The utility model has the advantages of low discharge coefficients and stable quality. The utility model conforms the national standard.
Description
The utility model relates to transformer, the light-duty partial discharge-free test transformer of particularly a kind of gas-filled type.
Before the utility model proposes, Patent Office of the People's Republic of China once disclosed a kind of name and had been called the light-duty testing transformer ＂ of ＂ gas-filled type, and the patent No. is 92220904.9 utility model patent.This patent is because the problem on the structural design causes the transformer discharge coefficient to surpass PC, disqualification rate height.As on the cover plate of device body, protruding part being arranged, make and easily produce corona between high-voltage output end outside and the ground; Link to each other with spring thimble between conducting rod and the line bag,, cause loose contact, even occur opening circuit easily in transportation or be subjected to be shifted under the earthquake situations condition.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of rational in infrastructurely, can reduce discharge coefficient, the light-duty partial discharge-free test transformer of stay-in-grade gas-filled type.
At the foregoing invention purpose, the utility model adopts following technical scheme: the light-duty partial discharge-free test transformer of a kind of gas-filled type, mainly by conducting rod 11, be enclosed within the sleeve pipe 8 of conducting rod 11 outsides, device body 5, line bag 1 and iron core 2 and voltage equalizing ball 9 are formed, wherein, be full of in this transformer dielectric SF6 gas is arranged, the lower end of conducting rod 11 contacts with line bag 15, special character of the present utility model is that the cover plate 7 of described device body 5 adopts spherical dished cover, described line bag 1 is by the spheroidal coiling, between described conducting rod 11 and the line bag 1 logical peraluminous hollow in voltage equalizing ball 3 link to each other, the height of online bag 1, the screen 16 that adds a ground connection between the low-voltage coil, the two ends of online bag 1 are added with inner shield baffle plate 4, and the input terminal of this transformer and charge valve parts all are installed on the device body 5.
Structure of the present utility model is tending to be reasonable more, it gives full play to the high advantage of SF6 gas-insulated performance, reduced discharge coefficient at many levels, interior voltage equalizing ball especially is set between high-voltage line bag and conducting rod, improved the field strength distribution of conducting rod and high-voltage line bag, reduced the generation of the inner corona of transformer, made the high pressure output solid and reliable, can loose contact that exists in the background technology even the fault that opens circuit have not thoroughly been eliminated because of vibrations are shifted.This transformer is in light weight, and electric property is stable, reliable in quality, and corona is minimum, and its every technical indicator can reach relative national standards fully.
Below in conjunction with the accompanying drawing illustrated embodiment, describe the utility model in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is an I place partial enlarged drawing among Fig. 1.
Fig. 3 is an A-A cutaway view among Fig. 1.
Fig. 4 is the front view of inner shield baffle plate 4.
Fig. 5 is the left view of Fig. 4.
The utility model mainly is made up of line bag 1, iron core 2, device body 5, sleeve pipe 8 and conducting rod 11 and voltage equalizing ball 9, sees Fig. 1.Leave certain clearance between conducting rod 11 and sleeve pipe 8 inwalls.Be filled with 4.5-5Kg/cm in this transformer
2Dielectric SF6 gas.The aluminium matter inner shield baffle plate 4 of ground connection is equipped with at online bag 1 two ends, sees Fig. 4 and Fig. 5, can make the field intensity at line bag both ends even.Between the high-low pressure of coiling line bag, add screen 16 ground connection that a copper sheet is made, see Fig. 3, make between the high and low pressure and isolate, do not produce corona.Line bag 1 is by the spheroidal coiling, and interlayer adopts 0.05mm high-strength polyester film as main insulation, and outermost layer is with whole one week of copper sheet coiling.The top of conducting rod 11 is provided with dried mushroom shape voltage equalizing ball 9, and high-voltage output end 10 is positioned at the bottom of voltage equalizing ball 9, can not cause the tip apex discharge.Conducting rod 11 lower ends are contained in the screw of hollow interior voltage equalizing ball 3 upper ends of aluminium matter, and interior voltage equalizing ball 3 lower ends are tightened on the standing screw 17 that is positioned at line bag 1 upper end, make firm and reliable connection, and reduce the corona generation.The cover plate 7 of device body 5 adopts spherical dished cover, meets pressure vessel code.The input terminal 13 and the charge valve parts 6 of this transformer all are installed on the sidewall of device body 5, make decannulation 8 outer no any projecting member on the cover plate 7, thereby can reduce the corona that produces between high-voltage output end outside and the ground.Whole ＂ O ＂ shape sealing ring 12 is all adopted at all sealing positions that needs of this transformer, adds stop-leak compound and uses bolted.In Fig. 1, piece number 14 is supports, the 15th, and wedge.
