1.Overview
KHJ0.five/24 (B) mine security kind clever abrupt quit switch (hereinafter referred to as the abrupt end switch) is ideal for the coal mine with explosive gas (CH4) environment and open up-pit coal mine, coal planning plant, such as the office, as for mine belt conveyor security of electric manage device of the crisis quit sign detection and managing deviation, longitudinal tear safety box and capabilities in the junction box.
two.Electrical perform
two.one.Self-locking perform: When the two sides of the sensor are stretched in area, the sensor realizes self-locking. At this time, the exterior power is removed and the fault sign output is maintained.
2.two.Station alignment: When the sensor operates, it outputs the fault sign and station variety info at the same time, assisting the operator to quickly lock the fault location.
2.3.JCPT signal prompt: When the sensor is running, the high-brightness purple lights on both sides of the sensor light-weight up, indicating the sensor standing.
two.4.Digital registration show of sixty four emergency cease fault details.
three.Electrical parameters
3.one.Rated voltage: DC12V
3.two.Intrinsically risk-free running current ≤40mA
3.3.Make contact with capability: DC24V / .5A
three.four.Following the pad speak to resistance ≤0.1Ω, vibration, shock ≤0.2Ω
3.5.Explosion-proof mark: Exib I .
4.Operating environment
four.one.Ambient temperature: -5 ºC ~ + 40 ºC
4.two.Common relative humidity: not a lot more than ninety eight% (+ 25°C)
four.3.Atmospheric force: 80kPa ~ 106kPa
four.4.No considerable vibration and shock
4.5.Below the coal mine, there are explosive and dangerous environments these kinds of as fuel and coal dust, but there are no events that injury the insulating corrosive gasoline.
