基于数字样机模型的平衡力式继电器电寿命提升
Electrical Life Improvement of Balanced Force Relay Based on Digital Prototype Model
摘要
Abstract
Aiming to address poor consistency and short electrical life of a 1/2 in3 balanced force relay of a manufacturer,research on improving the electrical life of balanced force relays is conducted.Firstly,the failure mechanism of products with electrical life failure is analyzed,and the root cause of relay life termination is determined through the analysis of arcing time,action process and suction-reaction force matching.Then,a digital prototype of the relay is established to realize the static characteristic simulation of suction and reaction force;on this basis,the key parameters of the electromagnetic system and contact spring system are optimized to achieve good suction-reaction force matching.Finally,high-temperature electrical life tests are conducted on the optimized relay prototypes.The test results show that the electrical life of the optimized products is effectively improved,and the optimization goal is achieved.关键词
