Abstract
The utility model relates to a junction device of the wall bushing and the circular bus, which is characterized in that a grading ring is arranged inside the wall bushing and two elastic arc strip conductors in cross arrangement are provided inside the grading ring. A circular bus is provided inside the crossing area enclosed by the two elastic arc strip conductors in cross arrangement, contacting the medial of the elastic arc strip conductor. The lateral of the elastic arc strip conductor contacts the grading ring. The advantages of the utility model lies in that through the squeezing and pressing of the two elastic arc strip conductors in cross arrangement from the grading ring and the circular bus, the reliable connection of the grading ring and the circular bus through the two elastic arc strip conductors can be guaranteed. The reliable connection can ensure that the partial discharge of wall bushing can reach or less than 20pc regulated by GB and IEC. Thereby the service life of the wall bushing is extended and the operation reliability of the system is ensured.
Description
Technical field:
The utility model relates to the power transmission and distribution field, is specifically related to the jockey of a kind of wall bushing and circular bus.
Background technology:
At present the office of GB and IEC regulation wall bushing puts and is≤20pc, and when wall bushing applies in the electrical power trans mission/distribution system, innings puts the standard that just can't satisfy GB or IEC when having circular bus to run through.
Summary of the invention:
The purpose of this utility model is to provide the jockey of a kind of wall bushing and circular bus, adopts this jockey can realization office to put≤standard of 20pc.
To achieve these goals, the technical solution of the utility model is as follows: the jockey of a kind of wall bushing and circular bus, comprise wall bushing, be located at the circular bus in the wall bushing, it is characterized in that being provided with in the wall bushing grading ring, be provided with two elasticity arc plate conductors arranged in a crossed manner in the grading ring, be provided with circular bus in the intersection region that these two elasticity arc plate conductors arranged in a crossed manner surround, the interior side contacts of circular bus and elasticity arc plate conductor, the outside of elasticity arc plate conductor contacts with grading ring.One of them elasticity arc plate conductor two ends has a notch, and the two ends of another elasticity arc plate conductor are respectively equipped with projection.
Advantage of the present utility model is, by the extruding of grading ring and circular bus to two elasticity arc plate conductors arranged in a crossed manner, can guarantee that grading ring reliably is connected by two elasticity arc plate conductors with circular bus, connect reliably guaranteed wall bushing office unconventional and unrestrained to or less than the 20pc of GB and IEC regulation, prolong the useful life of wall bushing, guaranteed reliability of system operation.

Embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
The jockey of a kind of wall bushing and circular bus, comprise wall bushing 1, be located at the circular bus 4 in the wall bushing 1, it is characterized in that being provided with in the wall bushing 1 grading ring 2, be provided with two elasticity arc plate conductors 3 and 5 arranged in a crossed manner in the grading ring 2, be provided with circular bus 4 in the intersection region that these two elasticity arc plate conductors 3 and 5 arranged in a crossed manner surround, the interior side contacts of circular bus 4 and elasticity arc plate conductor 3 and 5, elasticity arc plate conductor 3 contacts with grading ring 2 with 5 the outside.The two ends of one of them elasticity arc plate conductor 3 have a notch 6, and the two ends of another elasticity arc plate conductor 5 are respectively equipped with projection 7.
A grading ring 2 is set in wall bushing 1 earlier, 2 elastomeric 2mm beryllium-bronze sheets are processed into the elasticity arc plate conductor 3 and 5 of shape shown, the projection 7 at elasticity arc plate conductor 5 two ends is penetrated respectively in the notch 6 at elasticity arc plate conductor 3 two ends, form two elasticity arc plate conductors 3 and 5 arranged in a crossed manner, circular bus 4 is penetrated in these two elasticity arc plate conductors 3 arranged in a crossed manner and 5 intersection regions that form, again circular bus 4 is penetrated in the wall bushing 1, make elasticity arc plate conductor 3 and 5 the outside contact with the inwall of grading ring 2 in being located at wall bushing 1.Rely on the high resiliency of beryllium-bronze, when these two elasticity arc plate conductors 3 can reliably be connected circular bus 4 with grading ring 2 behind the pressurized in grading ring 2 with 5, connect reliably guaranteed 1 innings of wall bushing unconventional and unrestrained to or less than the 20pc of GB and IEC regulation, prolong the useful life of wall bushing 1, guaranteed reliability of system operation.
Claims (2)
1, the jockey of a kind of wall bushing and circular bus, comprise wall bushing, be located at the circular bus in the wall bushing, it is characterized in that being provided with in the wall bushing grading ring, be provided with two elasticity arc plate conductors arranged in a crossed manner in the grading ring, be provided with circular bus in the intersection region that these two elasticity arc plate conductors arranged in a crossed manner surround, the interior side contacts of circular bus and elasticity arc plate conductor, the outside of elasticity arc plate conductor contacts with grading ring.
