Abstract

The invention relates to a busbar joint protection box and a busbar connection structure. The protection box comprises an upper box body and a lower box body, and the upper and lower box bodies are connected through a connection surface at the edges of the upper and lower box bodies. The upper and lower box bodies are respectively provided with an upper flange and a lower flange in a direction departing from the connection surface, and the upper and lower flanges are bent in opposite directions to form a through cavity for accommodating a busbar joint. The upper and lower box bodies form the through cavity in a mode of flange bending, thereby reducing the workload during the connection through a bolt. Moreover, the overlapping mode also enables the formed box body to be wrapped by two insulating material layers, thereby solving a problem of poor insulating performance in a better way.

Description

technical field [0001] The invention relates to a power device protection box, in particular to a busbar joint protection box and a busbar connection structure. Background technique [0002] Busbar is an essential electrical component in medium, high and low voltage substations and high and low voltage switchgears. In order to prevent acid, alkali, salt and other chemical substances from corroding the busbar and short-circuit faults caused by small animals such as rats and snakes, and to prevent maintenance personnel from accidentally entering the charged gap and causing accidental damage, the busbar joints need to be protected by insulating materials. box for wrapping. For example, the Chinese invention patent with the authorized announcement number CN204809802U and the authorized announcement date of 2015.11.25 discloses a new type of busbar structure protection box. The protective box includes an upper box body and a lower box body, and the upper box body is opposite to ...
