Redundant power system

Abstract

The invention provides a redundant power supply system, which comprises a first power supply module and a second power supply module, wherein the first power supply module and the second power supply module are mutually redundant; the first power supply module comprises a first power supply circuit; an input end of the first power supply circuit is provided with a first input control indicating circuit; an output end of the first power supply circuit is provided with a first output control indicating circuit; the second power supply module comprises a second power supply circuit; the input end of the second power supply circuit is provided with a second input control indicating circuit; and then output end of the second power supply circuit is provided with a second output control indicating circuit. The redundant power supply system can accurately carry out displaying and alarming on a broken power supply when the power supply is broken down, can timely inform a worker to repair and can automatically finish switching of redundant power supplies in the fault process, so that the condition that the overall power supply system can lastingly and stably supply electricity to a load is ensured.

Description

technical field [0001] The invention relates to a power supply system, in particular to a redundant power supply system. Background technique [0002] In the current power supply of industrial equipment, in order to ensure the continuous stability of load power consumption, the power supply is often equipped with two power supplies, and the power supplies are mutually redundant. For example, in the security door system of the rail transit platform, the existing In a redundant power supply system, two power supplies are generally used in parallel to form redundancy. However, this structure has the following defects: when a failure occurs during the power supply process, and when the power supply cabinet of the power system is working normally, the maintenance personnel cannot accurately judge the power supply. Faults in the system can only be detected when the power supply cabinet is undervoltage or out of power, which seriously affects the continuous and stable power supply ...
