Technical field
The present invention relates to a kind of characteristic test device of insulating, especially a kind of in electric system the characteristic test device of insulating of insulating bar.
Background technology
Along with the fast development of electric utility, the continuous quickening of electrical network scale, the maintenance task of converting equipment is also day by day heavy.Insulating bar is the managing security tools and instruments that power transformation operation, test maintenance department the most often uses, Xuancheng electric company repaiies trial work district high-tension laboratory and will carry out the insulation safety test to nearly 400 insulating bars every year according to statistics, so many insulating bar is used by one line production division of company, if Insulation Test method and test instrument can not satisfy the testing requirements of rules, certainly will cause negative effect to accuracy and the security of test, thereby bring potential safety hazard for the user of insulating bar.
At present, the insulating bar test normally hangs on insulating bar head hook (height 5 can reach rice) on testing transformer, and the recycling wire is with insulating bar tail end ground connection, and then pressurization is tested.In the process that test is prepared, testing crew needs cat ladder to ascend a height, and it is insecure reliable that insulating bar hangs on high-pressure side, therefore there is certain potential safety hazard in process of the test, and workflow is loaded down with trivial details, and inefficiency has all brought certain risk and loss for testing crew and company.
Summary of the invention
The present invention is the weak point that exists in above-mentioned prior art for avoiding, and a kind of characteristic test device of insulating of insulating bar is provided, and with the short form test flow process, improves experiment work efficient, the safety and reliability of strengthen test.
The present invention be the technical solution problem by the following technical solutions.
The characteristic test device of insulating of insulating bar, its design feature are to comprise base, support and insulating bar erecting frame; Described base is rectangular frame, and the bottom that base is four jiaos respectively is provided with a roller; Described support comprises left socle and right support; Described left socle and right support include the lower frame that is fixedly installed on described base and be installed on also can be at the upper frame of vertical direction along the lower frame lifting on described lower frame; Described insulating bar erecting frame is installed on the top of described upper frame by lock-screw; Described insulating bar erecting frame bottom is fixed with a rectangular box-like crossbearer, and described crossbearer is provided with a plurality of adjustable metal buckles for fastening tested insulating bar; The push rod top at described insulating bar erecting frame top is provided with the anticorona ball of a plurality of hollows; Be provided with a hand-rail type regulating wheel on described base, be provided with on described regulating wheel be used to the stay cord that pulls upper frame to make upper frame rise along lower frame at vertical direction; The top and bottom of described lower frame are respectively equipped with top sheave and lower sheave; One end of described stay cord is fixed on regulating wheel and is wound on regulating wheel; The other end of described stay cord is walked around the lower end that is anchored on after lower sheave and top sheave in lower frame successively.
The design feature of the characteristic test device of insulating of insulating bar of the present invention also is:
Described insulating bar erecting frame is rectangular frame, is provided with the insulation full skirt of anti-pollution flashover on the outer peripheral face on the top of the vertical rod of the described insulating bar erecting frame left and right sides.
Also be provided with surveyors' staff on described crossbearer.
Described adjustable metal buckle includes clasp, spring and pull bar; Described clasp is fixed on the crossbeam of described crossbearer by the flange at its two ends, described crossbeam is provided with through hole, described pull bar passes from described through hole and the first end of pull bar be positioned at described clasp around cavity, the end of the first end of described pull bar is provided with the arc top flat, described spring housing is located on the outer peripheral face of first end of pull bar, and the diameter of described spring is greater than the diameter of described through hole; Be fixed with a spherical on the second end of described pull bar.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, proving installation of the present invention is take power test technical standard (DL/T878-2004) as design basis, by the standardized component size, and integrated test device of insulating rod, thus the accuracy and reliability of insulating bar test is increased greatly.In insulating bar process of the test in the past, all that the insulating bar head end is hung on testing transformer, adopt the mode of iron wire winding with insulating bar tail end ground connection, this coarse mode of connection does not meet specified standard size in power test technical standard (DL/T878-2004), has all brought very large negative effect for the reliability of test.And in test in the past, because the height that insulating bar hangs is very high, when determining the test effective length of insulating bar, the measurement of need to ascending a height makes the result discrepancy of measurement very large, has affected the degree of accuracy of test findings.The present invention has fixedly mounted steel tape on the insulating bar erecting frame, can measure easily the test length of insulating bar, has improved the work efficiency of insulating bar test.
2, proving installation of the present invention has used modular mentality of designing, has simplified in the process of insulating bar test and has tested link, has reduced insulating bar loading and unloading, regular time, has improved test efficiency, has reduced human cost.In test in the past, more because link is prepared in test, and the operation of need to ascending a height, insulating bar loading and unloading, set time need about 3～5 minutes, have wasted a large amount of manpower and materials.Proving installation of the present invention make insulating bar test loading and unloading, fixedly link becomes simply, the used time reduces greatly, only needs about 0.75 minute kind can complete the work that insulating bar loads and unloads, fixes.
3, proving installation of the present invention has used liftable insulating carriage, need not ascending stair and climb (need ascend a height 4 meters in the test) in the past in carrying out the insulating bar process of the test, has strengthened the security in the process of the test.Use buckle that insulating bar two ends are fixed, with respect to the suspension type method in test in the past, reduced in process of the test because the not firm falling risk that causes of contact, improved the security of test.
Proving installation of the present invention has the advantages such as human cost of high efficiency, the degree of accuracy that can improve test and security, reduction test.
