Description

Electric appliance cabinet grounding copper bar optimizing connection structure Technical Field The utility model relates to the technical field of electric cabinet grounding copper bars, in particular to an optimized connection structure of an electric cabinet grounding copper bar. Background The electrical control cabinet is characterized in that the switch equipment, the measuring instrument, the protection electrical appliance and the auxiliary equipment are assembled in or on the closed or semi-closed metal cabinet according to the electrical wiring requirement, the arrangement of the electrical control cabinet meets the requirement of normal operation of an electric power system, the electrical control cabinet is convenient to overhaul, and the safety of personnel and surrounding equipment is not endangered. During normal operation, the circuit can be switched on or off by means of a manual or automatic switch, and the electric control cabinet is generally provided with a grounding copper bar, so that the effect of circuit connection is achieved. At present, the common electrical cabinet grounding copper bar connection structure adopts copper bars with fixed length, and is connected with equipment in the electrical cabinet and an external grounding system in a bolt connection, welding and other modes. However, fixed length grounded copper bars have limitations. In actual production and installation processes, electrical cabinets of different specifications and models and equipment layout in the cabinets are different, and the lengths of the grounding copper bars required are different.
