A live-line intelligent mining cable entry device

Abstract

This application relates to the fields of explosion-proof equipment for mining and power distribution equipment, and discloses a live-indication type intelligent mining cable entry device. The device includes a pressure plate, a pressure plate, a live-indication sensor, a rubber sealing ring, a connecting joint, fastening bolts, and clamping bolts. The live-indication sensor is nested inside the pressure plate, and a rubber protective pad is installed below the sensor. This application uses a Rogowski coil and amorphous alloy material to create a micro-current sensor, which draws power independently for safety warnings, providing start / stop alarms for downstream equipment. It can also transmit data wirelessly. The live-indication function of this application can intuitively identify the operating status of each circuit of the load equipment, solving the technical problem of no safety operation warning after energization in traditional mining cable entry devices. This is especially important in situations where multiple cables are laid in underground coal mine roadways, accurately determining their operating status; the safety warning is even more prominent in high-gas mines.
