Description
Technical field:
The present invention relates to a kind of substation cable hole protector, belong to cable laying site technology field.
Background technology:
Often need to lay first and second cable in the installation of daily transformer station, technological transformation process.When cable carry out pulling at levels cable wellhead, install time, cable insulation crust can rub with cable wellhead edge, causes cable sheath damage in insulation, reduces the insulation level of cable, has had a strong impact on the security of operation of transformer station.After cable failure, searching of fault changes the need of work plenty of time with cable, not only adds the unsteadiness of operation of power networks and the work difficulty of maintainer, and wastes a large amount of human and material resources costs.
Summary of the invention:
The object of the invention is to overcome the deficiency of prior art and provide a kind of structure simple, easy to use, safe and reliable, applied widely, cost is low, improves the operation stability of electrical network, the transformer station first and second cable aperture protector of increasing economic efficiency.
Object of the present invention can be reached by following measure: a kind of substation cable hole protector, it is characterized in that it comprises two adjustable arc plates, the two ends of adjustable arc plate are provided with connection arc, arc is connected and fixed respectively by connection arc between two adjustable arc plate two ends, connecting arc inserts in fixing arc, metal tie rods is equipped with in each adjustable arc plate, metal tie rods is connected with fixing arc, metal tie rods overcoat has two adjustable retainer rings, adjustable retainer ring is connected with adjustable arc plate, each fixing arc is equipped with two fixing ears, each fixing ear all has and is connected and composed with the connecting screw bar being connected two fixtures by two fixtures.
In order to realize object of the present invention further, described fixing arc and adjustable arc plate are φ 100 metal or resin pipe and are divided into two the arc made, and metal tie rods is φ 16 Metallic rod.
The present invention can produce following good effect compared with the prior art: present invention substantially reduces cable aperture edge and give prominence to burr and sharp parts to the damage of cable insulation crust, safeguard procedures are covered cable aperture sharp parts, decrease friction, available protecting cable insulation crust, thus significantly reduce one, secondary cable is laying, because the damage that burr causes cable outer insulation jacket is given prominence at cable aperture edge in installation and operation process, cable is better protected, reduce the cable bad probability in cable operation and laid processes, reduce one, the fault that secondary cable causes because of external force, ensure one, secondary cable property safe and reliable to operation, effectively alleviate intensity of workers.
The present invention can effectively solve because external force to cause the various drawbacks of damage to cable in current transformer station first and second cable laying running, and it has:
1. structure is simple, easy to use.
Fixing arc of the present invention and adjustable arc plate are made by carrying out metal steel pipe (pitch tube) simply cutting to be divided into two, and just can be applied on cable laying mouth, do not need to carry out complex operations, anyone can make.In addition, due to fixing arc and adjustable arc plate bulk less, lighter in weight, the single installation just can carrying out cable port protective plate, uses more convenient.
2. applied widely.
Generally be applicable to current transformer station first and second cable laying import and export and line cord lays import and export.
3. draw materials conveniently, cost is lower.
The simple processing and fabricating such as the steel pipe (pitch tube) that fixing arc of the present invention and adjustable arc plate can utilize job site common, material is very easy to find, and due to material volume general less, can be able to make of the leftover bits and pieces of above-mentioned material completely, cost is very cheap.
4. fail safe improves.Before non-installing cables lays safeguard procedures, first and second cable is when laying by cable port, and cable sheath has damage more, and when particularly laying a cable, because cable is heavier, flexibility is not high, and cable sheath damage is more serious.By after the cable wellhead of newly-built transformer station has installed the present invention additional, the breakage of first and second cable has obviously reduced.
5, economic benefit improves.
After having installed the present invention additional, the spoilage of cable has reduced greatly, and the equipment power failure caused because of cable bad and operation of power networks accident reduce in a large number, improve the operation stability of electrical network, facilitate the lifting of corporate economy's benefit.

Embodiment:
Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated:
Embodiment: a kind of substation cable hole protector (see Fig. 1-Fig. 4), it comprises two adjustable arc plates 2, the two ends of adjustable arc plate 2 are provided with and connect arc 9, fixing arc 1 is flexibly connected respectively by connection arc 9 between two adjustable arc plate 2 two ends, connecting arc 9 inserts in fixing arc 1, connect arc 9 and guarantee fixing arc 1 and adjustable arc plate 2 one-tenth 90 degree of angles, metal tie rods 5 is equipped with in each adjustable arc plate 2, metal tie rods 5 is connected with fixing arc 1, metal tie rods 5 overcoat has two adjustable retainer rings 6, adjustable retainer ring 6 is connected with adjustable arc plate 2, adjustable arc plate 2 is rotatable, can regulate according to cable bend radian.Each fixing arc 1 is equipped with two fixing ears 3, each fixing ear 3 all has and is connected and composed with the connecting screw bar 7 being connected two fixtures 8 by two fixtures 8, the openings of sizes of fixing ear 3 can be regulated by connecting screw bar 7, thus be fixed.Fixing arc 1 adopts φ 100 metal or resin pipe to be divided into two with adjustable arc plate 2 and makes, and metal tie rods 5 is φ 16 Metallic rod.
