我们知道彩电允许供电电压在较大范围内变化,而制冷设备中的“心脏”——压缩机,对电源电压要求却较苛刻,如空调机的电源电压不应超出在标定值的±10％以上,否则导致运行异常,甚至烧毁压缩机。 例如一台窗式空调运转时出现噪声明显增大,几十分后“嘀嗒”一声过载保护器动作,切断压缩机电源,约1分钟左右过载保护器复位,压缩机又启动运
We know that TV allows the supply voltage within a wide range of changes, and refrigeration equipment in the “heart” - the compressor, the power supply voltage requirements are more demanding, such as air conditioner power supply voltage should not exceed ± 10% of the calibration value, Above, otherwise lead to abnormal operation, even burn the compressor. For example, when a window air conditioner is running, the noise increases obviously. After several tens of minutes, the “tick” sound overload protector is actuated, the compressor power is cut off, the overload protector is reset in about 1 minute, and the compressor is started
