An Approach of The Analytic Hierarchy Process to Acquire The Weighting Factor of High Voltage Circuit Breaker Health Index

2020 International Conference on Technology and Policy in Energy and Electric Power (ICT-PEP), 2020
The circuit breaker (CB) health condition greatly affects the reliability of CB, which eventually will affect the reliability of the power system. A method that can be used to determine CB health conditions based on multi criteria is the calculation the ...

Worldwide Reliability Survey of High-Voltage Circuit Breakers

IEEE Industry Applications Magazine, 1995
CIGRE 13.06 Working Group has conducted two worldwide reliability surveys of the reliability of high-voltage circuit breakers of 63 kV and above. The first enquiry included 78000 breaker-years of "in-service data" from 102 companies in 22 countries during the years 1974 through 1977 and included all interrupting technologies.

Development of High Voltage Vacuum Circuit Breakers in China

2006 International Symposium on Discharges and Electrical Insulation in Vacuum, 2006
This paper introduces research work on the development of high-voltage (HV) vacuum circuit breakers (VCBs) in China from its starting point in 1989 to 2006. In this period, a 126-kV two-breaks VCB prototype and a 126-kV single-break VCB prototype were developed. A latest 252-kV single-break interrupter prototype is introduced. Five HV VCBs technologies

Comparison of Synthetic Test Circuits for Ultra-High-Voltage Circuit Breakers

IEEE Power Engineering Review, 1996
Three synthetic test circuits to verify the interrupting performance of UHV circuit breakers (765kV, 63kA, 50Hz) are compared on aspects of equivalence, operation, required capacitive energy and applicability. The comparisons show that, although each circuit has its own merits, the EPIC circuit appears to be very attractive.

Research on Fault Diagnosis of High-Voltage Circuit Breaker Based on Support Vector Machine

International journal of pattern recognition and artificial intelligence, 2019
In order to realize the diagnosis of the state of the high-voltage circuit breaker in the smart grid, the wavelet-packet technique is used to extract the characteristic value of the signal of the dynamic contact of the high-voltage circuit breaker.

A Multiorifice Interrupter for High-Voltage Oil Circuit Breakers

Transactions of the American Institute of Electrical Engineers, 1943
High-voltage oil circuit breakers for high-speed operation generally use some form of multibreak contact arrangement. These breakers perform satisfactorily but lack the simplicity of the conventional slower-speed two-break construction. The development of an unusually effective multi-orifice oil-flow interrupting unit now makes it possible to reduce ...

High-voltage oil circuit breakers for rapid reclosing duty

Electrical Engineering, 1944
Experience has shown that high-speed reclosing of circuit breakers on high-voltage transmission lines is of considerable value in maintaining system stability and continuity of service. This paper describes a new line of outdoor oil circuit breakers and the special design features which make them suitable for 20- and 35-cycle reclosing duty at voltages
