Abstract

The invention provides a high-voltage switch device based on dynamic invertible electronic load simulation and a test method thereof, and the device comprises a console, a switch fault waveform library, a CPU control module, a digital-to-analog conversion module, a power element, a switching value output module, a voltage and current collection module, and a wave recording module. The console is used for receiving switch fault waveform data imported by the upper computer and storing the switch fault waveform data in a switch fault waveform library, the CPU control module is used for receiving the switch fault waveform data issued by the console, and the digital-to-analog conversion module is used for outputting an analog quantity according to a received digital signal to control the power element. And the switching value output is used for converting the received digital signal into an opening position, a closing position or an energy storage position signal of an analog switch position and outputting the opening position, the closing position or the energy storage position signal to input detection of a power distribution terminal. According to the invention, detection of switching-on and switching-off of the power distribution terminal, a wave recording function of an energy storage loop and a health state analysis function of a primary switch and filing of test data can be automatically completed, and a test result is analyzed and a test report is output.

Description

technical field [0001] The invention relates to the technical field of power system distribution automation, in particular to a high-voltage switching device based on a dynamic reversible electronic load simulation and a testing method using the device. Background technique [0002] With the rapid development of the national power system and the implementation of the Internet of Everything, the detection range of the power distribution terminal also needs to be increased. The State Grid has proposed that the terminal detect the state monitoring and recording of the opening and closing of the 10Kv high-voltage switch primary equipment, energy storage circuits, etc., and according to Waveform analysis reveals the health status of the primary switch. [0003] Since a switch with various faults is required to verify the function of the power distribution terminal, it is not easy to realize in mass production and research and development. Therefore, a dynamic and invertible elect...
