可语音报警的便携式发电机功角测量仪
摘要：
本实用新型公开了一种可语音报警的便携式发电机功角测量仪，解决了现有功角测量仪体积偏大无法自动语音报警的问题。包括发电机（10）、电源（1）、交流电压采集器（2）、键相信号采集器（6）、CPU（8）和发电机功角显示器（9），在交流电压采集器（2）上分别设置有三相电压输入端子，在键相信号采集器（6）上设置有键相信号输入端子（7），发电机（10）的转动轴（11）上设置有键相装置（12），键相装置（12）的输出端与键相信号输入端子（7）相连接，在CUP（8）分别与发电机功角显示器（9）和语音报警器（13）连接。实现了当发电机功角达到70°时的自动报警的功能，大大提高了工作效率。
摘要（英）：

The utility model discloses a portable generator power-angle measuring device capable of voice alarming, and solves the problems that in the prior art a power-angle measuring device is large in size and cannot give voice alarm automatically. The device comprises a generator (10), a power supply (1), an AC voltage collector (2), a key-phase signal collector, a CPU and a generator power-angle display (9). Three-phase voltage input terminals are arranged on the AC voltage collector (2), a key-phase signal input terminal (7) is arranged on the key-phase signal collector (6), a key-phase device (12) is arranged on a rotary shaft (11) of the generator (10), the output terminal of the key-phase device (12) is connected to the key-phase signal input terminal (7), and the CPU (8) is connected to the generator power-angle display (9) and a voice alarm (13). The device is capable of automatically giving the alarm when the generator power-angle reaches 70 degrees and work efficiency is largely improved.
