一、概述矿井提升机安全闸交流接触器回路中串联有许多继电器的接点和限位开关的接点。这些接点,数量较多,安装分散。一旦出现安全制动后,分析故障原因,一时较难查出,甚至影响生产。为了准确及时找到安全制动的故障原因,我们研制了SX—1型事故信号显示器,并在淮北局张庄矿投入了工业运行,取得了预期效果。 First, an overview Mine hoist safety gate AC contactor circuit in series with a number of relay contacts and limit switch contacts. These contacts, a large number of scattered installation. Once the safety brake, analysis of the cause of the malfunction, sometimes more difficult to detect, or even affect the production. In order to accurately and timely find the cause of the fault of safety brake, we developed SX-1 accident signal display and put into industrial operation in Zhangzhuang Mine of Huaibei Bureau Bureau and achieved the expected result.
