Product Introduction
Mine explosion proof detection relay is JY82 mining flameproof leakage relay of the modified products, 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, with a 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.
