Abstract

The invention provides a relay protection device power panel and a configuration method thereof. The relay protection device power panel and the configuration method are characterized by respectively receiving a first output signal of a power supply through two first filtering units which are connected in parallel with the power supply, then transmitting the first output signal to a transformer for voltage adjustment after being subjected to full-bridge rectification and capacitor filtering and outputting the first output signal, and finally, outputting to electric equipment after synchronous rectification or diode rectification. According to the relay protection device power panel and the configuration method thereof, the failure rate of the board card is effectively reduced through double configuration of the power board card, and the reliability of the whole device is greatly improved.

Description

technical field [0001] The invention relates to the field of power system protection and control, and more specifically, to a power board of a relay protection device and a configuration method thereof. Background technique [0002] In recent years, the CPU has the largest proportion of defects in the main body of the relay protection device, and the second is the power plug-in. With the implementation of CPU dual configuration, the defects of the CPU have been relatively greatly improved, but compared with other chips, the problem of the power plug-in has been particularly prominent in recent years. As one of the core boards of the relay protection device, its stability and reliability greatly determine the stability and reliability of the overall device, but it still has the following deficiencies: first, the failure rate of the power board remains high, and second, the power chip After localization, its performance reliability has been reduced, and its long-term operatio...
