Problems solved by technology

During use, if at least one of the two tube busbars deviates, it will cause a lot of pressure on the elastic contact fingers at a certain point and even cause damage to the elastic contact fingers. At this time, there is a gap between the tube busbar and the intermediate conductor. It is not conducive to the airtightness inside the pip

Example Embodiment

[0017] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0018] The specific embodiment 1 of the pipe and female connection fittings of the present invention, such as figure 1 1 is the thick tube busbar, 2 is the thin tube busbar, 3 is the contact, 4 is the spring contact finger, 5 is the aluminum terminal board, 6 is the contact seat, 7 is the limit wear-resistant slip ring, and 8 is the End capped shield.

[0019] The thin-tube busbar 2 is inserted into the thick-tube busbar 1, and one end of the thin-tube busbar 2 is located in the thick-tube busbar 1, and the two can perform relative plugging and retracting movements. The inside of the thick tube busbar 1 is provided with an aluminum terminal plate 5 away from the thin tube busbar 2. The aluminum terminal plate 5 is arranged in the radial direction of the thick tube busbar 1 and conducts with the thick tube busbar 1, and the contact 3 is installed on th...

Abstract

The invention provides a tubular busbar connection structure. The tubular busbar connection structure comprises a first tubular busbar and a second tubular busbar which are telescopically assembled. One end of the first tubular busbar is arranged in the second tubular busbar. A contact extending along the axial direction of the tubular busbar is fixedly arranged in one of the tubular busbars, and a contact finger matched with the contact is fixedly arranged in the other tubular busbar. The annulus between the first tubular busbar and the second tubular busbar is provided with a limiting structure used for preventing radial swinging of the two tubular busbars. The first tubular busbar can be inserted into the second tubular busbar and can telescopically move. The contact and the contact finger which can be conducted with the tubular busbars are correspondingly arranged in the first tubular busbar and the second tubular busbar so that constant conduction can be guaranteed in telescopic movement of the two tubular busbars. Radial swinging of the first tubular busbar and the second tubular busbar can be prevented by the limiting structure so that the situation that the certain part of the contact finger is affected by excessive pressure and damaged can be prevented. The contact and the contact finger are installed in the tubular busbars without the influence of corona.

Description

technical field [0001] The invention relates to power transmission equipment, in particular to a pipe-bus connection structure. Background technique [0002] In order to avoid unnecessary damage to the UHV project caused by special harsh environments such as earthquakes and strong winds, higher requirements are put forward for the equipment or busbar connection fittings, and the equipment or busbar connection fittings are required to have a large offset adjustment (no less than ±400mm), and the original single flexible wire connection method can no longer meet such needs, so it is necessary to design a new structure to meet the requirements of this function. When designing a new structure, directly reserving a certain length of flexible wire can meet the requirement of a large offset adjustment when the two pipe busbars slide relative to each other, but the space at the connection between the pipe busbars is limited and cannot place too many flexible wires. Moreover, the ph...
