| description | The utility model relates to the technical field of electrical engineering, and discloses a high-voltage coal conveying belt conveyor pull switch electrical loop which is arranged among a high-voltage coal conveying belt conveyor site, a belt conveyor head control box and a DCS (Distributed Control System). Comprising a pull switch, an intermediate relay and a leakage air switch. The pull switch, the intermediate relay and the electric leakage air switch are connected in series to form a loop; a power supply is arranged in a head control box of the belt conveyor and independently supplies power to a series loop; a normally open contact of the intermediate relay is connected in series in an accident tripping circuit of the high-voltage coal conveying belt conveyor; the electric leakage air switch is also provided with an auxiliary contact which is connected in series in the DCS system; the DCS system is used for converting the received leakage air switch signal into a pull switch power supply disappearance sig |
