Problems solved by technology

Since the current standard sources on the market are all low-power signal sources that can meet the accuracy requirements and cannot meet the power requirements of the FTU system control power supply, the current test process needs to separate the three-phase voltage acquisition input of the FTU device from the system control power input. Connect the three-phase voltage acquisition input terminal to a low-power signal source, and connect the system control power input terminal to a high-power source or joint detection of mains power. This process is cumbersome and time-consuming.

Abstract

The invention relates to a power distribution terminal based detection method and system, and aims at providing the detection method and system needless of separating the three-phase voltage collecting input end from the system control power input end before detection. The detection method comprises that a signal command input from the external is received; the power of a received signal is amplified; and the processed signal is output. The integral power distribution terminal is detected, the method and device satisfy onsite application more, the practical condition of the voltage signal canbe detected more accurately during operation of the terminal, and the method and system are suitable for the power field.

Description

technical field [0001] The invention belongs to the technical field of power distribution terminals, and in particular relates to a detection method and system based on power distribution terminals. Background technique [0002] There is a large demand for power distribution terminal detection experiment source applications. Since the power distribution terminal FTU is convenient for on-site application, the wiring adopts standard aviation plug-in wiring to connect the three-phase voltage acquisition input terminal with the system control power input terminal. Therefore, a standard The source can not only meet the 0.05-level accuracy requirements, but also meet the power requirements of the FTU system control power supply. Since the current standard sources on the market are all low-power signal sources that can meet the accuracy requirements and cannot meet the power requirements of the FTU system control power supply, the current test process needs to separate the three-ph...
