Description

technical field [0001] The invention belongs to the technical field of electronic information, relates to the technical fields of electrical equipment and electrical engineering, and in particular relates to a general-purpose self-generating device for underground coal mines. Background technique [0002] At present, coal mine underground drilling equipment is gradually realizing automation and intelligence. Therefore, the drilling rig needs to be equipped with a large number of sensors, and most of these sensors are low-voltage and weak-current devices. At present, the sensor power supply on the drilling rig is still provided by the explosion-proof electromagnetic starter. During the low-voltage long-distance transmission process, the line loss is high, the number of cables is large, easy to be entangled, difficult to maintain later, and there are potential safety hazards. Due to the requirements for intrinsically safe circuits in underground coal mines, there is no self-g...

Problems solved by technology

At present, the sensor power supply on the drilling rig is still provided by the explosion-proof electromagnetic starter. During the low-voltage long-distance transmission process, the line loss is high, the number of cables is large, easy to be entangled, difficult to maintain later, and there are potential safety hazards

Due to the requirements for intrinsically safe circuits in underground coal mines, there is no self-generating device suitable for underground coal mines on the market.
