Description
Technical field
The present invention relates to a kind of secondary cable laying apparatu and lay technique, belonging to electrical installation field.
Background technology
At present, mostly substation secondary cable laying is to adopt the mode of artificial colligation by secondary cable colligation piecemeal on cable bearer, and this kind of system of laying mainly exists following shortcoming: 1, inefficiency.Such as lay a conventional 110kV transformer station and approximately need 15 people, 4 working days lay complete, the cable laid arranges a row cable bearer every 60-80 centimetre in cable trough, each staff is responsible for 2-4 row cable bearer, each cable bearer all needs side by side lay many secondary cables, and every root secondary cable is all that conventional laying is wasted time and energy by root colligation on cable bearer.
2, require high to cable laying operating personnel, otherwise can cause laying weak effect.May be there is cable for cable laying and tie up the situations such as cable is sagging, cable intersects, cabling is chaotic between tight, support in the operating personnel lacked experience, bring very burden for later stage investigation fault.
3, cable is easily subject to outside destroy, affects equipment safety operation.The direct frame of secondary cable is on cable bearer, and cable bearer is steel angle structure, and the position that may touch cable when dragging cable or day-to-day operation easily causes cable insulation wrapper wear and tear, reduction cable useful life, easily causes potential safety hazard.
4, secondary cable is easily caused to waste.When laying, cable length is reserved not or there is variation field apparatus position, and the cable length originally laid is inadequate, and cable is tied up cannot withdraw from because of bounding wire, causes the wasting of resources.
Summary of the invention
The object of the invention is to solve in prior art exist lay efficiency low, lay in weak effect, laid processes and easily cause secondary cable crust to wear and tear and the weak point of secondary cable waste, there is provided one lay efficiency high, lay effective, the secondary cable laying apparatu of the secondary cable crust that do not wear and tear and lay technique.
