The starting current of the freeze-dryer is high, and it rises slowly until tripping occurs
Thread Content
There is a H-4200WMP type air conditioner manufactured by Hangzhou Hanyuan in my workshop, and today it suddenly activated its overcurrent protection feature. After 5 minutes, it can be started, but the starting current increases, rising slowly until an overcurrent occurs. During this process, other parameters are normal. Please ask some expert for guidance!
I wonder what type of compressor it is? Compressors should generally be started under no-load conditions; if they are started under load for any reason, it will result in a high starting current
1# cshyou starts under load, or there is a mismatch.
Could there be a dirty blockage or an ice blockage at the capillary?
It’s probably due to starting under load or a mismatch! We’ve encountered similar problems before; it was caused by a mismatch!
