SF6 High Voltage Circuit Breaker Contact Systems Under Lightning Impulse and Very Fast Transient Voltage Stress
In the past few years gas insulated high voltage circuit breakers have improved considerably, in particular with respect to required drive energy for operation, compactness and reliability. A further reduction in size implies increasing operational field stress inside the breaker and, thus, a reduction in built-in safety margins. If the design comes closer to its physical limits, in particular ...
متن کاملDevelopment of non-intrusive monitoring for reactive switching of high voltage circuit breaker
High-voltage circuit breakers are among the most important equipments for ensuring the efficient and safe operation of an electric power system. On occasion, circuit breaker operators may wish to check whether equipment is performing satisfactorily and whether controlled switching systems are producing reliable and repeatable stress control. Monitoring of voltage and current waveforms during sw...
متن کاملOn-line Monitoring System based on Vibration Signal of High Voltage Circuit Breaker
High voltage circuit breaker is one of the most important switch apparatus in electrical power system. It play a role in the switch control, which can be used to switch the operating mode during normal operation (the equipment run or quit). In order to ensure the normal operation of the grid, it can be removed quickly when a malfunction on the device or circuit. Real-time online monitoring of h...
متن کاملDevelopment of an Overall Condition Monitoring System of High Voltage SF6 Circuit Breaker
With the rapid development of arts of sensors and IT, on-line monitoring of circuit breaker is now desirable and practical for electric power utilities. This paper describes a set of overall on-line monitoring systems that was developed to control and monitor the condition of SF6 circuit breaker with different type of sensors and microcomputer based controller. The aim of the developed system i...
متن کاملHigh-Voltage Circuit-Breaker Fault Diagnosis Based on Mechanical Vibration Signals
In order to guarantee the operation stability of high-voltage circuit-breaker, this paper extracts eigenvector of vibration signals based on mining of characteristic entropy of the wavelet packet obtained under the state of circuit breaker. Besides, the eigenvector of various fault samples is adopted as the input information of the BP network. After that, the author conducts training of the wel...
