Synchronous MV circuit-breaker with magnetic drive and electronic control

  title={Synchronous MV circuit-breaker with magnetic drive and electronic control},
  author={Carlo W. Cereda},
n 1997 ABB introduced a new series of medium-voltage circuit-breakers with a magnetic drive instead of a spring-based operating mechanism [1]. This solution soon proved to be much more reliable than its predecessor. Following up on the success of the magnetic drive, ABB has now developed a new controlled switching technology which will allow the closing and opening operations to be synchronized with the power network. Synchronous switching, also called ‘point on the wave’ switching, is a…

High voltage synchronous circuit breakers (SCBs) have been widely accepted as a promising solution for reduction of switching surges. It is essential for SCBs to keep the operating times consistent

A permanent magnetic actuator with scheduled stroke curve for vacuum circuit breakers

The load characteristics of vacuum circuit breakers (VCB) are very close to the output characteristics of permanent magnetic actuator (PMA). The combination of PMA and VCB facilitates the development

Optimisation of operating mechanism and drive system for medium voltage circuit breakers

This paper identifies several directions to improve the performances of the operating mechanism for medium voltage circuit breakers in order to get variable moving characteristics of the moving

Pre-insertion Resistors in High Voltage Capacitor Bank Switching

Abstract: The switching of high-voltage capacitor banks for reactive-power or voltage support can produce significant transients. It is well understood that reactors, pre-insertion resistors,

Getting parameters in power systems based on adaptive linear neural network

An approach is proposed using adaptive neural network to detect fault current at the time of vacuum interrupter synchronous breaking short-circuit, to estimate the extinguishing moment of arc for optimally breaking the contact and the effectiveness and speediness of the proposed method.

Improved LSTM Memory Recursive Neural Network Precise Compensation and Prediction for Phase Selective Switching Device

It is concluded that the closer the circuit breaker's closing is to the zero crossing, the less influence it has on the AC system, and a compensation method based on the improved LSTM neural network is proposed to predict the closing delay of circuit breakers.

New technological trends in high-voltage power circuit breakers

This article introduces a comprehensive survey on new trends in high-voltage (HV) power circuit breakers (CBs) technology. Applying the new puffer and the self-blast technologies, the ratings of SF6




Vacuum circuit-breakers have obtained a high level of performance, reliability and safety. This is mostly owed to the advantages of current interruption in vacuum. However, the design of the
