Abstract
The utility model discloses an equilateral triangle fixing support for a cable laid underground. The equilateral triangle fixing support enables a single core power cable with a voltage level of 110 kV or more than 110 kV to be arranged as an equilateral triangle. The fixing support comprises a triangular shroud ring, an upper shroud ring and a lower shroud ring, wherein the triangular shroud ring is provided with an equilateral triangle framework, three angle tips of the triangular shroud ring are all provided with tension sleeves and winged edges, and the winged edges of triangular shroud ring are connected with the winged edges of the upper shroud ring and the lower shroud ring through bolts. With the fixing support, it is guaranteed that a high voltage single core power cable is laid in the shape of an equilateral triangle, an alternating magnetic field generated by core current of the high voltage single core power cable is balanced, ring current of a metal sheath and faults caused by the ring current are reduced, and transmission capability and a service life of a cable line are improved. When the equilateral triangle fixing support is used for laying of cables, construction is convenient, repeated placing and correction are not needed, so work efficiency is improved and labor intensity of workers is mitigated.
Description
Technical field
The utility model relates to the positive triangle fixed support of a kind of cable bearer that attached cable is used in the cable trench, particularly underground laying cable, can make the single-core power cables of 110kV and above electric pressure arrange convenient construction by equilateral triangle
Background technology
110kV and above electric pressure power cable all are single-core power cables, during normal the operation. the alternating magnetic field that high voltage single-core cable core electric current produces will produce induced voltage at metallic sheath, for guaranteeing cable security stable operation and attendant's personal safety, require cable metal sheath to have at least an end reliable ground or cable metal sheath cross interconnected, can make cable metal sheath produce circulation after the ground connection.The excessive situation of circulation happens occasionally, and maximum can reach more than 90% of core electric current, and bigger circulation not only causes huge loss, also will influence conveying capacity and the service life of cable line.Along with the raising of transmission capacity and electric pressure, for reducing metallic sheath circulation, single-phase three cable laying mode consistent degrees have been proposed requirements at the higher level, wherein single-core cable equilateral triangle arrangement mode is the most obvious to reducing metallic sheath circulation for this reason.At present, in the cable trench, be to use angle bar to put cable as strut, strut pounded on the sidewall of cable trench, cable is put on it.For single-core cable is triangularly arranged, need manually put, align, frequent appearance is just put into the cable of equilateral triangle because follow-up construction makes the triangle distortion, has to ajust again.When operation, because the cable vibrations also can make cable be subjected to displacement.Therefore the engineering staff needs a kind of fixed support that single-core power cables is arranged by equilateral triangle.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provide the underground laying cable positive triangle fixed support, the single-core power cables of 110kV and above electric pressure is arranged by equilateral triangle, guarantee the conveying capacity of cable line, improve the operating efficiency of cable laying, alleviate working strength of workers.
The technical program can reach above-mentioned purpose: the positive triangle fixed support of underground laying cable comprises the triangle shroud ring, goes up shroud ring and following shroud ring, the triangle shroud ring is provided with the equilateral triangle framework, be equipped with cranse and wing limit at its three the top of the horns, Bolt Connection is passed through on the wing limit of triangle shroud ring and the wing limit of last shroud ring and following shroud ring.
Compared with prior art the beneficial effects of the utility model are:
1, can guarantee that the high pressure single-core power cables lays by the equilateral triangle mode, the alternating magnetic field balance that high voltage single-core cable core electric current is produced, reduce the circulation of metallic sheath and the fault that circulation causes, improved conveying capacity and the service life of cable line.
2, use the utility model cabling, easy construction need not to repeat to put, and proofreaies and correct repeatedly, has obviously improved operating efficiency, has alleviated working strength of workers.
3, by in side of the present utility model or end face is scribed or reference numerals numbering or apply different colors to distinguish the cable of different circuits, make things convenient for the staff to distinguish, for construction provides convenience.

Fig. 1 is front view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
Do below in conjunction with the utility model of embodiment and to specify.Referring to Fig. 1 and Fig. 2, the positive triangle fixed support of underground laying cable comprises triangle shroud ring 2, goes up shroud ring 3 and following shroud ring 1, triangle shroud ring 2 is provided with the equilateral triangle framework, be equipped with cranse and wing limit at its three the top of the horns, the wing limit with last shroud ring 3 and following shroud ring 1, the wing limit of triangle shroud ring 2 is connected by bolt 4.The cranse of triangle shroud ring 2 is semicircle cranses, and the cranse of last shroud ring 3 also is semicircle cranse; The cranse of following shroud ring 1 is the semicircle cranse of duplex, is provided with bolt hole at its connection box middle part, is connected by the underframe of bolt with triangle shroud ring 2 equilateral triangle frameworks.The cranse inwall of triangle shroud ring 2, last shroud ring 3 and following shroud ring 1 all is equipped with abrasionproof pad 5.In this support bracket fastened side or end face is scribed or reference numerals numbering or coating color.The utility model with same numbers numbering or color can be used for the cable construction of same line, make things convenient for the staff to the identification of different circuits.
During power cable laying, earlier two single-core cables are placed on play in the semicircle cranse of shroud ring 1, again triangle shroud ring 2 and following shroud ring 1 are aligned, tight a bolt and 4 can fix this two cables.That remaining root cable is placed in the semicircle cranse of triangle shroud ring 2 upper ends, buckles well shroud ring 3 and tight a bolt and 4 can finish installation.For preventing from installing time damage cable sheath, cable sheath and triangle shroud ring 2, on the place that contacts with following shroud ring 1 of the shroud ring 3 abrasionproof pad 5 of packing into.If the utility model in the course of processing not in the side or end face is scribed or the reference numerals numbering, at this moment can be in the side or end face coat different colors according to different circuits, can distinguish the cable of different circuits, make things convenient for the staff to distinguish.
