Description
Technical field
This utility model relates to electric railway, mono-for electric railway 27.5kV particularly to one
The on-line monitoring type sheath protector that core cable grounding is installed.
Background technology
Along with developing rapidly of China's electric railway, tractive power supply system uses 27.5Kv in a large number
Special single-core cable.For ensureing that the operation of electric railway special 27.5Kv single-core cable is stable and pacifies
Entirely, the application of sheath protector is more and more extensive.On-line monitoring type sheath protector is compared to typically protecting
Layer protector has the discharge time intuitively observing cable overvoltage, special for electric railway
The operation maintenance of 27.5Kv single-core cable, and cable fault investigation provide convenience, decrease therefore
The barrier investigation time, the advantages such as operation maintenance cost are saved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of traction power supply Special single-core cable
Earthy on-line monitoring type sheath protector, to improve the maintenance of traction power supply 27.5Kv single-core cable
Efficiency, reduces traction power supply 27.5Kv single-core cable maintenance cost.
It is as follows that this utility model solves the technical scheme that its technical problem used:
Traction power supply Special single-core cable grounding of the present utility model with online monitor-type sheath protector,
Including sheath protector and on-line monitoring device, it is characterized in that: first section of connection of described sheath protector is led
Drawing power supply Special single-core armature of cable layer, end connects online monitor, and by on-line monitoring device
Outlet termination cause ground connection.
The beneficial effects of the utility model are, rational in infrastructure, take full advantage of the spy of on-line monitoring device
Point, conveniently runs, observes when safeguarding the situation of cable overvoltage, decrease the fault rate that cable uses,
Reduce the cable fault investigation time, saved cable maintenance cost, can be widely applied to electric railway
In construction.
