How to Predict Life Span of the Switchgear?

Load and Number of Switching CyclesProspective Service LifeMechanical Life SpanElectrical Life SpanAssessment of The ContactsThe life span of switchgear basically depends on the size of the load and the number of switching cycles. Instead of a time span, with electromechanical switchgear reference is usually made to the number of operations, as the ageing mainly depends on the stress during switching and less on the on- and off-phases between. The maximum number of operations is determined by the wear of heavily loaded components in: 1. Contactors, 2. Load switches and 3. Circuit breakers especially of the contact system. For switchgear, the mechanical and electrical life spansare separately defined. The mechanical life span states the number of possible operations without electrical loading, while the electrical life span states the number of operations for a certain size of electrical loading and a certain utilization category. In electronic devices, the life span is usually less dependent on the number of operations but rather on the working temperature. Thus for example electrolytic capacitors (for ex...Get price
