Problems solved by technology
The wired method is only suitable for small-scale and relatively dense places to be measured, and there are problems such as heavy workload during installation and difficult maintenance
The wireless connection method has the advantage of not being limited by distance. However, since the temperature monitoring terminal used in the wireless method needs battery power supply, there are problems that the battery needs to be replaced and the subsequent maintenance workload is large.

The invention discloses a system for monitoring a cable temperature. The system comprises a temperature collection terminal, a zigbee central node, an intelligent gateway, a monitoring platform and acommunication network. The temperature collection terminal comprises a temperature sensor and a zigbee communication unit, and the temperature collection terminal is used to collect temperature data of a cable. The zigbee communication unit transmits the temperature data to the zigbee central node, and the zigbee central node collects the data of the plurality of temperature collection terminals and then transmits the data to the intelligent gateway. The intelligent gateway receives the temperature data from the zigbee central node and transmits the temperature data to the monitoring platform.The monitoring platform is used to receive the temperature data from the intelligent gateway to monitor whether the temperature of the cable exceeds a temperature threshold. The temperature of the cable can be effectively collected and monitored during an equipment operation process. The system has characteristics that networking is easy; installation is simple; and cost is low and so on.
Description
technical field [0001] The invention relates to the field of energy technology, in particular to a system for monitoring cable temperature. Background technique [0002] In the long-term operation of the power cables inside the switchgear, there will be potential safety hazards and failure hazards such as aging and wear, insulation damage, and increased contact resistance. For example, cable joints, whose continuous heating can easily lead to excessive local temperature rise. If there is no effective monitoring of the position where the cables in the switchgear are prone to heating and countermeasures are taken, it will affect the operating status of the high-voltage switchgear and even cause a fire. Therefore, monitoring the temperature of the position where the cable is prone to heat is a means to achieve pre-elimination of faults and ensure the normal operation of the high-voltage switchgear. [0003] There are mainly two methods for monitoring the temperature of existi...
