Abstract
Disclosed in the invention is a novel protection casing tube for a high-voltage cable. The protection casing tube comprises a metal casing tube with a breaking seam at a side wall; a welding tube is arranged in the breaking seam; and the welding tube and the metal casing tube are welded. According to the invention, because the breaking seam is arranged at the side wall of the metal casing tube and the welding tube is used for filling of the breaking seam, a high-voltage cable protection function can be realized and induced currents can be effectively prevented from forming a loop in the metal casing tube to reduce heat energy generation, thereby reducing the influence on the metal casing tube by the induced currents to a great extent and improving the security performance of the protection casing tube to some extent. Because the metal casing tube is formed by welding of a plurality of metal casing tube bodies and a plurality of welding tubes, parts of metal casing tube bodies can be laid firstly during the using process and only breaking seams for high-voltage wire inserting are needed to be left at the metal casing tube bodies; and after the high-voltage wires are inserted into the metal casing tube bodies, the welding is carried out, the laying can be carried out conveniently.
Description
Technical field
The present invention relates to electrical equipment technical field, particularly relate to a kind of Novel high-voltage cable protective casing.
Background technology
As everyone knows, electric energy is one of requisite energy in people's daily life, in order to reduce the proportion of goods damageds of electric energy, improves the long-distance transmissions ability of electric energy, and people often adopt high-tension cable to realize efficient, the remote transmission of electric energy.At present, in order to protect high-tension cable, traditional way is that traditional protective casing mainly is divided into two kinds at the outer parcel of high-tension cable one deck protective casing, and a kind of is the PVC plastic tube, and another is the coating steel pipe with anti-corrosion function; But find by long-term practice, there is following defective in above-mentioned two kinds of protective casings, at first, because the major defect of PVC plastic tube is that insufficient strength is high, therefore in work progress, people often can have a mind to or damage unintentionally the high-tension cable in the protective casing, and then on people's industry and the generation impact to a certain degree of living; Secondly, although coating steel pipe has higher intensity, but since high-tension cable in use, around it, can produce alternating electromagnetic field, therefore at the inner induced current that produces of coating steel pipe, be also referred to as current vortex, this induced electricity fails to be convened for lack of a quorum and causes the coating steel pipe heating, and then cause electric energy loss, when induced current is excessive, also there is simultaneously certain potential safety hazard.Seem particularly important so design and develop the Novel high-voltage cable that a kind of intensity is high, coefficient of safety is high with protective casing.
Summary of the invention
The technical problem to be solved in the present invention is: the Novel high-voltage cable that a kind of intensity is high, coefficient of safety is high protective casing is provided.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of Novel high-voltage cable protective casing comprises that sidewall is provided with the metal sleeve of breaking joint, is provided with welded pipe in described breaking joint, mutually welding between described welded pipe and the metal sleeve.
As optimal technical scheme, the present invention has also adopted following technical scheme:
Be provided with at least two breaking joints at a metal sleeve, the central axes of described breaking joint and metal sleeve.
The arc length of described breaking joint is that 1/8th of metal sleeve circumference arrives sixth.
Advantage and good effect that the present invention has are: the present invention arranges breaking joint by the sidewall at metal sleeve, by welded pipe breaking joint is filled simultaneously, therefore when satisfying the high-tension cable defencive function, can prevent effectively that induced current from forming the loop in metal sleeve, reduced the generation of heat, can reduce to a great extent the impact that induced current produces metal sleeve, also improve simultaneously the security performance of protective casing on a lot of degree; Because metal sleeve of the present invention can form by a plurality of metal sleeves and a plurality of welded pipe welding, therefore in use, can lay first the part metals sleeve pipe, as long as leave a breaking joint that can supply high-voltage line to roll off the production line at metal sleeve, after high-voltage line rolls off the production line to the metal sleeve, weld again, therefore lay more convenient.
Description of drawings
Fig. 1 is the first specific embodiment structural representation of the present invention;
Fig. 2 is the second specific embodiment structural representation of the present invention.
Wherein: 1, metal sleeve; 2, welded pipe.
Embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, Fig. 2, a kind of Novel high-voltage cable protective casing comprises metal sleeve 1 and welded pipe 2; Wherein: the sidewall of metal sleeve 1 is provided with breaking joint, and welded pipe 2 is arranged in the described breaking joint, mutually welding between welded pipe 2 and the metal sleeve 1.On a metal sleeve 1, one or many breaking joints can be set, as described in Figure 1, be provided with a breaking joint at a metal sleeve 1, two schemes is in use arranged, scheme one at first places welded pipe 2 in the underground groove, then welded pipe 2 is placed in the breaking joint, after welding is finished high-tension cable is penetrated in the metal sleeve 1; Scheme two, at first welded pipe 2 is placed in the underground groove, then high voltage cable is pressed in the metal sleeve 1 from breaking joint, subsequently welded pipe 2 is placed in the breaking joint, welding is finished and is buried soil and get final product.For the ease of the processing of metal sleeve 1 and follow-up welding, the breaking joint in above-mentioned two specific embodiments and the central axes of metal sleeve 1; The arc length scope of breaking joint is that 1/8th of metal sleeve 1 circumference arrives sixth.Simultaneously, for the impact that prevents from getting rusty metal sleeve 1 being produced, metal sleeve 1 in this specific embodiment and welded pipe 2 all adopt the metal material with anticorrosive function to make, and metal sleeve 1 and welded pipe 2 can be selected same material, also can select different materials.
Above embodiments of the invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
Claims (3)
