Detailed description of the invention
As depicted in figs. 1 and 2, large-sized cable of the present utility model puts take-up and proving installation, comprise left socle 1 and right support 2, left socle 1 and right support 2 are rotatably connected to a main shaft 4 respectively by bearing 3, main shaft 4 is provided with cylinder 5, cylinder about 5 two ends are respectively equipped with right baffle-plate 6 and the right baffle plate 7 that external diameter is greater than cylinder 5, casing 8 is provided with on the left of described left socle 1, casing 8 is built with storage battery, casing 8 is provided with electrical motor 9 and change speed gear box 10, electrical motor 9 is in transmission connection by change speed gear box 10 one end with main shaft 4, change speed gear box 10 sidepiece is provided with the control lever 11 for manipulating change speed gear box 10 speed change, main shaft 4 is coaxially provided with the connecting cylinder 12 being positioned at left socle 1 and right baffle-plate 6 support, insulation sleeve 13 is arranged with outside connecting cylinder 12, insulation sleeve 13 circumferential outer surface circumferentially offers four circular grooves 14, copper ring 15 is equipped with in each circular groove 14, the relative both sides of copper ring 15 are respectively equipped with the first conductive contact 16 and the second conductive contact 17, four the first conductive contacts 16 are connected to one piece of copper bar 18, four pieces of copper bar 18 outer ends are provided with touch block 19, right baffle-plate 6 is provided with wire hole 20, be wrapped in one end of the cable on cylinder 5 left successively through wire hole 20, copper ring 15 is penetrated from the second conductive contact 17, be fixed on touch block 19 after the first conductive contact 16 passes.
Right baffle-plate 6 is connected by binding bolt 21 with cylinder 5 respectively with right baffle plate 7.
Be connected by flat key 22 between connecting cylinder 12 with main shaft 4.
The diameter 2-4cm larger than cable size of wire hole 20, is convenient to like this through cable.
The utility model put receive cable time, first one end of cable is connected on touch block 19 through wire hole 20, actuating motor 9, drives main shaft 4 by change speed gear box 10, cylinder 5 rotates together with connecting cylinder 12, so just can carry out putting receipts wireline operation.After letting slip or receiving cable, can test cable, test event as megger test, leakage current test, DC voltage withstand test, dissipation factor test, AC voltage withstand test etc.
1, megger test: need when carrying out the insulation measurement of cable to measure the insulation resistance between the crust of cable and heart yearn or between crust or between heart yearn.The groundwork measuring insulation resistance is similar with the measurement of conventional, electric-resistance, also be add a comparatively galvanic current pressure at the two ends of test product, then by measuring instrument, the size of current that test product flows through and the relation of time are showed, thus through the time dependent curve of insulation resistance that can obtain sample of cable that converts, curve can show the insulating resistance value of certain specified time.For the cable that volume ratio is larger, the concept of absorptance more can describe the problem under normal circumstances, therefore replaces the result of insulation measurement with it.Among actual measurement of engineering, usual megger is as measuring equipment.Need test product to be connected between line terminal and earth terminal when insulation measurement, the insulation resistance that such measurement obtains not only comprises volume resistance but also comprise surface electrical resistance, usually the surface of sample can be received above shield terminal to avoid surface electrical resistance on the impact of result of a measurement.
2, the groundwork of leakage current test is the insulation defect problem finding to exist in cable by measuring the size of current flow through in cable test product under vdc effect.Generally, DC voltage withstand test and the leakage current test of cable insulation are carried out simultaneously, need to install suitable microampere meter in the high pressure side of test product in leakage current test.This test is almost identical with the groundwork of insulation resistance test, and difference is exactly be provided as direct supply with high-voltage rectifying device in this test, and in test, the device of indicator current is microampere meter.The insulation leakage current whether good index is the display of foundation microampere meter reflects.
3, DC voltage withstand test is the important method of traditional detection direct current cables insulation defect, its groundwork is first applied in the major insulation of cable by vdc, this vdc requires higher than the normal working voltage of cable, this voltage is kept a period of time and magnitude of voltage is as far as possible constant, if the phenomenon punctured can be there is not standing vdc high so during this period of time in tested sample of cable, then can judge that it meets the requirements, this test can find the serious defect of insulating, thus takes measures in time and avoid the generation of accident.
4, AC voltage withstand test: this test finds the defect that wherein exists and problem by detecting the insulating power of test product under ac high-voltage.If the tested cable of national regulation can bear industrial frequency experiment voltage one minute and not puncture and insulation flashover or other abnormal problems, then can judge that this cable insulation is good.
The above-mentioned laminar texture of all aluminium alloy plate not only reaches eliminates extraneous radio-frequency interference radiation completely, and vibration strength is high.
