电空接触器是工矿电力机车中不可或缺的重要电气装置之一。电空接触器采用电空传动,用以接通或断开带有负载的主电路或实现非电对象的控制、保护和调节的电气设备。它既是主电路电器又属于控制电器。在电力机车运用中具有非常重要作用。这里着重分析其结构、工作原理、灭弧原理、并将其故障原因以及保养措施具体化,以便于维护检修,提高机车运用效率。
Electric air contactor is one of the most important electrical devices in industrial and mining electric locomotives. Electro-pneumatic contactor using electro-pneumatic drive to switch on or off the load with the main circuit or non-electrical objects to achieve the control, protection and regulation of electrical equipment. It is both the main circuit and electrical control appliances. In the electric locomotive has a very important role. Here focused on the analysis of its structure, working principle, the principle of arc, and its causes of failure and maintenance of concrete, in order to facilitate maintenance and improve locomotive efficiency.
