specific Embodiment 1

[0054] like figure 1 As shown, the supporting fittings for the connection between the wall bushing and the pipe busbar provided in this embodiment include a connecting supporting device, and the connecting supporting device is provided with a first connecting piece and a second connecting piece that are slidably assembled, through the first connecting piece and the second connecting piece The relative sliding between the second connecting parts can realize the relative movement between the wall bushing and the tube nut. In this embodiment, by adopting the sliding fit between the first connecting piece and the second connecting piece, it is avoided to design corresponding sliding turntables according to different pipe busbars, and the technical problem of high requirements for connecting fittings in the installation process is solved.

[0055] Specifically, if figure 1 As shown, the connection support fittings include a bushing terminal holding clip 1 and a pipe mother holding...

specific Embodiment 2

[0067] It differs from Embodiment 1 mainly in that: in Embodiment 1, the second connecting piece is a guide cylinder, and the universal connection structure is arranged between the second connecting piece and the pipe nut holding clip. In this embodiment, the universal connection structure is arranged between the first connecting piece and the clamp of the bushing terminal, which also enables relative swing between the pipe busbar and the wall-penetrating bushing.

[0068] Of course, in other embodiments, universal connection structures can also be provided between the first connecting piece and the bushing terminal holding clip, and between the second connecting piece and the pipe mother holding clip, so as to realize the connection between the pipe busbar and the through-wall The relative swing of the casing.

specific Embodiment 3

[0070] The main difference between it and Embodiment 1 is: in Embodiment 1, the first connecting part is a guide rod, the second connecting part is a guiding cylinder, and the guiding rod and the guiding cylinder are slidably supported and assembled. In this embodiment, both the first connecting piece and the second connecting piece are supporting plates, and the supporting plates are rigid parts, and one of the supporting plates is provided with a long slot hole, and the other supporting plate is provided with a round hole. When the two supporting plates When the guide is fitted, the long slot hole and the round hole are connected correspondingly, and the pin shaft is installed so that the long slot hole and the round hole are connected by the pin shaft, and the pin shaft can slide along the long slot hole. At this time, the two connecting parts can be realized The relative sliding assembly in the left and right directions, of course, in order to achieve effective support, two...

Abstract

The invention relates to a wall bushing and tubular bus connecting and supporting fitting which comprises a bushing terminal holding clamp and a tubular bus holding clamp which are arranged at an interval in the left-right direction, wherein the two holding clamps are connected through a connecting and supporting device. The bushing terminal holding clamp is conductively connected with the tubular bus holding clamp through a conductive band, the connecting and supporting device comprises a first connecting piece and a second connecting piece, and the first connecting piece and the second connecting piece are assembled together in a sliding and supporting manner and in the left-right direction and are used for achieving the relative movement of a tubular bus and a wall bushing in the left-right direction through the relative sliding of the two connecting pieces. Universal connecting structures are correspondingly arranged between the first connecting piece and the bushing terminal holding clamp and / or between the second connecting piece and the tubular bus holding clamp, so that the tubular bus and the wall bushing can swing relatively. The wall bushing and tubular bus connecting and supporting fitting provided by the invention is assembled and connected with the tubular bus through the tubular bus holding clamp, so that the design of a sliding turntable to be matched with the tubular bus is avoided, and the requirement for the connection fitting is reduced.

Description

technical field [0001] The invention relates to a support fitting for connecting a wall-through bushing and a pipe busbar. Background technique [0002] In the valve hall of the converter station, the connection support fittings are often used to connect the wall bushing and the busbar. The connection support fittings can realize the support connection between the wall and the busbar. At the same time, it also has a conductive belt for the wall bushing. The conductive connection with the pipe busbar, and the conductive belt is more redundant, and the conductive connection is still guaranteed when the pipe busbar moves relative to the wall bushing. The structure of this type of fittings is such as the connection and support fittings between the 800KV wall bushing and the current transformer provided in the Chinese invention patent with the application publication number CN103915799A. The connection support fittings include a rotating connection device. One end of one end is ...
