飞行器上的自动激活锌银贮备电池,激活使用时,总有少量的电解液泄漏,如果不采取绝缘防护措施,将导致电池漏电,严重影响电池性能。通过分析锌银贮备电池可能的漏电模式,提出采取涂覆绝缘胶进行防护的措施。为了达到较好的绝缘效果,选择流动性、固化时间和固化后硬度具有明显差异的硅橡胶、环氧胶和牙托胶3种绝缘涂覆材料,进行了绝缘密封防护对比试验。试验中进行了48 h绝缘性能监测,每小时记录一次数据。试验结果表明:在所有部位都可采用绝缘密封防漏电的措施,差别在于在大多数部位采用硅橡胶进行绝缘保护效果明显,个别部位采用环氧胶效果较好,所有部位采用牙托胶涂覆的绝缘均不好。
Automatic activation of zinc-silver storage battery on the aircraft, when activated, there is always a small amount of electrolyte leakage, if you do not take insulation protection measures, will lead to battery leakage, seriously affecting the battery performance. By analyzing the possible leakage mode of zinc-silver storage battery, a measure of protecting with coated insulating glue is proposed. In order to achieve a better insulation effect, three kinds of insulation coating materials of silicone rubber, epoxy glue and denture gum which have obvious differences in fluidity, curing time and cured hardness were selected, and comparative tests of insulation seal protection were carried out. 48h insulation performance monitoring conducted in the test, the data recorded every hour. The test results show that: in all parts of the measures can be used to prevent leakage of insulation seal, the difference is that in most parts of silicon rubber insulation effect is obvious, the individual parts of epoxy glue is better, all parts of the use of dental adhesive coating Insulation are not good.
