Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage cabinets, in particular to an anti-eddy current low-voltage switch cabinet. Background Art

[0002] With the continuous improvement of industrial automation and electrification, low-voltage switchgear, as an important component of the power system, its performance and reliability are crucial to the stable operation of the power system. However, in traditional low-voltage switchgear, when current flows in the conductor, a magnetic field is generated. When the conductors in the magnetic field move relative to each other, eddy currents are generated. Eddy currents generate heat in the conductors, resulting in energy loss and increased power system operating costs. The heat generated by eddy currents may cause the internal temperature of the switchgear to rise, shortening the normal operation life of the equipment. The electromagnetic field generated by eddy currents may interfere with the normal operation of surrounding electronic equipment, affecting their normal operation. The electromagnetic interference generated by eddy currents may also cause noise pollution in the switchgear and its surrounding environment.

[0003] In actual use, due to the complexity of the internal structure of components and the requirements of material properties, certain defects or stress concentrations may occur during the manufacturing process. These factors will reduce the mechanical strength of the components, making them prone to deformation or damage when subjected to certain loads, thus affecting the normal operation and safety of the equipment.
