Abstract
The invention discloses a light composite insulating rod with good operation stability for a loop resistance test. The light composite insulating rod comprises a first section including a wiring clamp, a plurality of middle sections of insulating rods, a bottom insulating rod, and a tail joint, a transition joint is arranged between the first section and the middle sections of the insulating rods, a test current wire is directly poured into a glass fiber epoxy resin composite insulating rod to form current-guiding copper conductors, the current-guiding copper conductors in each insulating rod are connected via copper threaded joints at two ends of the conductors, a test voltage wire penetrates through the middle of the insulating rod, the current wire is connected with the wiring clamp at the top of the first section of the insulating rod, the current wire and the voltage wire are led out from the tail joint and connected with a loop resistance test apparatus, and the voltage wire is pressed in from a side wire slot of the tail joint. According to the light composite insulating rod, the structure is reasonable, the operation stability is good, and the usage is safe.
Description
The application is application number: the divisional application of 201310210844.4, the applying date: 2013.5.31, title " loop resistance test lightweight compound inslation bar ".
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, is also the key component ensureing that power system security effectively runs.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 outside fit system overlapped.In which, due to insulating bar and test wire is heavier, p-wire tilts naturally etc. insulating bar will be produced to larger horizontal pull, in addition, wind-force traction also has considerable influence to the stability of insulating bar.The design of conventional circuit resistance test insulating bar and technologic imperfection make to there is potential safety hazard in high-potting process, in recent years the personal flash burn accident having generation to cause thus more.In addition, in electric system production scene during actual use, often there will be the thicker situation needing friction oxide layer of altitude plant surface oxide layer, the jointing clamp surface of contact of existing use is comparatively level and smooth, friction is too little, uses inconvenience.On-the-spot in actual production, operating personnel also feel inconvenient operation, are therefore necessary to improve conventional circuit resistance test insulating bar.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the operational stability of insulating bar is good, the loop resistance test lightweight compound inslation bar of use safety.
Technical solution of the present invention is:
A kind of loop resistance test lightweight compound inslation bar, is characterized in that: comprise containing the first segment of jointing clamp, more piece middle node insulating bar, most minor details insulation bar and pigtail connection successively; Between first segment and middle node insulating bar, crossover sub is set; It is inner that test current line is directly cast in glass epoxy resin compound inslation bar, forms water conservancy diversion copper conductor, often saves between the water conservancy diversion copper conductor in insulating bar and connected by the copper threaded connector at its two ends; Test pressure-wire passes in the middle of insulating bar, and current line saves insulating bar top at head and is connected with jointing clamp, and current line, pressure-wire are drawn from pigtail connection and be connected with circuit resistance tester device, and pressure-wire is from the side wire casing press-in pigtail connection.
Described crossover sub is provided with connection terminal and current line is connected with the terminals of jointing clamp, and crossover sub is provided with pressure-wire through hole.
Protective jacket is provided with bottom minor details insulating bar.
The present invention is rational in infrastructure, reduces insulating bar and to be put to the test the impact of line tractive force and wind-force effect.Test current line is directly cast in insulating bar inside, forms baffle; Test pressure-wire, from passing in the middle of insulating bar, becomes in the same way with insulating bar, decreases horizontal pull and wind-force that p-wire produces insulating bar to the impact of insulating bar stability; Alleviate the general assembly (TW) of insulating bar and test wire.Because water conservancy diversion copper conductor is cast in insulating bar inside, water conservancy diversion copper conductor surface is wrap insulate layer not, and insulating bar outer wall realizes External Insulation; P-wire vertically, not tilts, and reduces the required test wire length of test, thus can alleviate the general assembly (TW) of insulating bar and test wire.
By test wire being cast on insulating bar inwall, reduction test wire and wind-force are to the tractive force of insulating bar, reduce the overall weight of insulating bar and test wire in process of the test to a certain extent, to improve the stability of insulating bar, ensure the personal safety of user, meet high-voltage test on-site practical application request.
