Specific implementation mode：
With reference to specific embodiments and the drawings, the present invention is further described.
As Figure 1-Figure 2, described in the present embodiment it is a kind of startup control method of air compressor machine, the startup control method
Include the following steps：
First, power on, system detectio current device state determines whether abnormality, if there is abnormality：Into one
Step judges whether abnormality reaches the situation for needing hard stop, if so, hard stop is protected and shows stoppage protection
Correlation instruction and prompt；If abnormality is not need the situation of hard stop, do not shut down, but issues warning signal and show
Relevant instruction and prompt；
If equipment state without exception, whether further detection device entry condition reaches, if not up to entry condition,
It exits, does not start；
If reaching entry condition, it is first closed star-like circuit contactor, delay 0.1 after star-like circuit contactor starts~
0.3 second, and further whether detection device state is abnormal during delay, if there is exception, exits；If it is without exception, then close
Main contactor and triangular form circuit contactor to be closed, is then delayed 5-7 seconds, star-like circuit contactor separation disconnects, start completion,
Air compressor machine enters normal operating conditions.
In above-mentioned control method, the delay time after the star-like circuit contactor starts is preferably 0.2 second；Main contactor
Delay time after being closed with triangular form circuit contactor is preferably 6 seconds.
In above-mentioned control method, start required voltage by being first closed star-like circuit contactor and being delayed to reduce,
Reduce load, restarted using the inertia and kinetic energy of its startup and be closed main contactor and triangular form circuit contactor, make equipment by
The impact smaller arrived keeps equipment operation more stable.Meanwhile it can also reduce impact when equipment starts to entire power utilization environment.
The present invention also provides a kind of startup control system of air compressor machine, including main controller 1, state is equipped in main controller 1 certainly
