Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 has schematically shown the structure according to an embodiment of the utility model insulating support;
Fig. 2 has schematically shown the structure according to an embodiment of the utility model insulating bar;
Fig. 3 has schematically shown the sectional structure according to an embodiment of the utility model insulating bar.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Fig. 1 has schematically shown the structure according to an embodiment of the utility model insulating support, Fig. 2 has schematically shown the structure according to an embodiment of the utility model insulating bar, in conjunction with referring to Fig. 3, as shown in the figure, in embodiment of the present utility model, a kind of insulating bar assembly is provided, comprising: insulating bar 20, it comprises: insulating case 201, and the center has through hole; Conducting metal bar 203 is embedded in the through hole of described insulating case 201; Insulating support 40 is used for fixing described insulating bar 20, and it comprises: vertical rod 401; Base 403 is connected with described vertical rod 401 lower ends; Fixture 405 is arranged in the described vertical rod 401.Employing is according to insulating bar assembly of the present utility model, overcome carry out cable voltage, during high pressure withstand voltage test such as GIS is withstand voltage, owing to use thinner lead-in wire to pass insulating bar, the insulation of insulating bar can not be born very high electric field strength, can because of safe distance deficiency cause the insulating bar high potential to discharge over the ground, there are problems such as potential safety hazard, and then reached safety and practical effect.
Can make different specifications according to test voltage grade at ordinary times by the insulating case 201 of thickening insulating bar 20,, also avoid causing the waste of unnecessary cost of manufacture because of the low class of insulation height of test voltage grade with convenient need of work at ordinary times.Making insulating bar 20 can keep our test voltage at ordinary times gets final product.This insulating bar 20 is than the dielectric strength height of common insulating bar, and the centre is embedded with conducting metal bar 203, requires to use different size conducting metal bar 203 according to different tests, has so just often avoided the phenomenon that dally over one's work because went between thick.And common insulating bar generally all is hollow, and the general smoother of outer surface is easy to wiping, is not easy dirty.But inner face is all very coarse, is easy to dirty.The filthy state on insulating bar surface is very big to the flashover performance impact of insulating bar.Show that according to result of the test behind the surface filth, particularly deposit makes moist and when conducting electricity, anti-flashover strength can seriously reduce.This is because have dirty and atmospheric humidity when higher when the insulating bar surface, more becomes inhomogeneous along the voltage distribution of insulating bar, and glow discharge will appear in the High-Field strength, make the characteristics that have transition along the leakage current on insulating bar surface.If conducting metal bar 203 of embedding in insulating bar 20, it is solid to make that insulating bar 20 becomes, generation be because of the insulating bar 20 dirty phenomenons of discharge that cause will reduce greatly, so not only makes our the finishing of not only fast but also safety of working, and I have increased the life-span of insulating bar 20 greatly.
Because insulating case 201 thickenings of insulating bar 20, middle conducting metal bar 203 are relatively slightly, make that insulating bar 20 is heavier, causing at work, setting up of insulating bar 20 is difficult to fixed stably with general insulating tape, insulation rope.So we also need to make 40 pairs of insulating bars 20 of an insulating support and are fixed according to actual needs, insulating support vertical rod 401 also needs the dielectric strength that reaches certain, make a fixture 405 at the top of support, can make insulating bar 20 be fixed on the fixture 405 and stable.Because when testing at ordinary times, high-voltage connection sometimes can be very long, and it is very thick again to go between.In order to make insulating support 40 more stable.So insulating support 40 is provided with base 403, base 403 can be four heavier Convenient tables that can free shrink, so that make that insulating support 40 is stable, certainly, base 403 also can be a disk.
Insulating bar 20 is made the middle entity insulating bar that is embedded with conducting metal bar 203, and insulating bar 20 outer surface insulation against ground degree can reach power frequency 100KV voltage, can not discharge by some beyond thought smaller spaces after guaranteeing.Preferably, the radius of conducting metal bar 203 is 1mm-3mm, and guaranteeing by higher test current, the length of insulating bar 20 is 2m-3m, to use under the convenient various different situations.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Because adopt according to insulating bar assembly of the present utility model, so overcome carry out cable voltage, during high pressure withstand voltage test such as GIS is withstand voltage, owing to use thinner lead-in wire to pass insulating bar, the insulation of insulating bar can not be born very high electric field strength, can because of safe distance deficiency cause the insulating bar high potential to discharge over the ground, there are problems such as potential safety hazard, and then reached safety and practical effect.Use this insulating bar assembly, dielectric strength has increased, and corresponding safe arcing distance has also increased, and former more recurrent electric discharge phenomena not enough because of dielectric strength, that safe distance is not enough etc. causes are effectively solved.Insulating bar and insulating support are used, and have saved a lot of insulation of fixed insulation bar and lead wire insulation rope, insulating tape etc. in the past article.Insulating bar in the past often causes discharge inadequately because of insulating, and insulating bar punctures, and makes insulating bar lose use value.Insulating bar after the improvement can use repeatedly, effectively reduces job costs.Frequent discharge all has some losses for testing equipment with by test equipment; especially very big for the testing equipment loss; insulating bar has also been protected testing equipment after improving virtually, makes the testing equipment life-span increase, and the personal safety for the staff has also played very big protection at work.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
