Description

Technical Field

[0001] The present invention relates to the technical field of power transmission, and particularly to a visual low-voltage busbar connector and its application. Background Art

[0002] Due to the advantages of intensive space and large transmission capacity of the low-voltage busbar, the form of the low-voltage busbar is widely used for power transmission. The low-voltage busbar connector, as a component connecting different low-voltage busbars or a low-voltage busbar and other electrical equipment, is of great significance for ensuring the smooth transportation of electric energy.

[0003] However, the existing low-voltage busbar connectors are not visible, resulting in the inability to effectively monitor them during the installation process, acceptance inspection, and operation status. For example, during the installation process, if the installation is not carried out according to the standard requirements, the connector may not be correctly connected to the low-voltage busbar, resulting in loose connection or poor contact; during installation, if impurities are sandwiched between the copper sheets, the effective contact area between the copper sheets will be reduced, and more heat will be generated when the current passes through, affecting the normal operation of the busbar. During the acceptance inspection, the low-voltage busbar connector is usually in a concealed position, and it is impossible to directly observe its internal situation for acceptance work, which may lay a potential fault hidden danger for subsequent operation. After the low-voltage busbar connector is put into operation, since the operation status of the connector, such as whether there is overheating, loosening, etc., cannot be understood in real time, it is difficult to discover potential safety hazards in a timely manner.

[0045] Further, two conductors are installed between every two adjacent insulating partitions, and the two conductors are respectively installed on the side walls of the corresponding insulating partitions. The gap between the two conductors is used to fix and clamp the busbar.
