The utility model is characterized in that a voltage-sharing ball (6) is hung on a lower porcelain flange A (5); the inside of the voltage-sharing ball (6) is provided with a connecting flange B (8); the connecting flange B (8) is symmetrically provided with a dumbbell-shaped locking hole C (9); the lower surface of a lower porcelain flange A is provided with a plurality of semi screw holes D (10); the interval of the lower porcelain flange A (5) and the connecting flange B (8) is provided with a spacing screw (12); the back end of the spacing screw (12) is fixedly connected with the lower porcelain flange A (5) by the semi screw hole D (10). The utility model can be used for the field of transformers.
Description
The utility model belongs to transformer accessory field, particularly a kind of current-carrying formula oilpaper capacitance graded bushing.
Sleeve pipe is the significant components on the electric equipment products.As the lead-out wire sleeve pipe, basic employing is the cable formula of the wearing sleeve pipe of continuity for many years on transformer.
Utilize the copper pipe in the middle of the sleeve pipe fuse, the cable of lifting one's head of transformer coil is passed from copper pipe, is connected the energy delivery and the change in voltage of realization transformer with electrical network.The frame mode of this transformer outlet is all adopting both at home and abroad.There are a lot of shortcomings in this outlet method in manufacturing, installation, operation, particularly on-the-spot suspended core etc.
1, transformer copper cable lead-out wire, when drawing in the middle of the copper pipe of tube core, pigtail splice that is to say that with army cap is screwed in cable and copper pipe are equipotential, but finding has electric discharge phenomena between cable and the copper pipe, circulation is also arranged, and the result produces gases such as acetylene, and this gas dissolving is in transformer oil, cause the chromatogram existing problems of transformer oil, to the chromatogram of operational monitoring transformer oil, judge that whether transformer itself has fault, brings difficulty.
2, transformer copper cable lead-out wire, the root that goes between in operation very easily bends, and the lead-in wire that shields is caused damage, puts the problem of bringing for product office.
3, wear in the assembling of cable formula oilpaper capacitance graded bushing, personnel will climb, and there are many problems in processing safety.
The purpose of this utility model is to provide a kind of simple in structure, easy for installation, reliable in quality, fail safe good, and can accurately monitor the current-carrying formula oilpaper capacitance graded bushing of judging the transformer running status.
Technical solution of the present utility model can realize according to following mode:
A kind of current-carrying formula oilpaper capacitance graded bushing contains: oil conservator, last porcelain spare, spacer flanger, lower ceramic part, lower ceramic part flange A, middle part copper pipe; It is characterized in that: on described lower ceramic part flange A, hang with the voltage equalizing ball that wiring hole is joined in the bottom; In described voltage equalizing ball, laterally is furnished with connecting flange B; Described middle part copper pipe vertically passes the mesopore of connecting flange B; On described connecting flange B, is furnished with several dumb-bell shape lock holes C with its center symmetry that is as the criterion; Several half screws D is attacked in position at the corresponding dumb-bell shape lock hole of described lower ceramic part flange A lower surface C; Between described lower ceramic part flange A and connecting flange B, is furnished with stop screw by dumb-bell shape lock hole C; The end of stop screw is fixedly connected through half screw D and lower ceramic part flange A; One in the aperture at described dumb-bell shape lock hole C two ends greater than another then less than the Forward End Cap of stop screw; On described screw, be with spring, connecting flange pad.
The quantity of dumb-bell shape lock hole C described in the utility model can be 3.Voltage equalizing ball can be apple shape.Copper pipe two ends, described middle part are shrunk to terminals.
The utility model is simple in structure, reliable in quality, fail safe are good, failure rate is low and can accurately monitor and judge the transformer running status.
Below in conjunction with accompanying drawing in detail preferred forms of the present utility model is described in detail:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the utility model connecting flange structural representation
Fig. 3 is the utility model middle part copper pipe structural representation
As shown in the figure, this product is middle part copper pipe 7 conductions of utilizing in the middle of the sleeve pipe fuse, the cancellation leader cable, with transformer coil lift one's head the bit copper skin, be connected to the tail wiring end 15 of sleeve pipe, middle part copper pipe 7 tops directly and electrical network join.It contains: oil conservator 1, last porcelain spare 2, spacer flanger 3, lower ceramic part 4, lower ceramic part flange A5 middle part copper pipe 7; It is characterized in that: on described lower ceramic part flange A5, hang with the voltage equalizing ball 6 that wiring hole 11 is joined in the bottom; In described voltage equalizing ball 6, laterally is furnished with connecting flange B8; Described middle part copper pipe 7 vertically passes the mesopore of connecting flange B8; On described connecting flange B8, is furnished with several dumb-bell shape lock holes C9 with its center symmetry that is as the criterion; Several half screws D10 is attacked in position at the corresponding dumb-bell shape lock hole of described lower ceramic part flange A5 lower surface C9; Between described lower ceramic part flange A5 and connecting flange B8, is furnished with stop screw 12 by dumb-bell shape lock hole C9; The end of stop screw 12 is fixedly connected through half screw D10 and lower ceramic part flange A5; One in the aperture at described dumb-bell shape lock hole C9 two ends greater than another then less than the Forward End Cap of stop screw 12; On stop screw 12, be with spring 13, connecting flange pad 14.The quantity of dumb-bell shape lock hole C9 can be 3.Voltage equalizing ball 6 is an apple shape.3 of half screws are attacked in the position in garden week 120 on lower ceramic part flange A5 lower surface.Stop screw 12 is fixedly connected by half screw D10 and lower ceramic part flange A5, and the diameter of connecting flange pad 14 is greater than the aperture of dumb-bell shape lock hole C9.Voltage equalizing ball 6 and lower ceramic part 4 separated attitudes when mounted, after transformer lead joins by wiring hole 11 and terminals 15, the voltage equalizing ball 6 that moves up and have connecting flange B8, the dumb-bell shape lock hole C9 on the connecting flange B8 is by turning an angle voltage equalizing ball 6 lockings.Can be furnished with the lock slots 16 that conforms to stop screw 12 Forward End Cap sizes respectively at the aperture place of described lock hole C9.Stop screw 12 just can not gone here and there the large aperture end of lock hole C9 when transformer is worked like this, may cause coming off of voltage equalizing ball 6 therefrom.
