Abstract
The utility model discloses a bending device for a lead wire of a secondary cable in a substation, which is composed of a cone-shaped stick and a handle arranged at a bigger end of the cone-shaped stick. A plurality of annular grooves are arranged along the cone-shaped stick axially, and the diameters of the annular grooves arranged from a smaller end to the bigger end of the cone-shaped stick are gradually increased. The center of the portion provided with the annular grooves on the cone-shaped stick is provided with a through hole running through radially. The bending device for the lead wire of the secondary cable in the substation is simple in structure, low in manufacture cost, easy to operate, high in technology quality standard and capable of greatly improving construction efficiency and shortening construction period.
Description
Technical field
The utility model belongs to substation equipment installation apparatus technical field, relates to a kind of converting equipment control, the employed secondary cable wiring construction equipment of protection, especially relates to the curved line apparatus of a kind of substation secondary cable tail.
Background technology
Deepen continuously along with what intelligent substationization, automation construction were applied, the automatization level of converting equipment improves constantly, operation of equipment fast and safely, reliability is high.The use principle of converting equipment automation is to utilize microcomputer protective relay, control device to be communicated with the automatics of circuit breaker through armouring secondary cable lead-in wire, through realizing remote control branch, combined floodgate at background work computer transmission signals.In order to improve the reliability of branch, feed motion;, equipment transmission qualified except protective relaying device sensitivity meets the requirements; The contact place secondary circuit voltage drop of armouring secondary cable and terminal board can not exceed standard, and guarantees that the prerequisite that secondary circuit voltage drop does not exceed standard is that secondary connection technology will be according to the standard crimping, and each root secondary cable lead-in wire must be made a coil according to crimping bolt external diameter in the crimping of terminal board; Coil is enclosed within on the crimping bolt is fixed; To increase secondary cable leading-in conductor contact-making surface, improve the through-flow coefficient of secondary cable, reduce secondary circuit voltage drop.At present, in secondary cable wiring work progress, the secondary cable lead riser all is to curve crimp band with nipper pliers, because workmen's quality is uneven, the crimp band processing quality that nipper pliers curves also is uneven, and efficiency of construction is low.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides the curved line apparatus of a kind of substation secondary cable tail simple in structure, that result of use is good.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of substation secondary cable tail is bent line apparatus; It is made up of tapered rod and the handle that is arranged on the big end of tapered rod; Axially offer several annular grooves along tapered rod; Tapered rod increases to the annular groove diameter that big end offers from small end successively, and the center that offers the part of annular groove on the tapered rod is provided with the through hole that radially runs through.
Described substation secondary cable tail is bent line apparatus, and several annular grooves on its tapered rod evenly distribute along the tapered rod axial spacing.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This substation secondary cable tail is bent line apparatus, and it is simple in structure, novelty reasonable in design, and cost of manufacture is low; The crimp band shape that the secondary cable lead riser is curved is identical, easy to operate, and speed is fast; Craft quality standard is high, can improve efficiency of construction greatly, shortens the completion time of project.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode sketch map of the utility model;
Among the figure: the 1-handle; The 2-annular groove; The 3-through hole; The 4-tapered rod; 5-secondary cable lead-in wire.
Embodiment
Below through embodiment and combine accompanying drawing that the utility model is done further explain.
Like Fig. 1, shown in 2; This substation secondary cable tail is bent line apparatus; It is made up of tapered rod 4 and the handle 1 that is arranged on the big end of tapered rod; Axially offer the equally distributed annular groove 2 of several spacings along tapered rod, tapered rod increases to the annular groove diameter that big end offers from small end successively, and the center that offers the part of annular groove on the tapered rod is provided with the through hole 3 that radially runs through.
Above-mentioned tapered rod material can be adopted as smart steel, because the cross section of 35 ~ 110KV transformer station employed copper core armouring secondary cable roughly is divided into 1.5mm
2, 2.5mm
2, 4mm
2, 8mm
2, therefore, on tapered rod, go out 1.5mm with machined into according to conductor cross-section
2, 2.5mm
2, 4mm
2, 8mm
2Four annular grooves.
During use; The workmen inserts the end of a thread of secondary cable lead-in wire 5 in the through hole that radially runs through 3 on the tapered rod 4; Secondary cable lead-in wire edge and the said through hole 3 corresponding annular grooves 2 formation coil that rounds is cut excessive thread ends in the through hole again, can carry out crimping.
