The network planning of rail reflux.Electric substation passes through contact net or conductor rail to train power supply, contact net, locomotive, rail
Forming circuit makes traction current flow back to traction substation.Since the insulation resistance between rail and ballast bed structure or tunnel is not nothing
It is poor big, the cathode of traction substation cannot be all flow back into via rail when such traction current flows through rail, wherein there is one
Point traction current can be leaked on ballast bed structure and tunnel, and flow into the earth, be led to especially at rail fastening supporting point, at this
Cross rubber mat plate in fastener and Insulation rail distance keeper carry out the insulation processing of rail, but in Practical Project traction current be easy to from
It is revealed at this.The traction current leaked above rail is stray electrical current.Therefore, following lack exists in the prior art
Point: 1. rail insulation performance is poor at fastener node, only relies on railway rail pad, gage block insulation, the leakage of Yi Fasheng stray electrical current
The case where corroding periphery buried metal pipeline, communication cable crust and reinforcing bar.2. under humid environment state, rail and railway roadbed
The air insulation value in the hanging space 70mm between face can decline, and be also easy to produce stray electrical current leakage.3. fastener node surface easily quilt
The physical pollutions such as greasy dirt, dust, iron filings, fastener node are much smaller than the insulation resistance of fastener body along face bleeder resistance, so that
Insulation performance failure between rail and the earth.4. at fastening elastic rod be fastener and rail minimum creep distance, easily by dust,
The impurity pollutions such as iron filings, so as to cause the failure of insulation between rail and fastener.
Buried metal pipeline around subway does not carry out insulation package processing, the corrosion vulnerable to metro stray current.
