JJ1 type auto-decompression start control cabinet
Product features
GCS (BFC) low-voltage withdrawable switchgear is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. Used as a three-phase AC frequency of 50 (60) HZ, rated working voltage of 380V (440V), (660V), and rated current of 6300A and below in power distribution, motor centralized control, and reactive power compensation The low-voltage complete set of power distribution device adopts standard modular design. Each functional unit is relatively independent. The outlet unit can be installed up to 22 channels. The mechanism adopts a screw propulsion mechanism, which is stable and lifeable, ensuring that the same unit can be interchanged and improving power supply Reliability!
Technical parameters
Start-up performance of this series of products:
The starting cabinet allows two consecutive starts from the cold state. Each start time is 15s, and the interval time is 30s.
The starting cabinet allows one or several consecutive starts, and the total starting time does not exceed the regulations in Table 1. The autotransformer should be cooled to the ambient air temperature before restarting.
The starting-to-running conversion method of this product adopts current conversion. When the starting current drops to 1.5 times the rated working current value, which is equivalent to 80% of the rated speed, the starting-to-run conversion is performed. The current-time conversion device is realized by powerful conversion. The time setting value of this device is not greater than the value specified in Table 1.
The protection of the autotransformer at startup is realized by forced conversion of the current-time conversion device. The time setting value of this device is not greater than the value specified in Table 1.
