Fig. 1 is the utility model one-piece construction and example work synoptic diagram;
Embodiment
As Fig. 1, it is configured to the utility model by two identical propping up, and support comprises that the metal frame 1 on top and the bearing soleplate 4 of bottom are provided with the post composite insulator 3 that has been used for the support and connection effect between metal frame 1 and bearing soleplate 4; On metal frame 1, distribute and be provided with U type ring 2; This metal frame 1 is a stainless steel frame, has the corrosion of being difficult for, smooth surface, the advantage that conducts electricity very well.Adopt the utility model two cover same structures to constitute testing table, be used to support bar type insulation Work tool 8 two ends of test usefulness.
The utility model is provided with universal wheel strap brake 5 in bearing soleplate 4 bottom surfaces, convenient moving.
The utility model is provided with earthing screw 6 at post composite insulator 3 centers, guarantees this utility model reliable ground, has improved safe reliability.Stainless steel has all been adopted in all bolts connections of using simultaneously.
The basic skills of insulation Work tool withstand voltage test be utilize transformer with the 220V power conversion to the bar type required rated voltage that applies of Work tool that insulate, by observing this insulation Work tool situation of withstand voltage at the appointed time, Work tool was breakdown if should insulate, then be judged to be defective, if by withstand voltage test, after being judged as qualified instrument, stick conformity certification, can in the official hour section, put in the electrical production work and go.
The utility model method for making is:
1. post composite insulator 3 of the present utility model and universal wheel strap brake 5 all can directly be buied.Stainless steel framework 1 can be dismantled, and applying 2 meters stainless steel conductors of 100A current measurement galvanic circle resistance is 72u Ω, is difficult for corrosion, smooth surface; Production process is simple, the requirement of Pass Test.For how designing the shape that live end is a stainless steel framework 1, we have carried out labor: at first, support is wanted U-loop can be installed easily, so that place the insulation Work tool; The second, support can not be too wide, prevents to produce in pressure process floating potential; The 3rd, support is too high, and poor stability is unfavorable for the testing crew operation; Analyze all multifactor after, we tentatively are defined as rectangle with the shape of support, specification is: 80 * 20cm.But because tetragonal not stationarity, we install a stainless steel bracing frame additional in the middle of rectangular support frame, prevent deformation of timbering.Therefore develop rectangle stainless steel framework 1.
2. the utility model is according to the rated capacity of testing transformer, and the purpose that makes things convenient for the loading and unloading of bar type insulation Work tool, therefore U type ring 2 has been determined in design, on selecting, makes material of stainless steel material, because can be to bar type insulation rod insulation course not damaged, for quantity of installing and interval, simultaneously also according to testing the rated capacity that becomes, and the purpose that makes things convenient for the loading and unloading of bar type insulation Work tool, determine that rectangular support frame and U type ring 2 are of a size of every interval 10cm a U type ring 2 is installed, so we are designed to 16 with the quantity of U type ring 2.
3. the utility model bearing soleplate (4) is by simulation bearing test (16 110kV link rod weight), we are the specification of 80 * 40 * 1cm with base designs, the steel plate of employing 8mm is reinforced and is increased the weight of, connect with stainless-steel tube all around, and the installation diameter is the braking universal wheel of 5cm bottom steel plate, both convenient fixing, stability has also obtained reliable assurance.
4. the utility model has been installed earth stud 6 in stainless steel framework 1 bottom, and specification is 12 * 40mm, guarantees this utility model reliable ground, has improved safe reliability.Stainless steel has all been adopted in all bolts connections of using simultaneously.
