Abstract
The utility model discloses a solid soft starting apparatus of a small-and-medium-sized air compressor and relates to a starting apparatus. The solid soft starting apparatus comprises a power supply, a switch circuit, a starting circuit, and an electromotor. When the electromotor is started, an electric switch K1 is switched on and an electric switch K2 is switched off. The electric switch K1 and the starting circuit provide starting power for the electromotor. After the electromotor is started, the electric switch K2 is switched off and the electric switch K2 is switched on. Current successively passes the switch circuit and the electric switch K2 to provide operative current for the electromotor. The solid soft starting apparatus is capable of decreasing impact on a power grid when the air compressor is started, and substantially reduces power consumption in the air compressor starting process so as to achieve purposes of environmental friendliness and energy conservation.
