Description
Technical field
The present invention relates to a kind of method of the insulation rope being carried out power frequency withstand test.
Background technology
The insulation rope is an indispensable managing security tools and instruments in the electric system, is used by wide model because its flexibility is good, intensity is high, insulating property are strong.Its effect is: 1, can be used as during hot line job and tie up rope and transmit rope; 2, also can be used as lifting rope under the situation about meeting the demands as intensity; 3, also can be used as during non-hot line job and tie up rope and transmit rope; 4, scale also can be used as in live zone and measures chi and use (" electric power safety working regulation " regulation is forbidden to use steel tape, tape measure in live zone and had the line chi of electric conductivity) on the notes; 5, do isolation strip usefulness, separate charged and power failure equipments, show with indicating.
Because the insulation rope will directly contact with live part sometimes; Non-direct contact also is unlikely to the time because the effect of wind or other external force misses the insulation rope bumps live part and cause security incident.Regulation in " so electric power safety working regulation ": the insulation rope will be done AC voltage withstand test (rules require 105kV/0.5m).Method commonly used now when the insulation rope is done experiment is: the insulation rope is hung get up to carry out AC voltage withstand test.This way: 1, not only original but also be subjected to the influence big (as wind) of surrounding environment; 2, the insulation rope is longer, and one section one section (0.5m) tests consuming time long, relatively more clumsy simultaneously; 3, multiply is brought together when testing together, because the kelvin effect of electric current, the distribution that adds to electric field intensity is irregular, and making the electric current that flows through on every section insulation rope is different with the voltage that is born, do not reach every section purpose of carrying out AC voltage withstand test like this, this method is unavailable.
Summary of the invention
In order to overcome difficulty that above-mentioned reason brings and not enough, the invention provides a kind of method that the insulation rope is tested, this method can be carried out AC voltage withstand test to multistage insulation rope simultaneously.
Solving the technical scheme that problem of the present invention adopted is: at first design an insulation rope test-bed, stand can be designed to random length; It comprises the stand base, goes up lower conductor, insulation strut, and the stand base is made with metal, and lower conductor is welded on the stand base, and designs an earth point, is used for linking to each other with grounding body; Upper conductor is located at the lower conductor top, is connected by insulation strut between the two, and designs a wiring handle, and in order to connect test lead, last lower conductor is parallel to each other; Be provided with mobilizable arc ply-yarn drill on last lower conductor, the arc ply-yarn drill on the last lower conductor is crisscross arranged, and each curved line is fastened on the centre of corresponding top or following two arc ply-yarn drills, and the distance between the arc ply-yarn drill of per up and down two correspondences is 0.5m; Last lower conductor is that xsect is circular straight-bar or annulus or elliptical ring; Concrete test method is: on the upper and lower last lower conductor that is wrapped on the stand of insulation rope, mate each arc ply-yarn drill respectively and compress the insulation rope; High-voltage connection is connected on the wiring handle place of upper conductor, and upper conductor is as high-pressure side; Be connected on earth point place on the lower conductor with a ground wire, base is as earth potential; Upper conductor is applied voltage, can carry out AC voltage withstand test.
Because the thickness of insulation rope does not wait, arc ply-yarn drill next door all has aperture on electric conductor up and down, rotates the arc ply-yarn drill, and the end of arc ply-yarn drill can enter that the insulation rope that diameter is thinner compresses in the aperture.
Good effect of the present invention is: the test-bed that this method is used is simple in structure, makes easily, and is with low cost, handled easily; Once can carry out Insulation Test, high efficiency to very long insulation rope; Be not subjected to the influence of surrounding environment, electric current that flows through and the voltage that is born are impartial on every section insulation rope, and test findings is accurate; By regulating each arc ply-yarn drill, can carry out AC voltage withstand test to the insulation rope of different thicknesses.
Description of drawings
Accompanying drawing is the user mode synoptic diagram of the inventive method.
Embodiment
As shown in drawings, at first design an insulation rope test-bed, this stand can be made any length as required; Stand base 1 usefulness metal is made, and welding one lower conductor 2 at one end designs an earth point 3 on the stand base 1, is used for linking to each other with grounding body; Connect an insulation strut 4,5 respectively at lower conductor 2 both sides vertical directions, the epoxy resin enhancement mode glass fibre solid post that insulation strut 4,5 adopts excellent performance is as the major insulation material, and dielectric strength will be higher than 105kV far away; Two insulation strut 4,5 upper ends are connected by upper conductor 6, at one end design a wiring handle 9, in order to connect test lead, last lower conductor 6,2 is copper cylinder or copper pipe, last lower conductor 6,2 is isometric and be parallel to each other, and the insulation strut 4,5 of last lower conductor 6,2 and both sides is formed a framed structure; On upper conductor 6 and below the lower conductor 2, be equipped with mobilizable arc ply-yarn drill 7, arc ply-yarn drill 7 on the last lower conductor 6,2 is crisscross arranged, each arc ply-yarn drill 7 is located at the centre of corresponding top or following two arc ply-yarn drills 7, distance between the arc ply-yarn drill 7 of per up and down two correspondences is 0.5m, promptly as shown in drawings, from a point to the b point, from the b point to the c point, by that analogy, be 0.5m.Because the thickness of insulation rope 10 does not wait, arc ply-yarn drill 7 next doors all have aperture 8 on last lower conductor 6,2, rotate arc ply-yarn drill 7, and the end of arc ply-yarn drill 7 can be inserted the aperture 8 interior insulation ropes 10 that diameter is thinner and be compressed.
Concrete test method is: be wrapped on the stand on the lower conductor 6,2 below the arc ply-yarn drill 7 insulation rope 10 is upper and lower, mate each arc ply-yarn drill 7 respectively and compress insulation rope 10; High-voltage connection is connected on wiring handle 9 places of upper conductor 6, and upper conductor 6 is as high-pressure side; Be connected on earth point 3 places on the lower conductor 2 with a ground wire, stand base 1 is as earth potential; Upper conductor is applied voltage, can carry out AC voltage withstand test, test is finished, and pulls down the insulation rope and can use.
