Problems solved by technology

However, there are disadvantages in the resistance sheet used in large current resistors: the elastic modulus of the resistance sheet is small and easy to deform, and it will cause the problem of deformation of the resistance sheet after being impacted by high-voltage power for many times; The heat dissipation effect has a certain limit on its thickness, but the space required for a thin resistor sheet is large, which is not conducive to simplifying the overall volume of a high-current resistor

Description

technical field [0001] The invention relates to the technical field of large current resistors, in particular to a tubular resistor suitable for high current. Background technique [0002] During the high-voltage power system test, a high-current resistor is required to test the DC component of the limit short-circuit test current in the primary circuit of the impact generator or transformer system. Existing high-current resistors are resistance sheets formed by stamping or welding. However, there are disadvantages in the resistance sheet used in large current resistors: the elastic modulus of the resistance sheet is small and easy to deform, and it will cause the problem of deformation of the resistance sheet after being impacted by high-voltage power for many times; The heat dissipation effect has a certain limit on its thickness, but the space area required by the thin resistor sheet is large, which is not conducive to simplifying the overall volume of the high-current r...
