Description

Product Introduction

Mine explosion proof detection relay is JY82 mining flameproof leakage relay of the modifiedproducts, the relay has explosion-proof enclosure, suitable for the coal mine and the surrounding gas (methane).Using voltage

AC 380V or 660V, 50Hz is ungrounded three-phase three-wire networks for industrial enterprises, when the risk of accidents caused by line leakage,can play the role of automatic protection, in addition to the network capacitive current, witha significant ability to compensate.

Mine explosion proof detection relay apply to following work environment:

l,height is not more than 2000 meters above sea level;

2,surrounding medium temperature is not higher than + 40 °C, not below - 50 °C.

3,the surrounding air relative humidity is not higher than 95% of the environment (+ 25 °C);

4, in the absence of strong vibration, bumpy;

5,in the absence of enough to corrosive action on metals, and the damage of the insulation gas environment;

6,without a drop of water and snow and rain hit the environment;

7,can be used for methane and coal dust in the mine danger;

8,with the vertical inclination of installation does not exceed 15 degrees.
