Description

Bus-bar clamp bracket

Technical Field

The utility model relates to a bus-bar clamp bracket.

Background

Cables, wires and copper bars are the most used components in electrical products, and the current in the grid is much greater than the current value of domestic appliances. A magnetic field is generated around the conductors due to the generation of the current, and attraction or repulsion between the wires occurs due to the lorentz force.

In addition, the cable can be found to have different cross-sectional areas in the use process, and the different cross-sectional areas are different due to the different resistances of the cables in unit length, so that the heating value of the cables in unit volume is different, and in order to prevent fire, the related national standards use cables with different cross-sections for different currents.

Because of the generation of electromagnetic force and the consideration of temperature, the electric force and structural deformation of the copper bar are required to be considered in the design of electric network equipment such as an electric cabinet and the like, and the temperature rise of the copper bar meets the requirements of national standards.

According to practical situations, the instantaneous value of the short-circuit current is far greater than the rated current value of the copper bar, so that the copper bar needs to be fixed at a proper position in the electrical equipment to reduce the stress value. And the busbar is a key electric energy carrier of the electric power transmission and distribution system and carries the quality and safety of electric energy distribution.
