Description
One, technical field:
The present invention relates to the secondary connection link during generating set and construction of transformer substation, in particular to a kind of cable is secondary to be connect
Line layered peeling ranking method.
Two, background technique:
Secondary connection is a spotlight of the important link and substation's technique during construction of transformer substation, high efficiency
Secondary connection can effectively improve the construction speed of project middle and later periods.Voltage class of electric power system and the degree of automation at this stage
Higher and higher, the extensive use of especially Microcomputer Protection, complex automatic system keeps substation cable quantity more and more, control
Cable processed just has as many as upper myriametre, it is few then up to a hundred, more then thousands of, and have a cores up to ten thousand.If controlling manufacturing cable head not
Specification, unsightly, cable card mark is unclear for wiring technique, and fixation is irregular, not only influences technique beauty, also will affect substation
Construction quality, therefore eliminate secondary connection construction technology defect, fast and effeciently cope with various applying during secondary connection
Work is difficult, and it is vital for improving substation secondary wiring quality technological level.
Three, summary of the invention:
The technical problems to be solved by the present invention are: overcoming the deficiencies of the prior art and provide a kind of secondary cable wiring layering stripping
Skin ranking method, this method can arrange more cables in narrow space, reduce difficulty of construction, improve the efficiency of construction
And quality.
The present invention is adopted the technical scheme that in order to solve the technical problem:
A kind of secondary cable wiring layered peeling ranking method, the specific steps of which are as follows:
A, preparation of construction:
1) expendable material and construction tool needed for preparing secondary connection construction；
2) construction drawing and cable inventory are checked, specification, model are checked, checks appearance without damage phenomenon；
B, operating procedure:
1) cabling:

The crust and steel armour of cable；
B, welding steel armour ground line is wrapped up neatly in weld insulating self-adhesive band；
C, cable is fixed in screen cabinet stull and is arranged, recorded putting in order；
2) manufacturing cable head:
A, cable skin and shielded layer are stripped, the shielded layer of 3cm long is stayed to be attached with ground line；Copper woven shield ground connection；Electricity
Cable end shielding layer grounding line is wound around on end shielded layer, and uses tin welding；
B, it after end winding, puts on heat-shrink tube and carries out pyrocondensation with heater；
C, end is subjected to pencil arrangement, and height arranges unanimously；
3) cable identification board is fixed:
The end made is fixed according to the order of connection, and is hung, banded cable board；
4) wiring:
A, school line is carried out to cable, binds cable core after the line of school, binding spacing is uniform, and binding head is outwardly；
B, the core wire of cable is accessed into terminal block, arranged from top to bottom；Core wire is drawn in the sustained height of terminal block corresponding position
Out；Or part core wire is integrally drawn to (beam splitting line), wiring position is being led to, is respectively individually drawing core wire；
C, core insulation skin is stripped, length is consistent with access terminal block, and core wire sheath notch keeps smooth；
D, by wire size pipe sleeve in the position close to terminal, number font is upward；
E, the spare core wire high unity of cable, core is not exposed, and spare core is closed using plastics pullover；
F, mutual secondary circuit is flowed comprehensive from screen one point earth, presses mutual secondary circuit must reliable ground；
G, after the completion of wiring, bonding line and rigid armour ground line every 3 are got one's things ready binding and fixing with band, and access grounding copper
Row.
In the cabling step, the aligning method of cable uses double joint and one-to-one arrangement together.
The end shielding layer grounding line is process by the copper flexible cord of multiply, and section of end shielding layer grounding line
Face is 2.5mm.
The cable identification board is overlapped using front and back or is hung side by side, by the way of upper and lower high infraversion malposition；The cable
The Binding material of Sign Board is process by cable core wire material；The size of the cable identification board are as follows: diplopore 32mm × 68mm,
Mark content is followed successively by cable number, cable model, starting point, terminal.
The Wiring step middle separated time beam extraction location and harness turning are provided with binding measure, harness after binding and
Branching beam keeps smooth vertical and horizontal.
The cable core can be multiply, and the multiply core wire accesses terminal after being crimped using line nose, described
Line nose it is consistent with core wire and bolt specification.
The connecting terminal wiring is 1 or 2, and different cross section core wire must not connect on same connecting terminal.
Described to fix position consistency with row's screen case cable stripping, height is consistent after the manufacturing cable head, the wire size pipe
Length is consistent, and the cable card hanging position is consistent, and the spare core length is consistent, the core wiring cabling mode
Unanimously, the same row is consistent with screen cable arrangements mode, and the cable core crooked radian is consistent.
