Insulated tubular bus-bar

Abstract

The invention discloses an insulated tubular bus-bar, which comprises three tubular bus-bars arranged in parallel. The three tubular bus-bars are connected by several tubular hoops. Each tubular hoopincludes a base frame and several upper pressure plates. One end of each upper pressure plate is connected with the corresponding base frame, and a gap matched with a buckle is arranged at the other end of each upper pressure plate. Each buckle is connected with a rotary pin. Each base frame is provided with counter bores matched with the rotary pins. The bottom end of each rotary pin is connectedwith the corresponding base frame through a locking spring. Through the cooperation of the buckles, the upper pressure plates and the base frames, the installation time is greatly saved compared withthe traditional thread locking method. Moreover, during locking, the locking springs always provide a downward locking force for the corresponding upper pressure plates to ensure that there is no gapbetween each upper pressure plate and the corresponding base frame.

Description

technical field [0001] The invention relates to an insulating tubular busbar. 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. [0003] As an alternative to cables, insulated tubular busbars are becoming more and more popular with consumers due to their excellent electrical performance. Insulated tubular busbars are generally three busbars arranged side by side, and the three busbars need t...

[0003] As an alternative to cables, insulated tubular busbars are becoming more and more popular with consumers due to their excellent electrical performance. Insulated tubular busbars are generally three busbars arranged side by side, and the three busbars need to be separated by a certain distance. The hoop connects the three busbars, but the existing pipe hoops are usually connected by threads. After a long time of use, rust stains between the threads are difficult to disassemble, and the installation speed of the threads is slow. Taking the 3km-long tubular busbar as an example, every It takes 600 pipe clamps to set up a pipe clamp of 5m. If the installation time of each pipe clamp can be saved by 2 minutes, the installation time of 1200 minutes can be saved.
