摘要
电磁继电器触簧系统的接点动程是影响其电接触状态和电寿命的重要参数。以典型的推杆式常开触点组为例,提出了一种接点动程的通用计算方法和测量方法,并进一步地研究了推杆水平超行程与接点动程、接触压力和接触电阻的关系。所得的结论对于电磁继电器电接触失效的分析具有实用价值。
The contact sliding distance of electromagnetic relay＇s spring system is an important parameter affecting the electrical contact state and electrical life. By taking a normally open contact with pushing rod as an example, this paper presented a general calculation and measurement method for the contact sliding distance, and further studied the relationship between the horizontal over-travel of pushing rod and the contact sliding distance, contact force and contact resistance. The conclusions have practical value for analyzing electrical contact failure of electromagnetic relay.
