The invention discloses an arc suppression coil testing device and a testing method. In the device, a program-controlled power supply generates an adjustable AC power supply, and a current output relay is connected to the program-controlled power supply to output current to the arc-suppression coil to be tested; The power supply is output to the arc suppression coil to be tested by voltage, the capacitor switching module is connected to the first main control MCU to input or switch the predetermined capacitor, the measurement and control main board is connected to the program-controlled power supply to read the voltage output data and current output data of the program-controlled power supply, and control The start-up and shutdown of the program-controlled power supply, the second main control MCU is connected to the second communication module, the second power management module and the key input module, the second main control MCU operates based on the second predetermined voltage, and in response to the instruction, the second main control MCU generates The first signal is sent to the first main control MCU, and the first main control MCU controls the capacitor switching module to switch on or off a predetermined capacitor based on the first signal.
Description
technical field [0001] The invention belongs to the technical field of arc suppression coils, in particular to an arc suppression coil testing device and a testing method. Background technique [0002] With the rapid economic growth of our country, most distribution networks are grounded through arc suppression coils. With the extensive use of cables, the complete set of arc suppression coil controllers has been continuously put into operation in the entire power grid system. If there is a deviation, the entire power system cannot be properly compensated, thereby expanding the scope of the fault. However, in addition to the operation indication signal provided by the manufacturer, the operation state of the device itself lacks a third-party intuitive test method. In particular, there are many manufacturers, various types of adjustment methods, and the types of faults of arc suppression devices are complex. In order to improve the operation reliability and maintenance effic...
