Description

technical field [0001] The invention relates to a test device, in particular to the technical field of relay life test. Background technique [0002] The development direction of "spacecraft grade, high reliability" puts forward higher requirements on the reliability index of electromagnetic relays. Among them, the balanced force cubic inch electromagnetic relay is widely used in equipment, jet aircraft and other military equipment due to its excellent load on-off capability and anti-vibration performance. However, the current design and optimization stage of electromagnetic relays still lacks a sound theoretical foundation, the influence of the lower design parameters of the relay on the output characteristics, and the ablation of the contact material caused by the arc discharge between the contacts during the operation of the relay and the damage of the relay. The mechanism of degradation of operating characteristics until life failure is still unclear, which makes it dif...
