该空调器通电延时启动保护器由MCS-51单片机AT89C51来实现功能：在电源电压不稳定的地方，当空调器断电后无论什么时候再来电，都不会因此而产生烧毁压缩机得故障，也不需人为反复重新将空调器按键启动开机与设置工作模式和状态了。可以保证在任何情况下出现瞬间停电时都能使空调机得到保护并自动安全地进入正常工作状态.避免因瞬间停电造成压缩机起动负荷过大而受损.有效地减少故障,延长使用寿命.-This air-conditioner circular telegram time delay start protector realizes the function by MCS-51 monolithic integrated circuit AT89C51: In supply voltage unstable place, after air-conditioner power failure regardless of when comes the electricity again, all cannot therefore produces burns down the compressor to result in the breakdown, also did not need artificial again starts repeatedly the air-conditioner pressed key starting and the establishment working pattern and the condition.May guarantee has the instantaneous power cut when any situation all can enable the electric refrigerator, the air conditioner to obtain the protection and the automatic security enters the normal work condition. Because avoids the instantaneous power cut creating the compressor to start the load oversized to suffer injury. Reduces the breakdown effectively, the extension service life.
