The XJ01 series autobuck and decompression starting cabinet is a kind of starting equipment specially designed for three-phase squirrel-cage induction motor, which aims to reduce the influence of the motor on the power grid when starting by the method of autotransformer decompression. The following is a detailed introduction of the product:
Product Features:
The improved shell technology is beautiful, the shell is strong, easy to connect, especially suitable for the application scenario above 115KW
The use of copper wire and line, improve the appearance of the process at the same time, eliminate the problem of line heating
It is suitable for three-phase squirrel-cage induction motor with AC 50Hz, voltage 380V and power up to 350KW
Operating environment:
Suitable for indoor installation, the altitude is not more than 2000 meters
The temperature of the surrounding medium is not higher than +40ºC, not lower than -10ºC, and the relative humidity of the air is not greater than 85%
Installation inclination does not exceed 5 degrees, no explosive dangerous media, no corrosive metal and destroy insulation gas and conductive dust
Performance parameters:
When starting the motor, the starting current of the power supply line does not exceed 3-4 times the rated current of the motor
The starting time is 30 seconds (including the sum of one or several consecutive starting times), and then the cooling time is not less than 4 hours before starting again
The product is not suitable for frequent starting operation
Structural features:
Cabinet protection structure, including air switch, autotransformer, AC contactor, thermal relay, time relay and other components
Manual automatic mixing control type, time relay is adjustable, can be freely adjusted in 1-99s control starting time
Autotransformer with rated voltage 65% and 80% taps, users can choose 1 according to needs.
Installation and setup:
After installation and before use, you must check whether the wiring is wrong according to the wiring schematic
Adjust the current setting value of the thermal relay and comprehensive protector according to the motor current
Adjust the starting time appropriately according to the motor load weight
Starting operation:
Automatic operation: check is completed, turn on the power, press the "start" button, and observe whether to switch according to the set time when starting
Manual operation: Rotate the universal switch handle to the "manual" gear, press the "start" button first, and then press the "run" button when the motor is started and close to operation.
Through the above introduction, we can see that the XJ01 series autobuck vacuum starting cabinet has not only made a number of improvements in technology, but also has significantly improved in terms of practicality and safety, which is suitable for a variety of industrial application scenarios, especially in the need for smooth start of large electric power
