Abstract
The utility model provides a twisted obligated high voltage cable sheath. The twisted obligated high voltage cable sheath has the technical scheme that the twisted obligated high voltage cable sheath is composed of a cable and a sheath; the sheath is provided with a through hole; the cable penetrates the through hole; both ends of the sheath are respectively provided with a conical convex ring and a conical groove; the conical convex ring on one end of the sheath and the conical groove on one end of the adjacent sheath are in mutual butt joint and are orderly connected in series to the exterior of the cable to form an insulated protective sheath which can bend along with the cable. The utility model has the characteristics of reasonable design, simple structure, safety, convenient use, easy maintenance, etc.
Description
1, technical field
The utility model relates to a kind of power transmission and transforming equipment accessory, specifically a kind of tortuous reservation sheath of hv cable.
2, background technology
For the laying cost that reduces high voltage cable with reduce the obstacle that surface structures and road administration are caused, high-tension cable adopts provided underground in underground 1 meter to 2 meters dark cable trough more at present, and the ground end of cable often wants pre-buried pre-2-3 circle to use as recovery cable together respectively with holding with going out.Usually cable breaks down and is mostly occurring in the tag, fix a breakdown and just cable socket need be clipped the 30-50 centimetre, and then make joint and be connected with the cable of aerial part, curtailment partly is exactly to take to be embedded in underground tortuous pre-testing cable in the connection procedure.Being embedded in the in use existing problem of underground tortuous pre-testing cable is, the outside of single-core cable does not have coat of metal, because coat of metal can make cable self produce eddy current, increases circuit loss.Though cable adopts back-up sand again when pre-buried, lay bricks or other modes are protected; but still destroyed by construction machinery at road administration construction, building construction process unavoidably; as long as insulating covering is damaged; can cause that immediately converting equipment blast or burning cause large area blackout; not only have a strong impact on the normal electricity consumption of industrial and agricultural production and people's lives, but also the accident that might cause casualties.Good solution is not also arranged at present.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of safety shield that can effectively protect underground tortuous reservation high-tension cable is provided.
The technical solution of the utility model realizes in the following manner; put the insulation that two ends are respectively arranged with bulge loop and groove in the outside of tortuous cable, the bulge loop of sheath sheath one end and the groove of adjacent sheath one end dock mutually that the outside that is connected in cable successively forms can be with the protective sleeve of the insulation of cable bending.
The utility model has the advantages that: simple in structure, be easy to processing and install, can together crooked third good mechanical strength be arranged with cable, can prevent effectively that artificial destruction and construction from accidentally injuring and cause and have a power failure and serious accident such as hurt sb.'s feelings.
4, description of drawings
Accompanying drawing is the structural representation of tortuous reservation sheath of hv cable.
Mark in the accompanying drawing is represented respectively; Sheath 1; Cable 2; Bulge loop 3; Groove 4; Through hole 5.
5, embodiment
Below in conjunction with accompanying drawing tortuous reservation sheath of hv cable of the present utility model is done following detailed description the in detail.
Tortuous reservation sheath of hv cable of the present utility model as shown in drawings; its structure is made up of cable 2 and sheath 1; have through hole 5 in the sheath 1; cable 2 is through among the through hole 5; sheath 1 two ends are respectively arranged with taper bulge loop 3 and conical socket 4, and the taper bulge loop 3 of sheath 1 one ends docks the outside composition that is connected in cable 2 successively mutually with the conical socket 4 of adjacent sheath 1 one ends can be with the insulation protective jacket of cable 2 bendings.
Sheath 1 two ends can be respectively hemisphere bulge loop 3 and hemispherical groove 4.
Sheath 1 is to be made by plastics, fiberglass or pottery.
Embodiment
The use of tortuous reservation sheath of hv cable of the present utility model is also very convenient; as shown in drawings; cable is outside to get final product by being set on end to end with sheath; be that bulge loop is a head, groove is a tail, is set on the outside of cable successively; because bulge loop has certain scope of activities among groove; so when pre-buried cable was tortuous, the junction between the sheath can be with the cable bending, but crooked back cable is still among the protection of sheath.The processing and fabricating of sheath is general-purpose plastics or fiberglass process technology.
Tortuous reservation sheath of hv cable of the present utility model is compared with prior art; have reasonable in design, simple in structure, safe and reliable, easy to use, be easy to characteristics such as maintenance; the cable that is applicable to all size uses the protection of especially single core large-current high-voltage cable.Thereby, extensively promote the use of and will have good economic and social benefit.
Claims (3)
1, tortuous reservation sheath of hv cable; it is characterized in that sheath in have through hole; cable is through among the through hole; the sheath two ends are respectively arranged with taper bulge loop and conical socket, and the taper bulge loop of sheath one end and the conical socket of adjacent sheath one end dock mutually that the outside that is connected in cable successively forms can be with the insulation protective jacket of cable bending.
2, tortuous reservation sheath of hv cable according to claim 1 is characterized in that the sheath two ends can be respectively hemisphere bulge loop and hemispherical groove.
3, tortuous reservation sheath of hv cable according to claim 1 is characterized in that sheath is to be made by plastics or fiberglass.
