N2 - For the circuit is getting more and more complex, the requirements for higher overload capacity of the relay is rising. The experiments for a small hermetically sealed relay (SHSR) based on IEC standard is carried out, the image of breaking arc and dynamic characteristic of the SHSR is analyzed. For the disadvantages of operating voltage rising and anti-vibration performance decreasing, traditional force-velocity design method needs to be improved. To overcome these shortcomings, a novel break kinetic energy-based method is presented in this paper to improve the overload capacity of SHSR. The break kinetic energy model (BKEM) is established. An improved structure of the spring and the contact system of the relay is introduced according to BKEM. The FEM model for electromagnetic system and the dynamic model for contact system are established. The improved design is simulated, therefore carry out the comprehensive improvement of the resisting surge capacity. Overload tests are carried out to test the BKEM based design method. The validity of the BKEM for resisting surge performance has been verified comparing with the original design of the SHSR.
