Abstract
The invention discloses a lightweight composite insulating rod for loop resistance testing. The lightweight composite insulating rod sequentially comprises a first segment with a splicing clamp, a plurality of middle insulating rods, a tail-segment insulating rod and a tail joint. A transition joint is arranged between the first segment and the middle insulating rods. A testing current wire is poured inside the glass-fiber epoxy composite insulating rods to form conductive copper conductors. The conductive copper conductor in each of the insulating rods is connected through copper threaded joints at two ends of each conductive copper conductor. A testing voltage wire penetrates the middle of the insulating rods. The current wire is connected to the splicing clamp on the top of the first segment. The voltage wire and the current wire penetrate the tail joint to be connected to a loop resistance tester, and the voltage wire is pressed in a side groove of the tail joint. The lightweight composite insulating rod is reasonable in structure, good in operational stability and safe to use.
Description
Technical field
The present invention relates to a kind of loop resistance test lightweight compound inslation bar.
Background technology
High-potting is the important component part of electrical test, also is to ensure the effectively key component of operation of power system security.In the process of high-potting, ensure that the safety of testing crew and equipment is top priority, particularly personal safety.Conventional circuit resistance test insulating bar and p-wire adopt the fit system of outside overlap joint.In this mode, owing to insulating bar and test wire is heavier, p-wire tilts naturally etc. will produce bigger horizontal pull to insulating bar, in addition, the wind-force traction also has considerable influence to the stability of insulating bar.Conventional circuit resistance test insulating bar design and technologic imperfection make and have potential safety hazard in the high-potting process, in recent years the personal flash burn accidents that have generation to cause thus more.In addition, when the actual use in electric system production scene, the situation of the thicker needs of altitude plant surface oxide layer friction deoxidation layer occurs through regular meeting, the jointing clamp surface of contact of existing use is level and smooth, friction is too little, uses inconvenient.At the actual production scene, operating personnel also feel inconvenient operation, therefore are necessary conventional circuit resistance test insulating bar is improved.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, the operational stability of insulating bar is good, uses the loop resistance test lightweight compound inslation bar of safety.
Technical solution of the present invention is:
A kind of loop resistance test lightweight compound inslation bar is characterized in that: comprise segmentum intercalaris insulating bar in the first segment that contains jointing clamp, the more piece, minor details insulation thick stick and afterbody joint successively; Between first segment and middle segmentum intercalaris insulating bar, crossover sub is set; Test electricity consumption streamline directly is cast in glass epoxy resin compound inslation bar inside, forms the water conservancy diversion copper conductor, and the copper threaded connector by its two ends between the water conservancy diversion copper conductor in every joint insulating bar connects; Test is passed in the middle of insulating bar with pressure-wire, and the electric current line saves the insulating bar top at head and is connected with jointing clamp, and electric current line, pressure-wire are drawn with the circuit resistance tester device from the afterbody joint and be connected, and pressure-wire is pressed into from the side wire casing on the afterbody joint.
Described crossover sub is provided with connection terminal the electric current line is connected with the terminals of jointing clamp, and crossover sub is provided with pressure-wire and passes the hole.
Minor details insulating bar bottom is provided with protective jacket.
The present invention is rational in infrastructure, reduces the be put to the test influence of line tractive force and wind-force effect of insulating bar.Test electricity consumption streamline directly is cast in insulating bar inside, forms baffle; Test is passed in the middle of the insulating bar with pressure-wire, becomes in the same way with insulating bar, has reduced horizontal pull that p-wire produces insulating bar and wind-force to the influence of insulating bar stability; Alleviated the general assembly (TW) of insulating bar and test wire.Because the water conservancy diversion copper conductor is cast in insulating bar inside, water conservancy diversion copper conductor surface is the wrap insulate layer not, and the insulating bar outer wall is realized external insulation; P-wire vertically, do not tilt has not reduced the required test wire length of test, thereby can alleviate the general assembly (TW) of insulating bar and test wire.
By test wire being cast on the insulating bar inwall, reduce test wire and wind-force to the tractive force of insulating bar, reduce the overall weight of insulating bar and test wire in the process of the test to a certain extent, to improve the stability of insulating bar, ensure user's personal safety, satisfied the on-the-spot practical application request of high-potting.
