Description
Technical field
The utility model relates to for a kind of test tool, and it is arrester test bed to be specifically related to a kind of portable 10kV.
Background technology
In checking experiment actual at the scene, when leakage current measurement under DC reference voltage U1mA and 0.75 times U1mA is carried out to 10kV lightning arrester, because during test, 10kV lightning arrester needs with very high voltage, so need 10kV lightning arrester to erect fixed placement, do power frequency reference voltage and persistent current measurement, need vertically to place and insulation against ground 10kV lightning arrester, when doing ac test, the base of lightning arrester own is not directly grounded, needs insulating supporting.And 10kV lightning arrester pull down after due to up and down for screw structural, therefore 10kV lightning arrester itself cannot be fixed, 10kV lightning arrester is supported through common instrument or other things, usually cause in test of lightning arrester process and support unstable or fall damage, danger is brought to testing crew and work, affect work efficiency, and independent 10kV lightning arrester cannot accomplish insulation against ground.Therefore a kind of testing table is needed, technical requirement below this testing table demand fulfillment: 1, controlled in quality and volume, to meet its portable, convenient, practical characteristic.2, there is certain structure can ensure the upright of lightning arrester, and have certain safe distance over the ground.3, adopt metal material as support, and special earth terminal is set, so just can ensure the good contact of test specimen and earth mat.Publication number is that the Chinese utility model of CN203941195U relates to a kind of 10kV test of lightning arrester base, it is provided with insulating mounting dish and is provided with lightning arrester putting hole at the center of insulating mounting dish, be provided with vertical bracing frame in the bottom of insulating mounting dish, after in the lightning arrester putting hole that insulating mounting disk center is stretched in one end of 10kV lightning arrester, 10kV lightning arrester vertically placed.Lightning arrester base reliably can be insulated although this patent reliably can fix lightning arrester simultaneously, and reliably can fix lightning arrester simultaneously can by lightning arrester base reliable ground.But still there is certain defect: be once to test a lightning arrester on the one hand, insulating mounting dish cost is higher on the other hand, and Chinese apparatus structure is comparatively complicated.
Summary of the invention
The defect existed in view of prior art and the reality need of test of lightning arrester, the utility model provides a kind of novel portable 10kV arrester test bed.
Disclosed in the utility model, technical scheme is:
This portable 10kV is arrester test bed, comprise base 4, support 2, it is characterized in that the insulator comprising chapeau de fer 41 and disk 42 that described base 4 is commonly used for electric system, described support 2 is irony square tube, weld together with the upper end of chapeau de fer 41 in the middle part of the lower surface of irony square tube, the upper surface of irony square tube is equidistantly opened three fixed orifices and weld three setscrew nuts 1 matched with 10kV lightning arrester stud above fixed orifice, the outer wall of chapeau de fer 41 is drilled with threaded hole and is equipped with common ground bolt 3.
Further, three described setscrew nuts 1 are coated with red, yellow, and green look respectively so that distinguish test specimen.
Further, described insulator is cap and pin type suspension insulator.
Further, described insulator is bell-shaped cap and pin type suspension insulator.
Further, described insulator is resistant suspended porcelain insulator.
Further, described insulator is two umbellate form resistant suspended porcelain insulators.
Further, described insulator is three umbellate form resistant suspended porcelain insulators.
Compared with prior art, the utility model has following features:
1, portable, convenient, practical, 2, disposablely can lay three lightning arresters, effectively can improve the work efficiency of 10kV test of lightning arrester.3, the abnormal activity existed in present lightning arrester site test process can be solved, and conveniently can complete test mission.4, special common ground end is set, to carry out reliable discharge process.5, utilize waste and old power equipment to make material, draw materials conveniently, with low cost, steadily of centre of gravity and meet electric power safety working regulation with ground dielectric level and specify.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation at another visual angle of embodiment 1.
Embodiment
Embodiment 1, see accompanying drawing 1-2.
This portable 10kV is arrester test bed, comprise base 4, support 2, it is characterized in that the three umbellate form resistant suspended porcelain insulators comprising chapeau de fer 41 and disk 42 that described base 4 is commonly used for electric system, described support 2 is irony square tube, weld together with the upper end of chapeau de fer 41 in the middle part of the lower surface of irony square tube, the upper surface of irony square tube is equidistantly opened three fixed orifices and above fixed orifice, is welded three setscrew nut 1, three setscrew nuts 1 matched with 10kV lightning arrester stud and is coated with red, yellow, and green look respectively so that distinguish test specimen.The outer wall of chapeau de fer 41 is drilled with threaded hole and is equipped with common ground bolt 3.
Utilize porcelain disk-like insulation to do base, make support steadily of centre of gravity, and meet electric power safety working regulation with the dielectric level on ground and specify; One section of metal side tube is utilized to do support, this metal side tube is equidistantly opened three fixed orifices, and three nuts matched with 10kV lightning arrester stud are welded above fixed orifice, by the square tubes soldering that processes on base, after welding is good, a stud is welded, using the common ground end of this stud as this test bracket above base.In actual application, lightning arrester is placed on support, because support and lightning arrester adopt screw to be connected, this ensures that theres lightning arrester and be connected with the reliable of support; Be placed on support by disposable for one group of three lightning arrester under normal circumstances, reduce conversion time, can increase work efficiency like this; Special common ground end is set, by ground wire, support reliably can be connected with earth mat in rig-site utilization process, ensure that residual current flows into the earth.Make testing crew can conveniently complete putting of 10kV lightning arrester, prevent lightning arrester from toppling in process of the test, safety standard complete experiment work.
