Abstract
The invention provides a method for slicing a cable joint. The method comprises the following steps: fixedly sleeving the cable joint on a rotating support shaft of a lathe; clamping a cutter on a cutter holder of the lathe; and adjusting the rotation speed of the cable joint and the feeding speed of the cutter to cut the cable joint. The method obtains a slice of the cable joint with even thickness and smooth surface.
Description
Technical field
The present invention relates to a kind of method for cable splice is cut into slices.
Background technology
In cable professional domain, cable accessory fault analysis is the work that very complicated, technical requirement is higher, particularly for cable fault more than 110kV.The reason breaking down due to the cable accessory moving is a lot, as external force, superpotential, annex inside exist defect etc., therefore usually needs failure cable annex to dissect the reason breaking down to analyze it.
The inner structure more complicated of 220kV cable splice (cable accessory a kind of), and for can analyzing failure cause (structure of the inner different layers of joint), therefore need to carry out vertical profile to huge cable accessory like this, to make required annular test piece.
Because cable splice size is larger, and this is as soft rubber material, utilize the cutting of wallpaper cutter, in chopper mode, cut or cut with manual mode, easily produce " offset tool " phenomenon, the uneven thickness of section after cutting, surface is rough and uneven in surface owing to there are obvious tool marks, causes the section cannot be for experimental analysis.
Summary of the invention
The present invention is devoted to just to overcome the above-mentioned defect of prior art and makes.Technical matters to be solved by this invention is to propose a kind of method for cable splice is cut into slices, and this method can obtain the section of even thickness, ganoid cable splice.
For solving the problems of the technologies described above, the invention provides a kind of method for cable splice is cut into slices, described method comprises the steps: described cable splice fixed cover to be located in the rotating support shaft of lathe; Clamping cutter on the knife rest of described lathe; And adjust the rotational speed of described cable splice and the feed velocity of cutter, to cut described cable splice.
Preferably, cutter comprises blade and be clamped in the handle of a knife on knife rest, and a part for blade is fixed on handle of a knife, and another part of blade stretches out handle of a knife with cutting cable splice.
Preferably, in the process of the described cable splice of cutting, by liquid soap, be lubricated.
Preferably, cable splice is cable intermediate joint more than 110kV.
The invention has the beneficial effects as follows, the present invention uses coordinating of blade and lathe, cable splice is cut, by guaranteeing under the situation of blade sharpness and rigidity, regulate the rotational speed of cable splice and the feed velocity of blade, thereby realize that the slice surface obtaining is smooth, even thickness, can better be applied to experimental analysis.
Should be appreciated that, above generality is described and the following detailed description is all enumerated and illustrative, and object is for the further instruction that the invention provides to claimed.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.Identical parts represent with identical label in the accompanying drawings.
The invention provides a kind of method for cable splice is cut into slices, the method comprises the steps:
Failure cable joint fixed cover is located in the rotating support shaft of lathe;
Clamping cutter on the knife rest of lathe, wherein, cutter comprises blade and be clamped in the handle of a knife on knife rest, and a part for blade is fixed on handle of a knife, and another part of blade stretches out handle of a knife to cut described cable, and
In the situation that guarantee sharpness and the rigidity of blade, adjust the rotational speed of cable splice and the feed velocity of cutter, to cut described cable splice, obtain the smooth section without tool marks and even thickness.
The size that in the present invention, the rigidity of blade stretches out in handle of a knife by shortening blade improves.In implementing the process of this cutting cable splice, by common soap liquid, be lubricated, the rotational speed of lathe should slow down in addition, and speed can cause blade to depart from too soon, by regulating lathe rotating speed and feed velocity, finds the best joint of cutting speed.The cable splice cutting is soft rubber material, can obtain the uniformly slicing that about 5mm is thick, and smooth surface is without tool marks when using method of the present invention to cut cable intermediate joint more than 110KV.
Section after the cable splice that method of the present invention is cut can be annular or sector-shaped slices, wherein endless chipping is cut and can obtain sector-shaped slices, Fig. 1 shows the schematic diagram of the device of implementing method of the present invention, the soft rubber material 3 that this device shows cutting knife 1 and is fixed on this device, soft rubber material is the cable splice shown in Fig. 2.
Fig. 3-Fig. 4 shows obtained endless chipping and sector-shaped slices.Fig. 5 shows breakdown channel and the electricity tree of finding in endless chipping, and Fig. 6 shows the impurity of finding in endless chipping, and Fig. 7 shows the bubble population of finding in sector-shaped slices again, and Fig. 8 shows projection, impurity and the electricity tree of finding in sector-shaped slices.
Although the present invention is illustrated with reference to accompanying drawing and preferred embodiment, obviously, for a person skilled in the art, not deviating under the prerequisite of the spirit and scope of the present invention, can make various modifications and variations to the present invention.Various change of the present invention, the content changing by appending claims and equivalent thereof contain.
