摘　　要：新型智能混合式交流接触器是一种将单片机技术、电力电子技术、通信技术引入交流接触器而形成的一种新型低压控制电器。将Modbus总线技术引入新型智能混合式交流接触器,使之具有与主控计算机双向通信的功能,其结构简单、使用方便,各项性能指标明显提高。介绍了新型智能混合式交流接触器的工作原理、Modbus总线特点、Modbus通信协议在交流接触器中应用的设计方案,并对Modbus的两种传输模式在实际应用中的作用进行了比较。New type intelligent hybrid AC contactor is a new-style low-voltage electrical apparatus which introduces single chip microproccessor technology, power electronic technology and communication technology into AC contactor. This new type of intelligent hybrid AC contactor that can intercommunicate with control-PC is convenient for us when using Modbus fieldbus technology, and its structure is simple, also its capability is enhanced greatly. The function of new type intelligent hybrid AC contactor, characteristic of Modbus fieldbus and communication function realization for new type intelligent hybrid AC contactor were mainly introduced. At the same time, effects of the two modes of Modbus fieldbus in the current application were compared.
