Product Description
Note: the first working combination: 8 hours working time; uninterrupted working system; short-time working system; 3 times each hour during intermittent periodic duty , and 6 times each hour during the aperiodic operation, and then the temperature should be the same as that of the ambient.
The second working combination: 8 hours working time; uninterrupted working system; short-time working system; 3 times each hour during intermittent periodic duty , and 12times each hour during the aperiodic operation, and then the temperature should be the same as that of the ambient.
1) the main technical parameters see table 1
2) the starting performance
a. 2 times of uninterrupted starting, starting time 15s, interval time 30s
b. one time or several times of uninterrupted starting., the total starting time see table 1. the temperature of the autotransformer should be the same or lower than the ambient temperature when restart- current transfer realize the transfer from starting to operation: when the starting current is 1.5 times lower than the rated working current, 4) the protection of the autotransformer is by forced transfer of the current-time equipment
