Structure

JJ1B series auto voltage reducing staring cabinet is designed into the cubicle type protection structure, made up of auto transformer,circuit breaker,AC contactor, thermal relay, current-time converter,current-time converter, current-voltage meter. There are three working ways that is the manual control,automatic control and remote control,hereinto, the manual control and automatic control are performed by transfer switch, and the remote control is performed by the remote-control input connection terminal.

The auto transformer have two sets of taps of rated voltage up to 80% and 65%. And when the product leaves factory,it is connected to the tap of rated voltage up to 65%. The product is also connected to the tap of rated voltage up to 65%. The product is also connected to the tap of rated voltage up to 80% according to customers' requirements. In additon, user can indicate the tap connection position while placing an order.

Working conditions

JJ1B series auto-voltage reducing starting control cabinet is installed indoors,shall run normally under following conditions:
1) Altitude should not exceed 2000m;
2) Ambient air temperature should be -5°C~+40°C,and within 24h, the average temperature should not exceed+35°C;
3) Air relative humidity should not be higher than 50% at max temperature of +40°C,the higher relative humidity is allowable at the lower temperature, the mean min temperature should not exceed +20°C in the most wt month,and in this month, the mean max relative humidity should not exceed 90%. In addition, some precautions must be taked against possible condensation resulted from the change of temperature;
4) Vibration whose amplitude should not exceed 0.5mm and the frequency should not exceed 600 times/min;
5) Inclination between the installation plane and horizontal plane should not exceed 5 °;
6)Air pollution grade:3;
