Description
Technical field
The invention belongs to power cable field of engineering technology, especially a kind of to be convenient for electric compartment inner cable circuit reversing of position
Laying method.
Background technology
Since underground pipe gallery electric compartment is the component part of entire pipe gallery, the height of piping lane, width by
System and adjacent other nacelles so that construction form, section scale and the inlet-outlet line scheme of electric compartment are different from conventional electricity
Cable ditch or cable tunnel.The especially inlet-outlet line form of cable, due to being stopped by adjacent cabin, the inlet-outlet line of electric compartment is general
Using top or cabling in the raised floor, then again to the left and right sides across（It is drill-through）Other cabins are laid to the both sides of pipe gallery.
For example, the patent document of Authorization Notice No. CN105226574B provides a kind of cable laying method comprising such as
Lower step：Laying machine installation steps：According to default laying scheme, cable layer, predeterminated position packet are installed on predeterminated position
Spaced several mounting bases are included, a cable layer is correspondingly arranged in each mounting base；Dragger installation steps：According to electricity
The distribution link of cable laying machine is set respectively in the medium position of distribution link and the end position far from First cable layer
Set cable drawing machine；Control cabinet installation steps：Neighbouring each mounting base is correspondingly arranged control cabinet, and control cabinet is electromechanical with cable laying
Property connection, the start and stop for controlling cable layer；Rate-determining steps：Each control cabinet is respectively connect with master controller, master control
Device is provided with control program, and the laying speed that cable layer is arranged is more than the hauling speed of dragger；Publication number
The branch when patent document of CN106921142A provides a kind of pipe gallery electric power cabin circuit sinusoidal laying straight line arranged in parallel
Frame method for arranging, high-tension line are laid in by holder trailing arm in the bracket upright post in electric power cabin, and high-tension line uses vertically just
String shape is laid with, and three high-tension line sections are in line arranged in parallel, and every high-tension line is single-core cable, and pulling force limits first
Value analysis, determines the permission minimum value of circuit sinusoidal amplitude；Then induced voltage is analyzed, and determines permitting for circuit sinusoidal amplitude
Perhaps maximum value；Finally determine the half of the width of the holder trailing arm and spacing, that is, circuit sinusoidal wavelength of bracket upright post.
The present invention proposes to determine pipe gallery electric power cabin circuit under the premise of meeting the mechanical property of circuit and ensuring personal safety
Bracket upright post interval, holder trailing arm width when sinusoidal laying straight line arranged in parallel, are the holder in pipe gallery electric power cabin
Design provides reference.
Either above-mentioned horizontal laying or sinusoidal laying, have the following problems：（1）Due to electric compartment scale compared with
Greatly, the cable run feeder number of laying is more, and is placed for layering, is not close to import and export when needing the cable loop of outlet
Position place when, it is necessary to pass through other cable loops, previous way be occupy electric compartment in maintenance make an inspection tour channel around
Other cables are crossed to outlet port, not only plug access path；（2）Since cable is vacantly to detour, centre lacks necessary
It is fixed, cause the practical turning radius of cable to be unable to control, and then cause inherent injury layer by layer to cable insulation, previous laying
Method blocks access path and causes serious hindrance, cable insulation damage then tight to the operation, maintenance and accident maintenance of electric compartment
The operational safety of cable run is injured again.
Invention content
In view of this, in view of the deficiencies of the prior art, it is an object of the present invention to provide one kind being convenient for electric compartment inner cable line
