Novel bus duct tapping device

Abstract

The invention relates to a novel bus duct tapping device, which comprises a bus duct shell, a first connecting copper bar and a second connecting copper bar, wherein a main busbar is arranged in the bus duct shell; a first mounting groove and a second mounting groove are formed in two sides of the main busbar respectively; each of the first connecting copper bar and the second connecting copper bar comprises a primary plate and a secondary plate; one side of the primary plate is connected with the secondary plate and the other side is provided with a first bolt and a second bolt; a first protective plate is arranged outside the first connecting copper bar; a second protective plate is arranged outside the second connecting copper bar; and a protective cover board is arranged between the first protective plate and the second protective plate. The novel bus duct tapping device does not need to weld; the rated working current is not reduced; the security protection performance is high; and normal power taking of a jack box of which the heavy current is greater than 630A can be facilitated.

Description

technical field [0001] The invention relates to a novel bus duct tapping device, which belongs to the technical field of electrical connectors. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multi-channel cables has brought a lot of inconvenience to the on-site installation and construction connection. As a new type of power distribution wire, the plug-in busway has emerged. Its superiority, at the same time, due to the use of new technology and new technology, the contact resistance and temperature rise of the connection at the two ends of the bus duct and the connection of the branch port are greatly reduced, and high-quality insulation i...

[0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multi-channel cables has brought a lot of inconvenience to the on-site installation and construction connection. As a new type of power distribution wire, the plug-in busway has emerged. Its superiority, at the same time, due to the use of new technology and new technology, the contact resistance and temperature rise of the connection at the two ends of the bus duct and the connection of the branch port are greatly reduced, and high-quality insulation is used in the bus duct materials, thereby improving the safety and reliability of the bus duct, and making the whole system more perfect. However, the bus duct tap-off device in the prior art generally adopts the welding method, which leads to a decrease in rated operating current and a decrease in safety protection performance, and is not suitable for current connection. The subrack takes power normally
