Power supply power loop control monitoring system

Abstract

The invention relates to a power supply dynamic loop controlling and monitoring system. Three 400 Hz and 220 V outer input three-phase alternating-current power sources are transferred to electric equipment in four modes through a power supply dynamic loop system. The outer input power sources of outer intermediate-frequency power generation devices are rectified to provide a 27 V direct-current power source for the system, and meanwhile three-phase power source indexes of the system and indexes of rectified direct-current voltage are monitored. The power supply dynamic loop controlling and monitoring system is suitable for short-range or long-range ceaseless power supply transferring control of the multiple intermediate-frequency power generation devices, can control power supply control and the power supply working state of any kind of intermediate-frequency power generation device in a short range or long range in an interlocked mode and meanwhile can cut off control of the intermediate-frequency power generation device with power supply failing. Finally, failure indication of the intermediate-frequency power generation devices is displayed through a display device, and meanwhile the system can measure alternating-current voltage values and frequency values of the outer intermediate-frequency power generation devices and measure a direct-current voltage value of a master control power source in the system.

Description

technical field [0001] The invention relates to a power supply monitoring system, in particular to a power supply power loop control and monitoring system, which is suitable for the control and monitoring of the power supply system in the field of intermediate frequency power generation. Background technique [0002] The power supply control and monitoring system is independent of three-way 400Hz, 220V external input three-phase AC power supply. It is mainly used in ground equipment in China due to its advantages of small size and light weight. However, in the existing technology, it is impossible to realize the control and monitoring of the transfer of the three-way intermediate frequency power generation equipment to the electrical equipment, and there are potential safety hazards in the operation of the external intermediate frequency power generation equipment and its feeder lines. Moreover, various indicators of external intermediate frequency power generation equipment...
