Coal mining ZBL-L low voltage leakage protection device
Product Introduction
ZBL-L Mine low voltage leakage protection device uses a modern design technology leakage protection device,
compared with the same type of product safety performance good economic advantages, ZBL-L mine
low voltage leakage protection device is suitable for coal mine methane and coal dust with a dangerous place,
as a low voltage 380V ~ 1140V ungrounded system leakage protection.
Main Parameter
Control voltage:380V,660V,1140V.
Power supply: control voltage.
bus segment number:1.
voltage level: 380V 660V 1140V
action resistor values 3.5K±20% 11K±20% 20K±20%
latching action resistor values 7K±20% 22K±20% 40K±20%
Action time: branch export time 30 milliseconds; Total exports time 300 milliseconds. Can be arbitrarily set.
Ability to adapt to changes in the power supply: Power supply change in the rating of 75% to 110%, the resistance value of the device leakage action, leakage blocking resistance value and operating time of the error is less than 20%.
Low voltage system capacitance change adaptation: When the system capacitor 0.1μf ~ 1μf range of changes, thedevice leakage resistance movement, leakage blocking resistance value and operating time of the error is less than 20%.
Dispersion leakage resistance resolution: Action resistor setting value 20% +2 K.
Relay export output: total exports and exports into the line corresponding to one, are normally open dry contact, contact capacity 1A; 380VAC.
