Description

Technical Field

[0001] The utility model relates to the technical field of electric power automation, and particularly relates to a connecting copper bar for a high-voltage switch cabinet. Background Art

[0002] Grounding is an electrical safety measure taken to ensure the normal operation of electrical equipment and personal safety. It is achieved by connecting a metal wire to a grounding device. Commonly used grounding methods include protective grounding, working grounding, lightning protection grounding, shielding grounding, anti-static grounding, etc. The grounding device introduces leakage current, static charge, lightning current, etc. that may be generated on electrical equipment and other production equipment into the ground, thereby avoiding personal electric shock and possible accidents such as fires and explosions. In the power system, to prevent electric shock or protect the safety of equipment, the metal chassis or shell of electrical and telecommunications equipment is connected, and the ground wire uses the earth as a current return path. In the power system, it is also called grounding to make a good electrical connection between the neutral point, shell or support of equipment and electrical devices and the grounding device with a conductor. In addition to guiding some useless current or noise interference into the ground, the greatest function of grounding is to protect users from electric shock.

[0003] To facilitate equipment grounding, a grounding copper bar is generally set as a wire gathering point for circuits, equipment, etc., and then grounded uniformly through the grounding copper bar. The copper bar, also known as the copper busbar or copper bus, is made of copper and is a long conductor with a rectangular or chamfered rectangular cross-section, which plays the role of transporting current and connecting electrical equipment in the circuit. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connecting copper bar for a high-voltage switch cabinet provided with a cooling structure.

[0005] The technical solution of the utility model is: a connecting copper bar for a high-voltage switch cabinet, including a connecting copper bar body, on which fixing holes for fixed connection and cooling holes for cooling are provided.

[0006] In a further technical solution, the connecting copper bar body is arranged in an L shape, including a connecting part for installing wire harnesses and a fixing part for fixing positions, and fixing holes are provided on both the connecting part and the fixing part.

[0007] In a further technical solution, a group of cooling holes is arranged on the connecting part on one side of the fixing hole.

[0008] In a further technical solution, chamfers are provided at the free ends of the connecting part and the fixing part.

[0009] In a further technical solution, each group of cooling holes is provided with 2 - 6.

[0010] The beneficial effects of the utility model:

[0011] The structure of the utility model is simple. By adding cooling holes on the connecting part for installing wire harnesses, heat dissipation is carried out through the cooling holes, avoiding overheating of the wire harnesses at this place, and improving the safety and reliability of the use of the connecting copper bars in the switch cabinet. Moreover, the connecting part and the fixing part are arranged in an L shape, ensuring that the wire harness fixing and the equipment fixing are on different planes, thus facilitating the installation of the connecting copper bars. Through the setting of the cooling holes and chamfers, the materials in the production process of the connecting copper bars are reduced, with high economic benefits and suitable for popularization and use.
