Analysis, Design and Dynamic Simulation of Novel Limited Swing Angle Torque Permanent Magnet Motor for High Voltage Circuit Breaker Application

Abstract

In this paper, a novel limited swing angle torque permanent magnet motor (LSATPMM) is proposed, and the operating principle of the circuit breaker of the proposed LSATPMM and a mathematical model are analyzed. The characteristics of the high voltage circuit breaker (HVCB) of the proposed machine are analyzed and calculated by numerical finite element analysis methods. The co-simulation of the Maxwell Circuit Editor and Ansoft Maxwell is used to analyze the dynamic characteristics of HVCB. The advantages of the presented operating mechanism for LSATPMM, such as the ability to adjust the opening and closing torque characteristic, high reliability, robust drive system and fault tolerance, are discussed. Finally, a prototype of LSATPMM is created and tested; and the characteristic curve of position versus torque is acquired in order to confirm the proposed design.

Research on Motor Drive Technology for an Operating Device of 126 kV Vacuum Circuit Breaker

“…In addition to meeting the mechanical requirements of the arc-extinguishing chamber, it must also ensure the longterm reliability of the circuit breaker. Due to the high number of moving parts and the complex mechanical structure, the traditional operating device is the most crucial component that can cause the malfunctioning of a high voltage circuit breaker [1,2]. With the help of the linkage mechanism, the motor operating device can convert the rotary motion of the motor into a linear motion to realize the opening/closing operations of the circuit breaker, and the dead point position can be used to eliminate the closing holding device, which simplifies the complexity of the operating device.…”

“…On the other hand, the rotary machines are also presented for HVCB applications in [34,35]. However, the HVCB with rotary machines has a larger volume than the HVCB with PMA, which are linear machines, owing to the lever linkage structure.…”
