Abstract

The invention provides a monitoring device which is used for the high voltage cable connector status in a mine roadway, wherein, a temperature sensor, a humidity sensor and a current transformer are connected with a data acquisition unit through signal wires; the data acquisition unit, a data storage unit, a keyboard, a display unit, a clock unit and an acousto-optic warning unit are connected with a microcontroller unit through an I/O port; and the microcontroller unit is formed by the connection between a serial port and a communication unit. The invention is simple in structure, low in cost, safe and reliable in performance, and can monitor the temperature, current and humidity of the cable connector in real time, thus being applicable to the monitoring of high pressure cable connection device in the mine roadway and other high voltage electric power equipment.

Description

technical field [0001] The invention relates to a monitoring device for the state of a high-voltage cable joint, including a temperature sensor, a temperature and humidity sensor, a current transformer, a microcontroller unit, a data acquisition unit, a data storage unit, a keyboard and a display unit, an audible and visual alarm unit and a communication unit A monitoring system for the status of high-voltage cable joints in mine roadways. technical background [0002] The mine roadway is continuously extended due to coal mining, and the high-voltage cables continue to extend forward with the advancement of the tunneling equipment for mining coal in the roadway. The deeper the roadway, the more joints used to connect the high-voltage cables. In the power grid, the power grid with a voltage below 1KV is a low-voltage power grid, and the power grid with a voltage of 3-330KV is a high-voltage power grid. Under normal circumstances, a high-voltage cable joint is required every ...
