摘要：配电系统是由多种配电设备和配电设施所组成的变换电压和直接向终端用户分配电能的一个电力网络系统。由于配电系统作为电力系统的一个环节直接面向终端用户，它的完善与否直接关系着广大用户的用电可靠性和用电质量，因而在电力系统中具有重要的地位。因此，为避免因温度高，导致设备老化，设备烧坏，供电中断，一次设备起*炸等严重事故，对各电气节点进行长期的温度监测能避免因严重故障，造成用户的人身伤害及经济损失。

Abstract: The power distribution system is a power network system that is composed of a variety of power distribution equipment and power distribution facilities to transform voltage and directly distribute electrical energy to end users. As a part of the power system, the power distribution system directly faces end users, and its perfection directly affects the reliability and quality of power consumption of the majority of users, so it has an important position in the power system. Therefore, in order to avoid serious accidents such as equipment aging, equipment burnout, power supply interruption, fire and explosion of equipment due to high temperature, long-term temperature monitoring of each electrical node can avoid serious failures that may cause personal injury and economic loss to users.
