Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a high-voltage circuit breaker comprehensive test device and method based on the ubiquitous electric power Internet of Things. Background technique [0002] The high-voltage circuit breaker is the main power control equipment in the substation. When the system is running normally, it can cut off and connect the no-load and load current of the line and various electrical equipment; when the system fails, it cooperates with the relay protection , can quickly cut off the fault current to prevent the expansion of the scope of the accident. Therefore, the quality of the high-voltage circuit breaker directly affects the safe operation of the power system. The function is to cut off and connect the load circuit, and cut off the fault circuit to prevent the expansion of the accident and ensure safe operation. The high-voltage circuit breaker needs to break ...
