Coal mining ZBL-L low voltage leakage protection device 

 

 

Product Description

 

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.

 

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.

Dimension:width(310)×depth(280)×height(410)
