Introduction. A simplified summary of the theory of stationary electric contactsvery unwieldly style. For example, the fundamental concept of contact surface can not be treated in detail before the constriction resistance has been defined, since determinations of the conducting areas are based on the measurement of constriction resistances. Again, the concept of the constrictioPALMY 发表于 2025-3-30 13:01:05

The contact resistance. General theorywledge by forming the definitions on a broader basis, and it is felt that a typical example may illustrate their content without limiting the range of vision. Since thermoelectric forces are irrelevant for the concepts, we neglect them in the first instance and take them into consideration later. SeRADE 发表于 2025-3-30 22:03:59

The contact surface as a function of load, elastic and plastic properties of the membersnt of principle is that the deformation which determines the load bearing area, .., usually is elastic up to pressure limits of the order of the hardness, which is defined as an average pressure in the ball indentation test under the condition that the specific depth. is > 0.02, and is called . in A肉体 发表于 2025-3-31 05:16:56
The relation between contact load and resistance, particularly at moderate and high load) provided the indentation be purely elastic. When the deformation becomes plastic, .. will correspond to Eq.

The increment is given off as heat, making the anode warmer than the cathode. A portion of the liberated heat flows back to the cathode acros懒惰人民 发表于 2025-3-31 21:14:27
