Outline

JJ01 Series auto decompression starter box for AC 380V, three-phase power 300KW following squirrel cage induction motor as the voltage starting with the series with a step-down autotransformer way to improve the impact of the motor to the transmission network.

The main technical parameters
The main technical data table 1. This series of products: 
2. The aerodynamic performance products: 
a starter cabinet to allow the second consecutive start from cold, the start time of each of 15S, at intervals of 30S; 
b starter cabinet to allow one or several consecutive start, but does not exceed the total start-up time specified in the table, should make autotransformer cooling to ambient air temperature before starting again. 
3. This product is starting to run conversion using the current conversion, when the starting current drops to 15 times the rated operating current value, which is equivalent to 80% of rated speed when, from the start the conversion to run. 
4. autotransformer at the start of the protection device is forced conversion by converting the current time to achieve, time tuning the device is not greater than the value specified in the table. 
Product Structure

This product is a box-type protective structure, the auto-transformers, AC contactor, time relay, thermal relay or a combination of protection, relays, cam switches and other components. For 75KW and below the product, the use of automatic control mode, 90KW and above products, all with manual and automatic control mode, switching from universal switch. Autotransformer spare 65% of rated voltage and 80% of two joints, the factory will be connected to the 65% of the joints, fittings and spare 80%.
