在时间剖面上24道总是与爆炸信号道重合的,从而使爆炸信号起跳不清楚。为了解决这个矛盾,我们在队党支部领导下,认真学习了中共中央《1974》26号文件,在毛主席“独立自主,自力更生”方针指引下,自己动手设计,在664型基地回放仪上装了一个“感应切除器”。通过生产实践证明,效果较好。现将情况介绍如下。原理(图1) 1、当数字管亮时(地震道为24道),原自锁继电器工作,而在未跳第一道时,
In the time profile 24 always coincides with the blast signal track, so that the blast signal jump is not clear. In order to resolve this contradiction, we conscientiously studied the “1974” Document No. 26 of the Central Committee of the Communist Party of China under the leadership of the Party Branch of the CPC Central Committee. With the guidance of Chairman Mao’s principle of “independence and self-reliance, self-reliance,” we conducted a hands-on design and installed a 664 base playback device Induction Cutter. Proved through the production practice, the effect is better. Now the situation is as follows. Principle (Figure 1) 1, when the digital tube light (seismic track is 24), the original self-locking relay work, and did not jump in the first track,
