DC dehydrator problems
Thread Content
Our unit invested in three new DC dehydrators. One of them burned out the fuse of the control cabinet (300A) just 3 days after the operation. After replacing the fuse, after half a month of operation, the thyristor burned out. The maximum current of the thyristor is (262A). Why did the thyristor not burn out the first time but did burn out the second time? Is it a load problem or something else? Please give me some advice.
Reply 1# chwyqzcaw I personally think that the maximum current is not equal to the destruction current, so it doesn't matter which one is burned first and which one is burned later. Excessive water content causes overcurrent, and the process may be unreasonable.
