Abstract

This application discloses an electromagnetic load switch simulation test device, including an electric closing module, a fault current holding module, a mechanical closing module, a switch position acquisition module, and an I / O control module for sending closing position remote signaling to the closing device. The input terminal of the electric closing module is connected to the AC power supply, and the output terminal is connected to the input terminal of the switch position acquisition module. The input terminal of the fault current holding module is connected to the three-phase current, and the output terminal is connected to the input terminal of the switch position acquisition module. The mechanical closing module, the electric closing module, and the fault current holding module enable the switch position acquisition module with an OR logic relationship. The output terminal of the switch position acquisition module is connected to the I / O control module. This application has functions such as "closing upon power restoration and opening upon power failure," "maintaining the closed position during a fault," and "mechanical forced closing," and simulates different closing position remote signaling situations that occur during the operation of an electromagnetic load switch.
