摘要
由接触器和晶闸管并联组成的混合式接触器能够有效地防止触头熔焊,从而有利于起重机械的安全运行。本文介绍混合式接触器的结构、触发电路及其保护器。
A hybrid contactor made of contactor in parallel with thyristor can effectively prevent contactor heads from melting. So it is advantageous for safe running of hoisting machines. Present paper introduces the structure of hybrid contactor, triggering circuit and its protector.
