Start-up time after the pump drive inverter trips
Thread Content
After the pump’s frequency converter trips, there is a startup time required to protect the converter; here it is 60 seconds. How long is it in your area? Does a shorter auto-start time have a significant impact on the frequency converter?
Our high-voltage frequency converters usually take 10-15 minutes; I’m not sure about the low-voltage ones, but it’s probably to ensure that the capacitors are fully discharged
The range is quite wide, and the equipment used in different positions varies; it is essential to follow the equipment’s instruction manual when operating it. This is called a basis. In the event of an accident, this can be used as direct evidence. If an accident happens and you say it was mentioned on a forum,,, Hehe, this isn’t your basis:lol
The time interval before restarting after a frequency converter trips should be determined in accordance with the instructions, rather than following a fixed time limit; since each pump is different and the issues that need to be addressed vary, the downtime required also differs from one pump to another. Of course, what the moderator meant is the downtime caused by a frequency converter tripping, with no other factors at play; however, this situation occurs relatively rarely.
