sets when normal reflow and train crosses insulation joint during startup in row inspection storehouse
Standby without damage, generally at the two ends parallel connection device in one-way on state of insulation joint.Device in one-way on state by organizing also more
Connection diode (only allow electric current rail in rolling stock section, parking lot flow back to main track rail) and reverse-conducting
Controllable silicon forms.
Often occurring main track Handling Measures of Higher Rail Potential during city rail normal operation, track short circuiting device forever connects
The situation on ground, or rail insulation against ground gradually destroys, thus cause main track rail to leak a large amount of stray electrical currents
To greatly.Device in one-way on state in rolling stock section, parking lot the most often simultaneously turns on, row inspection
Ground connection rail in storehouse, carwash storehouse be main track leak to the earth stray electrical current provide good backflow lead to
Road.
When train is parked in rolling stock section and parking lot, stray electrical current can flow through car body weak part and cause car body
Damage；More seriously when train is parked in insulation joint, train short circuit device in one-way on state, major part is spuious
Electric current flows back to main track rail, scaling loss vehicle arrangement by car body.In rolling stock section, parking lot, stray electrical current is serious
Time, cause the series of problems such as device housings sparking, hanging ground-wire sparking in storehouse.
Utility model content
The purpose of this utility model is to provide the rail return current system between a kind of rolling stock section, parking lot and main track
System, it can block stray electrical current and be back to the path of main track rail from rolling stock section, parking lot, reduce stray electrical
Stream is to the harm of facility in rolling stock section, parking lot.
The purpose of this utility model is realized by techniques below scheme:
Rail return current system between a kind of rolling stock section, parking lot and main track, goes out including rolling stock section, parking lot

The rail bonding device IBD2 that line AR is connected with rail SR in row inspection storehouse, carwash storehouse；Rolling stock section, parking
Between field and main track, contact net electricity segmentation DF is set；Coming in and going out, it is exhausted to arrange rail between section line AR and main track rail
Edge joint JJ1, arranges isolated rail joint JJ2 between rail in come in and go out section line AR and row inspection storehouse, carwash storehouse；It is special
Levying and be, rail bonding device IBD1 includes controlling the device DR1 full control in parallel with isolated rail joint JJ1
Type power electronic devices V1 and the primary importance sensor J1 before and after being placed in all-controlling power electronics device V1
With second position sensor J2；Rail bonding device IBD2 includes controlling device DR2 and isolated rail joint
All-controlling power electronics device V2 and diode D that JJ2 is in parallel and be placed in all-controlling power electronics device
The 3rd position sensor J3 before and after V2 and the 4th position sensor J4.
So, device IBD1 and IBD2 is separate for rail bonding, and rail bonding device IBD1 is in column free
Car by time be off state, block stray electrical current and be back to the logical of main track rail from rolling stock section, parking lot
Road, thus reduce stray electrical current to the harm of facility in rolling stock section, parking lot.Rail bonding device IBD1,
IBD2 detects when train passes through, and triggers all-controlling power electronics device conducting, it is to avoid train strides across insulation joint
Sparking problem.
When actually used, following control strategy can be taked:
J1 position sensor detects that installation position is equipped with output X=1 when train occupies, defeated when not having train to occupy
Go out X=0；J2 position sensor detects that installation position is equipped with output Y=1 when train occupies, and does not has train to occupy
Time output Y=0；The position sensor output of J3, J4 is identical with J1, J2；Position sensor J1, J2
Output train seizing signal X, Y are to the control device DR1 of rail bonding device IBD1；J3, J4 export
Train seizing signal X, Y are to the control device DR2 of rail bonding device IBD2；As X+Y > 0 time,
Representative has train to pass through isolated rail joint, controls device DR1, DR2 and exports all-controlling power electronics device
Continuity signal；As X+Y=0, control device DR1, DR2 output all-controlling power electronics device and turn off
Signal.
This utility model compared with prior art provides the benefit that:
One, this utility model can block stray electrical current rail in rolling stock section, parking lot and flow back to main track rail
Current return circuit, reduces stray electrical current to the harm of facility in rolling stock section, parking lot.
