SDZ—751B型国产数字地震仪的遥控爆炸机和控制器的电源,是使用“GNY—3”镉镍电池;对讲机电源是使用“GNY—0.45”镉镍电池。开始,我们曾用WYJ—305型直流稳压电源充电。在充电过程中,由于电池电压逐渐升高,如不随时调节充电电压,充电电流将不断减小。结果,电池电压充不到标称值。这不但影响野外施工,而且时间一长,电池寿命明显下降。为解决这一问题,我们自行设计了专供3安时和0.45安时镉镍电池充电的GNY—3型和GNY—045型充电机。经过去年冬季在三个数字地震队施工
SDZ-751B-type domestically produced digital seismograph remote control explosive power and controller power is to use “GNY-3” nickel-cadmium batteries; walkie-talkie power supply is the use of “GNY-0.45” nickel-cadmium batteries. In the beginning, we had charged with WYJ-305 DC regulated power supply. In the charging process, due to the battery voltage gradually increased, if not adjust the charging voltage, the charging current will continue to decrease. As a result, the battery voltage does not reach the nominal value. This not only affects the field construction, but over time, battery life dropped significantly. To solve this problem, we have designed GNY-3 and GNY-045 chargers specially designed for charging 3 Ah and 0.45 Ah Ni-Cd batteries. After the construction of three digital seismic teams last winter
