Thesis: "control back to the break and the AC voltage circuit break" causes and treatment
Abstract
Based on three years of specialized study of theory and operation and inspection site internship experience, combined with the control circuit break and AC voltage circuit break in site signs, control and protection signals and related equipment failure, emergence phenomenon signals and phenomena; issued conditions and reasons; the way of the signal; specific failure location judgment and judgment in accordance with a brief analysis shows. At the same time, different phenomena of the different causes of failure, the same reasons for failure, respectively proposed the fast approach. Analysis shows that using a simple switch control schematic circuit diagram of the AC voltage, the more commonly used on-site map, and this article to correct for field staff and guidance.
Key words: control loop; AC voltage circuit; break; analytical processing
