Remote overtemperature alarm for power cable head

Abstract

The invention discloses a remote overtemperature alarm for a power cable head, and the remote overtemperature alarm comprises a signal collecting circuit, a signal judging circuit and an alarming communication circuit, wherein the signal collecting circuit collects a temperature signal from the junction point of the power cable head and the output of the signal collecting circuit is connected with the signal judging circuit; the output of the signal judging circuit is connected with the alarming communication circuit; and the alarming communication circuit is connected with a network distribution intelligent control center or the mobile phone of an electrician. The remote overtemperature alarm can be used for realizing on-line monitoring and intelligent alarming for temperature at the junction of the conducting wire of the power cable head; when the temperature at the junction of the outlet conducting wire of the running power cable head exceeds a specified value, an overtemperature signal is immediately transmitted to an emitting circuit to carry out remote alarming; an operator on duty obtains an alarming condition and reaches the field to handle the accident at once; the time of handling the failure of electrical equipment is shortened; the damage rate of the equipment is reduced; the power-supplying reliability is improved; and the enterprise benefit and the social benefitare increased.

Description

technical field [0001] The invention relates to a remote alarm technology for over-temperature of a power cable head, which is applied to a remote alarm for over-temperature of a wire contact of a cable head during power supply operation of a power distribution network. Background technique [0002] At present, with the rapid development of industrial and agricultural production, the rapid improvement of the national economy, the continuous improvement of people's living standards, the unprecedented development of the power industry, and the rapid development of the national power grid construction. Electric energy is sent to thousands of households through the distribution network. Since the current distribution network cannot be monitored in real time, it is basically caused by a heating fault at the connection of the power cable head wire, burning out and power outage. The user will notify the maintenance personnel to carry out equipment maintenance. The long dragging tim...

Electric energy is sent to thousands of households through the distribution network. Since the current distribution network cannot be monitored in real time, it is basically caused by a heating fault at the connection of the power cable head wire, burning out and power outage. The user will notify the maintenance personnel to carry out equipment maintenance. The long dragging time will have a great impact on the power failure of users, so the reliability of power supply is low, and the equipment damage rate is high, which cannot meet the requirements of the continuous improvement of people's living standards. If the cable head over-temperature remote alarm technology can be fully promoted and applied, online monitoring and intelligent alarm can be realized.
