为适应我矿生产需要,设计了一种简单实用、安全可靠的竖井提升信号系统电路,于1986年上半年安装运行,经过一年多的使用,达到了良好效果。本电路实用于多层次的竖井作业。 (一)电路原理如附图所示,当井下某中段(如我矿-214米中段)发出要罐信号(如甲罐)时,按下2ZA,电源经2—JS—7—1AK—2AK—3AK—71(1)—4,通过电铃回到0线,电铃2L、5L同时有电发声,2SJ线圈从4通过自身触头回到0线有电吸合,灯16D通过2SJ常开触头回到
In order to meet the needs of mine production, a simple, practical, safe and reliable shaft hoisting signal system circuit was designed and installed in the first half of 1986. After more than a year of operation, good results were achieved. This circuit is used for multi-level shaft operation. (A) The circuit principle As shown in the figure, when a certain underground (such as my mine -214 meters in the middle) issued a signal to the tank (such as a tank), press 2ZA, power by 2-JS-7-1AK-2AK -3AK-71 (1) -4, back to the 0 line by the bell, bells 2L, 5L at the same time audible sound, 2SJ coil from 4 through their own contacts back to 0 line with electric sucking, lamp 16D through 2SJ often open Head back
