The invention belongs to the technical field of aviation product testing, and relates to a clutch low-voltage disengagement test device which is composed of a power supply system, a voltage regulating module, a digital display voltmeter, a clutch state indicating lamp, a test cable, a fuse and the like. A 28V direct current and 220V alternating current mutual random switching power supply mode is adopted, dual-redundancy backup is carried out, and the power supply reliability of the system is improved; the connection line is optimized in design and is simple and clear; whether the clutch is in a normally-closed state or a normally-open state can be judged through signal acquisition, and a clutch state indicator lamp is arranged; electromagnetic shielding processing is carried out on the cable to prevent electromagnetic interference from influencing a test result in a test time and improve the robustness of the system; an integrated circuit design is adopted, a one-way silicon controlled rectifier is integrated inside, an RC (Resistance-Capacitance) absorption loop is integrated with a power supply circuit and the like, and stepless adjustability from 0V to 30V is realized; and a portable box body framework is adopted, so that the device can be carried by a single person, and outfield testing and troubleshooting and positioning are facilitated.
本发明属于航空产品测试技术领域,涉及一种离合器低电压脱开试验装置,由电源系统、调压模块、数显电压表、离合器状态指示灯、测试电缆、熔断器等组成。采用28V直流、220V交流相互任意切换供电方式,进行双余度备份,提高系统供电可靠性;连接线路设计优化,简洁明了;通过信号采集可以判断离合器处于常闭状态还是常开状态,具备离合器状态指示灯;电缆进行电磁屏蔽处理,防止测试时机上电磁干扰影响测试结果,提高系统健壮性;采用集成电路设计,内部集单向可控硅、RC阻容吸收回路集电源电路等于一体,实现0V到30V无级可调;采用便携式箱体架构,可单人携带,便于外场测试及故障排查定位。
