" State Grid Corporation of China's electric power safety working regulation (power transformation part) " annex J managing security tools and instruments pilot project, cycle and requirement define electroscope, ground wire, insulating bar power frequency withstand test standard are as shown in table 1.
Table 1 electroscope, ground wire, insulating bar power frequency withstand test standard
For 110kV and 220kV insulating bar, trial voltage is very high, and site test is often difficult to reach its electric pressure requirement, usually adopts the method for Sectional Test.According to regulatory requirements, 220kV can divide at most 4 sections to be tested, and trial voltage is that 132kV/0.525m, 110kV can divide 3 sections to test, and trial voltage is 88kV/0.433m, and therefore, during insulating bar test, the ceiling voltage applied is 132kV.In prior art, be difficult to accomplish use compact and the device warranty test be easy to carry to transformer station time keep enough safe distances over the ground.
Utility model content
In order to solve deficiency of the prior art and defect, the utility model aims to provide a kind of insulating bar jacking gear.This purpose of the present utility model is achieved through the following technical solutions:
A kind of insulating bar jacking gear, comprise: bar in insulation, metal outer cylinder and elevating lever register pin, in described insulation, bar is flexible in described metal outer cylinder, by the described elevating lever register pin be arranged on described metal outer cylinder, bar in described insulation is positioned at differing heights.
Further, in described insulation, bar is fiberglass pole.
Further, the long 1.1m of bar in described insulation, diameter is 20mm.
Further, described metal outer cylinder is stainless-steel tube.
Further, the long 0.9m of described metal outer cylinder, diameter is 25mm, and internal diameter is 22mm.
Further, described elevating lever register pin is spring sheet-holder.
Further, the diameter of described spring sheet-holder is 8mm, and long is 60mm.
Insulating bar jacking gear of the present utility model can be fixed on Portable insulation managing security tools and instruments KV power frequency withstand voltage test trolley, and two insulating bar jacking gears use simultaneously, one of them is fixed on the side of described test cart, be provided with pulley bottom another to slide on described test cart, regulate the insulating bar length needed for different tests.
When not test (N.T.), in described insulation, bar is contracted in described metal outer cylinder, reduces the volume of described insulating bar jacking gear with this, is convenient to carrying or places.During test, bar in insulation is pulled out in metal outer cylinder, is adjusted to the safe distance of needs according to different tests, with elevating lever register pin location, test.
By insulating bar jacking gear described in the utility model, safe distance over the ground when both having met test, can realize again the little portable object of volume.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the insulating bar jacking gear be fixed on Portable insulation managing security tools and instruments KV power frequency withstand voltage test trolley of the present utility model;
Fig. 2 is another schematic diagram of the insulating bar jacking gear be fixed on Portable insulation managing security tools and instruments KV power frequency withstand voltage test trolley of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, insulating bar jacking gear 6 of the present utility model comprises bar 62 in insulation, metal outer cylinder 61 and elevating lever register pin 63, in described insulation, in insulation described in bar 62, bar is long 1.1m, diameter is the fiberglass pole of 20mm, and it is flexible in described metal outer cylinder 61, and described metal outer cylinder is long 0.9m, external diameter 25mm, the stainless-steel tube of internal diameter 22mm.By the described elevating lever register pin 63 be arranged on outside described metal outer cylinder 61, bar 62 in described insulation is positioned at differing heights.Described elevating lever register pin is diameter is 8mm, the long spring sheet-holder for 60mm.
On the dolly skeleton 1 of described insulating bar jacking gear 6 fixed portable insulating safety tools KV power frequency withstand voltage test trolley.During not test (N.T.), in the insulation of insulating bar jacking gear of the present utility model, bar 62 takes in described metal outer cylinder 61, and its height is suitable with the height of Portable insulation managing security tools and instruments industrial frequency experiment dolly like this, the volume not outside occupying volume, convenient in carrying.The use of the utility model insulating bar jacking gear is described with insulating bar power frequency withstand test below.
Test tools: the insulating bar of existing common 110kV electric pressure, insulating bar jacking gear 6 and be fixed on the insulating bar stationary installation 7 at described insulating bar jacking gear 6 top.
Test prepares: passed successively by insulating bar in the central aperture of the insulating sleeve of insulating bar stationary installation 7, and fixed by described insulating bar by fastening screw.Arc contact chip in described insulating bar stationary installation 7 contacts to increase and the surface of contact of insulating bar with insulating bar, and doublely does pressure electrode and ground electrode.Described insulating bar stationary installation 7 is fixed on the top of bar in described insulation.
Test: for the insulating bar of the 110kV electric pressure adopted in this test, adopt point 3 sections of modes of carrying out.Therefore according to trial voltage and the two interelectrode distances of table 2 regulation, the trial voltage/length of this test is 88kV/0.433m.Mobile slidably insulating bar jacking gear 6 to 0.433m locates (the 110kV mark in alignment test length scales), and is fixed.And described insulating bar jacking gear is adjusted to the safe distance on distance ground, be then located by elevating lever register pin.External high pressure, ground connection are connected with the fastening screw 73 of two insulating bar stationary installations 7 respectively by lead-in wire, thus form test loop, start test.Slow boosted voltage, reaches 0.75 times of trial voltage value and 66kV magnitude of voltage rises, and with the rate of pressure rise of 2% trial voltage per second to trial voltage 88kV, keeps 1min, then rapid depressurization, but does not cut off suddenly.After off-test, by insulating bar jacking gear 6, tested insulating bar is reduced to operating position, loosen fastening screw 72, regulate tested insulating bar to not test (N.T.) part vertically, screw fastening screw 72, again rise to testing position and test, so in triplicate, extremely all test sections all complete.If insulating bar flashover does not occur or punctures in test, insulating bar discharge off, burn marks after test, do not generate heat, then test is passed through.Otherwise insulating bar can not use.So far insulating bar power frequency withstand test is completed.
The pilot project of table 2 insulating bar, cycle and requirement
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, the utility model is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the utility model claim.
