Coal mine power supply equipment value management software LYXK2030
The basic task of the comprehensive protection device of high and low voltage switch in coal mine power supply system is to automatically, quickly and selectively remove the faulty equipment or line from the power system, so that the faulty components will not be damaged, and ensure that other trouble-free parts will quickly return to normal operation. When the project system capacity is large and the wiring is complex, the protection configuration design and action coordination will be very difficult, and the protection selectivity and reliability problems are prominent. Therefore, it is necessary to carry out reasonable configuration, analysis and calculation of the integrated protection device and setting value of the power system. Moreover, with the increase of the system capacity and the adjustment of the system load, the setting value of the integrated protection device of the system needs regular accounting and maintenance. In order to ensure that the requirements of the actual working conditions are met.
