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 mechanical drive, which has already been applied e.g. in minimum oil-breakers, has hardly been changed. With the introduction of an actuator with permanent magnetic limit positions and electromagnetically controlled motion, the next generation of vacuum circuit-breakers is launched promising an increase in…

Synchronous MV circuit-breaker with magnetic drive and electronic control

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

SYNCHRONOUS MEDIUM VOLTAGE CIRCUIT BREAKERS: ABB SOLUTION BASED ON MAGNETIC DRIVE AND ELECTRONIC CONTROL

The present paper describes the principles and the customer-value of synchronous medium-voltage circuitbreakers, available with SF6 and vacuum interrupters. These circuit-breakers have three

An Electromagnetically Actuated Vacuum Circuit Breaker Developed by Electromagnetic Analysis Coupled with Motion

Vacuum switching devices (circuit breakers and contactors) dominate the current market of medium voltage devices. In the paper a classification of electromagnets and actuators which are used in MV

Characteristic analysis and design of a novel permanent magnetic actuator for a vacuum circuit breaker

In this study, a novel permanent magnetic actuator (PMA) termed a separated permanent magnetic actuator (SPMA) is proposed. The efficiency of the proposed SPMA is significantly higher than a

Investigations on control tactics of phasing vacuum switches when synchronized closing capacitor banks

Capacitor banks are usually used for reactive power compensation in power system energized by a vacuum switch which often results in a surge current and overvoltage in the system. The phasing vacuum

In this paper, the authors aim to present the modelling, simulation and experimentation of an electromagnetic actuator used in the construction of vacuum contactors. In order to validate the

Multi-domain mechatronic approach for the design of a vacuum contactor actuation drive

This paper illustrates the development, up to prototype stage, of an electromechanical actuation system for a medium-voltage vacuum contactor. Such development is carried out using a multi-domain

Development and prototyping of a rotary-linear actuation drive for vacuum contactors

TLDR
A rotary actuation system based on a switched reluctance motor and a suited coupling mechanism and results obtained by testing the prototype motor and coupling mechanism are presented, confirming the expected performances.

Simulating Research on Fuzzy PID Control to Synchronous Closing Operation of Permanent-Magnet Vacuum Circuit Breaker

TLDR
A fuzzy PID controller was designed and simulated, and the simulating results show that this controller can work efficiently in the course of synchronous closing though parameters varying, and prove its high precision and adaptability.
