Problems solved by technology

During the construction, not only cable trenches, cable tunnels and other facilities need to be built, but the cost of civil engineering is high, the construction period is long, and it is easy to be damaged by water, fire, rats and external forces. Rework caused by accidents will greatly increase the project cost

Embodiment approach

[0030] Implementation method: fix the fixed bracket 4 on the tunnel wall, and adjust the upper end of the busbar bracket 1 by rotating the bracket 5 along the arc groove on the fixed bracket 4. The two ends of the tubular busbar 2 are connected by bellows joints 10 to form a power supply trunk. The branch line 8 is connected to the load 9 to realize fast and safe power taking from the branch line.

[0031] The pipe-female system is a rigid system, and the connection must be firm, and the connection contact surface must be reliable, but it is inconvenient to fine-tune according to the installation environment. Outdoor operation is affected by thermal expansion and contraction due to weather, which will cause damage to the pipe-female connection. The present invention adopts stretchable and bendable corrugated pipes as adjustment parts, which can be easily adjusted at installation dislocations and small bends. One adjustment part is added every other section, and the influence o...

Abstract

The invention discloses a tubular-busbar low-voltage power transmission system, and the system comprises a busbar support, a tubular busbar and an electricity taking device, wherein the upper end of the busbar support is horizontally provided with quick installation pipe hoops in a parallel and fixed manner. The tubular busbars are respectively clamped in the quick installation pipe hoops, and theelectricity taking device is disposed at the peripheries of the tubular busbars. The ends of the tubular busbars are connected in a sleeved manner through corrugated pipe joints, and are fixed through the pipe hoops. Moreover, the external surfaces of the corrugated pipe joints are coated with insulating layers. The tubular busbars are employed as transmission lines, so the system is high in mechanical strength, is large in current-carrying capacity, is low in loss, is high in reliability, is strong in capability of resisting environmental interference, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power transmission, and in particular relates to a tubular busbar low-voltage power transmission system. Background technique [0002] At present, the low-voltage AC transmission system mainly uses cables for power supply. Due to the large capacitance of cables, a large capacitor charging current will be generated when transmitting AC power, which not only increases line loss, but also reduces line transmission capacity. During the construction, not only cable trenches, cable tunnels and other facilities need to be built, but the cost of civil engineering is high, the construction period is long, and it is easy to be damaged by water, fire, rats and external forces. The rework caused by the accident will greatly increase the project cost. Contents of the invention [0003] The invention provides a tubular busbar low-voltage power transmission system to overcome the deficiencies in the prior...
