Technical field
The present invention relates to a kind of insulation characterisitic proving installation, especially a kind of in electric system the insulation characterisitic proving installation of insulating bar.
Background technology
Along with the fast development of electric utility, the continuous quickening of scale of power, the maintenance task of converting equipment is also heavy day by day.Insulating bar is the managing security tools and instruments that power transformation operation, test maintenance department the most often use; Xuancheng electric company repaiies trial work district high-tension laboratory every year and will carry out the insulation safety test to nearly 400 insulated bars 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 the 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 (height 5 can reach rice) on the testing transformer with insulating bar head hook, utilizes lead with insulating bar tail end ground connection again, and pressurization makes an experiment then.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 the 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 the above-mentioned prior art for avoiding, and a kind of insulation characterisitic proving installation of insulating bar is provided, and with the short form test flow process, improves experiment work efficient, strengthens the security and the reliability of test.
The present invention adopts following technical scheme for the technical solution problem.
The insulation characterisitic proving installation of insulating bar, its design feature are to comprise base, support and insulating bar erecting frame; Said base is a rectangular frame, and the bottom that base is four jiaos respectively is provided with a roller; Said support comprises left socle and right support; Said left socle and right support include the lower frame that is fixedly installed on the said base and be installed on also can be at the upper frame of vertical direction along the lower frame up-down on the said lower frame; Said insulating bar erecting frame is installed on the top of said upper frame through lock-screw; Said insulating bar erecting frame bottom is fixed with a rectangular box-like crossbearer, and said crossbearer is provided with a plurality of adjustable metal buckles that are used for fastening tested insulating bar; The push rod top at said insulating bar erecting frame top is provided with the anticorona ball of a plurality of hollows; On said base, be provided with a hand-rail type adjustment wheel, said adjustment wheel is provided with and is used to spur the stay cord that upper frame makes that upper frame rises along lower frame at vertical direction; The top and bottom of said lower frame are respectively equipped with top sheave and lower sheave; One end of said stay cord is fixed on the adjustment wheel and goes up and be wound on the adjustment wheel; The other end of said stay cord is anchored on the lower end in lower frame after walking around lower sheave and top sheave successively.
The design feature of the insulation characterisitic proving installation of insulating bar of the present invention also is:
Said insulating bar erecting frame is a rectangular frame, and the outer peripheral face on the top of the vertical rod of the said insulating bar erecting frame left and right sides is provided with the insulation full skirt of anti-pollution flashover.
Also be provided with surveyors' staff on the said crossbearer.
Said adjustable metal buckle includes clasp, spring and pull bar; Said clasp is fixed on the crossbeam of said crossbearer through the flange at its two ends; Said crossbeam is provided with through hole; Said pull bar passes from said through hole and first end of pull bar is positioned at the cavity that said clasp centers on; The end of first end of said pull bar is provided with the arc top flat, and said spring housing is located on the outer peripheral face of first end of pull bar, and the diameter of said spring is greater than the diameter of said through hole; Be fixed with a spherical on second end of said pull bar.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, proving installation of the present invention is a design basis with power test technical standard (DL/T878-2004), through the standardized component size, and integrated insulating bar test unit, thus the accuracy and reliability of insulating bar test is increased greatly.In insulating bar process of the test in the past; All be that the insulating bar head end is hung on the testing transformer; The mode that adopts the iron wire winding is with insulating bar tail end ground connection; This coarse mode of connection does not meet specified standard size in the power test technical standard (DL/T878-2004), has all brought very big negative effect for the reliability of test.And in test in the past, because the height of insulating bar suspension is very high, when confirming the test effective length of insulating bar, the measurement of need ascending a height, it is very big to make that the result who measures comes in and goes out, and has influenced the degree of accuracy of test findings.The present invention has fixedly mounted steel tape on the insulating bar erecting frame, can measure the test length of insulating bar easily, 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 ascending a height, insulating bar loading and unloading, set time need about 3～5 minutes, have wasted lot of manpower and material resources.Proving installation of the present invention make insulating bar test loading and unloading, fixedly link becomes simply, the time spent reduces greatly, only needs about 0.75 minute kind can accomplish the work that insulating bar loads and unloads, fixes.
3, proving installation of the present invention has used liftable insulation bracing frame, in carrying out the insulating bar process of the test, need not ascending stair and climbs (need ascend a height 4 meters in the test) in the past, has strengthened the security in the process of the test.Used buckle that the insulating bar two ends are fixed,, reduced in process of the test because the not firm falling risk that causes of contact has improved the security of testing with respect to the suspension type method in the test in the past.
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.
