Problems solved by technology

[0003] In practical engineering applications, the electromagnetic wave signals in substations or test stations are very complex, and simple signal acquisition cannot effectively distinguish the electromagnetic wave signals radiated by the three phases of circuit breakers A, B, and C, and it is difficult to determine the phases of electromagnetic wave signals radiated by circuit breakers
At the same time, because the action time of the circuit breaker is very fast, it is difficult to capture the electromagnetic wave signal radiated by the circuit breaker

Abstract

The invention relates to a three-phase collection device for an electromagnetic signal of a circuit breaker, and the device comprises a motion collection device, an electromagnetic wave signal collection device, a data collection device and a processing device. The motion collection device and the electromagnetic wave signal collection device are connected with the data collection device, and theprocessing device is connected with the data collection device. The motion collection device is disposed on each phase of the three-phase circuit breaker. The device and a three-phase separation method provided by the invention collect the time axis information of the switching of each phase of the circuit breaker through the motion collection device, and then combine the collected switching electromagnetic information of the circuit breaker so as to distinguish the electromagnetic signal of each phase, which is convenient for judging a fault phase circuit breaker.

Description

technical field [0001] The invention relates to the field of electrical equipment detection, in particular to a three-phase acquisition device for electromagnetic wave signals of a circuit breaker and a three-phase separation method. Background technique [0002] High-voltage circuit breaker is one of the important equipment of power system, which undertakes the tasks of power transmission and control, and its safe operation is very important. How to avoid unexpected power outages, minimize power outage time, reduce equipment maintenance costs, prolong equipment life, and optimize equipment use has become an important topic in the power industry, which contains huge economic and social benefits. The condition-based maintenance of high-voltage circuit breakers usually includes three links: condition detection, condition assessment, and maintenance decision-making. Among them, condition detection and condition assessment are the basis of maintenance decision-making. When the ...
